}HTTP/2性能优化:
💼 生产环境建议:使用Let's Encrypt等免费SSL证书,配置自动更新,启用OCSP装订
通过本节Node.js HTTPS和HTTP/2实现的学习,你已经掌握:
A: 自签名证书适合开发环境,CA证书由权威机构签发,浏览器信任,适合生产环境。
A: 在多资源加载场景下HTTP/2更快,但单个大文件传输可能差异不大,需要根据具体场景测试。
A: 设置监控告警,使用自动化工具如Certbot定期更新证书,配置证书过期检查。
A: 当能预测客户端需要的资源时使用,如CSS、JS文件,避免推送不需要的资源。
A: 使用HTTP/2、启用GZIP压缩、优化SSL握手、使用CDN、配置适当的缓存策略。
# 问题:SSL证书配置错误
# 解决:使用OpenSSL工具诊断
# 检查证书有效性
openssl x509 -in certificate.pem -text -noout
# 验证私钥和证书匹配
openssl x509 -noout -modulus -in certificate.pem | openssl md5
openssl rsa -noout -modulus -in private-key.pem | openssl md5
# 测试SSL连接
openssl s_client -connect localhost:443 -servername localhost// 问题:HTTP/2连接失败
// 解决:添加连接诊断
function diagnoseHTTP2Connection(url) {
const http2 = require('http2');
const client = http2.connect(url);
client.on('connect', () => {
console.log('HTTP/2连接成功');
const req = client.request({ ':path': '/' });
req.on('response', (headers) => {
console.log('HTTP/2响应头:', headers);
});
