我正在尝试通过他们的个人资料页面获取Facebook用户的个人资料图片（如果这些图片可以在他们的公开个人资料中找到）
我很难通过漂亮的汤来获得它。
目前我正在使用以下代码查找图片链接的位置：
from urllib import urlopen
import mechanize
from bs4 import BeautifulSoup
br = mechanize.Browser()
br.set_handle_robots(False)
page_open = br.open("https://www.facebook.com/zuck")
x= soup.find(id="u_0_6") #change sometime with "u_0_5"
strx = str(x)
strx[2469:2690] #really bad choice
从最后一行开始，只有在前一个代码没有改变且永远不会发生的情况下，我才能提取网址。 如何获取数据

或者不是刮Facebook，你可以通过他们的图形API以正确的方式做到这一点;）
import requests
url = "http://graph.facebook.com/{}".format("zuck")
params = { "fields": "picture" }
response = requests.get(url, params=params).json()
picture_url = response['picture']['data']['url']
print(picture_url)
# output:
# https://fbcdn-profile-a.akamaihd.net/hprofile-ak-xfa1/v/t1.0-1/c14.4.153.153/s50x50/1939620_10101266232851011_437577509_n.jpg?oh=6b6cd8460210e1de160cf8a6056df416&oe=550D5F6C&__gda__=1429858477_b29a956770b6173d71cb28eb35fa99e6
说明：个人资料图片网址是一个公共字段 - 您可以在不进行身份验证的情况下访问它。
<强>优点：
requests比url lib 玩Facebook图表api：https://developers.facebook.com/tools/explorer

我不确定这是多么可靠，因为<code><!-- <div...对我来说看起来很奇怪，因为我对HTML知之甚少，但这段代码应该有效：
element= soup.find(id="u_0_6")
soup= BeautifulSoup(element.string)
image= soup.find('img', attrs={'class': ['profilePic']})
print image
