#include <qhttp.h>
The QHttpHeader class contains header information for HTTP.
network.
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/html
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 value() and setValue(), e.g.
header.setValue( "content-type", "text/html" ); QString contentType = 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.
| QHttpHeader::QHttpHeader | ( | ) |
Constructs an empty HTTP header.
| QHttpHeader::QHttpHeader | ( | const QHttpHeader & | header | ) |
Constructs a copy of header.
| QHttpHeader::QHttpHeader | ( | const QString & | str | ) |
Constructs a HTTP header for 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.
| QHttpHeader::~QHttpHeader | ( | ) | [virtual] |
Destructor.
| QHttpHeader::QHttpHeader | ( | ) |
| QHttpHeader::QHttpHeader | ( | const QHttpHeader & | header | ) |
| QHttpHeader::QHttpHeader | ( | const QString & | str | ) |
| virtual QHttpHeader::~QHttpHeader | ( | ) | [virtual] |
| uint QHttpHeader::contentLength | ( | ) | const |
Returns the value of the special HTTP header field content-length.
| uint QHttpHeader::contentLength | ( | ) | const |
| QString QHttpHeader::contentType | ( | ) | const |
Returns the value of the special HTTP header field content-type.
| QString QHttpHeader::contentType | ( | ) | const |
| bool QHttpHeader::hasContentLength | ( | ) | const |
Returns TRUE if the header has an entry for the special HTTP header field content-length; otherwise returns FALSE.
| bool QHttpHeader::hasContentLength | ( | ) | const |
| bool QHttpHeader::hasContentType | ( | ) | const |
Returns TRUE if the header has an entry for the the special HTTP header field content-type; otherwise returns FALSE.
| bool QHttpHeader::hasContentType | ( | ) | const |
Returns TRUE if the HTTP header has an entry with the given key; otherwise returns FALSE.
| bool QHttpHeader::isValid | ( | ) | const |
| bool QHttpHeader::isValid | ( | void | ) | const |
Returns TRUE if the HTTP header is valid; otherwise returns FALSE.
A QHttpHeader is invalid if it was created by parsing a malformed string.
| QStringList QHttpHeader::keys | ( | ) | const |
| QStringList QHttpHeader::keys | ( | ) | const |
Returns a list of the keys in the HTTP header.
| virtual int QHttpHeader::majorVersion | ( | ) | const [pure virtual] |
Implementado en QHttpResponseHeader, QHttpRequestHeader, QHttpResponseHeader y QHttpRequestHeader.
| int QHttpHeader::majorVersion | ( | ) | const [pure virtual] |
Returns the major protocol-version of the HTTP header.
Implementado en QHttpResponseHeader, QHttpRequestHeader, QHttpResponseHeader y QHttpRequestHeader.
| int QHttpHeader::minorVersion | ( | ) | const [pure virtual] |
Returns the minor protocol-version of the HTTP header.
Implementado en QHttpResponseHeader, QHttpRequestHeader, QHttpResponseHeader y QHttpRequestHeader.
| virtual int QHttpHeader::minorVersion | ( | ) | const [pure virtual] |
Implementado en QHttpResponseHeader, QHttpRequestHeader, QHttpResponseHeader y QHttpRequestHeader.
| QHttpHeader & QHttpHeader::operator= | ( | const QHttpHeader & | h | ) |
Assigns h and returns a reference to this http header.
| QHttpHeader& QHttpHeader::operator= | ( | const QHttpHeader & | h | ) |
Reimplementado en QHttpResponseHeader, QHttpRequestHeader, QHttpResponseHeader y QHttpRequestHeader.
Reimplementado en QHttpResponseHeader, QHttpRequestHeader, QHttpResponseHeader y QHttpRequestHeader.
| void QHttpHeader::removeValue | ( | const QString & | key | ) |
Removes the entry with the key key from the HTTP header.
| void QHttpHeader::removeValue | ( | const QString & | key | ) |
| void QHttpHeader::setContentLength | ( | int | len | ) |
| void QHttpHeader::setContentLength | ( | int | len | ) |
Sets the value of the special HTTP header field content-length to len.
| void QHttpHeader::setContentType | ( | const QString & | type | ) |
Sets the value of the special HTTP header field content-type to type.
| void QHttpHeader::setContentType | ( | const QString & | type | ) |
| void QHttpHeader::setValid | ( | bool | ) | [protected] |
| void QHttpHeader::setValid | ( | bool | v | ) | [protected] |
Sets the value of the entry with the key to value.
If no entry with key exists, a new entry with the given key and value is created. If an entry with the key already exists, its value is discarded and replaced with the given value.
| QString QHttpHeader::toString | ( | ) | const [virtual] |
Returns a string representation of the HTTP header.
The string is suitable for use by the constructor that takes a QString. It consists of lines with the format: key, colon, space, value, "\r\n".
Reimplementado en QHttpResponseHeader, QHttpRequestHeader, QHttpResponseHeader y QHttpRequestHeader.
| virtual QString QHttpHeader::toString | ( | ) | const [virtual] |
Reimplementado en QHttpResponseHeader, QHttpRequestHeader, QHttpResponseHeader y QHttpRequestHeader.
Returns the value for the entry with the given key. If no entry has this key, an empty string is returned.
