本地主机中 Magento 2.3.0 CE 上的空白管理页面 [英] Blank admin page on Magento 2.3.0 CE in localhost

问题描述

我已经在本地机器上安装了 Magento 2.3，安装顺利.我可以通过 localhost/magento 访问我的商店.我试图访问我的管理页面 localhost/magento/admin_pogi 但它给了我一个空白页面并重定向到 url http://localhost/magento/admin_pogi/admin/index/index/密钥/a062e79f617010c42b07d662103d5142cd9bbe86314fb54da3e4cb5542b11eee/.

I have installed Magento 2.3 on my local-machine, installation goes fine. I can access my store at localhost/magento. I tried to access my admin page localhost/magento/admin_pogi but it gives me a blank page and redirected to the url http://localhost/magento/admin_pogi/admin/index/index/key/a062e79f617010c42b07d662103d5142cd9bbe86314fb54da3e4cb5542b11eee/.

到目前为止我尝试过的是启用开发模式，我在我的管理页面上看到了这个错误:

What I have tried so far is to enable development mode, and I see this error on my admin page:

推荐答案

这将是一个错误，解决了 此提交.作者将 $path 更改为

This would be a bug that addresses this commit. Author changed $path to

$this->fileDriver->getRealPath($path)

它只是在 $path 上调用 realpath() 但这可能会改变 $path 上以前受

which is simply calling realpath() on $path but that might change directory separators on the $path that previously were affected by

#/vendor/magento/framework/View/Element/Template/File/Validator.php:114
$filename = str_replace('\', '/', $filename);

在 Windows 操作系统上，这将恢复上述 str_replace 的更改，以便像

On a Windows OS this will revert changes of above str_replace so that a path like

D:/Magento2.3/vendor/magento

将被规范化为其特定于 Windows 的版本:

will be canonicalized to its Windows specific version:

D:Magento2.3vendormagento

并且这不会在 MagentoFrameworkViewElementTemplateFileValidator 类的 isPathInDirectories() 方法中导致成功的比较:

and this will not result in a successful comparison within isPathInDirectories() method of MagentoFrameworkViewElementTemplateFileValidator class:

foreach ($directories as $directory) {
    if (0 === strpos($realPath, $directory)) {
        return true;
    }
}

解决方案

目前，我们可以在上面的 foreach 循环中进行肮脏的快速更改，以便我们可以运行我们的 magento 而不会出现更多问题:

Solution

Currently we can go for a dirty quick change in the above foreach loop so that we can run our magento with no further problems on this:

#/vendor/magento/framework/View/Element/Template/File/Validator.php:139
foreach ($directories as $directory) {
    // Add this line
    $realDirectory = $this->fileDriver->getRealPath($directory);
    // and replace `$directory` with `$realDirectory`
    if (0 === strpos($realPath, $realDirectory)) {
        return true;
    }
}
