从AngularJS到Restful web服务的Post请求

我在AngularJS中创建登录页面，提交表单后，数据将发布到Restfull web服务以检查帐户是否存在，如果成功，返回“success”，如果失败，返回“Failed”

网络服务：

@POST
@Path(value = "login")
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
@Produces(MediaType.TEXT_HTML)
public String login(@FormParam("email")String email, @FormParam("pass") String pass){
    UserModel um = new UserModel();
    Nguoichoi nc = um.find(email.trim(), pass.trim());
    if (nc != null){
        return "Success";
    } else { 
        return "Failed";
    }
}

AngularJS函数：

app.controller("LoginController", function($scope,$http) {
        $scope.login = function(){
            var encodeString = "email=" + this.email + "&pass=" + this.pass;
            $http({
                method: "POST",
                url: "http://localhost:8080/HocvuiWebservices/rest/user/login",
                data: encodeString,
                headers: {'Accept':' text/plain', 'Content-Type': "application/x-www-form-urlencoded"}
            }).success(function(data, status, headers, config){
                console.log(data);
            }).error(function(data, status, headers, config){
                console.log(data);
                console.log(status);
                console.log(headers);
                console.log(config);
                console.log("Error submit form");
            });
        }
    });

表格登入：

<form class="login-form" ng-submit="login()">
                <div class="form-group">
                    <label for="exampleInputEmail1">Email: </label> <input
                        type="email" class="form-control" ng-model="email"
                        placeholder="Email">
                </div>
                <div class="form-group">
                    <label for="exampleInputPassword1">Password: </label> <input
                        type="password" class="form-control" ng-model="pass"
                        placeholder="Password">
                </div>
                <div class="form-group">
                    <div class="checkbox">
                        <label> <input type="checkbox"> Remember me
                        </label>
                    </div>
                    <button type="submit" class="btn btn-primary">Loginp</button>
                    &nbsp;&nbsp;&nbsp;<a ui-sref="dangky" class="text-primary">Register</a>
            </form>

但当我提交表单时，post请求返回错误“error submit form”，虽然post请求成功连接到Restful web服务？

您是否可以发布错误日志不应

this.email

和

this.pass

be

$scope.email

和

$scope.pass

？API调用返回什么HTTP状态码？@konko:这是我的控制台。登录错误分支控制台.log（数据）；控制台日志（状态）；console.log（头文件）；console.log（config）；console.log（“错误提交表单”）；=>null UIroute.html:96:6-1函数bd/@Lex:i更改了$scope.email…但出现了相同的错误
