Question

我已经创建了登录表单。我想在成功登录后在导航栏上显示配置文件菜单项。我在控制器内使用http服务将数据发布到数据库，以验证用于登录的电子邮件和密码组合。未使用的服务或工厂。我使用ui_router进行导航。

我的导航栏页面是

<!-- Navigation -->
<nav class="navbar navbar-inverse" role="navigation">
  <div class="container">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
      <a class="navbar-brand" ui-sref="home"> <img src="images/logo.png" /></a>
    </div>
    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav navbar-right">
        <li ui-sref-active="active"><a ui-sref="home">HOME</a></li>
        <li ui-sref-active="active"><a ui-sref="register">REGISTER</a></li>
        <li ui-sref-active="active"><a ui-sref="login">SIGN IN</a></li>
        <li ui-sref-active="active"><a ui-sref="contact">CONTACT</a></li>
      </ul>
    </div>
    <!-- /.navbar-collapse -->
  </div>
  <!-- /.container -->
</nav>

我的登录页面是

<div class="col-lg-6 col-lg-offset-3 well " style="margin-top:1em; background-color:black; ">

  <h4 style="color:white; text-align:center;"> <strong> LOGIN  </strong> </h4>

</div>


<div class="col-lg-6 col-lg-offset-3 well" style="margin-bottom:13em;">

  <form name="login" ng-app="TempleWebApp" ng-controller="logCtrl" ng-submit="signin(login.$valid)" novalidate>

    <div class="form-group col-lg-12" ng-class="{ 'has-error' : login.email.$invalid && (login.email.$dirty || submitted)}">
      <label>Email</label>
      <input class="form-control" type="text" name="email" ng-model="useremail" placeholder="Email" ng-pattern="/^[^\s@]+@[^\s@]+\.[^\s@]{2,}$/" ng-required="true">

      <span class="help-block" ng-show="login.email.$error.pattern">

    </div>


    <div class="form-group col-lg-12" ng-class="{ 'has-error' : login.password.$invalid && (login.password.$dirty || submitted)}">
      <label>Password</label>
      <input class="form-control" type="password" name="password" ng-model="userpassword" placeholder="Password" ng-required="true">
      <span class="help-block" ng-show="login.password.$invalid && login.password.$error.required && (login.password.$dirty || submitted)">
				          Password is required.</span>
    </div>

    <div class="col-lg-12 well " ng-repeat="error in errors" style="background-color:red; margin-top:0.5em;"> {{ error}} </div>
    <div class="col-lg-12 well" ng-repeat="msg in msgs" style="margin-top:0.5em;">
      <h5 style="color:green;">{{ msg}} </h5>
    </div>


    <button type="submit" class="btn btn-success col-lg-12"> 
				   <span ng-show="searchButtonText == 'REDIRECTING TO PROFILE PAGE'"><i class="glyphicon glyphicon-refresh spinning"></i></span>
                  {{ searchButtonText }}
				</button>


  </form>
</div>

我的js文件是

Answer 1

登录成功后，您可以将令牌设置为cookie，并在主页中检查cookie中是否存在令牌并显示导航项。

Answer 2

    public interface APIService {
      @GET("{path}/following/{target}")
      Call<Users> getFollowers(@Path("path") String path,@Path("{target}") String target) );
    }

成功登录后如何显示菜单项？
