Detailed Description

Uses XEP-0191: Blocking Command to manage blocked accounts and services.

Use Cases

• listing blocked devices, accounts and servers
• blocking and unblocking JIDs
• getting notified when a new JID has been blocked or unblocked

Listing blocked devices

You can receive a list of blocked JIDs by using fetchBlocklist().

manager->fetchBlocklist().then(this, [](auto result) {
    if (auto *blocklist = std::get_if<QXmppBlocklist>(&result)) {
        qDebug() << "Blocked JIDs:" << blocklist->entries();
    } else if (auto *err = std::get_if<QXmppError>(&result)) {
        qDebug() << "Error fetching blocklist:" << err->description;
    }
});

The server will send updates to us for the rest of the stream. You can listen to the updates by connecting to blocked() and unblocked().

Note

The manager caches the blocklist, so after the first time the task will finish instantly.

Blocking and Unblocking

You can use block() and unblock() for this purpose.

manager->block("baduser@spam.im").then(this, [](auto result) {
    if (std::holds_alternative<QXmpp::Success>(result)) {
        qDebug() << "Blocked baduser@spam.im!";
    } else if (auto *err = std::get_if<QXmppError>(&result)) {
        qDebug() << "Error:" << err->description;
    }
});

unblock() works likewise.

Note

This will also trigger blocked() or unblocked() if you are subscribed to the blocklist.

Blocklist Subscription

You will automatically receive blocklist updates after you requested the blocklist. You can connect to the blocked() and unblocked() signals.

Format

It is important to notice that the blocked JIDs are not limited to accounts, allowed are the following formats:

• user@domain/resource
• user@domain
• domain/resource
• domain

It is not possible to block a domain without blocking a specific account though (or another combination).

Setup

The blocking manager is not enabled by default and needs to be registered with your QXmppClient.

auto *blockingManager = client->addNewExtension<QXmppBlockingManager>();

Member Function Documentation

block() [1/2]

QXmppBlockingManager::block ( QString  jid )

inline

Blocks a JID.

See also

unblock()

block() [2/2]

QXmppTask< QXmppBlockingManager::Result > QXmppBlockingManager::block

(

QVector< QString >

jids

)

Blocks a list of JIDs.

See also

unblock()

blocked()

QXmppBlockingManager::blocked

(

const QVector< QString > &

jids

)

Emitted when a blocklist update with new blocked JIDs has been received.

This is also emitted when you call block().

fetchBlocklist()

QXmppTask< QXmppBlockingManager::BlocklistResult > QXmppBlockingManager::fetchBlocklist

(

)

Fetches the list of blocked JIDs and subscribes to blocklist updates.

The manager will cache the blocklist and keep track of updates for the rest of the session. Later calls of this function will report the cached result immediately. Even calling this function multiple times before the first request has finished, will not trigger more than one IQ request being sent.

isSubscribed()

bool QXmppBlockingManager::isSubscribed

(

)

const

Returns whether the blocking manager currently receives updates of the blocklist.

The subscription is enabled automatically after fetching the blocklist using fetchBlocklist().

subscribedChanged()

QXmppBlockingManager::subscribedChanged

(

)

Called whenever the state of the subscription to blocklist updates has changed.

unblock() [1/2]

QXmppBlockingManager::unblock ( QString  jid )

inline

Unblocks a JID.

See also

block()

unblock() [2/2]

QXmppTask< QXmppBlockingManager::Result > QXmppBlockingManager::unblock

(

QVector< QString >

jids

)

Unblocks a list of JIDs.

See also

block()

unblocked()

QXmppBlockingManager::unblocked

(

const QVector< QString > &

jids

)

Emitted when a blocklist update with new unblocked JIDs has been received.

This is also emitted when you call unblock().
