Tulis html dan serahkan data ke latar belakang melalui perpustakaan vue-resource.js
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>用户注册</title> <link href="bootstrap-4.3.1-dist/css/bootstrap.min.css" rel="stylesheet"> <script src="js/jquery.js"></script> <script src="bootstrap-4.3.1-dist/js/bootstrap.js"></script> <script src="js/vue.js"></script> <!-- 异步提交的库 --> <script src="js/vue-resource.min.js"></script> <style> .container { margin-top: 15%; width: 35%; } .btn-primary { background-color: #337ab7; border-color: #337ab7; } .form-control { margin-bottom: 4px; } </style> </head> <body> <div> <!--<div id="demo" v-show="show" class="alert alert-success"> <span v-if="alert_tips">成功!很好地完成了提交。</span> </div>--> <form id="form"> <div> <!--<h2>登录</h2>--> <!--将label标签隐藏 --> <label for="exampleInputUsername">用户名</label> <!-- 会忽略所有表单元素的value、checked、selected特性的初始值,而总是将Vue实例的数据作为数据来源 --> <input type="text" v-model="formObj.username" id="exampleInputUsername" name="username" placeholder="用户名"> <label for="exampleInputUsername">密码</label> <input type="password" v-model="formObj.password" id="exampleInputPassword" name="password" placeholder="密码"> <div> <label> <!--<input type="checkbox"> 记住密码--> </label> </div> <button class="btn btn-lg btn-primary btn-block" onclick="ajaxRegister()" type="button">注册 </button> </div> </form> </div> </body> <script> function ajaxRegister() { //Vue的异步Get请求 /*Vue.http.get("/test").then(function (res) { console.log(res.bodyText); }, function (res) { console.log(res.status); });*/ var param = new FormData(document.getElementById("form")); // param = convert_FormData_to_json(param); console.log(param); Vue.http.post("/login", param).then(function (res) { console.log(res.bodyText); console.log("登录成功"); }, function (res) { alert("登录失败"); }); return false; } </script> </html>
Menerima data di latar belakang
@RestController public class UserController { @Autowired private UserService userService; //通过RequestBody实现与json交互 @RequestMapping(value = "/register", method = RequestMethod.POST) //接收从客户端传过来的FormData()数据 @RequestMapping(value = "/login", method = RequestMethod.POST) public String login(HttpServletRequest request) throws ParseException { MultipartHttpServletRequest params = (MultipartHttpServletRequest) request; // List<MultipartFile> files = ((MultipartHttpServletRequest) request).getFiles("file"); Map<String, String[]> parameterMap = params.getParameterMap(); //将Map<String,String[]>转成Map对象 Map map = GenUtils.toParameterMap(parameterMap); //将Map对象生成为指定的Pojo对象 User user = GenUtils.mapGetObj(User.class, map); // user = userService.selectByUser(user); // JSONObject jsonObject = JSONObject.fromObject(user); return jsonObject + ""; } }
