Go API Server with GET/POST

This is a simple Go API server that supports both GET and POST requests. The server allows the user to specify the port number via a command-line argument.

Features

• GET /: Returns a welcome message.
• POST /post: Accepts JSON data and returns the same data in the response.

Requirements

• Go 1.16 or later.

How to Run

1. Clone the repository

git clone https://github.com/sojoudian/go-api-server.git
cd go-api-server

2. Run the server

You can specify the port number when starting the server. If no port number is provided, it defaults to 8091.

go run main.go -port=8080

This will start the server on localhost:8080.

If you want to use the default port (8091), simply run:

go run main.go

3. Test the Endpoints

GET Request

You can test the GET request by opening the following URL in your browser or using curl:

curl http://localhost:8080/

You should see the following response:

Welcome to the Go API

POST Request

To test the POST endpoint, you can use curl to send a JSON payload:

curl -X POST -d '{"name": "John", "content": "Hello World!"}' http://localhost:8080/post -H "Content-Type: application/json"

The response should return the same JSON you sent:

{
    "name": "John",
    "content": "Hello World!"
}

Customization

To change the port, use the -port flag when running the server. For example, to run on port 3000:

go run main.go -port=3000
