displayDescription	Translatable display version of the 'description()'
editWidget	Constructs the configuration for the authentication method

class qgis.core.QgsAuthMethod

Bases: QObject

__init__()

Construct a default authentication method

Note

Non-public since this is an abstract base class

All = 31

DataSourceUri = 4

class Expansion

Bases: int

class Expansions

class Expansions(f: QgsAuthMethod.Expansions | QgsAuthMethod.Expansion)

class Expansions(a0: QgsAuthMethod.Expansions)

Bases: object

GenericDataSourceUri = 8

NetworkProxy = 22

NetworkReply = 2

NetworkRequest = 1

static authMethodTag() → str

Tag signifying that this is an authentcation method (e.g. for use as title in message log panel output)

Return type:

str

clearCachedConfig(self, authcfg: str | None)

Clear any cached configuration. Called when the QgsAuthManager deletes an authentication configuration (authcfg).

Note

It is highly recommended that a cache of authentication components (per requested authcfg) be implemented, to avoid excessive queries on the auth database. Such a cache could be as simple as a QHash or QMap of authcfg -> QgsAuthMethodConfig. See ‘Basic’ auth method plugin for example.

Parameters:

authcfg (Optional[str])

description(self) → str

A non-translated short description representing the auth method for use in debug output and About dialog

Return type:

str

displayDescription(self) → str

Translatable display version of the ‘description()’

Return type:

str

editWidget(self, parent: QWidget | None) → QWidget | None

Constructs the configuration for the authentication method

Added in version 3.22.

Parameters:

parent (Optional[QWidget])

Return type:

Optional[QWidget]

key(self) → str

A non-translated short name representing the auth method

Return type:

str

setDataProviders(self, dataproviders: Iterable[str | None])

Sets list of data providers this auth method supports

Parameters:

dataproviders (Iterable[Optional[str]])

setExpansions(self, expansions: QgsAuthMethod.Expansions | QgsAuthMethod.Expansion)

Sets the support expansions (points in providers where the authentication is injected) of the auth method

Parameters:

expansions (Union[QgsAuthMethod.Expansions, QgsAuthMethod.Expansion])

setVersion(self, version: int)

Sets the version of the auth method (useful for future upgrading)

Parameters:

version (int)

supportedDataProviders(self) → List[str]

The data providers that the method supports, allowing for filtering out authcfgs that are not applicable to a given provider, or where the updating code is not currently implemented.

Return type:

List[str]

supportedExpansions(self) → QgsAuthMethod.Expansions

Flags that represent the update points (where authentication configurations are expanded) supported by an authentication method.

Note

These should directly correlate to existing ‘update*()’ member functions

Return type:

QgsAuthMethod.Expansions

updateDataSourceUriItems(self, connectionItems: Iterable[str | None], authcfg: str | None, dataprovider: str | None = '') → bool

Update data source connection items with authentication components

Parameters:

• connectionItems (Iterable[Optional[str]]) – QStringlist of ‘key=value’ pairs, as utilized in QgsDataSourceUri.connectionInfo()

• authcfg (Optional[str]) – Authentication configuration ID

• dataprovider (Optional[str] = '') – Textual key for a data provider, e.g. ‘postgres’, that allows for custom updater code specific to the provider

Return type:

bool

Returns:

Whether the update succeeded

updateMethodConfig(self, mconfig: QgsAuthMethodConfig)

Update an authentication configuration in place

Note

Useful for updating previously stored authcfgs, when an authentication method has been significantly updated

Parameters:

mconfig (QgsAuthMethodConfig)

updateNetworkProxy(self, proxy: QNetworkProxy, authcfg: str | None, dataprovider: str | None = '') → bool

Update proxy settings with authentication components

Parameters:

• proxy (QNetworkProxy)

• authcfg (Optional[str]) – Authentication configuration ID

• dataprovider (Optional[str] = '') – Textual key for a data provider, e.g. ‘proxy’, that allows for custom updater code specific to the provider

Return type:

bool

Returns:

Whether the update succeeded

updateNetworkReply(self, reply: QNetworkReply | None, authcfg: str | None, dataprovider: str | None = '') → bool

Update a network reply with authentication components

Parameters:

• reply (Optional[QNetworkReply]) – The network reply object to update

• authcfg (Optional[str]) – Authentication configuration ID

• dataprovider (Optional[str] = '') – Textual key for a data provider, e.g. ‘postgres’, that allows for custom updater code specific to the provider

Return type:

bool

Returns:

Whether the update succeeded

updateNetworkRequest(self, request: QNetworkRequest, authcfg: str | None, dataprovider: str | None = '') → bool

Update a network request with authentication components

Parameters:

• request (QNetworkRequest) – The network request to update

• authcfg (Optional[str]) – Authentication configuration ID

• dataprovider (Optional[str] = '') – Textual key for a data provider, e.g. ‘postgres’, that allows for custom updater code specific to the provider

Return type:

bool

Returns:

Whether the update succeeded

version(self) → int

Increment this if method is significantly updated, allow updater code to be written for previously stored authcfg

Return type:

int
