具体学爬虫的过程中遇到了这个问题,按照网络上面的教程,爬图片爬到一半就卡死了,下面是代码
import re
import requests#url = 'http://image.baidu.com/search/flip?tn=baiduimage&ipn=r&ct=201326592&cl=2&lm=-1&st=-1&fm=result&fr=&sf=1&fmq=1460997499750_R&pv=&ic=0&nc=1&z=&se=1&showtab=0&fb=0&width=&height=&face=0&istype=2&ie=utf-8&word=%E5%B0%8F%E9%BB%84%E4%BA%BA'
url = 'http://image.baidu.com/search/flip?tn=baiduimage&ipn=r&ct=201326592&cl=2&lm=-1&st=-1&fm=result&fr=&sf=1&fmq=1501470791167_R&pv=&ic=0&nc=1&z=&se=1&showtab=0&fb=0&width=&height=&face=0&istype=2&ie=utf-8&ctd=1501470791180%5E00_1899X935&word=%E5%9B%A2%E5%AD%90%E5%B0%91%E5%A5%B3'
html = requests.get(url).text
pic_url = re.findall('"objURL":"(.*?)",',html,re.S)
i = 0
for each in pic_url:print(each)try:pic= requests.get(each, timeout=10)except requests.exceptions.ConnectionError:print( '【错误】当前图片无法下载')continuestring = 'picture1\\'+str(i) + '.jpg'fp = open(string,'wb')fp.write(pic.content)fp.close()i += 1
检查以后发现是百度所在的页面该图片虽然收录在自己的机器上,所以你还能看见,但是实际连接已经失效,只能在缩略图上看到
仔细查看错误信息发现返回的错误信息是
requests.exceptions.ReadTimeout:
而不是代码中的
except requests.exceptions.ConnectionError:
我查了一下这两个错误的区别,发现区别不是很大,一般来说readtimeout出现的原因是该网页点击以后加载特别慢,而后者就是直接显示连接错误类型的,大部分的人在验证这里的连接错误的时候都是同时加的验证(这里也对这个程序原来的作者表示不要偷懒,博客上教东西教一半,太坑爹了)
