I am creating a phonegap app that needs to support android gingerbread. The gingerbread device cannot successfully make ajax requests to the service API. No other device appears to have this problem. I always get back:
HTTP Error 411. The request must be chunked or have a content length.
Some searching has indicated this is usually not a device-specific error. Here is the code I am using:
var addItemToList = function (itemId, successCallback, errorCallback) {
var address = appContext.createEndPointAddress("/List/" + itemId);
$.ajax({
type: 'PUT',
url: address,
dataType: "json",
success: successCallback,
error: errorCallback,
headers: {
"Authorization": appContext.getAuthHeader(),
Accept:
"application/site.error-ver1+json, application/site.success-ver1+json"
}
});
};
I am assuming it has to do with the request header formed by whatever browser gingerbread uses. What should I do to repair the faulty header?
Fixed the issue. Apparently, PUT requests are not normally created without a body. Thus, adding the line:
data: "{}",
fixed the problem.

I'm sending an Jquery.Ajax request to a server which is hosting a .asmx web service.
jQuery.ajax({
type: 'GET',
url: 'http://IP-destination/myFolder/WebService.asmx/LogonUser',
cache: 'true',
data: {
'username':get_cookie('username'),
'password':get_cookie('password'),
'environment':get_cookie('environment')
},
dataType: 'jsonp',
beforeSend: function(){$.mobile.loading('show', 'a', 'Laddar...', false); alert("go");},
error: function(a, b, c){
$.mobile.loading('hide','a');
alert(a + b+ c);
},
success: function(response){
$.mobile.loading('hide','a');
alert("success");
self.loginUser_cb(response);
}
});
While sending data through my browser, emulator or "Legacy Hybrid build (Intel XDK) for android" everything works great.
But when I use Cordova (still android, works on IOS) the request get an "500 Internal Server Error".
It seems like my URL is missing my data parameters:
http://oi60.tinypic.com/21jvb5y.jpg
When I use my browser the URL is correct with the data parameter in the end of the url: /LogonUser?callback=jQuery19105695250731240461_1425028837473&username=MyUserName&password=Secret&environment=Dev
My question is: What could possibly cause this in Cordova Android but work great
in the emulator/ios/Hybrid Legacy build? The URL seem to be cut short.
I'd look to simplify things as much as possible and see if the get_cookie portion is failing for you. Try removing that and using static values. If it works, it means your cookies may not exist as you think they should and you should write logic to handle that.
I'am develoing a VB.NET MVC4 Web App using Android's webView to run it.
I have the next problem: When i make an ajax PUT request to my own controllers method, i recieve a 404 status code.
In the other hand, when i make a get or post petition, works fine. ¿Any idea?
$.ajax({
type: 'PUT',
url: 'myurl',
data: data,
success: function (json, textStatus) {
alert(json);
},
error: function (jqXHR) {
alert('error');
}
});
jqXHR.readystate = 4
jqXHR.message = server error file or directory not found
jqXHR,status: 404
EDIT: IIS is configured to work with PUT and DELETE and thanks to that it works correctly in the browser but not with the Androids WebView.
Your code is missing a quote url: 'myurl needs a ' on the end
$.ajax({
type: 'PUT',
url: 'myurl',
data: data,
success: function (json, textStatus) {
alert(json);
},
error: function (jqXHR) {
alert('error');
}
});
This might be an error in your example but that's all we can see to correct the other things to check is IIS Setup of the site does is it set to allow PUT, DELETE ect
GET & POST are standard and are enabled by default.
So please follow the answer to this question:
How do I enable HTTP PUT and DELETE for ASP.NET MVC in IIS?
I have a really weird behaviour on android app (Cordova 2.1).
I simple use code like that:
$.ajax({
type: "GET",
url: this.serverUrl,
data:data,
dataType: "json",
timeout: 3000, // in milliseconds
success: function(data) {
//never gets here...
},
error: function(request, status, err) {
//always gets here
console.log(request.responseText);
}
});
request.responseText always contains html-page with this content: http://dimalezhnev.ru/assets/tmp/html.txt (I placed the output in this file).
I draw a picture in my mind that browser while doing ajax request drop it and returns response with that html - forces user to update the browser in agressive style.
How to prevent it? I just can't imagine why is this happening now.
Currently trying to make an ajax post request to an IIS Express hosted MVC 4 Web API end point from an android VM (Bluestacks) on my machine. Here are the snippets of code that I am trying, and cannot get to work:
$.ajax({
type: "POST",
url: "http://10.0.2.2:28434/api/devices",
data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'}
}).always(function( data, textStatus, jqXHR ) {
alert( textStatus );
});
Whenever I run this request I always get back a textStatus of 'error'. After hours of trying different things, I pushed my End Point to an actual server, and was able to actually get responses back in PhoneGap if I built up an XMLHttpRequest by hand, like so:
var request = new XMLHttpRequest();
request.open("POST", "http://172.16.100.42/MobileRewards/api/devices", true);
request.onreadystatechange = function(){//Call a function when the state changes.
console.log("state = " + request.readyState);
console.log("status = " + request.status);
if (request.readyState == 4) {
if (request.status == 200 || request.status == 0) {
console.log("*" + request.responseText + "*");
}
}
}
request.send("{EncryptedPassword:1234,UserName:test,DeviceToken:d234}");
Unfortunately, if I try to use $.ajax() against the same end point in the snippet above I still get a status text that says 'error', here is that snippet for reference:
$.ajax({
type: "POST",
url: "http://172.16.100.42/MobileRewards/api/devices",
data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'}
}).always(function( data, textStatus, jqXHR ) {
alert( textStatus );
});
So really, there are a couple of questions here.
1) Why can't I get any ajax calls (post or get) to successfully hit my End Point when it's hosted via IIS Express on the same machine that the Android VM is running?
2) When my end point is hosted on an actual server, through IIS and served through port 80, why can't I get post requests to be successful when I use jquery's ajax calls? (Even though I can get it to work by manually creating an XMLHttpRequest)
Thanks
Are you sure that BlueStacks uses the same host IP (10.0.2.2) as the emulator? I'm not familiar with it so I'm not sure what the answer to that is.
jQuery wants the data to be a string, try:
data: JSON.stringify({'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'});
and for good measure, add
contentType: 'application/json',
in your ajax settings.
To anyone who ever looks this up, the issue ended up being the port that IIS Express was using on my local machine. When I got things to route through port 80, everything worked okay.
I have the following Problem. In the Phonegap App(for Android) I want to make an AJAX-Call to connect with a Sharepoint Server, with the following Code:
$.ajax({
url:"https://xxx/_vti_bin/lists.asmx",
beforeSend: function( xhr ){
xhr.setRequestHeader(
"SOAPAction",
"http://schemas.microsoft.com/sharepoint/soap/GetListCollection"
);
xhr.setRequestHeader("Content-Type","text/xml; charset=utf-8");
},
dataType:"xml",
contentType: "application/xml; charset=utf-8",
timeout:10000,
type:'POST',
cache: false,
username: "username",
password: "password",
data: soapEnv,
success:function(data) {
// alert data
var serializer = new XMLSerializer();
serialized = serializer.serializeToString(data);
alert(serialized);
},
error:function(XMLHttpRequest,textStatus, errorThrown) {
// alert errors
alert("Error status :"+textStatus);
alert("Error type :"+errorThrown);
alert("Error message :"+XMLHttpRequest.responseXML);
alert("Error statustext :"+XMLHttpRequest.statusText);
alert("Error request status :"+XMLHttpRequest.status);
},
complete: function(jqXHR, textStatus){
alert(textStatus);
}
});
When I try to run it on the Android Emulator the error messages are:
Error status: error
Error type:
Error message: undefined
Error statustext: error
Error request status: 0
However when I try to run it on my Browser (Chrome) with disabled websecurity (because of same origin policy) it works all fine. Phonegap normally shouldn't care about SOP because of the file:/// Protocol. I added the following to 'mobileinit':
$(document).bind("mobileinit", function() {
$.support.cors = true;
$.mobile.allowCrossDomainPages = true;
});
But when I run the same Code in Chrome without websecurity disabled, I get exactly the same errors as in the Android Emulator.
I also tried an AJAX call to wikipedia (with html instead of xml, and GET instead of POST), and that worked without a problem.
Also I think the AJAX to Sharepoint doesn't even get fired (no traffic in Fiddler2, if I managed to configure it the right way)
So I am really stuck with this problem since 2 days now, if anyone knows how to make this ajax call work, it would made me so happy :-)
(soapEnv is the XML envelope, sent to the server)
Well I know that once upon a time jQuery had a bug where it treated a request status of 0 as an error. When running from the file protocol a status of 0 is the same this as a 200 (OK). You may need to update your version of jQuery.
Alternatively to test my theory just do a plain vanilla XHR request to your service to see if it works. Here is my stock example:
