例 1:
index . js
// Node.js program to demonstrate the
// x509.checkIP() APi
// Importing crypto module
const {X509Certificate} = require('crypto')
// Importing fs module
const fs = require('fs')
// getting object of a PEM encoded X509 Certificate.
const x509 = new X509Certificate(fs.readFileSync('public-cert.pem'));
// checking if passed ip address matches with the given one or not
// by using x509.checkIP() api
const value = x509.checkIP("2409:4060:2e05:28d2:d02:7717:820b:22ef")
// display the result
if(value)
console.log("IP address matched")
else
console.log("IP address did't match")
使用以下命令运行 index.js 文件。
node index.js
输出:
IP address did't match
