照着书爬豆瓣电影出错
百度了半天实在是搞不懂
就三行而已....

1. import requests
   
2. res = requests.get("https:/movie.douban.com/250")
   
3. print(res.text)

复制代码

结果报错

连模拟浏览器头都木有，人家铁定认为你是爬虫

InvalidURL意思就是无效url，说明网址不对

有两个斜杆，把代码改成这样：

1. import requests
   
2. res = requests.get("https://movie.douban.com/top250")
   
3. print(res.text)
