Signature algorithm

The general steps for signature generation are as follows:

The first step is to set all parameters as a set M, sort the parameters according to the ASCII code of the parameter name from small to large (lexicographical order), and use the URL key-value pair format (ie. key1=value1&key2=value2…) spliced into a stringA

The second step is to append the merchant API key to the final splicing of stringA to obtain the stringSignTemp string, and perform MD5 calculation on stringSignTemp, and then convert all characters of the string to uppercase to obtain the sign value

stringSignTemp="amount=&code=&merchantid=&notify&orderid=&key=" sign=MD5(stringSignTemp).toUpperCase()
