Istio-使用URI正则表达式匹配进行URI重写 [英] Istio - URI Rewrite with URI Regex Match

问题描述

对于Istio来说还比较陌生，并且对Istio有疑问.假设我想基于路径重写URI，但是在重写中使用了原始uri的一部分，那是我可以用Regex来做的事情吗?我在想像这样的东西

So relatively new to Istio and have a question regarding Istio. Say that I want to rewrite a URI based on a path, but use part of that original uri in the rewrite, is that something I could do with Regex? I'm imagining something like this

http:
  - match:
    - uri:
       regex: ^/(.*\s*)?(canary)(.*)?$
    rewrite:
      prefix: "/$1"

其中$ 1是uri正则表达式上的匹配组.这样有可能吗?

Where $1 would be a matching group on the uri regex. Is something like that possible?

推荐答案

仅包含 HTTPMatchRequest .

Only those rule, which contain StringMatch type of values can work with regex. For example HTTPMatchRequest.

很遗憾，不 HTTPRewrite ，仅将strings作为值

Unfortunately NOT HTTPRewrite, which takes only strings as a value
