从Twilio处理json结果

我目前以json列的形式从Twilio中检索语音和短信警报。使用这个tsql代码

SELECT [ReceivedDateTime]
  ,MsgSid = JSON_VALUE(payload, '$.resource_sid')
  ,WebhookURL = JSON_VALUE(payload, '$.webhook.request.url')
  ,ToState = JSON_VALUE(payload, '$.webhook.request.parameters.ToState')
  ,AlertTime = JSON_VALUE(payload, '$.webhook.request.parameters.Timestamp')
  ,Direction = JSON_VALUE(payload, '$.webhook.request.parameters.Direction')
  ,SequenceNumber = JSON_VALUE(payload, '$.webhook.request.parameters.SequenceNumber')
  ,ToNumber = JSON_VALUE(payload, '$.webhook.request.parameters.To')
  ,ToCity = JSON_VALUE(payload, '$.webhook.request.parameters.ToCity')
  ,CallStatus = JSON_VALUE(payload, '$.webhook.request.parameters.CallStatus')
  ,FromNumber = JSON_VALUE(payload, '$.webhook.request.parameters.From')
  ,AccountSid = JSON_VALUE(payload, '$.webhook.request.parameters.AccountSid')
  ,TwilioReason = JSON_VALUE(payload, '$.response.headers.X-Twilio-Reason')
  ,AlertDate = JSON_VALUE(payload, '$.webhook.response.headers.Date')
FROM [dbo].[TwilioAlerts]

我可以查询此文件，直到找到名称中包含破折号的部分。试图引入X-Twilio-Reason，我得到了一个错误：JSON路径的格式不正确。在位置20处发现意外字符“-”。我如何在tsql中引用它

这是我试图查询的json：

有关如何提取“X-Twilio-Reason”的任何答案？

请尝试在名称中带破折号的部分周围添加双引号

,TwilioReason = JSON_VALUE(payload, '$.response.headers."X-Twilio-Reason"')

这不会抛出一个错误，但它只是拉入NULL
