python 下载图片

Posted 2020-10-03

from bs4 import BeautifulSoup
import urllib.request
request=urllib.request.Request(‘https://ss3.bdstatic.com/70cFv8Sh_Q1YnxGkpoWK1HF6hhy/it/u=3193006289,3802606706&fm=26&gp=0.jpg‘)
response=urllib.request.urlopen(request)
data=response.read()
print(data)
with open(‘first_down.jpg‘,‘wb‘) as fp:
    fp.write(data)
    print("download finished")

　　在看书的时候有点迷糊。尝试自己弄下。大概步骤是先找到图片的网址。通过urllib解析网址之后得到data数据。 然后通过open函数写道firs_img.jpg文件中。这个是最关键的步骤
