Go is a powerful and flexible language for building web applications.
Thenetpackage plays an essential role in Go’s ecosystem.
Like most server-side programming languages, Go ships with an HTTP package for interacting with the HTTP protocol.
The relevant Go package is thehttppackage, a sub-package of thenetpackage.
What Is the net/http Package?
Thenet/httppackage is one of the standard libraries in Go.
Here’s a program torun a simple server in Go:
Thehandlerfunction is a typical request-response handler for thehttppackage.
This function writes the string “Hello, World!”
to the HTTP response writer.
string displayed in your net internet ride.
Handling Requests and Responses
you might handle incoming requests with theHandleFuncmethod of thehttppackage.
TheHandleFuncmethod takes in a route string and a handler function.
The code above uses thehttppackage to define an HTTP handler function for the/usersroute.
The handler function takes theResponseWriterandRequestmethods as arguments.
If the method isGET, the handler will handle theGETrequest.
Otherwise, the method isPOST;it will handle thePOSTrequest.
you’ve got the option to use theWriteHeadermethod of yourResponseWriterinstance to write headers to the client.
The returned HTTP handler is an anonymous function that takes in an HTTP response writer and an HTTP request.
you’re free to handle middleware functions with theHandlemethod of thehttppackage.
TheHandlemethod takes in the route and the middleware function.
it’s possible for you to redirect to another webpage using theRedirectmethod of thehttppackage.
TheRedirectmethod takes in theResponseWriterandRequestinstances, the new page URL, and a status code for the redirect.
