uploading HDvideo to the server using ASIFormDataRequest.
but it taking long time to upload.
my code is
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
if (movieUrl != Nil) {
NSData *videoData = [NSData dataWithContentsOfURL:movieUrl];
[request addData:videoData withFileName:[movieUrl lastPathComponent] andContentType:#"audio/mp4" forKey:#"video"];
[request setRequestMethod:#"POST"];
//
[request setTimeOutSeconds:600];
[request setDelegate:self];
//
[request setUploadProgressDelegate:progressView];
[request startSynchronous];
where movieurl is url return from imagepickerdidfinish
movieUrl = (NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];
Well you are doing All of this synchronously which means your interface is blocked and seem unresponsive. I would recommend using asynchronous connection which will be way more responsive, executing on a separate thread and not blocking the main thread. Use:
[request startAsynchronous]

I have a website that i want to log into from my iphone in a iphone app i am making, i followed the documentation on ASIHttpRequests website but all i get from the response string is the html code for the login page , but i get a OK http code, Why is this happening?
Here is my code :
-(IBAction)fetchData:(id)sender
{
NSURL *url = [NSURL URLWithString:#"http://www.rssit.site90.com/login.php"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request shouldPresentCredentialsBeforeChallenge];
[request setRequestMethod:#"POST"];
[request setPostValue:#"" forKey:#"username"];
[request setPostValue:#"" forKey:#"password"];
[request setDelegate:self];
[request startAsynchronous];
//Add finish or failed selector
[request setDidFinishSelector:#selector(requestLoginFinished:)];
[request setDidFailSelector:#selector(requestLoginFailed:)];
}
- (void)requestLoginFinished:(ASIHTTPRequest *)request
{
NSString *yourResponse = [request responseString];
NSLog(#"%#", yourResponse);
}
The form on that page is doing a get, not a post. Your server is probably not expecting POST data, and is looking at query string params instead. Change to
[NSURL URLWithString:#"http://www.rssit.site90.com/login.php?username=YOURUSERNAME&password=YOURPASSWORD"];
and set the requestMethod to GET.
I have changed over to NSURLConnection and NSURLRequest delegates for my db connections etc.
I was using the ASIHTTPRequest libraries to do all this stuff but finally decided to move on due to the lack of support for that 3rd party library.
what I am woundering is how do I send post requests to my db like you do with the ASIFormDataRequest as shown below
//This sets up all other request
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setDelegate:self];
[request setValidatesSecureCertificate:NO];
[request setPostValue:#"ClientDataSet.xml" forKey:#"filename"];
[request startSynchronous];
i.e. how to do send the setPostValues with the NSURLRequest class?
any help would be greatly appreciated
Using NSURLRequest is slightly more difficult than utilizing ASIHTTPRequest. You have to build your own post body.
NSData *postBodyData = [NSData dataWithBytes: [postBodyString UTF8String] length:[postBodyString length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:yourURL];
[request setHTTPMethod: #"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
[request setHTTPBody:postBodyData];
Is it possible to resume canceled download in ASIHTTPRequest? I download file with this code:
NSURL *url = [NSURL URLWithString:urlString];
ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:url];
[request setTemporaryFileDownloadPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.download",fileName]]];
[request setDidFailSelector:#selector(requestDidFailed:)];
[request setDidStartSelector:#selector(requestDidStarted:)];
[request setDidFailSelector:#selector(requestDidFinished:)];
[request setAllowResumeForFileDownloads:YES];
[request setDownloadDestinationPath:path];
[request setShowAccurateProgress:YES];
[request startAsynchronous];
And cancel with this code:
[request cancel];
How to resume this download if it's possible? Or how to pause requests correctly?

i want to upload an
UIImage
to a server.
the problem i dont know how to add it to my post to the server.
until now i sent post with thia:
NSString *reqURL = [NSString stringWithFormat:#"url"];
reqURL = [reqURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:reqURL]];
NSURLResponse *resp = nil;
NSError *err = nil;
NSData *response = [NSURLConnection sendSynchronousRequest: theRequest returningResponse: &resp error: &err];
there is any different way to do for image?
Use ASIHttpRequest
-(void)uploadImage{
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
// Upload a file on disk
[request setFile:#"/Users/ben/Desktop/ben.jpg" withFileName:#"myphoto.jpg" andContentType:#"image/jpeg"
forKey:#"photo"];
// Upload an NSData instance
[request setData:UIImageJPEGRepresentation(myUIImage) withFileName:#"myphoto.jpg" andContentType:#"image/jpeg" forKey:#"photo"];
[request setDelegate:self];
[request setDidFinishSelector:#selector(uploadRequestFinished:)];
[request setDidFailSelector:#selector(uploadRequestFailed:)];
[request startAsynchronous];
}
This answer points to this wrapper framework that should make it easy to do what you want without dealing with HTTP header strings and so on.
Basically, you'll turn your UIImage into an NSData object using a function like UIImagePNGRepresentation() and then upload it over HTTP.
I am using ASIHTTPRequest to fetch some data from a web service.
I am making requests using a loop.
The problem is that it doesn't seem the request is going asynchronously so that my activityindicator is not working .
Is it true that ASIHTTPRequest is not asynchronous .
or should i use the regular nsmutablerequest to perform asynchronous request .
You should put your request in a download queue, i.e.
ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:url];
[request setDelegate:self];
[request setDidFinishSelector:#selector(requestDone:)];
[request setDidFailSelector:#selector(requestWentWrong:)];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[queue addOperation:request];
[request release];
Just
[request startAsynchronous];
runs the request on the UI thread, so you should try it with download queue.
For Sync Synchronous
NSURL *url = [NSURL URLWithString:#"http://allseeing-i.com"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request startSynchronous];
NSError *error = [request error];
if (!error) {
NSString *response = [request responseString];
}
Creating an asynchronous request
- (IBAction)grabURLInBackground:(id)sender
{
NSURL *url = [NSURL URLWithString:#"http://allseeing-i.com"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request startAsynchronous];
}
- (void)requestFinished:(ASIHTTPRequest *)request
{
// Use when fetching text data
NSString *responseString = [request responseString];
// Use when fetching binary data
NSData *responseData = [request responseData];
}
- (void)requestFailed:(ASIHTTPRequest *)request
{
NSError *error = [request error];
}
And there is lot of more options like Queue and many more
