Yii：无法加载 url 页面“错误 404 无法解析请求“用户/用户页面”。”

Question

我是一个 yiibie，我正在尝试从用户表中获取用户数据与那里的 id。为此，我在视图中创建了一个userpage.php 文件，并在user controller 中编写了一个名为Userpage 的函数来从表中获取用户数据。在我写了 url "localhost/projectname/user/userpage?id="anyid" 完成所有这些操作后，它给了我一个错误

Error 404
Unable to resolve the request "user/userpage".

这是我的UserController的代码

Answer 1

检查你有一个正确的视图命名

 userpage.php 

在用户的视图目录中 （用户的相关视图目录取决于您使用的用户组件。）

检查应用程序的命名空间或 config/main.php 以找到正确的目录。

还要检查您是否在用户模型的 accessRules 中正确分配了用户页面。

并且绝对确定您使用的是有效的 $id 值。因为如果在 db 中找不到 id 的值，应该会引发这种消息

并尝试添加 prettyUrl = true 否则你不能使用你的符号

     'urlManager'=>array(
        'urlFormat'=>'path',
        'showScriptName'=>false,
        'enablePrettyUrl' => true,   // Disable r= routes
        'rules'=>array(
    //'<controller:\w+>'=>'<controller>/list',
            '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
            '<controller:\w+>/<id:\d+>/<title>'=>'<controller>/view',
            '<controller:\w+>/<id:\d+>'=>'<controller>/view',
        ),
    ),

Answer 2

您还需要在 public function accessRules() 函数中注册您的 userpage 操作，没有它您将无法从 url 访问此操作。

public function accessRules()
    {
        return array(
            array('allow',  // allow all users to perform 'index' and 'view' actions
                'actions'=>array('index','view'),
                'users'=>array('*'),
            ),
            array('allow', // allow authenticated user to perform 'create' and 'update' actions
                'actions'=>array('create','update','userpage'),
                'users'=>array('@'),
            ),
            array('allow', // allow admin user to perform 'admin' and 'delete' actions
                'actions'=>array('admin','delete'),
                'users'=>array('admin'),
            ),
            array('deny',  // deny all users
                'users'=>array('*'),
            ),
        );
    }

请注意，上述更改将只允许用户使用 userpage 操作，如果您希望它公开，请将其添加到 'users'=>array('*'), 数组
