POError #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error
text
Body
copied!<p>I have a standard AIR script compiled on Flash or Flash Builder 4.5 designed to upload a file to a php server-side code. The code starts by writing the file to the users desktop, before completing the request.</p> <pre><code>import flash.net.*; import flash.filesystem.* //create the file var file:File = File.desktopDirectory; file = file.resolvePath("test.txt"); var fs:FileStream = new FileStream(); fs.open(file, FileMode.WRITE); //write "test" to txt file fs.writeUTFBytes("test"); fs.close(); //start request var req:URLRequest = new URLRequest(); req.method = "POST"; req.url = //php file var vars:URLVariables = new URLVariables(); vars.a = 1; vars.b = 2; vars.c = 3 req.data = vars; file.upload(req, "txt_file"); </code></pre> <p>Now, when I upload to a php file on my own Apache test server on localhost (XAMPP), the file upload goes through without any errors. However, when I try to upload to my actual server, I get an I/O error: </p> <blockquote> <p>Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.</p> </blockquote> <p>I have checked my max_file_size set at 2MB so that is not the issue. The URL is also correct. Looking at other sources (e.g. <a href="http://www.judahfrangipane.com/blog/2007/01/01/error-2044-unhandled-ioerrorevent-texterror-2038-file-io-error/" rel="nofollow">http://www.judahfrangipane.com/blog/2007/01/01/error-2044-unhandled-ioerrorevent-texterror-2038-file-io-error/</a>), some suggest the issue is with Apache ModSecurity, turned off by setting .htaccess for the directory to:</p> <pre><code>SecFilterEngine Off SecFilterScanPOST Off </code></pre> <p>This does not work. In fact, it makes the rest of my code designed to obtain data from the same server obsolete. I also know its not a cross-domain issue. I have also tried setting the php code to return HTTP 200. Still does not work. Some have suggested that these errors are a bit random and the actual file upload has taken place regardless of the error. So the problem could be fixed by just catching the error and ignoring it (<a href="http://dev.nuclearrooster.com/2008/04/05/uploading-with-a-filereference-from-flex-3-on-os-x/" rel="nofollow">http://dev.nuclearrooster.com/2008/04/05/uploading-with-a-filereference-from-flex-3-on-os-x/</a>). This is not an option for me as I need to track the upload progress.</p> <p>What is interesting is that this seems to be a Mac OSX issue as I have the exact script running on a Windows compiler without errors although the only stipulation is that they were made with older version of AIR. So I am not sure whether that is the case here. </p> <p>I have been banging my head against the wall for 3 days. Please help me......</p> <p><strong>UPDATE</strong></p> <p>Just found that my server where the file is uploading to is returning a HTTP 301 response on the file upload request, something which again only happens on OSX on AIR and not on Windows or form data submitted via Firefox.</p>
