Member Function Documentation

QHttpPart::QHttpPart()

Constructs an empty QHttpPart object.

QHttpPart::QHttpPart(const QHttpPart &other)

Creates a copy of other.

[noexcept] QHttpPart::~QHttpPart()

Destroys this QHttpPart.

void QHttpPart::setBody(const QByteArray &body)

Sets the body of this MIME part to body. The body set with this method will be used unless the device is set via setBodyDevice(). For a large amount of data (e.g. an image), use setBodyDevice(), which will not copy the data internally.

See also setBodyDevice().

void QHttpPart::setBodyDevice(QIODevice *device)

Sets the device to read the content from to device. For large amounts of data this method should be preferred over setBody(), because the content is not copied when using this method, but read directly from the device. device must be open and readable. QHttpPart does not take ownership of device, i.e. the device must be closed and destroyed if necessary. if device is sequential (e.g. sockets, but not files), QNetworkAccessManager::post() should be called after device has emitted finished(). For unsetting the device and using data set via setBody(), use "setBodyDevice(0)".

See also setBody() and QNetworkAccessManager::post().

void QHttpPart::setHeader(QNetworkRequest::KnownHeaders header, const QVariant &value)

Sets the value of the known header header to be value, overriding any previously set headers.

See also QNetworkRequest::KnownHeaders, setRawHeader(), and QNetworkRequest::setHeader().

void QHttpPart::setRawHeader(const QByteArray &headerName, const QByteArray &headerValue)

Sets the header headerName to be of value headerValue. If headerName corresponds to a known header (see QNetworkRequest::KnownHeaders), the raw format will be parsed and the corresponding "cooked" header will be set as well.

See also QNetworkRequest::KnownHeaders, setHeader(), and QNetworkRequest::setRawHeader().

[noexcept] void QHttpPart::swap(QHttpPart &other)

Swaps this HTTP part with other. This operation is very fast and never fails.

bool QHttpPart::operator!=(const QHttpPart &other) const

Returns true if this object is not the same as other.

See also operator==().

QHttpPart &QHttpPart::operator=(const QHttpPart &other)

Creates a copy of other.

bool QHttpPart::operator==(const QHttpPart &other) const

Returns true if this object is the same as other (i.e., if they have the same headers and body).

See also operator!=().
