如何设置 Google 日历 Java 应用程序

Question

我正在按照 Google 提供的逐步 configuration instructions 进行操作，但由于某种原因，我找不到他们要求我导入的一些包。我的应用程序无法找到的包是（或我的 IDE 抱怨的行）：

import com.google.api.client.auth.oauth2.draft10.AccessTokenResponse;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessProtectedResource;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAccessTokenRequest.GoogleAuthorizationCodeGrant;
import com.google.api.client.googleapis.auth.oauth2.draft10.GoogleAuthorizationRequestUrl;

我似乎找不到装这些的罐子。我的类路径包含：

//The Google Calendar Client API:
google-api-services-calendar-v3-rev16-1.8.0-beta.jar

//And of course the Google API Core:

很遗憾，截至目前，Google 尚未更新 the Java configuration source code。您不需要这些类，正如他们 cmets 中的其他人指出的那样，它们已被弃用。

将“draft10”导入替换为：

import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow;
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.googleapis.auth.oauth2.GoogleTokenResponse;
import com.google.api.services.calendar.CalendarScopes;

然后，将授权代码（从注释“Step 1: Authorize -->”开始）替换为：

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                httpTransport, jsonFactory, clientId, clientSecret,
            Arrays.asList(CalendarScopes.CALENDAR)).setAccessType("online")
                .setApprovalPrompt("auto").build();

String url = flow.newAuthorizationUrl().setRedirectUri(redirectUrl).build();
System.out.println("Please open the following URL in your browser then type the authorization code:");

System.out.println("  " + url);
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String code = br.readLine();

GoogleTokenResponse response = flow.newTokenRequest(code)
                .setRedirectUri(redirectUrl).execute();
GoogleCredential credential = new GoogleCredential()
                .setFromTokenResponse(response);

// Create a new authorized API client
Calendar service = new Calendar.Builder(httpTransport, jsonFactory,
                credential).build();

我遇到了同样的问题，发现 the drive sample code 是最新的。我猜到了我的方式，并使它工作。 “授权码流程”描述为here。
