UWSGI没有从nginx服务器接收自定义标头

Question

目标是让nginx服务器将名为X-PA-AUTH_TOKEN的自定义请求标头传递给uwsgi服务器。下面是server文件中的nginx.conf块。

server {
    listen       9390 default_server;
    server_name  _;

    location / {
        include uwsgi_params;
            uwsgi_pass_request_headers      on;
            uwsgi_pass unix:/run/uwsgi/irm.sock;
            uwsgi_pass_header X-PA-AUTH_TOKEN;

        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            #
            # Custom headers and headers various browsers *should* be OK with but aren't
            #
            add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,X-PA-AUTH_TOKEN';
            #
            # Tell client that this pre-flight info is valid for 20 days
            #
            add_header 'Access-Control-Max-Age' 1728000;
            add_header 'Content-Type' 'text/plain; charset=utf-8';
            add_header 'Content-Length' 0;
            add_header 'X-PA-AUTH_TOKEN' '0';
            return 204;
         }
         if ($request_method = 'POST') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,X-PA-AUTH_TOKEN';
            add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range,X-PA-AUTH_TOKEN';
         }
         if ($request_method = 'GET') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,X-PA-AUTH_TOKEN';
            add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range,X-PA-AUTH_TOKEN';
         }
    }
}

uwsgi服务器从nginx服务器接收传统的标题，如'Content-Type'。

但是，uwsgi服务器仍然没有从X-PA-AUTH_TOKEN服务器接收自定义请求头nginx，例如，发出POST请求。

我在这做错了什么？

我相信默认情况下，nginx标记带有下划线（X-PA-AUTH_TOKEN）的标头无效，因此它们会被阻止。您可以在nginx配置（underscores_in_headers: on;）中启用docs here，或者只是将标题重命名为X-PA-AUTH-TOKEN。

但请注意，如果你启用underscores_in_headers，你在烧瓶侧实际收到的东西将被重命名为X-Pa-Auth-Token，所以我想最好只是首先重命名标题而不用nginx设置。
