I'm trying to add a post request to a button in my ionic app but I've found that adding the code makes the app useless. Not a single thing responds to any of my taps. Removing the code makes things normal again. This is all I have added:
$scope.powerPrompt = function() {
var pwr = alert("Power On");
$http.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
$http({
method: 'POST',
url: 'url',
data: "string"
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function(response) {
// handle success things
})
.error(function(data, status, headers, config) {
// handle error things
})
};
If I delete everything inside the powerPrompt function except the var pwr line, the rest of my app works. What's causing this? Do I have a syntax issue?
You are missing a , after the data property
$scope.powerPrompt = function() {
var pwr = alert("Power On");
$http.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
$http({
method: 'POST',
url: 'url',
data: "string",
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function(response) {
// handle success things
})
.error(function(data, status, headers, config) {
// handle error things
})
};
I am trying to achieve a login functionality using Angular JS on front-end and PHP + Zend on the back-end. Below is the code snippet of the angular js controller. This doesn't redirect the user to the appropriate page and while debugging, the control doesn't enter the success part but enters the error part with data being NULL. However if I put the $http part outside the function, atleast the control enters the success part with data being that of the next page to be redirected.
What could i be missing and what is the correct way to achieve the redirection?
In the below code the control doesn't enter the success section.
var myApp = angular.module('myApp',[]);
myApp.controller('loginCtrl', function ($scope, $http) {
$scope.authenticatelogin = function () {
$http({
url: "/admin/auth/authenticatelogin",
method: "POST",
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: $.param({login: $scope.login, password: $scope.password, rememberMe: $scope.remember})
}).success(function(data, status, headers, config) {
$window.location.href= "index/index";
$scope.data = data;
}).error(function(data, status, headers, config) {
$scope.status = status;
});
};
});
In the below code the control enters the success section.
var myApp = angular.module('myApp',[]);
myApp.controller('loginCtrl', function ($scope, $http) {
$http({
url: "/admin/auth/authenticatelogin",
method: "POST",
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: $.param({login: 'abc#abc.com', password: 'xyzxyz', rememberMe: ''})
}).success(function(data, status, headers, config) {
$window.location.href= "index/index";
$scope.data = data;
}).error(function(data, status, headers, config) {
$scope.status = status;
});
});
I would rather go for success/error callbacks to be part of the then method.
From angular documentation for version 1.4.5:
The $http legacy promise methods success and error have been
deprecated. Use the standard then method instead. If
$httpProvider.useLegacyPromiseExtensions is set to false then these
methods will throw $http/legacy error.
Try this one, although if you say that your code works outside the closure, it might not be the solution you are looking for:
$http({
url: "/admin/auth/authenticatelogin",
method: "POST",
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: $.param({login: $scope.login, password: $scope.password, rememberMe: $scope.remember})
}).then(function(data, status, headers, config) {
$window.location.href= "index/index";
$scope.data = data;
}, function(data, status, headers, config) {
$scope.status = status;
});
I am new to AngularJS, and for a start, I thought to develop a new application using only AngularJS.
I am trying to make an AJAX call to the server side, using $http from my Angular App.
For sending the parameters, I tried the following:
$http({
method: "post",
url: URL,
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: $.param({username: $scope.userName, password: $scope.password})
}).success(function(result){
console.log(result);
});
This is working, but it is using jQuery as well at $.param. For removing the dependency on jQuery, I tried:
data: {username: $scope.userName, password: $scope.password}
but this seemed to fail. Then I tried params:
params: {username: $scope.userName, password: $scope.password}
but this also seemed to fail. Then I tried JSON.stringify:
data: JSON.stringify({username: $scope.userName, password: $scope.password})
I found these possible answers to my quest, but was unsuccessful. Am I doing something wrong? I am sure, AngularJS would provide this functionality, but how?
I think you need to do is to transform your data from object not to JSON string, but to url params.
From Ben Nadel's blog.
By default, the $http service will transform the outgoing request by
serializing the data as JSON and then posting it with the content-
type, "application/json". When we want to post the value as a FORM
post, we need to change the serialization algorithm and post the data
with the content-type, "application/x-www-form-urlencoded".
Example from here.
$http({
method: 'POST',
url: url,
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
transformRequest: function(obj) {
var str = [];
for(var p in obj)
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
return str.join("&");
},
data: {username: $scope.userName, password: $scope.password}
}).then(function () {});
UPDATE
To use new services added with AngularJS V1.4, see
URL-encoding variables using only AngularJS services
URL-encoding variables using only AngularJS services
With AngularJS 1.4 and up, two services can handle the process of url-encoding data for POST requests, eliminating the need to manipulate the data with transformRequest or using external dependencies like jQuery:
$httpParamSerializerJQLike - a serializer inspired by jQuery's .param() (recommended)
$httpParamSerializer - a serializer used by Angular itself for GET requests
Example with $http()
$http({
url: 'some/api/endpoint',
method: 'POST',
data: $httpParamSerializerJQLike($scope.appForm.data), // Make sure to inject the service you choose to the controller
headers: {
'Content-Type': 'application/x-www-form-urlencoded' // Note the appropriate header
}
}).then(function(response) { /* do something here */ });
See a more verbose Plunker demo
Example with $http.post()
$http.post(
'some/api/endpoint',
data: $httpParamSerializerJQLike($scope.appForm.data), // Make sure to inject the service you choose to the controller
{
headers: {
'Content-Type': 'application/x-www-form-urlencoded' // Note the appropriate header
}
}
).then(function
How are $httpParamSerializerJQLike and $httpParamSerializer different
In general, it seems $httpParamSerializer uses less "traditional" url-encoding format than $httpParamSerializerJQLike when it comes to complex data structures.
For example (ignoring percent encoding of brackets):
• Encoding an array
{sites:['google', 'Facebook']} // Object with array property
sites[]=google&sites[]=facebook // Result with $httpParamSerializerJQLike
sites=google&sites=facebook // Result with $httpParamSerializer
• Encoding an object
{address: {city: 'LA', country: 'USA'}} // Object with object property
address[city]=LA&address[country]=USA // Result with $httpParamSerializerJQLike
address={"city": "LA", country: "USA"} // Result with $httpParamSerializer
All of these look like overkill (or don't work)... just do this:
$http.post(loginUrl, `username=${ encodeURIComponent(username) }` +
`&password=${ encodeURIComponent(password) }` +
'&grant_type=password'
).success(function (data) {
The problem is the JSON string format, You can use a simple URL string in data:
$http({
method: 'POST',
url: url,
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: 'username='+$scope.userName+'&password='+$scope.password
}).success(function () {});
Here is the way it should be (and please no backend changes ... certainly not ... if your front stack does not support application/x-www-form-urlencoded, then throw it away ... hopefully AngularJS does !
$http({
method: 'POST',
url: 'api_endpoint',
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: 'username='+$scope.username+'&password='+$scope.password
}).then(function(response) {
// on success
}, function(response) {
// on error
});
Works like a charm with AngularJS 1.5
People, let give u some advice:
use promises .then(success, error) when dealing with $http, forget about .sucess and .error callbacks (as they are being deprecated)
From the angularjs site here "You can no longer use the JSON_CALLBACK string as a placeholder for specifying where the callback parameter value should go."
If your data model is more complex that just a username and a password, you can still do that (as suggested above)
$http({
method: 'POST',
url: 'api_endpoint',
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: json_formatted_data,
transformRequest: function(data, headers) {
return transform_json_to_urlcoded(data); // iterate over fields and chain key=value separated with &, using encodeURIComponent javascript function
}
}).then(function(response) {
// on succes
}, function(response) {
// on error
});
Document for the encodeURIComponent can be found here
If it is a form try changing the header to:
headers[ "Content-type" ] = "application/x-www-form-urlencoded; charset=utf-8";
and if it is not a form and a simple json then try this header:
headers[ "Content-type" ] = "application/json";
From the $http docs this should work..
$http.post(url, data,{headers: {'Content-Type': 'application/x-www-form-urlencoded'}})
.success(function(response) {
// your code...
});
$http({
method: "POST",
url: "/server.php",
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
data: "name='Олег'&age='28'",
}).success(function(data, status) {
console.log(data);
console.log(status);
});
you need to post plain javascript object, nothing else
var request = $http({
method: "post",
url: "process.cfm",
transformRequest: transformRequestAsFormPost,
data: { id: 4, name: "Kim" }
});
request.success(
function( data ) {
$scope.localData = data;
}
);
if you have php as back-end then you will need to do some more modification.. checkout this link for fixing php server side
Though a late answer, I found angular UrlSearchParams worked very well for me, it takes care of the encoding of parameters as well.
let params = new URLSearchParams();
params.set("abc", "def");
let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded'});
let options = new RequestOptions({ headers: headers, withCredentials: true });
this.http
.post(UrlUtil.getOptionSubmitUrl(parentSubcatId), params, options)
.catch();
This worked for me. I use angular for front-end and laravel php for back-end. In my project, angular web sends json data to laravel back-end.
This is my angular controller.
var angularJsApp= angular.module('angularJsApp',[]);
angularJsApp.controller('MainCtrl', function ($scope ,$http) {
$scope.userName ="Victoria";
$scope.password ="password"
$http({
method :'POST',
url:'http://api.mywebsite.com.localhost/httpTest?callback=JSON_CALLBACK',
data: { username : $scope.userName , password: $scope.password},
headers: {'Content-Type': 'application/json'}
}).success(function (data, status, headers, config) {
console.log('status',status);
console.log('data',status);
console.log('headers',status);
});
});
This is my php back-end laravel controller.
public function httpTest(){
if (Input::has('username')) {
$user =Input::all();
return Response::json($user)->setCallback(Input::get('callback'));
}
}
This is my laravel routing
Route::post('httpTest','HttpTestController#httpTest');
The result in browser is
status 200
data JSON_CALLBACK({"username":"Victoria","password":"password","callback":"JSON_CALLBACK"});
httpTesting.js:18 headers function (c){a||(a=sc(b));return
c?a[K(c)]||null:a}
There is chrome extension called postman. You can use to test your back-end url whether it is working or not.

hopefully, my answer will help you.
I try like this:
$http({ method: 'POST', url: '/token', data: { username: $scope.username, password: $scope.password, grant_type: 'password' } }).success(function (data, status, headers, config) {
$scope.output = data;
}).error(function (data, status, headers, config) {
$scope.output = data;
});
then tried changing the grant_type to a param:
$http({ method: 'POST', url: '/token', data: { username: $scope.username, password: $scope.password }, params: { grant_type: 'password' } }).success(function (data, status, headers, config) {
$scope.output = data;
}).error(function (data, status, headers, config) {
$scope.output = data;
});
Still get the dreaded: {"error":"unsupported_grant_type"}
So I do what no AngularJS developer should ever do, resorted to jQuery:
var data = $('#regForm').serialize() + "&grant_type=password";
$.post('/token', data).always(showResponse);
function showResponse(object) {
$scope.output = JSON.stringify(object, null, 4);
$scope.$apply();
};
Which works like a champ... so my question is: how do we replicate the jQuery $.post() call above using AngularJS $http() so we can grab an access token from the OWIN middleware based /token endpoint in ASP.Net Web API 2?
Do this:
$http({
url: '/token',
method: 'POST',
data: "userName=" + $scope.username + "&password=" + $scope.password +
"&grant_type=password"
})
I think, adding the header {headers: { 'Content-Type': 'application/x-www-form-urlencoded' } to your post request would do the trick. It should be something like this:
$http.post(loginAPIUrl, data,
{headers: { 'Content-Type': 'application/x-www-form-urlencoded' }})
You are getting that error because the default implementation of the OWIN OAuth provider is expecting the post to the "/Token" service to be form encoded and not json encoded. There is a more detailed answer here How do you set katana-project to allow token requests in json format?
But you can still use AngularJs you just have to change the way the $http post is made. You can try the answer here if you don't mind using jquery to change your params How can I post data as form data instead of a request payload? Hope that helps.
You can always watch for the requests being made using the developer console in your browser and see the difference in the request.
But by looking at your jquery code &grant_type=password is being passed in the body not the querystring so the $http call should be
$http({ method: 'POST', url: '/token', data: { username: $scope.username, password: $scope.password ,grant_type:password} }).success(function (data, status, headers, config) {
Similar to achinth, but you can still use the $http.post method (+ data is escaped)
$http.post(loginUrl, "userName=" + encodeURIComponent(email) +
"&password=" + encodeURIComponent(password) +
"&grant_type=password"
).success(function (data) {
//...
1) Note the URL: "localhost:55828/token" (not "localhost:55828/API/token")
2) Note the request data. Its not in json format, its just plain data without double quotes.
"userName=xxx#gmail.com&password=Test123$&grant_type=password"
3) Note the content type. Content-Type: 'application/x-www-form-urlencoded' (not Content-Type: 'application/json')
4) When you use javascript to make post request, you may use following:
$http.post("localhost:55828/token",
"userName=" + encodeURIComponent(email) +
"&password=" + encodeURIComponent(password) +
"&grant_type=password",
{headers: { 'Content-Type': 'application/x-www-form-urlencoded' }}
).success(function (data) {//...
See screenshots below from Postman:

Postman Request Header
The following $http request executes successfully, yet the PHP script on the other end receives an empty $_POST array when it should receive 'test' and 'testval.' Any ideas?
$http({
url: 'backend.php',
method: "POST",
data: {'test': 'testval'},
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function (data, status, headers, config) {
console.log(data);
}).error(function (data, status, headers, config) {});
If you wan to send just that simple data, try this:
$http({
url: 'backend.php',
method: "POST",
data: 'test=' + testval,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function (data, status, headers, config) {
console.log(data);
}).error(function (data, status, headers, config) {});
And php part shoul be like this:
<?php
$data = $_POST['test'];
$echo $data;
?>
It is working for me.
This is a common issue with AngularJS.
The first step is to change the default content-type header for POST request:
$http.defaults.headers.post["Content-Type"] =
"application/x-www-form-urlencoded; charset=UTF-8;";
Then, using an XHR request interceptor, it is necessary to serialize properly the payload object:
$httpProvider.interceptors.push(['$q', function($q) {
return {
request: function(config) {
if (config.data && typeof config.data === 'object') {
// Check https://gist.github.com/brunoscopelliti/7492579
// for a possible way to implement the serialize function.
config.data = serialize(config.data);
}
return config || $q.when(config);
}
};
}]);
In this way, payload data will be again available in the $_POST array.
For more info about XHR interceptor.
Another possibility, it is to mantain the default content-type header, and then server side parse the payload:
if(stripos($_SERVER["CONTENT_TYPE"], "application/json") === 0) {
$_POST = json_decode(file_get_contents("php://input"), true);
}
More simplified way:
myApp.config(function($httpProvider) {
$httpProvider.defaults.transformRequest = function(data) {
if (data === undefined) { return data; }
return $.param(data);
};
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';
});
Remove the following line, and the preceding comma:
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
And then the data will appear in $_POST. You only need that line if you are uploading a file, in which case you'll have to decode the body to get the data vars.
I found my solution here http://www.peterbe.com/plog/what-stumped-me-about-angularjs. There is a piece of code in the "AJAX doesn't work like jQuery" section, which solved my problem.
