name="details"></a> <!-- $$$QHttpHeader-description --> <div class="descr"> <h2>Detailed Description</h2> <p>The QHttpHeader class contains header information for HTTP.</p> <p>In most cases you should use the more specialized derivatives of this class, <a href="qhttpresponseheader.html">QHttpResponseHeader</a> and <a href="qhttprequestheader.html">QHttpRequestHeader</a>, rather than directly using QHttpHeader.</p> <p>QHttpHeader provides the HTTP header fields. A HTTP header field consists of a name followed by a colon, a single space, and the field value. (See RFC 1945.) Field names are case-insensitive. A typical header field looks like this:</p> <pre class="cpp"> content<span class="operator">-</span>type: text<span class="operator">/</span>html</pre> <p>In the API the header field name is called the "key" and the content is called the "value". You can get and set a header field's value by using its key with <a href="qhttpheader.html#value">value</a>() and <a href="qhttpheader.html#setValue">setValue</a>(), e.g.</p> <pre class="cpp"> header<span class="operator">.</span><a href="qhttpheader.html#setValue">setValue</a>(<span class="string">"content-type"</span><span class="operator">,</span> <span class="string">"text/html"</span>); <span class="type"><a href="qstring.html">QString</a></span> contentType <span class="operator">=</span> header<span class="operator">.</span><a href="qhttpheader.html#value">value</a>(<span class="string">"content-type"</span>);</pre> <p>Some fields are so common that getters and setters are provided for them as a convenient alternative to using <a href="qhttpheader.html#value">value</a>() and <a href="qhttpheader.html#setValue">setValue</a>(), e.g. <a href="qhttpheader.html#contentLength">contentLength</a>() and <a href="qhttpheader.html#contentType">contentType</a>(), <a href="qhttpheader.html#setContentLength">setContentLength</a>() and <a href="qhttpheader.html#setContentType">setContentType</a>().</p> <p>Each header key has a <i>single</i> value associated with it. If you set the value for a key which already exists the previous value will be discarded.</p> </div> <p><b>See also </b><a href="qhttprequestheader.html">QHttpRequestHeader</a> and <a href="qhttpresponseheader.html">QHttpResponseHeader</a>.</p> <!-- @@@QHttpHeader --> <div class="func"> <h2>Member Function Documentation</h2> <!-- $$$QHttpHeader[overload1]$$$QHttpHeader --> <h3 class="fn"><a name="QHttpHeader"></a>QHttpHeader::<span class="name">QHttpHeader</span> ()</h3> <p>Constructs an empty HTTP header.</p> <!-- @@@QHttpHeader --> <!-- $$$QHttpHeader$$$QHttpHeaderconstQHttpHeader& --> <h3 class="fn"><a name="QHttpHeader-2"></a>QHttpHeader::<span class="name">QHttpHeader</span> ( const <span class="type">QHttpHeader</span> & <i>header</i> )</h3> <p>Constructs a copy of <i>header</i>.</p> <!-- @@@QHttpHeader --> <!-- $$$QHttpHeader$$$QHttpHeaderconstQString& --> <h3 class="fn"><a name="QHttpHeader-3"></a>QHttpHeader::<span class="name">QHttpHeader</span> ( const <span class="type"><a href="qstring.html">QString</a></span> & <i>str</i> )</h3> <p>Constructs a HTTP header for <i>str</i>.</p> <p>This constructor parses the string <i>str</i> for header fields and adds this information.
