DESCRIPTION

36       The QHttpHeader class contains header information for HTTP.
37
38       In most cases you should use the more specialized derivatives of this
39       class, QHttpResponseHeader and QHttpRequestHeader, rather than directly
40       using QHttpHeader.
41
42       QHttpHeader provides the HTTP header fields. A HTTP header field
43       consists of a name followed by a colon, a single space, and the field
44       value. (See RFC 1945.) Field names are case-insensitive. A typical
45       header field looks like this:
46
47           content-type: text/html
48
49       In the API the header field name is called the "key" and the content is
50       called the "value". You can get and set a header field's value by using
51       its key with value() and setValue(), e.g.
52
53           header.setValue( "content-type", "text/html" );
54           QString contentType = header.value( "content-type" );
55
56       Some fields are so common that getters and setters are provided for
57       them as a convenient alternative to using value() and setValue(), e.g.
58       contentLength() and contentType(), setContentLength() and
59       setContentType().
60
61       Each header key has a single value associated with it. If you set the
62       value for a key which already exists the previous value will be
63       discarded.
64
65       See also QHttpRequestHeader, QHttpResponseHeader, and Input/Output and
66       Networking.

MEMBER FUNCTION DOCUMENTATION

QHttpHeader::QHttpHeader ()

70       Constructs an empty HTTP header.
71

QHttpHeader::QHttpHeader ( const QHttpHeader & header )

73       Constructs a copy of header.
74

QHttpHeader::QHttpHeader ( const QString & str )

76       Constructs a HTTP header for str.
77
78       This constructor parses the string str for header fields and adds this
79       information. The str should consist of one or more" \r\n" delimited
80       lines; each of these lines should have the format key, colon, space,
81       value.
82

QHttpHeader::~QHttpHeader () [virtual]

84       Destructor.
85

uint QHttpHeader::contentLength () const

87       Returns the value of the special HTTP header field content-length.
88
89       See also setContentLength() and hasContentLength().
90

QString QHttpHeader::contentType () const

92       Returns the value of the special HTTP header field content-type.
93
94       See also setContentType() and hasContentType().
95

bool QHttpHeader::hasContentLength () const

97       Returns TRUE if the header has an entry for the special HTTP header
98       field content-length; otherwise returns FALSE.
99
100       See also contentLength() and setContentLength().
101

bool QHttpHeader::hasContentType () const

103       Returns TRUE if the header has an entry for the the special HTTP header
104       field content-type; otherwise returns FALSE.
105
106       See also contentType() and setContentType().
107

bool QHttpHeader::hasKey ( const QString & key ) const

109       Returns TRUE if the HTTP header has an entry with the given key;
110       otherwise returns FALSE.
111
112       See also value(), setValue(), and keys().
113

bool QHttpHeader::isValid () const

115       Returns TRUE if the HTTP header is valid; otherwise returns FALSE.
116
117       A QHttpHeader is invalid if it was created by parsing a malformed
118       string.
119

QStringList QHttpHeader::keys () const

121       Returns a list of the keys in the HTTP header.
122
123       See also hasKey().
124

int QHttpHeader::majorVersion () const [pure virtual]

126       Returns the major protocol-version of the HTTP header.
127
128       Reimplemented in QHttpResponseHeader and QHttpRequestHeader.
129

int QHttpHeader::minorVersion () const [pure virtual]

131       Returns the minor protocol-version of the HTTP header.
132
133       Reimplemented in QHttpResponseHeader and QHttpRequestHeader.
134

QHttpHeader & QHttpHeader::operator= ( const QHttpHeader & h )

136       Assigns h and returns a reference to this http header.
137

void QHttpHeader::removeValue ( const QString & key )

139       Removes the entry with the key key from the HTTP header.
140
141       See also value() and setValue().
142

void QHttpHeader::setContentLength ( int len )

144       Sets the value of the special HTTP header field content-length to len.
145
146       See also contentLength() and hasContentLength().
147

void QHttpHeader::setContentType ( const QString & type )

149       Sets the value of the special HTTP header field content-type to type.
150
151       See also contentType() and hasContentType().
152
153       Example: network/archivesearch/archivedialog.ui.h.
154

void QHttpHeader::setValue ( const QString & key, const QString & value )

156       Sets the value of the entry with the key to value.
157
158       If no entry with key exists, a new entry with the given key and value
159       is created. If an entry with the key already exists, its value is
160       discarded and replaced with the given value.
161
162       See also value(), hasKey(), and removeValue().
163
164       Example: network/archivesearch/archivedialog.ui.h.
165

QString QHttpHeader::toString () const [virtual]

167       Returns a string representation of the HTTP header.
168
169       The string is suitable for use by the constructor that takes a QString.
170       It consists of lines with the format: key, colon, space, value, "\r\n".
171

QString QHttpHeader::value ( const QString & key ) const

173       Returns the value for the entry with the given key. If no entry has
174       this key, an empty string is returned.
175
176       See also setValue(), removeValue(), hasKey(), and keys().
