        }
        params.update(self.base_params)
        files = {'userfile': ('ccc.jpg', im)}
        r = requests.post('http://upload.chaojiying.net/Upload/Processing.php', data=params, files=files,headers=self.headers)
        return r.json()

    def ReportError(self, im_id):
        """
        im_id:报错题目的图片ID
        """
        params = {

        params.update(self.base_params)
        r = requests.post('http://upload.chaojiying.net/Upload/ReportError.php', data=params, headers=self.headers)
        return r.json()

if __name__ == '__main__':
    chaojiying = Chaojiying_Client('userName', 'password', 'appId')  # 用户中心>>软件ID 生成一个替换 96001
    im = open('./code.jpg', 'rb').read()  # 本地图片文件路径 来替换 a.jpg 有时WIN系统须要//
    print (chaojiying.PostPic(im, 1902))

headers={
    "User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.107 Safari/537.36 Edg/92.0.902.62",
}
url = 'http://www.chaojiying.com/user/login/'
page_text = requests.get(url=url,headers=headers).text
tree = etree.HTML(page_text)
img_url = 'http://www.chaojiying.com/'+tree.xpath('/html/body/div[3]/div/div[3]/div[1]/form/div/img/@src')[0]
img_data = requests.get(url= img_url,headers=headers).content
with open('./code.jpg','wb') as fp:
    fp.write(img_data)

结果显示

D:\网站的案例\pythonProject\venv\Scripts\python.exe D:/网站的案例/pythonProject/main.py
{'err_no': -1003, 'err_str': '用户名的密码出错', 'pic_id': '0', 'pic_str': '', 'md5': ''}

先检测超级鹰的登录状态，确定登录状态之后，在测试识别功能
