AngularJS发送异步Get/Post请求方法

1、在页面中加入angularjs并为页面绑定ng-app 和 ng-controller

1、在页面中加入angularjs并为页面绑定ng-app 和 ng-controller

<body ng-app="myapp" ng-controller="myctrl" >
...
<script src="js/angular.min.js"></script>
<script src="js/sbt.js"></script>

2、添加必要的控件并绑定相应的事件

 get:<input type="text" ng-model="param">{{param}} <br>
 post: <input type="text" ng-model="user.name"><input type="text" ng-model="user.password"><br>
 <button ng-click="get()">get</button>
 <button ng-click="post()">post</button>

3、在js脚本中发送进行get/post请求

get

$scope.get = function () {
  $http.get("/get", {params: {param: $scope.param}})
   .success(function (data, header, config, status) {
    console.log(data);
   })
   .error(function (data, header, config, status) {
    console.log(data);
   })
  ;
 }

get 将参数放在url中

$scope.get = function () {
  $http.get("/get?param="+$scope.param)
   .success(function (data, header, config, status) {
    console.log(data);
   })
   .error(function (data, header, config, status) {
    console.log(data);
   })
  ;
 }

post

$scope.post = function () {
  $http.post("/post", $scope.user)
   .success(function (data, header, config, status) {
    console.log(data);
   })
   .error(function (data, header, config, status) {
    console.log(data);
   })
  ;
 }

4、由controller处理请求并返回结果

get

@requestmapping("/get")
 @responsebody
 public map<string,string> get(string param) {
  system.out.println("param:"+param);
  response.put("state", "success");//将数据放在map对象中
  return response;
 }

post

 @requestmapping("/post2")
 @responsebody
 public void post2(@requestbody user user, httpservletresponse resp) {
  //返回不同的http状态
  if(user.getname()!=null&&!user.getname().equals("")){
   resp.setstatus(200);
  }
  else{
   resp.setstatus(300);
  }
 }

如果需要配置请求头部

  $http({
   method : "post",
   url : "/post",
   data : $scope.user
  }).success(function(data, header, config, status) {
   console.log(data);
  }).error(function(data, header, config, status) {
   console.log(data);
  });

5、由js http请求的回调函数处理并执行下一步操作

html

<!doctype html>
<html lang="en">
<head>
 <meta charset="utf-8">
 <title>request</title>
</head>

<body ng-app="myapp" ng-controller="myctrl" >
get:<input type="text" ng-model="param"><br>
post: <input type="text" ng-model="user.name"><input type="text" ng-model="user.password"><br>
 <button ng-click="get()">get</button>
 <button ng-click="post()">post</button>
</body>
<script src="js/angular.min.js"></script>
<script src="js/sbt.js"></script>
</html>

sbt.js

var app = angular.module("myapp", []);
app.controller("myctrl", function ($scope, $http) {

 $scope.get = function () {
  $http.get("/get", {params: {param: $scope.param}})
   .success(function (data, header, config, status) {
    console.log(data);
   })
   .error(function (response) {
    console.log(response);
   })
  ;
 }

 $scope.post = function () {
  $http.post("/post", $scope.user)
   .success(function (data, header, config, status) {
    console.log(data);
   })
   .error(function (data, header, config, status) {
    console.log(data);
   })
  ;
 }
});
