Meeting Booking Application Development Guide for DingTalk Interface and PHP

Introduction:
With the popularization of mobile office and the advancement of enterprise digitization, meeting booking applications have become one of the indispensable tools for enterprises. As the leading enterprise-level communication and collaboration platform in China, DingTalk’s open interface provides developers with great convenience. This article will introduce how to use the DingTalk interface and PHP to develop a simple but practical conference booking application.

1. Register a developer account and create an application
   Before starting development, we need to go to the DingTalk open platform to register a developer account and create a new application. After logging in to your developer account, select "Application Development" in the console, then click "Create Application" and fill in the corresponding application information. After successful creation, the system will automatically generate a CorpId and CorpSecret for us. These two parameters will be used in subsequent development.
2. Get access_token
   Every time you call the DingTalk interface, you need to carry a valid access_token for identity verification. We can use CorpId and CorpSecret to obtain access_token. The code example is as follows:

<?php
function getAccessToken($corpId, $corpSecret) {
    $url = "https://oapi.dingtalk.com/gettoken?corpid={$corpId}&corpsecret={$corpSecret}";
    $response = file_get_contents($url);
    $result = json_decode($response, true);

    if ($result['errcode'] == 0) {
        return $result['access_token'];
    } else {
        throw new Exception('Failed to get access token. Error code: ' . $result['errcode'] . ', error message: ' . $result['errmsg']);
    }
}

// 使用自己的CorpId和CorpSecret调用该函数获取access_token
$accessToken = getAccessToken($corpId, $corpSecret);

3. Create a conference room
   In the conference booking application, we need to first create a conference room and set up the conference Room related properties. The following is a sample code for creating a conference room:

function createMeetingRoom($accessToken, $roomName, $capacity) {
    $url = "https://oapi.dingtalk.com/topapi/conference/room/add?access_token={$accessToken}";
    $data = array(
        "room_name" => $roomName,
        "capacity" => $capacity
    );
    $data = json_encode($data);

    $options = array(
        'http' => array(
            'method' => 'POST',
            'header' => 'Content-Type: application/json',
            'content' => $data
        )
    );
    $context = stream_context_create($options);
    $response = file_get_contents($url, false, $context);
    $result = json_decode($response, true);

    if ($result['errcode'] == 0) {
        return $result['room_id'];
    } else {
        throw new Exception('Failed to create meeting room. Error code: ' . $result['errcode'] . ', error message: ' . $result['errmsg']);
    }
}

// 创建一个名为"会议室A"，可容纳10人的会议室
$roomId = createMeetingRoom($accessToken, "会议室A", 10);

4. Booking a conference room
   After having a conference room, we can book the conference room by calling the DingTalk interface. The following is a sample code for booking a conference room:

function bookMeetingRoom($accessToken, $roomId, $startTime, $endTime, $title, $attendees) {
    $url = "https://oapi.dingtalk.com/topapi/conference/room/reserve/v2?access_token={$accessToken}";
    $data = array(
        "room_id" => $roomId,
        "schedule_start" => $startTime,
        "schedule_end" => $endTime,
        "title" => $title,
        "attendees" => $attendees
    );
    $data = json_encode($data);

    $options = array(
        'http' => array(
            'method' => 'POST',
            'header' => 'Content-Type: application/json',
            'content' => $data
        )
    );
    $context = stream_context_create($options);
    $response = file_get_contents($url, false, $context);
    $result = json_decode($response, true);

    if ($result['errcode'] == 0) {
        return $result['order_id'];
    } else {
        throw new Exception('Failed to book meeting room. Error code: ' . $result['errcode'] . ', error message: ' . $result['errmsg']);
    }
}

// 预订"会议室A"，从2022-01-01 09:00:00到2022-01-01 10:00:00，主题为"公司会议"，参与人为员工A和员工B
$orderId = bookMeetingRoom($accessToken, $roomId, "2022-01-01 09:00:00", "2022-01-01 10:00:00", "公司会议", array("员工A", "员工B"));

Summary:
Through the DingTalk interface and PHP, we can easily develop a conference booking application. Through the above code examples, we learned how to obtain the access_token, create a conference room, and reserve a conference room. I hope this article can provide some help to everyone in DingTalk interface and PHP development. Let’s use the powerful functions of DingTalk to improve the efficiency and convenience of corporate meeting management.
