利用python,可以实现填充网页表单,从而自动登录web门户。
(注意:以下内容只针对python3)
环境准备:
(1)安装python
(2)安装splinter,下载源码 python setup install
#coding=utf-8 import time from splinter import browser def login_mail(url): browser = browser() #login 163 email websize browser.visit(url) #wait web element loading #fill in account and password browser.find_by_id('username').fill('你的用户名称') browser.find_by_id('password').fill('你的密码') #click the button of login browser.find_by_id('loginbtn').click() time.sleep(5) #close the window of brower browser.quit() if __name__ == '__main__': mail_addr ='http://reg.163.com/' login_mail(mail_addr)
tips:
(1)如果需要修改web的html属性,可以使用:js
browser.execute_script('document.getelementbyid("html属性id").value = "在此提供默认值"')
(2)browser = browser()
不指定的情况下,浏览器驱动是火狐(firefox),可以指定其他:browser = browser(‘chrome'),需要下载对应的驱动程序
1.python3浏览页面
#coding=utf-8 import urllib.request import time #在请求加上头信息,伪装成浏览器访问 headers = {'user-agent':'mozilla/5.0 (windows nt 6.1; wow64; rv:23.0) gecko/20100101 firefox/23.0'} chaper_url='http://xxx' vist_num=1 while vist_num<1000: if vist_num%50==0: time.sleep(5) print("this is the 【 "+str(vist_num)+" 】次尝试") req = urllib.request.request(url=chaper_url, headers=headers) urllib.request.urlopen(req).read() #.decode('utf-8') vist_num+=1
2.python 多线程
#coding=utf-8 import threading #导入threading包 from time import sleep import time def fun1(): print ("task 1 executed." ) time.sleep(3) print ("task 1 end." ) def fun2(): print ("task 2 executed." ) time.sleep(5) print ("task 2 end." ) threads = [] t1 = threading.thread(target=fun1) threads.append(t1) t2 = threading.thread(target=fun2) threads.append(t2) for t in threads: # t.setdaemon(true) t.start()
3.利用python下载百度图片
#coding=utf-8 import urllib.request import re def gethtml(url): page = urllib.request.urlopen(url) html = page.read() return html def getimg(html): reg = r'src="(.+?\.jpg)"' imgre = re.compile(reg) html=html.decode('utf-8') imglist = re.findall(imgre,html) x = 0 for imgurl in imglist: urllib.request.urlretrieve(imgurl,'%s.jpg' % x) x+=1 print(str(x)) html = gethtml("http://image.baidu.com/channel?c=%e6%91%84%e5%bd%b1&t=%e5%85%a8%e9%83%a8&s=0") print(getimg(html))
