### [418 I'm a teapot](https://developer.mozilla.org/zh-TW/docs/Web/HTTP/Status/418)
```py
import requests

url = "https://movie.douban.com/cinema/later/beijing/"
page = requests.get(url)
print(page.status_code)
```
```
418
```

在头信息中加入 User-Agent 来解决。在 Safari 浏览器中通过选择菜单[开发]->[显示JavaScript控制台]，然后选择[网络]->[文稿]->[标头]，在内容里的[请求]节可以找到 User-Agent。
