我正在尝试通过Node.js上传和下载图像到服务器,我正在使用以下代码:
var http = require('http'),
path = require('path'),
os = require('os'),
fs= require('fs'),url = require('url');
var Busboy = require('busboy');
http.createServer(function(req, res) {
if (req.method === 'POST') {
var busboy = new Busboy({ headers: req.headers });
busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
var saveTo = ".\\Images\\"+filename;
file.pipe(fs.createWriteStream(saveTo));
});
busboy.on('finish', function() {
res.writeHead(200, { 'Connection': 'close' });
res.end("That's all folks!");
});
return req.pipe(busboy);
}
else{
var request = url.parse(req.url, true);
console.log(request);
var action = request.pathname;
console.log(action);
if (action !== '/') {
var img = fs.readFileSync('.'+action);
res.writeHead(200, {'Content-Type': 'image/gif' });
res.end(img, 'binary');
} else {
res.writeHead(200, {'Content-Type': 'text/plain' });
res.end('Hello World \n');
}
}
res.writeHead(404);
res.end();
}).listen(8082, function() {
console.log('Listening for requests');
});
当我尝试使用HTTP GET从该服务器获取图像,地址为
http://localhost:8082/images/betty.jpg
时,请求被满足并成功接收到图像,但同时还会抛出以下错误: ^
fs.js:438
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);

将因jfriend00提到的原因被严重弃用,并且在fs的后续版本中将无法使用。 - Zachary Dahan
