在使用mod_proxy_fcgi时重写URL,PATH_INFO以404错误结束

我在Apache 2.4.25上有一个虚拟主机,通过mod_proxy_fcgi连接PHP-FPM 7.1.4,如下所示:

<VirtualHost *:80> ServerName example.com DocumentRoot /srv/www/example.com <Directory /srv/www/example.com> AllowOverride All Require all granted </Directory> SetEnvIfNoCase ^Authorization$ "(.+)" HTTP_AUTHORIZATION=$1 <FilesMatch ".+\.ph(p[3457]?|t|tml)$"> SetHandler "proxy:unix:/run/php/example.sock|fcgi://localhost" </FilesMatch> </VirtualHost> 

大多数应用程序在这个设置上都能正常工作,但是有一个应用程序使用PATH_INFO来提取请求。 该应用程序在它的.htaccess中有这样的东西:

 RewriteEngine On RewriteCond $1 ^index\.php RewriteRule ^(.*)$ - [PT,L] RewriteRule ^(.*)$ index.php/$1 [PT,L] 

简而言之,所有不是index.php东西都应该作为一个path传递给它。 访问URL http://example.com/index.php/test工程并按预期显示[PATH_INFO] => /test ,但访问http://example.com/test与

 AH01071: Got error 'Primary script unknown\n' 

为mod_rewrite和mod_proxy_fcgi设置LogLevel trace6表明redirect已正确完成,正确的path也被传递给PHP-FPM。

跟踪/index.php/test:

如何让Apache正确地重写URL并同时传递PATH_INFO?

注意:这个问题可能类似于Apache 2.4 + PHP-FPM + ProxyPassMatch,但在我的情况下,我已经使用了SetHandler 。 问题出在PATH_INFO部分,那里的答案似乎没有解决。

经过几天的努力,我已经捕获并检查了在Apache和PHP-FPM之间发送的CGI头文件,并且也对不同版本的组件进行了相同的testing。 事实certificate,Apache的不同版本设置SCRIPT_FILENAMEvariables的方式不同,这在PHP-FPM中是不被考虑的。
Apache 2.4.18(在我使用的Ubuntu 16.04中是默认的)填充variables,如下所示:

 SCRIPT_FILENAME proxy:fcgi://localhost/srv/www/index.php 

鉴于Apache 2.4.25套装:

 SCRIPT_FILENAME /srv/www/index.php 

mod_proxy_fcgi的Apache文档中提到了自Apache 2.4.26以来的一个指令ProxyFCGIBackendType (尚未发布到2017-05-02),默认为“FPM”。 说明中有以下说明:

根据此指令的设置更改值的一个示例是SCRIPT_FILENAME。 在历史上使用mod_proxy_fcgi时,SCRIPT_FILENAME前缀为string“proxy:fcgi://”。 这个variables是一些通用的FastCGI应用程序将读取的脚本input,但是PHP-FPM将去掉前缀,然后记住它正在与Apache交谈。 在2.4.21到2.4.25中,这个前缀被服务器自动剥离,在一些场景中打破了PHP-FPM检测和与Apache交互的能力。

似乎我巧合地发现“一些情况”。 回答我自己的问题是: 不要使用Apache 2.4.21到2.4.25,因为它们包含一个错误。 使用较低版本或等待较新的地方修正了错误。
