IDevToolsMessageObserverOnDevToolsMessage Method |
Version 89.0.170
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).
