Go language development of door-to-door cooking system: How to implement user preference setting function?

As people pay more and more attention to healthy eating, the demand for dining out is also increasing. To meet this demand, door-to-door cooking services emerged. The door-to-door cooking system facilitates users' appetite by sending chefs to users' homes to cook delicious dishes for them. As a modern system, the user preference setting function is essential.

There are many ways to implement user preference settings in the Go language. The following is a possible implementation:

1. Database design
   First, we need to design a database to Stores the user's preferences. You can create a table named "preferences", which contains the following fields:
2. User ID (userID): an ID used to uniquely identify the user
3. Category Preference (categoryPreference): The user's preference Preferences for different food categories, such as Sichuan cuisine, Cantonese cuisine, etc.
4. Spice Level Preference (spiceLevelPreference): User's preference for spiciness, such as not spicy, slightly spicy, medium spicy, etc.
5. Sour and sweetness Preference (sweetnessPreference): User's preference for sweetness and sourness, such as sourness, sweetness, etc.
6. User registration and login
   In the door-to-door cooking system, users need to register and log in to use the preference setting function . You can use third-party libraries (such as gin) to quickly implement user registration and login functions. After a user successfully registers, we can create a record for them in the database and default their preferences to the average.
7. Implement user preference setting interface
   Through the HTTP interface, users can modify their preferences. We can use the gin framework to handle routing. Here is a sample code snippet:

package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

// 定义偏好设置结构体
type Preference struct {
    Category   string `json:"category"`
    SpiceLevel string `json:"spice_level"`
    Sweetness  string `json:"sweetness"`
}

// 处理偏好设置请求
func handlePreference(c *gin.Context) {
    // 解析请求体中的JSON数据
    var preference Preference
    if err := c.ShouldBindJSON(&preference); err != nil {
        c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
        return
    }

    // 获取用户ID
    userID := c.Param("userID")

    // TODO: 将偏好设置更新到数据库中

    c.JSON(http.StatusOK, gin.H{"message": "Preference updated successfully"})
}

func main() {
    // 创建一个HTTP路由器
    router := gin.Default()

    // 处理偏好设置请求的路由
    router.PUT("/users/:userID/preference", handlePreference)

    // 启动HTTP服务器
    router.Run(":8080")
}

In the above code, we define a preference structure to receive JSON data in the request body. Then, a PUT route was created using the gin framework to handle preference requests. In the route handler function, we can get the user ID from the path parameter and update the preferences to the database.

4. Using user preferences
   Through user preferences, we can provide users with more personalized door-to-door cooking services. For example, in the menu display interface, we can recommend more preferred dishes to users based on their dish category preferences. At the same time, we can also adjust the taste of the dishes according to the user's spiciness preference and sweetness and sourness preference to meet the user's taste needs.

Summary:
The above is an example of using Go language to implement the user preference setting function in the door-to-door cooking system. By storing user preferences in the database, combined with HTTP interfaces and frameworks, we can provide users with more personalized services. Of course, we can also optimize and expand the code according to actual needs.
