bzp2010 opened a new issue, #8167:
URL: https://github.com/apache/apisix/issues/8167
### Current Behavior
The route configuration (omitted some irrelevant content):
```
{
"uri": "/v1/hello/*",
"plugins": {
"proxy-mirror": {
"sample_ratio": 1,
"host": "http://mirror.api:8082";
},
"proxy-rewrite": {
"regex_uri": [
"/v1/(.*)",
"/$1"
],
"_meta": {
"priority": 2000
}
}
}
}
```
The client uses this URI to request:
```
GET /v1/hello
```
Requests to the upstream will be rewritten as:
```
GET /hello
```
But the request to the mirror address is still:
```
GET /v1/hello
```
**So the URI rewritten in `proxy-rewrite` does not actually take effect for
`proxy-mirror`. (I have overridden the proxy-rewrite priority via
`_meta.priority` and it will be executed first)**
### Expected Behavior
The modified URI in `proxy-rewrite` will take effect for `proxy-mirror`.
### Error Logs
_No response_
### Steps to Reproduce
1. Create a route by referring to the route configuration in the current
behavior.
2. Request API
3. Check mirror service log
Explanation of reasons:
`proxy-rewrite` gets the URI from `ctx.var.uri`, writes it to the
`upstream_uri` variable, and subsequently uses that variable instead of the
original `uri` when forwarding upstream. `proxy-mirror` does not take this into
account and uses the original `uri` variable directly. I think it should behave
in such a way that the `uri` is used first and the `upstream_uri` is used when
the value does not match the `upstream_uri`.
### Environment
- APISIX version (run `apisix version`): 2.15.0
