Interactive Format Description

1.1 Encoding Format

Unified use of UTF-8 encoding during interaction


1.2 Request Body

The request body format is a UTF-8 encoded JSON format string, such as:



1.3 Request Header

User-Agent: openApi

Content-Type: application/json; charset=utf-8

Accept-encoding: gzip,deflate

Time-stamp: 1437528688233

Data-signature: BF706E6AC693BA3B1BABD32E6713431D

Time-stamp: Timestamp, which is the total number of milliseconds since January 1, 1970 (08:00:00 GMT) to the current time. It is also known as Unix Timestamp (Unix Timestamp)

Data-signature: the signature generated by the request body through the md5 algorithm


Java generation method

String data-signature = encryptToMd5String(JSONStr, appKey)


String encryptToMd5String(String content,String appKey)


     Return encryptToMd5String(

     StringUtils.trim (appKey)+StringUtils.trim(content));



String encryptToMd5String(String content)


     String md5String = null;

     MessageDigest md = MessageDigest.getInstance("md5");


     md5String = parseByte2HexString(md.digest());

     Return md5String;



String parseByte2HexString(byte buf[])


     StringBuffer stringBuffer = new StringBuffer();

     For (int i = 0; i < buf.length; i++)


          String hex = Integer.toHexString(buf[i] & 0xFF);

          If (hex.length() == 1) {hex = '0' + hex;}



     Return stringBuffer.toString();



PHP generation method

$signature = strtoupper(md5($appKey.$jsonData));


C# generation mode

FormsAuthentication.HashPasswordForStoringInConfigFile(appkey+jsonData, "MD5")



1.4 Response Body

The response body format is a UTF-8 encoded JSON format string, such as:



1.5 Response Header

Data-signature: BF706E6AC693BA3B1BABD32E6713431D

Content-Type: application/json;charset=UTF-8

The way of generate Data-signature is the same way as the data-signature of the request header to ensure that the data is returned from the POS system.
