AngularJS post request. Character changed from initial value - angularjs

Question

I have this very strange problem. I have a very long string as a token for an app. When i`m doing the http post request, the string changes.
From the ending of "Vow== 256220" it is changing to "Vow: = 256220" and i do not understand why.
Here is the code if helps:
var request = $http({
method: "post",
url: urlWS,
data: {token: token},0
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
});
request.success(function (data) {
alert(data);
});

Answer 1

Following code working for me.
$http({
method: "post",
url: urlWS,
data: 'token='+encodeURIComponent("Vow== 256220"),
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
});
request.success(function (data) {
alert(data);
});
May be above solution solve your problem.

You will have to configure $httpProvider in your main module config function. This is been done with transformRequest method by firstly adding the default header you have added and then transforming the request.
Add the following code to you main config function module:
$httpProvider.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
// post headers
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
$httpProvider.defaults.transformRequest = [function(data) {
return angular.isObject(data) && String(data) !== '[object File]' ? $.param(data) : data;
}];
I hope it helps ;)
