SQL Bing XML数据-@Responsetext始终为空

我创建了一个从Bing的xml数据中检索TravelDistance的过程，但是@ResponseText总是空的。我可以让它与谷歌合作，但不能与必应合作。我已经从Bing的API网站上硬编码了这个示例，我可以看到XML和@ServiceUrl，但是

Exec sp_OAMethod@Object，'responseText'，@responseText输出

为@Object提供一个值，为@ResponseText仅提供NULL

`    Declare @Object as Int;
Declare @ResponseText as nvarchar(max);
Declare @serviceUrl as varchar(max)

  --set @serviceUrl = 'http://maps.googleapis.com/maps/api/distancematrix/xml?origins=' +@ToAddress+@ToCity+@ToState+@ToPostCode+
  -- '&destinations=' +@FromAddress+@FromCity+@FromState+ @FromPostCode +'&mode=driving&language=en-EN&units=imperial;'
  set @serviceUrl = 'https://dev.virtualearth.net/REST/v1/Routes/Truck?wp.0=590%20Crane%20Ave%2C%20Pittsburgh%2C%20PA&wp.1=600%20Forbes%20Ave%2C%20Pittsburgh%2C%20PA&vehicleHazardousMaterials=Flammable&output=xml&key=XXXXXXXXXXXXXXXX'
Exec sp_OACreate 'MSXML2.XMLHTTP', @Object OUT;

Exec sp_OAMethod @Object, 'open', NULL, 'get',
                @serviceUrl, --Your Web Service Url (invoked)
                 'false'

Exec sp_OAMethod @Object, 'send'
Exec sp_OAMethod @Object, 'responseText', @ResponseText OUTPUT
declare @result table(data text)


Declare @Response as XML
SELECT @Response response, @ResponseText responsetext,@serviceUrl serviceurl
Select @ResponseText as XMLList

SET @Response = CAST(@ResponseText AS XML);

  Declare @Status as varchar(20)
   Declare @Distance as varchar(20)
   Declare @Time as varchar(20)

--  
set @Status= @Response.value('(Response/ResourceSets/ResourceSet/Resources/Route/BoundingBox/TravelDistance)[1]', 'varchar(20)') 
  print @Status
  if(@Status='ZERO_RESULTS')

   Begin

                     set @Distance=@Status
   End
   else

   Begin
--   set @Distance=@Response.value('(DistanceMatrixResponse/row/element/distance/text)[1]', 'varchar(20)') 
    set @Distance=@Response.value('(Response/ResourceSets/ResourceSet/Resources/Route/BoundingBox/TravelDistance)[1]','varchar(20)')
 --     set @Time=@Response.value('(DistanceMatrixResponse/row/element/duration/text)[1]', 'varchar(20)') 
   End
--  Select @Response.value('(DistanceMatrixResponse/row/element/distance/text)[1]', 'varchar(10)') as Distance 
--  select (cast(replace(@Distance,' km','') as numeric)/2) + ((cast(replace(@Distance,' km','') as numeric)/2)/4) as Distance, @Time as Time
    select @Distance as Distance`

我遗漏了什么？

回复有多大

sp_-OAMethod

似乎对其可以处理的内容有大小限制。大小过大。我如何绕过限制？
