执行时报错
>python.exe tickets.py -v
Traceback (most recent call last):
File "tickets.py", line 86, in <module>

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
但是我自己print(resp**e.json()['data']) 时输出正常
{'flag': '1', 'map': {'BJP': '北京', 'BXP': '北京西', 'CSQ': '长沙', 'CWQ': '长沙南'}, 'result': .....后面省略了
代码如下，麻烦各位大神看看是哪里出问题了。
