我读取json文件，显示乱码。

[kof0012]

我抓今日头条的json，出现raise JSONDecodeError("Expecting value", s, err.value) from None
���������
出现类似这样的乱码。

@kof0012 是我gzip处理的时候的问题，你更新一下版本（0.0.3）即可。

python -m pip install trip -U

@littlecodersh 感谢回复，另外请问怎么在trip.run(fun)里写参数。实现trip.run(fun(args))，还是抓今日头条的json文件，想要递归回调（带参数），想了半天想不出来办法。。求教。
