Question

我正在尝试在nginx中设置自定义标头，最后将其传递给运行django应用程序的gunicorn服务器。更改nginx配置文件后，我检查了django中的request.META字典，但我的自定义标头丢失了。我相信nginx没有正确发送标头。这是我相关的nginx配置文件内容。

server {
   listen 443;
   server_name www.example.com;
   client_max_body_size 40M;
   ssl on;
   ssl_certificate /home/ubuntu/prodStuff/ssl/server.crt;
   ssl_certificate_key /home/ubuntu/prodStuff/ssl/server.key;

   ssl_session_timeout 5m;
   ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
   ssl_ciphers "HIGH:!aNULL:!MD5 or HIGH:!aNULL:!MD5:!3DES";
   ssl_prefer_server_ciphers on;

    access_log /home/ubuntu/logs/nginx-access.log;
    error_log /home/ubuntu/logs/nginx-error.log info;
    set $mobile_rewrite perform;
     location / {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_redirect off;
            if ($mobile_rewrite = perform) {
              proxy_set_header renderMobileWebsite "1";
            }
            else{
              proxy_set_header renderMobileWebsite "0";
            }
            proxy_pass_header renderMobileWebsite;
            if (!-f $request_filename) {
            proxy_pass http://djangoapp_server;
            break;
            }
    }

然后我只打印request.META但没有renderMobileWebsite标头的条目。这是打印请求的输出.META

有谁能告诉我这里我做错了什么。

主要问题是proxy_set_header块中不允许if指令。

但是，使用map指令可以实现相同的功能。在http块中使用以下内容：

map $mobile_rewrite $render_mobile_rewrite {
    default     0;
    perform     1;
}

现有位置区块中的以下内容：

proxy_set_header renderMobileWebsite $render_mobile_rewrite;
