AngularJS发送异步Get/Post请求方法

作者：袖梨 2022-06-25

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


...

2、添加必要的控件并绑定相应的事件 

 get:{{param}} 

 post:

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 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 




 
 Request



get:

post:

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);
   })
  ;
 }
});
