Error Handling Example

Overview

This example shows you how to return error from the server and how to handle it on the client.

Try it!

Once you have working gRPC, you can build this example using either bazel or cmake.

Run the server, which will listen on port 50051:

$ ./greeter_server

Run the client (in a different terminal):

$ ./greeter_client

If things go smoothly, you will see the client output:

### Send: SayHello(name=)
Failed. Code=3 Message=Length of `Name` should be between 1 and 10
### Send: SayHello(name=ItsTooLongName)
Failed. Code=3 Message=Length of `Name` should be between 1 and 10
### Send: SayHello(name=World)
Ok. ReplyMessage=Hello World
