java - 在 Android 中将视频上传到 Facebook 时权限被拒绝

Question

我正在编写一个 android 应用程序来上传和分享 facebook 上的视频。我的代码如下:

 public void doShareVideo(View view) {
        List<String> permissionNeeds = Arrays.asList("publish_actions","publish_pages");
        //this loginManager helps you eliminate adding a LoginButton to your UI
        LoginManager manager = LoginManager.getInstance();

        manager.logInWithPublishPermissions(this, permissionNeeds);

        Uri videoFileUri = Uri.parse("file:///storage/emulated/0/Movies/Untitled.mp4");
        ShareVideo video = new ShareVideo.Builder()
                .setLocalUrl(videoFileUri)
                .build();
        ShareVideoContent content = new ShareVideoContent.Builder()
                .setVideo(video)
                .setContentTitle("Video shared from my android apps")
                .build();

        ShareApi.share(content, new FacebookCallback<Sharer.Result>() {
            @Override
            public void onSuccess(Sharer.Result result) {

            }

            @Override
            public void onCancel() {

            }

            @Override
            public void onError(FacebookException error) {
                error.printStackTrace();
            }
        });
    }

但是我在运行时收到错误信息:

我使用 Facebook SDK:com.facebook.android:facebook-android-sdk:4.6.0请帮助我，非常感谢。

对于@Fyodor Volchyok，我已经根据您的建议更改了我的代码，但我没有任何反应。登录Facebook并成功批准权限后，LogCat中无日志信息或无错误显示。我的新代码如下:

public class ShareVideoActivity extends AppCompatActivity {

    private static final String LOG_TAG = "ShareVideo";
    private CallbackManager callbackManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        FacebookSdk.sdkInitialize(this.getApplicationContext());
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_share_video);

        callbackManager = CallbackManager.Factory.create();
        LoginManager loginManager = LoginManager.getInstance();
        loginManager.registerCallback(callbackManager,
                new FacebookCallback<LoginResult>() {
                    @Override
                    public void onSuccess(LoginResult loginResult) {
                        // it would be nice here to check loginResult.getRecentlyGrantedPermissions() for requested permissions
                        Log.d(LOG_TAG, "Success " + loginResult.getRecentlyGrantedPermissions().toString());
                        Uri videoFileUri = Uri.parse("file:///storage/emulated/0/Movies/Untitled.mp4");
                        ShareVideo video = new ShareVideo.Builder()
                                .setLocalUrl(videoFileUri)
                                .build();
                        ShareVideoContent content = new ShareVideoContent.Builder()
                                .setVideo(video)
                                .setContentTitle("Video shared from my android apps")
                                .build();

                        ShareApi.share(content, new FacebookCallback<Sharer.Result>() {
                            @Override
                            public void onSuccess(Sharer.Result result) {

                            }

                            @Override
                            public void onCancel() {

                            }

                            @Override
                            public void onError(FacebookException error) {
                                error.printStackTrace();
                            }
                        });
                    }

                    @Override
                    public void onCancel() {
                        // App code
                    }

                    @Override
                    public void onError(FacebookException exception) {
                        // App code
                    }
                });
        List<String> permissionNeeds = Arrays.asList("publish_actions", "publish_pages");
        loginManager.logInWithPublishPermissions(this, permissionNeeds);
    }
}

你对我有什么新的建议吗？提前致谢。 (我可以分享图片和链接，但遇到视频问题)

Answer 1

您似乎正在尝试在尚未授予权限的情况下上传视频。尝试以下操作:

1. 为登录管理器设置回调。
2. 使用 LoginManager 登录。
3. (最重要!)等待用户登录。您将通过回调收到通知。
4. 检查是否授予权限。
5. 如果是，请上传。

大概的结果是这样的:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(this.getApplicationContext());

    callbackManager = CallbackManager.Factory.create();

    LoginManager.getInstance().registerCallback(callbackManager,
    new FacebookCallback < LoginResult > () {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // it would be nice here to check loginResult.getRecentlyGrantedPermissions() for requested permissions

            Uri videoFileUri = Uri.parse("file:///storage/emulated/0/Movies/Untitled.mp4");
            ShareVideo video = new ShareVideo.Builder()
                .setLocalUrl(videoFileUri)
                .build();
            ShareVideoContent content = new ShareVideoContent.Builder()
                .setVideo(video)
                .setContentTitle("Video shared from my android apps")
                .build();

            ShareApi.share(content, new FacebookCallback < Sharer.Result > () {
                @Override
                public void onSuccess(Sharer.Result result) {

                }

                @Override
                public void onCancel() {

                }

                @Override
                public void onError(FacebookException error) {
                    error.printStackTrace();
                }
            });
        }

        @Override
        public void onCancel() {
            // App code
        }

        @Override
        public void onError(FacebookException exception) {
            // App code   
        }
    });
    LoginManager.getInstance().logInWithPublishPermissions(this, permissionNeeds);
}

是的，这段代码可以而且应该改进，但整个想法就在这里。
