nodejs中https和ca证书

绝大部分demo和姿势都可以在nodejs官网查看到。可以多多查阅

自签名的证书生成（不推荐2333）

openssl genrsa -out server.key 2048//这是秘钥
openssl req -new -sha256 -key server.key -out csr.pem//这好像是签名请求？没在意 
openssl x509 -req -in csr.pem -signkey server.key -out cert.pem//这是证书

以下代码来自官网demo改编

https 服务器端 servers

// curl -k https://localhost:8000/

const https = require('https');
const fs = require('fs');

const options = {
    key: fs.readFileSync('./ssl/server.pem'),//这是我在ssl目录下生成的server.key改名为server.pem
    cert: fs.readFileSync('./ssl/cert.pem'),

    requestCert:true,  //请求客户端证书

    rejectUnauthorized:false //如果没有请求到客户端来自信任CA颁发的证书，拒绝客户端的连接
};

https.createServer(options, (req, res) => {
    res.writeHead(200);
    console.log(req);
    console.log(typeof req);
    console.log(req.method);
    res.end('hello world\n');
}).listen(9000);

console.log("server https is running 9000");

//接下来是https post请求demo 以验证证书，其实可以此时可以用浏览器访问你的端口，注意看浏览器栏，左边一般有个红色三角感叹号，那就是说有个证书，但是证书不规范233

//以下程序也来自官方demo改编

const https = require('https');
const fs = require('fs');
const querystring = require("querystring");


const postData = querystring.stringify({
    'msg': 'Hello World!'
});


const options = {
    hostname: '127.0.0.1',
    port: 9000,
    path: '/',
    method: 'POST',
    requestCert:true,  //请求客户端证书
    rejectUnauthorized: false, //不拒绝不受信任的证书
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(postData)
    }
};


const req = https.request(options, (res) => {
    console.log(`STATUS: ${res.statusCode}`);
    console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
    res.setEncoding('utf8');
    res.on('data', (chunk) => {
        console.log(`BODY: ${chunk}`);
    });
    res.on('end', () => {
        console.log('No more data in response.');
    });
});


req.on('error', (e) => {
    console.error(`problem with request: ${e.message}`);
});


// write data to request body
req.write(postData);
req.end();
