我有一个驻留在public/images/logo.gif
的徽标。这是我的nodejs代码。
http.createServer(function(req, res){
res.writeHead(200, {'Content-Type': 'text/plain' });
res.end('Hello World \n');
}).listen(8080, '127.0.0.1');
它可以工作,但当我请求localhost:8080/logo.gif
时,我显然得不到徽标。
我需要做哪些更改才能为镜像服务。

var http = require('http');
var fs = require('fs');
http.createServer(function(req, res) {
res.writeHead(200,{'content-type':'image/jpg'});
fs.createReadStream('./image/demo.jpg').pipe(res);
}).listen(3000);
console.log('server running at 3000');

太晚了,但帮助了别人,我在用node version v7.9.0
和express version 4.15.0
如果你的目录结构是这样的:
your-project
uploads
package.json
server.js
server.js代码:
var express = require('express');
var app = express();
app.use(express.static(__dirname + '/uploads'));// you can access image
//using this url: http://localhost:7000/abc.jpg
//make sure `abc.jpg` is present in `uploads` dir.
//Or you can change the directory for hiding real directory name:
`app.use('/images', express.static(__dirname+'/uploads/'));// you can access image using this url: http://localhost:7000/images/abc.jpg
app.listen(7000);

请求的Vanilla节点版本:
var http = require('http');
var url = require('url');
var path = require('path');
var fs = require('fs');
http.createServer(function(req, res) {
// parse url
var request = url.parse(req.url, true);
var action = request.pathname;
// disallow non get requests
if (req.method !== 'GET') {
res.writeHead(405, {'Content-Type': 'text/plain' });
res.end('405 Method Not Allowed');
return;
}
// routes
if (action === '/') {
res.writeHead(200, {'Content-Type': 'text/plain' });
res.end('Hello World \n');
return;
}
// static (note not safe, use a module for anything serious)
var filePath = path.join(__dirname, action).split('%20').join(' ');
fs.exists(filePath, function (exists) {
if (!exists) {
// 404 missing files
res.writeHead(404, {'Content-Type': 'text/plain' });
res.end('404 Not Found');
return;
}
// set the content type
var ext = path.extname(action);
var contentType = 'text/plain';
if (ext === '.gif') {
contentType = 'image/gif'
}
res.writeHead(200, {'Content-Type': contentType });
// stream the file
fs.createReadStream(filePath, 'utf-8').pipe(res);
});
}).listen(8080, '127.0.0.1');
