【一天一个Python小案例】Python登录教务系统（手动输入验证码）

因百度OCR直接识别验证码的话，识别率太低，暂时手动输入

#!/usr/bin/env python
# coding:utf-8
from selenium import webdriver
from PIL import Image
import  time

if __name__ == '__main__':
    browser = webdriver.PhantomJS()
    browser.get("http://bkjw.whu.edu.cn/")  # 你可以拿知乎，百度，等等测试
    browser.maximize_window()
    browser.save_screenshot("login.png")
    for n in range(1,5):
        element = browser.find_element_by_xpath('//img[@id="captcha-img%d"]'%n)  # 验证码所在的xpath路径
        # element = browser.find_element_by_xpath('//div[@style="height:34px;margin:5px 5px 5px 5px;float:left;"]')
        left = element.location['x']
        if left == 0:
            continue
        top = element.location['y']
        right = element.location['x'] + element.size['width']
        bottom = element.location['y'] + element.size['height']
        print((left, top, right, bottom))
        im = Image.open(r'login.png')  # 页面截屏
        im = im.crop((left, top, right, bottom))
        im.show()
        im.save('captcha.png')
        time.sleep(2)
        break

    pwd = input("captcha:")
    browser.find_element_by_id("qxftest").send_keys("***")
    browser.find_element_by_name("pwd").send_keys("***")
    browser.find_element_by_name("xdvfb").send_keys(pwd)
    browser.find_element_by_id("loginBtn").click()
    browser.save_screenshot("input.png")
    browser.close()
