妍泽 · 发表于 2024-6-11 21:17:51

准备环境

springboot /redirect controller

curl http://localhost:10080/redirect -vv
* Trying ::1:10080...
* Connected to localhost (::1) port 10080 (#0)
> GET /redirect HTTP/1.1
> Host: localhost:10080
> User-Agent: curl/7.76.1
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 302
< X-Content-Type-Options: nosniff
< X-XSS-Protection: 1; mode=block
< Cache-Control: no-cache, no-store, max-age=0, must-revalidate
< Pragma: no-cache
< Expires: 0
< X-Frame-Options: DENY
< Location: http://localhost:10080/ip
< Content-Length: 0
< Date: Wed, 26 May 2021 05:55:45 GMT
<
* Connection #0 to host localhost left intact

复制代码

1. 默认配置

即proxy_redirect default;

location / {
proxy_pass http://localhost:10080/;
}

复制代码

效果

curl -vv http://localhost/redirect
* Trying ::1:80...
* connect to ::1 port 80 failed: 拒绝连接
* Trying 127.0.0.1:80...
* Connected to localhost (127.0.0.1) port 80 (#0)
> GET /redirect HTTP/1.1
> Host: localhost
> User-Agent: curl/7.76.1
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 302
< Server: nginx/1.19.3
< Date: Wed, 26 May 2021 05:57:02 GMT
< Content-Length: 0
< Location: http://localhost/ip
< Connection: keep-alive
< X-Content-Type-Options: nosniff
< X-XSS-Protection: 1; mode=block
< Cache-Control: no-cache, no-store, max-age=0, must-revalidate
< Pragma: no-cache
< Expires: 0
< X-Frame-Options: DENY
<
* Connection #0 to host localhost left intact

复制代码

2. proxy_redirect default;

location / {
proxy_pass http://localhost:10080/;
proxy_redirect default;
}

复制代码

注意，proxy_redirect default必须在proxy_pass下方配置
效果

curl -vv http://localhost/redirect
* Trying ::1:80...
* connect to ::1 port 80 failed: 拒绝连接
* Trying 127.0.0.1:80...
* Connected to localhost (127.0.0.1) port 80 (#0)
> GET /redirect HTTP/1.1
> Host: localhost
> User-Agent: curl/7.76.1
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 302
< Server: nginx/1.19.3
< Date: Wed, 26 May 2021 06:02:20 GMT
< Content-Length: 0
< Location: http://localhost/ip
< Connection: keep-alive
< X-Content-Type-Options: nosniff
< X-XSS-Protection: 1; mode=block
< Cache-Control: no-cache, no-store, max-age=0, must-revalidate
< Pragma: no-cache
< Expires: 0
< X-Frame-Options: DENY
<
* Connection #0 to host localhost left intact

复制代码

与方案1等同

3. proxy_redirect off;

location / {
proxy_pass http://localhost:10080/;
proxy_redirect off;
}

复制代码

效果

curl http://localhost:10080/redirect -vv
* Trying ::1:10080...
* Connected to localhost (::1) port 10080 (#0)
> GET /redirect HTTP/1.1
> Host: localhost:10080
> User-Agent: curl/7.76.1
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 302
< X-Content-Type-Options: nosniff
< X-XSS-Protection: 1; mode=block
< Cache-Control: no-cache, no-store, max-age=0, must-revalidate
< Pragma: no-cache
< Expires: 0
< X-Frame-Options: DENY
< Location: http://localhost:10080/ip
< Content-Length: 0
< Date: Wed, 26 May 2021 06:03:34 GMT
<
* Connection #0 to host localhost left intact

复制代码

可以看到，302响应的是内部地址。

总结

常规部署情况下，不需要特别配置proxy_redirect或者配置proxy_redirect default即可。
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
