首先，我们需要获取验证码验证过程所需的参数，包括as、ds和tk。这些参数可以通过请求获取。
python Copy code def get_verification_parameters(): url = "https://passport.baidu.com/viewlog" params = { "callback": "jQuery110205449684422426735_" + str(int(time.time() * 1000)), "ak": "33c48884b7df83d4230e07cbcd0d07fd", "_": str(int(time.time() * 1000)) } response = session.get(url, headers=headers, params=params) res_data = re.findall(r'.?({.?}))', response.text)[0] res_data = json.loads(res_data) parameters = { "tk": res_data['data']['tk'], "as": res_data['data']['as'], "ds": res_data['data']['ds'] } return parameters 获取验证码图片 然后，我们需要获取验证码图片，并解析其中的内容。
python Copy code def get_verification_image(parameters): url = "https://passport.baidu.com/viewlog/getstyle" params = { "callback": "jQuery110205449684422426735_" + str(time.time() * 1000), "ak": '3de47787fd60b30420f868ffbf4dbccd', "tk": parameters["tk"], "isios": "0", "type": "spin", "_": str(time.time() * 1000) } response = session.get(url, headers=headers, params=params) ret_data = re.findall(r'.?({.?}))', response.text)[0] ret_data = json.loads(ret_data) verification_image = { "image_url": unquote(ret_data['data']['ext']['img']), "backstr": ret_data['data']['backstr'], "tk": parameters["tk"], "as": parameters["as"] } response = session.get(verification_image['img_url'], verify=False) with open('verification_image.png', 'wb')as f: f.write(response.content) return verification_image 打码 我们将获取到的验证码图片提交给打码平台进行识别。
python Copy code def solve_captcha(verification_image): with open('verification_image.png', 'rb') as f: image_content = f.read() image_b64 = base64.b64encode(image_content) # 调用打码API captcha_solution = dama_api(image_b64) verification_image['angle'] = captcha_solution return verification_image 验证 最后，我们将获取到的验证结果提交给百度服务器进行验证。
python Copy code def verify_captcha(verification_image): url = "https://passport.baidu.com/viewlog" fs = build_fs(int(verification_image['angle']), verification_image['as'], verification_image['backstr']) params = { "callback": "jQuery110204100787474351779_" + str(time.time() * 1000), "ak": "3de47787fd60b30420f868ffbf4dbccd", "as": verification_image['as'], "fs": fs, "tk": verification_image['tk'], "cv": "submit", "_": str(time.time() * 1000) } response = session.get(url, headers=headers, params=params) ret_data = re.findall(r'.?({.?}))', response.text)[0] ret_data = json.loads(ret_data) return ret_data 主函数 将上述步骤整合到主函数中。
python Copy code def main(): parameters = get_verification_parameters() verification_image = get_verification_image(parameters) verification_image = solve_captcha(verification_image) verification_result = verify_captcha(verification_image) if verification_result['data']['op'] == 1: print("验证通过") else: print("验证失败")
if name == "main": main() 更多内容联系q1436423940
