        <h3>Description</h3>
        <p><span>This function returns a bidirectional</span> <span>view of key/value pairs over the query.</span>
<span>The returned view references the same</span>
<span>underlying character buffer; ownership</span>
<span>is not transferred.</span>
<span>Any percent-escapes in strings returned</span>
<span>when iterating the view are decoded first.</span>
<span>The container is modifiable; changes</span>
<span>to the container are reflected in the</span>
<span>underlying URL.</span></p>

<h3>Example</h3>
<code>
encoding_opts opt;
opt.space_as_plus = true;
params_ref pv = url( "/sql?id=42&name=jane+doe&page+size=20" ).params(opt);
</code>
<h3>Complexity</h3>
<p><span>Constant.</span></p>

<h3>Exception Safety</h3>
<p><span>Throws nothing.</span></p>

<h3>BNF</h3>
<code>
query           = *( pchar / "/" / "?" )

query-param     = key [ "=" value ]
query-params    = [ query-param ] *( "&" query-param )
</code>
