如何使用javaScript克隆dynamics 365中的自定义实体

var entityId = '<自定义实体的ID>';
var url = '<Dynamics 365 Web API URL>/api/data/v9.0/<自定义实体集合名称>(' + entityId + ')';
var request = new XMLHttpRequest();
request.open("GET", url, true);
request.setRequestHeader("OData-MaxVersion", "4.0");
request.setRequestHeader("OData-Version", "4.0");
request.setRequestHeader("Accept", "application/json");
request.setRequestHeader("Content-Type", "application/json; charset=utf-8");
request.onreadystatechange = function() {
  if (this.readyState === 4 && this.status === 200) {
    var entityData = JSON.parse(this.response);
    // 对获取到的自定义实体数据进行处理
  }
};
request.send();

var clonedEntity = {};
for (var prop in entityData) {
  if (entityData.hasOwnProperty(prop)) {
    clonedEntity[prop] = entityData[prop];
  }
}

var clonedEntityJson = JSON.stringify(clonedEntity);
var createUrl = '<Dynamics 365 Web API URL>/api/data/v9.0/<自定义实体集合名称>';
var createRequest = new XMLHttpRequest();
createRequest.open("POST", createUrl, true);
createRequest.setRequestHeader("OData-MaxVersion", "4.0");
createRequest.setRequestHeader("OData-Version", "4.0");
createRequest.setRequestHeader("Accept", "application/json");
createRequest.setRequestHeader("Content-Type", "application/json; charset=utf-8");
createRequest.onreadystatechange = function() {
  if (this.readyState === 4 && this.status === 204) {
    // 克隆实体保存成功
  }
};
createRequest.send(clonedEntityJson);
