验证码处理：

- 1.手动识别验证码

- 2.云打码平台自动识别验证码

云打码平台处理验证码的实现流程：

- 1.对携带验证码的页面数据进行抓取

- 2.可以将页面数据中验证码进行解析，验证码图片下载到本地

- 3.可以将验证码图片提交给三方平台进行识别，返回验证码图片上的数据值

- 云打码平台：

- 1.在官网中进行注册(普通用户和开发者用户)

- 2.登录开发者用户：

- 1.实例代码的下载(开发文档-》调用实例及最新的DLL-》PythonHTTP实例下载)

- 2.创建一个软件：我的软件-》添加新的软件

-3.使用示例代码中的源码文件中的代码进行修改，让其识别验证码图片中的数据值

云打码普通用户

#该函数就调用了打码平台的相关的接口对指定的验证码图片进行识别，返回图片上的数据值

def getCode(codeImg):

# 云打码平台普通用户的用户名

username = '用户'

# 云打码平台普通用户的密码

password = '密码'

# 软件ＩＤ，开发者分成必要参数。登录开发者后台【我的软件】获得！

appid = 6003

# 软件密钥，开发者分成必要参数。登录开发者后台【我的软件】获得！

appkey = 'xxxxxxxxxxx'

# 验证码图片文件

filename = codeImg

# 验证码类型，# 例：1004表示4位字母数字，不同类型收费不同。请准确填写，否则影响识别率。在此查询所有类型 http://www.yundama.com/price.html

codetype = 3000

# 超时时间，秒

timeout = 20

# 检查

if (username == 'username'):

print('请设置好相关参数再测试')

else:

# 初始化

yundama = YDMHttp(username, password, appid, appkey)

# 登陆云打码

uid = yundama.login();

print('uid: %s' % uid)

# 查询余额

balance = yundama.balance();

print('balance: %s' % balance)

# 开始识别，图片路径，验证码类型ID，超时时间(秒)，识别结果

cid, result = yundama.decode(filename, codetype, timeout);

print('cid: %s, result: %s' % (cid, result))

return result
