Yii2 错误:视图文件不存在 [英] Yii2 error: The view file does not exist
问题描述
我已经使用 Yii2 几个星期了，并且已经掌握了它的窍门.然而，今天，不知为何，Yii 一直把我路由到错误的页面，导致错误，因为没有找到网页:
I've been using Yii2 for a few weeks now, and getting the hang of it. However, today, for a reason I do not know, Yii's been routing me to the wrong page, causing errors because web pages have not been found:
URL:
http://localhost/web/index.php?r=site/index
Error:
Invalid Parameter – yii\base\InvalidParamException
The view file does not exist: C:\xampp\htdocs\views\site\index.php
但是，自从我开始使用 Yii2 以来，我已经能够使用 http://localhost/web/index.php?r=paramA/paramB 浏览我的网站，但我还没有编辑配置文件已经有一段时间了，所以我不知道为什么会发生这种情况.
However, I've been able to navigate my site with http://localhost/web/index.php?r=paramA/paramB since I started using Yii2, and I haven't been editing configuration files for quite some time, so I don't know why this started happening.
一些可能有用的文件:
/web/index.php(几乎没有编辑):
<?php
require_once __DIR__.'/../util/Tools.php';
// comment out the following two lines when deployed to production
defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');
require(__DIR__ . '/../vendor/autoload.php');
require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php');
$config = require(__DIR__ . '/../config/web.php');
(new yii\web\Application($config))->run();
controllers/SiteController.php 的一部分:
public function actions()
{
return [
'error' => [
'class' => 'yii\web\ErrorAction',
],
...
];
}
public function actionIndex()
{
return $this->render('index');
}
此外，在 config/web.php 中我没有 urlManager 组件.
Also, in config/web.php I have no urlManager component.
为什么会发生这种情况，我能做些什么?另外，由于我不知道在哪里搜索，我可能没有发布正确的代码进行分析，但我当然可以必要时添加代码.
Why is this happening and what can I do against it? Also, since I do not know where to search, I probably haven't posted the correct code to analyze, but of course I can add code when necessary.
此外，当我开始抛出一些UserExceptions(显示一些无效的发布请求等)时，它就开始了.这立即显示了 /views/site/error.php 不存在的错误.我创建了那个 php 文件，但随后出现了上述问题.我删除了 /views/site/error.php 文件，但问题仍然存在.
Moreover, it started when I started throwing some UserExceptions (To show some invalid post requests and such). That instantly showed an error that /views/site/error.php did not exist. I created that php file, but then the problem described above occurred. I removed the /views/site/error.php file, but the problem persists.
我猜这与 url 重写有关，但是在将 urlManager 组件添加到 /config/web.php 后没有任何反应(我尝试后将其删除)
I guess it has something to do with url rewriting, but nothing happened after adding an urlManager component to /config/web.php (which I removed after trying)
另外，在 \vendor\yiisoft\yii2\base\View.php 中有这样的代码:
Also, in \vendor\yiisoft\yii2\base\View.php there's this code:
public function render($view, $params = [], $context = null)
{
$viewFile = $this->findViewFile($view, $context);
return $this->renderFile($viewFile, $params, $context);
}
$viewFile 返回找不到的路径(views\site\index.php).
And $viewFile returns the path which can't be found (views\site\index.php).
此外，在 SiteController.php 中，$this->viewPath 是 C:\xampp\htdocs\views\site(其中它不应该......?)
Also, in SiteController.php, $this->viewPath is C:\xampp\htdocs\views\site (which it shouldn't..?)

推荐答案
所以，默认情况下，当你在 site 控制器中调用 render('index') 时，Yii 将在文件夹 web/views/site 中查找名为 index.php 的文件.这包含您的 site/index 视图文件.它应该在您创建站点时就在那里，但如果您还没有得到它，那么它一定是在某个阶段被删除了.创建文件并放入您的视图代码，您应该就可以开始了.
So, by default, when you call render('index') in the site controller, Yii will look in the folder web/views/site for a file called index.php. This contains your site/index view file. It should have been there when you created the site, but if you haven't got it then it must have been deleted at some stage. Create the file and put in your view code, and you should be good to go.
