无法使用urllib2从网络保存图像

Question

我想使用python从网站保存一些图像urllib2但是当我运行代码时它会保存其他东西.

这是我的代码:

user_agent = 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'
headers = { 'User-Agent' : user_agent }
url = "http://m.jaaar.com/"
r = urllib2.Request(url, headers=headers)
page = urllib2.urlopen(r).read()

soup = BeautifulSoup(page)
imgTags = soup.findAll('img')
imgTags = imgTags[1:]


for imgTag in imgTags:
    imgUrl = "http://www.jaaar.com" + imgTag['src']
    imgUrl = imgUrl[0:-10] + imgUrl[-4:]
    fileName = "khabarnak-" + imgUrl[-12:]
    print fileName

    imgData = urllib2.urlopen(imgUrl).read()
    print imgUrl

    output = open("C:\wamp\www\py\pishkhan\\" + fileName,'wb')
    output.write(imgData)
    output.close()

有什么建议？

该网站正在将标准图像返回给您,因为您正在抓取该网站.在检索图像时使用相同的"技巧"来设置标题:

imgRequest = urllib2.Request(imgUrl, headers=headers)
imgData = urllib2.urlopen(imgRequest).read()
