创建具有重复字段的 grpc 客户端请求

Question

我有这样的原型文件：message StartAssignmentRequest {  string additional_comment = 3;  repeated RideSlip slips = 4;}message RideSlip{  string slip_name = 2;  string slip_ext = 3;  string slip_link = 4;}现在我想创建它的请求，我正在做这样的事情：req := &api.StartAssignmentRequest{    AdditionalComment:"AdditionalComment",    Slips: &api.RideSlip[],}但不知道如何正确发送RideSlip数据。

Answer 1

Protobuffer（2 和 3）字段在 Go 中编译为切片。repeated

就这样：append

req := &api.StartAssignmentRequest{

    AdditionalComment: "AdditionalComment",

}

req.Slips = append(req.Slips, &api.RideSlip{

    SlipName: "foo",

    SlipExt: "bar",

    SlipLink: "https://stackoverflow.com",

})

或者为其分配一个文本值：

req := &api.StartAssignmentRequest{

    AdditionalComment: "AdditionalComment",

    Slips: []*api.RideSlip{

        {

            SlipName: "foo",

            SlipExt: "bar",

            SlipLink: "https://stackoverflow.com",

        },

    },

}
