梅馨嫣栀 » 两个简单的Python自动登录脚本

文章目录

1 简介

自动登录脚本在一些需要频繁登录场景中非常有用，之前上学的时候用过中国联通wifi自动重连的一个脚本（Github传送门），感觉非常好用，点赞！

这里的简单登录脚本主要通过Python调用Selenium WebDriver的API进行实现，对于验证码自动识别这里主要借助前不久开放的百度AI的文字识别功能。

Selenium 是Thoughtworks推出的一个web自动化测试框架，WebDriver可以驱动Firefox、Chrome、IE、Edge、Safari等多种浏览器，Selenium通过 WebDriver驱动与浏览器进行交互。
百度AI之文字识别：支持多场景下的文字检测识别，中英混合识别，整体识别准确率高达90%以上。详细请访问百度OCR的官方介绍。

环境准备：

安装Selenium：

pip install selenium

1	pip install selenium

下载webdriver驱动：

Chrome:	https://sites.google.com/a/chromium.org/chromedriver/downloads
Edge:	https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
Firefox:	https://github.com/mozilla/geckodriver/releases
IE:	https://npm.taobao.org/mirrors/selenium/3.4/

百度AI OCR SDK下载安装：

http://ai.baidu.com/sdk#sdk-category-ocr

python setup.py build
python setup.py install

1 2	python setup.py build python setup.py install

一个简单的登录VPN的例子，驱动IE浏览器，首先经过https非安全证书确认。

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

driver = webdriver.Ie('C:\Program Files\IEDriverServer_Win32_3.4.0\IEDriverServer.exe')
driver.get("https://XXX.XXX.XXX.XXX/ssl/user/auth/home")

# 确认进入不安全的链接
elem_click = driver.find_element_by_name("overridelink")
elem_click.click();

# 用户名 密码
elem_user = driver.find_element_by_name("account")
elem_user.send_keys("name")
elem_pwd = driver.find_element_by_name("password")
elem_pwd.send_keys("youneverguess")
elem_pwd.send_keys(Keys.RETURN)
time.sleep(5)
assert "SSLVPN" in driver.title
driver.close()
driver.quit()

#!/usr/bin/env python

# -*- coding: utf-8 -*-

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

import time

driver = webdriver.Ie('C:\Program Files\IEDriverServer_Win32_3.4.0\IEDriverServer.exe')

driver.get("https://XXX.XXX.XXX.XXX/ssl/user/auth/home")

# 确认进入不安全的链接

elem_click = driver.find_element_by_name("overridelink")

elem_click.click();

# 用户名密码

elem_user = driver.find_element_by_name("account")

elem_user.send_keys("name")

elem_pwd = driver.find_element_by_name("password")

elem_pwd.send_keys("youneverguess")

elem_pwd.send_keys(Keys.RETURN)

time.sleep(5)

assert "SSLVPN" in driver.title

driver.close()

driver.quit()

一个自动识别验证码的登录例子，验证码图片是通过截图获取，然后调用百度AI开放平台的文字识别功能，然后进行自动登录。

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from PIL import Image,ImageEnhance
from aip import AipOcr

driver = webdriver.Chrome('C:\Program Files (x86)\chromedriver_win32\chromedriver.exe')
driver.get("http://XXXXXXXXXXXXX/login.html")

# 验证码截图
snap_image = 'D:\shotsnap.png'
code_image = 'D:\image_code.png'
driver.get_screenshot_as_file(snap_image)
im = Image.open(snap_image)
box = (1120,470,1230,507)
region = im.crop(box)
#region.show()
region.save(code_image)

# 百度开发者信息
APP_ID = '*****'
API_KEY = 'XXXXXXXXXXXXX'
SECRET_KEY = 'XXXXXXXXXXXXXXXX'

# 读取验证码文件
def get_file_content(filePath):
    with open(filePath, 'rb') as fp:
        return fp.read()

# 百度OCR识别验证码
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
result = aipOcr.basicGeneral(get_file_content(code_image))
code = result.get(u'words_result')[0].get(u'words')
print code

# 自动登录
elem_user = driver.find_element_by_id("tbxUserName")
elem_user.send_keys("XXXXXXXXXXXXXXXXXX")
elem_pwd = driver.find_element_by_id("tbxPassword")
elem_pwd.send_keys("XXXXXXXXXXXXXXXXXXXX")
elem_verify_code = driver.find_element_by_id("tbxCaptcha")
elem_verify_code.send_keys(code)
elem_pwd.send_keys(Keys.RETURN)
time.sleep(5)
assert "baidu" in driver.title
driver.close()
driver.quit()

#!/usr/bin/env python

# -*- coding: utf-8 -*-

import time

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

from PIL import Image,ImageEnhance

from aip import AipOcr

driver = webdriver.Chrome('C:\Program Files (x86)\chromedriver_win32\chromedriver.exe')

driver.get("http://XXXXXXXXXXXXX/login.html")

# 验证码截图

snap_image = 'D:\shotsnap.png'

code_image = 'D:\image_code.png'

driver.get_screenshot_as_file(snap_image)

im = Image.open(snap_image)

box = (1120,470,1230,507)

region = im.crop(box)

#region.show()

region.save(code_image)

# 百度开发者信息

APP_ID = '*****'

API_KEY = 'XXXXXXXXXXXXX'

SECRET_KEY = 'XXXXXXXXXXXXXXXX'

# 读取验证码文件

def get_file_content(filePath):

with open(filePath, 'rb') as fp:

return fp.read()

# 百度OCR识别验证码

aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)

result = aipOcr.basicGeneral(get_file_content(code_image))

code = result.get(u'words_result')[0].get(u'words')

print code

# 自动登录

elem_user = driver.find_element_by_id("tbxUserName")

elem_user.send_keys("XXXXXXXXXXXXXXXXXX")

elem_pwd = driver.find_element_by_id("tbxPassword")

elem_pwd.send_keys("XXXXXXXXXXXXXXXXXXXX")

elem_verify_code = driver.find_element_by_id("tbxCaptcha")

elem_verify_code.send_keys(code)

elem_pwd.send_keys(Keys.RETURN)

time.sleep(5)

assert "baidu" in driver.title

driver.close()

driver.quit()

登录效果如下图：

百度文字识别部分也可以调用在线REST服务使用，省去了安装SDK的步骤，验证码图片噪声较多时，识别率会大大下降。

Hi,

I enjoyed your article on http://zjzone.cc/index.php/2017/08/08/yi-ge-jian-dan-di-python-zi-dong-deng-lu-jiao-ben/. I especially liked how lucid the article was.

I gather you have linked to http://selenium-python.readthedocs.io/ from that page.

Would you consider linking to us?

Here is our link – Selenium

I did be happy to share your page with our 30k Facebook/Twitter/Linkedin Followers.
