Run pre-request script on each API request in postman

Question

Can this randomString(length) be reused in another pre-request script instead of having in each API request in postman?

function randomString(length){
  var char ='';
  while(chars.length < length ){
    chars += Math.random().toString(36).substring(2);
  }
  returns chars.substring(0,length);
};

Answer 1

将它放在集合的预脚本中，然后它将在每个请求之前运行。

Answer 2

您可以将该函数存储在环境变量中，然后使用 eval() 函数。
