使用变量访问golang结构字段

For reference: example here

I am trying to access a struct field using a variable key, to explain in PHP you can do the below.

$arr = ["test" => "foo"];
$key = "test";
$result = $arr[$key];

Or in Javascript you can do the below

const obj = {"test": "foo"}
const key = "test"
const result = obj[key]

Is this possible with go structs? I have searched for this functionality, but the answers always seem to point to the reflect package and running a for loop over the struct fields.

My code (linked above) gets the compile error of invalid operation: p[key] (type Post does not support indexing) which makes sense, but I can't find a way around this.
