基于新浪微博api的微博分享功能实现

首先应该拿到新浪微博开发的api，然后细读其中的一些文档规范，这样我们就能知道第三方应用要想实现分享内容到新浪微博平台，

1.第三方应用需要在新浪微博的开放平台通过审核，拿到

<span style="font-family:Microsoft YaHei;font-size:14px;">client_ID=*****
client_SERCRET=*****</span>
配置到config.properties，信息如下：

<span style="font-family:Microsoft YaHei;font-size:14px;">client_ID=*****
client_SERCRET=*****
redirect_URI=http://apps.weibo.com/ceshidemo
baseURL=https://api.weibo.com/2/
accessTokenURL=https://api.weibo.com/oauth2/access_token
authorizeURL=https://api.weibo.com/oauth2/authorize
rmURL=https://rm.api.weibo.com/2/
response_type=code</span>
2.拿着从新浪微博开放平台获取的client_ID、client_SERCRET去获取AccessToken，

3.然后拿着获取的AccessToken去访问新浪微博，发送一篇心得微博或者是获取当前用户信息等等

下面是代码：

<span style="font-family:Microsoft YaHei;font-size:14px;">public class WeiBoUtil2 extends WeiBoUtil {

public static final String POST_WEIBO_URL_WITH_CONTENT = "https://api.weibo.com/2/statuses/update.json?";

private static final Logger logger = Logger.getLogger(WeiBoUtil2.class);

public static Map<String, String> header = new HashMap<String, String>();

static {

header.put("Accept-Language", "zh-CN,zh;q=0.8");

header.put("User-Agent", "test sina api");

header.put("Accept-Charset", "utf-8;q=0.7,*;q=0.3");
}

/**
* 获取当前用户信息
*
* @param uid
*
*/
public static void showUser(String uid) {
Weibo weibo = new Weibo();
AccessToken accessToken = weibo.getAccessToken();// 通过code回去通行令类
Users um = new Users();
um.client.setToken(accessToken.getAccessToken());// 设置通行令然后发布微博
try {
User user = um.showUserById(uid);// 获取用户
Log.logInfo(user.toString());
} catch (WeiboException e) {
e.printStackTrace();
}
}

/**

public static void findFriendsByScreenName(String name) {
Weibo weibo = new Weibo();
AccessToken accessToken = weibo.getAccessToken();
Friendships fm = new Friendships();
fm.client.setToken(accessToken.getAccessToken());
try {
UserWapper users = fm.getFollowersByName(name);
for (User u : users.getUsers()) {
Log.logInfo(u.toString());
}
} catch (WeiboException e) {
Log.logErr(null+ ":" + e.getMessage());
}
}
