How PHP and UniApp implement data permission review and approval

With the continuous development of information systems, many companies and organizations are facing the need for data permission review and approval. In this article, we will discuss how to use PHP and UniApp to implement data permission review and approval.

1. Data permission audit

Data permission audit refers to the permission verification and control of data to ensure that only authorized users can access and operate the corresponding data. In PHP, data permission auditing can be achieved through the use of databases and access control lists (ACLs).

First, you need to create an ACL table to store user permission information. The ACL table can contain fields such as user ID, resource ID, and permissions. Here is an example of a simple ACL table:

ACL table:

+----+---------+------+----------+ | ID | User ID | Role | Resource | +----+---------+------+----------+ | 1 | 10001 | admin| data | | 2 | 10002 | user | data | +----+---------+------+----------+

Next, we can use a function in PHP to check if a user has specific permissions for a resource. The following is an example of a simple PHP function:

function check_permission($user_id, $resource, $permission) { // 连接数据库 $conn = mysqli_connect("localhost", "username", "password", "database"); // 查询用户的权限 $query = "SELECT Role FROM ACL WHERE User_ID = $user_id AND Resource = '$resource'"; $result = mysqli_query($conn, $query); $row = mysqli_fetch_assoc($result); // 检查用户权限 if ($row['Role'] == 'admin' || $row['Role'] == $permission) { return true; } else { return false; } }

When using this function, you only need to pass in the user ID, resource name and permission name to check whether the user has the corresponding permissions. For example:

$user_id = 10001; $resource = 'data'; $permission = 'write'; if (check_permission($user_id, $resource, $permission)) { // 用户具有写权限 // 执行相应的操作 } else { // 用户没有写权限 // 返回相应的错误提示 }

2. Data permission approval

Data permission approval refers to the approval of permission requests submitted by users to decide whether to grant the corresponding permissions to the user. In UniApp, data permission approval can be achieved by utilizing databases and message notifications.

First, you need to create an approval table to store the user's permission request information. The approval table can contain fields such as request ID, user ID, resource ID, permissions and status. The following is an example of a simple approval form:

Approval form:

+----+---------+------+----------+--------+ | ID | User ID | Role | Resource | Status | +----+---------+------+----------+--------+ | 1 | 10003 | user | data | pending| | 2 | 10004 | user | data | approved| +----+---------+------+----------+--------+

Next, you can use a page in UniApp to display the user's permission request and approval status. Users can submit permission requests by filling out a form. The following is an example of a simple UniApp page:

In this UniApp page, the user can fill in the corresponding permission request information and click the submit button to submit the request. The background needs to use PHP to process the request and store the request information in the approval table.

In PHP, you can use the relevant operation functions of the database to handle user permission requests. The following is an example of a simple PHP function:

function submit_request($user_id, $resource, $permission) { // 连接数据库 $conn = mysqli_connect("localhost", "username", "password", "database"); // 将请求插入审批表 $query = "INSERT INTO Approvals (User_ID, Resource, Permission, Status) VALUES ($user_id, '$resource', '$permission', 'pending')"; mysqli_query($conn, $query); }

In the UniApp page, we can submit a permission request by calling this PHP function. For example:

submit_request(user_id, resource, permission) { // 发送请求到PHP后端 // 提交权限请求信息 wx.request({ url: 'http://localhost/submit_request.php', method: 'POST', data: { user_id: user_id, resource: resource, permission: permission }, success: function(res) { // 提交成功 // 更新requests数组 }, fail: function(res) { // 提交失败 // 返回相应的错误提示 } }); }

In the PHP background, we need to process this request and store the corresponding permission request information into the approval table. For example:

$user_id = $_POST['user_id']; $resource = $_POST['resource']; $permission = $_POST['permission']; submit_request($user_id, $resource, $permission);

Summary:

Through the combination of PHP and UniApp, we can well implement data permission review and approval. In terms of data permission auditing, we can use databases and ACL tables to implement permission verification and control. In terms of data permission approval, we can use the database and message notification mechanism to process the user's permission request and conduct corresponding approval. The above example code can provide readers with a preliminary idea, and readers can make appropriate adjustments and optimizations according to actual needs.
