nodejs中multiparty實作檔案上傳的程式碼範例

var multiparty = require('multiparty');
function fileUpload(req,res)
    {
        //生成multiparty对象，并配置上传目标路径
        var form = new multiparty.Form({uploadDir: '../static/images/'});
        //上传完成后处理
        form.parse(req, function(err, fields, files) {
        var filesTmp = JSON.stringify(files,null,2);
        if(err){
            } else {
            var inputFile = files.file[0];
            var uploadedPath = inputFile.path;
            var dstPath = '../static/images/' + inputFile.originalFilename;
             //重命名为真实文件名
            fs.rename(uploadedPath, dstPath, function(err) {
            if(err){
                    console.log('rename error: ' + err);
                    } else {
                    console.log('rename ok');
                    }
                });
            }
            res.send({"fileName":inputFile.originalFilename});
        });
    }
 route.post('/fileUpload',(req,res)=>{
        fileUpload(req,res);
    });
