Office365报告REST API - “查询无效。”

Question

为什么我能够使用以下请求查询Office365的Reporting API：

https://reports.office365.com/ecp/reportingwebservice/reporting.svc/MessageTrace?$select=Subject,SenderAddress,RecipientAddress,Status,Received,Received&$filter=SenderAddress eq 'foo@bar.com' and RecipientAddress eq 'bar@foo.com' and StartDate eq datetime'2016-10-01T00:00:00' and EndDate eq datetime'2016-10-03T00:00:00'

但是当我修改它以过滤主题时 ，它会返回一个错误：

https://reports.office365.com/ecp/reportingwebservice/reporting.svc/MessageTrace?$select=Subject,SenderAddress,RecipientAddress,Status,Received,Received&$filter=SenderAddress eq 'foo@bar.com' and RecipientAddress eq 'bar@foo.com' and StartDate eq datetime'2016-10-01T00:00:00' and EndDate eq datetime'2016-10-03T00:00:00' and Subject eq 'Test'

{“odata.error”：{“code”：“InvalidQueryException”，“message”：{“lang”：“”，“value”：“查询无效。” }}}

Answer 1

尝试类似的东西

startswith(Subject,'Test')
