豆瓣网的模拟登陆

1.首先代码先安装selenium

pip install selenium

2.写代码

#coding=utf-8
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

driver = webdriver.PhantomJS()
driver.get("http://www.douban.com")
# 输入账号密码
driver.find_element_by_name("form_email").send_keys("********@***.com")
driver.find_element_by_name("form_password").send_keys("*****")

# 模拟点击登录
driver.find_element_by_xpath("//input[@class='bn-submit']").click()

# 等待3秒
time.sleep(3)

# 生成登陆后快照
driver.save_screenshot("douban.png")

with open("douban.html", "w") as file:
    file.write(driver.page_source)

driver.quit() 

这是会报一个错

UnicodeEncodeError: 'ascii' codec can't encode characters in position

不用担心，解决办法为：
在代码的前加上

#! /usr/bin/env python
#coding=gbk
import sys
reload(sys)
sys.setdefaultencoding( "utf-8" )

这是就可以拿到页面信息

整体代码

#! /usr/bin/env python
#coding=gbk
import sys
reload(sys)
sys.setdefaultencoding( "utf-8" )
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

driver = webdriver.PhantomJS()
driver.get("http://www.douban.com")
# 输入账号密码
driver.find_element_by_name("form_email").send_keys("[email protected]")
driver.find_element_by_name("form_password").send_keys("092744gd")

# 模拟点击登录
driver.find_element_by_xpath("//input[@class='bn-submit']").click()

# 等待3秒
time.sleep(3)

# 生成登陆后快照
driver.save_screenshot("douban.png")

with open("douban.html", "w") as file:
    file.write(driver.page_source)

driver.quit()

动手试试吧！
