通过iPhone连接到服务器的SSL错误

Question

我正在尝试使用我的应用程序建立到服务器的HTTPS连接.但由于跟随错误,连接失败

错误域= NSURLErrorDomain代码= -1200"发生SSL错误,无法与服务器建立安全连接." UserInfo = 0x612eb30 {NSErrorFailingURLStringKey = https:myURL.com/signup,NSLocalizedRecoverySuggestion =您是否还要连接到服务器？,NSErrorFailingURLKey = https:myURL.com/signup,NSLocalizedDescription =发生了SSL错误并且安全连接到服务器无法生成.,NSUnderlyingError = 0x612eb70"发生SSL错误,无法建立与服务器的安全连接."}

连接到服务器的代码是

-(IBAction) handleEvents:(id)sender
 {
    if ((UIButton*)sender == submit) {

    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;


    NSLog(@"Begin");
    NSData *urlData;
    NSURLResponse *response;
    NSError *error;

    NSString *url =[[NSString alloc]initWithFormat:@"%@signup",baseURL];
    NSURL *theURL =[NSURL URLWithString:url];
    NSMutableURLRequest *theRequest =[NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:0.0f];
    [theRequest setHTTPMethod:@"POST"];
    NSString *theBodyString = [NSString stringWithFormat:@"emailId=%@&mobileNumber=%@&appId=%@&password=%@&firstName=%@&lastName=%@"
                               ,@"abc@example.com",@"919879876780",@"bf1c7a6b3d266a7fe350fcfc4dda275211c13c23" ,@"qwerty" , @"Dev" , @"Sri"];
    NSData *theBodyData = [theBodyString dataUsingEncoding:NSUTF8StringEncoding];

    [theRequest setHTTPBody:theBodyData];
    urlData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&response error:&error];
    }
}

我的委托方法是

- (void)handleError:(NSError *)error
{
NSLog(@"----->%@",error);
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
  [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;   

 }

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
   }

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge (NSURLAuthenticationChallenge *)challenge {  
    NSLog(@"check auth");
    [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
   }

我被困在这里,无法找到任何出路.

任何形式的帮助将不胜感激.

提前致谢!!

Answer 1

iOS 9强制使用HTTPS的连接为TLS 1.2以避免最近的漏洞.在iOS 8中,甚至支持未加密的HTTP连接,因此旧版本的TLS也没有出现任何问题.作为解决方法,您可以将此代码段添加到Info.plist:

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

因此,您将禁用App Transport Security.希望这很有帮助.

Answer 2

由于长时间没有得到答复,我的研究和当前开发表明代码完全适用于连接,它的服务器上的证书未经授权CA签名.所以有这种问题的人检查证书在服务器端是否有效.

希望这会有所帮助!!
