In my app i need to upload a audio file and xml file to server. I successfully post audio file. But i don’t know how to send two files in parallel. Anyone please help me.
NSString *soundFilePath = [[self GetDocumentDirectory]
stringByAppendingPathComponent:audioDet.audioName];
NSMutableData *file1Data = [[NSMutableData alloc] initWithContentsOfFile:soundFilePath];
//uploads/
NSString *urlString = #"http://192.168.1.99/projects/fileUpload/upload.php";
NSString *filename = audioDet.audioName;
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"];
[request setValue:#"Crystal" forHTTPHeaderField:#"ClientApp"];
[request setValue:#"1.0" forHTTPHeaderField:#"ClientVersion"];
[request setValue:#"617272656E64616C65445652" forHTTPHeaderField:#"ClientCredential"];
[request setValue:audioDet.audioName forHTTPHeaderField:#"Target-file-name"];
[request setValue:[NSString stringWithFormat:#"%#",audioDet.audioFileSize] forHTTPHeaderField:#"Target-file-length"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// NSString * value1 = [NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; name=\"%#\"\r\n", filename];
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"%#\"\r\n", filename ] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:file1Data]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
Thanks,

Store the multiple files in an array and iterate the same using for loop to send multiple files in the server.

i want to upload a file, an image, to a website. I have read the SimpleFTPSample from Apple. It´s work with the TestPhotos but it´s too complicated. Can someone post a simple Code, where i can put my URL in it? I have used BlackRaccoon and ASIHTTPRequest but it doesn´t work.
Thanks
What worked easiest for me was to write a small php script and upload the file to that. The php isn't that sophisticated but it works
be sure to replace the urls with your site name
upload.php
<?php
$uploaddir = 'Images/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
echo "transfer successful at: http://YOURWEBSITE.COM/{$uploaddir}/{$file}";
}
?>

NSLog(#"upload url%#", urlString);

I am writing an HTTP Post request, but for some reason the parameters are not being added correctly, and I can't for the life of me figure out what I'm doing wrong. Here's what I have:
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:#"text; boundary=%#", boundary];
[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// Dictionary that holds post parameters.
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];
[_params setObject:subject forKey:#"subject"];
[_params setObject:message forKey:#"message"];
[_params setObject:[[UIDevice currentDevice] systemName] forKey:#"device"];
// add params
for (NSString *param in _params) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"%#\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}
// the server url
NSURL* requestURL = [NSURL URLWithString:CIVCManifest.contactFeed];
[body appendData:[[NSString stringWithFormat:#"--%#--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// set the content-length
NSString *postLength = [NSString stringWithFormat:#"%d", [body length]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
// set URL
[request setURL:requestURL];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
The request is getting through, however all the parameters are not being added properly. I had a Post script working that would upload a photo, and I copied and pasted most of it over to this one, but somehow this one is not working. Hopefully it's just a simple error I'm missing.
Try this
NSString *Post = [[NSString alloc] initWithFormat:#"Post Parameters"];
NSURL *Url = [NSURL URLWithString:#"Url"];
NSData *PostData = [Post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [PostData length]];
NSMutableURLRequest *Request = [[NSMutableURLRequest alloc] init];
[Request setURL:Url];
[Request setHTTPMethod:#"POST"];
[Request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[Request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[Request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[Request setHTTPBody:PostData];
I need to implement a subclass of NSOperation which does a file upload to a HTTP server and with an option that the user can cancel the file upload during operation.
Here is the code at the moment:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:filename];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:20];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"------WebKitFormBoundary4QuqLuM1cE5lMwCy";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", boundary];
[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
NSString *FileParamConstant = #"uploadFile";
NSData *imageData = [[NSData alloc] initWithContentsOfFile:imagePath];
NSMutableDictionary *parameters = [[NSMutableDictionary alloc] initWithCapacity:11];
[parameters setValue:#"Value" forKey:#"Server_required_param"];
NSString *urlString = #"http://www.omeuendereco/uploadFile.php";
for (NSString *param in parameters) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"%#\"\r\n", FileParamConstant, filename] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: image/jpeg\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imageData];
[body appendData:[[NSString stringWithFormat:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:#"--%#--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
[request setURL:[NSURL URLWithString:urlString]];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request
delegate:up
startImmediately:YES];
[connection start];
the problem is that i have to implement a NSOperationqueue in this code and i dont know how.
Then with the subclass of NSOperation i will be able to cancel the upload operation.
What the hell is your problem ? If you don't know how to make a subclass - learn Objective-C.
If I don't understand you (and there's some sophiscated problem, but I don't think so), you've got two solutions.
CREATE THAT SUBCLASS and then make an instance of NSOperationQueue, add an instance of that subclass to the queue.
Use AFNetworking or MKNetworkKit(MKNetworkKit uses NSOperation and NSOperationQueue)
I've been trying to get file upload working with Box for the past few days. I know I'm doing something wrong, but just can't see what it is.
I've reduced my code down as much as I possibly can, to just this:
// Configure the request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"https://api.box.com/2.0/files/data"]];
[request setHTTPMethod:#"POST"];
[request setValue:boxAuthString forHTTPHeaderField:#"Authorization"];
// Setu up the request
NSString *boundary = [NSString stringWithString:#"--PLEASEHELPMEGETTHISWORKING"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#\r\n",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
// Add the info and data for the file.
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Disposition:form-data;name=\"filename\";filename=\"testfile.txt\"\r\n"]
dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type:text/plain\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Hello"] dataUsingEncoding:NSUTF8StringEncoding]];
// Add the info and data for the target folder.
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Disposition:form-data;name=\"folder_id\"\r\n\r\n"]
dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"0"] dataUsingEncoding:NSASCIIStringEncoding]];
// Close the body and set to the request
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n", boundary] dataUsingEncoding: NSUTF8StringEncoding]];
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"%#", returnString);
But, I still get a return of:
{"type":"error","status":404,"code":"not_found","help_url":"http://developers.box.com/docs/#errors","message":"Not Found","request_id":"10130600215xxxxxxxxxxx"}
Please can someone help point me in the right direction, as when I use POSTMAN or cURL, I can get it to work - so it is obviously an issue with my code. I suspect it is something to do with the 'folder_id', but can't seem to diagnose the actual cause.
Fixed it. The problem was in my 'boundary' construction code. I'd got:
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#\r\n",boundary];
And should have had:
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
Spot the incorrect termination '\r\n'. Oh well. Only wasted about 4 hours on this. :-)

One solution to see what is wrong:
make a new project, using ASIHttpRequest
Get a web debugging proxy like Charles
Turn on Charles (or whatever), do a multi-file upload that succeeds.
Record data from HTTP traffic to server.
Now run your own code. Record that traffic. What is different from
your traffic to the working traffic? Makes yours IDENTICAL in all
respects, and how can it not work?
You can also replace step (1) with a curl command line that uploads multiple files to a server and record that traffic, but I'm not versed enough in curl to say off the top of my head what that command would look like.
- (NSString*) nameValString: (NSDictionary*) dict {//example CHLOVA_FORM_BOUNDARY is #"aaa"
