在SQL Server中发出HTTP请求时，如何传入OAuth2.0令牌？

sp_configure 'show advanced options', 1;
RECONFIGURE;
sp_configure 'Ad Hoc Distributed Queries', 1;
RECONFIGURE;

DECLARE @url NVARCHAR(200) = 'https://example.com/api/endpoint';
DECLARE @token NVARCHAR(200) = 'your_oauth_token';

DECLARE @headers NVARCHAR(4000) = 'Authorization: Bearer ' + @token;

DECLARE @response NVARCHAR(MAX);

EXEC sp_OACreate 'MSXML2.ServerXMLHTTP', @response OUT;
EXEC sp_OAMethod @response, 'Open', NULL, 'GET', @url, 'false';
EXEC sp_OAMethod @response, 'setRequestHeader', NULL, 'Content-Type', 'application/json';
EXEC sp_OAMethod @response, 'setRequestHeader', NULL, 'Authorization', @headers;
EXEC sp_OAMethod @response, 'send';

DECLARE @result XML;
EXEC sp_OAMethod @response, 'responseXML', @result OUTPUT;

SELECT @result;
