在发送请求的时候，我们需要用到随机数，例如：请求的参数是随机的邮箱，随机的字符，随机的图片等...那这种情况，我们如何做到随机生成值呢？哈哈哈哈，postman内置了一些随机变量。
接下来分为两部分，第一部分：随机变量有哪些。第二部分：如何使用。
第一部分：官方文档：https://learning.getpostman.com/docs/postman/variables-and-environments/variables-list/
针对里面随机变量的中文解释（哈哈哈哈哈....）以下文档从简书中某位大佬中摘取。

//chars中是你要想要的字符的数组
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;
}
//随机的1-10位数
var name = getRadomNum( Math.ceil(Math.random()*10))
第二部分：使用
在请求时，直接传{{$randomEmail}} 注意：一定不能有空格，错误示范：{{$ randomEmail}}
备注：如果使用动态变量，每次请求都会生成一个新的。
例如：你请求时邮箱是随机邮箱，然后将邮箱设置为全局变量后，下次取邮箱，仍然是一个新的随机邮箱。取不到上述的邮箱。
