IBrowserHostSendDevToolsMessage Method

Send a method call message over the DevTools protocol. message must be a UTF8-encoded JSON dictionary that contains "id" (int), "method" (string) and "params" (dictionary, optional) values. See the DevTools protocol documentation at https://chromedevtools.github.io/devtools-protocol/ for details of supported methods and the expected "params" dictionary contents. message will be copied if necessary. This method will return true if called on the CEF UI thread and the message was successfully submitted for validation, otherwise false. Validation will be applied asynchronously and any messages that fail due to formatting errors or missing parameters may be discarded without notification. Prefer ExecuteDevToolsMethod if a more structured approach to message formatting is desired. Every valid method call will result in an asynchronous method result or error message that references the sent message "id". Event messages are received while notifications are enabled (for example, between method calls for "Page.enable" and "Page.disable"). All received messages will be delivered to the observer(s) registered with AddDevToolsMessageObserver. See OnDevToolsMessage(IBrowser, Stream) documentation for details of received message contents. Usage of the SendDevToolsMessage, ExecuteDevToolsMethod and AddDevToolsMessageObserver methods does not require an active DevTools front-end or remote-debugging session. Other active DevTools sessions will continue to function independently. However, any modification of global browser state by one session may not be reflected in the UI of other sessions. Communication with the DevTools front-end (when displayed) can be logged for development purposes by passing the `--devtools-protocol-log-file=<path>` command-line flag.
