Sign execution process
merchant side
Before the merchant requests the EPAY server, encapsulate the request parameter API_KEY, generate a Sign signature according to the agreed algorithm, and then put it into the request body together with the parameters and send it to the EPAY server;
EPAY server
The EPAY server generates the corresponding Sign signature from the received request data and compares it with the Sign signature from the merchant. If the two Sign signatures are consistent. Access to EPAY server data is allowed through verification, otherwise access is prohibited.
[warning] Note:
The merchant side needs to save the API_KEY. If the API_KEY is lost or unsafe, please reapply to generate a new API_KEY.
Sign generation algorithm
Step 1: encapsulate the request parameters into json object types and remove empty and null values.
Step 2: the json object is converted into a json string by ASCII sorting according to the parameter name (case-sensitive).
Step 3: it is to convert the json string into the queryString string, that is, key1 = value1 & key2 = value2 & key3 ={subKey1 = sValue1,subKey2 = sValue2}, traverse the json object, and convert the key-value data into the queryString string.
Step 4: Split the string in the queryString format with key ={API_KEY}. For example, if API_KEY = 3 A4BC4A4000CF1B5FFA9E351E6C15rfs3, the string changes to key1 = value1 & key2 = value2 & key3 ={subKey1 = sValue1,subKey2 = sValue2}*& key = 3 A4BC4A4000CF1B5FFA9E351E6C15rfs3 *
Step 4: it is to perform sha256 operation on the spliced string, and then convert it to uppercase to obtain the sign value for api request.
