DingTalk Interface and PHP Mobile Conference Application Development Guide

Mobile Conference Application Development Guide for DingTalk Interface and PHP

With the rapid development of the mobile Internet, mobile office has become one of the most common office methods in modern enterprises. As the leading mobile office platform in China, DingTalk provides enterprises with a wealth of interfaces and development tools, allowing them to develop their own applications based on the DingTalk platform to meet more personalized and professional needs. This article will focus on how to use the DingTalk interface and PHP language to develop a mobile conference application.

First, we need to create a new application on the DingTalk development platform. During the creation process, we need to select the application type as mobile application and select the corresponding permission scope so that we can call the interface provided by DingTalk.

Before we start writing code, we need to obtain DingTalk’s interface call credentials (access_token), which is a key parameter for DingTalk interface calls. We can obtain it in the following ways:

<?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 {
        return false;
    }
}

$corpid = "your_corpid";
$corpsecret = "your_corpsecret";
$access_token = getAccessToken($corpid, $corpsecret);
if ($access_token) {
    echo "Access Token: " . $access_token;
} else {
    echo "Failed to get Access Token";
}
?>

After obtaining access_token, we can start writing specific function code. Assume that our mobile conference application requirements are as follows:

1. The user initiates a conference and invites specified members to participate.
2. Users can view meetings initiated and attended by themselves.
3. Users can cancel meetings initiated by themselves.
4. Users can modify the time and location of the meeting.

In order to realize the above functions, we need to use the following DingTalk interface:

• Create conference interface: Call this interface to create a new conference and invite the specified Members participate.
• Get meeting list interface: Call this interface to obtain the list of meetings initiated by the user and the list of meetings attended.
• Cancel conference interface: Call this interface to cancel a conference initiated by the user.
• Update conference interface: Call this interface to modify the time and location of the conference.

The following is a simple PHP code example to implement the above functions:

<?php
function createMeeting($access_token, $meeting) {
    $url = "https://oapi.dingtalk.com/topapi/v2/meeting/create?access_token={$access_token}";
    $data = [
        'start_time' => $meeting['start_time'],
        'end_time' => $meeting['end_time'],
        'title' => $meeting['title'],
        'location' => $meeting['location'],
        'attendees' => $meeting['attendees']
    ];
    $options = [
        'http' => [
            'method' => 'POST',
            'header' => 'Content-Type: application/json',
            'content' => json_encode($data)
        ]
    ];
    $context = stream_context_create($options);
    $response = file_get_contents($url, false, $context);
    $result = json_decode($response, true);
    if ($result['errcode'] == 0) {
        return true;
    } else {
        return false;
    }
}

function getMeetingList($access_token, $userid) {
    $url = "https://oapi.dingtalk.com/topapi/v2/meeting/list?access_token={$access_token}&userid={$userid}";
    $response = file_get_contents($url);
    $result = json_decode($response, true);
    if ($result['errcode'] == 0) {
        return $result['result']['list'];
    } else {
        return false;
    }
}

function cancelMeeting($access_token, $meeting_id) {
    $url = "https://oapi.dingtalk.com/topapi/v2/meeting/update?access_token={$access_token}";
    $data = [
        'meeting_id' => $meeting_id,
        'status' => 2
    ];
    $options = [
        'http' => [
            'method' => 'POST',
            'header' => 'Content-Type: application/json',
            'content' => json_encode($data)
        ]
    ];
    $context = stream_context_create($options);
    $response = file_get_contents($url, false, $context);
    $result = json_decode($response, true);
    if ($result['errcode'] == 0) {
        return true;
    } else {
        return false;
    }
}

function updateMeeting($access_token, $meeting) {
    $url = "https://oapi.dingtalk.com/topapi/v2/meeting/update?access_token={$access_token}";
    $data = [
        'meeting_id' => $meeting['meeting_id'],
        'start_time' => $meeting['start_time'],
        'end_time' => $meeting['end_time'],
        'title' => $meeting['title'],
        'location' => $meeting['location']
    ];
    $options = [
        'http' => [
            'method' => 'POST',
            'header' => 'Content-Type: application/json',
            'content' => json_encode($data)
        ]
    ];
    $context = stream_context_create($options);
    $response = file_get_contents($url, false, $context);
    $result = json_decode($response, true);
    if ($result['errcode'] == 0) {
        return true;
    } else {
        return false;
    }
}

// 调用示例
$corpid = "your_corpid";
$corpsecret = "your_corpsecret";
$access_token = getAccessToken($corpid, $corpsecret);

$meeting = [
    'start_time' => "2022-01-01 09:00:00",
    'end_time' => "2022-01-01 10:00:00",
    'title' => "公司年会",
    'location' => "大会议室",
    'attendees' => [ "user1", "user2" ]
];

if (createMeeting($access_token, $meeting)) {
    echo "会议创建成功";
} else {
    echo "会议创建失败";
}

$userid = "your_userid";
$meetingList = getMeetingList($access_token, $userid);
if ($meetingList) {
    foreach ($meetingList as $meeting) {
        echo "会议ID：" . $meeting['meeting_id'] . "，标题：" . $meeting['title'] . "，时间：" . $meeting['start_time'] . " - " . $meeting['end_time'] . "，地点：" . $meeting['location'] . "<br>";
    }
} else {
    echo "获取会议列表失败";
}

$meeting_id = "your_meeting_id";
if (cancelMeeting($access_token, $meeting_id)) {
    echo "会议取消成功";
} else {
    echo "会议取消失败";
}

$meeting = [
    'meeting_id' => "your_meeting_id",
    'start_time' => "2022-01-01 10:00:00",
    'end_time' => "2022-01-01 11:00:00",
    'title' => "公司年会（修改后）",
    'location' => "小会议室"
];

if (updateMeeting($access_token, $meeting)) {
    echo "会议更新成功";
} else {
    echo "会议更新失败";
}
?>

The above code example demonstrates how to use DingTalk’s interface and PHP language to develop a simple mobile app Meeting application. Developers can further expand and optimize the code according to their own needs. At the same time, the DingTalk development platform provides detailed interface documents and sample codes for developers to refer to and learn from. I hope this article will be helpful to the development of mobile conference applications using DingTalk interface and PHP.
