PostWebForm Method
Posts a web form data to the server.
Syntax
httpclient.postWebForm(url, fields, fileField, fileName, contentType, [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 variant of the POST method provides means to submit a form (as in a web browser) with an optional file attachment. Fields are expected to contain a list of field names and values in "Name=Value" format separated with EOLs. This list can be empty.
If including a file with your request, use the FileField and FileName properties to specify the file field name and the local filename for the uploaded file. Use ContentType to override the default content type chosen by the client, e.g., "application/x-www-form-urlencoded".
Note that any parameters you intend to pass to this method should be properly encoded before this method is called.
