What efficient functions can be achieved by Golang microservice development?
With the rise of cloud computing and distributed architecture, microservice architecture has become a very popular architectural style. As Golang is an efficient, concise and highly concurrency programming language, more and more developers are beginning to choose Golang in microservice development. The following will introduce some efficient functions commonly used in Golang microservice development and give specific code examples.
package main import ( "fmt" "time" ) func main() { for i := 0; i < 10; i++ { go func(num int) { time.Sleep(time.Second) fmt.Println("goroutine", num) }(i) } time.Sleep(2 * time.Second) }
package main import ( "log" "net" "net/http" "net/rpc" ) type Args struct { A, B int } type MathService struct{} func (m *MathService) Add(args *Args, reply *int) error { *reply = args.A + args.B return nil } func main() { math := new(MathService) rpc.Register(math) rpc.HandleHTTP() l, err := net.Listen("tcp", ":1234") if err != nil { log.Fatal("listen error:", err) } log.Fatal(http.Serve(l, nil)) }
package main import ( "encoding/json" "fmt" ) type Person struct { Name string `json:"name"` Age int `json:"age"` } func main() { p := Person{ Name: "John", Age: 30, } data, err := json.Marshal(p) if err != nil { fmt.Println("json marshal error:", err) return } fmt.Println(string(data)) var p2 Person err = json.Unmarshal(data, &p2) if err != nil { fmt.Println("json unmarshal error:", err) return } fmt.Println(p2) }
package main import ( "fmt" "net/http" ) func handler(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello, World!") } func main() { http.HandleFunc("/", handler) http.ListenAndServe(":8080", nil) }
In summary, Golang microservice development has concurrent processing , lightweight inter-service communication, efficient serialization and deserialization, and excellent performance and other efficient functions. These features make it easier for developers to build high-performance, scalable microservice systems.
