PhoneGap Issues with ajax and jsonp

Question

I want to issue an AJAX call to my remote server, upload a few parameters and download some content. This script works perfectly in a browser, but doesn't work with PhoneGap (testing on Ripple, chrome).

I have looked at problems and solutions such as:

PhoneGap not issuing AJAX (jsonp) request

Issues with jQuery, ajax, and jsonp

Ajax call:

$.ajax({
        url: "https://mydomain.com/file.php",
        data: {test:"test"},    
        type: 'GET',
        dataType: 'jsonp',
        timeout: 5000,
        success: function(data){
            if(data['var'] == 'correct'){ 
                notifyAlert('correct','Login');
            }else{
                notifyAlert('incorrect','Login');
            }       
        },          
        error: function(x,e){
            if(x.status==0){
                notifyAlert('You are offline!!\n Please Check Your Network.', 'Error');
            }else if(x.status==404){
                notifyAlert('Requested URL not found.', 'Error');
            }else if(x.status==500){
                notifyAlert('Internel Server Error.', 'Error');
            }else if(e=='parsererror'){
                notifyAlert('Error.\nParsing JSON Request failed. '+x.status, 'Error');
            }else if(e=='timeout'){
                notifyAlert('Request Time out.');
            }else {
                notifyAlert('Unknow Error.\n'+x.responseText, 'Error');
            }       
        }
    });

Remote server code:

$record = array('var' => 'correct');
echo $_GET['callback'] . '(' . json_encode($record) . ');';

My config.xml file has:

<access origin="https://mydomain.com" />

When testing on Ripple (emulator) it gives me the status 0 error. When testing te same script on my local server (through the browser) it gives me the correct var alert.

I also tested a json call and this works perfectly in the emulator but it doesn't work when I upload the apk to my phone. Same result as the problem above with jsonp (status 0 error).

Answer 1

Finally found the problem. It was a problem with my SSL certificate. I tested on a server with a unsigned certificate which gave me the incorrect response. Using a signed certificate resolved all my problems..
