如何在Ruby中使用单引号(')解析JSON字符串? [英] How to parse JSON strings with single quotes (') in Ruby?

问题描述

我正在尝试像这样解析JSON字符串:

I am trying to parse a JSON String like this:

JSON.parse("{'foo' : 42 }")

但是，这会产生一个JSON :: ParseError:

However, this yields a JSON::ParseError:

JSON::ParserError: 757: unexpected token at '{'foo' : 42 }'
    from /Users/nils/.rvm/rubies/ruby-2.1.2/lib/ruby/2.1.0/json/common.rb:155:in `parse'
    from /Users/nils/.rvm/rubies/ruby-2.1.2/lib/ruby/2.1.0/json/common.rb:155:in `parse'
    from (irb):2
    from /Users/nils/.rvm/rubies/ruby-2.1.2/bin/irb:11:in `<main>'

我认为它期望'字符是"字符.由于我有多个GB的此类文件，因此我想使解析器与此一起工作.由于某些值可能还包含'个字符，因此我不能简单地对它们进行搜索和替换，因为这可能会破坏原始内容.

I think it expects the ' character to be a " character. Since I have multiple gigabytes of such files I would like to make the parser work with this. Since some of the values may also include ' characters I can't simply run search and replace over them because that may destroy the original content.

关于如何使JSON解析器解析的任何建议吗?

Any suggestions on how to make the JSON parser parse this?

推荐答案

JSON.parse("{'foo' : 42 }")

这不是JSON字符串.

That's not a JSON string.

但是，这会产生一个JSON::ParseError:

这是正确的，因为字符串不是JSON.

Which is correct, since the string is not JSON.

您无法使用JSON解析器对此进行解析，因为它不是JSON.

You cannot parse this with a JSON parser because it's not JSON.

您需要弄清楚它是什么语言，然后使用该语言的解析器.

You need to figure out what language it is, and then use a parser for that language.

您发布的代码段看起来像 YAML ，但当然这可能是偶然的.

The snippet you posted looks like YAML, but of course that could just be accidental.

require 'yaml'

YAML.load("{'foo' : 42 }")
# => { "foo" => 42 }

但是请注意，尝试从一个简短的示例中猜测语言很容易出错.您应该与该序列化的产生者商议，并询问他们是哪种语言.

But note that trying to guess the language from one single, short example is highly error-prone. You should confer with the producer of that serialization and ask them what language it is.
