如何在protobuf消息中添加一个int数组 [英] How to add a int array in protobuf message

问题描述

我必须编写一个 protobuf 消息，它应该有 1 个整数变量和一个整数数组.

I have to compose a protobuf message which should have 1 integer variables and a integer array.

package protobuf;

message myProto {

optional uint32 message_id =1;
optional int update = 2;
//here I have to add a array of integers
//can I write like     optional int[] array =3;
//or should I use      optional repeated array;
//where array is another message with int variable

}

我的方法正确吗?请帮帮我

Is my approach correct? Please help me

谢谢

推荐答案

数组通过重复"映射:

 repeated int32 data = 4;

请注意，您可能需要 sint32/uint32.还要注意，三种情况都可以使用打包数组"，效率更高；

Note you might want sint32/uint32. Also note that in all three cases "packed arrays" can be used, which are more efficient;

repeated int32 data = 4 [packed=true];
