Detailed Description

The QXmppUploadRequestManager implements the core of XEP-0369: HTTP File Upload.

It handles the discovery of QXmppUploadServices and can send upload requests and outputs the upload slots. It doesn't do the actual upload via. HTTP.

To make use of this manager, you need to instantiate it and load it into the QXmppClient instance as follows:

auto *manager = new QXmppUploadRequestManager;

client->addExtension(manager);

QXmppClientExtension::client

QXmppClient * client()

Definition QXmppClientExtension.cpp:78

QXmppClient::addExtension

bool addExtension(QXmppClientExtension *extension)

Definition QXmppClient.cpp:263

QXmppUploadRequestManager

The QXmppUploadRequestManager implements the core of XEP-0369: HTTP File Upload.

Definition QXmppUploadRequestManager.h:85

Apart from that, you also need to discover HTTP File Upload service(s) by requesting the Service Discovery info for each Service Discovery item of the server. The QXmppUploadManager will then automatically recognize upload services and add them to the list of discovered services uploadServices().

Keep in mind that theoretically any XMPP entity could promote to be an upload service and so is recognized by this manager. A potential attacker could exploit this vulnerability, so the client could be uploading files to the attacker (e.g. a normal user JID) instead of the own server.

As soon as at least one upload service has been discovered, you can start to request upload slots by using requestUploadSlot(). Alternatively you can provide the JID of the upload service which should be used for uploading.

Since: QXmpp 1.1

Member Typedef Documentation

◆ SlotResult

QXmppUploadRequestManager::SlotResult

Contains the requested upload slot from the service or a QXmppStanza::Error in case the request failed.

Since: QXmpp 1.5

Member Function Documentation

◆ handleStanza()

bool QXmppUploadRequestManager::handleStanza ( const QDomElement & stanza )

overridevirtual

You need to implement this method to process incoming XMPP stanzas.

You should return true if the stanza was handled and no further processing should occur, or false to let other extensions process the stanza.

End-to-end encrypted stanzas are not passed to this overload, for that purpose use the new overload instead.

Deprecated:: This is deprecated since QXmpp 1.5. Please use QXmppClientExtension::handleStanza(const QDomElement &stanza, const std::optional<QXmppE2eeMetadata> &e2eeMetadata). Currently both methods are called by the client, so only implement one!

Reimplemented from QXmppClientExtension.

◆ requestFailed

void QXmppUploadRequestManager::requestFailed ( const QXmppHttpUploadRequestIq & request )

signal

Emitted when the slot request failed.

Parameters

request The sent IQ with an QXmppStanza::Error from the server.

◆ requestSlot() [1/3]

auto QXmppUploadRequestManager::requestSlot	(	const QFileInfo &	file,
		const QString &	customFileName,
		const QString &	uploadService = `{}`
	)

Requests an upload slot from the server.

Parameters

file	The info of the file to be uploaded.
customFileName	This name is used instead of the file's actual name for requesting the upload slot.
uploadService	The HTTP File Upload service that is used to request the upload slot. If this is empty, the first discovered one is used.

Warning: THIS API IS NOT FINALIZED YET!

Since: QXmpp 1.5

◆ requestSlot() [2/3]

auto QXmppUploadRequestManager::requestSlot	(	const QFileInfo &	file,
		const QString &	uploadService = `{}`
	)

Requests an upload slot from the server.

Parameters

file	The info of the file to be uploaded.
uploadService	The HTTP File Upload service that is used to request the upload slot. If this is empty, the first discovered one is used.

Warning: THIS API IS NOT FINALIZED YET!

Since: QXmpp 1.5

◆ requestSlot() [3/3]

auto QXmppUploadRequestManager::requestSlot	(	const QString &	fileName,
		qint64	fileSize,
		const QMimeType &	mimeType,
		const QString &	uploadService = `{}`
	)

Requests an upload slot from the server.

Parameters

fileName	The name of the file to be uploaded. This may be used by the server to generate the URL.
fileSize	The size of the file to be uploaded. The server may reject too large files.
mimeType	The content-type of the file. This can be used by the server to set the HTTP MIME-type of the URL.
uploadService	The HTTP File Upload service that is used to request the upload slot. If this is empty, the first discovered one is used.

Warning: THIS API IS NOT FINALIZED YET!

Since: QXmpp 1.5

◆ requestUploadSlot() [1/3]

QString QXmppUploadRequestManager::requestUploadSlot	(	const QFileInfo &	file,
		const QString &	customFileName,
		const QString &	uploadService = `QString()`
	)

Requests an upload slot from the server.

Parameters

file	The info of the file to be uploaded.
customFileName	This name is used instead of the file's actual name for requesting the upload slot.
uploadService	The HTTP File Upload service that is used to request the upload slot. If this is empty, the first discovered one is used.

Returns: The id of the sent IQ. If sendPacket() isn't successful or no upload service has been discovered yet, an empty string will be returned.

◆ requestUploadSlot() [2/3]

QString QXmppUploadRequestManager::requestUploadSlot	(	const QFileInfo &	file,
		const QString &	uploadService = `QString()`
	)

Requests an upload slot from the server.

Parameters

file	The info of the file to be uploaded.
uploadService	The HTTP File Upload service that is used to request the upload slot. If this is empty, the first discovered one is used.

Returns: The id of the sent IQ. If sendPacket() isn't successful or no upload service has been discovered yet, an empty string will be returned.

◆ requestUploadSlot() [3/3]

QString QXmppUploadRequestManager::requestUploadSlot	(	const QString &	fileName,
		qint64	fileSize,
		const QMimeType &	mimeType,
		const QString &	uploadService = `QString()`
	)

Requests an upload slot from the server.

Parameters

fileName	The name of the file to be uploaded. This may be used by the server to generate the URL.
fileSize	The size of the file to be uploaded. The server may reject too large files.
mimeType	The content-type of the file. This can be used by the server to set the HTTP MIME-type of the URL.
uploadService	The HTTP File Upload service that is used to request the upload slot. If this is empty, the first discovered one is used.

Returns: The id of the sent IQ. If sendPacket() isn't successful or no upload service has been discovered yet, an empty string will be returned.

◆ setClient()

void QXmppUploadRequestManager::setClient ( QXmppClient * client )

overrideprotectedvirtual

Sets the client which loaded this extension.

Parameters

client
