七牛上传失败

我用jquery.uploadfile做上传实例，代码如下：

<code class="lang-javascript">var uploadObj = $("#fileuploader").uploadFile({
url:"http://up.qiniu.com/",
multiple:true,
autoSubmit:false,
fileName:"myfile",
formData: {"key":"<key>","token":"<mytoken>"},
maxFileCount:1,
showStatusAfterSuccess:false,
dragDropStr: "<span><b>拖放文件</b></span>",
abortStr:"放弃",
cancelStr:"终止",
doneStr:"OK",
multiDragErrorStr: "几个拖放文件是不允许的。",
extErrorStr:"不允许的扩展名",
sizeErrorStr:"不允许的大小",
uploadErrorStr:"禁止上传"
});
$("#startUpload").click(function()
{
    uploadObj.startUpload();
});
</mytoken></key></code>

服务端错误是

<code class="lang-javascript">{"error":"file is not specified in multipart"}
</code>

这个问题类似吗？应该是文件类型问题吧

我也遇到了这个问题，
如果图中标红的值不为file，就会报这个错误。首先，你要将input 的 name设为file，如果你用的是pluploader，可以在参数里面设置这个值，仔细阅读api
