package tutorial;
message Person {
required string name = 1;
required int32 id = 2;
optional string email = 3;

“1”、“2”、“3”是什么意思？
最佳答案
Each field in the message definition has a unique numbered tag. These tags are used to identify your fields in the message binary format, and should not be changed once your message type is in use.
