Summary
When Angularjs sends a POST request, it is really confusing, when passing JSON data, always encountered in the server can not accept parameters, it is necessary to compare with $.post to learn.
An example
Here to simulate a scene of login, post user name and password, the server accepts the account and returns directly to the client without doing other business processing.
Using the ANGULARJS version
/* AngularJS v1.2.15 (c) 2010-2014 Google, Inc. http://angularjs.org license:mit */
Service side
Public classAccountcontroller:controller {//GET:/<controller>/ PublicIactionresult Login () {returnView (); } [HttpPost] PublicIactionresult Login (stringUserName,stringuserpwd) { varResut =Request.Form; returnJson (New{_code = $, _msg ="Login Success", name = userName, password =userpwd}); } }
$.post
First use $.post to submit your account password directly
$.post ("@Url. Content ("~/account/login")"" 2342342", Userpwd:"2sssdfs" },function (data) { Console.log (data); });
Response
Here we look at the request body
So now we look at the situation of Angularjs's $http.post, what is the difference?
@{Layout = null;}<!DOCTYPE HTML><HTMLNg-app= "Login"><Head> <Metaname= "Viewport"content= "Width=device-width, initial-scale=1.0" /> <title>It strange o user Login</title> <Linkhref= "~/lib/bootstrap/dist/css/bootstrap.css"rel= "stylesheet" /> <Scriptsrc= "~/js/angular.min.js"></Script> <Script>Angular.module ("Login", []). Controller ("Logincontroller", function($http, $scope) {$scope. Login= function () { varData={userName: $scope. UserName, Userpwd: $scope. userpwd}; varConfig={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 ("&"); //} }; Console.log (data); $http. Post ("@Url. Content ("~/ Account/Login")", data, config). Success (function(data) {Console.log (data); }); }; }); </Script></Head><Body> <DivNg-controller= "Logincontroller"> <inputtype= "text"placeholder= "User name"Ng-model= "UserName"value="" /> <inputtype= "Password"placeholder= "Password"Ng-model= "Userpwd"value="" /> <ButtonNg-click= "Login ()">Login</Button> </Div></Body></HTML>
Login
Appeared, in the habit of reason, usually will write $http.post. But the result is not what you want. So let's compare the request body with $.post.
Did you see that? The difference is right here.
When we find the problem, we are going to convert it into the way $.post submits the parameters. Fortunately, Angularjs $http.post provides a transformrequest method for conversion parameters that can be added to config:
var config = { 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 ("&"); } ;
Its role is to convert the submitted parameters into $.post submission parameters. In this case, the parameters in the request body are identical to the $.post.
can be set globally
<script>Angular.module ("Login", []). Controller ("Logincontroller",function($http, $scope) {$scope. Login=function () { vardata ={userName: $scope. UserName, Userpwd: $scope. userpwd}; Console.log (data); $http. Post ("@Url. Content (" ~/account/login ")", data). Success (function(data) {Console.log (data); }); }; }). config (function($httpProvider) {$httpProvider. defaults.transformrequest=function(obj) {varstr = []; for(varPinchobj) {Str.push (encodeURIComponent (p)+ "=" +encodeURIComponent (obj[p])); } returnStr.join ("&"); }; $httpProvider. defaults.headers.post[' Content-type '] = ' application/x-www-form-urlencoded; Charset=utf-8 '; }); </script>
Summarize
Angularjs the configuration of the parameters when making the POST request. With regard to the post request of Angularjs, it is recommended to set the request header and request parameter conversion settings for the POST request when initializing the module, which can be easily used elsewhere.
