[purekeeper]

Issue description

I do the demo follow https://apisix.apache.org/docs/apisix/plugins/proxy-rewrite
step1 : curl add route and plugin
step2: curl -X GET http://127.0.0.1:9080/test/index.html,
but i get 502 and the request log is not same with you said ,I think it does not rewite the host to "http://iresty.com/test/home.html .Anybody tell me why ?

Environment

• apisix version (cmd: apisix version):
• OS (cmd: uname -a):
• OpenResty / Nginx version (cmd: nginx -V or openresty -V):
• etcd version, if have (cmd: run curl http://127.0.0.1:9090/v1/server_info to get the info from server-info API):
• apisix-dashboard version, if have:
• the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner):
• luarocks version, if the issue is about installation (cmd: luarocks --version):

Hello there, It just a demo, which mean that you need to change the upstream and host to make it work.

@leslie-tsang Please look the demo again, I think it not relate with the upstream, I think any request with uri /test/index.html will be forward to http://iresty.com/test/home/html, because the proxy-rewrite plugin rewrite the request right ?

I afraid the answer is no.
The request will be send to http://127.0.0.1:80/test/index.html with the request header host: iresty.com

The 502 error occur as there is no service listen to 127.0.0.1:80

You can try the following CMD to test if it achieves your goal

curl http://127.0.0.1:9080/apisix/admin/routes/1  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "methods": ["GET"],
    "uri": "/test/index.html",
    "plugins": {
        "proxy-rewrite": {
            "uri": "/test/home.html",
            "scheme": "http",
            "host": "iresty.com",
            "headers": {
                "X-Api-Version": "v1",
                "X-Api-Engine": "apisix",
                "X-Api-useless": ""
            }
        }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "iresty.com:80": 1
        }
    }
}'
