# gRPC C++ Message Compression Tutorial
### Prerequisite
Make sure you have run the [hello world example](../helloworld) or understood the basics of gRPC. We will not dive into the details that have been discussed in the hello world example.
### Get the tutorial source code
The example code for this and our other examples lives in the `examples` directory. Clone this repository to your local machine by running the following command:
```sh
$ git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc
```
Change your current directory to examples/cpp/compression
```sh
$ cd examples/cpp/compression/
```
### Generating gRPC code
To generate the client and server side interfaces:
```sh
$ make helloworld.grpc.pb.cc helloworld.pb.cc
```
Which internally invokes the proto-compiler as:
```sh
$ protoc -I ../../protos/ --grpc_out=. --plugin=protoc-gen-grpc=grpc_cpp_plugin ../../protos/helloworld.proto
$ protoc -I ../../protos/ --cpp_out=. ../../protos/helloworld.proto
```
### Writing a client and a server
The client and the server can be based on the hello world example.
Additionally, we can configure the compression settings.
In the client, set the default compression algorithm of the channel via the channel arg.
```cpp
ChannelArguments args;
// Set the default compression algorithm for the channel.
args.SetCompressionAlgorithm(GRPC_COMPRESS_GZIP);
GreeterClient greeter(grpc::CreateCustomChannel(
"localhost:50051", grpc::InsecureChannelCredentials(), args));
```
Each call's compression configuration can be overwritten by client context.
```cpp
// Overwrite the call's compression algorithm to DEFLATE.
context.set_compression_algorithm(GRPC_COMPRESS_DEFLATE);
```
In the server, set the default compression algorithm via the server builder.
```cpp
ServerBuilder builder;
// Set the default compression algorithm for the server.
builder.SetDefaultCompressionAlgorithm(GRPC_COMPRESS_GZIP);
```
Each call's compression configuration can be overwritten by server context.
```cpp
// Overwrite the call's compression algorithm to DEFLATE.
context->set_compression_algorithm(GRPC_COMPRESS_DEFLATE);
```
For a working example, refer to [greeter_client.cc](greeter_client.cc) and [greeter_server.cc](greeter_server.cc).
Build and run the (compressing) client and the server by the following commands.
```sh
make
./greeter_server
```
```sh
./greeter_client
```

# Metadata Example
## Overview
This example shows you how to add custom headers on the client and server and
how to access them.
Custom metadata must follow the "Custom-Metadata" format listed in
https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md, with the
exception of binary headers, which don't have to be base64 encoded.
### Get the tutorial source code
The example code for this and our other examples lives in the `examples` directory. Clone this repository to your local machine by running the following command:
```sh
$ git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc
```
Change your current directory to examples/cpp/metadata
```sh
$ cd examples/cpp/metadata
```
### Generating gRPC code
To generate the client and server side interfaces:
```sh
$ make helloworld.grpc.pb.cc helloworld.pb.cc
```
Which internally invokes the proto-compiler as:
```sh
$ protoc -I ../../protos/ --grpc_out=. --plugin=protoc-gen-grpc=grpc_cpp_plugin ../../protos/helloworld.proto
$ protoc -I ../../protos/ --cpp_out=. ../../protos/helloworld.proto
```
### Try it!
Build client and server:
```sh
$ make
```
Run the server, which will listen on port 50051:
```sh
$ ./greeter_server
```
Run the client (in a different terminal):
```sh
$ ./greeter_client
```
If things go smoothly, you will see in the client terminal:
"Client received initial metadata from server: initial metadata value"
"Client received trailing metadata from server: trailing metadata value"
"Client received message: Hello World"
And in the server terminal:
"Header key: custom-bin , value: 01234567"
"Header key: custom-header , value: Custom Value"
"Header key: user-agent , value: grpc-c++/1.16.0-dev grpc-c/6.0.0-dev (linux; chttp2; gao)"
We did not add the user-agent metadata as a custom header. This shows how
the gRPC framework adds some headers under the hood that may show up in the
metadata map.

BACKGROUND
-------------
For this sample, we've already generated the server and client stubs from [helloworld.proto][].
Example projects in this directory depend on the [Grpc](https://www.nuget.org/packages/Grpc/)
and [Google.Protobuf](https://www.nuget.org/packages/Google.Protobuf/) NuGet packages
which have been already added to the project for you.
This is a version of the helloworld example using the dotnet SDK
tools to compile [helloworld.proto][] in a common library, build the server
and the client, and run them.
PREREQUISITES
-------------
- The [.NET Core SDK 2.1+](https://www.microsoft.com/net/core)
You can also build the example directly using Visual Studio 2017, but it's not a requirement.
BUILD
-------
From the `examples/csharp/Helloworld` directory:
You can also build the solution `Greeter.sln` using Visual Studio 2017,
but it's not a requirement.
- `dotnet build Greeter.sln`
Try it!
-------
BUILD AND RUN
-------------
- Run the server
- Build and run the server
```
> cd GreeterServer
> dotnet run -f netcoreapp2.1
> dotnet run -p GreeterServer
```
- Run the client
- Build and run the client
```
> cd GreeterClient
> dotnet run -f netcoreapp2.1
> dotnet run -p GreeterClient
```

BACKGROUND
-------------
This is a different version of the helloworld example, using the old-style .csproj
files supported by VS2013 and VS2015 (and older versions of mono).
You can still use gRPC with the old-style .csproj files, but [using the new-style
.csproj projects](../helloworld/README.md) (supported by VS2017 and dotnet SDK) is recommended.
For this sample, we've already generated the server and client stubs from [helloworld.proto][].
Example projects depend on the [Grpc](https://www.nuget.org/packages/Grpc/), [Grpc.Tools](https://www.nuget.org/packages/Grpc.Tools/)
This is a different version of the helloworld example, using the "classic" .csproj

You can still use gRPC with the classic .csproj files, but [using the new-style

and [Google.Protobuf](https://www.nuget.org/packages/Google.Protobuf/) NuGet packages
which have been already added to the project for you.

An example showing how to add custom HTTP2 headers (or [metadata](https://grpc.io/grpc/python/glossary.html) in gRPC glossary)
HTTP2 supports initial headers and trailing headers, which gRPC utilizes both of them ([learn more](https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md)).
More complete documentation lives at [grpc.io](https://grpc.io/docs/tutorials/basic/python.html).
