Detailed explanation of the data transmission method between PHP and DingTalk interface

DingTalk is an enterprise-level office communication tool. It provides a rich API interface that developers can implement through DingTalk functions. Automation of enterprise offices. In PHP development, we can realize data transmission and interaction through the interface provided by DingTalk. This article will introduce in detail the data transmission method between PHP and DingTalk interface, and attach code examples.

1. Use cURL to send HTTP requests

cURL is a powerful tool for communicating with the server. We can use cURL to send HTTP requests to interact with the DingTalk interface. In PHP, you can use cURL to send a GET request through the following code:

<?php
$url = "https://api.dingtalk.com/xxx"; // 钉钉接口的请求地址
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);
$data = json_decode($response, true);
print_r($data);
?>

The above code initializes a cURL session through the curl_init function, and then sets the request options through the curl_setopt function, where the CURLOPT_RETURNTRANSFER option is used to set the returned content as string instead of outputting it directly. Finally, the curl_exec function is used to execute the request and the results are returned, and finally the json_decode function is used to parse the returned results. In this way we can get the data returned by the DingTalk interface.

2. Use HTTP request classes

In addition to using cURL, you can also use some HTTP request libraries for data requests and interactions. In PHP, common HTTP request libraries include GuzzleHttp, Curl, Requests, etc. The following takes GuzzleHttp as an example for a code example:

First, you need to use Composer to install GuzzleHttp:

$ composer require guzzlehttp/guzzle

Then, you can use the following code to make a GET request:

<?php
require 'vendor/autoload.php';
use GuzzleHttpClient;
$url = "https://api.dingtalk.com/xxx"; // 钉钉接口的请求地址
$client = new Client();
$response = $client->request('GET', $url);
$data = json_decode($response->getBody()->getContents(), true);
print_r($data);
?>

The above code First introduce the auto-loading file of GuzzleHttp, and then introduce the GuzzleHttpClient class through the use keyword. Then instantiate the Client class through the new keyword, and use the request method to send a GET request. Finally, obtain the request results through the getBody and getContents methods, and parse the data through json_decode.

3. Use SDK

If we need to simplify the operation, we can use the SDK officially provided by DingTalk for development. DingTalk provides SDKs in multiple languages, including PHP, Java, Python, etc. The following takes PHP SDK as an example to introduce how to use it:

First, you need to use Composer to install DingTalk PHP SDK:

$ composer require topthink/framework

Then, introduce the autoload.php file into your PHP code:

<?php
require 'vendor/autoload.php';

Next, you can use the following code to make a GET request:

<?php
require 'vendor/autoload.php';
use TopthinkThinkAPI;
use TopthinkThinkAPIRequest;
$appkey = "xxx"; // 应用的 appkey
$appsecret = "xxx"; // 应用的 appsecret
$request = new Request($appkey, $appsecret);
$url = "https://api.dingtalk.com/xxx"; // 钉钉接口的请求地址
$response = $request->get($url);
$data = json_decode($response->getBody(), true);
print_r($data);
?>

The above code first introduces the ThinkAPI and Request classes, instantiates the Request class, and passes in the appkey and appsecret of the application. Then send a GET request through the get method, and finally obtain the request result through the getBody method, and parse the data through json_decode.

Summary:

This article introduces in detail the data transmission method of PHP and DingTalk interface, including using cURL to send HTTP requests, using HTTP request class library and using DingTalk SDK. According to actual needs and development habits, you can choose the appropriate method to realize data transmission and interaction. The above code examples can be used as a reference to help developers better use PHP to develop integrated applications with the DingTalk interface.
