I have run into a little problem. I am connecting to a webservice that use Basic authentication and now I want the user to either: be able to log out, or that each time the request is made a new authentication is made. Right now the authentication seems to be cached. How do I do this?
I tried to append # at the end, but that did not seem to do the trick. The URL has the following format:
www.example.org/mywebservice/data
NSURL* url = [NSURL URLWithString: #"www.example.org/mywebservice/data"];
NSURLRequest* request = [[NSURLRequest alloc] initWithURL:url];
NSURLConnection* newConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
self.myConnection = newConnection;
[request release];
[newConnection release];
I think you want to clear the cache of the previous requests and every time want to do new request at login. So for that just put below code before doing request for login
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
[storage deleteCookie:cookie];
}
[[NSURLCache sharedURLCache] removeAllCachedResponses];
May help you
Happy Coding :)
I got it to work. I changed NSURLCredentialPersistenceSession to NSURLCredentialPersistenceNone.
NSURLCredential *cred = [[[NSURLCredential alloc] initWithUser:user.username password:user.password
persistence:NSURLCredentialPersistenceNone] autorelease];
Have you tried clearing the Authentication header in your NSURLRequest?
[urlRequest setValue:#"" forHTTPHeaderField:#"Authorization"];

I want to upload (POST) image to server with setkey "FileData" like before (wrote with ASIHTTPRequest and it works)
[self.request setData:imageData withFileName:dateFormatted andContentType:#"image/jpeg" forKey:#"Filedata"];
with AFNetworking I set like below:
NSMutableURLRequest *afRequest = [httpClient multipartFormRequestWithMethod:#"POST" path:#"" parameters:paramsDic constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData:imageData name:#"Filedata" fileName:dateFormatted mimeType:#"image/jpeg"];
}];
seems name not actually works...
How should I set the key? #mattt
Thanks
I figure it out, the problem is I add this line
[afRequest setValue:#"application/x-www-form-urlencoded; charset=UTF8" forHTTPHeaderField:#"Content-Type"];
But I still don't know why, I add this line to other http request and it works, but file upload. I checked server, when do file upload with this line, server received many ... hm... come to think how to describe it, mass letters ...like below:
Content-Type: image/jpeg^M ^M
ÿØÿà^#^PJFIF^#^A^A^#^#^A^#^A^#^#ÿá^#XExif^#^#MM^#*^#^#^#^H^#^B^A^R^#^C^#^#^#^A^#^A^#^#<87>i^#^D^#^#^#^A^#^#^#
hi i am uploading audio/image file as below please check it and its working fine using the ASIHTTPRequest.
NSURL *audiourl = [NSURL URLWithString:#"Your Url"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:audiourl];
NSData *postData = [NSData dataWithContentsOfURL:SoundPath];
//SoundPath is your audio url path of NSDocumentDirectory.
[request addData:postData withFileName:#"mynewfile.png" andContentType:#"image/png" forKey:#"FileData"];
[request setDelegate:self];
[request startasynchronous];
Thanks
I have a UIWebView in my application where I 'm loading the facebook profile of my application. I am using facebook's single sign on SDK(Graph API). And I logged in into facebook in the Safari in background using my application. But When I try loadmy game profile in my application web view still I could see "Log In" and "Sign Up" buttons.
I tried setting cookies, main document URL and relative URL too but no use.
I am adding here my code too here,
NSURL *url = [NSURL URLWithString:#"http://www.facebook.com/myapp" relativeToURL:[NSURL URLWithString:#"http://login.facebook.com"]];
NSMutableURLRequest *request = nil;
if(url)
request = [NSMutableURLRequest requestWithURL:url];
NSArray * availableCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:[NSURL URLWithString:#"http://login.facebook.com"]];
NSDictionary * headers = [NSHTTPCookie requestHeaderFieldsWithCookies:availableCookies];
if(request)
{
[request setHTTPShouldHandleCookies:YES];
[request setMainDocumentURL:[NSURL URLWithString:#"http://login.facebook.com"]];
[request setAllHTTPHeaderFields:headers];//login.facebook.com
[mWebView loadRequest:request];
}
You may be running into the situation I describe in the answer on this page:
Facebook iOS SDK not storing cookies for access
In my ipad project i am using ASIHttpRequest to handle my webservice calls. I am also doing cookie management. My webservice calls are worked fine until i have changed my service cookies all into Secure one.
How to manage Secure cookie with ASIHTTPRequest?
Thanks!
According to the docs:
You can turn off useCookiePersistence, and manage the set of cookies for a particular request manually.
//Create a cookie
NSDictionary *properties = [[[NSMutableDictionary alloc] init] autorelease];
[properties setValue:[#"Test Value" encodedCookieValue] forKey:NSHTTPCookieValue];
[properties setValue:#"ASIHTTPRequestTestCookie" forKey:NSHTTPCookieName];
[properties setValue:#".allseeing-i.com" forKey:NSHTTPCookieDomain];
[properties setValue:[NSDate dateWithTimeIntervalSinceNow:60*60] forKey:NSHTTPCookieExpires];
[properties setValue:#"/asi-http-request/tests" forKey:NSHTTPCookiePath];
NSHTTPCookie *cookie = [[[NSHTTPCookie alloc] initWithProperties:properties] autorelease];
//This url will return the value of the 'ASIHTTPRequestTestCookie' cookie
url = [NSURL URLWithString:#"https://allseeing-i.com/ASIHTTPRequest/tests/read_cookie"];
request = [ASIHTTPRequest requestWithURL:url];
[request setUseCookiePersistence:NO];
[request setRequestCookies:[NSMutableArray arrayWithObject:cookie]];
[request startSynchronous];
//Should be: I have 'Test Value' as the value of 'ASIHTTPRequestTestCookie'
NSLog(#"%#",[request responseString]);
To make the cookie secure, just add this to the properties dictionary:
[properties setValue:#"TRUE" forKey:NSHTTPCookieSecure];
Just remember, secure cookies will only be used with HTTPS requests.
I'm doing an app which retrieves user info, and it does that using a GET request, but I don't know how could I make one. Already tried ASIHTTPRequest with this code:
NSURL *url = [NSURL URLWithString:#"http://forrst.com/api/v2/users/info"];
// Now, set up the post data:
ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithURL:url] autorelease];
[request setPostValue:#"1" forKey:#"id"];
[request setRequestMethod:#"GET"];
// Initiate the WebService request
[request setDelegate:self];
[request startAsynchronous];
But I get this response from forrst:
2011-06-05 16:59:32.189 Forrsty[4335:207] {"resp":{"error":"you must pass either id or username"},"stat":"fail","in":0.0557,"authed":false,"authed_as":false,"env":"prod"}
Which I understand I'm not doing the GET request ok, so how I would do it? Thanks :)
A Get Parameter ?
So why don't you try "http://forrst.com/api/v2/users/info?id=1" ?
[ NSString stringWithFormat:#"http://forrst.com/api/v2/users/info?id=%d", 1 ];
By the way, take a look at this librayry : http://allseeing-i.com/ASIHTTPRequest/
Good luck !
I see the rate limit is 150/hr per IP. This'd be fine, but my application is on a mobile phone network (with shared IP addresses).
I'd like to query twitter trends, e.g. GET /trends/1/json.
This doesn't require authorization, however what if the user first authorized with my application using OAuth, then hit the JSON API?
The request is built as follows:
- (void) queryTrends:(NSString *) WOEID {
NSString *urlString = [NSString stringWithFormat:#"http://api.twitter.com/1/trends/%#.json", WOEID];
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *theRequest=[NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:10.0];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES];
if (theConnection) {
// Create the NSMutableData to hold the received data.
theData = [[NSMutableData data] retain];
} else {
NSLog(#"Connection failed in Query Trends");
}
//NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]];
}
I have no idea how I'd build this request as an authenticated one however, and haven't seen any examples to this effect online.
I've read through the twitter OAuth documentation, but I'm still puzzled as to how it should work.
I've experimented with OAuth using Ben Gottlieb's prebuild library, and calling this in my first viewDidLoad:
OAuthViewController *oAuthVC = [[OAuthViewController alloc]
initWithNibName:#"OAuthTwitterDemoViewController" bundle:[NSBundle mainBundle]];
// [self setViewController:aViewController];
[[self navigationController] pushViewController:oAuthVC animated:YES];
This should store all the keys required in the app's preferences, I just need to know how to build the GET request after authorizing!
Maybe this just isn't possible? Maybe I'll have to proxy the requests through a server side application?
Any insight would be appreciated!
Authorizing through OAuth will provide you an authorization token, which you need to pass to each request you make later on.
Refer to Twitter docs, read about how authorization works.
Okay, after a lot of searching I've managed to figure how to construct a request to the JSON API programmatically in Xcode.
Firstly, you need to use the OAuth demo code to authenticate and authorize your application.
Then, you'll be retrieving the key by doing: [prefs stringForKey:#"authData"] - if this doesn't exist, you haven't been OAuth'd properly.
I had to reverse engineer this by looking through the code of the OAuth library, and while it's easy to use the library for stuff like sending a status update, it doesn't allow you to retrieve trends...:
#import "OAMutableURLRequest.h"
#import "MGTwitterHTTPURLConnection.h"
NSMutableString *dataString;
// Using OAuth:
OAConsumer *consumer = [[OAConsumer alloc] initWithKey:#"YOURCONSUMERKEY"
secret:#"YOURCONSUMERSECRET"];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *authData = [prefs stringForKey:#"authData"];
// [_engine
OAMutableURLRequest *theRequest = [[[OAMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"http://stream.twitter.com/1/statuses/filter.json"]
consumer:consumer
token: (authData) ? [[OAToken alloc] initWithHTTPResponseBody:authData] : nil
realm: nil
signatureProvider:nil] autorelease];
[theRequest setHTTPMethod:#"POST"];
[theRequest setHTTPBody: [httpBody dataUsingEncoding:NSUTF8StringEncoding]];
[theRequest setHTTPShouldHandleCookies:NO];
// Set headers for client information, for tracking purposes at Twitter.
[theRequest setValue:#"Trendy" forHTTPHeaderField:#"X-Twitter-Client"];
[theRequest setValue:#"1.0" forHTTPHeaderField:#"X-Twitter-Client-Version"];
[theRequest setValue:#"http://www.inisdesign.com" forHTTPHeaderField:#"X-Twitter-Client-URL"];
// Set the request body if this is a POST request.
[theRequest prepare];
// Create a connection using this request, with the default timeout and caching policy,
// and appropriate Twitter request and response types for parsing and error reporting.
MGTwitterHTTPURLConnection *connection;
connection = [[MGTwitterHTTPURLConnection alloc] initWithRequest:theRequest
delegate:self
requestType:MGTwitterFollowedTimelineRequest // Wrong type
responseType:MGTwitterStatuses]; // as above - doesnt seem to matter
if (!connection) {
return;
} else {
// [_connections setObject:connection forKey:[connection identifier]];
// [connection release];
dataString = [[NSMutableData data] retain];
[connection start];
}
}
The rest is implemented as a standard URL connection with didReceiveData methods etc..
I haven't verified this is alleviating my rate limiting problems, but hey.. It's a start if anybody has similar problems.
