Implementation method of customer complaint handling function in food ordering system developed with Go language

Go language development method to implement the customer complaint handling function in the ordering system

Introduction
With the popularization of the Internet and the rapid development of the catering industry, more and more More and more restaurants are beginning to adopt ordering systems to provide more convenient and efficient services. However, it is inevitable to encounter customer complaints. How to effectively handle customer complaints in the ordering system is a problem worth exploring and solving. This article will introduce the implementation method of using Go language to develop the customer complaint handling function in the ordering system, and give specific code examples.

1. Requirements Analysis
Before developing the customer complaint handling function in the ordering system, we need to analyze the requirements to determine the specific implementation method of the function. The main requirements include:

1. Customers can submit complaints through the ordering system, including the content of the complaint and related order information.
2. Complaint information needs to be recorded and saved for subsequent inquiry and statistics.
3. Store clerks need to be able to view and handle complaint information and respond to customers in a timely manner.
4. Administrators need to be able to manage and count complaint information in order to better improve services.

2. System Design
Based on the above requirements, we can design a simple complaint handling system. The system mainly includes the following modules:

1. Customer complaint module: Customers submit complaints through the ordering system interface, including complaint content and order information.
2. Complaint Recording Module: A module used to record and save complaint information.
3. Store clerk processing module: Store clerks can view and handle complaint information and respond to customers in a timely manner.
4. Administrator management module: Administrators can manage and collect statistics on complaint information in order to improve services.

3. Code Implementation
Next, we use Go language to implement each module of the above system. Before implementation, the Go language development environment needs to be installed in advance.

1. Customer Complaint Module

   // 定义投诉结构体
   type Complaint struct {
    Content string // 投诉内容
    OrderID string // 关联的订单ID
   }
   
   // 提交投诉
   func submitComplaint(content string, orderID string) {
    complaint := Complaint{
        Content: content,
        OrderID: orderID,
    }
    // 调用接口将投诉信息保存到数据库
    // ...
   }

2. Complaint Recording Module

   import (
    "database/sql"
    _ "github.com/go-sql-driver/mysql"
   )
   
   // 初始化数据库连接
   func initDB() *sql.DB {
    db, err := sql.Open("mysql", "root:password@tcp(127.0.0.1:3306)/complaint")
    if err != nil {
        panic(err)
    }
    return db
   }
   
   // 投诉信息保存到数据库
   func saveComplaintToDB(complaint Complaint) {
    db := initDB()
    defer db.Close()
   
    stmt, err := db.Prepare("INSERT INTO complaint(content, order_id) VALUES(?, ?)")
    if err != nil {
        panic(err)
    }
   
    _, err = stmt.Exec(complaint.Content, complaint.OrderID)
    if err != nil {
        panic(err)
    }
   }

3. Staff Processing Module

   // 获取投诉列表
   func getComplaintList() []Complaint {
    db := initDB()
    defer db.Close()
   
    rows, err := db.Query("SELECT content, order_id FROM complaint")
    if err != nil {
        panic(err)
    }
    defer rows.Close()
   
    var complaintList []Complaint
   
    for rows.Next() {
        var complaint Complaint
        err := rows.Scan(&complaint.Content, &complaint.OrderID)
        if err != nil {
            panic(err)
        }
        complaintList = append(complaintList, complaint)
    }
   
    return complaintList
   }
   
   // 回复顾客投诉
   func replyComplaint(content string, orderID string) {
    // 根据订单ID查询顾客信息
    // ...
   
    // 根据顾客信息发送回复，如邮件、短信等
    // ...
   }

4. Administrator management module

   // 统计投诉数量
   func countComplaint() int {
    db := initDB()
    defer db.Close()
   
    var count int
    err := db.QueryRow("SELECT COUNT(*) FROM complaint").Scan(&count)
    if err != nil {
        panic(err)
    }
   
    return count
   }
   
   // 根据投诉内容搜索投诉信息
   func searchComplaint(keyword string) []Complaint {
    db := initDB()
    defer db.Close()
   
    rows, err := db.Query("SELECT content, order_id FROM complaint WHERE content LIKE ?", "%"+keyword+"%")
    if err != nil {
        panic(err)
    }
    defer rows.Close()
   
    var complaintList []Complaint
   
    for rows.Next() {
        var complaint Complaint
        err := rows.Scan(&complaint.Content, &complaint.OrderID)
        if err != nil {
            panic(err)
        }
        complaintList = append(complaintList, complaint)
    }
   
    return complaintList
   }

IV. Summary
This article introduces the implementation of the customer complaint handling function in the ordering system developed using Go language methods, and corresponding code examples are given. Through demand analysis and system design, we can easily complete the development of the complaint function. At the same time, we can further expand and optimize the code according to actual needs to provide better user experience and service quality. I hope this article can help you implement the complaint handling function when developing a food ordering system.
