请求示例
查询表达式up在时间点1630124012的计算结果。
https://{EndPoint}/v1/{project_id}/aom/api/v1/query?query=up&time=1630124012
响应示例
状态码: 200
OK 请求响应成功。
{ "status" : "success", "data" : { "resultType" : "vector", "result" : [ ] } }
状态码: 400
BadRequest 非法请求。建议直接修改该请求,不要重试该请求。
{ "status" : "error", "errorType" : "bad_param", "error" : "param is invalid." }
状态码: 403
Forbidden 请求被拒绝访问。返回该状态码,表明请求能够到达服务端,且服务端能够理解用户请求,但是拒绝做更多的事情,因为该请求被设置为拒绝访问,建议直接修改该请求,不要重试该请求。
{ "status" : "error", "errorType" : "auth", "error" : "auth project_id not pass." }
状态码: 422
Unprocessable 表达式无法执行。
{ "status" : "error", "errorType" : "excution", "error" : "expression can't be executed." }
状态码: 503
ServiceUnavailable 被请求的服务无效。建议直接修改该请求,不要重试该请求。
{ "status" : "error", "errorType" : "timeout", "error" : "query timed out in query execution." }
