Detailed Description

The upload manager allows to upload a file to a server via XEP-0363: HTTP File Upload. This can be used for sending files to other users.

QXmppHttpUploadManager depends on QXmppDiscoveryManager.

Since

QXmpp 1.5

Member Enumeration Documentation

Support

enum class QXmppHttpUploadManager::Support

strong

Server support for the feature.

Enumerator
Unknown	Whether the server supports the feature is not known. That means, there is no corresponding information from the server (yet).
Unsupported	The server does not support the feature.
Supported	The server supports the feature. Since QXmpp 1.13

Member Function Documentation

onRegistered()

void QXmppHttpUploadManager::onRegistered ( QXmppClient * client )

overrideprotectedvirtual

Called after the extension has been added to a QXmppClient.

Parameters

client

Reimplemented from QXmppClientExtension.

onUnregistered()

void QXmppHttpUploadManager::onUnregistered ( QXmppClient * client )

overrideprotectedvirtual

Called after the extension has been removed from a QXmppClient.

Parameters

client

Reimplemented from QXmppClientExtension.

services()

QVector< QXmppHttpUploadService > QXmppHttpUploadManager::services

(

)

const

Returns all discovered HTTP File Upload services.

support()

QXmppHttpUploadManager::Support QXmppHttpUploadManager::support

(

)

const

Returns the server's support for upload services.

uploadFile() [1/2]

std::shared_ptr< QXmppHttpUpload > QXmppHttpUploadManager::uploadFile	(	const QFileInfo &	fileInfo,
		const QString &	filename = {},
		const QString &	uploadServiceJid = {} )

Upload data from a local file.

Parameters

fileInfo	QFileInfo about a local file
filename	filename How the file on the server should be called. This is commonly used as last part of the resulting url.
uploadServiceJid	optionally, the jid from which an upload url can be requested (upload service)

Returns

an object representing the ongoing upload. The object is passed as a shared_ptr, which means it will be stored as long as there is a reference to it. While this avoids errors from accessing it after it was deleted, you should try not store it unneccesarily long to keep the memory usage down. You can for example use std::weak_ptr to not increase the lifetime, for example when capturing in long living lambdas, for example in connects. You should also make sure to use the 4-arg QObject::connect, so the connection and the connected lambda can be deleted after the upload finished.

std::weak_ptr<QXmppHttpUpload> uploadPtr = upload;
connect(upload.get(), &QXmppHttpUpload::progressChanged, this, [uploadPtr]() {
    auto upload = uploadPtr.lock();
    if (upload) {
        qDebug() << upload->progress();
    }
});

uploadFile() [2/2]

std::shared_ptr< QXmppHttpUpload > QXmppHttpUploadManager::uploadFile	(	std::unique_ptr< QIODevice >	data,
		const QString &	filename,
		const QMimeType &	mimeType,
		qint64	fileSize = -1,
		const QString &	uploadServiceJid = {} )

Uploads the data from a QIODevice.

Parameters

data	QIODevice to read the data from. This can for example be a QFile. It can be sequential or non-sequential.
filename	How the file on the server should be called. This is commonly used as last part of the resulting url.
fileSize	The size of the file, in byte. If negative the size from the IO device is used.
mimeType	The mime type of the file
uploadServiceJid	optionally, the jid from which an upload url can be requested (upload service)

Returns

an object representing the ongoing upload. The object is passed as a shared_ptr, which means it will be stored as long as there is a reference to it. While this avoids errors from accessing it after it was deleted, you should try not store it unneccesarily long to keep the memory usage down. You can for example use std::weak_ptr to not increase the lifetime, for example when capturing in long living lambdas, for example in connects. You should also make sure to use the 4-arg QObject::connect, so the connection and the connected lambda can be deleted after the upload finished.

std::weak_ptr<QXmppHttpUpload> uploadPtr = upload;

    auto upload = uploadPtr.lock();
    if (upload) {
        qDebug() << upload->progress();
    }
