With the popularization of the Internet and the development of e-commerce, more and more traditional industries have begun to Internet transformation. The catering industry is no exception, and many restaurants are beginning to utilize ordering systems to improve efficiency and user experience. In the ordering system, the promotion function of dishes is very important to increase sales and user stickiness. This article will introduce how to use Go language to develop the dish promotion function of the ordering system and provide specific code examples.

1. The importance of dish promotion

Dish promotion refers to communicating dish information to users through reasonable methods and means, so that users become interested in the dishes and make purchases. In the catering industry, dish promotion can help restaurants increase sales and increase users' willingness to spend. Reasonable dish promotion can not only increase profits, but also enhance users' awareness and favorability of the restaurant brand.

2. Development of Go language ordering system

Go language is a concise, efficient and concurrent programming language, suitable for building large-scale distributed systems. With the help of the features of Go language, we can quickly develop an efficient and stable ordering system.

When developing the ordering system, we can use Go language web framework, such as Gin or Beego, to build back-end services. At the same time, front-end technologies such as HTML, CSS and JavaScript can be used to develop user interfaces, and the ordering function can be implemented through front-end and back-end interaction.

3. Implementation of the dish promotion function

Category display of dishes: Display dishes according to categories to provide users with a more convenient search method. You can use Go language to query different categories of dish data from the database, and render the data into the front-end page through HTML templates.
Dish recommendation: Recommend dishes that users may be interested in through algorithms or user behavior data. In the specific implementation, the user behavior data can be obtained from the backend server through the Go language, the algorithm can be used to analyze the user's preferences, and relevant dishes can be recommended to the user based on the user's preferences.
Preferential activity display: For the catering industry, discounts and promotions are common promotion methods. You can use Go language to dynamically obtain data on promotional activities and render the data into the front-end page to guide users to consume.
Dish reviews and sharing: User reputation plays a vital role in the promotion of dishes. You can use Go language to obtain the evaluation data of dishes from the database, display the evaluation data to users in an appropriate way, and encourage users to comment and share.

Code example:

The following is a sample code for a simple dish promotion function developed using Go language:

// main.go
package main

import (
    "fmt"
    "net/http"
    "html/template"
)

func main() {
    http.HandleFunc("/", indexHandler)
    http.ListenAndServe(":8080", nil)
}

func indexHandler(w http.ResponseWriter, r *http.Request) {
    data := struct {
        Dishes []string
    }{
        Dishes: []string{"红烧肉", "宫保鸡丁", "清蒸鲈鱼"},
    }

    tmpl := template.Must(template.ParseFiles("index.html"))
    err := tmpl.Execute(w, data)
    if err != nil {
        fmt.Println(err.Error())
    }
}

<!-- index.html -->
<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>菜品推广</title>
</head>
<body>
    <h1>菜品推广</h1>
    <ul>
        {{range $index, $dish := .Dishes}}
            <li>{{$dish}}</li>
        {{end}}
    </ul>
</body>
</html>

In the above example, through ## The #http.HandleFunc function routes the request to the indexHandler function. In the indexHandler function, we define a data structure that contains dish information. Use the template.Must(template.ParseFiles("index.html")) function to parse the HTML template file, and render the parsed template and data data. Finally, use tmpl.Execute(w, data) to send the rendered template to the client.

4. Summary

The dish promotion function is an important part of the ordering system, which can help restaurants increase dish sales and enhance user experience. This article introduces how to use Go language to develop the dish promotion function of the ordering system, and provides specific code examples. Through reasonable design and development, an efficient and stable ordering system can be realized, which will bring great help to the operation of the restaurant.
