代码主要是大神写的：[https://cuiqingcai.com/5534.html][https_cuiqingcai.com_5534.html]

需要看具体细节的去该网址：

 response = requests.get(url,headers=header)
 if response.status_code == 200:
 return response.text
 return None
 except RequestException:
 return None

 f.write(json.dumps(content, ensure_ascii=False) + '\n')

 print(item) #比较有规律，F12打开源码看看
 write_to_file(item)

 time.sleep(1)
