json.dump(response_json,fp=fp,ensure_ascii=False)
一直显示Traceback (most recent call last):

response_json = response.json()

最后一行改成这个再试试
response_json.dump(response_json, fp=fp, ensure_ascii=False)
post能正常返回页面信息，但不是json格式的，所以报json解码错误，你将response_json = response.text,print(response_json）就可看到。需要在header中添加参数比如cookie(token)或其他参数
