tcp-server

Introduction

This is a simple tcp server written in golang. It does the following at the moment:

Exposes tcp servers at 2 ports: a. 9090: Any valid json message on this port, stores the passed message into a in-memory buffer until 20 seconds after which, asynchrously, a go-routine pulls out the data from the buffered storage and writes it to a file. b. 8080: Any request on this port, prints all the data from the file + the in-memory buffered storage

Run code:

1. Build and run the source using make run
2. On the other side a json payload can be sent to the running tcp server as:
   • Using ncat on linux as :
     • ncat 127.0.0.1 9090 < $path_to_json_file or
     • ncat 127.0.0.1 9090 and then type a valid json string on the cursor prompt
   • Using the test code in test package as:
     • go build test/main.go
     • cd test;./main
3. To see data buffered in-memory + data in file:
   • ncat 127.0.0.1 8080 < $path_to_file_with_any_string or ncat 127.0.0.1 8080 and then type any string on the cursor prompt
   • Or modify the test script described above in 3.ii as per needs
