| # 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: |
| |
| ```sh |
| $ ./greeter_server |
| ``` |
| |
| Run the client (in a different terminal): |
| |
| ```sh |
| $ ./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 |
| ``` |
