public abstract class QHttpHeader
The QHttpHeader
class contains header information for HTTP. In most cases you should use the more specialized derivatives of this class, QHttpResponseHeader
and QHttpRequestHeader
, rather than directly using QHttpHeader
.
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:
content-type: text/htmlIn 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
value()
and setValue()
, e.g. header.setValue("content-type", "text/html"); StringscontentType = header.value("content-type");Some fields are so common that getters and setters are provided for them as a convenient alternative to using
value()
and setValue()
, e.g. contentLength()
and contentType()
, setContentLength()
and setContentType()
. Each header key has a single value associated with it. If you set the value for a key which already exists the previous value will be discarded.

public QHttpHeader()
public QHttpHeader(QHttpHeader header)
public QHttpHeader(java.lang.String str)
This constructor parses the string str for header fields and adds this information. The str should consist of one or more "\r\n" delimited lines; each of these lines should have the format key, colon, space, value.
