Channels

Search open channels by name, URL, or custom type

You can search for specific open channels by adding keywords to an SBDOpenChannelListQuery instance. There are two types of keywords: a Name and a URL. The code sample below shows the query instance which returns a list of open channels that partially match the specified Name keyword in the names of the channels.

SBDOpenChannelListQuery* query = SBDOpenChannel::CreateOpenChannelListQuery();

query->SetChannelNameFilter(L"Sendbird");
query->LoadNextPage([](vector<SBDOpenChannel*> openChannels, SBDError* error) {
    if (error != nullptr) {
        // Handle error.
        return;
    }

    // Through the openChannels parameter of the handler callback function, 
    // which the Sendbird server has passed a result list to,
    // a list of open channels that have 'Sendbird' in their names is returned.
});

The following shows the query instance which returns a list of open channels that partially match the specified URL keyword in the URLs of the channels.

SBDOpenChannelListQuery* query = SBDOpenChannel::CreateOpenChannelListQuery();

query->SetChannelUrlFilter(L"seminar");
query->LoadNextPage([](vector<SBDOpenChannel*> openChannels, SBDError* error) {
    if (error != nullptr) {
        // Handle error.
        return;
    }

    // Through the openChannels parameter of the handler callback function, 
    // which the Sendbird server has passed a result list to,
    // a list of open channels that have 'seminar' in their URLs is returned.
});

Using the SetCustomTypeFilter() like the following, you can also search for open channels with a specific custom type.

SBDOpenChannelListQuery* query = SBDOpenChannel::CreateOpenChannelListQuery();

query->SetCustomTypeFilter(L"movie");
query->LoadNextPage([](vector<SBDOpenChannel*> openChannels, SBDError* error) {
    if (error != nullptr) {
        // Handle error.
        return;
    }

    // Through the openChannels parameter of the handler callback function,
    // which the Sendbird server has passed a result list to,
    // a list of open channels with a 'movie' custom type is returned.
});
