QNetworkRequestFactory Class

Member Function Documentation

QNetworkRequestFactory::QNetworkRequestFactory()

Creates a new QNetworkRequestFactory object. Use setBaseUrl() to set a valid base URL for the requests.

See also QNetworkRequestFactory(const QUrl &baseUrl) and setBaseUrl().

[explicit] QNetworkRequestFactory::QNetworkRequestFactory(const QUrl &baseUrl)

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

QNetworkRequestFactory::QNetworkRequestFactory(const QNetworkRequestFactory &other)

Creates a copy of other.

[noexcept] QNetworkRequestFactory::QNetworkRequestFactory(QNetworkRequestFactory &&other)

Move-constructs the factory from other.

[noexcept] QNetworkRequestFactory::~QNetworkRequestFactory()

Destroys this QNetworkRequestFactory object.

[since 6.8] QVariant QNetworkRequestFactory::attribute(QNetworkRequest::Attribute attribute) const

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

This function was introduced in Qt 6.8.

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

[since 6.8] QVariant QNetworkRequestFactory::attribute(QNetworkRequest::Attribute attribute, const QVariant &defaultValue) const

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

This function was introduced in Qt 6.8.

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

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().

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 commonHeaders() listing. If the commonHeaders() also lists Authorization header, it will be overwritten.

See also setBearerToken() and commonHeaders().

[since 6.8] void QNetworkRequestFactory::clearAttribute(QNetworkRequest::Attribute attribute)

Clears attribute set to this factory.

This function was introduced in Qt 6.8.

See also attribute() and setAttribute().

[since 6.8] void QNetworkRequestFactory::clearAttributes()

Clears any attributes set to this factory.

This function was introduced in Qt 6.8.

See also attribute() and setAttribute().

void QNetworkRequestFactory::clearBearerToken()

Clears the bearer token.

See also bearerToken().

void QNetworkRequestFactory::clearCommonHeaders()

Clears current headers.

See also commonHeaders() and setCommonHeaders().

void QNetworkRequestFactory::clearPassword()

Clears the password set to this factory.

See also password(), setPassword(), and userName().

void QNetworkRequestFactory::clearQueryParameters()

Clears the query parameters.

See also queryParameters().

void QNetworkRequestFactory::clearUserName()

Clears the username set to this factory.

QHttpHeaders QNetworkRequestFactory::commonHeaders() const

Returns the currently set headers.

See also setCommonHeaders() and clearCommonHeaders().

QNetworkRequest QNetworkRequestFactory::createRequest() const

Returns a QNetworkRequest.

The returned request is filled with the data that this factory has been configured with.

See also createRequest(const QUrlQuery&) and createRequest(const QString&, const QUrlQuery&).

QNetworkRequest QNetworkRequestFactory::createRequest(const QString &path) const

Returns a QNetworkRequest.

The returned request's URL is formed by appending the provided path to the baseUrl (which may itself have a path component).

See also createRequest(const QString &, const QUrlQuery &), createRequest(), and baseUrl().

QNetworkRequest QNetworkRequestFactory::createRequest(const QUrlQuery &query) const

Returns a QNetworkRequest.

The returned request's URL is formed by appending the provided query to the baseUrl.

See also createRequest(const QString &, const QUrlQuery &), createRequest(), and baseUrl().

QNetworkRequest QNetworkRequestFactory::createRequest(const QString &path, const QUrlQuery &query) const

Returns a QNetworkRequest.

The returned requests URL is formed by appending the provided path and query to the baseUrl (which may have a path component).

If the provided path contains query items, they will be combined with the items in query.

See also createRequest(const QUrlQuery&), createRequest(), and baseUrl().

QString QNetworkRequestFactory::password() const

Returns the password set to this factory.

See also setPassword(), password(), clearPassword(), and userName().

[since 6.8] QNetworkRequest::Priority QNetworkRequestFactory::priority() const

Returns the priority assigned to any future requests created by this factory.

This function was introduced in Qt 6.8.

See also setPriority() and QNetworkRequest::priority().

QUrlQuery QNetworkRequestFactory::queryParameters() const

Returns query parameters that are added to individual requests' query parameters. The query parameters are added to any potential query parameters provided with the individual createRequest() calls.

Use cases for using repeating query parameters are server dependent, but typical examples include language setting ?lang=en, format specification ?format=json, API version specification ?version=1.0 and API key authentication.

See also setQueryParameters(), clearQueryParameters(), and createRequest().

[since 6.8] void QNetworkRequestFactory::setAttribute(QNetworkRequest::Attribute attribute, const QVariant &value)

Sets the value associated with attribute to value. If the attribute is already set, the previous value is replaced. The attributes are set to any future requests created by this factory.

This function was introduced in Qt 6.8.

See also attribute(), clearAttribute(), clearAttributes(), and QNetworkRequest::Attribute.

void QNetworkRequestFactory::setBaseUrl(const QUrl &url)

Sets the base URL used in individual requests to url.

See also baseUrl().

void QNetworkRequestFactory::setBearerToken(const QByteArray &token)

Sets the bearer token to token.

See also bearerToken() and clearBearerToken().

void QNetworkRequestFactory::setCommonHeaders(const QHttpHeaders &headers)

Sets headers that are common to all requests.

These headers are added to individual requests' headers. This is a convenience mechanism for setting headers that repeat across requests.

See also commonHeaders(), clearCommonHeaders(), and createRequest().

void QNetworkRequestFactory::setPassword(const QString &password)

Sets the password of this factory to password.

The password is set in the request URL when createRequest() is called. The QRestAccessManager / QNetworkAccessManager will attempt to use these credentials when the server indicates that authentication is required.

See also password(), clearPassword(), and userName().

[since 6.8] void QNetworkRequestFactory::setPriority(QNetworkRequest::Priority priority)
