NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813) iOS

Question

Currently I am consuming a soap web service using block in ios my source code is as follows

NSString *xml = requestXMLToSent;

NSString *msgLength = [NSString stringWithFormat:@"%lu", (unsigned long)[xml length]];
NSURL *serviceURL = [NSURL URLWithString: url];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:serviceURL];

[urlRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[urlRequest addValue: serviceURL forHTTPHeaderField:@"SOAPAction"];
[urlRequest addValue:msgLength  forHTTPHeaderField:@"Content-Length"];
[urlRequest setHTTPBody: [xml dataUsingEncoding:NSUTF8StringEncoding]];
[urlRequest setHTTPMethod:@"POST"];

[NSURLConnection sendAsynchronousRequest:urlRequest queue:[[NSOperationQueue alloc]init] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {


    if (connectionError == NULL) {

        NSHTTPURLResponse * httpResponse = (NSHTTPURLResponse *) response;
        NSInteger statuscode = httpResponse.statusCode;
        if (statuscode == 200) {

            NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
            NSLog(@"response String  : %@",responseString);


        }else{
            NSLog(@"%@",response);

        }




    }else{

        NSLog(@"There is an error in URL connection and the Error is : %@",connectionError);
    }

I am getting the following error @ console

NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813)

There is an error in URL connection and the Error is : Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid.

Answer 1

Server is throwing SSL certificate error. For the sake of testing, you can add the following code to the appDelegate: + (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host { return YES; }

This will bypass the SSL error

Note: works for NSURLConnection & UIWebView, but not for WKWebView

Edited:

For iOS 9, above procedure don't work. Add the following snippet in info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

Answer 2

I assume you use https scheme in your serviceURL and your test server has problems with SSL certificate. If so and you trust it, implement next methods in your NSURLConnection delegate's:

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
    return YES;
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
    if([challenge.protectionSpace.host isEqualToString:@"127.0.0.1"] /*check if this is host you trust: */ )
       [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
}

To have a delegate initialize your NSURLConnection for example with initWithRequest:delegate:startImmediately: method.
