grpc的接口传输参数都是根据.proto文件约定的字段格式进行传输的grpc提供了多种类型字段主要包括标量值类型基础类型、日期时间、可为null类型、字节、列表、字典、Any类型任意类型、Oneof等字段严格规范是一种强类型文件协议
二、案例介绍
标量值类型日期时间可为null类型字节列表字典Any类型Oneof一种语言特性可以通过该特性进行对象切换处理使用 oneof 指定可能返回 A对象或B对象 的响应消息
三、服务端定义
定义通用消息实体根据不同的类型创建对应的案例实体特殊的字段需要导入指定的包才能使用定义引用字段的各个服务接口内部实现逻辑及打印展示相应的字段结果
// 1.提供公共的实体proto文件
// 2.服务引用对应的proto文件// 通用消息文件datamessages.proto
syntax proto3;option csharp_namespace GrpcProject;package grpc.serviceing;// 基础类型实体
message BaseConfig{string name 1;double position 2;float distance 3 ;int32 age 4;int64 timeSpanId 5;uint32 uAge 6;uint64 uTimeSpanId 7;sint32 sAge 8;sint64 sTimeSpanId 9;bool flag 10;
}// 日期类型实体 需要导入 日期namespace
import google/protobuf/duration.proto;
import google/protobuf/timestamp.proto;message DateConfig{int64 id 1;google.protobuf.Timestamp dateTimestamp 2;google.protobuf.Duration dateDuration 3;
}// 字节类型
message ByteConfig{int64 id 1;bytes positionBytes 2;
}// 可为null类型 需要导入 null的namespace
import google/protobuf/wrappers.proto;message NullConfig{int64 id 1;google.protobuf.BoolValue nullBool 2;google.protobuf.DoubleValue nullDoubule 3;google.protobuf.FloatValue nullFloat 4;google.protobuf.Int32Value nullInt 5;google.protobuf.Int64Value nullLong 6;google.protobuf.UInt32Value nullUInt 7;google.protobuf.StringValue nullString 8;google.protobuf.BytesValue nullBytes 9;
}// 集合类型
message ListConfig{int64 id 1;// 数组repeated string names 2;repeated ListDetailConfig details 3;// 字典mapint32,string attributes 4;mapint32,ListDetailConfig dicDetail 5;
}message ListDetailConfig{string name 1;int32 height 2;
}// 任意类型 需要导入对应的包
import google/protobuf/any.proto;
message AnyConfig{int32 id 1;google.protobuf.Any anyObject 2;
}// Oneof类型 编译器在生成消息类时处理 oneof 关键字。 使用 oneof 指定可能返回 A 或 B 或 C 的响应消息
message OneofConfig{oneof result{A oA 1;B oB 2;C oC 3;}
}message A{int32 id 1;
}message B{int32 id 1;
}message C{int32 id 1;
