selenium学习笔记13-解决验证码问题

方案一:使用pytesseract和pillow实现验证码识别

可以使用pytesseract 模块和 PIL模块解决不太复杂的验证码问题,实现步骤如下:

1、安装pytesseract     -》pip install pytesseract 

2、安装PIL模块   -》pip install pil

仅可识别简单的验证码

代码如下:

import time

from selenium import webdriver
from PIL import Image
import pytesseract
import unittest


def test1():
    #打开谷歌浏览器
    browser = webdriver.Chrome()
    #打开首页
    browser.get("http://localhost:8080/jpress/user/register")
    browser.maximize_window()

    #获取验证码图片
    t = time.time()
    picture_name1 = str(t)+'.png'
    browser.save_screenshot(picture_name1)

    ce = browser.find_element_by_id("captchaimg")
    print(ce.location)
    left = ce.location['x']
    top = ce.location['y']
    right = ce.size['width'] + left
    height = ce.size['height'] + top

    im = Image.open(picture_name1)
    # 抠图
    img = im.crop((left,top,right, height))

    t = time.time()
    picture_name2 = str(t)+'.png'

    img.save(picture_name2)#这里就是截取到的验证码图片
    browser.close()


def test2():
    image1 = Image.open('test.png')
    str = pytesseract.image_to_string(image1)
    print(str)

 

 

方案二:通过第三方AI库识别验证码

对于复杂的验证码,可以使用第三方的api来实现,万维易源的API来解决验证码问题,网址是:https://www.showapi.com/

识别验证码的地址是:https://www.showapi.com/apiGateway/view?apiCode=184

代码如下:

from lib.ShowapiRequest import ShowapiRequest

def test01():
    r = ShowapiRequest("http://route.showapi.com/184-4","547473","741edd63a66b44159bfd7f7bb23ce60a" )
    r.addFilePara("image", "test.png")
    r.addBodyPara("typeId", "34")
    r.addBodyPara("convert_to_jpg", "0")
    r.addBodyPara("needMorePrecise", "0")
    res = r.post()
    result = res.text
    print(result)
    body = res.json()['showapi_res_body']
    print(body['Result'])
# print(res.text) # 返回信息
