拿着老师的源码，debug save_cookies_to_file(driver)时候一直报错：JSONDecodeError

Question

代码是老师的源码（路径修改为本地自己的了）具体报错：
C:\Python37\python.exe “C:\Program Files\JetBrains\PyCharm Community Edition 2018.1.4\helpers\pydev\pydevd.py” --multiproc --qt-support=auto --client 127.0.0.1 --port 51804 --file D:/project/project/part_two/jingdong2.py

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)这句话比较关键，json解析有问题，你看看数据。
