HTTP requests can be sent to any URL via the HTTP gateway. This can also be used to control other devices, which have a web or REST service. For this purpose, an HTTP gateway (as a device) must be detected. You have to enter the HTTP Gateway manually (Add Device / Add manually).
No matching from Mac address to IP can be determined on devices with Android version 10 and higher and on iOS devices. In this case, a HTTP Gateway must be registered with a fixed IP (you have to configure on the router).
An HTTP gateway has no targets. HTTP requests are registered directly at the gateway as a command.
For registering a command you have to enter a uinqieu ID, which you
use later for processing the request from you layout page. As request
type there is GET, POST, PUT, PATCH and DELETE at your disposal.
Depending on request type you can also add content (for example XML
or JSON) for transmit additional data the service you are calling.
The response content you can analyse with a response event (have also a look to the chapter Events). You can catch this events on the controls on your layout pages for manipulation and Controlling.
A system event will be sent with the ID of the HTTP Device and the parameters configures at this place.
The response will be analyzed the the regular expression. You have 2 different possibilities to analyzse the Response:
- Match
The HTTP Response will be compared with the regular expression (match). If the expression matches the event will be sent. - Search
The HTTP Response will be scaned for a string (search). The found string will be sent as value with the Event. You have to configure as Value «#value», so the system could recognize that the regular expression is a search expression and the result can be transmitted as value.
You will find an expample how a REST-Service call can be implemented in the chapter REST-Service.
