Question

我跟随facebook（https://developers.facebook.com/docs/android/share）关注facebook android共享教程。该应用程序运行正常，我可以登录Facebook点击演示共享按钮。所以这是我的应用程序：

使用facebook登录
更新了facebook会话对象，并在会话对象中保存了以下权限：user_likes, user_friends, user_status, basic_info
现在，我想分享一些东西。因此，用户单击共享按钮，并且发出了名为publish_actions的附加权限的请求

以下代码执行此请求：

public class MainActivity extends Activity {

    private Button shareButton;
    private UiLifecycleHelper uiHelper;
    private static final List<String> PERMISSIONS = Arrays.asList("publish_actions");
    private static final String PENDING_PUBLISH_KEY = "pendingPublishReauthorization";
    private boolean pendingPublishReauthorization = false;

...
    private void publishStory() {
        Session session = Session.getActiveSession();
        if( session != null) {
            List<String> permissions = session.getPermissions();
            if(!isSubsetOf(PERMISSIONS, permissions)) {
                pendingPublishReauthorization = true;
                Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(this, PERMISSIONS);
//Request the new permission here. The answer is processed in onSessionStateChange() method
                session.requestNewPublishPermissions(newPermissionsRequest);
                return;
            }

...

    private void onSessionStateChange(Session session, SessionState state, Exception exception) {
//since the session is already open we enter this if branch
        if (state.isOpened()) {
            shareButton.setVisibility(View.VISIBLE);
//The result of state.equals(SessionState.OPENED_TOKEN_UPDATED) is false which indicates that the session object has not been updated (as far as I understand the fb api)
            Log.e(TAG, "state.equals(SessionState.OPENED_TOKEN_UPDATED) = " + state.equals(SessionState.OPENED_TOKEN_UPDATED));
//Output all the current permission the session has (publish_actions is not included here)
            List<String> permissions = session.getPermissions();
            Iterator<String> it = permissions.iterator();
            Log.e(TAG, "Content of list:");
            while(it.hasNext())
                Log.e(TAG, "permission = " + it.next());
//Since the OPENED_TOKEN_UPDATED has not been updated nothing further happens here              
            if (pendingPublishReauthorization && state.equals(SessionState.OPENED_TOKEN_UPDATED)) {
                pendingPublishReauthorization = false;
                publishStory();
            }
        } else if (state.isClosed()) {
            shareButton.setVisibility(View.INVISIBLE);
        }
    }

所以，虽然这似乎是正确的，但必定存在一些错误。未授予publish_actions权限，但我不明白为什么。只有现有权限保留publish_actions。

进一步说明：我已经阅读了一些问题，说明应该出现一个额外的弹出窗口，要求用户授予权限。然而，在我的情况下，这不会发生。也许这就是问题？如果是这样，我需要做什么才能获得弹出窗口？

更新：我还从github尝试了以下要点：https://gist.github.com/vishalpawale/5556996 由于完全相同的原因，此示例代码失败。它没有获得任何publish_action权限。似乎是Facebook SDK中的实际错误？

对于发布权限，您应该在应用设置中发送请求并发送以供审核，请参阅https://developers.facebook.com/docs/apps/review/

Answer 2

如果您使用Facebook sdk 3.14.x +，那么在4月30日之后，facebook已经更改了应用程序测试和提交过程。发布有关许可相关的答案。查看this链接

Answer 3

我们在这里遇到了同样的问题。

尝试使用：

Session.getActiveSession().refreshPermissions();

这将刷新

上可用的权限列表

List<String> permissions = session.getPermissions();

它仅适用于Facebook注册的开发者用户或通过Facebook App Dashboard注册的测试用户。

这对我们有用。

它只返回读权限，而不是写权限。试试下面的代码段

    final Bundle permBundle = new Bundle();
    permBundle.putCharSequence("permission", "publish_actions");
    GraphRequest request = new GraphRequest(
            AccessToken.getCurrentAccessToken(),
            "/me/permissions", permBundle, HttpMethod.GET,
            new GraphRequest.Callback() {
                @Override
                public void onCompleted(GraphResponse graphResponse) {
                    Log.d(TAG, "response2: " + graphResponse.getJSONObject());
                    try {
                        JSONArray permList = (JSONArray) graphResponse.getJSONObject().get("data");
                        if(permList.length() == 0){
                            // no data for perms, hence asking permission
                            askForFBPublishPerm();
                        }else{
                            JSONObject permData = (JSONObject) permList.get(0);
                            String permVal = (String) permData.get("status");
                            if(permVal.equals("granted")){
                                postToFB();
                            }else{
                                askForFBPublishPerm();
                            }
                        }
                    } catch (JSONException e) {
                        Log.d(TAG, "exception while parsing fb check perm data" + e.toString());
                    }

                }
            }
    );
    request.executeAsync();
