url地址及請求引數是已知的：

//依據使用者openId判斷使用者以前是否已登入過,如未登入，則新增到資料庫
logger.info("{}---{}", accessToken, openId);
JSONObject userInfo = weChatAuthService.getUserInfo(accessToken, openId);
//呼叫後臺介面
String checkurl="V1/OrgManager/getUsers?";
AuthInfo authInfo = new AuthInfo("", "", "", "");
String authInfoJson = JSON.toJSONString
 
(authInfo);
String queryCase = "filter=&&name="+openId.trim()+"&&authInfo="+authInfoJson+"&&pageable=false"+"&&pageSize=2"+"&&pageNum=0"+"&&sortDesc=name:desc"+"&&orgId=e9292051-2ede-11e7-8c78-c85b767a1aee";
JSONObject jsonResult= DubboService.invokeService
 
(logger,checkurl,queryCase);

if(jsonResult.get("isOk")==true)
{
    Map<String,JSONArray> nickname = new HashMap<String,JSONArray>();
    Map<String,JSONArray> headimgurl = new HashMap<String,JSONArray>();
    model.addAttribute("nickname",nickname);
    model.addAttribute("headimgurl"
 
,headimgurl);
} else {
    String createurl = " V1/UserManager/createUser?";
    String UserCase = "filter=&&name="+openId.trim()+"&&authInfo="+authInfoJson+"&&pageable=false"+"&&pageSize=2"+"&&pageNum=0"+"&&sortDesc=name:desc"+"&&orgId=e9292051-2ede-11e7-8c78-c85b767a1aee";
    JSONObject jsonUser= DubboService.invokeService(logger,createurl,UserCase);

}

以上就部分程式碼：這裡DubboService是暴露給你的介面；checkurl就是介面文件裡面的url；UserCase是查詢條件，這是訪問資料庫的介面認證。如果訪問成功將部分引數傳給前端，如果訪問不成功將得到引數寫入資料庫

以下是DubboService方法：
