## 3.Description of verifying the signature
```
1.For a POST request message sent to the AllPay system, in which all incoming parameters (except signature parameters) according to the field name of ASCII smallest sequence (dictionary), using the format of the URL key/value pair (key1 = value1 & key2 = value2... ) spliced into a string String1.
2.At the end of String1, the signature Key (assigned at AllPay upon access) agreed by both parties is spliced directly (no need to connect with "&"), resulting in a stringSignTemp string, and an encryption on stringSignTemp to get the value of signature.
3.Sample signature string: acqID=99020344&backURL=https://www.allpayx.com&charSet=UTF-8&detailInfo=W3siZ29vZHNfbmFtZSI6IuiLueaenCIsInF1YW50aXR5IjoiMyJ9LHsiZ29vZHNfbmFtZSI6IuapmOWtkCIsInF1YW50aXR5IjoiNyJ9XQ==&frontURL=https://www.baidu.com&goodsInfo=apple&merID=000000000000015&merReserve=iPhone&orderAmount=0.01&orderCurrency=USD&orderNum=20190104022800&paymentSchema=AP&signType=MD5&transTime=20190104022800&transType=PURC&version=VER0000000052f2c77e3718c47cfb47a89a6fbc9d361
