问题描述

在运行Express.js(3.8.6)的简单节点服务器上.我正在尝试使用sendFile将简单的HTML文件发送到客户端.

On a simple node server running Express.js (3.8.6). I am attempting to use sendFile to send a simple HTML file to the client.

从读取的文件来看，该路径是正确的.
浏览器上的缓存已禁用.
显示的代码是server.js文件，直接从节点运行

我想念什么?

代码

//server.js

var http = require("http");
var express = require("express");
var app = express();
var server = http.createServer(app);
var path = require('path');

//Server views folder as a static in case that's required for sendFile(??)
app.use('/views', express.static('views'));
var myPath = path.resolve("./views/lobbyView.html");

// File Testing
//--------------------------
//This works fine and dumps the file to my console window
var fs = require('fs');
fs.readFile(myPath, 'utf8', function (err,data) {
  console.log (err ? err : data);
});

// Send File Testing
//--------------------------
//This writes nothing to the client and throws the ECONNABORTED error
app.get('/', function(req, res){
  res.sendFile(myPath, null, function(err){
    console.log(err);
  });
  res.end();
});

推荐答案

您正在过早调用res.end().请记住，Node.js是异步的，因此您实际上正在做的是在sendFile完成之前将其取消.将其更改为:

You're prematurely calling res.end(). Remember, that Node.js is asynchronous, thus what you're actually doing is cancelling your sendFile before it completes. Change it to :

app.get('/', function(req, res){
  res.sendFile(myPath, null, function(err){
    console.log(err);
    res.end();
  });
});
