help request: proxy-rewrite plugin didn't work as expected

[cookier]

Description

I used proxy-rewrite plugin want to forward request, like a.com/xx to b.com/yy，this is my configration:

{
  "uri": "/sq-baidu",
  "name": "proxy-rewrite",
  "methods": [
    "GET"
  ],
  "host": "sqtest.matrix.dev.xxxxx.com.cn",
  "plugins": {
    "proxy-rewrite": {
      "host": "10.200.106.112:30369",
      "uri": "/project/getProjectDomainName"
    }
  },
  "upstream": {
    "nodes": [
      {
        "host": "34535.top",             #is httpbin server
        "port": 8530,
        "weight": 1
      }
    ],
    "type": "roundrobin"
  },
  "status": 1
}

this is curl result from 10.200.106.112:30369

$ curl http://10.200.106.112:30369/project/getProjectDomainName
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100    82    0    82    0     0   1555      0 --:--:-- --:--:-- --:--:--  
{"code":0,"data":"http://matrix.dev.xxxxxxx.com.cn","success":true,"message":""}

so when I curl sqtest.matrix.dev.xxxxx.com.cn/sq-baidu, I expect the same result as above, but actually requested 34535.top. Why was it not forwarded to 10.200.106.112:30369?

$ curl --location --request GET 'sqtest.matrix.dev.xxxxxxx.com.cn/sq-baidu'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   475  100   475    0     0   1357      0 --:--:-- --:--:-- --:--:--  1361
{"args":{},"header":{"x-real-ip":"172.18.5.244","x-request-id":"d46faa7c-3ed1-4e39-b850-71a6f01368b7","x-forwarded-proto":"http","x-forwarded-host":"sqtest.matrix.dev.xxxxxxxx.com.cn","host":"10.200.106.162:30469","x-forwarded-port":"9080","x-forwarded-user-agent":"curl/7.80.0","user-agent":"curl/7.80.0","accept":"*/*"},"host":"58.218.131.211","uri":"/project/getProjectDomainName"}

This is access log, it looks normal. I wonder why the plug-in doesn't work properly. Is it my wrong way of using it?

172.11.52.44 - - [10/Aug/2022:21:10:33 +0800] sqtest.matrix.dev.xxxxxxx.com.cn "GET /sq-baidu HTTP/1.0" 200 475 0.015 "-" "curl/7.80.0" 111.91.156.229:8530 200 0.013 "http://10.200.106.112:30369/project/getProjectDomainName"

proxy-rewrite doesn't change the destination, but modifies the request.

You can use traffic split plugin to proxy to another upstream, or using redirect plugin and let the client redirects to the new location.

I misunderstood the usagfe of proxy-rewrite plugin. Redirect plugin relying on the 302 jump is not considered. And traffic split plugin can not modify uri ? I don't see the URI configuration in the documentation.

Try to combine the proxy-rewrite and traffic-split plugin?

Thanks for your suggestion, it's feasible.
