I'm using transloadit and sending files with xhr using valumns file uploader.
Files are sent to the server without errors (i checked size and content of request.body.read) but once I do:
response = assembly.submit! (request.body)
An empty file is sent (I checked many times in the assemblies history page).
Thanks for you help.
Call request.body.rewind before using request.body.

So I have been getting the infamous 404.3 error when trying to use AXAJ to access a .json file launching the site (or more of a test app hehe) through WebMatrix on localhost.
Yes, I am aware of the IIS configuration. I am on Windows 8.1(x64), so I had to even turn on MIME types functionality separately. I configured a MIME type for .json with application/javascript. Then I went and added a handler to *.json, pointed it to C:\WINDOWS\system32\inetsrv\asp.dll. I set the verbs to GET and POST (those are what I use in my ajax function). I also tried unchecking the "Invoke the handler only if request is mapped to..." to no avail.
I am using one function to send data to PHP file which writes it to the JSON file and then another to fetch data from the JSON file directly. Writing through PHP works. Fetching doesn't. I am completely at a loss, does anyone have any ideas? The code I am using to fetch the data is your bog-standard ajax:
function getDate(path, callback) {
var httpRequest = new XMLHttpRequest();
httpRequest.onreadystatechange = function() {
if (httpRequest.readyState === 4) {
if (httpRequest.status === 200) {
var data = JSON.parse(httpRequest.responseText);
if (callback) callback(data);
}
}
};
httpRequest.open('GET', path);
httpRequest.send();
}
When I host this on my server space, it works totally fine. But I want to get it to work locally for testing purposes as well.
If writing to the file works but fetching doesn't work. Then you should check for the link of the file.
The error 404 as the name refers to, is an error for the file name. There isn't any other sort of error, even the Ajax request is working fine and giving the error 404 (file not found). So the only thing that you can do is, to make sure that while fetching the data, you use the correct link.
Here can be a help, when you send the Request through Ajax, there is a Network tab in your Browser's console. Open it, and look for the request. It would in red color denoting an error and click it. You'll see that the link you're providing isn't valid.
Look for the errors in the File Link then and update it.
The lengths I go to, to clean up my profile...
When you require a JSON format, or any file for that matter you have to specify in your request what data type you need, IIS will not make any assumptions. So
xhr.setRequestProperty('Content-Type', 'application/json');
is something one must not forget. I set also the X-Requested-With header. Note that to reproduce this issue I used IIS that is installed on Windows 10 Pro, so not exactly the same system (3 years later - holy crap!).
Manual Uploader Working Fine with All Browser expect IE 10, i am not getting correct Response From the Server it is Showing on onComplete "No Valid message Received from Loaded iframe For i frame Name 1_97604 cec......".
File are uploading into the cloudbees server but not getting correct Response From the server.
In case of Other browser i am getting Response.success = true, but For IE 10 its undefined, how to handle this error. Please help me Out for this.

You aren't using IE10 if that is the message you are seeing. Most likely, you are using IE9 or older. The message you are seeing is logged by the form uploader, which is never used if you are uploading via IE10. Perhaps you are running IE10 in IE9 or IE8 mode. Either way, the message indicates that you are working in a cross-origin environment (you have set the cors.expected option to true) but are not returning the proper response from your server. Note that older browsers, such as IE9 and older, utilize form submits, targeting an iframe, to upload files. In order to access the contents of that cross-origin iframe, the iframe needs to post a message containing the server response to Fine Uploader's window. This is all very easy to do, all you need to do is return a text/html response from your server that looks something like this:
"{\"success\": true, \"uuid\": \"9da17ad5-ad6a-40cd-81b5-226e837db45b\"}<script src=\"http://<YOUR_SERVER_DOMAIN>/iframe.xss.response-<VERSION>.js</script>.js\"></script>"
The javascript file mentioned in the script tag is provided in the Fine Uploader released zip file. It does all of the work for you. You must return a JSON response before the script tag, as illustrated above, and the response must include the UUID of the associated file.
You should read about cross-origin support either in the associated blog post.
My server returns status code for upload (201) with empty body. I can upload data to server but then onComplete callback is fired i get
Error when attempting to parse xhr response text (SyntaxError: Unexpected end of input)
FineUploader expects JSON response which i did not provide, is there any way (except manualy modify FinneUploader JS file) to tell FineUploader not to attempt parse response and just check for valid status?
No. You will find that relying on status codes will cause you problems in IE9 and older, since a form inside a hidden iframe is submitted for each file in those browsers, and there is no way, via javascript, to determine the response code for such a request.
For each time $this->session->set_userdata() or $this->session->set_flashdata() is used in my controller, another identical "Set-Cookie: ci_session=..." is added to the http header the server sends.
Multiple Set-Cookie fields, with the same cookie name, in the http header is not okay according to rfc6265.
So is there a way to use codeigniter sessions without it creating multiple identical "set-cookie:"s?
(I've used curl to verify the http header)
check https://github.com/EllisLab/CodeIgniter/pull/1780
By default when using the cookie session handler (encrypted or unencrypted), CI sends the entire "Set-Cookie" header each time a new value is written to the session. This results in multiple headers being sent to the client.
This is a problem because if too many values are written to the session, the HTTP headers can grow quite large, and some web servers will reject the response. (see http://wiki.nginx.org/HttpProxyModule#proxy_buffer_size)
The solution is to only run 'sess_save()' one time right after all other headers are sent before outputting the page contents.
I believe you can pass an array to $this->session->set_userdata(); I haven't tested this code so it is merely a suggestion to try something along these lines:
$data = array(
'whatever' => 'somevalue',
'youget' => 'theidea'
);
$this->session->set_userdata($data);
NB: When I say I haven't tested the code.. I have used this code and I know it works, I mean I havent tested if it will reduce the amount of headers sent.
In my case, the error is in the browser (Chrome). It stored 2 cookie and send both to server, this make server create new session all the time.
I fixed it by clear the cookies in browser.
Hope it help someone. :)
I have a file in the website and i m trying to send this file to windows application using the Response.BinaryWrite (getContent)( Where getContent is the byte array having the file which I need to send) vis HTTP post method only. Also I m adding a Header and Content-Type as application/octet-stream in the Response.
Now while reading the (httpWebResponse) response in the stream at client side(windows application) all the things (header + content-type + file + some extra bytes) are getting added. so when I try to read the file in stream it cannot be loaded since the content has chnged
Is there any way to separate the file from rest contents present in the response object..
How sahll I save this file in directory
Use System.Net.WebClient.DownloadData or DownloadFile method instead.
What language / version are you using?
If you are using a reasonably up-to-date version of C# you can use the WebClient class, and its DownloadFile method
