upstream proxy info rewrite plugin.

Attributes

Name Type Requirement Default Valid Description
scheme string optional "http" ["http", "https"] Upstream new schema forwarding protocol
uri string optional Upstream new uri forwarding address.
regex_uri array[string] optional Upstream new uri forwarding address. Use regular expression to match URL from client, when the match is successful, the URL template will be forwarded upstream. If the match is not successful, the URL from the client will be forwarded to the upstream. When uri and regex_uri are both exist, uri is used first. For example: [" ^/iresty/(.)/(.)/(.*)", "/$1-$2-$3"], the first element represents the matching regular expression and the second element represents the URL template that is forwarded to the upstream.
host string optional Upstream new host forwarding address, example iresty.com.
headers object optional Forward to the new headers of the upstream, can set up multiple. If it exists, will rewrite the header, otherwise will add the header. You can set the corresponding value to an empty string to remove a header.

How To Enable

Here's an example, enable the proxy rewrite plugin on the specified route:

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": {
            "127.0.0.1:80": 1
        }
    }
}'

Test Plugin

Testing based on the above examples :

curl -X GET http://127.0.0.1:9080/test/index.html

Send the request and see upstream `access.log', if the output information is consistent with the configuration :

127.0.0.1 - [26/Sep/2019:10:52:20 +0800] iresty.com GET /test/home.html HTTP/1.1 200 38 - curl/7.29.0 - 0.000 199 107

This means that the proxy rewrite plugin is in effect.

Disable Plugin

When you want to disable the proxy rewrite plugin, it is very simple, you can delete the corresponding json configuration in the plugin configuration, no need to restart the service, it will take effect immediately :

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": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:80": 1
        }
    }
}'

The proxy rewrite plugin has been disabled now. It works for other plugins.
