签名算法 sha256

假设:
appId: af37752d8bfc9c23ce9a39e6cf44d135
appSecret: daa153d25c25c3736b474a91aeaa7fa7

代收参数

{
  "appId": "af37752d8bfc9c23ce9a39e6cf44d135",
  "merOrderNo": "4085_12200315",
  "notifyUrl": "https://19fb-15-164-4-252.ngrok-free.app/Payin/Callback/StarPagoPayTHB/4085",
  "currency": "THB",
  "amount": "100",
  "payMethod": "PROMPTPAY",
  "extra": {
    "accountName": "NGUYEN TIEN HUY",
    "accountNo": "123456123456",
    "bankCode": "TMB",
    "email": "StarPago@gmail.com",
    "mobile": "0123445677"
  },
  "return_url": "/",
  "attach": "StarPago",
}

签名准备的字符串

按照key的Unicode进行排序。然后将参数以 key1=value1&key2=value2&key3=value3 的形式拼接, extra 里面的参数同理

amount=100&appId=af37752d8bfc9c23ce9a39e6cf44d135&attach=StarPago&currency=THB&extra=accountName=NGUYEN TIEN HUY&accountNo=123456123456&bankCode=TMB&email=StarPago@gmail.com&mobile=0123445677&merOrderNo=4085_12200315&notifyUrl=https://19fb-15-164-4-252.ngrok-free.app/Payin/Callback/StarPagoPayTHB/4085&payMethod=PROMPTPAY&return_url=/&key=daa153d25c25c3736b474a91aeaa7fa7
