sendAndReadAsync
open fun sendAndReadAsync(msg: Message, ioPriority: <Error class: unknown class>, cancellable: <Error class: unknown class>? = null, callback: <Error class: unknown class>?)
Asynchronously sends @msg and reads the response body.
When @callback is called, then either @msg has been sent, and its response body read, or else an error has occurred. This function should only be used when the resource to be retrieved is not too long and can be stored in memory. Call method@Session.send_and_read_finish to get a struct@GLib.Bytes with the response body.
See method@Session.send for more details on the general semantics.
Parameters
msg
a #SoupMessage
ioPriority
the I/O priority of the request
