proxy-control

Description

The proxy-control Plugin dynamically controls the behavior of the NGINX proxy.

IMPORTANT

This Plugin requires APISIX to run on APISIX-Runtime. See apisix-build-tools for more info.

Attributes

Name	Type	Required	Default	Description
request_buffering	boolean	False	true	When set to true, the Plugin dynamically sets the proxy_request_buffering directive.

Enable Plugin

The example below enables the Plugin on a specific Route:

note

You can fetch the admin_key from config.yaml and save to an environment variable with the following command:

admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g')

curl -i http://127.0.0.1:9180/apisix/admin/routes/1 \
  -H "X-API-KEY: $admin_key" -X PUT -d '
{
    "uri": "/upload",
    "plugins": {
        "proxy-control": {
            "request_buffering": false
        }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'

Example usage

The example below shows the use case of uploading a big file:

curl -i http://127.0.0.1:9080/upload -d @very_big_file

It's expected to not find a message "a client request body is buffered to a temporary file" in the error log.

Delete Plugin

To remove the proxy-control Plugin, you can delete the corresponding JSON configuration from the Plugin configuration. APISIX will automatically reload and you do not have to restart for this to take effect.

curl -i http://127.0.0.1:9180/apisix/admin/routes/1 \
  -H "X-API-KEY: $admin_key" -X PUT -d '
{
    "uri": "/upload",
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'
