GCD没有得到的网页内容得到的字符串部署在互联网上

Question

我正在后台线程模块获得当前时间显示在网页上为10-06-2014 16:19:11。当涉及到执行时，没有数据被获取。你能告诉我如何创建inputStream和阅读web内容吗?假设https链接正常工作给出的消息是:此服务器的证书无效。您想要连接到服务器吗?

下面是我的代码

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)， ^{

    dispatch_async(dispatch_get_main_queue(), ^{
        NSURL *jsonURL = [NSURL URLWithString:[NSString stringWithFormat:@"https://dc02.csd-hk.net:8081/GetTime.aspx",nil]];
        NSError *error = nil;
        NSURLRequest *request = [NSURLRequest  requestWithURL:jsonURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:120.0 ];
        NSData *responsedata = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];
        NSString* jsonData = [[NSString alloc] initWithData:responsedata encoding:NSUTF8StringEncoding];
   //     NSString *json = [NSString stringWithContentsOfURL:url   encoding:NSUTF8StringEncoding error:&error];
        if( jsonData.length > 0 )
        {
            NSLog(@"Text=%@", jsonData);
            [ToastView showToastInParentView:self.view withText:jsonData withDuaration:5.0];
        }
        else 
        {
            NSLog(@"Error = %@", error);
        }
    });

});

你的URL无法解析，所以你最好检查两次。
