正正网络: Message fields can be one of the following: optional: a well-formed message can have zero or one of this field (but not more than one). repeated: this field can be repeated any number of times (including zero) in a well-formed message. The order of the repeated values will be preserved. required: Do not use. Required fields are so problematic they were removed from proto3. Semantics for required field should be implemented at the application layer. When it is used, a well-formed message must have exactly one of this field.
