4D plugin implementation of libcurl and curl

4d-plugin-curl

This is a 4D plugin implementation of libcurl and cURL.

Important

This plugin project is a forked subset of what was published as OAuth.

Existing cURL@ commands have the same name and functionality, but their tokens (internal IDs) have changed.

To migrate existing methods, do the following:

1. Comment the code that calls cURL@ plugin commands.
2. Close 4DB.
3. Replace the plugin.
4. Uncomment the code.

cURL Get executable

Returns the path to the curl executable embedded in the plugin. You can use this with LAUNCH EXTERNAL PROCESS.

Example

version

$version:=cURL Get version 
  //libcurl/7.40.0 OpenSSL/1.0.1j zlib/1.2.8 libidn/1.29 libssh2/1.4.3

$path:=cURL Get executable 

$stdOut:=""
$stdIn:=""
$stdErr:=""

LAUNCH EXTERNAL PROCESS($path+" -V";$stdIn;$stdOut;$stdErr);

Remarks

On Mac, SSH2 is linked to the system OpenSSL located at /usr/lib/, not the one embedded in the plugin. This is to avoid crash with SFTP.

On Windows, OPENSSL (LIBEAY and LIBSSL) and LIBSSH2 are statically linked to LIBCURL, to avoid collision with the DLL included in 4D itself.

LIBCURL is modified so that it will yield to 4D during a long operation (easy.c).
