在C#中简单使用gRPC

一、引言

　　本文采用gRPC官方提供的一个教程例子，通过这个例子可以学习到在.proto文件中定义服务。使用protocol buffer编译器生成服务器和客户端代码。使用C＃gRPC API为您的服务编写简单的客户端和服务器。具体可参看：https://grpc.io/docs/tutorials/basic/csharp/

二、具体步骤

  • 定义.proto文件

syntax = "proto3";

option java_multiple_files = true;
option java_package = "io.grpc.examples.routeguide";
option java_outer_classname = "RouteGuideProto";
option objc_class_prefix = "RTG";

package routeguide;

// Interface exported by the server.
service RouteGuide {
  // A simple RPC.
  //
  // Obtains the feature at a given position.
  //
  // A feature with an empty name is returned if there's no feature at the given
  // position.
  rpc GetFeature(Point) returns (Feature) {}

  // A server-to-client streaming RPC.
  //
  // Obtains the Features available within the given Rectangle.  Results are
  // streamed rather than returned at once (e.g. in a response message with a
  // repeated field), as the rectangle may cover a large area and contain a
  // huge number of features.
  rpc ListFeatures(Rectangle) returns (stream Feature) {}

  // A client-to-server streaming RPC.
  //
  // Accepts a stream of Points on a route being traversed, returning a
  // RouteSummary when traversal is completed.
  rpc RecordRoute(stream Point) returns (RouteSummary) {}

  // A Bidirectional streaming RPC.
  //
  // Accepts a stream of RouteNotes sent while a route is being traversed,
  // while receiving other RouteNotes (e.g. from other users).
  rpc RouteChat(stream RouteNote) returns (stream RouteNote) {}
}

// Points are represented as latitude-longitude pairs in the E7 representation
// (degrees multiplied by 10**7 and rounded to the nearest integer).
// Latitudes should be in the range +/- 90 degrees and longitude should be in
// the range +/- 180 degrees (inclusive).
message Point {
  int32 latitude = 1;
  int32 longitude = 2;
}

// A latitude-longitude rectangle, represented as two diagonally opposite
// points "lo" and "hi".
message Rectangle {
  // One corner of the rectangle.
  Point lo = 1;

  // The other corner of the rectangle.
  Point hi = 2;
}

// A feature names something at a given point.
//
// If a feature could not be named, the name is empty.
message Feature {
  // The name of the feature.
  string name = 1;

  // The point where the feature is detected.
  Point location = 2;
}

// A RouteNote is a message sent while at a given point.
message RouteNote {
  // The location from which the message is sent.
  Point location = 1;

  // The message to be sent.
  string message = 2;
}

// A RouteSummary is received in response to a RecordRoute rpc.
//
// It contains the number of individual points received, the number of
// detected features, and the total distance covered as the cumulative sum of
// the distance between each point.
message RouteSummary {
  // The number of points received.
  int32 point_count = 1;

  // The number of known features passed while traversing the route.
  int32 feature_count = 2;

  // The distance covered in metres.
  int32 distance = 3;

  // The duration of the traversal in seconds.
  int32 elapsed_time = 4;
}
  • 需要引入Nuget包
Install-Package Google.Protobuf
Install-Package Grpc
Install-Package Grpc.Tools
  • 生成客户端和服务器代码，在Grpc.Tools 1.17版本之后 Grpc.ToolsNuGet包与MSBuild集成从.proto文件自动生成C#代码。但是在1.17以前的版本需要使用protoc.exe和grpc_csharp_plugin.exe 来生成代码，如下命令： 
protoc -I . --csharp_out . --grpc_out . --plugin=protoc-gen-grpc=grpc_csharp_plugin.exe Helloworld.proto

 　　在Grpc.Tools 1.17版本之后只需要使用donet build RouteGuid.sln或者直接在Visual Studio构建项目来完成，构建重新生成目录下的以下文件RouteGuide/obj/Debug/TARGET_FRAMEWORK：RouteGuide.cs和RouteGuideGrpc.cs
