Have a look at the one from mochiweb: <a href="https://github.com/mochi/mochiweb/blob/master/src/mochijson.erl" rel="nofollow noreferrer">mochijson.erl</a>

<pre><code>1&gt; mochijson:decode("{\"Name\":\"Tom\",\"Age\":10}").

blocks|key|1095330|text|我最喜欢的是mochijson2。API很简单，对我来说已经足够快了(老实说，我实际上从来没有费心对它进行基准测试--我主要是对小数据包进行编码和解码)，并且我已经在一个稳定的“生产服务器”中使用它一年左右了。记住也要安装mochinum，mochijson2使用它来编码大数字，如果你错过了它，而你试图编码一个大数字，它会抛出一个异常。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1095331|另请参阅：mochijson2+examples+(stackoverflow)|offset|length|1095332|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/1000046/mochijson2-examples^0|0|5|Z|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

My favourite is mochijson2. The API is straightforward, it's fast enough for me (I never actually bothered to benchmark it though, to be honest--I'm mostly en- and de-coding small packets), and I've been using it in a stable "production server" for a year now or so. Just remember to install mochinum as well, mochijson2 uses it to encode large numbers, if you miss it, and you'll try to encode a large number, it will throw an exception.

blocks|key|1095359|text|我更喜欢Jiffy。它与二进制一起工作，并且速度非常快。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1095360|1>+jiffy:decode(<<"{\"Name\":\"Tom\",\"Age\":10}">>).
{[{<<"Name">>,<<"Tom">>},{<<"Age">>,10}]}|code-block|syntax|javascript|1095361|也可以进行编码：|1095362|2>+jiffy:encode({[{<<"Name">>,<<"Tom">>},{<<"Age">>,10}]}).

I prefer <a href="https://github.com/davisp/jiffy">Jiffy</a>. It works with binary and is realy fast.

<pre><code>1&gt; jiffy:decode(&lt;&lt;"{\"Name\":\"Tom\",\"Age\":10}"&gt;&gt;).
{[{&lt;&lt;"Name"&gt;&gt;,&lt;&lt;"Tom"&gt;&gt;},{&lt;&lt;"Age"&gt;&gt;,10}]}
</code></pre>

Can encode as well:

<pre><code>2&gt; jiffy:encode({[{&lt;&lt;"Name"&gt;&gt;,&lt;&lt;"Tom"&gt;&gt;},{&lt;&lt;"Age"&gt;&gt;,10}]}).
&lt;&lt;"{\"Name\":\"Tom\",\"Age\":10}"&gt;&gt;
</code></pre>

blocks|key|1310556|text|也可以查看jsx。“一个erlang应用程序，用于消费、生产和操作json。灵感来自Yajl。”我自己还没有试过，但它看起来很有前途。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1310557|顺便说一句，我是通过Klarna的json模式验证器Jesse找到这个库的。|1310558|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/talentdeficit/jsx|1|https://klarna.com/sv|2|https://github.com/klarna/jesse^0|5|3|0|0|A|6|1|Q|5|2|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]]|C|$]]|$1|D|3|E|5|6|7|V|8|@]|9|@$A|W|B|X|1|Y]|$A|Z|B|10|1|11]]|C|$]]|$1|F|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]|P|$5|I|J|K|C|$L|Q]]]]

Also check out <a href="https://github.com/talentdeficit/jsx">jsx</a>. "An erlang application for consuming, producing and manipulating json. Inspired by Yajl." I haven't tried it myself yet, but it looks promising.

As a side note; I found this library through <a href="https://github.com/klarna/jesse">Jesse</a>, a json schema validator by <a href="https://klarna.com/sv">Klarna</a>.

I wanted to use YAML but there is not a single mature YAML library for Erlang. I know there are a few JSON libraries, but was wondering which is the most mature?

What is the most mature JSON library for Erlang?

服务器

Erlang

JSON

我想使用YAML，但是还没有一个成熟的用于Erlang的YAML库。我知道有一些JSON库，但我想知道哪一个是最成熟的？
