OC语言
调用这个方法

[upManager putData:data key:strMp3 token:self.qiNiuTokenStr

              complete: ^(QNResponseInfo *info, NSString *key, NSDictionary *resp) {

                  NSLog(@"%@", info);

                  NSLog(@"%@", resp);


  } option:nil];

获得了这个值

2016-08-22 10:45:48.351 FanHeIOS2.0[22106:3864544] {

    hash = Fj3F3KQUY6fDTKj1DDmytuzrKu7M;

    key = "/Users/renhao/Library/Developer/CoreSimulator/Devices/ABBDC6C2-F398-40DE-BC7E-158F61075E2F/data/Containers/Data/Applicat ... cord.mp3";

}

我现在做到这一步，在调用这个方法吗

[upManager putFile:resp[@"key"] key:resp[@"key"] token:self.qiNiuTokenStr complete:^(QNResponseInfo *info, NSString *key, NSDictionary *resp) {

                      NSLog(@"info ===== %@", info);

                      NSLog(@"resp ===== %@", resp);

                  } option:uploadOption];


              } option:nil];

调用这个方法报错

2016-08-22 10:45:55.683 FanHeIOS2.0[22106:3864544] info ===== 

2016-08-22 10:45:59.771 FanHeIOS2.0[22106:3864544] resp ===== (null)

这是为神马
