接口返回数据是一条数据和一个数组的区别

例1：

[我：me] ---------->api url stock/me 
with token:WudYqKDKzijeMcrmYcP.qFiGgIavFs0u response:{"desc":"","name":"1460630091572","balance":100000000,"sex":"","nickName":"1460630091572","logo":"http://115.28.189.219/player_icon/19.png","watched":0,"phone":""} 

public static void getMe() {

try{
String getMe_URL = "http://115.28.189.219:9898/stock/me?access_token="+access_token;
//创建连接
URL url = new URL(getMe_URL);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("GET");
connection.setUseCaches(false);
connection.setInstanceFollowRedirects(true);

//connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
connection.setRequestProperty("Content-Type","application/json; charset=UTF-8");

connection.connect();

//读取响应
BufferedReader reader = new BufferedReader(new InputStreamReader(
connection.getInputStream()));
String lines;
StringBuffer sb = new StringBuffer("");
while ((lines = reader.readLine()) != null) {
lines = new String(lines.getBytes(), "utf-8");
sb.append(lines);
}
System.out.println(sb);


////////解析返回数据

String retString = sb.toString();

JSONObject retObject = JSONObject.fromObject(retString);

System.out.println(retObject.getString("balance"));


reader.close();
// 断开连接
connection.disconnect();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

例2：

public static void myInvestment() {

try{
String myInvestment_URL = "http://115.28.189.219:9898/stock/products?access_token="+access_token;
//创建连接
URL url = new URL(myInvestment_URL);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("GET");
connection.setUseCaches(false);
connection.setInstanceFollowRedirects(true);

//connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
connection.setRequestProperty("Content-Type","application/json; charset=UTF-8");

connection.connect();
System.out.println("%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%");

//读取响应
BufferedReader reader = new BufferedReader(new InputStreamReader(
connection.getInputStream()));
String lines;
StringBuffer sb = new StringBuffer("");
while ((lines = reader.readLine()) != null) {
lines = new String(lines.getBytes(), "utf-8");
sb.append(lines);
}
System.out.println(sb);


////////解析返回数据

String retString = sb.toString();

// JSONObject retObject = JSONObject.(retString);

JSONArray authorJsonArray = JSONArray.fromObject(retString);

for(int i = 0; i < authorJsonArray.size();i++)
{
JSONObject retObject0 = authorJsonArray.getJSONObject(i);

System.out.println(retObject0.getString("desc"));
}


System.out.println("%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%");


reader.close();
// 断开连接
connection.disconnect();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

解析返回数据部分是区别，返回数组时，应按照例2写
