Question

我正在尝试在我的应用中添加一个超级基本的Soundcloud功能，以使用他们的UI上传单个.wav文件。我按照他们的指南，我真的不需要在裸骨共享菜单之外的任何东西，所以我假设这个代码将工作：

              NSURL *trackURL = [[NSURL alloc] initWithString:[docsDir stringByAppendingPathComponent:fileToShare]];

            SCShareViewController *shareViewController;
            shareViewController = [SCShareViewController shareViewControllerWithFileURL:trackURL
                                                                      completionHandler:^(NSDictionary *trackInfo, NSError *error){

                                                                          if (SC_CANCELED(error)) {
                                                                              NSLog(@"Canceled!");
                                                                          } else if (error) {
                                                                              NSLog(@"Ooops, something went wrong: %@", [error localizedDescription
                                                                                                                         ]);
                                                                          } else {
                                                                              // If you want to do something with the uploaded
                                                                              // track this is the right place for that.
                                                                              NSLog(@"Uploaded track: %@", trackInfo);
                                                                          }
                                                                      }];

            // If your app is a registered foursquare app, you can set the client id and secret.
            // The user will then see a place picker where a location can be selected.
            // If you don't set them, the user sees a plain plain text filed for the place.
            [shareViewController setFoursquareClientID:@"<foursquare client id>"
                                          clientSecret:@"<foursquare client secret>"];

            // We can preset the title ...
            [shareViewController setTitle:@"Funny sounds"];


            // ... and other options like the private flag.
            [shareViewController setPrivate:NO];

            // Now present the share view controller.
            [self presentModalViewController:shareViewController animated:YES];

            [trackURL release];

但是我在调试控制台中出现HTTP 422错误：

2016-02-29 11:04:47.129 synthQ[801:443840] parameters: {
    "track[asset_data]" = "/var/mobile/Containers/Data/Application/EE58E5CA-B30C-44EB-B207-EB3368263319/Documents/bb.wav";
    "track[downloadable]" = 1;
    "track[post_to][]" = "";
    "track[sharing]" = public;
    "track[tag_list]" = "\"soundcloud:source=synthQ\"";
    "track[title]" = "Funny sounds";
    "track[track_type]" = recording;
}
2016-02-29 11:04:47.164 synthQ[801:444011] -[NXOAuth2PostBodyStream open] Stream has been reopened after close
2016-02-29 11:04:47.373 synthQ[801:443840] Upload failed with error: HTTP Error: 422 Error Domain=NXOAuth2HTTPErrorDomain Code=422 "HTTP Error: 422" UserInfo={NSLocalizedDescription=HTTP Error: 422}

有没有人有任何想法可能会出错？

谢谢！

Answer 1

在SoundCloud中获取HTTP 422错误的原因之一是：

如果您是第一次尝试使用新帐户上传文件，则需要验证您的电子邮件地址以完成SoundCloud注册才能上传文件。

这个错误可能还有其他原因，但是对于我的情况来说就是这种情况并且解决了这个问题。

Answer 2

上传曲目时无法引用外部资源。您因此需要将轨道下载到您的计算机，然后执行实际上传到SoundCloud。

我设法通过使用另一个将音频文件作为NSData对象传递的构造函数来解决这个问题：

shareViewController = [SCShareViewController shareViewControllerWithFileData:[NSData dataWithContentsOfFile:[docsDir stringByAppendingPathComponent:fileToShare]]
                                                                          completionHandler:^(NSDictionary *trackInfo, NSError *error){

                                                                              if (SC_CANCELED(error)) {
                                                                                  NSLog(@"Canceled!");
                                                                              } else if (error) {
                                                                                  NSLog(@"Ooops, something went wrong: %@", [error localizedDescription
                                                                                                                             ]);
                                                                              } else {
                                                                                  // If you want to do something with the uploaded
                                                                                  // track this is the right place for that.
                                                                                  NSLog(@"Uploaded track: %@", trackInfo);
                                                                              }
                                                                          }];
