Golang - Nginx 代理通過問題

我有一個在埠 3001 上執行的 golang 應用程序。 curl http://127.0.0.1:3001給出正確的 HTML 響應。但是當我嘗試通過 NginX 進行 proxy_pass 時，我遇到了問題。

下面是我的 NginX 配置。我正在做一個基於路線的位置塊 -

upstream my-app {
   server 127.0.0.1:3001;
}

server {
       listen       80 default_server;
       server_name  localhost;
       underscores_in_headers on;
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       error_page 404 /404.html;
       client_max_body_size 300M;

           location ^~ /theapp {               
               proxy_redirect   off;
               proxy_set_header Host              $http_host;
               proxy_set_header X-Real-IP         $remote_addr;
               proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
               proxy_set_header X-Forwarded-Proto $scheme;

               proxy_pass       http://my-app;
           }
}

當我訪問http://example.com/theapp/時，它會下載my-app二進製文件，而不是將 http 請求轉發到 my-app。

我究竟做錯了什麼？

輸出nginx -T-

我已經通過/在末尾添加來解決它http://my-app。

不太確定它是如何工作的。但它確實奏效了。
