首先我们得有一个可以正常工作的Restful API：

然后在Cloud for Customer的Cloud Application Studio里创建Restful API的模型，把第一步可以正常工作的Restful API url填进模型里去：

然后在ABSL里使用如下代码进行消费：

import ABSL;if( this.OutboundDeliveryID.IsInitial() == false){    raise already_delivered.Create("E");    return;}var HttpMethod = "GET";var HttpResource = "";                            // not requiredvar ContentType = "";                             // not requiredvar Body = "";                                    // not requiredvar HeaderParameter : collectionof NameAndValue;  // not requiredvar URLParameter    : collectionof NameAndValue;var URLParameterEntry : NameAndValue;URLParameterEntry.Name  = "SoID";URLParameterEntry.Value = this.ID.content;URLParameter.Add(URLParameterEntry);var response = WebServiceUtilities.ExecuteRESTService("JerryExternalService", "JerryExternal", HttpMethod, HttpResource,URLParameter, HeaderParameter,ContentType, Body);this.OutboundDeliveryID = response.Content;raise delivery_message.Create("S", this.OutboundDeliveryID);
