在Android中向Facebook上传视频时被拒绝的许可
在Android中向Facebook上传视频时被拒绝的许可
提问于 2015-10-10 07:14:30
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();
}
});
}但是我在运行时会收到错误消息：

对于@Fyodor，我已经更改了代码，作为您的建议，但我什么也没有发生。登录Facebook并成功批准权限后，LogCat中不会显示任何日志信息或错误。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);
}
}你有什么新建议给我吗？提前谢谢。(我可以分享图片和链接，但遇到了视频问题)

当你还没有被授予权限的时候，你似乎在尝试上传视频。尝试以下几点：
- 为LoginManager设置回调。
- 使用LoginManager登录。
- (最重要的！)等待用户登录。您将通过回调得到通知。
- 检查是否授予权限。
- 如果是的话，上传。
近似结果如下所示：
@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，这个代码可以而且应该得到改进，但是整个想法就在这里。

原因是将视频上传到facebook需要一个名为"upload_video“的权限，如果这个权限不是由用户授予的，您就不能上传视频。
下面是确保权限的示例代码：
//Path to the video, Ex: path = Environment.getExternalStorageDirectory() + File.separator + "myVideo.mp4";
String path;
//get the current active facebook session
Session session = Session.getActiveSession();
//If the session is open
if(session.isOpened()) {
//Get the list of permissions associated with the session
List<String> permissions = session.getPermissions();
//if the session does not have video_upload permission
if(!permissions.contains("video_upload")) {
//Get the permission from user to upload the video to facebook
Session.NewPermissionsRequest newPermissionsRequest = new Session
.NewPermissionsRequest(this, Arrays.asList("video_upload"));
session.requestNewReadPermissions(newPermissionsRequest);
}
//Create a new file for the video
File file = new File(path);
try {
//create a new request to upload video to the facebook
Request videoRequest = Request.newUploadVideoRequest(session, file, new Request.Callback() {
@Override
public void onCompleted(Response response) {
if(response.getError()==null)
{
Toast.makeText(MainActivity.this, "video shared successfully", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(MainActivity.this, response.getError().getErrorMessage(), Toast.LENGTH_SHORT).show();
}
}
});
//Execute the request in a separate thread
videoRequest.executeAsync();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
//Session is not open
else {
Toast.makeText(getApplicationContext(), "Please login to facebook first", Toast.LENGTH_SHORT).show();
