json对象－json字符串－编码byte[] -传输－解码为字符串－对象
client：
String wholeUrl = String.format("%s?sdkappid=%d&random=%d", URL, SDKAPPID, rnd);
java.net.URL object = new URL(wholeUrl);
HttpURLConnection con = (HttpURLConnection) object.openConnection();
con.setDoOutput(true);
con.setDoInput(true);
con.setRequestProperty("Content-Type", "application/json");
con.setRequestProperty("Accept", "application/json");
con.setRequestMethod("POST");
JSONObject data = new JSONObject();
JSONObject tel = new JSONObject();
tel.put("nationcode", nationCode);
String phone = phoneNumber;
tel.put("phone", phone);
data.put("type", "0");
data.put("msg", content);
String sig = stringMD5(APPKEY.concat(phone));
data.put("sig", sig);
data.put("tel", tel);
OutputStreamWriter wr = new OutputStreamWriter(con.getOutputStream(), "utf-8");
wr.write(data.toString());
wr.flush();
// 显示 POST 请求返回的内容
StringBuilder sb = new StringBuilder();
int HttpResult = con.getResponseCode();
if (HttpResult == HttpURLConnection.HTTP_OK)
{
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream(), "utf-8"));
String line;

");
}
br.close();
JSONObject reObj = new JSONObject(sb.toString());
String res = (String)reObj.get("result");
if(!"0".equals(res)) {
System.out.println("" + sb.toString());
LOGGER.error("SmsSender::sendMsg" + "-" + phoneNumber + ","+(String)reObj.get("errmsg"));
} else {
