今天完成的事情：

学习微信API。设计接口文档。

//通过昨天获取的code 来获取用户的openid 然后通过openid 来获取对应的用户信息。这里只是简单的获取，然后代码还有很多改进的地方.没有做到最好。

public static net.sf.json.JSONObject getOpenInfo(String code, String appid, String appsecret)throws Exception{
StringBuffer buffer = new StringBuffer();
 StringBuffer buffer1 = new StringBuffer();
 String url  ="https://api.weixin.qq.com/sns/oauth2/access_token?" +
            "appid="+appid+"&secret="+appsecret+"&code="+code+"&grant_type=authorization_code";
 URL urlConnection = new URL(url);
 HttpURLConnection httpUrlConn  =(HttpURLConnection)urlConnection.openConnection();
 httpUrlConn.setRequestMethod("GET");
 InputStream inputStream = httpUrlConn.getInputStream();
 InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
 BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
 String str = null;
    while ((str = bufferedReader.readLine()) != null) {
        buffer.append(str);
 }
    bufferedReader.close();
 inputStreamReader.close();
 // 释放资源
 inputStream.close();
 httpUrlConn.disconnect();
 net.sf.json.JSONObject jsonObject = net.sf.json.JSONObject.fromObject(buffer.toString());
 //拉取用户信息
 String access_token  =(String)jsonObject.get("access_token");
 String openid =(String)jsonObject.get("openid");
 String userInfoUrl = "https://api.weixin.qq.com/sns/userinfo?access_token="+access_token+"&openid="+openid+"&lang=zh_CN";
 URL urlConnection1 = new URL(userInfoUrl);
 HttpURLConnection httpUrlConn1  =(HttpURLConnection)urlConnection1.openConnection();
 httpUrlConn1.setRequestMethod("GET");
 InputStream inputStream1 = httpUrlConn1.getInputStream();
 InputStreamReader inputStreamReader1 = new InputStreamReader(inputStream1, "utf-8");
 BufferedReader bufferedReader1 = new BufferedReader(inputStreamReader1);
 String str1 = null;
    while ((str1 = bufferedReader1.readLine()) != null) {
        buffer1.append(str1);
 }
    bufferedReader1.close();
 inputStreamReader1.close();
 // 释放资源
 inputStream1.close();
 httpUrlConn1.disconnect();
 net.sf.json.JSONObject jsonObject1 = net.sf.json.JSONObject.fromObject(buffer1.toString());
    return jsonObject1;
}

然后今天还设计了部分接口文档：
这里就截部分截图算了。具体的都在http://rap2.taobao.org     这个东西还挺好用。

明天计划的事情：

把接口文档搞定。
遇到的问题：

设计接口文档 思路不清晰。
收获：

微信API还挺好用。
