为什么 nginx 内部重定向没有发生

我很确定我错过了一个显而易见的事情但这让我发疯，我需要其他的眼球......

我得到了一个带有插件的应用程序，其源的组织方式如下：

/app/plugins/foo/www/... 对应于我的 URLhttp://example.com/plugins/foo/...

我得到以下代码片段作为 nginx 配置：

location /plugins/foo {
    alias /app/plugins/foo/www;
    try_files $uri /index.php =404;
}

location ~* ^/plugins/foo/(.*\.php)$ {
    alias /app/plugins/foo/www/$1;

    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

它适用于以下 URL：

但是当我尝试到达（前端控制器模式）时：

我必须下载 php 文件。

根据日志，try_files 似乎执行了预期的操作，但它没有将内部重定向到 php 处理程序，而是将文件作为静态服务器：

所以问题是：在这种情况下如何实现我的前端控制器模式？

编辑

和

location /plugins/foo {
    alias /app/plugins/foo/www;
    try_files $uri /plugins/foo/index.php?$args;
}

我被重定向到核心前端控制器而不是插件控制器：

2017/01/25 13:45:48 [debug] 14086#0: *197 using configuration "/plugins/foo"
...
2017/01/25 13:45:48 [debug] 14086#0: *197 try files phase: 12
2017/01/25 13:45:48 [debug] 14086#0: *197 http script var: "/plugins/foo/"
2017/01/25 13:45:48 [debug] 14086#0: *197 trying to use file: "/" "/app/plugins/foo/www/"
2017/01/25 13:45:48 [debug] 14086#0: *197 http script copy: "/plugins/git/index.php?"
2017/01/25 13:45:48 [debug] 14086#0: *197 http script var: "group_id=101"
2017/01/25 13:45:48 [debug] 14086#0: *197 trying to use file: "/index.php?group_id=101" "/app/plugins/foo/www/index.php?group_id=101"
====> ??? 2017/01/25 13:45:48 [debug] 14086#0: *197 internal redirect: "/index.php?group_id=101"
2017/01/25 13:45:48 [debug] 14086#0: *197 rewrite phase: 1
...

为什么重定向到/index.php?group_id=101何时/app/plugins/foo/www/index.php?group_id=101有效？

为了避免长期存在的问题alias和一起使用try_files，你可以使用if块来代替（注意注意使用限制）。另请注意，$request_filename使用 而不是 来$document_root$fastcgi_script_name获取别名路径名。

我已经测试过这个例子：

location ^~ /plugins/foo {
    alias /app/plugins/foo/www;

    if (!-e $request_filename) {
        rewrite ^ /plugins/foo/index.php last;
    }

    location ~ \.php$ {
        if (!-f $request_filename) {
            rewrite ^ /plugins/foo/index.php last;
        }
        fastcgi_pass 127.0.0.1:9000;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $request_filename;
    }
}
  • 修改^~器使此location块优先于location同一级别的其他块（参见这个文件）。
  • 该rewrite语句会自动附加参数（参见这个文件）。
  • 嵌套location块处理别名范围内的 PHP 文件。
  • 总是include fastcgi_params; 前用来fastcgi_param避免后者被包含的文件悄悄覆盖。
