Sorry, I know this question that is related to Chrome DevTools Protocol. But, I help you can help me. :(

I'd like to get some local variables in a javascript function. My idea is setting some breakpoints, executing and then showing the debugger.scope to capture the local variables. However, I don't know how to start with ichrome....

That's a good question. Someone asked me last year, but I didn't try that yet. Maybe you can find the objectId of local or closure functions by cdp.

Years before, I tried using Fetch method as a Man-in-the-middle (MITM) attacks to update those JS functions, and then add new hook code to them.

Thank for reply. Fetch is https://chromedevtools.github.io/devtools-protocol/tot/Fetch/? If it's, which method you would suggest? could you give me more concrete details? And How to capture the objectId? Sorry, I'm an newbie.

Yup, Fetch could modify the response.

objectId you can learn it from google, I didn't use that before.
