postman签名算法（将请求体参入签名算法计算）

let timestamp = (new Date()).getTime().toString(); 

timestamp = timestamp.substr(0,13);

//设置集合的全局变量

pm.collectionVariables.set("timestamp", timestamp);

var appkey='XXXXXXX';

pm.collectionVariables.set("appkey",appkey);

function generateUUID() {

  return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {

    var r = Math.random() * 16 | 0,

        v = c === 'x' ? r : (r & 0x3 | 0x8);

    return v.toString(16);

  });

}

console.log(generateUUID());

var nonce = generateUUID();

pm.collectionVariables.set("nonce",generateUUID());

const requestBody = pm.request.body.raw;//获取请求体

const newRequestBody = requestBody.replace(/\s+/g, '');//将请求体的空格和换行删除

var tianti='XXXXXXX';

var signStr ='appkey'+appkey +'nonce'+nonce+'timestamp'+timestamp+newRequestBody+tiantian;

console.log("signStr :"+signStr);

//md5加密

var signature=CryptoJS.MD5(signStr).toString().toUpperCase();

console.log("sign:"+signature);

pm.collectionVariables.set("sign", signature);



中台验签算法
 

let timestamp = (new Date()).getTime().toString(); 
timestamp = timestamp.substr(0,13);
//设置集合的全局变量
pm.collectionVariables.set("timestamp", timestamp);

var appkey='XXXXXXXXX';
pm.collectionVariables.set("appkey",appkey);



function generateUUID() {
  return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
    var r = Math.random() * 16 | 0,
        v = c === 'x' ? r : (r & 0x3 | 0x8);
    return v.toString(16);
  });
}

console.log(generateUUID());
var nonce = generateUUID();

pm.collectionVariables.set("nonce",generateUUID());

const requestBody = pm.request.body.raw;//获取请求体
const newRequestBody = requestBody.replace(/\s+/g, '');//将请求体的空格和换行删除

var secret='XXXXXXXX';
var signStr ='appkey'+appkey +'nonce'+nonce+'timestamp'+timestamp+requestBody+secret;
console.log("signStr :"+signStr);


//md5加密

var signature=CryptoJS.MD5(signStr).toString().toUpperCase();
console.log("sign:"+signature);
console.log("signStr :"+signStr);
pm.collectionVariables.set("sign", signature);
