The HTTP/2 Client agent allows you to configure an HTTP client in a real-time workflow. The agent sends requests by converting the UDRs to HTTP 2 requests, and then receives the responses which are then routed into the workflow.
The agent can be used for both HTTP/1 and HTTP/2.
To be able to use the HTTP/2 Client agent, this processing agent must be preceded by an Analysis agent in the workflow that you create. The APL code must include a RequestCycle object as shown in the example APL code below. In the APL code, you must ensure that
req.secure
is set to true
and that req.httpVersion
is set to http2
.
consume { http.RequestCycle req = udrCreate(http.RequestCycle); req.host = "myserver"; req.port = "8181"; req.secure = true; req.httpVersion = "http2"; req.path = "/nf-instance"; req.method = "GET"; debug("sending request"+req); udrRoute(req); }
