Postman 中 Pre-request Script 常用 js 脚本

时间：2022-08-28 11:43:01

1. 生成一个MD5或SHA1加密的字符串str_md5，str_sha1

string1 = "123456";

var str_md5= CryptoJS.MD5(string1).toString();  //MD5 加密

var str_sha1= CryptoJS.SHA1(string1).toString(); //SHA1 加密

pm.globals.set("str_md5", str_md5);

2. 生成一个 yyyyMMddHHmm 格式的字符串date_str

var myDate = new Date();  //获取当前时间

var Y = myDate.getFullYear();    // 获取完整的年份(4位)

var M = myDate.getMonth() + 1;       // 获取当前月份(0-11,0代表1月)

    M = M < 10 ? ('0' + M) : M;

var D = myDate.getDate();        // 获取当前日(1-31)

    D = D < 10 ? ('0' + D) : D;

var h = myDate.getHours();       // 获取当前小时数(0-23)

    h=h < 10 ? ('0' + h) : h;

var m = myDate.getMinutes();     // 获取当前分钟数(0-59)

    m = m < 10 ? ('0' + m) : m;

var date_str = Y + M + D + h + m;

pm.globals.set("date_str ", date_str );

另外一种写法是封装了函数，可以直接调用，例如 timestamp ：

function dateFormat(fmt) {

    var nowDate = new Date();

     var o = {

        "M+" : nowDate.getMonth()+1,                 //月份

        "d+" : nowDate.getDate(),                    //日

        "h+" : nowDate.getHours(),                   //小时

        "m+" : nowDate.getMinutes(),                 //分

        "s+" : nowDate.getSeconds(),                 //秒

        "q+" : Math.floor((nowDate.getMonth()+3)/3), //季度

        "S"  : nowDate.getMilliseconds()             //毫秒

    };

    if(/(y+)/.test(fmt)) {

            fmt=fmt.replace(RegExp.$1, (nowDate.getFullYear()+"").substr(4 - RegExp.$1.length));

    }

     for(var k in o) {

        if(new RegExp("("+ k +")").test(fmt)){

             fmt = fmt.replace(RegExp.$1, (RegExp.$1.length==1) ? (o[k]) : (("00"+ o[k]).substr((""+ o[k]).length)));

         }

     }

    return fmt;

}

var timestamp = dateFormat('yyyyMMddhhmmss');

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

3. 生成自增的编号Num

var Num = pm.environment.get("Num");

Num_new = Number(Num)+Number(1);

pm.environment.set("Num", Num_new); 

4. 生成随机数值

//使用 Random 函数获取随机数

const RandomInt = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min;  //取某个数值范围内的随机整数

const getRandomValue = list => list[RandomInt(0, list.length - 1)];     //取某个数组内的随机数值

const random_wishies= ["山河无恙","人月两圆","国泰民安","万事如意","贪吃不胖"];

pm.environment.set("random_wishies",getRandomValue(random_wishies));

5. 获取在某个时间范围内的yyyyMMddHHmm格式的随机时间get_rzsj

StartDate = new Date(2018,0,1);

EndDate = new Date(2018,11,31);

function getRandomDateBetween(StartDate, EndDate)   // 获取指定日期范围内的日期;

{

    var Radomdate = new Date(1958,0,1);

    x = StartDate.getTime();

    y = EndDate.getTime();

    Radomdate.setTime(Math.random()*(y - x + 1) + x);

    return Radomdate;

}

Radomdate = getRandomDateBetween(StartDate,EndDate);

var BY = Radomdate.getFullYear();    // 获取完整的年份(4位)

var BM = Radomdate.getMonth() + 1;   // 获取当前月份(0-11,0代表1月)

    BM = BM < 10 ? ('0' + BM) : BM;

var BD = Radomdate.getDate();        // 获取当前日(1-31)

    BD = BD < 10 ? ('0' + BD) : BD;

var Radomdate_str = BY+ BM + BD ;

pm.globals.set("sjsj", Radomdate_str);

6. 生成随机男女生姓名Name

const FirstName = ['艾','倪','薛','屈','励','池'];

const BoyNames = ['伟','刚','勇','彬','富','顺','信','弘'];

const GirlNames = ['璐','凝','晓','欢','霄','枫','青','婷'];

//使用 getNum 函数获取随机数

const RandomInt = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min;  //取某个数值范围内的随机整数

const getRandomValue = list => list[RandomInt(0, list.length - 1)];     //取某个数组内的随机数值

let EmployeeName = '';  //初始化

let name_sex = '';   //初始化

//判断性别

sex = RandomInt(0,1);

str = BoyNames;//默认使用 BoyNames

if (sex === 0) //如果性别取0时，使用 GirlNames

{

    str = GirlNames;

    name_sex = "2"; //2代表女

}

else

{

    name_sex = "1"; //1代表男

}

pm.globals.set("Employee_sex", name_sex);//获取性别

first = FirstName[Math.floor(Math.random()*FirstName.length-1)];    //随机取一个姓氏

second = str[Math.floor(Math.random()*(str.length-1))];     //随机取str的一个字

hasThird = RandomInt(0, 1);     //使用RandomInt函数判断是否取名字的第二个字

third = "";

if (hasThird == 1)

{

    third = str[Math.floor(Math.random()*(str.length-1))];

}

var ChineseName = first + second + third;

pm.globals.set("Name",ChineseName);

7. 生成随机身份证号码 randomIDcardno

const odd = ['1','3','5','7','9'];  //奇数数组

const even = ['0','2','4','6','8'];     //偶数数组

if (name_sex == '2')

    {

        var num = getRandomValue(even);  //如果性别为女，顺序码第三位取偶数，这里getRandomValue 函数需要引用第5条或第6条的随机数函数，下同

    }

  else

    {

       num = getRandomValue(odd);     //如果性别为男，顺序码第三位取奇数，引用第5条或第6条的随机数函数

    }

function getIDcardno()

{

    const address = ['110000','450501','361100','511323','410701','654322'];  //所有区域代码，这里省略了大部分，需要的可以自己去查下加入

    var areaCode = getRandomValue(address);  //随机获取身份证号码前6位

    var birthday = Radomdate_str;   // 获取6位出生日期

    var sequencecode = Math.floor(Math.random()*10).toString() + Math.floor(Math.random()*10).toString() + num; //生成3位出生顺序码，num 分奇偶数

    var array = (areaCode + birthday + sequencecode).split("");   //split方法分隔17位数字

    var coefficientArray = [ '7','9','10','5','8','4','2','1','6','3','7','9','10','5','8','4','2'];        //加权因子

    var lastNumberArray = [ "1","0","X","9","8","7","6","5","4","3","2"];       //校验码

    var sum = 0;

    for (var i = 0; i < array.length; i++)

       {

            sum = sum + parseInt(array[i])*parseInt(coefficientArray[i]);   //权重求和

       }

    var lastNumber = lastNumberArray[parseInt(sum%11)]; //

    var IDcardno_String = areaCode + birthday + sequencecode + lastNumber;  //

    return IDcardno_String;

}

randomIDcardno = getIDcardno();//获取函数返回值

pm.globals.set("randomIDcardno", randomIDcardno);  //将函数返回值定义给全局变量randomIDcardno

8. 生成随机手机号码 phoneNum

function randomPhoneNum(){

    var Num = '189';

    for(var i=0; i < 8; i++){

        Num += Math.floor(Math.random() * 10);

    }

    return Num;

}

var str_phone = randomPhoneNum();

pm.globals.set("phoneNum", str_phone);

9. 生成一个4位字母数字混合的字符串

pm.globals.set("random_code", ("0000" + (Math.random()*Math.pow(36,4) << 0).toString(36)).slice(-4));

10. 生成当前的时间戳

pm.globals.set("unixtime_now", Math.round(new Date().getTime()/1000));
