呼叫如下

post請求

String mobileString = "{\"openId\":\""+openId+"\"}";
JSONObject parse = JSONObject.parseObject(sendPostHttps(url, mobileString));
String loginToken = parse.getJSONObject("data").getString("result");
return loginToken;


如果要是get請求   沒有引數 

JSONObject parse = JSONObject.parseObject(sendPostHttps(url,null));
String loginToken = parse.getJSONObject("data").getString("result");
return loginToken;
