Teach you how to use PHP and Vue.js to develop applications that protect against sensitive data tampering

In order to protect sensitive data from malicious tampering, it is very important to develop a powerful application. In this article, I will teach you how to use PHP and Vue.js to develop a defensive application that protects your data from the risk of tampering.

1. Background knowledge

Before we begin, let us first understand some basic concepts.

1. PHP
   PHP is an open source server-side scripting language that can be mixed with HTML to create dynamic web pages. We will use PHP to write server-side code to process and validate user-submitted data.
2. Vue.js
   Vue.js is a popular JavaScript framework for building user interfaces. We will use Vue.js to build a responsive front-end application for rendering and displaying data.
3. Data Storage and Transfer
   We will use MySQL as our database and PHP to interact with the database. In order to ensure the security of data transmission, we will use HTTPS to encrypt data transmission.

2. Create a database table

First, we need to create a database table to store our sensitive data. Create a database named "sensitive_data" and create a table named "users" in it to store users' sensitive data. The table structure is as follows:

CREATE TABLE `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `email` varchar(255) NOT NULL,
  `password` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

3. Configure PHP and Vue.js

1. PHP configuration

In the PHP configuration, we will include the database connection information , and write some functions for processing and validating data. Create a file called "config.php" and paste the following code into it:

<?php
// 数据库连接信息
define('DB_HOST', 'localhost');
define('DB_NAME', 'sensitive_data');
define('DB_USER', 'your_username');
define('DB_PASSWORD', 'your_password');

// 连接到数据库
$conn = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

// 验证用户输入的函数
function validateInput($input) {
  // 执行你的验证逻辑，确保数据的完整性和正确性
}

// 插入数据到数据库函数
function insertData($name, $email, $password) {
  global $conn;

  $stmt = $conn->prepare("INSERT INTO users (name, email, password) VALUES (?, ?, ?)");
  $stmt->bind_param("sss", $name, $email, $password);

  if ($stmt->execute()) {
    return true;
  } else {
    return false;
  }
}
?>

2. Vue.js Configuration

In the Vue.js configuration, We will use the axios library to send requests to the server and Vue.js components to render and process the data. Create a file called "app.js" and paste the following code into it:

import Vue from 'vue';
import axios from 'axios';

// 执行一些全局配置，例如设置axios的默认baseURL等
axios.defaults.baseURL = 'http://localhost:8888';
Vue.prototype.$http = axios;

new Vue({
  el: '#app',
  data: {
    name: '',
    email: '',
    password: ''
  },
  methods: {
    submitForm() {
      this.$http.post('/saveData.php', {
        name: this.name,
        email: this.email,
        password: this.password
      })
      .then(response => {
        console.log(response);
        // 在这里可以处理服务器的响应，例如显示成功消息等
      })
      .catch(error => {
        console.log(error);
      });
    }
  }
});

4. Write PHP and Vue.js code

Now, we have configured PHP and Vue.js, we can start writing real code.

1. PHP Code

Create a file called "saveData.php" and paste the following code into it:

<?php
require_once 'config.php';

$data = $_POST;

// 对用户输入进行验证
if (!validateInput($data['name']) || !validateInput($data['email']) || !validateInput($data['password'])) {
  $response = array(
    'status' => 'error',
    'message' => 'Invalid input data'
  );
} else {
  // 插入数据到数据库
  $name = $data['name'];
  $email = $data['email'];
  $password = $data['password'];

  if (insertData($name, $email, $password)) {
    $response = array(
      'status' => 'success',
      'message' => 'Data saved successfully'
    );
  } else {
    $response = array(
      'status' => 'error',
      'message' => 'Failed to save data'
    );
  }
}

header('Content-Type: application/json');
echo json_encode($response);
?>

2. Vue.js code

In the Vue.js code, we will use the form and input components to receive and process user input. Create a file called "index.html" and paste the following code into it:

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>防御敏感数据篡改的应用程序</title>
</head>
<body>
  <div id="app">
    <form @submit.prevent="submitForm">
      <label for="name">Name</label>
      <input type="text" id="name" v-model="name">

      <label for="email">Email</label>
      <input type="email" id="email" v-model="email">

      <label for="password">Password</label>
      <input type="password" id="password" v-model="password">

      <button type="submit">Save</button>
    </form>
  </div>

  <script src="https://cdn.jsdelivr.net/npm/vue"></script>
  <script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
  <script src="app.js"></script>
</body>
</html>

5. Run the application

Now that we have completed the development of the application, we The application can be launched by running the following command in the terminal:

php -S localhost:8888

Then, access the application by visiting "http://localhost:8888" in the browser.

6. Summary

It is not difficult to develop an application with the function of preventing sensitive data tampering using PHP and Vue.js. By using appropriate validation rules and ensuring secure transmission and storage of data, we can ensure our sensitive data is protected from the risk of tampering.

In this article, we learned how to develop a basic application using PHP and Vue.js, and provided PHP and Vue.js code examples for reference. I hope this tutorial is helpful to you, and I wish you successful development!
