.net 如何对odata端点执行搜索操作

CRM 2016公开了odata/web api，并且具有开箱即用的特性

我正在尝试执行以下请求：

https://mycrmorg.com/api/data/v8.1/Search(AppointmentRequest=@request)?@request={"ServiceId":"0640dd7b-984f-e711-9425-00155dc0d345","AnchorOffset":1,"UserTimeZoneCode":1,"RecurrenceDuration":0,"RecurrenceTimeZoneCode":1,"RequiredResources":{"ResourceId":"2031105f-ec0d-e711-9417-00155d835de9"},"SearchWindowStart":"1754-01-01T00:00:00Z","SearchWindowEnd":"9999-12-30T23:59:59Z","SearchRecurrenceStart":null,"Duration":1,"Constraints":[],"Objectives":[],"NumberOfResults":1,"Sites":[]}

更漂亮的json版本：

{
   "ServiceId":"0640dd7b-984f-e711-9425-00155dc0d345",
   "AnchorOffset":1,
   "UserTimeZoneCode":1,
   "RecurrenceDuration":0,
   "RecurrenceTimeZoneCode":1,
   "RequiredResources":{
      "ResourceId":"2031105f-ec0d-e711-9417-00155d835de9"
   },
   "SearchWindowStart":"1754-01-01T00:00:00Z",
   "SearchWindowEnd":"9999-12-30T23:59:59Z",
   "SearchRecurrenceStart":null,
   "Duration":1,
   "Constraints":[

   ],
   "Objectives":[

   ],
   "NumberOfResults":1,
   "Sites":[

   ]
}

我得到的例外是：

我认为我对RequiredResources的编码可能有问题。我做错了什么？我如何将此请求发送给CRM？

我认为问题可能是您将

RequiredResources

用作对象而不是集合，请尝试将其更改为

"RequiredResources": [{
   "ResourceId":"2031105f-ec0d-e711-9417-00155d835de9"
}],

完全JSON

{
   "ServiceId":"0640dd7b-984f-e711-9425-00155dc0d345",
   "AnchorOffset":1,
   "UserTimeZoneCode":1,
   "RecurrenceDuration":0,
   "RecurrenceTimeZoneCode":1,
   "RequiredResources": [{
      "ResourceId":"2031105f-ec0d-e711-9417-00155d835de9"
   }],
   "SearchWindowStart":"1754-01-01T00:00:00Z",
   "SearchWindowEnd":"9999-12-30T23:59:59Z",
   "SearchRecurrenceStart":null,
   "Duration":1,
   "Constraints":[

   ],
   "Objectives":[

   ],
   "NumberOfResults":1,
   "Sites":[

   ]
}

所需资源 集合（RequiredResource ComplexType）

取自

错误消息实际上告诉您，解析器预期的是[而不是{symbol/token]
