// 以下是请求
String app_key = "123123";
String timestamp = "2021-7-20 09:28:34";
// 拼接 https://xxxxx.com/aaa/bbb?xxx=xxx&xxx=xxx
// 因为时间戳 timestamp 中有空格，所以使用URLEncoder.encode转码
StringBuffer urlBuffer = new StringBuffer();

.append("app_key=").append(appkey).append("&")
.append("timestamp=")
.append(URLEncoder.encode(timestamp,"utf-8"));
String strResult = SSLClient.doGet(urlBuffer.toString());
POST请求：
String url = "https://openapi.com";
Strng method = "/token/create";
// 以下是请求参数
String app_key = "123123";
String timestamp = "2021-7-20 09:36:43";
