NGINX 使用 cloudflare 重写子域路径导致重定向次数过多

NGINX 使用 cloudflare 重写子域路径导致重定向次数过多

我想要实现这样的 URL 重写:
https://documentation.domain.com/loginto https://app.domain.com/login
https://api.domain.com/loginto https://app.domain.com/login
,任何带有 URL {anything}.domain.com/login 的 sudomain 到https://app.domain.com/login

https://app.domain.com/sdkshttps://documentation.domain.com/sdks(保留所有查询参数)
https://api.domain.com/sdkshttps://documentation.domain.com/sdks(保留所有查询参数)
,任何带有 url {anything}.domain.com/sdks 的 sudomain 到https://documentation.domain.com/sdks

https://app.domain.com/restApihttps://documentation.domain.com/restApi(保留所有查询参数)
https://api.domain.com/restApihttps://documentation.domain.com/restApi(保留所有查询参数)
,任何带有 url {anything}.domain.com/restApi 的 sudomain 到https://documentation.domain.com/restApi

这是我目前拥有的:

Cloudflare SSL 我设置为完全严格。更改为完全/灵活不会改变任何东西。此设置基本有效。这有效但会导致 ERR_TOO_MANY_REDIRECTS 我该如何纠正这个问题?这里出了什么问题?请帮我解决这个问题
