Cordova plugin to allow cross origin requests (CORS) with WKWebView on iOS.

cordova-plugin-cors

Allow cross origin request (CORS) with WKWebView on iOS.

This plugin should be compatible with every plugin providing a WKWebView engine for Cordova and has been tested with cordova-plugin-wkwebview-engine and cordova-plugin-ionic-webview.

Installation

cordova plugin add cordova-plugin-cors

Usage

This plugin replaces the XMLHttpRequest object. There is no code modification required. It should work seamlessly.

It has been tested with pure Javascript code and with Angular HttpClient object.

Zone.js support is also integrated. Event listeners will be called within the zone used when calling send().

Example

var request = new XMLHttpRequest();
request.open('GET', 'https://cordova.apache.org', true);

request.onreadystatechange = function(event) {
    if (this.readyState === XMLHttpRequest.DONE) {
        if (this.status === 200) {
            console.info('Cross origin request was sent with success!', this.responseText);
        } else {
            console.error('Cross origin request failed :(', this.status, this.statusText);
        }
    }
};

request.send(null);

Limitations

Synchronous requests are not supported.

cordova-plugin-cors's Issues

App crashing when try to make HTTP calls from Axios

In my cordova application using axios javascript library to make Http/Https calls. When I make API calls from XMLHttpRequest working properly. The problem is only with Axios.

Can you help on this?

Axios Library for reference.

App crashing when HTTP call has **accept=application/pdf**

I am using this Cordova plugin in my Cordova application. This plugin saved me a lot of my time. It worked for all my cases except the 1 following case.

Whem I am making API with https://vsltst1.applaudsolutions.com/OA_HTML/applaud/api/assignments/259/oracle-payslips/US/8809896?_accept=application/pdf&inline=true&biPublisherTemplate=# app got broken. After I debug got to know it's because of accept query parameter.

If I change from application/pdf to application/json it's working. seems like Mime-types not handled properly. @Raphcal Could you please help with this?

cordova ios 6.1.0 wkwebview all xhr POST requests failing and are converting as blob request.

Hi,

I have migrated the Cordova app from UIWebview to WKWebview.I have a native scanner screen that is invoked from the webpage and to invoke this I am using the "cordova-plugin-cors".
Which is working fine by launching a scanner. But on the same page, the other ajax post calls are getting failed and they are converted as blob requests, along with that it gives certificate trust error logs.

I tried removing the "cordova-plugin-cors" plugin post that all the post ajax call works perfectly. But Scanner will not be invoked without xhr plugin.

All the calls are getting invoked using the xhr.js file where the post calls are failing.
Can someone please help me to fix this issue?
