How to use Go language to write the user personal information editing module in the door-to-door cooking system?

With the development of the Internet, many traditional services have begun to transform online. Among them, door-to-door cooking services are becoming more and more popular. In such services, the management of users' personal information is particularly important. This article will introduce how to use Go language to write the user personal information editing module in the door-to-door cooking system, and provide specific code examples.

1. Set up a development environment
First, we need to set up a development environment for the Go language. You can download the installation package corresponding to the operating system from the Go official website (https://golang.org/) and install it according to the prompts.

2. Create the project structure
After the development environment is set up, we can start creating the project. Execute the following command in the command line to create the folder structure of the project:

$ mkdir user-info-edit
$ cd user-info-edit
$ mkdir controllers models router utils
$ touch main.go

3. Write model code
Create a file named user.go in the models folder to define user information model. Edit and fill in the following code:

package models

type User struct {
    ID       uint   `json:"id,omitempty"`
    Name     string `json:"name,omitempty"`
    Age      int    `json:"age,omitempty"`
    Address  string `json:"address,omitempty"`
    Email    string `json:"email,omitempty"`
    Password string `json:"password,omitempty"`
}

4. Write the controller code
Create a file named user_controller.go in the controllers folder to implement the operation controller of user information. Edit and fill in the following code:

package controllers

import (
    "encoding/json"
    "fmt"
    "net/http"

    "user-info-edit/models"
    "user-info-edit/utils"
)

func UpdateUserInfo(w http.ResponseWriter, r *http.Request) {
    user := models.User{}

    err := json.NewDecoder(r.Body).Decode(&user)
    if err != nil {
        utils.RespondWithError(w, http.StatusBadRequest, "Invalid request payload")
        return
    }

    // 在这里实现具体的用户信息编辑逻辑，比如更新数据库记录等

    utils.RespondWithJSON(w, http.StatusOK, user)
}

5. Write routing code
Create a file named router.go in the router folder to implement the routing function. Edit and fill in the following code:

package router

import (
    "net/http"

    "user-info-edit/controllers"
)

func Init() {
    http.HandleFunc("/api/edit", controllers.UpdateUserInfo)
}

6. Write auxiliary function code
Create a file named utils.go in the utils folder to define some auxiliary functions. Edit and fill in the following code:

package utils

import "net/http"

func RespondWithError(w http.ResponseWriter, code int, message string) {
    RespondWithJSON(w, code, map[string]string{"error": message})
}

func RespondWithJSON(w http.ResponseWriter, code int, payload interface{}) {
    response, _ := json.Marshal(payload)

    w.Header().Set("Content-Type", "application/json")
    w.WriteHeader(code)
    w.Write(response)
}

7. Write the main function code
Edit and fill in the content of the main.go file as follows:

package main

import (
    "log"
    "net/http"

    "user-info-edit/router"
)

func main() {
    router.Init()

    log.Fatal(http.ListenAndServe(":8080", nil))
}

8. Start the service
On the command line Execute the following command to start the service:

$ go run main.go

After the service is successfully started, you can edit the user's personal information by accessing http://localhost:8080/api/edit.

Summary:
Through the above steps, we have successfully written the user personal information editing module in the door-to-door cooking system using Go language, and provided specific code examples. Developers can make appropriate extensions and modifications based on specific needs to meet actual business needs. At the same time, this example also demonstrates the simplicity and efficiency of Go language in web development.
