nginx:将单个静态 URL 映射到 PHP 文件

Question

我有一个 WordPress 安装启动并运行，没有问题。页面上有一个元素不是 WP 的一部分，而是我们自己的自定义 PHP 脚本。它只是在那里处理表单 POST 请求并以某种方式处理它。

要求我们没有以 .php 结尾的扩展名。我的表单提交给类似的东西:

/places/signup.html

在我的 nginx 配置中，我有这个:

server {
    listen       87948; # It's behind a reverse proxy
    server_name domain.com www.domain.com;

    include /etc/nginx/proxy_params;

    index index.php;
    root /opt/www/public_html;

    location /favicon.ico {
        return 404;
    }

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        expires max;
        log_not_found off;
    }

    location ~ \.php$ {
        add_header Access-Control-Allow-Origin "*";
        client_body_buffer_size 4096k;
        fastcgi_pass unix:/tmp/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /opt/www/public_html/$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_script_name;
        include /etc/nginx/fastcgi_params;
    }

    # LOOK HERE
    location ~ /places/signup.html {
        root                             /opt/www/custom_scripts/;
        fastcgi_pass    unix:/tmp/php5-fpm.sock;
        fastcgi_param   SCRIPT_FILENAME  /opt/www/custom_scripts/signup-processor.php;
        fastcgi_param   QUERY_STRING     $query_string;
        fastcgi_param   REQUEST_METHOD   $request_method;
        fastcgi_param   CONTENT_TYPE     $content_type;
        fastcgi_param   CONTENT_LENGTH   $content_length;
        include         fastcgi_params;
    }

}

问题是:fastcgi 或 nginx(我不知道哪个)正在获取文字 URL 并在 location 块的 root 指令中查找它。从错误日志:

2013/01/16 15:30:42 [error] 20533#0: *4 FastCGI sent in stderr: "Unable to open primary script: /opt/www/custom_scripts/places/signup.html (No such file or directory)" while reading response header from upstream, client: 66.172.31.153, server: domain.com, request: "POST /places/signup.html HTTP/1.1", upstream: "fastcgi://unix:/tmp/php5-fpm.sock:", host: "www.domain.com"

我想“fastcgi_param SCRIPT_FILENAME/opt/www/custom_scripts/signup-processor.php;”会强制它使用那个特定的脚本吗？我猜不是？

Answer 1

include最后的指令:

    include         fastcgi_params;

可能还有另一个 fastcgi_param带有 SCRIPT_FILENAME 的指令范围 :

    fastcgi_param   SCRIPT_FILENAME  /another/script/file/name;

由于它位于文件末尾，因此它将覆盖您的值。

如果你想从你的 fastcgi_params 文件中保留一些设置，但用特定的来覆盖它们，你应该放置 include开头的指令:

location ~ /places/signup.html {
    include         fastcgi_params;
    root                             /opt/www/custom_scripts/;
    fastcgi_pass    unix:/tmp/php5-fpm.sock;
    fastcgi_param   SCRIPT_FILENAME  /opt/www/custom_scripts/signup-processor.php;
    fastcgi_param   QUERY_STRING     $query_string;
    fastcgi_param   REQUEST_METHOD   $request_method;
    fastcgi_param   CONTENT_TYPE     $content_type;
    fastcgi_param   CONTENT_LENGTH   $content_length;
}
