What business functions can Golang microservice development support?

Golang microservice development can support a variety of different business functions. It is a simple and efficient programming language with fast compilation and high concurrency processing capabilities, which is very suitable for building microservice architecture.

1. User Management
   Microservices can support user management functions, including user registration, login, identity verification, etc. The following is an example of a user management microservice developed using Golang:

// main.go
package main

import (
    "fmt"
    "net/http"
    "github.com/gorilla/mux"
)

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/user/register", RegisterUser).Methods("POST")
    router.HandleFunc("/user/login", LoginUser).Methods("POST")

    fmt.Println("Server started on port 8080")
    http.ListenAndServe(":8080", router)
}

func RegisterUser(w http.ResponseWriter, r *http.Request) {
    // 用户注册逻辑
}

func LoginUser(w http.ResponseWriter, r *http.Request) {
    // 用户登录逻辑
}

2. Product Management
   The microservice can also support product management functions, including product list display, product details query, product Add etc. The following is an example of a product management microservice developed using Golang:

// main.go
package main

import (
    "fmt"
    "net/http"
    "github.com/gorilla/mux"
)

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/product/list", GetProductList).Methods("GET")
    router.HandleFunc("/product/{id}", GetProductDetail).Methods("GET")
    router.HandleFunc("/product/add", AddProduct).Methods("POST")

    fmt.Println("Server started on port 8080")
    http.ListenAndServe(":8080", router)
}

func GetProductList(w http.ResponseWriter, r *http.Request) {
    // 获取商品列表逻辑
}

func GetProductDetail(w http.ResponseWriter, r *http.Request) {
    // 获取商品详情逻辑
}

func AddProduct(w http.ResponseWriter, r *http.Request) {
    // 添加商品逻辑
}

3. Order Management
   Microservices can also support order management functions, including order placement, payment, order query, etc. The following is an example of an order management microservice developed using Golang:

// main.go
package main

import (
    "fmt"
    "net/http"
    "github.com/gorilla/mux"
)

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/order/create", CreateOrder).Methods("POST")
    router.HandleFunc("/order/pay/{id}", PayOrder).Methods("POST")
    router.HandleFunc("/order/{id}", GetOrderDetail).Methods("GET")

    fmt.Println("Server started on port 8080")
    http.ListenAndServe(":8080", router)
}

func CreateOrder(w http.ResponseWriter, r *http.Request) {
    // 创建订单逻辑
}

func PayOrder(w http.ResponseWriter, r *http.Request) {
    // 支付订单逻辑
}

func GetOrderDetail(w http.ResponseWriter, r *http.Request) {
    // 获取订单详情逻辑
}

The above are several examples that show how to use Golang to develop microservices to support different business functions. Of course, actual development may involve more complex business logic and database operations, but Golang's high concurrency performance and concise syntax make it an ideal choice for building microservices. Using Golang for microservice development can help you speed up development and provide good scalability and maintainability.
