By walking through this example you'll learn how to: + +- Define a service in a .proto file. +- Generate server and client code using the protocol buffer compiler. +- Use the C# gRPC API to write a simple client and server for your service. + +It assumes that you have read the [Getting started](https://github.com/grpc/grpc-common) guide and are familiar with [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). Note that the example in this tutorial only uses the proto2 version of the protocol buffers language, as proto3 support for C# is not ready yet (see [protobuf C# README](https://github.com/google/protobuf/tree/master/csharp#proto2--proto3)). + +This isn't a comprehensive guide to using gRPC in C#: more reference documentation is coming soon. + +## Why use gRPC? + +Our example is a simple route mapping application that lets clients get information about features on their route, create a summary of their route, and exchange route information such as traffic updates with the server and other clients. + +With gRPC we can define our service once in a .proto file and implement clients and servers in any of gRPC's supported languages, which in turn can be run in environments ranging from servers inside Google to your own tablet - all the complexity of communication between different languages and environments is handled for you by gRPC. We also get all the advantages of working with protocol buffers, including efficient serialization, a simple IDL, and easy interface updating. + +## Example code and setup + +The example code for our tutorial is in [grpc/grpc-common/csharp/route_guide](https://github.com/grpc/grpc-common/tree/master/csharp/route_guide). To download the example, clone the `grpc-common` repository by running the following command: +```shell +$ git clone https://github.com/google/grpc-common.git +``` + +All the files for this tutorial are in the directory `grpc-common/csharp/route_guide`. +Open the solution `grpc-common/csharp/route_guide/RouteGuide.sln` from Visual Studio (or Monodevelop on Linux). + +You also should have the relevant tools installed to generate the server and client interface code. + +**TODO: more on how to install protoc** + +## Defining the service + +Our first step (as you'll know from [Getting started](https://github.com/grpc/grpc-common)) is to define the gRPC *service* and the method *request* and *response* types using [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). You can see the complete .proto file in [`grpc-common/csharp/route_guide/RouteGuide/protos/route_guide.proto`](https://github.com/grpc/grpc-common/blob/master/sharp/route_guide/RouteGuide/protos/route_guide.proto). + +To define a service, you specify a named `service` in your .proto file: + +```protobuf +service RouteGuide { + ... +} +``` + +Then you define `rpc` methods inside your service definition, specifying their request and response types. gRPC lets you define four kinds of service method, all of which are used in the `RouteGuide` service: + +- A *simple RPC* where the client sends a request to the server using the stub and waits for a response to come back, just like a normal function call. +```protobuf + // Obtains the feature at a given position. + rpc GetFeature(Point) returns (Feature) {} +``` + +- A *server-side streaming RPC* where the client sends a request to the server and gets a stream to read a sequence of messages back. The client reads from the returned stream until there are no more messages. As you can see in our example, you specify a server-side streaming method by placing the `stream` keyword before the *response* type. +```protobuf + // 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-side streaming RPC* where the client writes a sequence of messages and sends them to the server, again using a provided stream. Once the client has finished writing the messages, it waits for the server to read them all and return its response. You specify a server-side streaming method by placing the `stream` keyword before the *request* type. +```protobuf + // 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* where both sides send a sequence of messages using a read-write stream. The two streams operate independently, so clients and servers can read and write in whatever order they like: for example, the server could wait to receive all the client messages before writing its responses, or it could alternately read a message then write a message, or some other combination of reads and writes. The order of messages in each stream is preserved. You specify this type of method by placing the `stream` keyword before both the request and the response. +```protobuf + // 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) {} +``` + +Our .proto file also contains protocol buffer message type definitions for all the request and response types used in our service methods - for example, here's the `Point` message type: +```protobuf +// 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; +} +``` + + +## Generating client and server code + +Next we need to generate the gRPC client and server interfaces from our .proto service definition. We do this using the protocol buffer compiler `protoc` with a special gRPC C# plugin. + +If you want to run this yourself, make sure you've installed protoc and followed the gRPC C# plugin [installation instructions](https://github.com/grpc/grpc/blob/master/INSTALL) first. + +**TODO: more on how to install protoc and grpc_csharp_plugin** + +Once that's done, the following command can be used to generate the C# code. + +```shell +$ protoc -I RouteGuide/protos --csharp_out=RouteGuide --grpc_out=RouteGuide --plugin=protoc-gen-grpc=`which grpc_csharp_plugin` RouteGuide/protos/route_guide.proto +``` + +**TODO: command for windows** + +Running this command regenerates the following files in the RouteGuide directory: +- `RouteGuide/RouteGuide.cs` defines a namespace `examples` + - This contains all the protocol buffer code to populate, serialize, and retrieve our request and response message types +- `RouteGuide/RouteGuideGrpc.cs`, provides stub and service classes + - an interface `RouteGuide.IRouteGuide` to inherit from when defining RouteGuide service implementations + - a class `RouteGuide.RouteGuideClient` that can be used to access remote RouteGuide instances + + + +## Creating the server + +First let's look at how we create a `RouteGuide` server. If you're only interested in creating gRPC clients, you can skip this section and go straight to [Creating the client](#client) (though you might find it interesting anyway!). + +There are two parts to making our `RouteGuide` service do its job: +- Implementing the service interface generated from our service definition: doing the actual "work" of our service. +- Running a gRPC server to listen for requests from clients and return the service responses. + +You can find our example `RouteGuide` server in [grpc-common/csharp/route_guide/RouteGuideServer/RouteGuideImpl.cs](https://github.com/grpc/grpc-common/blob/master/csharp/route_guide/RouteGuideServer/RouteGuideServerImpl.cs). Let's take a closer look at how it works. + +### Implementing RouteGuide + +As you can see, our server has a `RouteGuideImpl` class that implements the generated `RouteGuide.IRouteGuide`: + +```csharp +// RouteGuideImpl provides an implementation of the RouteGuide service. +public class RouteGuideImpl : RouteGuide.IRouteGuide +``` + +`RouteGuideImpl` implements all our service methods. Let's look at the simplest type first, `GetFeature`, which just gets a `Point` from the client and returns the corresponding feature information from its database in a `Feature`. + +```csharp + public Task GetFeature(Grpc.Core.ServerCallContext context, Point request) + { + return Task.FromResult(CheckFeature(request)); + } +``` + +The method is passed a context for the RPC (which is empty in the alpha release), the client's `Point` protocol buffer request, and returns a `Feature` protocol buffer. In the method we create the `Feature` with the appropriate information, and then return it. To allow asynchronous +implementation, the method returns `Task` rather than just `Feature`. You are free to perform your computations synchronously and return +the result once you've finished, just as we do in the example. + +Now let's look at something a bit more complicated - a streaming RPC. `ListFeatures` is a server-side streaming RPC, so we need to send back multiple `Feature` protocol buffers to our client. + +```csharp + // in RouteGuideImpl + public async Task ListFeatures(Grpc.Core.ServerCallContext context, Rectangle request, + Grpc.Core.IServerStreamWriter responseStream) + { + int left = Math.Min(request.Lo.Longitude, request.Hi.Longitude); + int right = Math.Max(request.Lo.Longitude, request.Hi.Longitude); + int top = Math.Max(request.Lo.Latitude, request.Hi.Latitude); + int bottom = Math.Min(request.Lo.Latitude, request.Hi.Latitude); + + foreach (var feature in features) + { + if (!RouteGuideUtil.Exists(feature)) + { + continue; + } + + int lat = feature.Location.Latitude; + int lon = feature.Location.Longitude; + if (lon >= left && lon <= right && lat >= bottom && lat <= top) + { + await responseStream.WriteAsync(feature); + } + } + } +``` + +As you can see, here the request object is a `Rectangle` in which our client wants to find `Feature`s, but instead of returning a simple response we need to write responses to an asynchronous stream `IServerStreamWriter` using async method `WriteAsync`. + +Similarly, the client-side streaming method `RecordRoute` uses an [IAsyncEnumerator](https://github.com/Reactive-Extensions/Rx.NET/blob/master/Ix.NET/Source/System.Interactive.Async/IAsyncEnumerator.cs), to read the stream of requests using async method `MoveNext` and property `Current`. + +```csharp + public async Task RecordRoute(Grpc.Core.ServerCallContext context, + Grpc.Core.IAsyncStreamReader requestStream) + { + int pointCount = 0; + int featureCount = 0; + int distance = 0; + Point previous = null; + var stopwatch = new Stopwatch(); + stopwatch.Start(); + + while (await requestStream.MoveNext()) + { + var point = requestStream.Current; + pointCount++; + if (RouteGuideUtil.Exists(CheckFeature(point))) + { + featureCount++; + } + if (previous != null) + { + distance += (int) CalcDistance(previous, point); + } + previous = point; + } + + stopwatch.Stop(); + return RouteSummary.CreateBuilder().SetPointCount(pointCount) + .SetFeatureCount(featureCount).SetDistance(distance) + .SetElapsedTime((int) (stopwatch.ElapsedMilliseconds / 1000)).Build(); + } +``` +Finally, let's look at our bidirectional streaming RPC `RouteChat`. + +```csharp + public async Task RouteChat(Grpc.Core.ServerCallContext context, + Grpc.Core.IAsyncStreamReader requestStream, Grpc.Core.IServerStreamWriter responseStream) + { + while (await requestStream.MoveNext()) + { + var note = requestStream.Current; + List notes = GetOrCreateNotes(note.Location); + + List prevNotes; + lock (notes) + { + prevNotes = new List(notes); + } + + foreach (var prevNote in prevNotes) + { + await responseStream.WriteAsync(prevNote); + } + + lock (notes) + { + notes.Add(note); + } + } + } +``` + +Here the method receives both `requestStream` and `responseStream` as an argument. Reading the requests is done in a same way as in the `RecordRoute` example. Writing the responses is done the same way as in the `ListFeatures` example. + +### Starting the server + +Once we've implemented all our methods, we also need to start up a gRPC server so that clients can actually use our service. The following snippet shows how we do this for our `RouteGuide` service: + +```csharp +var features = RouteGuideUtil.ParseFeatures(RouteGuideUtil.DefaultFeaturesFile); +GrpcEnvironment.Initialize(); + +Server server = new Server(); +server.AddServiceDefinition(RouteGuide.BindService(new RouteGuideImpl(features))); +int port = server.AddListeningPort("localhost", 50052); +server.Start(); + +Console.WriteLine("RouteGuide server listening on port " + port); +Console.WriteLine("Press any key to stop the server..."); +Console.ReadKey(); + +server.ShutdownAsync().Wait(); +GrpcEnvironment.Shutdown(); +``` +As you can see, we build and start our server using `Grpc.Core.Server` class. To do this, we: + +1. Create an instance of `Grpc.Core.Server`. +1. Create an instance of our service implementation class `RouteGuideImpl`. +3. Register our service implementation with the server using method `AddServiceDefinition` and the generated method `RouteGuide.BindService`. +2. Specify the address and port we want to use to listen for client requests using the `AddListeningPort` method. +4. Call `Start` on the server instance to start an RPC server for our service. + + +## Creating the client + +In this section, we'll look at creating a C# client for our `RouteGuide` service. You can see our complete example client code in [grpc-common/csharp/route_guide/RouteGuideClient/Program.cs](https://github.com/grpc/grpc-common/blob/master/csharp/route_guide/RouteGuideClient/Program.cs). + +### Creating a stub + +To call service methods, we first need to create a *stub*. + +First, we need to create a gRPC client channel that will connect to gRPC server. Then, we use the `RouteGuide.NewStub` method of the `RouteGuide` class generated from our .proto. + +```csharp +GrpcEnvironment.Initialize(); + +using (Channel channel = new Channel("127.0.0.1:50052")) +{ + var client = RouteGuide.NewStub(channel); + + // YOUR CODE GOES HERE +} + +GrpcEnvironment.Shutdown(); +``` + +### Calling service methods + +Now let's look at how we call our service methods. gRPC C# provides asynchronous versions of each of the supported method types. For convenience, +gRPC C# also provides a synchronous method stub, but only for simple (single request/single response) RPCs. + +#### Simple RPC + +Calling the simple RPC `GetFeature` in a synchronous way is nearly as straightforward as calling a local method. + +```csharp +Point request = Point.CreateBuilder().SetLatitude(409146138).SetLongitude(-746188906).Build(); +Feature feature = client.GetFeature(request); +``` + +As you can see, we create and populate a request protocol buffer object (in our case `Point`), and call the desired method on the client object, passing it the request. If the RPC finishes with success, the response protocol buffer (in our case `Feature`) will be returned. Otherwise, an exception of type `RpcException` will be thrown, indicating the status code of the problem. + +Alternatively, if you are in async context, you can call an asynchronous version of the method (and use `await` keyword to await the result): +```csharp +Point request = Point.CreateBuilder().SetLatitude(409146138).SetLongitude(-746188906).Build(); +Feature feature = await client.GetFeatureAsync(request); +``` + +#### Streaming RPCs + +Now let's look at our streaming methods. If you've already read [Creating the server](#server) some of this may look very familiar - streaming RPCs are implemented in a similar way on both sides. The difference with respect to simple call is that the client methods return an instance of a call object, that provides access to request/response streams and/or asynchronous result (depending on the streaming type you are using). + +Here's where we call the server-side streaming method `ListFeatures`, which has property `ReponseStream` of type `IAsyncEnumerator` + +```csharp +using (var call = client.ListFeatures(request)) +{ + while (await call.ResponseStream.MoveNext()) + { + Feature feature = call.ResponseStream.Current; + Console.WriteLine("Received " + feature.ToString()); + } +} +``` + +The client-side streaming method `RecordRoute` is similar, except we use the property `RequestStream` to write the requests one by one using `WriteAsync` and eventually signal that no more request will be send using `CompleteAsync`. The method result can be obtained through the property +`Result`. +```csharp +using (var call = client.RecordRoute()) +{ + foreach (var point in points) + { + await call.RequestStream.WriteAsync(point); + } + await call.RequestStream.CompleteAsync(); + + RouteSummary summary = await call.Result; +} +``` + +Finally, let's look at our bidirectional streaming RPC `RouteChat`. In this case, we write the request to `RequestStream` and receive the responses from `ResponseStream`. As you can see from the example, the streams are independent of each other. + +```csharp + using (var call = client.RouteChat()) + { + var responseReaderTask = Task.Run(async () => + { + while (await call.ResponseStream.MoveNext()) + { + var note = call.ResponseStream.Current; + Console.WriteLine("Received " + note); + } + }); + + foreach (RouteNote request in requests) + { + await call.RequestStream.WriteAsync(request); + } + await call.RequestStream.CompleteAsync(); + await responseReaderTask; +} +``` + +## Try it out! + +Build client and server: + +Open the solution `grpc-common/csharp/route_guide/RouteGuide.sln` from Visual Studio (or Monodevelop on Linux) and hit "Build". + +Run the server, which will listen on port 50052: +``` +> cd RouteGuideServer/bin/Debug +> RouteGuideServer.exe +``` + +Run the client (in a different terminal): +``` +> cd RouteGuideClient/bin/Debug +> RouteGuideClient.exe +``` + +You can also run the server and client directly from Visual Studio. + +On Linux or Mac, use `mono RouteGuideServer.exe` and `mono RouteGuideClient.exe` to run the server and client. \ No newline at end of file diff --git a/csharp/route_guide/RouteGuide.sln b/csharp/route_guide/RouteGuide.sln new file mode 100644 index 00000000000..00065b0ba9d --- /dev/null +++ b/csharp/route_guide/RouteGuide.sln @@ -0,0 +1,34 @@ + +Microsoft Visual Studio Solution File, Format Version 12.00 +# Visual Studio 2013 +VisualStudioVersion = 12.0.31101.0 +MinimumVisualStudioVersion = 10.0.40219.1 +Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "RouteGuide", "RouteGuide\RouteGuide.csproj", "{49954D9C-5F17-4662-96B2-73BE833DD81A}" +EndProject +Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "RouteGuideClient", "RouteGuideClient\RouteGuideClient.csproj", "{D47BE663-4DE3-4206-B7A8-EA3FA066DADC}" +EndProject +Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "RouteGuideServer", "RouteGuideServer\RouteGuideServer.csproj", "{4B7C7794-BE24-4477-ACE7-18259EB73D27}" +EndProject +Global + GlobalSection(SolutionConfigurationPlatforms) = preSolution + Debug|Any CPU = Debug|Any CPU + Release|Any CPU = Release|Any CPU + EndGlobalSection + GlobalSection(ProjectConfigurationPlatforms) = postSolution + {49954D9C-5F17-4662-96B2-73BE833DD81A}.Debug|Any CPU.ActiveCfg = Debug|Any CPU + {49954D9C-5F17-4662-96B2-73BE833DD81A}.Debug|Any CPU.Build.0 = Debug|Any CPU + {49954D9C-5F17-4662-96B2-73BE833DD81A}.Release|Any CPU.ActiveCfg = Release|Any CPU + {49954D9C-5F17-4662-96B2-73BE833DD81A}.Release|Any CPU.Build.0 = Release|Any CPU + {D47BE663-4DE3-4206-B7A8-EA3FA066DADC}.Debug|Any CPU.ActiveCfg = Debug|Any CPU + {D47BE663-4DE3-4206-B7A8-EA3FA066DADC}.Debug|Any CPU.Build.0 = Debug|Any CPU + {D47BE663-4DE3-4206-B7A8-EA3FA066DADC}.Release|Any CPU.ActiveCfg = Release|Any CPU + {D47BE663-4DE3-4206-B7A8-EA3FA066DADC}.Release|Any CPU.Build.0 = Release|Any CPU + {4B7C7794-BE24-4477-ACE7-18259EB73D27}.Debug|Any CPU.ActiveCfg = Debug|Any CPU + {4B7C7794-BE24-4477-ACE7-18259EB73D27}.Debug|Any CPU.Build.0 = Debug|Any CPU + {4B7C7794-BE24-4477-ACE7-18259EB73D27}.Release|Any CPU.ActiveCfg = Release|Any CPU + {4B7C7794-BE24-4477-ACE7-18259EB73D27}.Release|Any CPU.Build.0 = Release|Any CPU + EndGlobalSection + GlobalSection(SolutionProperties) = preSolution + HideSolutionNode = FALSE + EndGlobalSection +EndGlobal diff --git a/csharp/route_guide/RouteGuide/Properties/AssemblyInfo.cs b/csharp/route_guide/RouteGuide/Properties/AssemblyInfo.cs new file mode 100644 index 00000000000..9c3441e42f4 --- /dev/null +++ b/csharp/route_guide/RouteGuide/Properties/AssemblyInfo.cs @@ -0,0 +1,36 @@ +using System.Reflection; +using System.Runtime.CompilerServices; +using System.Runtime.InteropServices; + +// General Information about an assembly is controlled through the following +// set of attributes.
