Detailed Description

Interface for requesting credentials in QGIS in GUI independent way.

This class provides abstraction of a dialog for requesting credentials to the user. By default QgsCredentials will be used if not overridden with other credential creator function.

QGIS application uses QgsCredentialDialog class for displaying a dialog to the user.

Caller can use the mutex to synchronize authentications to avoid requesting credentials for the same resource several times.

Object deletes itself when it's not needed anymore. Children should use signal destroyed() to be notified of the deletion

Constructor & Destructor Documentation

◆ ~QgsCredentials()

virtual QgsCredentials::~QgsCredentials ( )

virtualdefault

Destructor.

◆ QgsCredentials()

QgsCredentials::QgsCredentials ( )

protecteddefault

Constructor for QgsCredentials.

Member Function Documentation

◆ get()

bool QgsCredentials::get	(	const QString &	realm,
		QString &	username,
		QString &	password,
		const QString &	message = `QString()`
	)

Requests credentials for the specified realm.

If existing credentials exist for the given realm, these will be returned. Otherwise the credential handler will prompt for the correct username and password.

The retrieved or user-entered details will be stored in username and password.

Optionally, a specific message can be used to advise users of the context for the credentials request.

Note: This method will not automatically store the newly obtained credentials. Callers must manually call put() after verifying that the obtained credentials are correct.

◆ getMasterPassword()

bool QgsCredentials::getMasterPassword	(	QString &	password,
		bool	stored = `false`
	)

Definition at line 77 of file qgscredentials.cpp.

◆ instance()

QgsCredentials * QgsCredentials::instance ( )

static

retrieves instance

Definition at line 34 of file qgscredentials.cpp.

◆ lock()

void QgsCredentials::lock ( )

Lock the instance against access from multiple threads.

This does not really lock access to get/put methods, it will just prevent other threads to lock the instance and continue the execution. When the class is used from non-GUI threads, they should call lock() before the get/put calls to avoid race conditions.

Since: QGIS 2.4

Definition at line 87 of file qgscredentials.cpp.

◆ mutex()

QMutex * QgsCredentials::mutex ( )

inline

Returns pointer to mutex.

Since: QGIS 2.4

Definition at line 105 of file qgscredentials.h.

◆ put()

void QgsCredentials::put	(	const QString &	realm,
		const QString &	username,
		const QString &	password
	)

Stores the correct username and password for the specified realm.

These values will be used for all future calls to get() for the same realm, without requesting users to re-enter them. It is the caller's responsibility to ensure that only valid username and password combinations are used with this method.

◆ request()

virtual bool QgsCredentials::request	(	const QString &	realm,
		QString &	username,
		QString &	password,
		const QString &	message = `QString()`
	)

protectedpure virtual

request a password

Implemented in QgsCredentialsNone, QgsCredentialsConsole, and QgsCredentialDialog.

◆ requestMasterPassword()

virtual bool QgsCredentials::requestMasterPassword	(	QString &	password,
		bool	stored = `false`
	)

protectedpure virtual

request a master password

Implemented in QgsCredentialsNone, QgsCredentialsConsole, and QgsCredentialDialog.

◆ setInstance()

void QgsCredentials::setInstance ( QgsCredentials * instance )

protected

register instance

Definition at line 24 of file qgscredentials.cpp.

◆ unlock()

void QgsCredentials::unlock ( )

Unlock the instance after being locked.
