Method that will be called on receipt of a DevTools protocol message. |browser| is the originating browser instance. |message| is a UTF8-encoded JSON dictionary representing either a function result or an event. |message| is only valid for the scope of this callback and should be copied if necessary. Return true (1) if the message was handled or false (0) if the message should be further processed and passed to the OnDevToolsMethodResult or OnDevToolsEvent functions as appropriate.
|
|
|
|
<p>Method result dictionaries include an "id" (int) value that identifies the orginating function call sent from ICefBrowserHost.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 "function" (string) value and optionally a "params" (dictionary) value. See the DevTools protocol documentation at <a href="https://chromedevtools.github.io/devtools-protocol/">https://chromedevtools.github.io/devtools-protocol/</a> for details of supported function 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). </p>

Method that will be called after attempted execution of a DevTools protocol function. |browser| is the originating browser instance. |message_id| is the "id" value that identifies the originating function call message.
