Detailed Description

Convenience class for grouping remote server endpoints that share common network request properties.

Since: 6.7

\inmodule QtNetwork

\preliminary

REST servers often have endpoints that require the same headers and other data. Grouping such endpoints with a QNetworkRequestFactory makes it more convenient to issue requests to these endpoints; only the typically varying parts such as path and query parameters are provided when creating a new request.

Basic usage steps of QNetworkRequestFactory are as follows: \list

Instantiation
Setting the data common to all requests
Issuing requests \endlist

An example of usage:

// Instantiate a factory somewhere suitable in the application
QNetworkRequestFactory api{{"https://example.com/v1"_L1}};
 
// Set bearer token
api.setBearerToken("my_token");
 
// Issue requests (reply handling omitted for brevity)
manager.get(api.createRequest("models"_L1)); // https://example.com/v1/models
// The conventional leading '/' for the path can be used as well
manager.get(api.createRequest("/models"_L1)); // https://example.com/v1/models

Constructor & Destructor Documentation

◆ QNetworkRequestFactory() [1/4]

QNetworkRequestFactory::QNetworkRequestFactory ( )

Creates a new QNetworkRequestFactory object.

Use setBaseUrl() to set a valid base URL for the requests.

See also: QNetworkRequestFactory(const QUrl &baseUrl), setBaseUrl()

Definition at line 58 of file qnetworkrequestfactory.cpp.

◆ QNetworkRequestFactory() [2/4]

QNetworkRequestFactory::QNetworkRequestFactory ( const QUrl & baseUrl )

explicit

Creates a new QNetworkRequestFactory object, initializing the base URL to baseUrl.

The base URL is used to populate subsequent network requests.

If the URL contains a path component, it will be extracted and used as a base path in subsequent network requests. This means that any paths provided when requesting individual requests will be appended to this base path, as illustrated below:

// Here the API version v2 is used as the base path:
QNetworkRequestFactory api{{"https://example.com/v2"_L1}};
// ...
manager.get(api.createRequest("models"_L1)); // https://example.com/v2/models
// Equivalent with a leading '/'
manager.get(api.createRequest("/models"_L1)); // https://example.com/v2/models

Definition at line 75 of file qnetworkrequestfactory.cpp.

◆ ~QNetworkRequestFactory()

QNetworkRequestFactory::~QNetworkRequestFactory ( )

default

Destroys this QNetworkRequestFactory object.

◆ QNetworkRequestFactory() [3/4]

QNetworkRequestFactory::QNetworkRequestFactory ( const QNetworkRequestFactory & other )

default

Creates a copy of other.

◆ QNetworkRequestFactory() [4/4]

QNetworkRequestFactory::QNetworkRequestFactory ( QNetworkRequestFactory && other )

defaultnoexcept

Move-constructs the factory from other.

Note: The moved-from object other is placed in a partially-formed state, in which the only valid operations are destruction and assignment of a new value.

Member Function Documentation

◆ attribute() [1/2]

QVariant QNetworkRequestFactory::attribute ( QNetworkRequest::Attribute attribute ) const

Since: 6.8

Returns the value associated with attribute. If the attribute has not been set, returns a default-constructed \l QVariant.

See also: attribute(QNetworkRequest::Attribute, const QVariant &), setAttribute(), clearAttributes(), QNetworkRequest::Attribute

Definition at line 549 of file qnetworkrequestfactory.cpp.

Here is the call graph for this function:

◆ attribute() [2/2]

QVariant QNetworkRequestFactory::attribute	(	QNetworkRequest::Attribute	attribute,
		const QVariant &	defaultValue ) const

Since: 6.8

Returns the value associated with attribute. If the attribute has not been set, returns defaultValue.

See also: attribute(), setAttribute(), clearAttributes(), QNetworkRequest::Attribute

Definition at line 563 of file qnetworkrequestfactory.cpp.

References QNetworkRequestFactoryPrivate::attributes, and QHash< Key, T >::value().

Here is the call graph for this function:

◆ baseUrl()

QUrl QNetworkRequestFactory::baseUrl ( ) const

Returns the base URL used for the individual requests.

The base URL may contain a path component. This path is used as path "prefix" for the paths that are provided when generating individual requests.

See also: setBaseUrl()

Definition at line 134 of file qnetworkrequestfactory.cpp.

References QNetworkRequestFactoryPrivate::baseUrl.

◆ bearerToken()

QByteArray QNetworkRequestFactory::bearerToken ( ) const

Returns the bearer token that has been set.

The bearer token, if present, is used to set the {Authorization: Bearer my_token} header for requests. This is a common authorization convention and is provided as an additional convenience.

The means to acquire the bearer token vary. Standard methods include OAuth2 and the service provider's website/dashboard. It is expected that the bearer token changes over time. For example, when updated with a refresh token, always setting the new token again ensures that subsequent requests have the latest, valid token.

The presence of the bearer token does not impact the \l commonHeaders() listing. If the \l commonHeaders() also lists Authorization header, it will be overwritten.
