部分python代码

result = cp.call('verifyPoint', result_track, points)
url = "captcha/v4/verify_icon"
data = {"appid": "","token": token,"rid": rid,"business_site": '',"version": "1.0.6","verify_msg": result['verify_msg'],"dimensions": dimensions,"extend_param": result['extend_param'],"sign": result['sign'],
}
data = json.dumps(data, separators=(',', ':'))
response = session.post(url, headers=headers, data=data, proxies=proxies)print(response.text)
result = json.loads(response.text)['result']
print(result)

result = cp.call('verifyPoint', result_track, points)
url = "captcha/v4/verify_icon"
data = {"appid": "","token": token,"rid": rid,"business_site": '',"version": "1.0.6","verify_msg": result['verify_msg'],"dimensions": dimensions,"extend_param": result['extend_param'],"sign": result['sign'],
}
data = json.dumps(data, separators=(',', ':'))
response = session.post(url, headers=headers, data=data, proxies=proxies)print(response.text)
result = json.loads(response.text)['result']
print(result)
