Nhờ câu trả lời của Corey ở trên và một ngày thứ bảy lười biếng với quá nhiều thời gian trên tay, giờ đây tôi có thể thấy danh sách các thông báo Chrome gần đây trong bảng điều khiển IDE của mình, nơi tôi thậm chí có thể nhấp vào URL.
Mã này là crappy và sử dụng heuristic thô vì tôi không có manh mối về cách chính xác để giải thích dữ liệu nhị phân.
Nhưng đó là một tấn còn hơn không. Ví dụ đầu ra (đoạn trích):
