node 学习笔记

var form = new formidable.IncomingForm();
     form.parse(request, function(error, fields, files) {
        fs.renameSync(files.upload.path, "./tmp/test.png");//报错
        response.writeHead(200, {'content-Type':'text/html'});
        response.write('received image:<br/>');
        response.write('<img src="/show" />');
        response.end();
     });

报错：
Error: EXDEV, cross-device link not permitted

解决方案:

var form = new formidable.IncomingForm();
     form.uploadDir='tmp';//加入这行代码

参考： 跨磁盘分区移动或操作文件会有权限问题
