Class: QgsServerFilter¶

Class defining I/O filters for QGIS Server and implemented in plugins.

Methods

`onProjectReady`	Method called when the `QgsProject` instance is ready to be used to perform the request, just before entering the main switch for core services.
`onRequestReady`	Method called when the `QgsRequestHandler` is ready and populated with parameters, just before entering the main switch for core services.
`onResponseComplete`	Method called when the `QgsRequestHandler` processing has done and the response is ready, just after the main switch for core services and before final sending response to FCGI stdout.
`onSendResponse`	Method called when the `QgsRequestHandler` sends its data to FCGI stdout.
`requestReady`	Method called when the `QgsRequestHandler` is ready and populated with parameters, just before entering the main switch for core services.
`responseComplete`	Method called when the `QgsRequestHandler` processing has done and the response is ready, just after the main switch for core services and before final sending response.
`sendResponse`	Method called when the `QgsRequestHandler` sends its data to FCGI stdout.
`serverInterface`	Returns the `QgsServerInterface` instance

class qgis.server.QgsServerFilter[source]¶

Bases: object

__init__(serverInterface: QgsServerInterface | None)

Constructor QgsServerInterface passed to plugins constructors and must be passed to QgsServerFilter instances.

Parameters:: serverInterface (Optional[QgsServerInterface])

__init__(a0: QgsServerFilter)

Parameters:: a0 (QgsServerFilter)

onProjectReady(self) → bool[source]¶

Method called when the QgsProject instance is ready to be used to perform the request, just before entering the main switch for core services.

Return type:: bool
Returns:: true if the call must propagate to the subsequent filters, false otherwise

Added in version 3.36.

onRequestReady(self) → bool[source]¶

Method called when the QgsRequestHandler is ready and populated with parameters, just before entering the main switch for core services.

Return type:: bool
Returns:: true if the call must propagate to the subsequent filters, false otherwise

Added in version 3.24.

onResponseComplete(self) → bool[source]¶

Method called when the QgsRequestHandler processing has done and the response is ready, just after the main switch for core services and before final sending response to FCGI stdout.

Return type:: bool
Returns:: true if the call must propagate to the subsequent filters, false otherwise

Added in version 3.24.

onSendResponse(self) → bool[source]¶

Method called when the QgsRequestHandler sends its data to FCGI stdout. This normally occurs at the end of core services processing just after the responseComplete() plugin hook. For streaming services (like WFS on getFeature requests, sendResponse() might have been called several times before the response is complete: in this particular case, sendResponse() is called once for each feature before hitting responseComplete()

Return type:: bool
Returns:: true if the call must propagate to the subsequent filters, false otherwise

Added in version 3.22.

requestReady(self)[source]¶

Method called when the QgsRequestHandler is ready and populated with parameters, just before entering the main switch for core services.

This method is considered as deprecated and onRequestReady() should be used instead.

Deprecated since version 3.40: Will be removed in QGIS 4.0.

responseComplete(self)[source]¶

Method called when the QgsRequestHandler processing has done and the response is ready, just after the main switch for core services and before final sending response.

This method is considered as deprecated and onResponseComplete() should be used instead.

Deprecated since version 3.40: Will be removed in QGIS 4.0.

sendResponse(self)[source]¶

Method called when the QgsRequestHandler sends its data to FCGI stdout. This normally occurs at the end of core services processing just after the responseComplete() plugin hook. For streaming services (like WFS on getFeature requests, sendResponse() might have been called several times before the response is complete: in this particular case, sendResponse() is called once for each feature before hitting responseComplete()

This method is considered as deprecated and onSendResponse() should be used instead.

Deprecated since version 3.40: Will be removed in QGIS 4.0.

serverInterface(self) → QgsServerInterface | None[source]¶

Returns the QgsServerInterface instance

Return type:: Optional[QgsServerInterface]
