目標應用程式資產未使用 nginx proxy_pass 加載

Question

我有一個基本的 nginx 代理運行在http://127.0.0.1:8080.

這是nginx.conf：

events {}
http { 
    server {
        listen 8080;
        server_name 127.0.0.1;
        rewrite_log on;
        error_log  /var/log/nginx/error.log notice;


        location / {
            proxy_pass http://127.0.0.1:5200;
            proxy_set_header  Host 127.0.0.1:5200;
        }
        location /api {
            proxy_pass http://127.0.0.1:8000;
            proxy_set_header  Host 127.0.0.1:8000;
        }
        location = /app2 {
            return 302 /app2/;
        }
        location /app2/ {
            proxy_pass http://127.0.0.1:5300/;
            proxy_set_header  Host 127.0.0.1:5300; 
        }

    }
}

點擊 時http://127.0.0.1:8080/app2，會顯示在連接埠上執行的應用程序5300，但資源未正確載入。我懷疑 nginx 將對資產的請求代理到在端口上運行的另一個應用程序5200，即location /.我停止了這個應用程式來確認，這是來自 nginx 的日誌（請注意，上游顯示為，http://127.0.0.1:5200...但它應該是http://127.0.0.1:5300...）

來自控制台的錯誤：

我看到類似的問題http://127.0.0.1:8080/api，資產未加載。我也嘗試使用 diff 正規表示式組合重寫規則，但遇到了類似的錯誤。

如何配置 nginx 以路由到不同的應用程式並正確載入其資源。

Answer 1

經過進一步挖掘和測試，rewrite解決方案詳述於https://stackoverflow.com/questions/62836801/nginx-reverse-proxy-how-to-serve-multiple-apps在我的案例中起作用。

這是我新增到 nginx.conf 中以正確載入 app2 資源的程式碼片段

if ($http_referer ~ https?://[^/]+/app2/(.*))
{
    # rewrite request URI only if it isn't already started with '/app2' prefix
    rewrite ^((?!/app2).*) /app2$1;
}
