一、百度OCR文字识别云服务

百度云-产品-搜索：文字识别-通用场景文字识别-立即使用-开通（实名认证）-免费尝鲜-创建新应用-调用服务-通用场景文字识别（高精度版）-复制相关代码

需要终端安装base64:pip install pybase64

python 复制代码 
import requests
import base64

host = 'https://aip.baibubce.com/pauth/2.0/token?grant_type=client_credentials&client_id=[官网获取的AK]&client_secret=[官网获取的SK]'
response = requests.get(host)
if response:
    access_token = reponse.json()["access_token"]
    print(access_token)

request_url = "https://aip.baidubce.com/rest/2.0/ocr/v1/accurate_basic"
# 二进制方式打开图片文件
f = open('[本地文件]', 'rb')
img = base64.b64encode(f.read())

params = {"image":img}
# access_token = '[调用鉴权接口获取的token]'
request_url = request_url + "?access_token=" +access_token
headers = {'content-type': 'application/x-www-form-urlencoded'}
response = requests.post(request_url, data=params, headers=headers)
if response:
    print(response.json()["words_result"][0]["words"])

thresh, back = cv2.threshold(back, 110, 255, cv2.THRESH_BINARY)
thresh, front = cv2.threshold(front, 40, 255, cv2.THRESH_BINARY_INV)

cv2.imwrite('./img2/back2.png', back)
cv2.imwrite('./img2/front2.png', front)

match = cv2.matchTemplate(back, front, cv2.TM_CCORR_NORMED)
distance = cv2.minMaxLoc(match)[3][0]
print(distance)

# cv2.imshow("back", back)
# cv2.imshow("front", front)

# cv2.waitKey(0)
# cv2.destroyAllWindows()

    match = cv2.matchTemplate(back, front, cv2.TM_CCORR_NORMED)
    distance = cv2.minMaxLoc(match)[3][0]
    # 341:滑动验证码图片的长， 680：下载后图片的长， 37：滑块现在距离滑动验证码图片最左端的距离
    distance = distance * 341 // 680 - 37
    print(distance)

    slider = driver.find_element(By.XPATH, '//*[@id="tcaptcha_drag_thumb"]')
    ActionChains(driver).pause(0.2).click_and_hold(slider).pause(0.2).move_by_offset(distance / 4, 5).perform()   
    ActionChains(driver).pause(0.1).move_by_offset(distance / 2, -2).perform()
    ActionChains(driver).pause(0.1).move_by_offset(distance / 4, 3).release().perform()
