如果原始請求不存在，nginx 重定向失敗

Question

問題陳述：當原始請求是不存在的位置時，nginx 似乎不會重定向。所有其他重定向似乎都工作正常。也有可能 php 沒有在重定向頁面上執行腳本。下面提供了 nginxconf。

問題：我缺少什麼以及我需要做什麼才能完成這項工作？ nginx 是否可能不支援從不存在的頁面進行重新導向？

一些上下文可能會有所幫助：這是一個正在重定向的典型請求：

73.234.24.22 - - [30/May/2022:16:15:05 +0000] "GET /postevent3.asp?dta=05%2f30%2f22%2016%3a15%3a22%20507%20%2b149642656%20%2d254084882%20%2d0001787%20682829361 HTTP/1.1" 302 154 "-" "-"

請注意，沒有針對此要求的頁面顯示；該請求被轉儲到緩衝區中，進行處理並寫入資料庫。請參閱本文末尾以獲取 nginx 調試日誌的摘錄。

更改 URL 是不切實際的，因為有數十個單位分散在世界各地。大多數設備無法遠端更新。

原來的網站現在不再使用，使用的是apache。目前站點使用nginx。我不太熟悉網頁伺服器，所以我可能錯過了一些明顯的東西。所有想法都將受到讚賞。

我還在連接埠 80 伺服器區塊中嘗試了以下操作：

location / {
    try_files $uri $uri/ /data/submit_legacy.php?$query_string;
}

Answer 1

如果我對發起此請求的軟體無法解釋 302 HTTP 重定向程式碼並發出新請求的猜測是正確的，那麼您唯一的方法就是在 HTTP 區塊本身內處理該請求。而不是您當前的

location = /postevent3.asp {
    return 302 https://example.org/data/submit_legacy.php?$query_string; 
}       

您可以檢查此配置：

location = /postevent3.asp {
    rewrite ^ /data/submit_legacy.php break;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$uri;
    fastcgi_pass unix:/run/php/php7.4-fpm.sock;
}

如果使用此配置，您的請求將開始出現在資料庫中，這肯定意味著我最初的猜測是正確的。
