<h2 id="extractor-behaviour"><a href="#extractor-behaviour">Extractor Behaviour</a></h2>
|
||
<p>What happens if you try to extract an <code>Identity</code> out of a request that does not have a valid
|
||
identity attached? The API will return a <code>401 UNAUTHORIZED</code> to the caller.</p>
|
||
<p>If you want to customise this behaviour, consider extracting <code>Option<Identity></code> or
|
||
<code>Result<Identity, actix_web::Error></code> instead of a bare <code>Identity</code>: you will then be fully in
|
||
control of the error path.</p>
