OpenIDM通过自定义终结点更新用户属性

Question

我正尝试在OpenIDM中开发一个自定义js端点，在该端点中，我使用在脚本中生成的两个属性(otpexpiry和otpvalue)更新搜索到的用户。

我在openidm/conf/endpoint-otp.json中添加了一个json conf来链接：

{
 "context" : "endpoint/otp/*",
 "type" : "text/javascript",
 "file" : "script/otp.js"
}

这是我的脚本openidm/script/otp.js

(function() {
 if(request.method === "update") {
  var five_minutes = 5 * 60 * 1000;
  var timestamp = new Date().getTime();
  var otpexpiry = timestamp + five_minutes;
  var otpvalue = Math.floor(Math.random() * 9999);


  /* Not sure of this code below I have to update the user searched with " otpdate : otpexpiry " and "otp : otpvalue "*/
  var u = request.value;
  var id = "managed/user/" + u._id;
  if (id != null) {
    openidm['update']( ... );
  }

  return {
       method: "update",
       resourceName: request.resourcePath,
       revision: request.revision,
       parameters: request.additionalParameters,
       patch: request.patchpperations,
       context: context.current
       };
  } else {
       throw { code: 500, message: "Unknown request type " + request.method};
  }
})();

如何更新搜索到的用户的两个变量？
