https://www.exceptionalcreatures.com/bestiary/Net/OpenTimeout

是因为时间超时了，时间是可以自己设置的：

<span class="c1"># net_timeout_1.rb</span>
<span class="nb">require</span> <span class="s1">&#39;net/http&#39;</span>
<span class="c1"># create a new http connection object, the connection isn&#39;t made yet</span>
<span class="n">c</span> <span class="o">=</span> <span class="no">Net</span><span class="o">::</span><span class="no">HTTP</span><span class="p">.</span><span class="nf">new</span><span class="p">(</span><span class="s2">&quot;www.example.com&quot;</span><span class="p">)</span>
<span class="c1"># set the open timeout to 1ms</span>
<span class="c1"># i.e. if we can&#39;t open a connection within 1ms this will cause a</span>
<span class="c1"># Net::OpenTimeout error when the request is made</span>
<span class="n">c</span><span class="p">.</span><span class="nf">open_timeout</span> <span class="o">=</span> <span class="mf">0.001</span>
<span class="c1"># make a get request after opening a connection</span>
<span class="n">response</span> <span class="o">=</span> <span class="n">c</span><span class="p">.</span><span class="nf">request_get</span><span class="p">(</span><span class="s2">&quot;/index.html&quot;</span><span class="p">)</span>
<span class="c1"># print the response status code</span>
<span class="nb">puts</span> <span class="s2">&quot;RESPONSE STATUS CODE: </span><span class="si">#{</span><span class="n">response</span><span class="p">.</span><span class="nf">code</span><span class="si">}</span><span class="s2">&quot;</span>

运行：


<span class="nv">$ </span>ruby net_timeout_1.rb
<span class="c"># =&gt; ../net/http.rb:904:in `initialize&#39;: execution expired (Net::OpenTimeout)</span>
