生成随机字符串的脚本不起作用

本文介绍了生成随机字符串的脚本不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试生成带有空格的随机字符串，但它不起作用:

I'm trying to generate random string with white spaces but it is not working :

/rs {
  %i=1
  %r=$rand(1,50)
  %s=$rand(a,z)
  while(%i <= %r) {
    %i=%i+1
    %s=%s $+ $rand(a,z)
    if(1 == rand(1,4) %s=%s $+ $chr(32)
  }
  echo %s
}

WHILE(%I Unknown command

有什么想法吗?

推荐答案

您遇到了一些问题，这些只是其中的一小部分.

You had some issues, those are just few of them.

空格:当涉及到空格时，mSL 语句是有意义的，那些你应该在 while (expression), if (expression) 甚至 %i = 1 和 %r = $rand(1,50) etc'

Spaces: mSL statements are sensebile when it concerns to spaces, those you should put spaces between the while (expression), if (expression) and even %i = 1 and %r = $rand(1,50) etc'

括号:您可能忘记了空间生成器条件下的小括号.应该是 if (1 == rand(1,4)) %s=%s $+ $chr(32)

Parenthesis: You probably have forgotten the little parenthesis at the space generator condition. Should be if (1 == rand(1,4)) %s=%s $+ $chr(32)

$ 符号:您还忘记在此标识符之前放置此符号 rand(1,4) 应该是 $rand(1,4)

$ sign: You also forgotten to put this sign before this identifier rand(1,4) should be $rand(1,4)

固定片段:

rs {
  %i = 1
  %r = $rand(1,50)
  %s = $rand(a,z)
  while (%i <= %r) {
    %i = %i + 1
    %s = %s $+ $rand(a,z)
    if (1 == $rand(1,4)) %s = %s $chr(32)

  }
  echo -ag %s
}

我冒昧地设计了一些不同的代码，现在您可以将其用作 $identifier 而不是别名，这将为您提供更大的灵活性和可用性.

I took the liberty of designing the code a bit different, now you can use it as $identifier instead of an alias, which will give you further flexibility and usability.

用法:

echo -ag $rs(默认长度为 50 个字符)
echo -ag $rs(20)(长度为 20 个字符的随机字符串)
set %myName $rs(15)(将输出的随机字符串保存到一个常量变量中)

echo -ag $rs (default will be 50 characters long)
echo -ag $rs(20) (random string with length of 20 charcathers)
set %myName $rs(15) (will save the output random string into a constant variable)

片段:

rs {
  if (!$1) {
    tokenize 32 50
  }

  var %randString
  var %randStringLength = $rand(1, $1)
  var %i = 1
  while (%i <= %randStringLength) {
    %randString = %randString $+ $rand(a, z)
    if ($rand(1, 4) == 1) {
      %randString = %randString $chr(32)
    }
    inc %i
  }
  return %randString
}
