Question

我对节点非常陌生，并且已经查找了如何简单地设置节点服务器。我觉得我已经正确设置了它，但当我去https://localhost:8080/它说'＃34;网站无法到达＆＃34;。没有任何东西是控制台记录。我已经经历了许多类似的问题，但还没有解决方案帮助过我。我运行了npm init和npm install，这是我的代码：

var Express = require('express');
var Https = require('https');
var Fs = require('fs');

var app = Express();
var port = process.env.EXPRESS_PORT || 8080;
var options = {
  key: fs.readFileSync('key.pem'),
  cert: fs.readFileSync('cert.pem')
};
console.log("helloo?");

express.createServer(options, function (req, res) {
  console.log("hi")
  res.writeHead(200);
  res.end("hello world\n");
}).listen(8080);

Answer 1

代码中存在许多拼写错误，为了使其正常工作，我已经完成了更改。

要创建https服务器，您必须使用内置的node.js https模块并通过传递证书创建https服务器，如下所示

GoTo - https://localhost:8080/

回应：

{ message: "this is served in https" }

var express = require('express');
var https = require('https');
var fs = require('fs');

var app = express();
var port = process.env.EXPRESS_PORT || 8080;
var options = {
  key: fs.readFileSync('key.pem'),
  cert: fs.readFileSync('cert.pem')
}
console.log("helloo?");

app.get('/', function(req, res) {
    res.json({
        message: 'this is served in https'
    })
})

var secure = https.createServer(options, app); // for express

secure.listen(port, function() {
    console.log('localhost started on', port)
})

// for just node server request listener

/* https.createServer(options, (req, res) => {
  res.writeHead(200);
  res.end('hello world\n');
}).listen(port); */

我为你写了一个基本代码。我认为这对你和你的答案都有用。试试这个。其他的事情是，如果你使用快递，那么无需导入http模块连接到服务器。我已经评论了一些代码，逐一尝试。

＆＃13;

var express = require('express');
var app = express();
const fs = require('fs');
//const  http = require('http');

app.set('port',process.env.PORT || 3000);

app.get('/',function(req, res){
  res.send('Hellow World');
});

const fileName = __dirname + '/test.txt';
fs.readFile(fileName, (err, data) => {
   if (err) {
       console.error(err);
   }console.log('Done!');
   console.log(data.toString());
});

//or
/*
const data = fs.readFileSync(fileName);
console.log(data.toString());
*/

//below code will print whatever characters inside test.txt into test-copy.txt file
/*
const filename = __dirname + '/test.txt';
const outFileName = __dirname + '/test-copy.txt';

const readStream = fs.createReadStream(filename);
const writeStream = fs.createWriteStream(outFileName);

readStream.pipe(writeStream);

readStream.on('data', data => {
  console.log(data.toString());
});
*/
app.listen(app.get('port'), function(){
  console.log('Server listenning at port 3000');
});

首先，您必须创建test.txt文件并在其中写入内容。如果您尝试注释代码，请创建tezt-copy.txt文件。
