Description

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

:::info IMPORTANT

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

Attributes

NameTypeRequiredDefaultDescription
request_bufferingbooleanFalsetrueWhen 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:

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

:::

shell
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:

shell
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.

shell
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
        }
    }
}'
