You can call the callback function when the request is successful. Parameters: url, [data], [callback], and [type] correspond to the following parameter types: String, Map, Function, String:

●Url: Send request address.

●Data: Key/value parameter to be sent.

●Callback: Callback function when sending successfully.

●Type: Returned content format, xml, html, script, json, text, _ default)
