Perl哈希键的合法值 [英] Legal values for Perl hash key

问题描述

我正在尝试重用我们内部提供的库函数，但是由于输入中的新变体，导致某些东西无法正常工作并引发错误.

I'm trying to reuse a library function we have in house, but due to new variants in my input things are not working right and throwing errors.

我意识到问题在于它现在正试图将一个时髦的句子分配为哈希键(例如下面的键列表)，并且您可能会不喜欢它.有没有一种方法可以在对它进行哈希处理之前对其进行编码，以防止Perl产生任何干扰?

I realise the problem is that it is now trying to assign a funky sentence as the hash key such as the below list of keys and as you might expect, it's not liking it. Is there a way I can encode this before hashing it to prevent any sort of gag from Perl?

Document: Multiple Attribute Equals (#root3 #form input[type=hidden], #root3 #form input[type=radio])
Document: Attribute selector using UTF8 (#root3 span[lang=中文])
Document: Attribute Ends With (#root3 a[href $= 'org/'])
Document: Attribute Contains (#root3 a[href *= 'google'])
Document: Select options via [selected] (#root3 #select1 option[selected])
Document: Select options via [selected] (#root3 #select2 option[selected])
Document: Select options via [selected] (#root3 #select3 option[selected])
Document: Grouped Form Elements (#root3 input[name='foo[bar]'])
Document: :not() Existing attribute (#root3 #form select:not([multiple]))
Document: :not() Equals attribute (#root3 #form select:not([name=select1]))

推荐答案

允许使用任何字符串.不是字符串的任何内容都将首先被字符串化.

Any string is allowed. Anything that's not a string will be stringified first.
