postman pre-request 编写签名请求脚本

设置body raw内容为{{body}}

let body = {"userCode":"XXXXX"};
const appid='XXXXXX';
const appkey='XXXXXXX';

body.appid = appid;
body.ts = parseInt(Date.now()/1000);
let keys = Object.keys(body);
keys.sort();
let str = '';
for (let k of keys) {
    if(Array.isArray(keys[k])){

    }else{
        str += k + '=' + body[k] + '&';
    }
} 
str = str.slice(0, str.length -1) + appkey;
body.signature = CryptoJS.MD5(str).toString();
console.log(body)
pm.environment.set('body',JSON.stringify(body));

// const postRequest = {
//   url: request.url,
//   method: 'POST',
//   header: request.headers,
//   body: {
//     mode: 'raw',
//     raw: JSON.stringify(body)
//   }
// };

// pm.sendRequest(postRequest, (error, response) => {
//     console.log(error ? error : response.json());
// });
