IDevToolsMessageObserverOnDevToolsMessage Method

Version 101.0.180
Method that will be called on receipt of a DevTools protocol message. Method result dictionaries include an "id" (int) value that identifies the orginating method call sent from IBrowserHost.SendDevToolsMessage, and optionally either a "result" (dictionary) or "error" (dictionary) value. The "error" dictionary will contain "code" (int) and "message" (string) values. Event dictionaries include a "method" (string) value and optionally a "params" (dictionary) value. See the DevTools protocol documentation at https://chromedevtools.github.io/devtools-protocol/ for details of supported method calls and the expected "result" or "params" dictionary contents. JSON dictionaries can be parsed using the CefParseJSON function if desired, however be aware of performance considerations when parsing large messages (some of which may exceed 1MB in size).
