node多种方法实现文件下载 - CNode技术社区

exports.download = function(req,res){
 var downloadPath = Config.outName;
	console.log('downloadPath='+downloadPath);
	res.download(downloadPath); //express自带下载
 /*path.exists(downloadPath, function(exists) {
 console.log("exists: ", exists);
 if (exists) {
 var fileStream = fs.createReadStream(downloadPath);
 res.writeHead(200, {"Content-Type":"application/octet-stream"});
 fileStream.pipe(res);
 console.log('fileStream pipe');
 fileStream.on("end", function() {
 res.end();
 })
 }
 });*/
	/*var filename = path.basename(downloadPath);
 	var mimetype = mime.lookup(downloadPath); //匹配文件格式
	res.setHeader('Content-disposition', 'attachment; filename=' + filename);
 	res.setHeader('Content-type', mimetype);
 	var filestream = fs.createReadStream(downloadPath);
 	filestream.on('data', function(chunk) {
 	res.write(chunk);
 	});
 	filestream.on('end', function() {
 	res.end();
 	});*/
};
