Have you tried: <a href="http://flori.github.com/json/" rel="nofollow noreferrer">http://flori.github.com/json/</a>?

Failing that, you could just parse it out? If it's only arrays you're interested in, something to split the above out will be quite simple.

blocks|key|742761|text|下面的代码片段怎么样？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|742762|require+'json'
value+=+'{"val":"test","val1":"test1","val2":"test2"}'
puts+JSON.parse(value)+#+=>+{"val"=>"test","val1"=>"test1","val2"=>"test2"}|code-block|syntax|javascript|742763|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

What about the following snippet?

<pre><code>require 'json'
value = '{"val":"test","val1":"test1","val2":"test2"}'
puts JSON.parse(value) # =&gt; {"val"=&gt;"test","val1"=&gt;"test1","val2"=&gt;"test2"}
</code></pre>

blocks|key|742795|text|假设您有一个JSON散列，要自动将其转换为类似WarHog版本的内容，请将您的JSON散列内容包装在%25q{hsh}标记中。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|742796|这似乎会自动添加所有必要的转义文本，就像WarHog的答案一样。|742797|entityMap^0|1E|7|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

Assuming you have a JSON hash hanging around somewhere, to automatically convert it into something like WarHog's version, wrap your JSON hash contents in <code>%q{hsh}</code> tags. 

This seems to automatically add all the necessary escaped text like in WarHog's answer.

blocks|key|742834|text|您还可以使用Rails的with_indifferent_access方法，这样就可以使用符号或字符串访问正文。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|742835|value+=+'{"val":"test","val1":"test1","val2":"test2"}'
json+=+JSON.parse(value).with_indifferent_access|code-block|syntax|javascript|742836|然后|742837|json[:val]+#=>+"test"

You could also use Rails' <a href="https://api.rubyonrails.org/classes/ActiveSupport/HashWithIndifferentAccess.html#method-i-with_indifferent_access" rel="noreferrer"><code>with_indifferent_access</code></a> method so you could access the body with either symbols or strings.

<pre><code>value = '{"val":"test","val1":"test1","val2":"test2"}'
json = JSON.parse(value).with_indifferent_access
</code></pre>

then 

<pre><code>json[:val] #=&gt; "test"

json["val"] #=&gt; "test"
</code></pre>

blocks|key|742857|text|您可以使用nice_hash+gem：https://github.com/MarioRuiz/nice_hash|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|742858|require+'nice_hash'

You can use the nice_hash gem: <a href="https://github.com/MarioRuiz/nice_hash" rel="nofollow noreferrer">https://github.com/MarioRuiz/nice_hash</a>

<pre><code>require 'nice_hash'
my_string = '{"val":"test","val1":"test1","val2":"test2"}'

# on my_hash will have the json as a hash, even when nested with arrays
my_hash = my_string.json

# you can filter and get what you want even when nested with arrays
vals = my_string.json(:val1, :val2)

# even you can access the keys like this:
puts my_hash._val1
puts my_hash.val1
puts my_hash[:val1]
</code></pre>

I have a JSON object holding the following value:

<pre><code>@value = {"val":"test","val1":"test1","val2":"test2"}
</code></pre>

I want to loop through it in Ruby to get the key/value pairs. When I use <code>@each</code>, it doesn't iterate through the object because it is not in the Ruby hash form:

<pre><code>@value = {"val"=&gt;"test","val1"=&gt;"test1","val2"=&gt;"test2"}
</code></pre>

How can I convert the above JSON object to a Ruby hash?

我有一个包含以下值的JSON对象：@value = {"val":"test","val1":"test1","val2":"test2"}我想在Ruby中遍历它以获得键/值对。当我使用@each时，它不会遍历对象，因为它不是Ruby散列形式的：@value = {"val"=>"test","val1"=>"test...
