When sending UDP packets, the ports must be handled as specified in the data definition.怎么理解

这句话的意思是，在发送UDP数据报时，必须按照数据定义中指定的方式来处理端口。也就是说，发送方必须按照数据定义中规定的端口号将数据报发送到目标端口。接收方则需要按照相同的端口号来接收和处理数据报。这是因为UDP是一种无连接协议，没有像TCP一样的连接状态来保证数据传输的可靠性，因此需要通过端口号来确定数据报的发送和接收方。不过，具体端口的处理方式可能会因协议和应用程序的不同而有所差异，因此需要按照相应的规定来处理。

The specified 'scope' is invalid. openddict

The error message "The specified 'scope' is invalid" usually occurs when the requested scope is not valid or does not exist in the authorization server.

To resolve this error, you can try the following steps:

1. Double-check the scope parameter in your authorization request and ensure that it matches the defined scopes in the authorization server.

2. Check if the requested scope is supported by the authorization server, as some servers might have limited scopes available.

3. If you are using a third-party library or SDK to make the authorization request, make sure that it is configured correctly and is sending the correct scope parameter.

4. If none of the above steps work, you may need to contact the authorization server administrator or consult their documentation for more information on supported scopes.

With Request/Response methods, the server must respond by sending an error message when an invalid message is received.翻译

使用请求/响应方法时，当服务器接收到无效消息时，必须通过发送错误消息来进行响应。在SOME/IP协议中，请求/响应方法用于客户端向服务器发送请求消息，并期望服务器响应相应的响应消息。当服务器接收到无效的请求消息时，必须向客户端发送错误消息来进行响应，以指示请求无效的原因。这可以确保请求的有效性和正确性，避免不必要的请求处理。
