Question

Rather than using a Handler(.ashx), is it possible to use a web service(.asmx) to upload?

Any suggestions on how to use a jQuery upload to get the input stream?

VB. 希望网络编码或实例。

Answer 1

Yes it is possible , you can pass the File to the service(.asmx) , and get Json back by specifing the response type. better soultion if you want a simple uploader with drag and drop functionality would be Ajax uploader - valums

_uploader = new qq.FileUploader({
                element: document.getElementById(_Uploaddiv),
                onComplete: function (id, fileName, responseJSON) {  },
                action:  /Uploader.asmx/functionName ,
                params: {
                    startRowIndex:_startRowIndex,
                    pageSize:_pageSize
                }

    xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest");
    xhr.setRequestHeader("Accept", "application/json, text/javascript, */*; q=0.01");

set the XMLHttpRequest() headers to Accept json

VB 代码

<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json)> _

Jquery has a Forms plugin which can be used for this purpose. The good thing about it, it supports file upload using AJAX as well.You can locate it here http://plugins.jquery.com/project/form. We are using it with MVC 3.
