.NET Unix Socket Demo
UNIX socket server capable of handling JSON-RPC requests from mutiple simultaneous clients, 100% async without Task.Run().
Tests
A normal successful request
Make a normal JSON-RPC Request:
(cat MyCompany.MyApp.Foo.json && echo && sleep 4) | socat - UNIX-CONNECT:./DemoUnixListener/bin/Debug/netcoreapp3.1/dotnet-unix-listener.sock
Get a normal result back:
{"result":45,"id":"deadbeefcafebabe"}
Client closes connection early
Make a request and don’t wait long enough for a response
(cat MyCompany.MyApp.Foo.json && echo) | socat - UNIX-CONNECT:./DemoUnixListener/bin/Debug/netcoreapp3.1/dotnet-unix-listener.sock
Expected result in log: "Got socket exception: Broken pipe""
Request with invalid JSON
Make a bad request:
echo blub | socat - UNIX-CONNECT:./DemoUnixListener/bin/Debug/netcoreapp3.1/dotnet-unix-listener.sock
Get back an error response:
{"error":{"code":400,"message":"Bad Request"},"id":"deadbeefcafebabe"}
Request with Unknown Method
Make a request with unknown method:
(cat MyCompany.MyApp.Bar.unknownmethod.json && echo && sleep 3) | socat - UNIX-CONNECT:./DemoUnixListener/bin/Debug/netcoreapp3.1/dotnet-unix-listener.sock
Get back an error:
{"error":{"code":501,"message":"Unknown method MyCompany.MyApp.Bar"},"id":"deadbeefcafebabe"}
Request with Bad Params Method
Send a request where params are missing or wrong:
(cat MyCompany.MyApp.Foo.badparams.json && echo && sleep 3) | socat - UNIX-CONNECT:./DemoUnixListener/bin/Debug/netcoreapp3.1/dotnet-unix-listener.sock
Get back an error complaining about bad params:
{"error":{"code":400,"message":"Bad params object in request"},"id":"deadbeefcafebabe"}
Request that should fail with App-defined Exception
Send request with a parameter that causes an error in the app-defined handler:
(cat MyCompany.MyApp.Foo.shouldfail.json && echo && sleep 4) | socat - UNIX-CONNECT:./DemoUnixListener/bin/Debug/netcoreapp3.1/dotnet-unix-listener.sock
Get back a custom error message
{"error":{"code":1000,"message":"We don't need no stinkin' badgers!"},"id":"deadbeefcafebabe"}
