Post Method

Posts data to the HTTP server using the HTTP POST method.

Syntax

json.post(URL, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method posts data to the HTTP server using the HTTP POST method. The posted data is taken from the PostData property.

The server response text is parsed by the component, and may be access through properties like XPath, XElement, XText, etc. or the TransferredData property. The HTTP response headers are received through the Header event. If LocalFile is not empty the data (not the headers) is written there as well.
