class QgsServerOgcApiHandler
{
%Docstring(signature="appended")
The :py:class:`QgsServerOgcApiHandler` abstract class represents a OGC API handler to be registered
in :py:class:`QgsServerOgcApi` class.
Subclasses must override operational and informative methods and define
the core functionality in :py:func:`~handleRequest` method.
The following methods MUST be implemented:
- path
- operationId
- summary (shorter text)
- description (longer text)
- linkTitle
- linkType
- schema
Optionally, override:
- tags
- parameters
- contentTypes
- defaultContentType
.. code-block:: python
class Handler1(QgsServerOgcApiHandler):
"""Example handler"""
def path(self):
return QtCore.QRegularExpression("/handlerone")
def operationId(self):
return "handlerOne"
def summary(self):
return "First of its name"
def description(self):
return "The first handler ever"
def linkTitle(self):
return "Handler One Link Title"
def linkType(self):
return QgsServerOgcApi.data
def handleRequest(self, context):
"""Simple mirror: returns the parameters"""
params = self.values(context)
self.write(params, context)
def parameters(self, context):
return [QgsServerQueryStringParameter("value1", True, QgsServerQueryStringParameter.Type.Double, "a double value")]

public:
virtual ~QgsServerOgcApiHandler();
virtual QRegularExpression path() const = 0;
%Docstring
URL pattern for this handler, named capture group are automatically
extracted and returned by :py:func:`~QgsServerOgcApiHandler.values`
Example: "/handlername/(?P<code1>\d{2})/items" will capture "code1" as a
named parameter.
.. seealso:: :py:func:`values`
%End
virtual std::string operationId() const = 0;
%Docstring
Returns the operation id for template file names and other internal references
%End
virtual QList<QgsServerQueryStringParameter> parameters( const QgsServerApiContext &context ) const;
%Docstring
Returns a list of query string parameters.
Depending on the handler, it may be dynamic (per-request) or static.
:param context: the request context
%End
virtual std::string summary() const = 0;
%Docstring
Summary
%End
virtual std::string description() const = 0;
%Docstring
Description
%End
virtual std::string linkTitle() const = 0;
%Docstring
Title for the handler link
%End
virtual QgsServerOgcApi::Rel linkType() const = 0;
%Docstring
Main role for the resource link
%End
virtual QStringList tags() const;
%Docstring
Tags
%End
virtual QgsServerOgcApi::ContentType defaultContentType() const;
%Docstring
Returns the default response content type in case the client did not specifically
ask for any particular content type.
The default implementation returns the first content type returned by
:py:func:`~QgsServerOgcApiHandler.contentTypes` or JSON if that list is empty.
%End
virtual void handleRequest( const QgsServerApiContext &context ) const throw( QgsServerApiBadRequestException ) /VirtualErrorHandler=serverapi_badrequest_exception_handler/;
%Docstring
Handles the request within its ``context``
Subclasses must implement this methods, and call :py:func:`~QgsServerOgcApiHandler.validate` to
extract validated parameters from the request.
:raises QgsServerApiBadRequestError: if the method encounters any error
%End
virtual QVariantMap values( const QgsServerApiContext &context ) const throw( QgsServerApiBadRequestException );
%Docstring
Analyzes the incoming request ``context`` and returns the validated
parameter map, throws :py:class:`QgsServerApiBadRequestError` in case of errors.
Path fragments from the named groups in the :py:func:`~QgsServerOgcApiHandler.path` regular expression
are also added to the map.
Your handleRequest method should call this function to retrieve
the parameters map.
:return: the validated parameters map by extracting captured
named parameters from the path (no validation is performed on
the type because the regular expression can do it),
and the query string parameters.
.. seealso:: :py:func:`path`
.. seealso:: :py:func:`parameters`
:raises QgsServerApiBadRequestError: if validation fails
%End
QString contentTypeForAccept( const QString &accept ) const;
%Docstring
Looks for the first ContentType match in the accept header and returns its mime type,
returns an empty string if there are not matches.
%End
void write( QVariant &data, const QgsServerApiContext &context, const QVariantMap &htmlMetadata = QVariantMap() ) const throw( QgsServerApiBadRequestException );
%Docstring
Writes ``data`` to the ``context`` response stream, content-type is calculated from the ``context`` request,
optional ``htmlMetadata`` for the HTML templates can be specified and will be added as "metadata" to
the HTML template variables.
HTML output uses a template engine.
Available template functions:
See: https://github.com/pantor/inja#tutorial
Available custom template functions:
- path_append( path ): appends a directory path to the current url
- path_chomp( n ): removes the specified number "n" of directory components from the current url path
- :py:func:`~QgsServerOgcApiHandler.json_dump`: prints current JSON data passed to the template
- static( path): returns the full URL to the specified static path, for example:
static("/style/black.css") will return something like "/wfs3/static/style/black.css".
- links_filter( links, key, value ): returns filtered links from a link list
- content_type_name( content_type ): returns a short name from a content type for example "text/html" will return "HTML"
%End
std::string href( const QgsServerApiContext &context, const QString &extraPath = QString(), const QString &extension = QString() ) const;
%Docstring
Returns an URL to self, to be used for links to the current resources and as a base for constructing links to sub-resources
:param context: the current request context
:param extraPath: an optional extra path that will be appended to the calculated URL
:param extension: optional file extension to add (the dot will be added automatically).
%End
virtual const QString templatePath( const QgsServerApiContext &context ) const;
%Docstring
Returns the HTML template path for the handler in the given ``context``
The template path is calculated from :py:class:`QgsServerSettings`'s :py:func:`~QgsServerOgcApiHandler.apiResourcesDirectory` as follow:
:py:func:`~QgsServerOgcApiHandler.apiResourcesDirectory` + "/ogc/templates/" + context.apiRootPath + operationId + ".html"
e.g. for an API with root path "/wfs3" and an handler with operationId "collectionItems", the path
will be :py:func:`~QgsServerOgcApiHandler.apiResourcesDirectory` + "/ogc/templates/wfs3/collectionItems.html"
%End
virtual const QString staticPath( const QgsServerApiContext &context ) const;
%Docstring
Returns the absolute path to the base directory where static resources for
this handler are stored in the given ``context``.
%End
QgsServerOgcApi::ContentType contentTypeFromRequest( const QgsServerRequest *request ) const;
%Docstring
Returns the content type from the ``request``.
The path file extension is examined first and checked for known mime types,
the "Accept" HTTP header is examined next.
Fallback to the default content type of the handler if none of the above matches.
:raises QgsServerApiBadRequestError: if the content type of the request is not compatible with the handler (:py:func:`contentTypes` member)
%End
static QString parentLink( const QUrl &url, int levels = 1 );
%Docstring
Returns a link to the parent page up to ``levels`` in the HTML hierarchy from the given ``url``, MAP query argument is preserved
%End
static QgsVectorLayer *layerFromCollectionId( const QgsServerApiContext &context, const QString &collectionId );
%Docstring
Returns a vector layer from the ``collectionId`` in the given ``context``.
:raises QgsServerApiNotFoundError: if the layer could not be found.
%End
protected:
void setContentTypesInt( const QList<int> &contentTypes ) /PyName=setContentTypes/;
%Docstring
Set the content types to ``contentTypes``
%End
