<p>If you are already using the <a href="https://requests.readthedocs.io/en/master/">requests</a>
|
|
library, it is convenient to also use it here:</p>
|
|
<div class="python highlight"><pre><span></span><code><span class="kn">import</span> <span class="nn">requests</span>
|
|
|
|
<span class="k">try</span><span class="p">:</span>

|
<span class="n">requests</span><span class="o">.</span><span class="n">get</span><span class="p">(</span><span class="s2">"PING_URL"</span><span class="p">,</span> <span class="n">timeout</span><span class="o">=</span><span class="mi">10</span><span class="p">)</span>
|

<span class="k">except</span> <span class="n">requests</span><span class="o">.</span><span class="n">RequestException</span> <span class="k">as</span> <span class="n">e</span><span class="p">:</span>

<span class="c1"># Log ping failure here...</span>
|

<span class="nb">print</span><span class="p">(</span><span class="s2">"Ping failed: </span><span class="si">%s</span><span class="s2">"</span> <span class="o">%</span> <span class="n">e</span><span class="p">)</span>

<p>Otherwise, you can use the <a href="https://docs.python.org/3/library/urllib.request.html">urllib.request</a>
|
|
module from Python 3 standard library:</p>
|
|
<div class="python highlight"><pre><span></span><code><span class="kn">import</span> <span class="nn">socket</span>
|
|
<span class="kn">import</span> <span class="nn">urllib.request</span>

<p>You can include additional diagnostic information in the in the request body (for POST requests):</p>
|
|
<div class="python highlight"><pre><span></span><code><span class="c1"># Passing diagnostic information in the POST body:</span>
