QHttpServerConfiguration Class

Member Function Documentation

QHttpServerConfiguration::QHttpServerConfiguration()

Default constructs a QHttpServerConfiguration object.

Such a configuration has the following values:

• Rate limit is disabled

QHttpServerConfiguration::QHttpServerConfiguration(const QHttpServerConfiguration &other)

Copy-constructs this QHttpServerConfiguration.

[noexcept] QHttpServerConfiguration::QHttpServerConfiguration(QHttpServerConfiguration &&other)

Move-constructs this QHttpServerConfiguration from other

[noexcept] QHttpServerConfiguration::~QHttpServerConfiguration()

Destructor.

[since 6.10] QSpan<const std::pair<QHostAddress, int>> QHttpServerConfiguration::blacklist() const

Returns the blacklist of subnets that are denied access by QHttpServer.

This function was introduced in Qt 6.10.

See also setBlacklist().

[since 6.10] std::chrono::seconds QHttpServerConfiguration::keepAliveTimeout() const

Returns the keep-alive timeout used by QHttpServer.

This function was introduced in Qt 6.10.

See also setKeepAliveTimeout().

quint32 QHttpServerConfiguration::rateLimitPerSecond() const

Returns maximum number of incoming requests per second per IP accepted by the server.

See also setRateLimitPerSecond().

[since 6.10] void QHttpServerConfiguration::setBlacklist(QSpan<const std::pair<QHostAddress, int>> subnetList)

Sets subnetList as the blacklist of subnets.

IP addresses in this list will be denied access by QHttpServer. The blacklist is active only when the whitelist is empty.

This function was introduced in Qt 6.10.

See also blacklist(), setWhitelist(), and QHostAddress::parseSubnet().

[since 6.10] void QHttpServerConfiguration::setKeepAliveTimeout(std::chrono::seconds timeout)

Sets timeout as keep-alive timeout for QHttpServer.

The keep-alive timeout determines how long an idle connection is kept open before being closed. By default, the timeout is set to 15 seconds.

This function was introduced in Qt 6.10.

See also keepAliveTimeout().

void QHttpServerConfiguration::setRateLimitPerSecond(quint32 maxRequests)

Sets maxRequests as the maximum number of incoming requests per second per IP that will be accepted by QHttpServer. If the limit is exceeded, QHttpServer will respond with QHttpServerResponder::StatusCode::TooManyRequests.

See also rateLimitPerSecond() and QHttpServerResponder::StatusCode.

[since 6.10] void QHttpServerConfiguration::setWhitelist(QSpan<const std::pair<QHostAddress, int>> subnetList)

Sets subnetList as the whitelist of allowed subnets.

When the list is not empty, only IP addresses in this list will be allowed by QHttpServer. The whitelist takes priority over the blacklist.

Each subnet is represented as a pair consisting of:

• A base IP address of type QHostAddress.
• A CIDR prefix length of type int, which defines the subnet mask.

To allow only a specific IP address, use a prefix length of 32 for IPv4 (e.g., "192.168.1.100/32") or 128 for IPv6 (e.g., "2001:db8::1/128").

This function was introduced in Qt 6.10.

See also whitelist(), setBlacklist(), and QHostAddress::parseSubnet().

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

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

[since 6.10] QSpan<const std::pair<QHostAddress, int>> QHttpServerConfiguration::whitelist() const

Returns the whitelist of subnets allowed by QHttpServer.

This function was introduced in Qt 6.10.

See also setWhitelist().

[noexcept] QHttpServerConfiguration &QHttpServerConfiguration::operator=(QHttpServerConfiguration &&other)

Move-assigns other to this QHttpServerConfiguration.

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

Copy-assigns other to this QHttpServerConfiguration.
