How to exponential back off with network requests

<p>Hello everyone.</p> <p>I&#39;ve been writing some code that makes quick and dirty http requests and I realised my code is brittle because it will error if any request fails even once.</p> <p>What are some simple &#39;ways&#39; I can use exponential back off when making http requests? Can I do it with the standard lib (in an opaque manner)? Do I need a thin library? How have you done it in practice? </p> <p>Cheers!</p> <hr/>**评论：**<br/><br/>wilywes: <pre><p>My favourite library for this is <a href="https://github.com/sethgrid/pester" rel="nofollow">Pester </a>. There&#39;s a few others and it&#39;s simple enough that you could use the stdlib (pester has no dependencies). </p></pre>bmurphy1976: <pre><p>I wrote this a couple years back and we use it in some of our software. It doesn&#39;t support jitter or alternative backoff algorithms like the the library <a href="/u/wilywes" rel="nofollow">/u/wilywes</a> posted, but it&#39;s a bit more generic and useful in other situations:</p> <p><a href="https://github.com/mediafly/retry" rel="nofollow">https://github.com/mediafly/retry</a></p> <p>Could probably use some polish but it gets the job done. </p></pre>
