安裝

go get -u github.com/envoyproxy/protoc-gen-validate

 使用方法：float order_money = 4[(validate.rules).float.gt = 1];

message OrderMain {
    int32 order_id = 1;
    string order_no = 2;
    int32 user_id = 3;
    float order_money = 4[(validate.rules).float.gt = 1];
    google.protobuf.Timestamp order_time = 5;
    repeated OrderDetail order_details = 6;
}

服務端驗證

err := request.OrderMain.Validate()
if err != nil {
   return &OrderResponse{
      Status:  "failed",
      Message: err.Error(),
   }, nil
}
