我是yiibie，我正在尝试从用户表中获取用户数据。为此，我在视图中创建了一个userpage.php文件，并在名为user controller的{{1}}中编写了一个函数，以从表中获取用户数据。在完成所有这些操作后，当我写下网址Userpage时，它会给我一个错误
"localhost/projectname/user/userpage?id="anyid"这是我的Error 404
Unable to resolve the request "user/userpage".
UserController这是我的视图文件（userpage.php）的代码

检查您是否有一个名为
的正确视图 userpage.php
在用户的view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，找到合适的目录。
同时检查您是否在User模型的accessRules中正确分配了用户页面。
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的值应该引发这种消息
并尝试添加prettyUrl = true，否则您无法使用您的符号
'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',
),
),

您还需要在userpage功能中注册public function accessRules()操作，如果没有该操作，则无法通过网址访问此操作。
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，上述更改只允许用户使用userpage操作，如果您希望将其公开添加到'users'=>array('*'),数组
