node创建http和https服务器

http服务器

 复制代码
const http = require("http");
const url = require("url");
const querystring = require("querystring");
let server = http.createServer((req, res) => {
  let pathname = url.parse(req.url).pathname;
  console.log("pathname: " + pathname);
  let body = "";
  req.on("data", (data) => {
    body += data;
  });
  req.on("end", () => {
    res.writeHead(200, { "content-type": "text/plain" });
    if (req.method === "GET") {
      let query = querystring.parse(url.parse(req.url).query);
      console.log("query:%j", query);
      res.end("http-server-get");
    } else if (req.method === "POST") {
      let query = querystring.parse(body);
      console.log("query:%j", query);
      res.end("http-server-post");
    }
  });
});
server.listen(1234, () => {
  console.log("服务器启动监听localhost:1336");
});

http客户端

 复制代码
const http = require("http");
const querystring = require("querystring");
const options = {
  hostname: "localhost",
  port: 1234,
  path: "/info/child?abc=123&name=china",
    method: "GET",
//   method: "POST",
};
const contents = querystring.stringify({
  name: "china",
  abc: 456,
});
const req = http.request(options, (res) => {
  console.log("status:" + res.statusCode);
  console.log("headers:" + res.headers);
  res.setEncoding("utf8");
  res.on("data", (data) => {
    console.log("response:" + data);
  });
});
// req.write(contents);
req.end();

https服务器

https需要访问秘钥和证书文件

安装了openssl，生成证书

 复制代码
/**
 * ssl证书生成
**/
openssl genrsa -out privatekey.pem 1024 【生成privatekey.pem私钥】
openssl req -new -key privatekey.pem -out certrequest.csr 【生成certrequest.csr签名】
openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem 【生成certificate.pem签名证书】

https服务默认端口443。

 复制代码
const https = require("https");
const url = require("url");
const fs = require("fs");
var options = {
  key: fs.readFileSync("../privatekey.pem"),
  cert: fs.readFileSync("../certificate.pem"),
  passphrase: "123456", //你的密码
};
const server = https.createServer(options, function (req, res) {
  var pathname = url.parse(req.url).pathname;
  console.log("pathname:" + pathname);
  res.writeHead(200, { "Content-Type": "text/plain" });
  res.end("hello-server");
});
server.listen(443, () => {
  console.log("服务器监听localhost:443");
});

https客户端

 复制代码
var options={
    hostname:"localhost",
    port:443,
    path:"/info?abc=123&name=China",
    method:"GET"
};
options.agent = new https.Agent(options);
//构造https请求（客户端）【自签名证书非法，应该使用正式正式】
var req=https.request(options,function(res)
{
    console.log("STATUS:"+res.statusCode);
    console.log("HEADERS:%j",res.headers);
    res.setEncoding("utf8");
    res.on("data",function(chunk)
    {
        console.log("response:"+chunk);
    });
});
req.end();//发送请求

通过浏览器去验证一下你的https服务器，https://localhost:443/find?name=123

浏览器默认会阻止打开未认证的https页面，可以输入thisisunsafe
