Preconfiguration "HttpRequest - Receive or send (GET, POST)"
receive or send data by GET
This preconfiguration can be activated when creating a new object (e.g. by "New object ..."
in the local object menu or by pressing the Insert
key after selecting the object) and is included in the group: "/ Communication / Protocols and other communications / HTTP - XML, JSON, CSV, text"
This preconfiguration can be created in the object: PmaFolder
- The preconfiguration is created including the panel (object of the PmaPanel
type) is functional also a Web panel
object has the RequestGet
methods for initialization of the communication. Each of this methods calls the Add
method of the PmaSequencer
object, where in the second
prarameter the communication method is defined (GET or POST) and in the third
parameter the URL address
of the source is defined and in the fourth
parameter (for the POST method) there is the send data content. Additional methods ReplyXml
are used for processing the received data based on reply type.
Testing panel PmaPanel
allows to run methods RequestGet
and display unprocessed received data.
object is configured in order to have each communication running outside the main working thread of the PROMOTIC application. In the onStep
event, there is an ActiveX Microsoft.XMLHTTP
object that gets the corresponding parameters for synchronous mode communication by the open
method. The "send"
method follows and receives or sends the data. The received data can be then processed as needed. The transmission is terminated by the abort
These configurators can be set before the preconfiguration is created:
|The name of created object||Name of the object created in the tree of Pma objects. The maximum name length is 30 characters. This is a system name, so it must contain only alphanumeric and must not contain any diacritics (i.e. national dependent chars), empty string, spaces and the first character must not be a number.
