在發送請求的時候，我們需要用到隨機數，例如：請求的參數是隨機的郵箱，隨機的字符，隨機的圖片等...那這種情況，我們如何做到隨機生成值呢？哈哈哈哈，postman內置了一些隨機變量。
接下來分爲兩部分，第一部分：隨機變量有哪些。第二部分：如何使用。
第一部分：官方文檔：https://learning.getpostman.com/docs/postman/variables-and-environments/variables-list/
針對裏面隨機變量的中文解釋（哈哈哈哈哈....）以下文檔從簡書中某位大佬中摘取。

function getRadomNum(capacity){
//chars中是你要想要的字符的數組
var chars = ['0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'];
var res = "";
for(var i = 0; i < capacity ; i ++) {
var id = Math.ceil(Math.random()*chars.length-1);
res += chars[id];
}
return res;
}
//隨機的1-10位數
