Post data to server angular $http post - javascript

[
{
"name": "AAAAAA",
"date": "28-03-2016",
},
{
"name": "BBBBBB",
"date": "20-12-2016",
},
{
"name": "CCCCCC",
"date": "09-01-2016",
},
{
"name": "DDDDDD",
"date": "21-07-2016",
}
]
My javascript:
var app = angular.module('app', []);
app.service('service', function($http, $q){
var deferred = $q.defer();
$http.get('names.json').then(function(data){
deferred.resolve(data);
});
this.getNames = function() {
return deferred.promise;
}
});
app.controller('FirstCtrl', function($scope, service, $http) {
var promise = service.getNames();
promise.then(function (data) {
$scope.names = data.data;
console.log($scope.names);
}
);
$scope.postfunction = function(data) {
$http({
method: 'POST',
url: 'serwerUrl' ,
data: {"name":$scope.name},
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})
.success(function(data){
console.log('data success');
});
HTML:
<tbody>
<tr ng-repeat="name in names">
<td>{{name.name}}</td>
<td>{{name.date}}</td>
<td><button ng-click="postfunction(names)">POST</button></td>
</tr>
</tbody>
What I want do is when I click the button "POST" name.name post to server. I try function postfunction(), but it didn't post to server, in my console everything is ok, but name.name don't post to server.

The $scope.name you're trying to send isn't defined anywhere.
You'll want to change names here into name:
...
<td><button ng-click="postfunction(name)">POST</button></td>
...
and in your postfunction ditch $scope.name altogether and do this instead (also use .then instead of .success, .success is deprecated):
$scope.postfunction = function(name) {
$http({
method: 'POST',
url: 'serwerUrl' ,
data: {"name": name},
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})
.then(function(data){
console.log('data success');
});
}

Are you sure that the API takes content type application/x-www-form-urlencoded? It is best to use the Angular default of application/json? If you must urlencode the data, use the $httpParamSerializerJQLike Service.
.controller(function($http, $httpParamSerializerJQLike) {
//...
$http({
url: myUrl,
method: 'POST',
data: $httpParamSerializerJQLike(myData),
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
});
});

Angular throwing exception 'module cant be loaded'!

I was trying to clean my angular app code up. So I moved all the controllers in their own files. But when I moved the controllers, my main app stoped working and started throwing the exception below -
Error: $injector:modulerr
Module Error
Then I tried searching for the why the module won't load but with no luck.
main.js /*File where app module is declared*/
var app = angular.module('app', ['ngRoute','thatisuday.dropzone','UserController','LinkController','articleController']);
I tried injecting the dependency for the controller files.

HELP needed!
Yo do not need to declare module in each controller file. Remove the line in each controller
var app = angular.module('app');
You are injecting controller in you module like dependency.
Change your main.js file to this:
var app = angular.module('app', ['ngRoute','thatisuday.dropzone']);
#Sajeetharan is right you do not need module declaration in all controllers.
Since you are using laravel according to your comment. ( It will conflict with your blade template because both use same {{ }} for variables )
There are two ways to do this:
Change the Angular Tags
var app = angular.module('app', [], function($interpolateProvider) {
$interpolateProvider.startSymbol('<%');
$interpolateProvider.endSymbol('%>');
});
Now Laravel will use the {{ variableName }} and Angular will use <%
variableName %>.
Change the Laravel Blade Tags
Blade::setContentTags('<%', '%>');// for variables and all things Blade
Blade::setEscapedContentTags('<%%', '%%>');// for escaped data
Variables will be: <% $variable %>. Comments will be: <%-- $variable
--%>. Escaped data will look like: <%% $variable %%>.
You can check this Tutorial for more info.

Array empty after posting data from angular controler

I am using codeigniter and angular for my app. When I post the data from angular controller to CI controller, array seems to be empty (result of print_r is "array()") .Can someone tell me why?
Angular Part:
$scope.posaljiKontroleru = function () {
$scope.prosek = {kalorije: 0.0, proteini: 0.0, uh: 0.0, masti: 0.0};
$http({
method: 'POST',
url: 'http://localhost/psi/Pravljenjejela/dodajBazi',
data: $scope.prosek
}).then(function (res) {
$window.location.href = "http://localhost/psi/Pravljenjejela/dodajBazi";
}, function (err) {
console.log(err);
});
});
}
CI part
public function dodajBazi() {
$info = $this->input->post();
print_r($info);
}
You need to use default content-type header
Try this:
$http({
method: 'POST',
url: 'http://localhost/psi/Pravljenjejela/dodajBazi',
data: $scope.prosek,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).then(function (res) {
$window.location.href = "http://localhost/psi/Pravljenjejela/dodajBazi";
}, function (err) {
console.log(err);
});

$http not defined when posting to server

Here's my json:
[
{
"name": "AAAAAA",
"date": "28-03-2016",
},
{
"name": "BBBBBB",
"date": "20-12-2016",
},
{
"name": "CCCCCC",
"date": "09-01-2016",
},
{
"name": "DDDDDD",
"date": "21-07-2016",
}
]
My javascript:
var app = angular.module('app', []);
app.service('service', function($http, $q){
var deferred = $q.defer();
$http.get('names.json').then(function(data){
deferred.resolve(data);
});
this.getNames = function() {
return deferred.promise;
}
});
app.controller('FirstCtrl', function($scope, service) {
var promise = service.getNames();
promise.then(function (data) {
$scope.names = data.data;
console.log($scope.names);
}
);
$scope.postfunction = function() {
$http({
method: 'POST',
url: 'serverUrl',
data: name.name,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})
};
});
My HTML:
<tbody>
<tr ng-repeat="name in names">
<td>{{name.name}}</td>
<td>{{name.time | date}}</td>
<td><button ng-click="postfunction()">POST</button></td>
</tr>
</tbody>
What I want do is when I click the button "POST" name.name post to server. I try $http.post in postfunction(), but I get "$http is not defined" in console.
You forgot to inject $http into your controller
app.controller('FirstCtrl', function($scope, service, $http) {
^
You have to inject $http service in your controller 'FirstCtrl' as below:
app.controller('FirstCtrl', function($scope, service, $http) {
var promise = service.getNames();
promise.then(function (data) {
$scope.names = data.data;
console.log($scope.names);
}
);
$scope.postfunction = function(name) {
$http({
method: 'POST',
url: 'serverUrl',
data: name,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})
};
});
Also additionally along with passing the argument to the post function, you have to pass the 'name' in the HTML as below, this is because, in your controller, 'name' is never defined.
<tbody>
<tr ng-repeat="name in names">
<td>{{name.name}}</td>
<td>{{name.time | date}}</td>
<td><button ng-click="postfunction(name.name)">POST</button></td>
</tr>
</tbody>

How to return transformed data from a $http.json request in angular?

How can I return the APIData.map and not the default success APIdata using $http.jsonp?
LangDataService Constructor:
languages.LangDataService = function($http, $q) {
this.langDefer = $q.defer();
this.isDataReady = this.langDefer.promise;
};
languages.LangDataService.prototype.getApi = function() {
return this.isDataReady = this.http_.jsonp(URL, {
params: {}
})
.success(function(APIData) {
return APIData.map(function(item){
return item + 1; //just an example.
});
});
};
A Ctrl using LandDataService:
languages.LanguageCtrl = function(langDataService) {
languages.langDataService.isDataReady.then(function(data){
console.log('whooo im a transformed dataset', data);
});
}
Use then instead of success in getApi function.
Try a version of the following:
https://jsfiddle.net/L2ndft4w/
// define the module for our AngularJS application
var app = angular.module('App', []);
app.factory('LangDataService', function($q,$http) {
return {
getApi: function() {
var defer= $q.defer();
$http({
url: 'https://mysafeinfo.com/api/data?list=zodiac&format=json&alias=nm=name',
dataType: 'json',
method: 'GET',
data: '',
headers: {
"Content-Type": "application/json"
}
}).
success(function (data) {
defer.resolve(data.map(function(item){
return item.name;
}));
})
return defer.promise;
}
};
});
// invoke controller and retrieve data from $http service
app.controller('DataController', function ($scope, LangDataService) {
LangDataService.getApi().then(function(data){
$scope.data = JSON.stringify(data, null, 2);
});
});
Returns:
[
"Aquarius",
"Aries",
"Cancer",
"Capricorn",
"Gemini",
"Leo",
"Libra",
"Ophiuchus",
"Pisces",
"Sagittarius",
"Scorpio",
"Taurus",
"Virgo"
]
Although, since $http is already a promise, there's probably a shorter way to do this... ($q.when?)

Angularjs Ajax get sending headers

I'm new to angularjs, and im using a service for my http requests.
one of the rest api's i need to send key value pairs in the header.
username: foo
password: bar
how do i do it using the http request format i have in my service. (i'm aware i need to pass an argument in the function i don't how to go about it and what object format)
.service('UserService', ['$http', '$rootScope', function ($http, $rootScope) {
this.CheckIfUserExists = function () {
return $http.get($rootScope.endPoint + '/user/email_token');
};
}
...
//in the controller
UserService.CheckIfUserExist()
.success(function (data) {
console.log(data);
//handler
}).
error(function(error) {
//handler
});
Example from the doc
you need know what kind of auth. you can use post for example.
.service('UserService', ['$http', '$rootScope', function ($http, $rootScope) {
var req = {
method: 'POST',
url: 'http://example.com',
headers: {
'Content-Type': undefined
},
data: { test: 'test' }
}
$http(req).success(function(){...}).error(function(){...});
In your case:
.service('UserService', ['$http', '$rootScope', function ($http, $rootScope) {
this.CheckIfUserExists = function () {
var req = {
method: 'POST',
url: 'http://example.com'
data: { 'username': 'foo', 'password': 'bar' }
};
return $http(req);
}
}
