一、.proto文件字段概述

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map<int32,string> attributes = 4;map<int32,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;
}

// 接口服务定义protofield.proto文件syntax = "proto3";import "google/protobuf/empty.proto";
import "Protos/datamessages.proto";option csharp_namespace = "GrpcProject";package grpc.serviceing;service FieldRpc{// 基础字段处理rpc BaseConfigService(BaseConfig) returns (google.protobuf.Empty);// 日期字段处理rpc DateConfigService(DateConfig) returns (google.protobuf.Empty);// 字节处理rpc ByteConfigService(ByteConfig) returns (google.protobuf.Empty);// null字段处理rpc NullConfigService(NullConfig) returns (google.protobuf.Empty);// 集合类型字段处理rpc ListConfigService(ListConfig) returns (google.protobuf.Empty);// 任意类型字段处理rpc AnyConfigService(AnyConfig) returns (google.protobuf.Empty);// Oneof类型字段处理rpc OneofConfigService(OneofConfig) returns (google.protobuf.Empty);

三、客户端定义

引用proto文件，配置为客户端类型
根据编译生成的函数进行传参调用
创建WPF测试客户端
各个服务接口创建对应的按钮进行调用
执行过程中，服务端控制台会打印对应的消息

        // 基础private async void BtnBaseconfig_Click(object sender, RoutedEventArgs e){await WpfFieldClient.Show(1);MessageBox();}// 日期private async void BtnDateconfig_Click(object sender, RoutedEventArgs e){await WpfFieldClient.Show(2);MessageBox();}// 字节private async void BtnByteconfig_Click(object sender, RoutedEventArgs e){await WpfFieldClient.Show(3);MessageBox();}// nullprivate async void BtnNullconfig_Click(object sender, RoutedEventArgs e){await WpfFieldClient.Show(4);MessageBox();}// listprivate async void BtnListconfig_Click(object sender, RoutedEventArgs e){await WpfFieldClient.Show(5);MessageBox();}// anyprivate async void BtnAnyconfig_Click(object sender, RoutedEventArgs e){await WpfFieldClient.Show(6);MessageBox();}// Oneofprivate async void BtnOneofconfig_Click(object sender, RoutedEventArgs e){await WpfFieldClient.Show(7);MessageBox();}

调用的类库：

    public class WpfFieldClient{/// <summary>/// 根据参数选择不同的方法执行/// </summary>/// <param name="k"></param>public static async Task Show(int k){var channel = GrpcChannel.ForAddress("https://localhost:7188");var client = new GrpcProject.FieldRpc.FieldRpcClient(channel);// 基础BaseConfig config = new BaseConfig();config.Name = "张三";config.Position = 2.33D;config.Distance = 5.48F;config.Age = 10;config.TimeSpanId = 6538590027736100;config.SAge = 1921;config.STimeSpanId = 6538590027736130;config.Flag = true;// 日期DateConfig dateConfig = new DateConfig();dateConfig.Id = 179;dateConfig.DateDuration = Duration.FromTimeSpan(TimeSpan.FromSeconds(5));// 注意这里的时间是utc时间dateConfig.DateTimestamp = Timestamp.FromDateTime(DateTime.UtcNow);// 字节ByteConfig byteConfig = new ByteConfig();byteConfig.Id = 9854564654654;byteConfig.PositionBytes = ByteString.CopyFrom(Encoding.UTF8.GetBytes("庄这人的南的很"));// nullNullConfig nullConfig = new NullConfig();nullConfig.Id = 1854564654654;nullConfig.NullBool = true;nullConfig.NullFloat = null;nullConfig.NullUInt = null;nullConfig.NullInt = 15;nullConfig.NullLong = 112345451234787;// ListConfigListConfig listConfig = new ListConfig();var attributes = new Dictionary<int, string>{[1] = "one",[2] = "two",[3] = "three",[4] = "four",[5] = "five"};listConfig.Id = 123456456;listConfig.Attributes.Add(attributes);var dicDetail = new Dictionary<int, ListDetailConfig>{[1] = new ListDetailConfig { Height = 1, Name = "one" },[2] = new ListDetailConfig { Height = 2, Name = "two" },[3] = new ListDetailConfig { Height = 3, Name = "three" },[4] = new ListDetailConfig { Height = 4, Name = "four" },[5] = new ListDetailConfig { Height = 5, Name = "five" }};listConfig.DicDetail.Add(dicDetail);listConfig.Details.Add(new ListDetailConfig { Height = 8, Name = "Eight" });var detailConfigs = new List<ListDetailConfig>{new ListDetailConfig { Height=9,Name="nine"},new ListDetailConfig{ Height=10,Name="ten"}};listConfig.Details.Add(detailConfigs);// AnyAnyConfig anyConfig = new AnyConfig();anyConfig.Id = 42564134;anyConfig.AnyObject = Any.Pack(new B { Id = 15 });// OneofOneofConfig oneofConfig = new OneofConfig();oneofConfig.OA = new A { Id = 1 };//oneofConfig.OC = new C { Id = 2 };var emptyResult = k switch{1 => await client.BaseConfigServiceAsync(config),2 => await client.DateConfigServiceAsync(dateConfig),3 => await client.ByteConfigServiceAsync(byteConfig),4 => await client.NullConfigServiceAsync(nullConfig),5 => await client.ListConfigServiceAsync(listConfig),6 => await client.AnyConfigServiceAsync(anyConfig),7 => await client.OneofConfigServiceAsync(oneofConfig),_ => new Empty()};}}
