PHP钉钉开发指南

钉钉开放平台提供了丰富的API接口，允许开发者通过PHP构建与钉钉集成的应用。以下是钉钉PHP开发的核心要点和实现方法：

一、基础配置

1、获取应用凭证
在钉钉开放平台创建应用（企业内部应用或第三方应用）
获取`AppKey`和`AppSecret`
配置服务器接收钉钉回调

2、安装SDK
bash
composer require topthink/think-orm dingtalk/crypt dingtalk/oa

二、核心功能实现

1、获取Access Token
php
function getAccessToken($appKey, $appSecret) {
$url = https://oapi.dingtalk.com/gettoken?appkey={$appKey}&appsecret={$appSecret};
$response = file_get_contents($url);
$result = json_decode($response, true);
return $result['access_token'] ?? null;
}

2、用户身份验证
php
// 通过授权码获取用户信息
function getUserInfoByCode($accessToken, $code) {
$url = https://oapi.dingtalk.com/user/getuserinfo?access_token={$accessToken}&code={$code};
$response = file_get_contents($url);
return json_decode($response, true);
}

3、发送工作通知消息
php
function sendWorkNotification($accessToken, $agentId, $userIdList, $message) {
$url = https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2;
$data = [
'agent_id' = $agentId,
'userid_list' = implode(',', $userIdList),
'msg' = json_encode($message)
];

$options = [
'http' = [
'method' = 'POST',
'header' = 'Content-Type: application/json',
'content' = json_encode($data)
]
];

$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);
return json_decode($response, true);
}

// 发送文本消息示例
$message = [
'msgtype' = 'text',
'text' = ['content' = '这是一条测试消息']
];
sendWorkNotification($accessToken, $agentId, ['user1', 'user2'], $message);

4、获取部门信息
php
function getDepartmentList($accessToken, $id = null) {
$url = https://oapi.dingtalk.com/department/list;
if ($id) $url .= ?id={$id};
$url .= &access_token={$accessToken};
$response = file_get_contents($url);
return json_decode($response, true);
}

5、创建审批实例
php
function createApprovalInstance($accessToken, $agentId, $processCode, $originatorUserid, $approvers, $formContent) {
$url = https://oapi.dingtalk.com/topapi/processinstance/create;
$data = [
'agent_id' = $agentId,
'process_code' = $processCode,
'originator_user_id' = $originatorUserid,
'approvers' = $approvers,
'form_component_values' = $formContent
];

$options = [
'http' = [
'method' = 'POST',
'header' = 'Content-Type: application/json',
'content' = json_encode($data)
]
];

$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);
return json_decode($response, true);
}

三、接收钉钉回调

1、回调服务器配置
php
// 验证签名
function verifySignature($token, $timestamp, $signature, $encrypt) {
$signatureArray = [$token, $timestamp, $encrypt];
sort($signatureArray, SORT_STRING);
$signatureString = implode('', $signatureArray);
return sha1($signatureString) === $signature;
}

// 处理回调
function handleCallback($token, $aesKey, $signature, $timestamp, $nonce, $encrypt) {
if (!verifySignature($token, $timestamp, $signature, $encrypt)) {
return ['errcode' = 400, 'errmsg' = '签名验证失败'];
}

$aes = new Prpcrypt($aesKey);
$result = $aes-DecryptMsg($signature, $timestamp, $nonce, $encrypt);
$data = json_decode($result['message'], true);

// 处理不同类型的回调事件
switch ($data['EventType']) {
case 'user_add_org':
// 处理新增用户回调
break;
case 'bpms_instance_change':
// 处理审批回调
break;
// 其他事件类型...
}

return ['errcode' = 0, 'errmsg' = 'success'];
}

2、回调路由示例
php
// 在Laravel或ThinkPHP中定义路由
Route::post('/dingtalk/callback', function () {
$token = config('dingtalk.token');
$aesKey = config('dingtalk.aes_key');
$signature = request('signature');
$timestamp = request('timestamp');
$nonce = request('nonce');
$encrypt = request('encrypt');

return handleCallback($token, $aesKey, $signature, $timestamp, $nonce, $encrypt);
});

四、安全注意事项

1、HTTPS强制要求：所有回调接口必须使用HTTPS
2、签名验证：每次接收回调必须验证签名
3、敏感信息加密：回调消息使用AES加密
4、频率限制：注意钉钉API调用频率限制
5、错误处理：完善的错误日志记录机制

五、常见问题解决

1、获取用户信息失败
检查应用权限配置
确认用户是否已授权
验证code是否有效

2、消息发送失败
检查agent_id是否正确
确认用户是否在应用可见范围内
检查消息格式是否符合规范

3、回调接收不到
确认服务器外网可访问
检查回调URL配置是否正确
验证签名加密参数

六、官方资源

[钉钉开放平台](https://open.dingtalk.com/)
[PHP SDK文档](https://open-doc.dingtalk.com/microapp/serverapi2/krgddi)
[API调试工具](https://open-dev.dingtalk.com/tools)

通过以上指南，您可以快速搭建与钉钉集成的PHP应用，实现消息通知、审批流程、用户管理等核心功能。开发过程中建议结合钉钉官方文档和SDK进行更深入的学习。
