Android新浪微博获取评论信息、发表评论、转发微博等

 首先前面一节中说过，获取用户的微博信息，这里简单介绍下获取微博的评论信息，以及对微博进行评论，转发微博等.

     OAuth认证，这里就不多说了，

     我说名一下接口：

     获取微博的评论列表接口： http://api.t.sina.com.cn/statuses/comments.json 

      我们这里需要把微博ID做为参数请求，这个ID我们可以根据前面一节解析用户的微博信息得到.

     对微博进行评论接口：http://api.t.sina.com.cn/statuses/comment.json

      我们需要把微博的id，与我们的评论comment做为参数进行请求.

      微博转发接口：http://api.t.sina.com.cn/statuses/repost.json

    这里我们只需要微博的id.

    下面是实现部分代码：

/***
	 * 获取用户的评论
	 * 
	 * @param requstURL
	 *            请求url
	 * @param blog_id
	 *            微博id
	 * @return JSON(String)
	 * @throws OAuthMessageSignerException
	 * @throws OAuthExpectationFailedException
	 * @throws OAuthCommunicationException
	 * @throws ClientProtocolException
	 * @throws IOException
	 * @throws JSONException
	 */
	public static String getJSONBlogsComments(String requstURL, String blog_id)
			throws OAuthMessageSignerException,
			OAuthExpectationFailedException, OAuthCommunicationException,
			ClientProtocolException, IOException, JSONException {
		String jsonArray = null;
		HttpResponse httpResponse;
		HttpClient client = new DefaultHttpClient();
		HttpPost httpPost = new HttpPost(requstURL);
		getTokenAndTokenSecret();
		CommonsHttpOAuthConsumer authConsumer = new CommonsHttpOAuthConsumer(
				Constant.weiBo.consumerKey, Constant.weiBo.consumerSecret);
		authConsumer.setTokenWithSecret(token, tokenSecret);

		List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
		nameValuePairs
				.add(new BasicNameValuePair(Constant.weiBoTag.id, blog_id));
		httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
		httpPost.getParams().setBooleanParameter(
				CoreProtocolPNames.USE_EXPECT_CONTINUE, false);

		authConsumer.sign(httpPost);
		httpResponse = client.execute(httpPost);

		if (HttpStatus.SC_OK == httpResponse.getStatusLine().getStatusCode()) {
			jsonArray = EntityUtils.toString(httpResponse.getEntity());
		}
		Log.i(Constant.TAG, jsonArray);
		return jsonArray;
	}

	 */
	public static boolean CommentBlogByID(String blog_ID, String comment,
			String requstURL) throws ClientProtocolException, IOException,

		authConsumer.sign(httpPost);

		httpResponse = client.execute(httpPost);

		if (HttpStatus.SC_OK == httpResponse.getStatusLine().getStatusCode()) {
			return true;
		}
		return false;
	}

      其实主要是Oauth认证，我们只需要相应的Token 和Tokensecret，这些接口没有什么，相信大家看过新浪API都会的.

     下面是实现后的效果：

              获取用微博的评论列表                                            获取用户的评论列表

              微博评论界面                                                   刚评论的信息

                                   转发的微博.
