AngularJS Question

Ionic + Angular POST request return state 404

I just updated on the new version on the Angular + Ionic and method for processing remote request stopped working and returns always 404 response.

Request is following:

Request Method:POST
Status Code:404 Not Found (from cache)
Request Headersview source
Accept:application/json, text/plain, */*
User-Agent:Mozilla/5.0 (Linux; Android 4.4.2; Lenovo Build/KOT49H) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/ Mobile Safari/537.36
Request Payloadview source

Code of the method which is processing remote request is following:

// set transfer credentials
method : 'POST',
url : $scope.remoteUrl,
data: {img_base64: "/9j/4AAQSkZ"},
headers: 'application/json',
timeout: 10000
// success response
}).success(function(data, status, headers, config) {
} else {

// error response
}).error(function(data, status, headers, config) {

I tried to solve it using this topic:

AngularJs $ does not send data


Angular + Ionic Post request getting 404 not found

But without luck.

Server side is processing request by this way:

$inputJSON = file_get_contents('php://input');
$input= json_decode( $inputJSON, TRUE ); //convert JSON into array

If i'm trying to send request using Postman or Curl everything seems to be working.

Ionic info:

Node Version: v0.12.2
Cordova CLI: 5.0.0
Ionic CLI Version: 1.3.22
Xcode version: Xcode 6.3.1 Build version 6D1002
ios-sim version: Not installed
ios-deploy version: Not installed

AngularJS version:

"version": "1.3.13",

How can i solve it please?

Many thanks for any advice


Hum, I just ran into the same problem: the header suggests it has been fetched from cache... But actually, it seems it has to do with a new security policy in new versions of Cordova.

Here's how I solved it:

I installed Cordova's whitelist plugin :

cordova plugin add cordova-plugin-whitelist

Then, add your content policy in your index.html as a meta tag (using your own host or '*' for accepting all requests) :

<meta http-equiv="Content-Security-Policy" content="default-src 'self' ws://localhost:35729 data: gap:; style-src 'self' 'unsafe-inline'; media-src *;script-src 'self' localhost:35729 'unsafe-eval' 'unsafe-inline';">

default-src is used for general requests; the ws://localhost:35729 host is used for live-reload in ionic serve.

script-src is used for secure script execution

unsafe-inline and unsafe-eval are required in order for angular to work properly.

data: gap: is only used on iOS.

self means the current host of the index.html file.

You'll have to add your own in order for your requests to work. Don't forget to add the protocol and the port if they're non-standard

You can skip the meta tag if you don't want it, but you'll get a lot of warnings from the whitelist plugin.

More info on how to configure this in the plugin's readme.

Then rebuild your app, and it should work again.
