用nginx部署django站点时的错误

用nginx部署django站点时的错误

站点用flup做代理，nginx配置部分如下：

location / {
    proxy_connect_timeout    60;
    proxy_read_timeout       60;
    proxy_send_timeout       60;

    include fastcgi_params;
    fastcgi_read_timeout 60;
    fastcgi_pass 127.0.0.1:6000;
    fastcgi_param PATH_INFO $fastcgi_script_name;
}

对于django来说，必须用到PATH_INFO，所以加了fastcgi_param PATH_INFO $fastcgi_script_name;。然后问题也来了，所有url都无法找到。通过django的日志发现，所有url都重复了，比如/api变成了/api/api/。

原来问题在于 fastcgi_params的内容

nginx的/etc/nginx/fastcgi_params文件内容是这样的：

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;`

其中，fastcgi_param SCRIPT_NAME $fastcgi_script_name;和fastcgi_param PATH_INFO $fastcgi_script_name;的作用相当于request.path = SCRIPT_NAME/PATH_INFO/，导致了url重复的现象。
