Analysis of Vue and server-side communication: ensuring data security

Vue server-side communication inherited from the front-end framework Vue.js is a commonly used web development technology , providing developers with a more efficient and secure way to interact with data. In this article, we will delve into the mechanism of Vue and server-side communication, focusing on how to ensure data security.

Usually, Vue communicates with the server through the HTTP protocol to obtain or submit data. To ensure the security of data transmission, we need to take the following key steps.

Step one: Use HTTPS protocol for data transmission

Using HTTPS protocol is the most basic requirement to ensure the security of data transmission. It adds the SSL/TLS protocol on the basis of the HTTP protocol to protect sensitive information by encrypting the transmitted data. In Vue, you can use the axios library to send HTTPS requests.

The following is an example of using axios to send HTTPS requests:

import axios from 'axios';

axios.get('https://api.example.com/data')
  .then(response => {
    // 处理返回的数据
  })
  .catch(error => {
    // 处理错误
  });

In the actual project, we need to obtain the SSL certificate provided by the server and configure the certificate into the Vue application.

Step 2: Verify the server-side certificate

In order to prevent man-in-the-middle attacks, the Vue application needs to verify the legitimacy of the server-side certificate. In Vue, you can configure the verification server certificate using webpack's https configuration.

The following is an example of verifying the server certificate in the webpack configuration file:

module.exports = {
  devServer: {
    https: {
      key: fs.readFileSync('./ssl/server.key'),
      cert: fs.readFileSync('./ssl/server.crt'),
      ca: fs.readFileSync('./ssl/rootCA.crt'),
      requestCert: true,
      rejectUnauthorized: true
    }
  }
};

key, cert and ca# in the configuration ## is the path to the server-side certificate file. requestCert is used to enable client certificate verification, rejectUnauthorized is used to reject unverified requests.

import axios from 'axios';
import jwtDecode from 'jwt-decode';

// 用户登录
axios.post('https://api.example.com/login', {
  username: 'admin',
  password: '123456'
})
  .then(response => {
    const token = response.data.token;
    // 将token保存到localStorage中
    localStorage.setItem('token', token);
  })
  .catch(error => {
    // 处理登录错误
  });

// 发送带有JWT的请求
axios.get('https://api.example.com/data', {
  headers: {
    Authorization: `Bearer ${localStorage.getItem('token')}`
  }
})
  .then(response => {
    // 处理返回的数据
  })
  .catch(error => {
    // 处理错误
  });

// JWT解码
const token = localStorage.getItem('token');
const decodedToken = jwtDecode(token);
console.log(decodedToken);

Authorization field of the request header.
