I have a tomcat server that uses a self signed SSL certificate and is running a web service. I am trying to connect to the web service with Restkit. However, I am getting an error related to certificate validity. Here is my code:
NSURL *url=[NSURL URLWithString:baseURL];
RKClient *client = [RKClient clientWithBaseURL:url];
client.disableCertificateValidation=YES;
RKRequest *request = [client requestWithResourcePath:[NSString stringWithFormat:#"/addEvent?deviceID=%#&eventID=%#",deviceID,eventID]];
request.disableCertificateValidation=YES;
request.delegate=self;
RKResponse *response = [request sendSynchronously];
This request fails with the following error:
2013-01-09 15:11:53.931 Mobile_ACPL[5761:907] The certificate for this server is invalid. You might be connecting to a server that is pretending to be “notify.acpl.lib.in.us” which could put your confidential information at risk.
I get this error even though I have set disableCertificateValidation to YES. How can I get this working?
EDIT: I attempted adding the certificate as shown here: https://github.com/RestKit/RestKit/pull/131
I still get the same result.
EDIT 2: It looks like the error message is being set at this line in RKRequest.m:
payload = [NSURLConnection sendSynchronousRequest:_URLRequest returningResponse:&URLResponse error:&error];
NSURLConnection does not cater for authentication challenges in synchronous calls. You need to make asynchronous calls for this to work.
In my case, I was setting disableCertificateValidation on RKClient but I was using a RKObjectManager which used a different RKClient. The following line, placed after the RKObjectManager initialization, did the trick:
[RKObjectManager sharedManager].client.disableCertificateValidation = YES;
if you are using RestKit using
client.allowsInvalidSSLCertificate = YES;
won't work, instead do this:
if you added rest kit manually to your project, click on RestKit.xcodeproj go to project > Build Settings > Preprocessor Macros
and add _AFNETWORKING_ALLOW_INVALID_SSL_CERTIFICATES_=1
thats finished.

I requested to server with POST method, and server response me 401 status code. i have error 1012 and my response is nil.
//Send request
NSData* data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
Therefore i found some code for disable and change security mode in iOS Objective C request but is don't know how to use it and where set code.
please help
AFSecurityPolicy *policy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
[policy setValidatesDomainName:NO];
[policy setAllowInvalidCertificates:YES];
[policy setValidatesCertificateChain:NO];
According to the docs:
NSURLErrorUserCancelledAuthentication = -1012
Here is the error list
More over HTTP status code 401 = Unauthorized
First of all, do not disable certificate validation. It will not solve your problem. The server is rejecting the client's authentication, not the other way around.
Second, your problem is that the user's credentials are not in the keychain and you aren't providing delegate methods to provide credentials yourself. I'm not sure precisely how you do that with the AF API, but you can read about the way you would do it directly at https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/URLLoadingSystem/Articles/AuthenticationChallenges.html and use that as a starting point for understanding what is happening under the hood.
My request is
request_ = [[ASIFormDataRequest requestWithURL:requestUrl] retain];
[request_ setDelegate:self];
[request_ setRequestMethod:#"GET"];
[request_ setTimeOutSeconds:HTTP_TIME_OUT];
[request_ startAsynchronous];
But the response from the server is
HTTP Status 405 - Request method 'GET' not supported. The specified HTTP method is not allowed for the requested resource (Request method 'GET' not supported).
Please note that the url doesn't have any "GET" parameters along with it even though it is a get request. The thing is I am getting the proper response from the server when simply I take the request URL in a browser or when I call it using "HttpRequester"(a Firefox add-on to test http requests - well I'm sure you know that). What could have went wrong?
Thanks in advance.

For GET requests, use ASIHTTPRequest.
ASIFormDataRequest is for POST requests.
However, if all you need is a simple GET request, why bother with ASI? You can do this in a dispatch_async block:
dispatch_async(<some_queue>, ^{
NSError * error = nil;
NSString * response = [NSString stringWithContentsOfURL: stringWithContentsOfURL: requestUrl error: &error];
[self performSelectorOnMainThread: #selector(processResult:) withObject: response waitUntilDone: NO];
});
Solved it. It was because of the absence of the header parameter "Accept" in requests that have been made. Once it was added, everything worked like a charm.
Also replaced ASIFormDataRequest with ASIHTTPRequest(that one was a silly mistake).
Seems it is a server side issue. Please verify if all the header parameters as required by the server are there in request.
why you create a ASIFormDataRequest aka POSTRequest and set the RequestMethod to GET?
If you want to make a GET Request use ASIHTTPRequest instead.
I am trying to send a suggestion from my app to a php file on my web server, I have tested the php script in my browser which sends an email to the user and stores the suggestion in my database, which all works fine.. And when running the following script I get a successful connection via IOS however i do not receive the results in my database..
NSString *post = [NSString stringWithFormat:#"http://blahblah.com/suggest.php?s=%#&n=%#&e=%#", suggestion, name, email];
// Create the request.
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:post]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
// create the connection with the request
// and start loading the data
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
NSLog(#"Connection establisted successfully");
} else {
NSLog(#"Connection failed.");
}
I have checked all the strings and encoded all spaces with %20 etc.. Can anyone see any glaringly obvious reason why my script won't work?
What is the easiest way to make a HTTP request from my app without opening safari?
You problem is that you're creating the connection, but are not sending the actual "connect" request. Instead of
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
try using this piece of code:
NSURLResponse* response = nil;
NSData* data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil]
This is quick and dirty solution, but keep in mind that while this connection is in progress, your UI thread will appear to be frozen. The way around it is to use asynchronous connection method, which is a bit more complicated than the above. Search web for NSURLConnection send asynchronous request - the answer is there.
I'm having the strangest issue right now with google app engine. I'm sending a POST request from iOS and google app engine instead invokes the GET handler.
I've sandboxed this one situation for testing and can't get it figured out. I have an iOS app that just sends a request. And I've commented out everything on GAE except for the service. The service only logs a parameter and returns.
The iOS app I've tried using two different ways of sending the request. Neither works.
iOS Code:
/*
NSURL * url = [NSURL URLWithString:#"http://beermonster-gngrwzrd.appspot.com/TestParameter"];
ASIFormDataRequest * _fdrequest = [[ASIFormDataRequest alloc] initWithURL:url];
[_fdrequest setPostValue:#"hello" forKey:#"testkey"];
[_fdrequest startAsynchronous];
*/
NSURL * __url = [NSURL URLWithString:#"http://beermonster-gngrwzrd.appspot.com/TestParameter"];
NSMutableURLRequest * __request = [NSMutableURLRequest requestWithURL:__url];
[__request setHTTPMethod:#"POST"];
NSString * post = [NSString stringWithFormat:#"testkey=hello"];
[__request setHTTPBody:[post dataUsingEncoding:NSUTF8StringEncoding]];
[NSURLConnection sendSynchronousRequest:__request returningResponse:nil error:nil];
My App engine handler:
class TestParameter(webapp.RequestHandler):
def post(self):
logging.debug(self.request.get("testkey"))
self.response.out.write(self.request.get("testkey"))
print self.request.get("testkey")
def get(self):
logging.debug("get")
logging.debug(self.request.get("testkey"))
self.response.out.write(self.request.get("testkey"))
The output in the GAE logs shows the "get" code path which isn't correct.
Any ideas why POST requests would come into GAE as a GET? Is there some configuration in GAE that I missed?
Thanks!
Check the entry in app.yaml for the script that handles "/TestParameter". Does it specify "secure: always"? If it does and you make a non-secure connection you will get a 302 redirecting to the secure version.
To fix this either make your post over HTTPS or remove "secure: always" from the entry in app.yaml.
From what I can tell if you want to send POST requests to GAE. Make sure you do it on https. If you make the request on a non-https attempt, it sends back a 302 redirect to the https version of the request. But if whatever you're using to send the request doesn't correctly handle 302's it might resend the request incorrectly.
Can anyone give me a hint why I can not login into my service? I dont get an response to my delegate. The service is working. If I call the url in my browser I get a login (Browser receives a cookie) and then I can call request on my service:
Here is my Code:
RKClient *client =[RKClient clientWithBaseURL:#"https://myserverinstance/mobileapp/"];
NSString *loginString = #"SSO.login?application=myAppName&language=en&username=MyUserName&password=MyPassword&permanentLogin=true";
[RKClient setSharedClient:client];
if([[RKClient sharedClient] isNetworkAvailable]){;
NSLog(#"Network is available");
[[RKClient sharedClient] get:loginString delegate:self];
I'm assuming that the typos in your posted code (e.g. if([[RKClient sharedClient] isNetworkAvailable]){;) do not exist in your actual project.
Are your SSL certificates self-signed? If so, you'll need to set the RESTKIT_SSL_VALIDATION preprocessor directive. You'll also need to link against Security.framework.
If your certificates are signed by a common authority, then you should post more information about your problem. Turn RestKit logging on with RKLogConfigureByName("RestKit/Network", RKLogLevelTrace); and see if that provides any hints to where the problem really lies.
