如何获得Google Plus中某篇文章的评论？ [英] How to get the comments of a post in Google Plus?

问题描述

我如何获得Google +上的帖子的评论？

我已经获取帖子的内容和回复的数量。

  public class示例{
 
 private static Plus unauthenticatedPlus; 
 
 public static void main（String [] args）throws IOException {
 
 try {
 setupTransport（）; 
 
 getActivity（）; 
} catch（HttpResponseException e）{
 / * ... * / 
} 
} 
 
 / ** 
 *设置传输我们的API调用。 
 * @throws java.io.IOException当传输无法创建时
 * / 
 private static void setupTransport（）throws IOException {
 //这是一个未经验证的Plus目的。如果您
 //不需要使用/ me /路径段来发现当前用户的
 // ID，则可以使用此代码跳过OAuth流程。 
 unauthenticatedPlus = Plus.builder（Util.TRANSPORT，Util.JSON_FACTORY）
 //当我们不指定访问令牌时，我们必须指定我们的API密钥，而不是
 //我们使用JsonHttpRequestInitializer 
 .setJsonHttpRequestInitializer（new JsonHttpRequestInitializer（）{
 @Override $ b $ public void initialize（JsonHttpRequest jsonHttpRequest）throws IOException {
 PlusRequest plusRequest =（PlusRequest）jsonHttpRequest; 
 plusRequest .setKey（Auth.GOOGLE_API_KEY）; 
} 
}）。build（）;

 //我们无需通过身份验证即可获取此活动
尝试{
 Activity activity = unauthenticatedPlus 。.activities（）得到（activityId）.execute（）; 
 show（activity）; 
} catch（HttpResponseException e）{

} 
}

 System.out.println（id： + activity.getId（））; 
 System.out.println（url：+ activity.getUrl（））; 
 System.out.println（content：+ activity.getPlusObject（）。getContent（））;

解决方案
获取活动评论需要 
 
 
创建一个新的额外请求。 -java-client.googlecode.com/hg/apis/plus/v1/index.htmlrel =nofollow>  PlusRequest 实例：
  Plus.Comments.List listComments = plus.comments（）。list（activityId）; 
  
执行请求并将其解析为  CommentFeed  ：
  CommentFeed commentFeed = listComments.execute（）; 
  
获取 评论 实例：
  List< Comment> comments = commentFeed.getItems（）; 
  
 
How can I get the comments of a post on Google+?

I am already getting the content of the post and the number of replies.
public class Sample {

  private static Plus unauthenticatedPlus;

  public static void main(String[] args) throws IOException {

    try {
      setupTransport();

      getActivity();
    } catch (HttpResponseException e) {
      /* ... */
    }
  }

  /**
   * Setup the transport for our API calls.
   * @throws java.io.IOException when the transport cannot be created
   */
   private static void setupTransport() throws IOException {
       // Here's an example of an unauthenticated Plus object. In cases where you
       // do not need to use the /me/ path segment to discover the current user's
       // ID, you can skip the OAuth flow with this code.
       unauthenticatedPlus = Plus.builder(Util.TRANSPORT, Util.JSON_FACTORY)
           // When we do not specify access tokens, we must specify our API key instead
           // We do this using a JsonHttpRequestInitializer
           .setJsonHttpRequestInitializer(new JsonHttpRequestInitializer() {
               @Override
               public void initialize(JsonHttpRequest jsonHttpRequest) throws IOException {
                 PlusRequest plusRequest = (PlusRequest) jsonHttpRequest;
                 plusRequest.setKey(Auth.GOOGLE_API_KEY);
               }
       }).build();

      /* Authorization part stripped, as this is not needed in this sample */
      /* ... */
  }

  /**
   * Get the most recent activity for the authenticated user.
   *
   * @throws IOException if unable to call API
   */
  private static void getActivity() throws IOException {
    // A known public activity ID
    String activityId = "z12gtjhq3qn2xxl2o224exwiqruvtda0i";

    /* Get an explicit public activity by ID */
    // We do not need to be authenticated to fetch this activity
    try {
      Activity activity = unauthenticatedPlus.activities().get(activityId).execute();
      show(activity);
    } catch (HttpResponseException e) {
      /* ... */
    }
  }

  /**
   * Print the specified activity on the command line.
   *
   * @param activity the activity to show
   */
  private static void show(Activity activity) {
    System.out.println("id: " + activity.getId());
    System.out.println("url: " + activity.getUrl());
    System.out.println("content: " + activity.getPlusObject().getContent());
    System.out.println("No of replies: " + activity.getPlusObject().getReplies().getTotalItems());
  }
}
Thanks in advance.
解决方案
Getting the comments of an activity needs an extra request to the Google+ API.

Create a new PlusRequest instance:
Plus.Comments.List listComments = plus.comments().list(activityId);
Execute the request and parse it into a CommentFeed:
CommentFeed commentFeed = listComments.execute();
Get a list of Comment instances:
List<Comment> comments = commentFeed.getItems();
