help request: How to set the upstream host dynamically

[KamenRiderKuuga]

Description

I'm trying to set the upstream host dynamically and unknown in advance like this:

remote_uri: /api/data-manage/... then set the host to: data-manage

I've tried the proxy-rewrite and the custom balancer, but still can't get this to work.

Is there any suggestion?

Can you show an example config of route that you tried with which didn't work?

No example configuration now.

I want to set the request regexp like this:

In this way, when requesting /api/data-manage/users, the http://data-manage/api/data-manage/users will be requested.

Thanks, I'll try it.

@qihaiyan I tried the traffic-split, it can't dynamically assign value to upstream_host according to the URI regexp.

Maybe you should develop your own plugin with reference to traffic-split.

this is not supported.

I have the same problem, and I write a custom plugin to achieve this.

checkout my gits: https://gist.github.com/br41n10/e2d378c7a04d4861b2f0cbf4d2476d71

This is a very basic implementation, modify on your needs.
