What are the innovations in using the Go language to develop the delivery person check-in function of the door-to-door cooking system?

With the rapid development of the takeout industry, door-to-door cooking services have become an increasingly popular choice in daily life. In order to provide a better user experience and improve delivery efficiency, the development of door-to-door cooking systems must have innovative delivery staff check-in functions. This article will explore the innovation of using Go language to develop this function and provide specific code examples.

1. Multi-terminal support

The delivery person check-in function of the traditional door-to-door cooking system usually only supports operation on the mobile phone. By using the Go language for development, we can easily achieve multi-terminal support, including mobile phones, tablets, and computers. In this way, the delivery person can complete the check-in operation on a more convenient device, improving the flexibility and convenience of the operation.

Sample code:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintln(w, "配送员签到功能")
}

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

2. Real-time positioning

The delivery person check-in function of the traditional door-to-door cooking system usually only displays the approximate location of the delivery person and cannot provide accurate real-time information. Positioning information. Developed using Go language, it can be combined with third-party map API to achieve real-time positioning function. In this way, users and administrators can accurately understand the location of the delivery person, make preparations in advance, and ensure that the dishes are delivered on time.

Sample code:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    // 获取配送员的实时定位信息
    location := GetDriverLocation(driverID)
  
    fmt.Fprintln(w, "配送员实时定位：", location)
}

func GetDriverLocation(driverID int) string {
    // 调用第三方地图API获取配送员的实时定位信息
    // ...
    return "xxx"
}

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

3. Electronic signature

The delivery person’s check-in function of the traditional door-to-door cooking system usually requires the delivery person to sign on the paper for confirmation. Using Go language development, we can implement the electronic signature function, so that delivery personnel can sign and confirm on their mobile phones or tablets, avoiding the waste of paper and the inconvenience of handwritten signatures.

Sample code:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    // 显示需要进行电子签名的订单信息
    fmt.Fprintln(w, "订单信息：", orderInfo)
}

func signHandler(w http.ResponseWriter, r *http.Request) {
    // 处理电子签名请求
    if r.Method == "POST" {
        // 解析签名信息
        signInfo := parseSignInfo(r.Body)
      
        // 将签名信息保存至数据库
        saveSignInfo(signInfo)
      
        fmt.Fprintln(w, "电子签名成功")
    }
}

func parseSignInfo(body []byte) SignInfo {
    // 解析签名信息
    // ...
    return signInfo
}

func saveSignInfo(signInfo SignInfo) {
    // 保存签名信息至数据库
    // ...
}

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

Use Go language to develop the delivery person check-in function of the door-to-door cooking system, which can realize innovations such as multi-terminal support, real-time positioning and electronic signatures. This will provide users with a better experience while improving delivery efficiency and service quality. We believe that with the continuous advancement of technology, door-to-door cooking systems will become more and more intelligent, bringing users a more convenient lifestyle.
