在 Process Visibility Scenario 的 workflow 执行日志里,能找到 BUSINESS_RULES Destination 对应的正确的 endpoint:
显然,下图我配置的 environment 里 request url 不正确,少了 rule 片段:
错误消息:
404 Not Found: Requested route ('bpmruleruntime.cfapps.ap21.hana.ondemand.com') does not exist.
错误的 url:
https://bpmruleruntime.cfapps.ap21.hana.ondemand.com/rules-service/rest/v2/rule-services
正确的 url:
POST https://bpmruleruntime.rule.cfapps.ap21.hana.ondemand.com/rules-service/rest/v2/rule-services
bpmruleruntime.rule.cfapps.ap21.hana.ondemand.com
纠正了 url 之后,错误消息又变了:
{
"error": {
"code": "bpm.rulesruntime.invalidPayload",
"message": "Provide a value for rule service version and revision",
"details": []
}
}
这是因为请求正文格式不正确,或者缺少必填字段造成的。
另一种错误:
Provide a value for rule service version and revision
{
"error": {
"code": "bpm.rulesruntime.internalservererror",
"message": "Error encountered during processing of request",
"details": []
}
}
显然,请求里没有指定 service version 和 revision version 这两个值。
下图是正确的值:
{
"RuleServiceId": "f27730d10cce4525ae111e647054d8f7",
"RuleServiceVersion":"000001000000000000",
"RuleServiceRevision":"JerryFirstVersion",
"Vocabulary": [
{
"Employee": {
... 字段省略,读者需自行填充
}
}
]
}
最后返回 200 状态码,调用成功。
