Nginx重定向到另一个域并附加新参数

Question

I'm trying to redirect all traffic from my www.old-domain.com to www.new-domain.com , while keeping all path and query parameters in the url, and append a new query parameter such as &from-old=true .

For example

www.old-domain.com --> www.new-domain.com/?from-old=true
www.old-domain.com/home --> www.new-domain.com/home?from-old=true
www.old-domain.com/item?id=123 --> www.new-domain.com/item?id=123&from-old=true

Please share some thoughts about how I should rewrite/return the url in Nginx to achieve this.

Thanks in advance!

If you are adding additional arguments to the query string to a URI that may or may not already have a query string, then you should use a rewrite directive, as that will handle the edge conditions correctly. See this document for details.

For example:

rewrite ^ $scheme://example.com$uri?from-old=true permanent;
