    the optional parameters

Options Hash (opts):

  • :headers (Hash<String, String>) —

    HTTP headers to pass to the target page. Can be specified either via a nested query parameter (…&amp;headers&#x3D;value1&amp;headers&#x3D;&#x3D;value2) or as a JSON encoded object (…&amp;headers&#x3D;&quot;value1&quot;, &quot;Another&quot;: &quot;value2&quot;).
