[英]Cloud9 - Node.js fs can't open an html file
I do experiments with node.js and socket.io and it works fine locally. 我使用node.js和socket.io进行了实验,并且在本地工作良好。 I can read an html file and manage an interactive button for several users. 我可以阅读html文件并为多个用户管理一个交互式按钮。
So i uploaded it on Cloud9 but i have an error ENOENT trying to find the html file . 所以我将其上传到Cloud9上,但是尝试查找html文件时出现错误提示 。 It's in root (like in local) and the line is fs.readFile('ex.html' etc... 它位于根目录(如本地),其行是fs.readFile('ex.html'等)。
Here is the code of a test to open an html file and i have the enoent error on the console : 这是打开html文件的测试代码,控制台上出现enoent错误 :
var http = require('http');
var fs = require('fs');
http.createServer(function(request, response) {
response.writeHead(200, {
'Content-Type': 'text/html'
});
fs.readFile('ex.html', function(err, data){
if(err) throw err;
response.end(data);
});
}).listen(process.env.PORT, process.env.IP);
Here is another program (full) that displays a blank page ... 这是另一个程序(完整) ,显示空白页 ...
server : 服务器:
var http = require('http');
var fs = require('fs');
// Creation du serveur
var app = http.createServer(function (req, res) {
// On lit notre fichier app.html
fs.readFile('app.html', 'utf-8', function(error, content) {
res.writeHead(200, {'Content-Type' : 'text/html'});
res.end(content);
});
});
var io = require("socket.io");
io = io.listen(app);
io.sockets.on('connection', function (socket) {
socket.on('joue', function () {
socket.broadcast.emit('joue2');
}); // joue
}); // connection
app.listen(process.env.PORT, process.env.IP);
client (app.html) : 客户(app.html):
<html><head> <title>Hello</title></head><body>
<button id="button">clic</button>
<div id="render">a</div>
<script type="text/javascript" src="/socket.io/socket.io.js"></script>
<script type="text/javascript">
var socket = io.connect();
var button = document.getElementById('button');
var render = document.getElementById('render');
button.addEventListener("click", clique, false);
function clique() {
socket.emit('joue');
}
socket.on('joue2', function () {
if (render.innerHTML == 'a') {
render.innerHTML = 'clic multi';
} else {
render.innerHTML = 'a';
}
});
</script></body></html>
I have installed socket.io on the server and all files are in the root of the folder node.js. 我已经在服务器上安装了socket.io,所有文件都位于node.js文件夹的根目录中。 I already asked to Cloud9 but they said it works for them... Sorry for my english and if im a beginner. 我已经问过Cloud9了,但是他们说这对他们有用。很抱歉我的英语,如果我是初学者。
Thank you for your help :) 谢谢您的帮助 :)
I guess your ex.html
file is in node.js directory. 我猜你的ex.html
文件在node.js目录中。
Try fs.readFile('node.js/ex.html', ...
尝试fs.readFile('node.js/ex.html', ...
