如果原始请求不存在，nginx 重定向失败

Question

问题陈述：当原始请求是不存在的位置时，nginx 似乎不会重定向。所有其他重定向似乎都工作正常。也有可能 php 没有在重定向页面上执行脚本。下面提供了 nginxconf。

问题：我缺少什么以及我需要做什么才能完成这项工作？ nginx 是否可能不支持从不存在的页面进行重定向？

一些上下文可能会有所帮助：这是一个正在重定向的典型请求：

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 "-" "-"

请注意，没有针对此请求的页面显示；该请求被转储到缓冲区中，进行处理并写入数据库。请参阅本文末尾以获取 nginx 调试日志的摘录。

更改 URL 是不切实际的，因为有数十个单位分散在世界各地。大多数设备无法远程更新。

原来的站点现在不再使用，使用的是apache。当前站点使用nginx。我不太熟悉网络服务器，所以我可能错过了一些明显的东西。所有想法都将受到赞赏。

我还在端口 80 服务器块中尝试了以下操作：

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

Answer 1

如果我对发起此请求的软件无法解释 302 HTTP 重定向代码并发出新请求的猜测是正确的，那么您唯一的方法就是在 HTTP 块本身内处理该请求。而不是您当前的

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

您可以检查此配置：

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，您的请求将开始出现在数据库中，这肯定意味着我最初的猜测是正确的。
