1.通过定位元素截取图片的方法进行识别

#ocr识别原理：先根据验证码的class dl_yzm定位到验证码图片，然后将验证码截图保存，再使用ocr进行识别，读取出来验证码，填充到yzm_text中（使用IE浏览器不可用）

driver.find_element(By.CLASS_NAME, "dl_yzm").click()

yzmImage=driver.find_element(By.XPATH,"/html/body/div[@class='login_bg']/div[@class='login_main']/div[@class='login_box']/p[4]/span[@class='dl_yzm']/img/@src")#验证码图片

yzmImage.screenshot("yzm.png")#验证码截图，存为yzm.png

ocr=ddddocr.DdddOcr()(show_ad=False)

with open("yzm.png","rb") as fp:

image=fp.read()

catch=ocr.classification(image)#验证码返回给catch

print(catch)

driver.find_element(By.ID,"yzm_text").send_keys(catch)#将ocr识别出的验证码填到yzm_text

2.#另外一种办法通过坐标的方式截取验证码图片并识别

#截取当前页面

driver.save_screenshot('web_screen.png')

page_snap_obj=Image.open('web_screen.png')

#定位验证码

yzm=driver.find_element(By.CLASS_NAME,"dl_yzm")

location=yzm.location

size=yzm.size

left=location['x']

top=location['y']

right=left+size['width']

bottom=top+size['height']

yzm_obj=page_snap_obj.crop((left,top,right,bottom))

#保存截取的验证码图片，并识别验证码内容

yzm_obj.save('yzm.png')

ocr=ddddocr.DdddOcr(show_ad=False)

with open('yzm.png','rb') as fp:

img=fp.read()

catch=ocr.classification(img)

driver.find_element(By.ID, "yzm_text").send_keys(catch) # 将ocr识别出的验证码填到yzm_text
