python爬取图片
本文共 943 字，大约阅读时间需要 3 分钟。
baidu图片打开 ——发现是瀑布流，此时可以改成分页模式
将index改为flip
就可以改为分页模式了
查看网页源代码，查询objURL——最清晰
打开后续网页url就可以得到图片,获取url后可以requests了
示例
此时：只爬取了一张图片，那么通过不同url的切换可以爬取多种图片了
如果图片地址末尾没有jpg可以自己加
# 思路：拿到目标url 获取网页源码 获取图片url地址 保存图片url ='https://image.baidu.com/search/flip?tn=baiduimage&ipn=r&ct=201326592&cl=2&lm=-1&st=-1&fm=result&fr=&sf=1&fmq=1619608652857_R&pv=&ic=&nc=1&z=&hd=&latest=©right=&se=1&showtab=0&fb=0&width=&height=&face=0&istype=2&ie=utf-8&sid=&word=%E8%8B%8D%E5%8F%B6'headers ={ 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.104 Safari/537.36'}r =requests.get(url=url,headers=headers)ret=r.textprint(ret)# 获取图片url地址result =re.findall(r'"objURL":"(.*?)"',ret)print(result)for url in result: # 获取图片的名字 name =url[-10:] print(name) with open('图片/'+name+'.jpg','wb')as f: r =requests.get(url) f.write(r.content) 就取到了
注意：由于是瀑布流，所以网页格式有点改变，因此正则出来结果会不同，依然可以爬取不影响结果
