I am using ASIHTTPRequest in my project and i have a problem with iPhone 3G.
i send a request to :
NSURL* pageURL = [NSURL URLWithString:#"https://accounts.google.com/ServiceLogin?service=sj"];
loginPageRequest = [[ASIHTTPRequest alloc] initWithURL:pageURL];
[loginPageRequest setTimeOutSeconds:30];
[loginPageRequest setDelegate:self];
[loginPageRequest startAsynchronous];
and in other devices i get a responde to :
- (void)requestFinished:(ASIHTTPRequest *)request
and in iPhone 3G i get a lot of times :
- (void)requestFailed:(ASIHTTPRequest *)request
with error MSG : The request timed out
i set the the request timeout to 30 seconds.
any idea why it happen?
I also had this problem on iPhone 3G!
I figured out it was a HTTP*S* (SSL) problem. My "valid" certificate was flagged as invalid.
You might add [request setValidatesSecureCertificate:NO]; to your request.
If you are lucky you have the same problem. :)

I have to load all the required details from server in my application. eg; I wants to load countries detail from the following URL.
https://sub.domain.com//members/phone/XML_list_countries.php
But I am getting following error. But the same request working in Simulator.
ERROR
Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo=0x3b8d10 {NSErrorFailingURLStringKey=https://secure.nymgo.com//members/softphone/XML_list_countries.php, NSErrorFailingURLKey=https://secure.nymgo.com//members/softphone/XML_list_countries.php, NSLocalizedDescription=The request timed out., NSUnderlyingError=0x3b5090 "The request timed out."}
CODE
NSURL *url=[NSURL URLWithString:#"https://secure.nymgo.com//members/softphone/XML_list_countries.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"GET"];
NSURLConnection *_connection = [[NSURLConnection alloc] initWithRequest:_request delegate:self];
if(!_connection){
NSLog(#"Can not make this request.");
}
I have implemented all the required delegate methods.
NOTE: My device is working in Wifi with proxy settings.
I don't know what is going wrong. Please help me to resolve this issue.
Have you Implement :
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;
Also Refer this SO post.
You can use the ASIHTTPRequest framework also.
I have tested the same code in different iPhone 3G and iPhone 4 devices. it is working fine.
NOTE: I searched lot in google. I got lot of result. One of the result is like "some iPhone 3G is not supporting for HTTPS. So I decided to test it in different devices.
I need a little help here!!!
If string 'url' contains the address to web server, how do i check whether my web server is up or down?
I got some codes to check Internet connectivity. But even if we have internet connectivity how do we know server is up or not? Is there any better way to do that?
Thank You
You could do a request,
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:20.0];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest
delegate:self];
Now if you implement (along with all other delegate methods)
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
you will get either succes or error.
Post a request, get the response. If you get a response, the server is up, if not its down..
I am trying to download a xyz.config file which is created using iPhone Configuration utlity, via code.
NSString *urlString = #"http://xxxxx:xxx/ms/servlet/ConfigServer?userid=xxx&pwd=xxx&emailid=xxxxx";
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
receivedData = [[NSMutableData data] retain];
} else {
// Inform the user that the connection failed.
}
Then, didReceiveData, didReceiveResponse are written. Finally,
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(#"Succeeded! Received %d bytes of data",[receivedData length]);
NSString *responseString = [[NSString alloc] initWithData:receivedData encoding:NSUTF8StringEncoding];
NSLog(#"Response : %#", responseString );
// release the connection, and the data object
[receivedData release];
[connection release];
}
With the above code, i'm getting response as string of the complete configuration file. But my Aim to download this file as raw data, which will automatically launch device profile to ask for installing this profile.
NOTE: I am able to provide the same URL in Safari browser on the device, and download the
raw file directly to install it on the device. I don't want to use Safari browser to download it, it should be done via my communication code.
I also tried with ASIHTTPRequest like below, but unable to download that file directly from the URL via this code as well.
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setRequestMethod:#"GET"];
[request startSynchronous];
Please help!
Thank you.
The Mobile Safari browser app on the iOS has a lot more freedom than your app. Case in point, on the latest iOS 4.3, Mobile Safari has the Nitro JavaScript engine which boost 2x performance increase. But the UIWebView which is available to your app doesn't have that engine. Your app is in a sandbox, therefore, you cannot write outside of that box.
I'm using the ASIHTTPRequest lib in my iOS app to make RESTful requests to my Rails 3 web app. I seeing a weird and somewhat consistent error the 1st time I try to make a POST request to my web app, but then the POST request works fine the on the second attempt. The exact error is...
Error Domain=ASIHTTPRequestErrorDomain Code=1 "A connection failure occurred" UserInfo=0xb513740 {NSUnderlyingError=0xb5135a0 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1005.)", NSLocalizedDescription=A connection failure occurred}
And here's my ASIHTTPRequest code for making the POST request...
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"http://myrails3app.heroku.com/tournaments/%d/register.json", tid]];
__block ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setRequestMethod:#"POST"];
[request addPostValue:username forKey:#"username"];
[request setCompletionBlock:^
{
NSData *responseData = [request responseData];
NSLog(#"Success!");
}];
// Set the code to be called when the request fails
[request setFailedBlock:^
{
NSError *error = [request error];
NSLog(#"Error: %#", [error localizedDescription]);
}];
// Start the request
[request startAsynchronous];
It's worth mentioning that when it errors out, it errors out incredibly quickly! Also, for what it's worth, my Rail 3 app that I'm making the POST request to is hosted on Heroku. Your thoughts?
Thanks so much for your wisdom!
This issue I had a lot of hard time to figure out why. The problem resides in ASIHTTPRequest itself (iOS), not the rails code.
To make a long story short, the problem is specific to the use of persistent connection for every request sent by ASIHTTPRequest.
While this is good for GET requests, most server implementation does not allow persistent connection to be used with POST request.
I didn't really have time to investigate it deeply on the server side of things but I think that the problem resides with the 100-Continue header that should be sent (and which isn't) with request that has body attached to it (hence PUT/POST). If you want to have a deeper look at what I'm talking about go have a read at the spec sheet: http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html
So the persistent connection used by ASIHTTPRequest wait for a 100 response to be sent, which is never sent. so it ends up being timed out.
A fix is to set persistentConnection to NO with your post requests like the following:
ASIHTTPRequest *req = [ASIHTTPRequest requestWithURL:url];
req.shouldAttemptPersistentConnection = NO;
Secure Connection Failed
An error occurred during a connection to login.yahoo.com.
SSL received a record with an incorrect Message Authentication Code.
(Error code: ssl_error_bad_mac_read)
The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
Please contact the web site owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.
On iOS 5.1, even after upgrading ASIHTTPRequest to ASIHTTPRequestVersion = #"v1.8.1-61 2011-09-19" still needed:
ASIHTTPRequest *req = [ASIHTTPRequest requestWithURL:url];
req.shouldAttemptPersistentConnection = NO;
i also had to set response setHeader Connection to "close" in by Java servlet
response.setHeader("Connection", "close");
I am using the ASIHTTPRequest class in order to communicate with a web service and get a response. This is how I send a request to the server
NSString *str = [NSString stringWithFormat:#"%#verifyLogin.json", serverUrl];
NSURL *url = [NSURL URLWithString:[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
ASIHTTPRequest *request = [[[ASIHTTPRequest alloc] initWithURL:url] autorelease];
[request addRequestHeader:#"Content-Type" value:#"text/x-gwt-rpc; charset=utf-8"];
NSDictionary* data = [NSDictionary dictionaryWithObjectsAndKeys:emailId, #"username", pwd, #"password", nil];
[request appendPostData: [[data JSONFragment] dataUsingEncoding: NSUTF8StringEncoding]];
[request setRequestMethod:#"POST"];
[request setDelegate:self];
[request setDidFinishSelector: #selector(gotLoginResponse:)];
[request setDidFailSelector: #selector(loginRequestFailed:)];
[networkQueue addOperation: request];
[networkQueue go];
The control immediately goes to the error routine and the error description and domain are
Unable to start HTTP connection and ASIHTTPRequestErrorDomain
I can get the same request to work via a desktop tool for checking HTTP requests so I know the settings are all correct.
Can someone please tell me what I am missing here while sending the request?
Thanks.
As I commented earlier;
in your first line it says
"%verifyLogin.json". Shouldn't that
be; "%#verifyLogin.json" ????
For me I forgot to add http:// as i was testing locally. But after adding http it ran successfully
Can you check the status code of the request when it fails? I recently dealt with a JSON user authentication issue with ASI-HTTP-Request where the first request would always fail with Status Code 0 and some sort of underlying network connection failure (as if it wasn't connected to the internet, but clearly was).
I was able to solve it by setting that particular request to not attempt to use a persistent connection.
So try that first!
