Encryption and decryption methods of routing parameters in uniapp

The encryption and decryption method of routing parameters in uniapp requires specific code examples

[Introduction]
In uniapp development, we often encounter a The situation is that some sensitive information needs to be passed through routing, but the parameters passed are in clear text, which poses certain security risks. In order to protect the security of user data, we can encrypt and decrypt routing parameters to increase data security. This article will introduce the encryption and decryption methods of routing parameters in uniapp, and provide practical code examples.

[Encryption method]
In uniapp, common encryption algorithms (such as AES, RSA, etc.) can be used to encrypt the passed parameters to protect the security of the data. The following uses the AES algorithm as an example to introduce encryption methods and code examples.

1. Installation dependencies
   In the root directory of the uniapp project, open the command line tool and execute the following command to install the crypto-js library.

npm install crypto-js

2. Import and configure the encryption library
   Introduce the crypto-js library into the page that needs to be encrypted, and configure the encryption key.

// 引入加密库
import CryptoJS from 'crypto-js'

// 配置加密密钥
const secretKey = '1234567890123456' // 密钥长度为16字节（128位）

3. Encrypt parameters and pass parameters
   In the page where parameters need to be passed, use the encryption library to encrypt the parameters and pass them through routing.

// 加密参数
const plainText = '要传递的参数'
const cipherText = CryptoJS.AES.encrypt(plainText, secretKey).toString()

// 通过路由传递加密后的参数
uni.navigateTo({
  url: `../targetPage/targetPage?param=${encodeURIComponent(cipherText)}`
})

[Decryption method]
In the target page, the encrypted parameters need to be decrypted to obtain the real parameter values. The following uses the AES algorithm as an example to introduce the decryption method and code examples.

1. Import and configure the decryption library
   In the target page, introduce the crypto-js library and configure the decryption key.

// 引入解密库
import CryptoJS from 'crypto-js'

// 配置解密密钥
const secretKey = '1234567890123456' // 密钥长度为16字节（128位）

2. Decryption parameters
   In the onLoad life cycle method of the target page, obtain the parameters passed by the route and decrypt them.

onLoad(options) {
  // 获取加密后的参数
  const cipherText = options.param

  // 解密参数
  const bytes  = CryptoJS.AES.decrypt(cipherText, secretKey)
  const plainText = bytes.toString(CryptoJS.enc.Utf8)

  // 输出解密后的参数
  console.log(plainText)
}

Through the above steps, we successfully implemented the encryption and decryption functions of routing parameters in uniapp and ensured the security of sensitive information.

[Summary]
This article introduces the encryption and decryption methods of routing parameters in uniapp, and provides specific code examples of the AES algorithm. In actual development, we can choose an appropriate encryption algorithm based on actual needs and encrypt sensitive parameters to protect the security of user data.
