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();
/ *授权部分被剥离,因为这个例子中不需要* /
/ * ... * /
}
/ * *
*获取已认证用户的最新活动。
*
* @throws IOException如果无法调用API
* /
private static void getActivity()throws IOException {
//已知的公共活动ID
String activityId =z12gtjhq3qn2xxl2o224exwiqruvtda0i;
/ *通过ID获取明确的公共活动* /
//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){
/ * ... * /
}
}
/ **
*打印在命令行上指定的活动。
*
* @param activity显示
* /
的活动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 answers:+ activity.getPlusObject()。getReplies()。getTotalItems());

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();
