### Question:
JssdkUtils { public static Map<String, String> sign (final String jsapiTicket) { return sign(jsapiTicket, ""); } private  JssdkUtils(); static Map<String, String> sign(final String jsapiTicket); static Map<String, String> sign(final String jsapiTicket, final String url); static String getAccessToken(final String appId, final String appSecret); static String getJsapiTicket(final String appId, final String appSecret); static String getJsapiTicket(final String accessToken);  }### Answer:
@Test public void testSign () { final String jsapiTicket = JssdkUtils.getJsapiTicket(appId, appSecret); final Map<String, String> map = JssdkUtils.sign(jsapiTicket, url); for (Map.Entry<String, String> entry : map.entrySet()) { LOG.info(entry.getKey() + ":" + entry.getValue()); } }
