这段代码是一个 Python Flask 应用程序中的两个路由函数。第一个函数 `verify_identity` 用于验证用户身份,需要传入用户名、短信验证码和面部图像编码作为参数。它会先检查用户名是否已知,如果不是则返回 False。然后它会验证短信验证码是否正确,如果不正确则返回 False。最后,它会比较传入的面部图像编码和已知面部图像编码是否相同,如果不同则返回 False,否则返回 True。
第二个函数 `pay` 用于处理支付请求,需要传入用户名、短信验证码和面部图像 URL 作为参数。首先它会下载面部图像并提取面部特征编码。然后它会调用 `verify_identity` 函数来验证用户身份。如果验证通过,它将执行支付操作并返回一个 JSON 响应,表示支付成功。否则,它将返回一个 JSON 响应,表示支付失败。

java.net.UnknownHostException: zxhc: zxhc: Name or service not known
This exception is thrown when the Java application is unable to resolve the hostname "zxhc" to an IP address. This can occur due to various reasons such as:
1. Incorrect hostname: The hostname provided in the code might be incorrect.
2. DNS resolution failure: The DNS server might be unreachable or not responding.
3. Network connectivity issues: The application might not have network connectivity to resolve the hostname.
To resolve this issue, you can try the following:
1. Check the hostname: Verify that the hostname provided in the code is correct.
2. Check DNS resolution: Try pinging the hostname from the command line to see if it resolves to an IP address. If not, try using a different DNS server.
3. Check network connectivity: Verify that the application has network connectivity and can access the DNS server.
def login(username, password): # 根据用户名查找用户 user = User.find(username) if user is None: return False, 'User not found.' # 验证密码是否正确 if not user.verify_password(password): return False, 'Invalid password.' # 保存登录信息 session['username'] = username session['role'] = user.role return True, 'Login success.'
这段代码是一个登录函数,它接收用户名和密码作为参数。函数首先调用 User 类的 find 方法查找用户,如果用户不存在则返回错误信息。如果用户存在,函数会调用该用户的 verify_password 方法验证密码是否正确,如果密码不正确则返回错误信息。如果密码验证成功,函数会在 session 中保存用户名和用户角色信息,并返回登录成功的信息。需要注意的是,这段代码中的 User 类和 session 对象并没有被定义,你需要在代码中定义它们。
