Vue.js实现登录功能

编写html，通过vue-resource.js库向后台提交数据

<!DOCTYPE html>
<html lang="en">
<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 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">登录</h2>-->
            <!-- class="sr-only"将label标签隐藏 -->
            <label for="exampleInputUsername" class="sr-only">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" class="form-control" v-model="formObj.username" id="exampleInputUsername" name="username"
                   placeholder="用户名">
            <label for="exampleInputUsername" class="sr-only">密码</label>
            <input type="password" class="form-control" v-model="formObj.password" id="exampleInputPassword"
                   name="password"
                   placeholder="密码">
           
            <div class="checkbox">
                <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>

后台接收数据

@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 + "";
    }

}
