golang http example

To provide an HTTP example using the Go programming language (Golang), we can use the built-in "net/http" package. Here is a step-by-step explanation of the example:

Step 1: Import the required packages import ( "fmt" "net/http" )

Step 2: Define a handler function to process the HTTP requests func handler(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello, World!") // Sends "Hello, World!" as the response body }

Step 3: Register the handler function with the default HTTP server http.HandleFunc("/", handler)

Step 4: Start the HTTP server http.ListenAndServe(":8080", nil)

Explanation: - In step 1, we import the necessary packages, "fmt" for formatting and printing, and "net/http" for HTTP functionality. - In step 2, we define a handler function that takes in an http.ResponseWriter and an http.Request as parameters. The handler function writes the response "Hello, World!" to the http.ResponseWriter. - In step 3, we register the handler function with the default HTTP server using http.HandleFunc(). This tells the server to use the handler function when a request is made to the root ("/") URL. - In step 4, we start the HTTP server on port 8080 using http.ListenAndServe(). The server listens for incoming requests and handles them using the registered handler function.

That's it! This example sets up a basic HTTP server in Go that responds with "Hello, World!" to any incoming request.
