如何验证Laravel中的确切单词? [英] How to validate exact words in Laravel?

问题描述

Laravel中的验证类会验证确切的单词吗?

Does the validation class in Laravel validate exact words?

例如

$rules = [
           "field" => "hello"
         ]

该字段的值必须为"hello".

Where the value of the field must be "hello".

推荐答案

是.我至少知道两种方式.

Yes. I know of at least two ways.

// option one: 'in' takes a comma-separated list of acceptable values
$rules = [
    'field' => 'in:hello',
];

// option two: write a matching regular expression
$rules = [
    'field' => 'regex:^hello$',
];

实际上，我不记得您是否需要在正则表达式中使用^ $分隔符，但是可以很容易地通过尝试找到它. :)

Actually, I don't remember if you need the ^$ delimiters in the regex, but it's easy to find out by trying it. :)
