我想过滤我从API获得的JSON集。尝试过的Odata会展开以进行过滤,但无法正常工作。我只想过滤Parameters / Display1值1。
URL:http://localhost/MyApp/DataService/Products/CQ.GetProducts(ProductType=3)$expand=Parameters($filter=Display1 eq 1)
"message": "The type 'Configuration.ProductInfo' is not an entity type. Only entity types support $select and $expand.\r\nParameter name: context"
{
"@odata.context": "http://localhost/MyApp/DataService/$metadata#Collection(Configuration.ProductInfo)",
"value": [
{
"Id": 30102,
"ProductParentId": 30101,
"ProductTypeId": 3,
"Description": "",
"Name": null,
"IsEnabled": true,
"Parameters": [
{
"ProductId": 30102,
"Description": "A2",
"Display1": 1
},
{
"ProductId": 30102,
"Description": "A1",
"Display1": 0
},
{
"ProductId": 30102,
"Description": "A4",
"Display1": 1
},
{
"ProductId": 30102,
"Description": "A3",
"Display1": 0
}
]
},
{
"Id": 30201,
"ProductParentId": 30002,
"ProductTypeId": 3,
"Description": "",
"Name": null,
"IsEnabled": true,
"Parameters": [
{
"ProductId": 30101,
"Description": "A3",
"Display1": 0
},
{
"ProductId": 30101,
"Description": "A3",
"Display1": 0
},
{
"ProductId": 30101,
"Description": "A3",
"Display1": 0
},
{
"ProductId": 30101,
"Description": "A3",
"Display1": 0
}
]
}
]
}
此问题还有其他解决方案吗?
