Handling request methods in Golang's net/http
library isn't as intuitive as you'd expect.
In the request, library there's a Method
field that allows you to see what method a request uses.
func hello(w http.ResponseWriter, req *http.Request) {
fmt.Fprintln(w, "Hello, world")
}
Starting with the example above, if you want the method to only respond to GET
requests, add a conditional statement to make the request respond to only GET
requests, and reject non-GET
requests.
Take a look at an example of how the code will look after doing this:
func hello(w http.ResponseWriter, req *http.Request) {
if req.Method == "GET" {
fmt.Fprintln(w, "Hello, world")
} else {
w.WriteHeader(http.StatusMethodNotAllowed)
fmt.Fprintf(w, "Cannot %s %s", req.Method, req.URL)
}
}
You can apply this technique to any other type of request method, and you'll achieve the result you want.
