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));
