描述

According to the protocol, Runtime#getProperties contains a parameter ownProperties with the following documentation: If true, returns properties belonging only to the element itself, not to its prototype chain.. While it's not clear what happens if ownProperties is false, I assume it should return all properties (not just it's own properties). However, Stetho is currently returning an empty array. When I connected to ChromeDevTools, it passes false for this value, meaning nothing is showing up in Scope Variables view.

研究方向
Examine the implementation of Runtime.getProperties in Stetho's CDP handler (likely in a Java class under the 'runtime' package). The protocol JSON indicates that when ownProperties is false, all properties including prototype chain should be returned. Currently it returns empty array. Look for the method that builds the property list and ensure it iterates over the entire prototype chain when ownProperties is false. Reference the protocol JSON from the Stetho repository.
