## Detailed Description

The class defines the basic interface of the OAuth 2 authentication classes. By inheriting this class, you can create custom authentication methods using the OAuth 2 standard for different web services.

A description of how OAuth 2 works can be found in: The OAuth 2.0 Authorization Framework

## Property Documentation

### clientIdentifierSharedKey : QString

This property holds the client shared key used as a password if the server requires authentication to request the token.

Access functions:

QString | clientIdentifierSharedKey() const
void | setClientIdentifierSharedKey(const QString &clientIdentifierSharedKey)

Notifier signal:

void | clientIdentifierSharedKeyChanged(const QString &clientIdentifierSharedKey)

### expiration : const QDateTime

This property holds the expiration time of the current access token.

Access functions:

QDateTime | expirationAt() const

Notifier signal:

void | expirationAtChanged(const QDateTime &expiration)

### scope : QString

This property holds the desired scope which defines the permissions requested by the client.

Access functions:

QString | scope() const
void | setScope(const QString &scope)

Notifier signal:

void | scopeChanged(const QString &scope)

### state : QString

This property holds the string sent to the server during authentication. The state is used to identify and validate the request when the callback is received.

Access functions:

QString | state() const
void | setState(const QString &state)

Notifier signal:

void | stateChanged(const QString &state)

### userAgent : QString

This property holds the User-Agent header used to create the network requests.

The default value is "QtOAuth/1.0 (+https://www.qt.io)".

Access functions:

QString | userAgent() const
void | setUserAgent(const QString &userAgent)

Notifier signal:

void | userAgentChanged(const QString &userAgent)

## Member Function Documentation

### QAbstractOAuth2::QAbstractOAuth2(QNetworkAccessManager *manager, QObject *parent = nullptr)

Constructs a QAbstractOAuth2 object using parent as parent and sets manager as the network access manager.

### QAbstractOAuth2::QAbstractOAuth2(QObject *parent = nullptr)

Constructs a QAbstractOAuth2 object using parent as parent.

### `[signal]` void QAbstractOAuth2::authorizationCallbackReceived(const QVariantMap &data)

Signal emitted when the reply server receives the authorization callback from the server: data contains the values received from the server.

### `[signal]` void QAbstractOAuth2::error(const QString &error, const QString &errorDescription, const QUrl &uri)

Signal emitted when the server responds to the request with an error: error is the name of the error; errorDescription describes the error and uri is an optional URI containing more information about the error.

### `[virtual]` QAbstractOAuth2::~QAbstractOAuth2()

Destroys the QAbstractOAuth2 instance.

### `[virtual]` QUrl QAbstractOAuth2::createAuthenticatedUrl(const QUrl &url, const QVariantMap &parameters = QVariantMap())

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

This function was introduced in Qt 5.10.

See also post() and https://tools.ietf.org/html/rfc2616#section-9.6.

### `[virtual]` QNetworkReply *QAbstractOAuth2::post(const QUrl &url, QHttpMultiPart *multiPart)

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

This function was introduced in Qt 5.10.

See also post(), QHttpMultiPart, and https://tools.ietf.org/html/rfc2616#section-9.6.

### QString QAbstractOAuth2::refreshToken() const

Gets the current refresh token.

Refresh tokens usually have longer lifespans than access tokens, so it makes sense to save them for later use.

Returns the current refresh token or an empty string, if there is no refresh token available.

Note: Getter function for property refreshToken.

See also setRefreshToken().

### QString QAbstractOAuth2::responseType() const

Returns the response_type used.

### void QAbstractOAuth2::setRefreshToken(const QString &refreshToken)

Sets the new refresh token refreshToken to be used.

A custom refresh token can be used to refresh the access token via this method and then the access token can be refreshed via QOAuth2AuthorizationCodeFlow::refreshAccessToken().

Note: Setter function for property refreshToken.

See also refreshToken().
