1、在頁面中加入AngularJS并為頁面綁定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、添加必要的控件并綁定相應的事件
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腳本中發送進行Get/Post請求
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 將參數放在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處理請求并返回結果
get
@RequestMapping("/get") @ResponseBody public Map<String,String> get(String param) { System.out.println("param："+param); response.put("state", "success");//將數據放在Map對象中 return response; }post
@RequestMapping("/post2") @ResponseBody public void post2(@RequestBody User user, HttpServletResponse resp) { //返回不同的http狀態 if(user.getName()!=null&&!user.getName().equals("")){ resp.setStatus(200); } else{ resp.setStatus(300); } }如果需要配置請求頭部
$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請求的回調函數處理并執行下一步操作
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>
