Realex付款,无法处理响应。Net

我试图实现一个hpp完全重定向到realex payment,我有两个控制器,一个将请求发送到realex payment server,另一个将响应发送回。我得到了json的响应

{"RESULT":"00","AUTHCODE":"12345","MESSAGE":"[ test system ] AUTHORISED","PASREF":"15441812060166886","AVSPOSTCODERESULT":"M","AVSADDRESSRESULT":"M","CVNRESULT":"M","ACCOUNT":"internet","MERCHANT_ID":"MyID","ORDER_ID":"UYCRWpJtlE-B1n62SE7EKg","TIMESTAMP":"20181207111253","AMOUNT":"199","MERCHANT_RESPONSE_URL":"URL to my webcontroller","pas_uuid":"b3cfa79e-2b60-4f2a-9dad-cfa897f17189","SHA1HASH":"c193e099da587b28810775f388d15c2f88fd637c","BATCHID":"601099"}

我遇到的问题是,这个json显示在具有以下URL的页面中。 https://pay.sandbox.realexpayments.com/card.html?guid=b3cfa79e-2b60-4f2a-9dad-cfa897f17189 但我想从这个json中提取订单id、交易id和金额,并以某种形式显示在out company页面中,告知用户根据结果成功或拒绝付款。
