Overview

Handling the leave when opening an HTTP session

Description

RHTTPSession::OpenL leaves with KErrNotFound if the Internet AP is not correctly configured - this is probably the first problem anyone encounters when using the HTTP API on a device because OpenL works with most SDKs on the emulator with default AP configuration.

The solution is to TRAP the leave and instruct the user to configure the Internet AP.

// Open RHTTPSession with default protocol ("HTTP/TCP")
  TRAPD(err, iSession.OpenL());
  if(err != KErrNone)
  &nbsp;&nbsp;&nbsp;&nbsp; <nowiki>{</nowiki>
  &nbsp;&nbsp;&nbsp; // Most common error; no access point configured, and
  &nbsp;&nbsp;&nbsp; // session creation leaves with KErrNotFound.
  &nbsp;&nbsp;&nbsp; _LIT(KErrMsg, "Cannot create session. Is internet access point configured?");
  &nbsp;&nbsp;&nbsp; _LIT(KExitingApp, "Exiting app.");
  &nbsp;&nbsp;&nbsp; CEikonEnv::Static()-<nowiki>></nowiki>InfoWinL(KErrMsg, KExitingApp);
  &nbsp;&nbsp;&nbsp; User::Leave(err);
  &nbsp;&nbsp;&nbsp; <nowiki>}</nowiki>
