Question

当我尝试使用面子书注册时，我遇到了问题，请在日志中获取以下内容

  07-11 10:15:07.757: W/com.facebook.Session(8910): Should not pass a read permission (user_likes) to a request for publish or manage authorization

07-11 10:15:08.797: V/log_tag(8910): Token=false

我按照了facebook的正确文档甚至使用代码生成SHA密钥并将其放在控制台上禁用沙盒启用脸书登录禁用深层链接但仍然没有运气我用于脸书的代码如下：

facebookBtn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            Session.openActiveSession(SignIn_Rewards.this, true, new Session.StatusCallback() {

                // callback when session changes state
                @Override
                public void call(Session session, SessionState state,
                        Exception exception) {

                    Log.v("log_tag", "Token=" + session.getAccessToken());
                    Log.v("log_tag", "Token=" + session.isOpened());

                    Session currentSession = Session.getActiveSession();

                    if (currentSession == null || currentSession.getState().isClosed()) 
                    {
                         session = new Session.Builder(SignIn_Rewards.this).build();
                        Session.setActiveSession(session);
                        currentSession = session;
                    }


                    else if(!currentSession.isOpened())
                    {
                        //Ask for username and password
                        OpenRequest op = new Session.OpenRequest(SignIn_Rewards.this);

                        op.setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK);
                        op.setCallback(null);

                        List<String> permissions = new ArrayList<String>();
                        permissions.add("publish_stream");
                        permissions.add("user_likes");
                        permissions.add("email");
                        permissions.add("user_birthday");
                        permissions.add("user_location");
                        op.setPermissions(permissions);


                        session = new Session.Builder(SignIn_Rewards.this).build();
                        Session.setActiveSession(session);
                        session.openForPublish(op);
                    }
                    else if (session.isOpened()) {




                        // make request to the /me API
                        Request.executeMeRequestAsync(session,
                                new Request.GraphUserCallback() {

                                    // callback after Graph API response with user
                                    // object
                                    @Override
                                    public void onCompleted(GraphUser user,
                                            Response response) {
                                        if (user != null) {
                                           /* TextView welcome = (TextView) findViewById(R.id.welcome);
                                            welcome.setText("Hello "
                                                    + user.getName() + "!");*/
                                            finish();

                                            Log.d("User Name",""+user.getName()+"     "+user.getFirstName()+"    "+user.getLastName()+"    "+user.getProperty("email")+user.getBirthday()+user.getLocation().getProperty("name"));
                                        }
                                    }
                                });
                    }
                }
            });


        }
    }) ;

请在我错的地方纠正我

我一般都会发现这个问题是因为生成了错误的哈希密钥。而不是做所有keytool的东西尝试在你的onCreate之一粘贴此代码以生成正确的密钥并将其粘贴到Facebook上的应用程序部分。

PackageInfo info;
try {
    info = getPackageManager().getPackageInfo("com.you.name", PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md;
        md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String something = new String(Base64.encode(md.digest(), 0));
        //String something = new String(Base64.encodeBytes(md.digest()));
        Log.e("hash key", something);
    }
} catch (NameNotFoundException e1) {
    Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
    Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
    Log.e("exception", e.toString());
}

这将在logcat中生成密钥。检查this以了解更多正确生成哈希密钥的方法
