Question

我是Google Project新手，我必须在我的项目中集成Google Calendar和Google Task。为此，我正在考虑[https://developers.google.com/google-apps/calendar/instantiate][1]。我已经添加了：

谷歌播放服务作为图书馆谷歌的API服务日历-V3-rev81的Java-1.18.0-RC。

但它显示错误＆＃34;无法解析com.google.api.client.auth.oauth2.draft10.AuthorizationRequestUrl类型。它是从所需的.class文件＆＃34;

间接引用的

这是我的代码：

    String clientId = "YOUR_CLIENT_ID";
    String clientSecret = "YOUR_CLIENT_SECRET";

    // Or your redirect URL for web based applications.
    String redirectUrl = "urn:ietf:wg:oauth:2.0:oob";
    String scope = "https://www.googleapis.com/auth/calendar";

    // Step 1: Authorize -->
    String authorizationUrl = new GoogleAuthorizationRequestUrl(clientId,
            redirectUrl, scope).build();

    // Point or redirect your user to the authorizationUrl.
    System.out.println("Go to the following link in your browser:");
    System.out.println(authorizationUrl);

    // Read the authorization code from the standard input stream.
    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    System.out.println("What is the authorization code?");
    String code = in.readLine();
    // End of Step 1 <--

    // Step 2: Exchange -->
    AccessTokenResponse response = new GoogleAuthorizationCodeGrant(
            httpTransport, jsonFactory, clientId, clientSecret, code,
            redirectUrl).execute();
    // End of Step 2 <--

    GoogleAccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource(
            response.accessToken, httpTransport, jsonFactory, clientId,
            clientSecret, response.refreshToken);

    com.google.api.services.calendar.Calendar service = new com.google.api.services.calendar.Calendar.Builder(
            httpTransport, accessProtectedResource, jsonFactory).setApplicationName(
            "AppName").build();

感谢任何形式的帮助。

此错误可能是由于API控制台中的配置错误造成的。确保您的项目设置为＆＃34;已安装的应用程序。＆＃34;
