跟着教程一步一步来的，链接：http://www.nodebeginner.org/index-zh-cn.html 但是文件上传那部分总是报错。

代码如下：

function upload(response, request) {  console.log("Request handler 'upload' was called.");  var form = new formidable.IncomingForm();  console.log("about to parse");  form.parse(request, function(error, fields, files) {    console.log("parsing done");    fs.renameSync(files.upload.path, "/tmp/test.png");    response.writeHead(200, {"Content-Type": "text/html"});    response.write("received image:<br/>");    response.write("<img src='/show' />");    response.end();  });}

报错：

估计又是权限的问题吧，把上述代码改为如下即可正确运行。

function upload(response, request) {  console.log("Request handler 'upload' was called.");  var form = new formidable.IncomingForm();  console.log("about to parse");  form.uploadDir = "./tmp"; // add this one  form.parse(request, function(error, fields, files) {    console.log("parsing done");    console.log(files.upload.path);    fs.renameSync(files.upload.path, "./tmp/1.jpg"); //also,change to ./tmp/1.jpg    response.writeHead(200, {"Content-Type": "text/html"});    response.write("received image:<br/>");    response.write("<img src='/show' />");    response.end();  });}
