ASIHTTPRequest time out - iphone

Hello
I am sending some values to the server using ASIHTTPRequest. All works fine until yesterday that the requestFinished didnt work. (when the app send the request on the server an activity indicator and a new view added to the main view and when the request finished is removing the views). I added requestFailed to test if is failed and I get this error:
[3438:207] Error Domain=ASIHTTPRequestErrorDomain Code=2 "The request timed out" UserInfo=0x5ad25c0
Its weird because the same code was working fine yesterday. I am sure that they didnt make any changes on the server's side.
this is the code:
- (IBAction)convert:(id)sender{
//Get the email from the textfield
NSString *email1 = email.text;
//Save the last used email to load it on the next app launch
[[NSUserDefaults standardUserDefaults] setValue:email1 forKey:#"email"];
//Get the current URL from webview
NSString *currentURL= webView.request.URL.relativeString;
lbl.text = currentURL;
//Count the length of Label
int strL= [lbl.text length];
//The url that the requests will be send.
NSURL *url = [NSURL URLWithString:#"the website"];
//Indicator and its view are loading on the screen
[ind startAnimating];
[self.view addSubview:indView];
//ASIHTTPRequests
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
NSString *watch = [lbl.text substringWithRange:NSMakeRange(23,strL-23)];
NSString *link = [NSString stringWithFormat:#"http://youtube.com/%#",watch];
[request setShouldRedirect:YES];
[request setPostValue:watch forKey:#"url"];
[request setPostValue:email1 forKey:#"email"];
[request setPostValue:format forKey:#"format"];
[request setPostValue:quality forKey:#"quality"];
[request setDelegate:self];
[request startAsynchronous];
NSLog(#"%# %# %# %#",watch,email1,format,quality);
click=NO;
}
and this is the requestFinished:
- (void)requestFinished:(ASIFormDataRequest *)request{
NSString *responseString = [request responseString];
NSLog(#"%#",responseString);
NSLog(#"%#",lbl.text);
NSLog(#"requested finished");
[ind stopAnimating];
[indView removeFromSuperview];
[setView removeFromSuperview];
}

Did you try to increase the timeout value on the request? By default it is 10 seconds, you can make it larger by doing this right before the startAsynchronous call:
[request setTimeOutSeconds:60];

how to display progress bar while downloading file from request response in Asihttp

I am downloading video file from response.
i want to display downloading progress bar of HUD-progress.
but how can i do that.
I am sending verify json to server and server verify that send back the video file bytes. i want to display how much percentage of downloading is done by using HUD-progreasse bar.
If i call [request setDidReceiveDataSelector:#selector(request:didReceiveBytes:)]; than it display how much bytes i got but it doesn't store the bytes into cache file ( it doesn't not store file into phone)
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[[NSURL alloc] initWithString:#"http://testing.io/dev.php/video/verifyReceipt"]];
[request setPostValue:resultAsString forKey:#"verify"];// sending json in post
[request setDidReceiveDataSelector:#selector(request:didReceiveBytes:)];
[request setDidFinishSelector:#selector(requestDone:)];
[request setTimeOutSeconds:120];
[request setDelegate:self];
[request setNumberOfTimesToRetryOnTimeout:2];
[request setDownloadProgressDelegate:self];
request.showAccurateProgress = YES;
[request startSynchronous];
}
-(void)request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data
{
[videoData appendData:data];// appending data with global NSmutabledata
NSLog(#"data is %#",data);
}
- (void)requestDone:(ASIHTTPRequest *)request{
//[MBProgressHUD hideHUDForView:self.view animated:YES];
// SAVED Video PATH
// Get the Document directory
NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
// Add your filename to the directory to create your saved video location
NSString* movLocation = [documentDirectory stringByAppendingPathComponent:[fileName stringByAppendingString:#".mov"]];
if(request.responseStatusCode==200)
{
[videoData writeToFile:movLocation atomically:NO];
NSLog(#"in request done sucsessfully downlaod and store in database %d",request.responseStatusCode);
[DBHelper savePurchaseId:fileName];
[self movieReceived];
}
else{
NSLog(#"in request downlaod and store in database failed %#",request.responseHeaders);
}
}
-(void)requestFailed:(ASIHTTPRequest *)request
{
NSLog(#"%#",request.error);
}
fileUrl = string of URL to download a video.
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:[fileUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.outputStream = [NSOutputStream outputStreamToFileAtPath:destPath append:NO];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
{
// Give alert that downloading successful.
NSLog(#"Successfully downloaded file to %#", destPath);
/* To call delegate to response the result. */
[self.target parserDidDownloadItem:destPath];
HUD.detailsLabelText = [NSString stringWithFormat:#"%# %i%%",[JGlobals getLocalvalue:#"Downloading"],100];
[HUD hide:TRUE];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
// Give alert that downloading failed
NSLog(#"Error: %#", error);
/* To call delegate to response the result. */
[self.target parserDidFailToDownloadItem:error];
[HUD hide:TRUE];
}];
[operation setDownloadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite)
{
// Progress
float totalProgress = (totalBytesWritten / (totalBytesExpectedToWrite * 1.0f) * 100);
HUD.detailsLabelText = [NSString stringWithFormat:#"Downloading %i%%", MIN((int)(totalProgress), 99)];
}];
[operation start];
I'm thinking of a method which might not be the right one, but it going to save you from writing a lot of code.
First set a normal UIProgressView instance as the download progress delegate like this
[request setDownloadProgressDelegate:uiprogreeViewInstance];
Now ASIHTTPRequest framework will take care of updating that progressview when the downloading will be taking place. ProgressView has a property named progress, which ranges from 0.0 to 1.0.
Now instantiate MBProgressHUD, add it as your subview where you want. Set the progress value of the MBProgressHUD instance to that of the UIProgressView. Hide the uiprogressview instance.

ASIHTTPRequest multiple downloads control like pause, resume

I am using ASIHTTPRequest to download video file from URL in background.
I am displaying the downloads with progress-bar & percentage and I want user can control the downloads like pause & resume.
Below is the code:
-(void)Initiate_Download:(NSString*)urlStr contentID:(NSString*)cid progressBar:(UIProgressView*)progressBar
{
NSLog(#"Initiate_Download for cid:%#",cid);
urlStr = [urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:urlStr]];
NSString *fileName = [NSString stringWithFormat:#"%#.mp4",cid];
NSString *destinationPath = [[self VideoDownloadFolderPath]stringByAppendingPathComponent:fileName];
[request setDownloadDestinationPath:destinationPath];
[request setTemporaryFileDownloadPath:[NSString stringWithFormat:#"%#-part",destinationPath]];
[request setDelegate:self];
NSDictionary *rqstDict = [NSDictionary dictionaryWithObjectsAndKeys:cid,#"cid",urlStr,#"url", nil];
[request setUserInfo:rqstDict];
[request setAllowResumeForFileDownloads:YES];
[request startAsynchronous];
}
//Delegate
- (void)requestStarted:(ASIHTTPRequest *)request1
{
//some code
}
- (void)request:(ASIHTTPRequest *)request1 didReceiveResponseHeaders:(NSDictionary *)responseHeaders
{
//some code
}
- (void)requestFinished:(ASIHTTPRequest *)request1
{
//some code
}
- (void)requestFailed:(ASIHTTPRequest *)request1
{
//some code
}
You need to save the URL and destination path of the request for each request and to pause the request use code :-
[request Cancel];
and to resume the request you need to create another request with same URL and destination path. For example :-
ASIHTTPRequest *requestToResume = [ASIHTTPRequest requestWithURL:url];
[requestToResume setTemporaryFileDownloadPath:tempfilePath];
[requestToResume setDownloadDestinationPath:filePath];
[requestToResume setDelegate:self];
[requestToResume setDownloadProgressDelegate:self];
[requestToResume setUserInfo:dictInfo];
// This file has part of the download in it already
[requestToResume setAllowResumeForFileDownloads:YES];
[requestToResume setDidFinishSelector:#selector(requestDone:)];
[requestToResume setDidFailSelector:#selector(requestWentWrong:)];
[requestToResume startAsynchronous];
In the above code we get the url of the song from the dictionary which was set as userInfo of the request and now we get these details for resuming the request. When we resume the request the file will be downloaded from the point it was paused, hence it will solve the purpose of resuming the file download.

Resume downloading a file using ASIHTTPRequest gives error

I am using ASIHTTPRequestfor resuming the downloading of a file gives the error as below and the Resume code is given at the bottom:
Error Domain=ASIHTTPRequestErrorDomain Code=8 "Decompression of /Users/xxxx/Library/Application Support/iPhone Simulator/4.3.2/Applications/6E0D8E0F-08FD-440C-82F6-8E39E219884E/Documents/myPdf.pdf.download failed with code -3" UserInfo=0x4c6a8e0 {NSLocalizedDescription=Decompression of /Users/xxxx/Library/Application Support/iPhone Simulator/4.3.2/Applications/6E0D8E0F-08FD-440C-82F6-8E39E219884E/Documents/myPdf.pdf.download failed with code -3}
Starting download as below:
-(IBAction)startDownload:(id)sender
{
NSURL *url = [NSURL URLWithString:self.sourcePath];
ASIHTTPRequest *req =[[ASIHTTPRequest alloc] initWithURL:url];
[request setDownloadDestinationPath:self.destinationPath];
// This file has part of the download in it already
[request setTemporaryFileDownloadPath:self.temporaryPath];
[req setDownloadProgressDelegate:self];
[req setDelegate:self];
[req startAsynchronous];
self.request = req;
}
and Pause Downloading as below:
-(IBAction)pauseDownload:(id)sender
{
// Cancels an asynchronous request
[request cancel];
// Cancels an asynchronous request, clearing all delegates and blocks first
// [request clearDelegatesAndCancel];
}
and Resume Download as below:
- (IBAction)resumeDownload:(id)sender
{
NSURL *url = [NSURL URLWithString:
self.sourcePath];
ASIHTTPRequest *request1 = [ASIHTTPRequest requestWithURL:url];
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
NSError *err;
NSDictionary *fileDict = [[NSFileManager defaultManager] attributesOfItemAtPath:destinationPath error:&err];
NSLog(#"file Dict: %#", fileDict);
NSLog(#"size: %#",[fileDict valueForKey:NSFileSize]);
NSInteger nSize =[[fileDict valueForKey:NSFileSize] intValue];
// unsigned long long int size1 = [[fileDict valueForKey:NSFileSize] intValue];
NSString *size = [NSString stringWithFormat:#"bytes=%d", nSize];
NSLog(#"file size: %#",size);
[dict setValue:size forKey:#"Range"];
[request1 setRequestHeaders:dict];
// NSString *downloadPath = #"/Users/ben/Desktop/my_work_in_progress.txt";
// The full file will be moved here if and when the request completes successfully
[request1 setDownloadDestinationPath:self.destinationPath];
// This file has part of the download in it already
[request1 setDownloadProgressDelegate:self];
[request1 setDelegate:self];
[request1 setTemporaryFileDownloadPath:self.temporaryPath];
[request1 setAllowResumeForFileDownloads:YES];
[request1 startAsynchronous];
self.request = request1;
//The whole file should be here now.
// NSString *theContent = [NSString stringWithContentsOfFile:downloadPath];
}
And I set the "Range" HTTP header field to the corresponding file size. The same file on server supports download pause, resume on the app http://itunes.apple.com/us/app/download-manager-pro-lite/id348573579?mt=8
How to implement the Resuming a download
Thanks in advance.
You should refer How to Pause and Resume Downloading Files with ASIHTTP Request in iPhone and

iPhone [request setTimeoutInterval:10] not working, app freezes

When I chnage to port number I'm connecting to to test the timout, my app freezes.
I am calling [request setTimeoutInterval:10];, which I assume should be 10 seconds. But, the app hangs. Could it have something to do with it being a local server?
Code:
// call this when program first starts
-(void) nSendMessage : (NSString *) name Password: (NSString *) password page: (NSString *) page
{
// set the url
NSString *address = #"http://localhost:1075/update";
address=[ address stringByAppendingString: page];
NSMutableURLRequest *request =
[[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString:address]];
// post or get
[request setHTTPMethod:#"POST"];
// data to send
NSString *postString = #"username=iusername&password=ipassword";
NSString *sendString=[postString stringByReplacingOccurrencesOfString:#"iusername" withString: name];
sendString=[sendString stringByReplacingOccurrencesOfString:#"ipassword" withString: password];
[request setValue:[NSString
stringWithFormat:#"%d", [sendString length]]
forHTTPHeaderField:#"Content-length"];
[request setHTTPBody:[sendString
dataUsingEncoding:NSUTF8StringEncoding]];
[request setTimeoutInterval:10];
[[NSURLConnection alloc]
initWithRequest:request delegate:self];
//
//THE PROGRAM FREEZES HERE
//
NSData *urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *response = [[NSString alloc] initWithData:urlData encoding:NSASCIIStringEncoding];
// Phrase repl
[self nUpdateDisplay:response];
}
Your question looks like a dupe of this one:
iPhone SDK: URL request not timing out
So to summarise: the timeout lower limit is at least four minutes, even if you pass in a smaller value.
And as detailed at the above link, using the asynchronous method is usually the best option. If you use synchronous, as you are doing above, and you're in the main runloop, you will block your UI completely, which will cause the 'hang' effect.

Objective-C and ASIHTTPRequest - response string problems

I'm using the ASIHTTPRequest package to send some data from the iPhone to my server and then when saved on server I recieve a response (a string) containing a url that I want to load in a webview. In theory this should be simple, but in reality I can't get this work at all. Seems to be some problems with encoding of the string I guess. If I NSLog out the response it seems to be totally fine, but it just refuses to load in the webview.
This is my request (been playing around with compression and encoding):
NSURL *url = [NSURL URLWithString:#"xxx"];
ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithURL:url] autorelease];
[request setFile:imageData forKey:#"photo"];
[request setDelegate:self];
[request setDidFinishSelector:#selector(requestDone:)];
[request setDidFailSelector:#selector(requestWentWrong:)];
[request setAllowCompressedResponse:NO];
[request setDefaultResponseEncoding:NSUTF8StringEncoding];//NSISOLatin1StringEncoding
[request start];
And this is my responder:
- (void)requestDone:(ASIHTTPRequest *)request{
NSString *response = [request.responseString];
NSLog(#"web content: %#", response);
[webView loadSite:response];
}
The NSLog seems fine, but site just won't load. Tried sending an NSString variable like NSString *temp = #"http://www.google.se"; to the loadSite function and that works fine, so the problem is not with the loading itself.
Would greatly appriciate any pointers or help in the obj-c jungle :)
/f
Try to do the following:
NSString *response = [[request responseString] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
It will trim all whitespaces and newlines.
so turns out that a response is automatically ended with a \n (new linebreak). this didn't show up when logging the variable, neither when writing it to a textfield but when converting it to a urlobject and logging that i found it. debugging once again pays off ;)
woups, my responder is of course:
- (void)requestDone:(ASIHTTPRequest *)request{
NSString *response = [request responseString];
NSLog(#"web content: %#", response);
[webView loadSite:response];
}
