Create a rule service interface for an application to invoke the decision logic by associating the rule to a ruleset of the rule service.
创立 rule service interface 的目标:应用程序通过将规定与规定服务的规定集相关联来调用决策逻辑。
A rule service is an interface or an end point that enables an application to invoke a decision logic.
rule service 能够看成一个接口或者 endpoint,应用程序通过调用 rule service,能够触发 decision logic.
Rule set 是一系列 rule 的汇合,工作于某个特定的场景。
A rule set can be linked to a rule service so that the set of rules in the rule set gets executed when the rule service is deployed.
规定集能够链接到规定服务,以便在部署规定服务时执行规定集内蕴含的所有规定。

从下拉菜单里抉择 vocabulary:
语义是:通过 Employee 信息作为输出,决策出 EquipmentInfo 作为决策后果:

激活整个我的项目:
点击 Deploy 按钮,部署 rule service:
如果部署失败,查看该 Rule Service 应用到的 entity 是否曾经激活,或者是否曾经增加到 Ruleset vocabulary 里:
很显著,这个 Equipment 保护错了,应该批改成 Employee:
SAP API Business Hub 上找到 SAP Business Rules Service:
应用 Rule Execution API for Cloud Foundry 调用 Business Service:
给 wm_businessrules 创立一个新的 service key:
抄下 clientid, clientsecret 和 url 字段,作为 SAP API Business Hub 里保护 environment 的输出值:
生产该 business rule service 的输出 payload:
{ "RuleServiceId": "f27730d10cce4525ae111e647054d8f7", "Vocabulary": [ { "Employee": { "IsFullTimeEmployee": true, "countryofCompany": "USA", "jobTitle": "Engineer II", "company": "2000" } } ]}
