Detailed Description

The QHstsPolicy class specifies that a host supports HTTP Strict Transport Security policy (HSTS).

HSTS policy defines a period of time during which QNetworkAccessManager should only access a host in a secure fashion. HSTS policy is defined by RFC6797.

You can set expiry time and host name for this policy, and control whether it applies to subdomains, either in the constructor or by calling setExpiry(), setHost() and setIncludesSubdomains().

See also QNetworkAccessManager::setStrictTransportSecurityEnabled().

Member Type Documentation

enum QHstsPolicy::PolicyFlag
flags QHstsPolicy::PolicyFlags

Constant Value Description
QHstsPolicy::IncludeSubDomains 1 Indicates whether a policy must include subdomains

The PolicyFlags type is a typedef for QFlags<PolicyFlag>. It stores an OR combination of PolicyFlag values.

Member Function Documentation


Constructs an invalid (expired) policy with empty host name and subdomains not included.

QHstsPolicy::QHstsPolicy(const QDateTime &expiry, QHstsPolicy::PolicyFlags flags, const QString &host, QUrl::ParsingMode mode = QUrl::DecodedMode)

Constructs QHstsPolicy with expiry (in UTC); flags is a value indicating whether this policy must also include subdomains, host data is interpreted according to mode.

See also QUrl::setHost(), QUrl::ParsingMode, and QHstsPolicy::PolicyFlag.

QHstsPolicy::QHstsPolicy(const QHstsPolicy &other)

Creates a copy of other object.



QDateTime QHstsPolicy::expiry() const

Returns the expiration date for the policy (in UTC).

See also setExpiry().

QString QHstsPolicy::host(QUrl::ComponentFormattingOptions options) const

Returns a host for a given policy, formatted according to options.

See also setHost(), QUrl::host(), and QUrl::ComponentFormattingOptions.

bool QHstsPolicy::includesSubDomains() const

Returns true if this policy also includes subdomains.

See also setIncludesSubDomains().

bool QHstsPolicy::isExpired() const

Return true if this policy has a valid expiration date and this date is greater than QDateTime::currentGetDateTimeUtc().

See also setExpiry() and expiry().

void QHstsPolicy::setExpiry(const QDateTime &expiry)

Sets the expiration date for the policy (in UTC) to expiry.

See also expiry().

void QHstsPolicy::setHost(const QString &host, QUrl::ParsingMode mode = QUrl::DecodedMode)

Sets a host, host data is interpreted according to mode parameter.

See also host(), QUrl::setHost(), and QUrl::ParsingMode.

void QHstsPolicy::setIncludesSubDomains(bool include)

Sets whether subdomains are included for this policy to include.

See also includesSubDomains().

void QHstsPolicy::swap(QHstsPolicy &other)

Swaps this policy with the other policy.

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

Copy-assignment operator, makes a copy of other.

QHstsPolicy &QHstsPolicy::operator=(QHstsPolicy &&other)

Move-assignment operator.
