【随手记录】nginx代理特殊字符 + 等转码导致报错问题

nginx配置如下：

set $target_path $request_uri;
if ($target_path ~ "^/api/prod/220/8090/(?<rest>.*)$") {
       set $target_path $rest;
}
if ($target_path ~ "^(.*)%25(.*)$") { set $target_path $1%$2; }

proxy_pass http://1.1.1.22:8090/$target_path; 

可以开启wireshark，追踪下http请求，看下请求是否按照需求转码
