1.下载安装openssl（用于生成秘钥颁发证书）

mac自带

window：https://slproweb.com/products/Win32OpenSSL.html

2.生成CA证书，CA钥和CA公钥

生成CA私钥,并用des3算法进行加密：openssl genrsa -des3 -out ca-pri-key.pem 1024

生成CA公钥：openssl req -new -key ca-pri-key.pem -out ca-pub-key.pem

生成CA证书：openssl x509 -req -in ca-pub-key.pem -signkey ca-pri-key.pem -out ca-cert.crt

3.生成服务器公钥私钥

生成服服务私钥：openssl genrsa -out server-key.pem 1024

生成服务器公钥：openssl req -new -key server-key.pem -out server-scr.pem

4.机构颁发证书

openssl x509 -req -CA ca-cert.crt -CAkey ca-pri-key.pem -CAcreateserial -in server-scr.pem -out server-cert.crt

5.https配置

const http = require("https");
const url = require("url");
const path = require("path");
const fs = require("fs");

/**
 * 返回文件状态
 * @param {*} filename 
 * @returns 
 */
async function getStat(filename) {
    try {
        return await fs.promises.stat(filename);
    } catch {
        return null;
    }
}

/**
 * 得到要处理的文件内容
 */
async function getFileContent(url1) {
    const urlObj = url.parse(url1);
    let filename; //要处理的文件路径
    filename = path.resolve(__dirname, "public", urlObj.pathname.substr(1));//得到请求文件路径
    let stat = await getStat(filename); //得到文件状态

    if (!stat) {
        //文件不存在
        return null;
    } else if (stat.isDirectory()) {
        //文件是一个目录
        filename = path.resolve(
            __dirname,
            "public",
            urlObj.pathname.substr(1),
            "index.html"
        );
        stat = await getStat(filename);  //重新获取index.html文件状态

        if (!stat) {
            return null;
        } else {
            return await fs.promises.readFile(filename);  //返回文件
        }
    } else {
        return await fs.promises.readFile(filename); //不是目录返回文件
    }
}


const server = http.createServer({
    key:fs.readFileSync(path.resolve(__dirname,"./server-key.pem")),
    cert:fs.readFileSync(path.resolve(__dirname,"./server-cert.crt"))
},async (req, reps) => {
    const url = req.url;
    const content = await getFileContent(url);
    if (content) {
        reps.write(content);
    }else{
        reps.statusCode = 404;
        reps.write("Not Found");
    }
    reps.end();
})

server.listen(443);
server.on("listening", () => {
    console.log("监听端口443");
})
