前言

第一次建立GRPC服务端，客服端一直通不到服务端；
问题1：

One or more errors occurred. (Status(StatusCode=Internal, Detail="Error starting gRPC call. HttpRequestException: The SSL connection could not be established, see inner exception. IOException: The handshake failed due to an unexpected packet format."))
Status(StatusCode=Internal, Detail="Error starting gRPC call. HttpRequestException: The SSL connection could not be established, see inner exception. IOException: The handshake failed due to an unexpected packet format.")

问题2：

One or more errors occurred. (Status(StatusCode="Unimplemented", Detail="Bad gRPC response. HTTP status code: 404"))
Status(StatusCode="Unimplemented", Detail="Bad gRPC response. HTTP status code: 404")

一、问题一解决方法

原因：

gRPC默认内置了两种认证方式：
SSL/TLS认证方式
基于Token的认证方式

服务端建立https即可

二、问题二解决方法

原因是因为服务端没有注册成功GRPC

1.需要配置GRPC，在ConfigureServices方法中

//1.配置grpc
services.AddGrpc();

2.开启GRPC,在ConfigRoute方法中

 app.UseEndpoints(endpoints =>{//2开启Grpcendpoints.MapGrpcService<GisPointDeviceServiceImpl>();endpoints.MapControllers();});

GisPointDeviceServiceImpl，是对应的服务

3. 第三步在报错前是已经做过的；

在ConfigureProduction方法中加入以下代码

string address = Environment.GetEnvironmentVariable("TSPSERVER_ADDRESS", EnvironmentVariableTarget.Process);
app.UseConsul(address, "GIS", address);
string grpcAddress = Environment.GetEnvironmentVariable("TSPGRPC_ADDRESS", EnvironmentVariableTarget.Process);
app.UseConsul(grpcAddress, "GISGrpc", address);
