Remote controlling rclone

If rclone is run with the --rc flag then it starts an http server which can be used to remote control rclone.

FIXME describe other flags

Accessing the remote control via the rclone rc command

Rclone itself implements the remote control protocol in its rclone rc command.

You can use it like this

Accessing the remote control via HTTP

Rclone implements a simple HTTP based protocol.

Each endpoint takes an JSON object and returns a JSON object or an error. The JSON objects are essentially a map of string names to values.

All calls must made using POST.

The input objects can be supplied using URL parameters, POST parameters or by supplying "Content-Type: application/json" and a JSON blob in the body. There are examples of these below using curl.

The response will be a JSON blob in the body of the response. This is formatted to be reasonably human readable.

If an error occurs then there will be an HTTP error status (usually 400) and the body of the response will contain a JSON encoded error object.

Using POST with URL parameters only

curl -X POST 'http://localhost:5572/rc/noop/?potato=1&sausage=2'

Response

{
	"potato": "1",
	"sausage": "2"
}

Here is what an error response looks like:

curl -X POST 'http://localhost:5572/rc/error/?potato=1&sausage=2'

{
	"error": "arbitrary error on input map[potato:1 sausage:2]",
	"input": {
		"potato": "1",
		"sausage": "2"
	}
}

Note that curl doesn't return errors to the shell unless you use the -f option

$ curl -f -X POST 'http://localhost:5572/rc/error/?potato=1&sausage=2'
curl: (22) The requested URL returned error: 400 Bad Request
$ echo $?
22

Using POST with a form

curl --data "potato=1" --data "sausage=2" http://localhost:5572/rc/noop/

Response

{
	"potato": "1",
	"sausage": "2"
}

Note that you can combine these with URL parameters too with the POST parameters taking precedence.

curl --data "potato=1" --data "sausage=2" "http://localhost:5572/rc/noop/?rutabaga=3&sausage=4"

Response

{
	"potato": "1",
	"rutabaga": "3",
	"sausage": "4"
}

Using POST with a JSON blob

curl -H "Content-Type: application/json" -X POST -d '{"potato":2,"sausage":1}' http://localhost:5572/rc/noop/

response

{
	"password": "xyz",
	"username": "xyz"
}

This can be combined with URL parameters too if required. The JSON blob takes precedence.

curl -H "Content-Type: application/json" -X POST -d '{"potato":2,"sausage":1}' 'http://localhost:5572/rc/noop/?rutabaga=3&potato=4'

{
	"potato": 2,
	"rutabaga": "3",
	"sausage": 1
}
