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);   })  ; }});
