Unmarshal JSON with unknown field name
<p>I have a JSON object, something like this:</p>

<pre><code>{
    "randomstring": {
        "everything": "here",
        "is": "known"
    }
}
</code></pre>

<p>Basically everything inside the <code>randomstring</code> object is known, I can model that, but the <em>randomstring</em> itself is random. I know what it's going to be, but it's different every time. Basically all the data I need is in the <em>randomstring</em> object. How could I parse this kind of JSON to get the data?</p>
