Logging into facebook with python

Question

If I run the following code 10 times in a row, it will work about half the time and fail the rest. Anyone know why?

import urllib2, cookielib, re, os, sys

class Facebook():
    def __init__(self, email, password):
        self.email = email
        self.password = password

        cj = cookielib.CookieJar()
        opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
        opener.addheaders = [('Referer', 'http://login.facebook.com/login.php'),
                            ('Content-Type', 'application/x-www-form-urlencoded'),
                            ('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7 (.NET CLR 3.5.30729)')]
        self.opener = opener

    def login(self):
        url = 'https://login.facebook.com/login.php?login_attempt=1'
        data = "locale=en_US&non_com_login=&email="+self.email+"&pass="+self.password+"&lsd=20TOl"

        usock = self.opener.open('http://www.facebook.com')
        usock = self.opener.open(url, data)
        if "Logout" in usock.read():
            print "Logged in."
        else:
            print "failed login"
            print usock.read()
            sys.exit()

f = Facebook("test@gmail.com", "asdfasdf")
f.login()

Answer 1

所以我尝试了你的代码,并让它登录一次,然后像你一样我再次登录时遇到问题.在'if'语句之前的一行上,我添加了print usock.read()并最终获得了一堆html代码.然后我将该代码放入记事本中,将其保存为html文件,然后将其拉出来.这就是正在发生的事情:Facebook怀疑我们是从计算机程序登录的,并且正在等待我们通过显示验证字来验证我们是否真实.该程序没有考虑到这一点,并且当它真的更多是挂起登录时打印"登录失败".

我遇到了同样的问题.我找到的唯一解决方案是... facebook mobile更稳定.

class Acc:
    jar = cookielib.CookieJar()
    cookie = urllib2.HTTPCookieProcessor(jar)       
    opener = urllib2.build_opener(cookie)

    headers = {
        "User-Agent" : "Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.8.1.14) Gecko/20080609 Firefox/2.0.0.14",
        "Accept" : "text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,text/png,*/*;q=0.5",
        "Accept-Language" : "en-us,en;q=0.5",
        "Accept-Charset" : "ISO-8859-1",
        "Content-type": "application/x-www-form-urlencoded",
        "Host": "m.facebook.com"
    }

    def login(self):
        try:
            params = urllib.urlencode({'email':'test@test.test','pass':'dempassword','login':'Log+In'})
            req = urllib2.Request('http://m.facebook.com/login.php?m=m&refsrc=m.facebook.com%2F', params, self.headers)
            res = self.opener.open(req)
            html = res.read()

            #print res.getheader('location').split('/')[3]

        except urllib2.HTTPError, e:
            print e.msg
        except urllib2.URLError, e:
            print e.reason[1]
        return False

    def fetch(self,url):
        req = urllib2.Request(url,None,self.headers)
        res = self.opener.open(req)
        return res.read()

bla = Acc()
bla.login()

此外,Facebook移动版没有填充ajax,因此搞清楚要求制作的内容要容易得多.
