如何在Facebook上設置權限上傳照片？

如何在Facebook上設置應用程序以發送圖片？我已經ACCESS_TOKEN，APP_ID和secret_id但是當你在這種方法的應用程序中調用：如何在Facebook上設置權限上傳照片？

FacebookType publishPhotoResponse = facebookClient.publish("me/photos", FacebookType.class, 
     BinaryAttachment.with("albumID", bs), 
     Parameter.with("message", "description"));

得到這個錯誤：

com.restfb.exception.FacebookNetworkException: A network error occurred while trying to communicate with Facebook: Facebook request failed (HTTP status code null)

有人能解釋一下如何設置一個接一個Facebook應用程序？

如果您需要延長權限，您可以在這裏關注guide。從帖子：

讓我們先定義什麼權限，我們將需要

// List of additional write permissions being requested 
private static final List<String> PERMISSIONS = Arrays.asList("publish_stream, publish_actions"); 

// Request code for reauthorization requests. 
private static final int REAUTH_ACTIVITY_CODE = 100; 

// Flag to represent if we are waiting for extended permissions 
private boolean pendingAnnounce = false;

我們將首先檢查，如果我們有所需的所有權限。如果不是，我們用我們請求的一組權限創建一個新的ReauthorizeRequest。這會將我們的應用以外的用戶引導至Facebook應用或瀏覽器以確認權限。當用戶確認請求時，他被重定向回到我們的應用程序，onActivityResult調用了重新授權請求被調用的Activity。

private void handleAnnounce() { 
    pendingAnnounce = false; 
    Session session = Session.getActiveSession(); 

    if (session == null || !session.isOpened()) { 
     return; 
    } 

    List<String> permissions = session.getPermissions(); 
    if (!permissions.containsAll(PERMISSIONS)) { 
     pendingAnnounce = true; // Mark that we are currently waiting for confirmation of publish permissions 
     session.addCallback(this); 
     requestPublishPermissions(this, session, PERMISSIONS, REAUTH_ACTIVITY_CODE); 
     return; 
    } 

    // TODO: Publish the post. You would need to implement this method to actually post something 
    publishMessage(); 
} 

void requestPublishPermissions(Activity activity, Session session, List<String> permissions, 
    int requestCode) { 
    if (session != null) { 
     Session.ReauthorizeRequest reauthRequest = new Session.ReauthorizeRequest(activity, permissions) 
      .setRequestCode(requestCode); 
     session.reauthorizeForPublish(reauthRequest); 
    } 
}

如果會話狀態更改，則會處理結果並調用onSessionStateChanged。然後，如果我們的令牌已成功更新並嘗試再次發佈該消息，則檢查該方法。

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    switch (requestCode) { 
    case REAUTH_ACTIVITY_CODE: 
     Session session = Session.getActiveSession(); 
     if (session != null) { 
      session.onActivityResult(this, requestCode, resultCode, data); 
     } 
     break; 
    } 
} 
protected void onSessionStateChange(final Session session, SessionState state, Exception exception) { 
    if (session != null && session.isOpened()) { 
     if (state.equals(SessionState.OPENED_TOKEN_UPDATED)) { 
      // Session updated with new permissions 
      // so try publishing once more. 
      tokenUpdated(); 
     } 
    } 
} 

/** 
* Called when additional permission request is copmleted successfuly. 
*/ 
private void tokenUpdated() { 
    // Check if a publish action is in progress 
    // awaiting a successful reauthorization 
    if (pendingAnnounce) { 
     // Publish the action 
     handleAnnounce(); 
    } 
}
