获取格式错误的访问令牌"t ype":"OAuthException","code":190

Question

我正在编写一个Android应用程序来获取Facebook用户相册和照片,并在我的Android应用程序中显示.我用APP_ID 281846961912565创建了一个Facebook应用程序.

在创建Facebook实例时,我传递此id如下

facebook = new Facebook(APP_ID);

使用此实例,我能够以编程方式登录我的FB帐户帖子,在facebook墙上留言.登录后,我得到一个access_token.

我正在使用访问令牌来获取相册ID facebook.request("https://graph.facebook.com/me/albums?access_token="+facebook.getAccessToken());

现在我明白了 {"error":{"message":"Malformed access token ACCESSTOKENACCESSTOKEN?access_token=ACCESSTOKENACCESSTOKEN","t??ype":"OAuthException","code":190}}

你们中的任何人都可以帮我解决这个问题,并指出我做错了什么.

我的代码如下:

    private static final String[] PERMISSIONS = new String[] { "publish_stream","user_photos" };
public boolean saveCredentials(Facebook facebook) {
    Editor editor = getApplicationContext().getSharedPreferences(KEY,
            Context.MODE_PRIVATE).edit();
    editor.putString(TOKEN, facebook.getAccessToken());
    editor.putLong(EXPIRES, facebook.getAccessExpires());
    return editor.commit();
}

public boolean restoreCredentials(Facebook facebook) {
    SharedPreferences sharedPreferences = getApplicationContext()
            .getSharedPreferences(KEY, Context.MODE_PRIVATE);
    facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
    facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
    return facebook.isSessionValid();
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    facebook = new Facebook(APP_ID);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.facebook_dialog);
    String facebookMessage = getIntent().getStringExtra("facebookMessage");
    if (facebookMessage == null) {
        facebookMessage = "Test wall post";
    }
    messageToPost = facebookMessage;
}

R.layout.facebook_dialog是弹出的对话框,询问是否应该在Facebook上共享消息.如果是,则调用以下方法.

    public void share(View button) {
    if (!facebook.isSessionValid()) {
        loginAndPostToWall();
    } else {
        postToWall(messageToPost);
    }
}
   public void loginAndPostToWall() {
    facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH,
            new LoginDialogListener());
}
   class LoginDialogListener implements DialogListener {
    public void onComplete(Bundle values) {
        saveCredentials(facebook);
        if (messageToPost != null) {
            postToWall(messageToPost);
        }
    }

    public void onFacebookError(FacebookError error) {
        showToast("Authentication with Facebook failed!");
        finish();
    }

    public void onError(DialogError error) {
        showToast("Authentication with Facebook failed!");
        finish();
    }

    public void onCancel() {
        showToast("Authentication with Facebook cancelled!");
        finish();
    }
}

   public void postToWall(String message) {
    Bundle parameters = new Bundle();
    parameters.putString("message", message);
    parameters.putString("description", "topic share");
    try {
        facebook.request("me");
        String response = facebook.request("me/feed", parameters, "POST");
        Log.d("Tests", "got response: " + response);
        if (response == null || response.equals("")
                || response.equals("false")) {
            showToast("Blank response.");
        } else {
            showToast("Message posted to your facebook wall!");
        }
                    getImagesFromUserAlbum();
        finish();


    } catch (Exception e) {
        showToast("Failed to post to wall!");
        e.printStackTrace();
        finish();
    }
}

后来当我做一个`private void getImagesFromUserAlbum(){facebook.getAccessToken();

    JSONArray albumss = null;
    String response = null;
    try {
        response = facebook.request("me/albums");

//`

我收到错误{"error":{"message":"格式错误的访问令牌ACCESSTOKEN？access_token = ACCESSTOKEN","type":"OAuthException","code":190}}

谢谢你的帮助.

上面的代码现在是工作副本.感谢Bartek.

如果您查看文档中的" 错误"页面,您将看到当您获得时error 190,应该授权/重新授权用户.

我怀疑这发生在你身上,因为你第一次登录,然后添加了访问你的应用程序的相册的权限但是没有注销并重新登录.因此,你需要获得一个新的访问令牌,它将授予新的权限到您的申请.
