抄寫OAuth Java Google日曆api。 NO客戶端庫

Question

我有一些與dropox交互的代碼。那就是：

package rest;

// Step 1: Create Dropbox Account

public class DropBoxRestClient { 
    // Access codes #1: per application used to get access codes #2 
    private static final String API_APP_KEY = "NOT_OF_YOUR_CONCERN";

    public static void main(String[] args) { 

     Scanner in = new Scanner(System.in); 

     OAuthService service = new ServiceBuilder()

     } catch(ParseException e) {

（此代碼工作完全BTW）
我很痛苦知道的是，我能否做類似的事情與使用劃線谷歌的API。問題是我找不到NO APP_KEY或APP_ID。我在Google Developers Console中創建了一個項目，憑證OAUTH作爲Web App，並且沒有這樣的APP密鑰或ID。

Answer 1

你是幾乎沒有，從https://developers.google.com/console/help/new/#generatingoauth2

轉至谷歌開發者控制檯。
選擇一個項目，或創建一個新項目。
在左側的邊欄中，展開API &驗證。接下來，點擊API。在API列表中，確保您使用的所有API顯示狀態爲ON。
在左邊的邊欄中，選擇憑證。
點擊創建新的客戶端ID。
爲您的項目選擇適當的應用類型並輸入所需的其他信息。
