按日期筛选的 OData 抛出 "The query specified in the URI is not valid. An identifier was expected at position 62"

Question

我正在使用 OData 从我的 SQL Db 查询数据，我正在尝试使用日期值过滤数据。请参阅下面的查询：

http://localhost:4409/OrderMaintenance?$filter=DocType%20eq%205%20and%20DocState%20in%20(0,1,2,3,4,5,6,7)%20and%20InvDate%20eq%202022/02/21

此查询中只有日期是问题，因为当我删除日期过滤器时，查询工作正常。

InvDate 的类型为：

orderDateFilter: Date = new Date();

然后我将日期格式化为：

this.orderDateFilter.toLocaleDateString()

returns 日期为：

2022/02/21

但是我收到以下错误

"The query specified in the URI is not valid. An identifier was expected at position 62."

Answer 1

尝试使用破折号而不是反斜杠来格式化 odata 日期过滤器： 2022-02-21 而不是 2022/02/21。 您可能还需要添加时间部分。这是一个时间为午夜 2022-02-21T00:00:00Z 的示例。

Answer 2

我用过：

this.orderDateFilter.toISOString()

将我的日期转换为：

2022-02-22T09:17:24.822Z

但是我在查询时遇到了问题，因为我只想检查不包括时间的日期。所以我改为使用：

this.datepipe.transform(this.orderDateFilter.toLocaleDateString(),'yyyy-MM-dd')

效果很好！
