本文介绍如何使用Postman进行环境变量设置及生成请求签名，包括时间戳、UUID生成、字符串日期转换为毫秒级时间戳等操作，并通过MD5加密确保数据安全性。

//设置timestamp
var timestamp = Math.round(new Date().getTime())
pm.environment.set("timestamp",timestamp );
var dspId = pm.environment.get("dspId");
var secret_key = pm.environment.get("secret_key");
//requestId 生成uuid
function guid() {
    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);
    });
}
var requestId = guid();
pm.environment.set("requestId", requestId);
var signStr = 'dspId='+dspId+'&'+'requestId='+requestId+'&'+'timestamp='+timestamp+secret_key;
var sign = CryptoJS.MD5(signStr).toString();
pm.environment.set("sign", sign);

//将字符串日期时间转为毫秒级时间戳
var bodyData = pm.request.body['raw'];
bodyDataJson = JSON.parse(bodyData)
var beginDate = bodyDataJson.beginDate;
var endDate = bodyDataJson.endDate;
var beginDateStr = new Date(beginDate).getTime()-8*60*60*1000
var endDateStr = new Date(endDate).getTime()-8*60*60*1000
bodyDataJson.beginDate=beginDateStr;
bodyDataJson.endDate = endDateStr;
pm.request.body.raw = JSON.stringify(bodyDataJson);
var hostUrl = pm.environment.get('env_host');
//字符串格式化占位符
String.prototype.signMix= function() {
	if(arguments.length === 0) return this;
	var param = arguments[0], str= this;
	if(typeof(param) === 'object') {
		for(var key in param)
			str = str.replace(new RegExp("\\{" + key + "\\}", "g"), param[key]);
		return str;
	} else {
		for(var i = 0; i < arguments.length; i++)
			str = str.replace(new RegExp("\\{" + i + "\\}", "g"), arguments[i]);
		return str;
	}
}
// 准备请求头和请求数据在前置脚本中发起本请求 json格式发起请求
var headersfact = '{"requestId":"{0}","Content-Type":"application/json","dspId":"{1}","timestamp":"{2}","sign":"{3}"}'.signMix(requestId,dspId,timestamp,sign);
const requestTestFact = {
    url:hostUrl+'/XX/XX/XX',
    method:'POST',
    header: JSON.parse(headersfact),
    body:{
        mode:'raw',
        raw:JSON.stringify(bodyDataJson)
    }
};
console.log(requestTestFact);
pm.sendRequest(requestTestFact, function (err, response) {
    console.log(response.json());
});
