在localhost上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

我在本地机器上安装了Magento 2.3，安装顺利。我可以在 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网址 http：// localhost / magento / admin_pogi / admin / index / index / key / 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/.

到目前为止我尝试的是启用开发模式，我在我的管理页面上看到此错误：

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

1 exception(s):

推荐答案

这将是一个地址错误这次提交。作者将 $ path 更改为

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

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

这只是调用 realpath（） on $ path 但这可能会改变以前受< $ path 影响的目录分隔符/ p>

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，这将还原以上 str_replace 这样的路径就像

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:\Magento2.3\vendor\magento

这不会导致中的成功比较isPathInDirectories（） 的方法Magento \ Framework \ View \\\\\\\\\\\\\\\\\\\\\ / code> class：

and this will not result in a successful comparison within isPathInDirectories() method of Magento\Framework\View\Element\Template\File\Validator 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 循环中进行一次肮脏的快速更改，以便我们可以运行我们的magento而不会出现进一步的问题：

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;
    }
}
