copied!<p>I'm trying to upload some text content via ajax, that will be parsed later. That is my Javascript code: </p> <pre><code> $("#fuFile").change(function () { var fileInput = document.getElementById("fuFile"); var file = fileInput.files[0]; var formdata = new FormData(); formdata.append('file', file); var xhr = new XMLHttpRequest(); xhr.open("POST", 'testhandler.ashx', true); xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest"); xhr.setRequestHeader("X-File-Name", file.name); xhr.setRequestHeader("Content-Type", "application/octet-stream"); xhr.send(formdata); }); </code></pre> <p>Where <code>fuFile</code> is my file input, and <code>testhandler.ashx</code> is the server handler that gets the uploaded file. (I actually use another handler to parse the file content.) </p> <p>BUT when I try to do this: </p> <pre><code>HttpFileCollection fc = context.Request.Files; </code></pre> <p>It returned no files. But Works in IE for some reason.</p> <p>But when I try to get the input stream:</p> <pre><code> StreamReader stream = new StreamReader(context.Request.InputStream); string text = stream.ReadToEnd(); </code></pre> <p>The <code>text</code> variable become (Http Headers) + File Content.</p> <pre><code>------WebKitFormBoundaryx16Mw7tnG6JeflIB\r\nContent-Disposition: form-data;name=\"file\"; filename=\"teste export.CSV\"\r\nContent-Type: application/vnd.ms-excel(..file content..) </code></pre> <p>That's OK, but I've used this plugin: <a href="http://valums.com/ajax-upload/" rel="nofollow">http://valums.com/ajax-upload/</a></p> <p>And the plugin returned me only the file content, in witch I could get the content via InputStream, I didn't received any HTTP header.</p> <p>That's PERFECT, but I want to make a Upload script without using plugins. Just upload and parse, returning some results. Simple and fast</p> <p>So, My question is: <strong>How to get the file content, uploaded by Ajax XHR, getting ONLY the file content, in any browser?</strong></p>

Querying!
