回到顶部一、简介
简单解析一下gRPC，gRPC 是一个由Google开源的，跨语言的，高性能的远程过程调用（RPC）框架。
特点：
[*]跨语言
[*]内容protobuf格式（比json体积小）,网络传输快
[*]使用HTTP/2进行传输
适合高性能轻量的微服务，一般对外的接口用restful api，内部服务的调用用gRPC。gRPC是一个分布式服务框架，和以前的WebService，WCF类似。
回到顶部二、创建gRPC服务端
1.创建gRPC项目
新建一个gRPC模板的项目
特别的地方就这里4点。
1.基于http2来通信。
2.proto协议文件，greet.proto是项目默认给我们的一个hello world的示例。它会根据协议自动生成需要的类。
3.服务类，Greeter.GreeterBase来自于2中的proto文件自动生成的类，生成的类在\obj\Debug\net6.0\Protos 目录下。
自动生成的类：
4.Program.cs添加了gRPC服务，和把GreeterService注册到管道中。
2.编写自己的服务
怎么样写自己的调用服务呢？
1.创建proto文件
参照上面的示例创建自己的Proto文件
代码:
syntax = "proto3";
option csharp_namespace = "GrpcDemo.Service";
package order;
// 订单服务定义
service Order {
// 创建订单
rpc CreateOrder (CreateRequest) returns (CreateResult);
//查询订单
rpc QueryOrder (QueryRequest) returns (QueryResult);
}
//创建订单请求参数
message CreateRequest {
string orderNo = 1;
string orderName=2;
double price=3;
}
//创建订单返回结果
message CreateResult {
bool result = 1;
string message=2;
}
//查询订单请求参数
message QueryRequest{
string id=1;
}
//查询订单返回结果
message QueryResult{
string id=1;
string orderNo=2;
string orderName=3;
double price=4;
}
生成一下就能看到对应的类已经生成了。
2.实现定义的服务
创建OrderService.cs
public class OrderService:Order.OrderBase
{
<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />private readonly ILogger<GreeterService> _logger;
<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />

<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />}
}继承的Order.OrderBase 是上面的proto文件生成的，然后实现了proto里面定义的两个服务。
然后在program.cs里面把服务注入管道。
到这里服务端就完成了，就可以启动服务端了。
浏览器访问不了，要通过gRPC客户端才能访问，下面就建一个gRPC客户端。
回到顶部三、创建gRPC客户端
1.创建客户端项目
1.1、这里创建一个控制台程序。
1.2、然后添加Nuget包
Google.Protobuf
Grpc.Net.Client
Grpc.Tools<br>Grpc.Net.clientFactory1.3、把服务端的proto文件拷贝过来
1.4、编辑项目文件，把proto里面的内容替换掉，默认是服务端的配置
<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />生成的时候，客户端也生成了对应proto的类
2.grPC服务https的调用
因为服务端提供了http和https的端口，这里先调用https的
创建GrpcRequestTest.cs类
/// /// gRPC请求测试 /// public class GrpcRequestTest {<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />public void CreateOrder()<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />{<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> //常规使用，https<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> string url = "https://localhost:7246";<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> using(var channel=GrpcChannel.ForAddress(url))<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> {<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />var client = new Order.OrderClient(channel);<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />var reply = client.CreateOrder(new CreateRequest()<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />{<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> OrderNo = DateTime.Now.ToString("yyyMMddHHmmss"),<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> OrderName = "冰箱22款",<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> Price = 1688<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />});<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />Console.WriteLine($"结果:{reply.Result},message:{reply.Message}");<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> }<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> Console.ReadKey();<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />} }结果：
3.gRPC内网http调用
public void CreateOrder()<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />{<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> //使用http<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />

<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> string url = "http://localhost:5246";<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> using(var channel=GrpcChannel.ForAddress(url))<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />

<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />var client = new Order.OrderClient(channel);<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />var reply = client.CreateOrder(new CreateRequest()<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" /><Protobuf Include="Protos\greet.proto" GrpcServices="Client" />

<Protobuf Include="Protos\order.proto" GrpcServices="Client" />}比起https，前面多了一行。结果：
4.IOC注入的方式调用gRPC
4.1、program.cs里面注入gRPCClient
// See https://aka.ms/new-console-template for more information
using GrpcDemo.Client;
using GrpcDemo.Service;
using Microsoft.Extensions.DependencyInjection;
Console.WriteLine("Hello, World!");
IServiceCollection services = new ServiceCollection();
services.AddTransient<GrpcRequestTest>();
#region gRPC Client注册
AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);
services.AddGrpcClient<Order.OrderClient>(options =>
{
options.Address = new Uri("http://localhost:5246");
}).ConfigureChannel(grpcOptions =>
{
//可以完成各种配置，比如token
});
#endregion
//构建容器
IServiceProvider serviceProvider = services.BuildServiceProvider();
//解析grpc请求测试
var grpcRequestTest = serviceProvider.GetService<GrpcRequestTest>();
//执行
grpcRequestTest.CreateOrder();grpcRequestTest里代码：

回到顶部四、webapi中加入gRPC
通常我们的服务有对外提供对外接口，又要对内提供gRPC服务，那怎么做呢，下面在webapi中加入gRPC服务
1.创建asp.net core mvc项目
2.安装nuget包
Grpc.AspNetCore3.添加protebuf文件
把上面的proto文件复制过来
4.添加Service

<Protobuf Include="Protos\order.proto" GrpcServices="Client" /> });<Protobuf Include="Protos\greet.proto" GrpcServices="Client" />
<Protobuf Include="Protos\order.proto" GrpcServices="Client" />} }5.注册gRPC服务
在Program.cs文件中
到这里，就把gRPC加入到webapi里面了。
6.验证
启动asp.net core mvc程序
浏览器能访问，证明 restful api是没问题的。
然后再用上面的客户端访问一下gRPC的服务。
结果：
这样就成功对外提供api接口和对内提供gRPC服务了。
