HTTP/2 Client Agent
- Kevin Wu
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.Â
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);
