nginx重定向失败，如果原始请求不存在

Question

问题陈述:当原始请求是一个不存在的位置时，Nginx似乎不会重定向。所有其他重定向似乎都工作得很好。也有可能php没有在重定向页面上执行脚本。Nginx配置文件如下:

问题:我错过了什么，我需要做些什么来完成这项工作?是否有可能nginx不支持从不存在的页面重定向?

一些上下文可能会有所帮助:下面是一个被重定向的典型请求:

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;请求被转储到缓冲区中，经过处理并写入数据库。请参阅本文末尾的nginx调试日志摘录。

改变URL是不现实的，因为有几十个单位分散在世界各地。大多数单元无法远程更新。

原来的网站，现在没有使用，使用apache。当前站点使用nginx。我不是很熟悉web服务器，所以我可能错过了一些明显的东西。我将不胜感激。

我还在80端口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

如果我猜测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是正确的，那么您唯一的方法是在HTTP块本身内处理请求。而不是你当前的

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

你可以检查这个配置:

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您的数据库中，这肯定意味着我最初的猜测是正确的。
