如果我从终端运行此请求，我通常可以看到JSON请求：

curl -XGET 192.168.0.6:8888/scripts/data/backend2/index.php/name/_all

我的NSURlRequest的代码是这样的：

 NSURLRequest *request = [NSURLRequest requestWithURL:
                             [NSURL URLWithString:@"192.168.0.6:8888/scripts/data/backend2/index.php/name/_all"]];

    [[NSURLConnection alloc] initWithRequest:request delegate:self];

我得到这个错误：

didFailWithError
2013-11-29 22:31:08.164 Ski Greece[607:a0b] Connection failed: Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo=0xcd042d0 {NSErrorFailingURLStringKey=192.168.0.6:8888/scripts/data/backend2/index.php/name/_all, NSErrorFailingURLKey=192.168.0.6:8888/scripts/data/backend2/index.php/name/_all, NSLocalizedDescription=unsupported URL, NSUnderlyingError=0xdbdcc70 "unsupported URL"}

我怎样才能调用该网址？
