How to use Golang to implement JD Logistics interface for web applications

With the development of the e-commerce industry, logistics has increasingly become a key link. At the same time, more and more merchants are beginning to connect to JD Logistics platform. In this article, we will introduce how to use Golang to implement the JD Logistics interface for web applications.

JD Logistics Interface is an application program interface provided by JD Logistics platform. It can assist merchants to achieve a variety of business needs, including online logistics tracking, order cancellation, package receipt, etc. This time, we will focus on how to use Golang to implement JD Logistics interface.

Preparation before starting

Before starting, we need to complete the following steps:

1. Apply for the API Key and API Secret of the open interface of the JD Logistics platform.
2. Confirm the API interfaces you need to use, such as third-party order inquiry, delivery and other interfaces.
3. Install the Golang programming language and configure the development environment.

About Golang

Golang is an open source programming language developed and maintained by Google. The Golang language has good concurrency and efficient memory management capabilities, and is a programming language very suitable for building web applications.

Before you start using Golang to implement the JD Logistics interface, you need to understand some basic knowledge of Golang, such as syntax, variables, functions, etc.

Implementing JD Logistics Interface

Below we will use a simple example to demonstrate how to use Golang to implement JD Logistics Interface. In this example, we will use the JD Logistics third-party order query API interface.

1. Create a toolkit named "jdeutil" and create an initialization function named "InitJdeConfig" in the toolkit.

package jdeutil

import (
   "fmt"
   "github.com/KingDomPan/jd_httpclient_go/jd"
)

func InitJdeConfig() {
   apiKey := "[您的API Key]"
   apiSecret := "[您的API Secret]"
   version := "2.0"
   jd.SetAppKey(apiKey)
   jd.SetAppSecret(apiSecret)
   jd.SetVersion(version)
   fmt.Println("初始化京东物流配置...")
}

In this function, we initialize the JD Logistics configuration by calling the SetAppKey, SetAppSecret and SetVersion methods in the jd_httpclient_go/jd package. Your actual API Key and API Secret need to be replaced in the code.

2. In the program that needs to use the JD Logistics interface, call the InitJdeConfig method to initialize the JD Logistics configuration.

package main

import "jdeutil"

func main() {
   jdeutil.InitJdeConfig()
   // 其他代码
}

3. Call JD Logistics API interface in the program.

package main

import (
   "fmt"
   "jdeutil"
)

func main() {
   jdeutil.InitJdeConfig()

   result, err := jd.GetOrderTracesByJson("[快递公司编码]", "[快递单号]")
   if err != nil {
       fmt.Println(err)
       return
   }
   fmt.Println(result)
}

In the above code, we call the GetOrderTracesByJson method in the jd_httpclient_go/jd package to obtain the logistics tracking information of the specified express delivery number. You need to replace your actual courier company code and courier tracking number into the code.

The above are the basic ideas and steps for using Golang to implement JD Logistics interface. It should be noted that when using the JD Logistics interface, you need to comply with the usage specifications of the JD Logistics platform.

Summary

This article introduces how to use Golang to implement the JD Logistics interface of web applications. First, we need to understand the basic knowledge of Golang and the API interface documentation of JD Logistics Platform. Then, we need to create a toolkit named "jdeutil" and create an initialization function in the toolkit to initialize the JD Logistics configuration. Finally, in the program that needs to use the JD Logistics interface, we call the initialization function to initialize the JD Logistics configuration, and then call the API interface to obtain the corresponding data.
