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

const QString & | message = QString() , |

bool | requestCredentials = true |

) |
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 if requestCredentials is set to True.
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.

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.

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.
