python用win32com模拟浏览器(pam也是一样的原理)

 # -*- coding:UTF-8 -*- #!/user/bin/env pythonimport win32com.clientfrom time import sleep loginurl='http://passport.cnblogs.com/login.aspx'loginouturl='http://passport.cnblogs.com/logout.aspx'username='XXX'password='XXX' ie = win32com.client.Dispatch("InternetExplorer.Application")    ie.Visible = 0  ie.Navigate(loginurl)    state = ie.ReadyState    print "打开登陆页面"    while 1:        state = ie.ReadyState        if state ==4:            break        sleep(1)print "页面载入完毕，输入用户名密码"    state = None ie.Document.getElementById("tbUserName").value=username    ie.Document.getElementById("tbPassword").value=password    ie.Document.getElementById("btnLogin").click()     while 1:        state = ie.ReadyState        print state        if state ==4 and str(ie.LocationURL) == "http://home.cnblogs.com/":            break    sleep(1)print "登陆成功" print '你的昵称是：'print ie.Document.getElementById('lnk_current_user').title #博客园只能登录一次，注销print '注销！'ie.Navigate(loginouturl)

还有一个是利用同样组件时间google搜索的：

#!/user/bin/env python# -*- coding: cp936 -*-import timefrom win32com.client import DispatchurlFileName = "urlFile.txt"outputFileName = "result.txt"outputFile = open(outputFileName, 'w')ie = Dispatch("InternetExplorer.Application")ie.visible = 1ie.navigate('http://www.google.com.hk')while (ie.ReadyState != 4):    time.sleep(1)print 'Ò³ÃæÔØÈëÍê½á'with open(urlFileName) as urlFile:    for url in urlFile:        url = url.strip()        ie.Document.forms[0].elements["q"].value="site:" + url        ie.Document.forms[0].submit()                while (ie.ReadyState != 4 or str(ie.LocationURL).find(url) == -1):            print str(ie.LocationURL)            time.sleep(1)        result = ie.Document.getElementById("ires").innerHTML        if len(result)>0:            print url, "recored"            outputFile.write(url + ":recored/n")        else:            print url, "not recored"            outputFile.write(url + ":not recored/n")outputFile.close()
