- 編寫html，通過vue-resource.js庫向后台提交數據
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>用戶注冊</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> <!-- 異步提交的庫 --> <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 class="container"> <!--<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 class="form-signin"> <!--<h2 class="form-signin-heading">登錄</h2>--> <!-- class="sr-only"將label標簽隱藏 --> <label for="exampleInputUsername" class="sr-only">用戶名</label> <!-- 會忽略所有表單元素的value、checked、selected特性的初始值，而總是將Vue實例的數據作為數據來源 --> <input type="text" class="form-control" v-model="formObj.username" id="exampleInputUsername" name="username" placeholder="用戶名"> <label for="exampleInputUsername" class="sr-only">密碼</label> <input type="password" class="form-control" v-model="formObj.password" id="exampleInputPassword" name="password" placeholder="密碼"> <div class="checkbox"> <label> <!--<input type="checkbox"> 記住密碼--> </label> </div> <button class="btn btn-lg btn-primary btn-block" onclick="ajaxRegister()" type="button">注冊 </button> </div> </form> </div> </body> <script> function ajaxRegister() { //Vue的異步Get請求 /*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("登錄成功"); }, function (res) { alert("登錄失敗"); }); return false; } </script> </html>
- 后台接收數據
@RestController public class UserController { @Autowired private UserService userService; //通過RequestBody實現與json交互 @RequestMapping(value = "/register", method = RequestMethod.POST) //接收從客戶端傳過來的FormData()數據 @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(); //將Map<String,String[]>轉成Map對象 Map map = GenUtils.toParameterMap(parameterMap); //將Map對象生成為指定的Pojo對象 User user = GenUtils.mapGetObj(User.class, map); // user = userService.selectByUser(user); // JSONObject jsonObject = JSONObject.fromObject(user); return jsonObject + ""; } }
