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);
})
;
}
});
