You can use Golang to build a RESTful API that supports HTTP/2. The steps are as follows: Import the HTTP/2 module. Use the mux router to create a route definition handler function. Create an HTTP server with HTTP/2 support. Enable the HTTP/2 protocol and run the server.
Use Golang to build RESTful API and use HTTP/2
HTTP/2 is the HTTP protocol The latest version, it offers many benefits such as faster page loading, higher throughput, and lower latency for complex requests. Golang, a popular language for building RESTful APIs, provides HTTP/2 support, allowing developers to take advantage of these benefits.
The following is a simple Golang program that demonstrates how to use HTTP/2 to build a RESTful API:
package main import ( "fmt" "net/http" "github.com/gorilla/mux" ) func main() { r := mux.NewRouter() r.HandleFunc("/", homeHandler).Methods("GET") r.HandleFunc("/user/{id:[0-9]+}", userHandler).Methods("GET") srv := &http.Server{ Addr: ":8080", ReadTimeout: 10 * time.Second, WriteTimeout: 10 * time.Second, IdleTimeout: 120 * time.Second, TLSNextProto: make(map[string]func(*http.Server, *tls.Conn, http.Handler), 0), } // 启用 HTTP/2 srv.TLSNextProto["h2"] = nextProtoFuncH2 http.ListenAndServeTLS(":8080", "cert.pem", "key.pem", r) } func homeHandler(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, "Hello, HTTP/2!") } func userHandler(w http.ResponseWriter, r *http.Request) { vars := mux.Vars(r) id := vars["id"] fmt.Fprintf(w, "User with ID %s", id) }
Note: Run this program Before doing this, make sure you have installed Golang and TLS certificates.
Transfer large files:
The flow control mechanism of HTTP/2 makes it very suitable for delivering large files because it can send and receive in parallel data, thereby increasing speed.
Live streaming:
HTTP/2 supports server push, allowing live streaming applications to send data to clients quickly and efficiently.
Mobile Apps:
HTTP/2 performs very well on mobile devices and low-bandwidth connections, making it ideal for mobile applications.
Golang provides strong HTTP/2 support, allowing developers to easily build high-performance RESTful APIs. The advantages offered by HTTP/2, such as faster loading speeds and lower latency, make it ideal for a wide range of applications.
