swisspol / gcdwebserver Goto Github PK

I'm trying to use GCDWebUploader on an iOS 8 only project using CocoaPods.

My code is as follows (on a View Controller):

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];

    self.server = [[GCDWebUploader alloc] initWithUploadDirectory:documentsPath];
    self.server.allowHiddenItems = YES;

    self.server.delegate = self;

    [self.server start];
}

The server starts, and I get
[INFO] GCDWebUploader started on port 8080 and reachable at http://192.168.1.111:8080/

on the console. However, as soon as I load the page, I get a blank page and this error is logged:

[EXCEPTION] *** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[1]

Any idea? Weirdly enough, if I run the project with pod try it works fine, and also if I clone it from Github and run the demo.

Some times when on WiFi network, starting the Web Server I get this log

   [INFO] GCDWebServer now reachable at (null)

Apparently it seems that I do not have any ip address.
In this case which of these delegates is called?

- (void)webServerDidStart:(GCDWebServer*)server {
}

 - (void)webServerDidConnect:(GCDWebServer*)server {
}

 - (void)webServerDidDisconnect:(GCDWebServer*)server {
 }

 - (void)webServerDidStop:(GCDWebServer*)server {
  }

In

• (void)_writeData:(NSData*)data withCompletionBlock:(WriteDataCompletionBlock)block {
  [data retain];
  dispatch_data_t buffer = dispatch_data_create(data.bytes, data.length, dispatch_get_current_queue(), ^{
  [data release];
  });
  [self _writeBuffer:buffer withCompletionBlock:block];
  dispatch_release(buffer);
  }

how to replace dispatch_get_current_queue() since its deprecated ?

Hi,

Is it possible to get file transfer progress feedback from the sever?

regards.

ok, so i subclassed the GCDWebServerConnection, and overrode the

(void)didWriteBytes:(const void*)bytes length:(NSUInteger)length{
[[NSNotificationCenter defaultCenter] postNotificationName:SERVER_ASSET_UPLOAD_PROGRESS object:self userInfo:dict];
[super didWriteBytes:bytes length:length];
}
nothing else. and call

[self.server startWithOptions: @{GCDWebServerOption_ConnectionClass:NSStringFromClass([MYGCDWebServerConnection class])} error:&error];

I receive no errors ,but when the first request comes in, The app crashes with

if i remove the option, and just call start, everything works fine.
but then i dont receive the notifications i've aded to my custom class.

will a 64 bit version be available ?

Does it possible to run server without wifi connection (and 3G/LTE)?
For example, when current device is the only one client for this server. When i tried to use GCDAsyncSocket, accept() function creates listening server at 0.0.0.0:port.
I mean, for PC version it is normal to use localhost. But, i guess for iPhone/iPad it is not possible. Am i right?
Thank you.

Hi,
When server request is mp4 files, I want to response changed other mp4 from NSdata formatted. I research many times. But I haven't solve problem. How can I use GCDWebServerStreamedResponse class?. Please help me?

I get a broken pipe error when sending an 11MB mp4 file through the socket

If I install GCDWebServer via CocoaPods I only get the "Core" and the "Support Files" folder. The "Requests" and the "Responses" folders are missing :-(

Did I something wrong?

Ralph

Summary: GCDWebUploader does nothing to prevent uploading and deleting files outside of uploadDirectory. This can be accomplished by using .. path components in the path parameter in a POST /upload or POST /delete.

Expected Behavior: Attempting to upload or delete a file outside of uploadDirectory will fail.

Actual Behavior: Attempting to upload or delete a file outside of uploadDirectory succeeds.

Notes: It isn't entirely clear whether this behavior is desired or not. I wanted to disable it, so I check the path in the appropriate -*should methods in a GCDWebUploader subclass.

Hi Pierre

If I directly open the server after start server, the mobile safari may not fetch the content sometimes, do you know how to detect the server is really ok? Did i need to delay open url?

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
  _window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
  _window.backgroundColor = [UIColor whiteColor];
  [_window makeKeyAndVisible];

  _webServer = [[GCDWebServer alloc] init];
  [_webServer addDefaultHandlerForMethod:@"GET"
                            requestClass:[GCDWebServerRequest class]
                            processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {

    return [GCDWebServerDataResponse responseWithHTML:@"<html><body><p>Hello World</p></body></html>"];

  }];
  [_webServer start];

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://localhost:8080"]];
  return YES;
}

I created a GCDWebserver instance and call start method. The start method returns true even without wifi connected !.

How to detect server Connected / Disconnected ?

Can't figure out how to build a Swift project using GCDWebserver in XCode 6.0 (bèta).

Steps:

• Added entire "GCDWebServer" subfolder to Xcode project
• Added bridging header

When building, I get the following error:

Undefined symbols for architecture x86_64:
  "_deflate", referenced from:
      -[GCDWebServerGZipEncoder readData:] in GCDWebServerResponse.o
  "_deflateEnd", referenced from:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any ideas?

Changing the name to a custom one when publishing, the device become unreachable. Using the default one instead, the web server provide the content correctly.
Any suggestion?

How can I hide these ?

Hi, thanks for the great work. I tried using the web server when off wifi, however the ip address shows null after launch. Is it possible to use it that way?

So here is the situation, I have a bunch of unit tests that are running with a dependency on GCDWebServer. Here is the ordering of events:

• Test setup method starts.
• Singleton class that includes a GCDWebServer object is sent a start method. Singleton class is the delegate for GCDWebServer.
• Start method on singleton adds handlers and then calls startWithOptions: on the GCDWebServer property.
• Singleton returns void to caller.
• Test setup method starts waiting for an NSNotification from the Singleton before continuing.
• Singleton receives webServerDidStart: method.
• Singleton sends notification.
• Test setup method receives notification and continues with test.

Here are some things I noticed:

• Tests always pass in Xcode on my (fast) local machine but consistently fail on Travis and will sometimes (but not consistently) fail when run at the command line locally using xcodebuild with xcpretty.
• The failures are always related to the server not being reachable and look like this:
  
  Note that I am setting the HTTP client base URL using the serverURL property returned by GCDWebServer.
• Most tellingly I have a test which does the following: Runs the test setups above, then does a simple poll of GCDWebServer on the isRunning property with an assert that it must be true. That test is also failing whenever this happens.
  

Anyway what all this SEEMS to point to is that the delegate is receiving a callback before the server is ready to accept connections. I see the following potential solutions to this problem:

• Use the method webServerDidCompleteBonjourRegistration: to fire the notification event from the singleton and start the tests. This works but it slows down the tests by several orders of magnitude.
• Since the isRunning property test is failing I'm assuming it knows that the server is not ready for connections. As such I could use KVO on the isRunning setter property Running but since it looks like the getter is using the ivar _source I suspect that the Running property isn't really being used for setting the isRunning state but I might try it and see or take a harder look at the code.
• I could introduce a brief wait state after receiving the delegate callback before posting the notification. As you can imagine I REALLY don't like this idea.

Have you got any suggestions? The runWithOptions: method mentions starting the server synchronously and I could use that instead of the delegate callback but the documentation isn't clear on what the blocking event is (I'll check the code but I imagine its something that might be good to clarify). I also don't see any other delegate callback methods that would work for this (or NSNotification constants) but maybe I'm missing something.

Would also fix compatibly issues with ARC host projects automatically.

Hi, I did a class extension of GCDWebServer and GCDWebServerConnection so that I could track the starting, ending and progress of data being sent to a client. I also had to add some code to the connection class:

      [self willChangeValueForKey:@"totalBytesWritten"];
    _bytesWritten += size;
      [self didChangeValueForKey:@"totalBytesWritten"];

Which enabled the KVO tracking. Thought you might want to add this to the class - unless there is another way to do it :-)

GCDWebServer / GCDWebServer / Core / GCDWebServer.m (523-527)

NSTask* task = [[NSTask alloc] init];
 [task setLaunchPath:@"/usr/bin/opendiff"];
[task setArguments:@[expectedPath, actualPath]];
[task launch];
ARC_RELEASE(task);

Can't compile source files because of the NSTask which is not supported under iOS.
Btw, thank you. Mac-version works perfect.

We currently observe a crash in [GCDWebServer startWithOptions:error:]:620 that occurs because _options are still set. We do check if the server is running before starting it, but the isRunning method only check if _source is set. Unfortunately I wasn't able to reproduce these crashes. It might be related to specific scenarios involving the background mode. Any hints on how this might be addressed?Is there a particular reason why it needs to abort in start if _options are set and abort in stop if not?

When I run this HTML file I eventually get a crash. The file is "video.html". It is just calling itself every 7 seconds. I am serving using GET

The problem seems to be with accessing MPAVItem.

The files "video.html" and "Fishmonger-Salmon_01_2.mp4" are being served locally. You can get a copy of the original mp4 from here http://kikkit-demo.s3.amazonaws.com/dev/Preview/370/Fishmonger-Salmon_01_2.mp4

Is there any way I can bind to 127.0.0.1 only?

Loving GCDWebserver so far!

I tried to serve an audio data file from user ipod library:

   return [GCDWebServerDataResponse responseWithData:data contentType:@"audio/mp4"];

where data is the NSData * from a MPMediaItem.

I have this log when the url handler is called

    [DEBUG] Did open connection on socket 34
    [DEBUG] Connection received 320 bytes on socket 34
    [DEBUG] Connection on socket 34 processing GET request for "/audioData" (0 bytes body)

    // idem several times

At the second call I have the same response and

 [DEBUG] Did close connection on socket 34

To me it seems that the response body is 0 bytes

   [DEBUG] Connection on socket 34 processing GET request for "/audioData" (0 bytes body)

but my NSData is actually filled in.
Where I'm wrong?

I want to preface by saying it is entirely possible that the fault is somewhere in my code but I can't find an obvious place that would be leaking on my side. I can consistently reproduce this doing the following:

1. Add a handler of a POST action to GCDWebServer.
2. POST to the handled endpoint.
3. Watch the results.

Here's a link to the trace:

https://www.dropbox.com/sh/vv27heosugeym5y/_10rs09hI3

And here are some screenshots of the run:

The stack suggests that on my side the problem is in this method and even wrapping an autoreleasepool and manually nilling out the GCDWebServerDataRequest isn't doing it.

Title is all.
I tried GCDWebServer in OSX and iOS.

In iOS, the server process does not suspend a main thread.
But, in OSX it does.
I don't think up goot workaround, thank you.

See https://github.com/swisspol/ComicFlow/issues/31 for details

I've planned to develop in-app API proxy server with GCDWebServer and AFNetworking. Because of not every maintainer provide clean API for their service=(

As you know, AFNetworking use GCD callback system. GCDWebServer works in sync mode and I must sync AFNetworking callbacks in handler.

May be, you'll redesign handler system as it done in Express.js by passing callback as parameter in processBlock instead of return value? Something like this:

typedef void (^GCDWebServerResponseBlock)(GCDWebServerResponse* response);
typedef void (^GCDWebServerProcessBlock)(GCDWebServerRequest* request, GCDWebServerResponseBlock responseCallback);

There are several problems with contentLength.

For one I think it should be of type unsigned long long (also the return type of the fileSize property in NSFileAttributes). Currently we're running into problems with files larger than 4 GB (which is not an unlikely scenario, i.e. using the webserver to stream HQ movies for AirPlay on local WiFi).

Furthermore using NSNotFound as a special value for contentLength is problematic.
The NSNotFound is NSIntegerMax which is NSUIntegerMax/2 and therefore totally within the range of contentLength.

I'd be glad to send a pull request for the first problem, but the second problem is more of a conceptual nature. Fixing problem no 1 doesn't make no 2 worse, so I'd suggest doing it anyway ;)

Any thoughts?

PS: still got much love for GCDWebServer! Thanks 🙇

When installed via CocoaPods in a new iOS project, building for the simulator fails with the following errors:

These are defined in <MobileCoreServices/UTType.h>, which is imported in GCDWebServerFunctions.m. When building from source, this works fine, but seems to fail as a pod, I assume because the framework isn't explicitly linked in the podspec.

Changing the Core subspec to the following seemed to fix it for me:

  s.subspec 'Core' do |cs|
    cs.source_files = 'GCDWebServer/**/*.{h,m}'
    cs.requires_arc = true
    cs.ios.framework = 'MobileCoreServices'
    cs.ios.library = 'z'
    cs.osx.framework = 'SystemConfiguration'
    cs.osx.library = 'z'

I was going to create a pull request, but it's a very small change and I wanted to see if there was a reason you weren't linking them by default.

See #45 for details

GCDWebServer is simple and powerful.
I want to implement a WebDAV server with it. And need support Chunked transfer encoding while handle PUT command.

Hi, I use responseWithData for send server 3.3 MB mp4 file. But not working . Then I tried to send NSData as Partial Content. Then I look your method - (instancetype)initWithFile:(NSString*)path byteRange:(NSRange)range isAttachment:(BOOL)attachment

Then this method inside used "Content-Range". I wrote new method use it same code in GCDWebServerDataResponse class. But I have a problem. My mp4 files length 34 second.
15 seconds, which works very well, but then gets stuck. Please help me. using a "Content-Range" need to find a way to send server.
I have written my code :

- (instancetype)initWithDataPartialContent:(NSData*)data contentType:(NSString*)contentType  byteRange:(NSRange)range{
    if (data == nil) {
        DNOT_REACHED();
        ARC_RELEASE(self);
        return nil;
    }
    struct stat info;
    if (GCDWebServerIsValidByteRange(range)) {
        if (range.location != NSNotFound) {
            range.location = MIN(range.location, (NSUInteger)info.st_size);
            range.length = MIN(range.length, (NSUInteger)info.st_size - range.location);
        } else {
            range.length = MIN(range.length, (NSUInteger)info.st_size);
            range.location = (NSUInteger)info.st_size - range.length;
        }
        if (range.length == 0) {
            ARC_RELEASE(self);
            return nil;  // TODO: Return 416 status code and "Content-Range: bytes */{file length}" header
        }
    }


    if ((self = [super init])) {
        _data = ARC_RETAIN(data);
        if (range.location != NSNotFound) {
            [self setStatusCode:kGCDWebServerHTTPStatusCode_PartialContent];
            [self setValue:[NSString stringWithFormat:@"bytes %i-%i/%i", (int)range.location, (int)(range.location + range.length - 1), (int)info.st_size] forAdditionalHeader:@"Content-Range"];
            //LOG_DEBUG(@"Using content bytes range [%i-%i] for file \"%@\"", (int)range.location, (int)(range.location + range.length - 1), path);
        }
        NSLog(@"RANGE Length %lu",(unsigned long)range.length);

        self.contentType = contentType;
        self.contentLength = (range.location != NSNotFound ? range.length : (NSUInteger)info.st_size);
        self.lastModifiedDate = _NSDateFromTimeSpec(&info.st_mtimespec);
        self.eTag = [NSString stringWithFormat:@"%llu/%li/%li", info.st_ino, info.st_mtimespec.tv_sec, info.st_mtimespec.tv_nsec];


        //self.contentLength = data.length;
    }
    return self;
}

static inline NSDate* _NSDateFromTimeSpec(const struct timespec* t) {
    return [NSDate dateWithTimeIntervalSince1970:((NSTimeInterval)t->tv_sec + (NSTimeInterval)t->tv_nsec / 1000000000.0)];
}

Seems like you could also use GCD for manage socket communication.

http://www.mikeash.com/pyblog/friday-qa-2009-12-11-a-gcd-case-study-building-an-http-server.html

This library looks great. Are you considering adding web socket support in the future?

Enabling warnings -Wshadow reveals some minor issues.

Example: The following lines are not easily understandable due to the re-use of the variable name buffer:

- (void)_readDataWithCompletionBlock:(ReadDataCompletionBlock)block {
  [self _readBufferWithLength:SIZE_T_MAX completionBlock:^(dispatch_data_t buffer) {

    if (buffer) {
      NSMutableData* data = [[NSMutableData alloc] initWithCapacity:dispatch_data_get_size(buffer)];
      dispatch_data_apply(buffer, ^bool(dispatch_data_t region, size_t offset, const void* buffer, size_t size) {
        [data appendBytes:buffer length:size];
        return true;
      });
      block(data);
      ARC_RELEASE(data);
    } else {
      block(nil);
    }

  }];
}

See #26 for an example use

I need decode file before send to response.
I create subclass WebServerDecryptedFileResponse of GCDWebServerFileResponse and overwrite method readData:

- (NSData *)readData:(NSError *__autoreleasing *)error
{
    NSData *readData = [super readData:error];

    if (readData.length != 0) {
      readData = [readData decodedData];
    }

    return readData;
}

Server starts with code:

    [_server addHandlerWithMatchBlock:^GCDWebServerRequest *(NSString* requestMethod, NSURL* requestURL, NSDictionary* requestHeaders, NSString* urlPath, NSDictionary* urlQuery) {

        if (![requestMethod isEqualToString:@"GET"]) {
            return nil;
        }

        return [[GCDWebServerRequest alloc] initWithMethod:requestMethod url:requestURL headers:requestHeaders path:urlPath query:urlQuery];

    } processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {

        GCDWebServerResponse* response = nil;
        NSString *filePath = [_path stringByAppendingPathComponent:request.path];
        BOOL isDirectory;

        if ([[NSFileManager defaultManager] fileExistsAtPath:filePath isDirectory:&isDirectory] && !isDirectory) {
            response = [WebServerDecryptedFileResponse responseWithFile:filePath];
        }

        if (!response) {
            response = [GCDWebServerResponse responseWithStatusCode:kGCDWebServerHTTPStatusCode_NotFound];
        }

        return response;
    }];

The problem is UIWebView did not load with error:
Code=-1005 "The network connection was lost.".

Method readData calls twice and the first time it seems all is well, but when readData with length 0 UIWebView show error.

What's wrong?
Thanks!

This header can be either set to the "ETag" or "Last-Modified" value for the entity. If they don't match the current values, the "Range" header should be ignored and the entire resource returned with a 200 status, otherwise only the required byte range should be returned with a 206 status.

Currently GCDWebServer implements the latter but not the former.

http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.27

And verify this works with http://cocoadocs.org/docsets/GCDWebServer/

It would be nice to have this project running on other platforms beside OS X. It could be accomplished by using GNUstep.
I've tried to make things work, but with poor success.
Main problem is the CFNetwork (mainly calls to CFNetServices ) and CoreServices dependancy.

I think that could be possible to port CFNetServices function calls to NSNetServices ( since it is implemented in GNUstep) and see what we could do for CoreServices call.

I'll give it a try when I can.
I opened an issue to let you know about that and ask you if there's something I've to know before starting working on it (maybe some hard reason why dependency on those framework cannot be removed)
And of course recruiting someone who would help me do it :D

I'm using GCDWebServer on OS X, and I'm finding that it's ignoring INT and TERM signals after a while running.

I'm using an NSApplication - a normal Cocoa app, but without any visible UI, to do some offscreen rendering and returning images over HTTP. I run the application binary directly from the command line Name.app/Contents/MacOS/Name.

After a period of running - sometimes as little as an hour, hitting Ctrl-C no longer stops the application, and the signal seems to be ignored. Performing a 'Quit' from Activity Monitor does the same. Only a 'Force Quit' terminates the application.

Even though I'm running from a command line application I'm using startWithOptions, not runWithOptions, because I don't want to lock the main thread, which is sometimes used by Cocoa internals for drawing.

Any idea what's going on?
