I have the following code which uploads an image to a web site.
[request setURL:nsurl];
[request setHTTPMethod:#"POST"];
NSString *boundary = [NSString stringWithString:#"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
/*
now lets create the body of the post
*/
NSMutableData *body = [NSMutableData data];
//parameter1
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"guid\"\r\n\r\n%#", [Settings sharedInstance].uploadID] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//Image
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"filMyFile\"; filename=\"%#\"\r\n", fileName] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: image/png\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:dataObj]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
All is well when running over HTTP, but when I switch to HTTPS it fails with
Error: Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo=0x1c7f70 {NSErrorFailingURLStringKey=https:.......
The server it is communicating with is MS Server 2008 R2.
Any ideas would be appreciated.

I currently upload images in the background to a server like this (the names get changed at the server to something better).
buildURL = [buildURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSData *imageData = UIImageJPEGRepresentation(imageToUpload, 1.0); //change Image to NSData
if (imageData != nil)
{
NSString *filenames = [NSString stringWithFormat:#"imagename"]; //set name here
NSLog(#"%#", filenames);
NSString *urlString = buildURL;
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[filenames dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Disposition: form-data; name=\"userfile\"; filename=\".jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// now lets make the connection to the web
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError)
{
NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"Returned From Image Upload : %#",returnString);
}];
}
This works fine, I can see the images finish in the background no problem. The thing is I want to change this to use NSURLSession and the delegate didSendBodyData so that I can monitor the upload.
I have found a load of information about the download but none really about upload. I have tried to do this with the request BUT the completion block NEVER happens.. I have also tried using uploadTaskWithStreamedRequest but I can not get the delegate to happen...
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration delegate:self delegateQueue:nil];
NSURLSessionDataTask *uploadTask = [session uploadTaskWithRequest:request fromData:imageData completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
NSLog(#"Image Uploaded ------------");
}];
[uploadTask resume];
I also found this StackOverflow 19985353 which seems to highlight some problems but I could really do with some example code. The image is picked from imagePicker if that helps.
I also tried both the answers here StackOverflow 19099448 but neither of them worked, again the block never executed. Is there something fundamental I am doing wrong with NSURLSession, a framework maybe! I also note I have no idea about the HTTP body which I have tried to play with but no luck.
Okay I did not realise that Session only works in iOS7 and above. To this end I have done a test and if iOS6 then I use NSURLConnection. The problem is I cannot get progress status from this (with the session I have an upload bar).
If anyone has any ideas about an upload progress bar using NSURLConnection then I would love to hear about it.
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:_urlToUpload];// create request

NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request fromFile:file completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { }

I am making an application which has the option to choose multiple photos, those photos are then saved in an array, as I can do to send that photo array to the server...
I tried but I'm not able to get.. I hope you can help me with this..
This is my code:
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{

no se si estare bien lo que estoy haciendo..alguna idea por favor de como lo pueda hacer..me esta dando muchos dolores de cabeza..esto es lo que me muestra cuando ejecuto :

Very first question here...
I'm desperately trying to upload a photo to Facebook from my Mac OS App (cocoa), using an HTTP POST request.
Using the "https://graph.facebook.com/me/photos?access_token=....." followed by "source=MyURLOnline.jpg", it works great, but I need to upload the DATA, not a link of an image already on the Web...
So I'm switching "feed" to "photos", and the URL by the RAW data of my NSImage (and maybe the "source=" to "image=" ?).
But : I set the header of my request to "multipart/form-data, boundary=%AaB03x" and add some "\r\n" and "Content-Type: image/jpeg\r\n\r\n" etc to the body, but the only thing I get is the error "(#324) Requires upload file"...
I have a few years of experience on Cocoa but don't know anything about HTTP request, and especially what is the Graph API expecting, so I've read all Facebook help I found, would have loved to find an example as I'm sure I make several mistakes, but I'm wondering if it is just possible at all.
ANY help appreciated !
UPDATE:
Thank you very much Anvesh.
If you know that I should POST a JSON then I spent my day trying to figure out how to do that, but no success yet.
Here is my code, if I POST a "source=URLOnline.jpg" to the "feed" (and remove the HTTPHeader and the Body), my image shows on my wall. With my image data to the "photos", the only hint I receive is the #324 error...
Wondering where I can find out what I should exactly write in the HTTPBody.
// Convert NSImage to data

Thank you Anvesh, with your help and a Cocoa post about HTTP POST, I finally managed to create my NSURLRequest to upload my NSImage to Facebook.
I hope it will save a lot of trouble to people connecting their Mac App to Facebook, as there is no SDK.

I’ve been trying to follow some examples for uploading data to a website. I want to save the message as a .txt file. Any ideas what to do here?

Here is the upload.php file. I’m assuming the issue is with this but not sure. I don’t know where the filename gets set in the example above. This code was used from somewhere else.
<?php
$uploaddir = './'; //Uploading to same directory as PHP file
$file = basename($_FILES['userfile']['name']);
$uploadFile = $file;
$randomNumber = rand(0, 99999);
$newName = $uploadDir . $randomNumber . $uploadFile;
if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
echo "Temp file uploaded.";
} else {
echo "Temp file not uploaded.";
}
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newName)) {
}
?>
