获取CFNetwork SSLHandshake失败（-9806）错误

我正在尝试使用我的url

NSDictionary *landingDetails=[appDelegate landingPage]; NSString *devinf=[UIDevice currentDevice].systemVersion; NSString *appVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"]; NSMutableDictionary *reqDict=[NSMutableDictionary dictionary]; [reqDict setObject:@"refillByScan" forKey:@"appId"]; [reqDict setObject:@"extest1" forKey:@"affId"]; [reqDict setObject:[landingDetails objectForKey:@"token"] forKey:@"token"]; [reqDict setObject:@"0124400-59382" forKey:@"rxNo"];//medication or prescription id [reqDict setObject:@"appName://handleControlFromScanRefill" forKey:@"appCallBackScheme"]; [reqDict setObject:@"callBackAction" forKey:@"appCallBackAction"]; [reqDict setObject:@"chkExpRx" forKey:@"act"]; [reqDict setObject:@"" forKey:@"trackingId"]; [reqDict setObject:devinf forKey:@"devinf"]; [reqDict setObject:appVersion forKey:@"appver"]; NSString *landingUrl=[landingDetails objectForKey:@"landingUrl"];//my url request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:landingUrl]]; NSString *jsonRequest = [reqDict JSONRepresentation]; NSLog(@"jsonRequest is %@", jsonRequest); NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]]; [request setHTTPMethod:@"POST"]; [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody: requestData]; con=[[NSURLConnection alloc]initWithRequest:request delegate:self]; [con start]; 

我在日志中收到此错误

Answer 1

FWIW：我得到了相同的错误号，这是由于证书过期，所以这是该问题的另一个潜在来源。

Answer 2

使用具有散列函数SHA512的证书时，iOS 8上存在错误，最好使用SHA256。 我坚持这个错误好几个星期了。

Answer 3

通常当我得到CFNetwork SSLHandshake失败 – （*）它因为我的本地wifi网络（设备连接到网络而不是互联网）

在另一个网络上再试一次（3G对我来说是最快的解决方案）
