DingTalk Interface and PHP Approval and Approval Application Development Guide
DingTalk is a mobile office tool widely used within enterprises. It provides a rich interface to integrate with internal systems of enterprises. . In enterprises, review and approval processes are very common workflows. By combining the DingTalk interface with PHP, you can easily develop review and approval applications to improve work efficiency. This article will introduce how to use the DingTalk interface and PHP to develop approval and approval applications, and provide relevant code examples.
1. Preparation work
Before starting development, some preparation work is required.
2. DingTalk interface and PHP integration
DingTalk provides a series of interfaces through which interaction and communication with DingTalk can be achieved. In PHP, you can use the curl function to send HTTP requests to interact with DingTalk.
When users use the DingTalk application, they need to authenticate and log in first. You can use the interface provided by DingTalk to obtain the user's authorization information.
Sample code:
<?php $appKey = 'your_app_key'; $appSecret = 'your_app_secret'; $redirectUri = 'http://your_callback_url'; $url = "https://oapi.dingtalk.com/connect/qrconnect?appid=".$appKey."&response_type=code&scope=snsapi_login&state=STATE&redirect_uri=".urlencode($redirectUri); header("Location: ".$url);
In the above code, $appKey
and $appSecret
need to be replaced with the AppKey and AppSecret of your own application, $redirectUri
needs to be replaced with the callback URL of your own application. By redirecting to the above URL through the header
function, users can authorize login in DingTalk.
Before using the DingTalk interface to perform other operations, you need to obtain the access token first. The access token is the credential for accessing the DingTalk interface.
Sample code:
<?php $appKey = 'your_app_key'; $appSecret = 'your_app_secret'; $url = "https://oapi.dingtalk.com/gettoken?appkey=".$appKey."&appsecret=".$appSecret; $result = file_get_contents($url); $data = json_decode($result, true); $accessToken = $data['access_token'];
In the above code, $appKey
and $appSecret
need to be replaced with the AppKey and AppSecret of your own application. Send an HTTP request by calling the file_get_contents
function, obtain the returned JSON data, and then parse out the access token.
3. Approval and approval application development example
The following takes a leave approval scenario as an example to demonstrate how to develop an approval and approval application.
After the user clicks the Initiate Leave button, the interface of DingTalk is called to create leave approval.
Sample code:
<?php $accessToken = 'your_access_token'; $url = "https://oapi.dingtalk.com/topapi/processinstance/create?access_token=".$accessToken; $data = array( 'app_key' => 'your_app_key', 'process_code' => 'your_process_code', 'originator_user_id' => 'your_user_id', 'dept_id' => 'your_dept_id', 'form_component_values' => array( array( 'name' => '请假类型', 'value' => '事假' ), array( 'name' => '请假时间', 'value' => '2022-01-01 09:00:00' ), array( 'name' => '请假时长', 'value' => '1小时' ), array( 'name' => '请假事由', 'value' => '生病' ) ) ); $data = json_encode($data); $ch = curl_init($url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch); curl_close($ch); $data = json_decode($result, true); $instanceId = $data['process_instance']['instance_id'];
In the above code, $accessToken
needs to be replaced with your own access token, $data
is when creating leave approval The request parameters, app_key
, process_code
, originator_user_id
, dept_id
need to be filled in according to the actual situation, form_component_values
It is the form data for leave application.
Call the curl_exec
function to send an HTTP request, and then parse the returned data to obtain the instance ID for leave approval.
After the approver receives the leave approval message in DingTalk, he or she can proceed with the approval operation.
Sample code:
<?php $accessToken = 'your_access_token'; $url = "https://oapi.dingtalk.com/topapi/processinstance/action/start?access_token=".$accessToken; $data = array( 'instance_id' => 'your_instance_id', 'userid' => 'your_user_id', 'action_type' => 'agree', 'remark' => '同意请假' ); $data = json_encode($data); $ch = curl_init($url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch); curl_close($ch); $data = json_decode($result, true); if ($data['errcode'] == 0) { echo '审批成功'; } else { echo '审批失败:'.$data['errmsg']; }
In the above code, $accessToken
needs to be replaced with your own access token, $data
is used when approving leave applications The request parameters, where instance_id
is the instance ID for leave approval, userid
is the user ID of the approver, action_type
indicates the approval operation type, remark
is the approval opinion.
Similarly call the curl_exec
function to send an HTTP request, and parse the returned data to determine whether the approval is successful.
The above sample code is for demonstration purposes only. In actual development, it needs to be adapted and expanded according to specific needs.
Summary
By combining the DingTalk interface with PHP, we can easily develop approval and approval applications and improve work efficiency. This article introduces the integration method of DingTalk interface and PHP, and provides development examples of review and approval applications. I hope this article can be helpful to developers developing DingTalk applications.
