mkfile创建caf文件error

Question

 NSString *documentsPath =[self dirDoc];
        NSString *goufirefilePath = [documentsPath stringByAppendingPathComponent:filePath];
        QNUploadOption *opt = [[QNUploadOption alloc] initWithMime:@"audio/*;application/*" progressHandler:nil params:nil checkCrc:NO cancellationSignal:nil];
        QNUploadManager *upManager = [[QNUploadManager alloc] init];
        [upManager putFile:goufirefilePath key:key token:token
                  complete: ^(QNResponseInfo *info, NSString *key, NSDictionary *resp) {
                      callback(@[[NSNull null], [NSNumber numberWithInt:info.statusCode]]);
                  } option:opt];

我通过ios SDK的putFile方法上传caf文件, 当文件很小时，可以上传成功，当caf文件大时，api会自动分片上传，但最后在合并成一个文件的时候报错了。
报错信息如下，提示是mimeType类型不匹配，但文件小的时候又可以上传成功...不知道怎么回事...求助...

Answer 1

代码中：initWithMime:@"audio/;application/"

这个，是需要一个需要确定的mimetype类型，就是文件上传后，最后在七牛指定的mimetype

一般caf文件的mimetype是这个吧：

audio/x-caf
