2.验签公钥：

【MIIBIjANBgktf9owIDAQAB】

3.从报文取出签名值sign：

【zs+snU7B3l4Cnec/JWBcXWkFUNWrW1ttEeMZI4X2mtuSNQ9LL9Mri3b6QK0xTc/KMs/Cafk0Ln7iRKQZfnuBvvuaOwVxSgjuWT0ygGktDok0HITE2wKeT8j4SNX4ScIGHLqHXkMojXIZxE6bsfD9kjUb356aFItinf3vURu3FuPSkbJR1KZXDm41hz2rQ9o6Sc3Xs2cr7AbCSVgyGjv5c6G6OiqaXcdgM+FxHtxkhfqB/3awRjXMGmLmWr2m5VyFIfNMOuNCdRN7fNkUBIX3h35KI6av/x6BDYKwTW2zrJHVy91C0h3mrVoDNuRrJ4fPMW2ZH88j7Q3exmPTP0gqMA==】

二、组成待验签串：

1.剔除空值参数：

2.剔除sign、sign_type参数：

【gmt_create=2020-03-25 10:59:32&charset=utf-8&gmt_payment=2020-03-25 10:59:38&notify_time=2020-03-25 10:59:38&subject=仙玉小袋&buyer_id=2088002582656381&body=仙玉小袋&invoice_amount=0.01&version=1.0&notify_id=2020032500222105938056380529774436&fund_bill_list=[{"amount":"0.01","fundChannel":"PCREDIT"}]&notify_type=trade_status_sync&out_trade_no=TEST171&total_amount=0.01&trade_status=TRADE_SUCCESS&trade_no=2020032522001456380542497258&auth_app_id=2021001144680325&receipt_amount=0.01&point_amount=0.00&buyer_pay_amount=0.01&app_id=2021001144680325&seller_id=2088031940831575】

3、排序：

【app_id=2021001144680325&auth_app_id=2021001144680325&body=仙玉小袋&buyer_id=2088002582656381&buyer_pay_amount=0.01&charset=utf-8&fund_bill_list=[{"amount":"0.01","fundChannel":"PCREDIT"}]&gmt_create=2020-03-25 10:59:32&gmt_payment=2020-03-25 10:59:38&invoice_amount=0.01&notify_id=2020032500222105938056380529774436&notify_time=2020-03-25 10:59:38&notify_type=trade_status_sync&out_trade_no=TEST171&point_amount=0.00&receipt_amount=0.01&seller_id=2088031940831575&subject=仙玉小袋&total_amount=0.01&trade_no=2020032522001456380542497258&trade_status=TRADE_SUCCESS&version=1.0】
