...Create a GoLang Web Server

In this tutorial, we will go through the steps of creating a simple web server using GoLang. The web server will listen for incoming requests and return a response. To create a web server in GoLang, we will first import the net/http package. This package contains all of the functionality we need to create and handle HTTP requests. Next, we will create a function that will handle incoming requests. This function will take an http.ResponseWriter and an http.Request as arguments. The http.ResponseWriter is an interface that allows us to write the HTTP response, while the http.Request contains information about the incoming request. In the request handling function, we will write a simple response to the http.ResponseWriter. This response will be a string of text that says “Hello World!”. Finally, we will call the http.ListenAndServe() function, which will start the web server and listen for incoming requests. Here is the complete code for the GoLang web server: package main import ( "fmt" "net/http" ) func handler(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello World!") } func main() { http.HandleFunc("/", handler) err := http.ListenAndServe(":8080", nil) if err != nil { panic(err) } } Now that we have created a basic web server in GoLang, we can extend it to serve more complex content or perform more advanced tasks.
