nginx - 如何编写用于替换查询字符串中的查询参数的 nginx 重写规则

Question

伙计们！

我们有以下http请求：

http://185.xxx.x.xx/auth/realms/master-realm/protocol/openid-connect/auth?response_type=code&client_id=regportal&redirect_uri=http%3A%2F%2Fsome.domain.com%2Fregportal%2Fsso% 2Flogin&state=a49a02d5-f873-453f-9148-61793f11ecf3&login=true&scope=openid

我们想redirect_uri从“some.domain.com”替换为“other.domain.com”。

怎么做？

谢谢

你需要这样做

location /auth/realms/master-realm/protocol/openid-connect/auth {
   if ($args ~* "(.*)(some\.domain\.com)(.*)") {
       set $args "$1other.domain.com$3";
       return 301 $scheme://$host$uri$args;
   }

}

测试：

curl -I  "vm/auth/realms/master-realm/protocol/openid-connect/auth?response_type=code&client_id=regportal&redirect_uri=http%3A%2F%2Fsome.domain.com%2Fregportal%2Fsso%2Flogin&state=a49a02d5-f873-453f-9148-61793f11ecf3&login=true&scope=openid"
