## Detailed Description

The QAbstractOAuth2 class is the base of all implementations of OAuth 2 authentication methods.

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

### clientIdentifier : QString

This property holds the client identifier used to identify the application in the authentication process.

Access functions:

virtual QString | clientIdentifier() const override
virtual void | setClientIdentifier(const QString &clientIdentifier) override

Notifier signal:

void | clientIdentifierChanged(const QString &clientIdentifier)

### 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(QObject *parent = nullptr)

Constructs a QAbstractOAuth2 object using parent as parent.

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

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

### `[protected]` QAbstractOAuth2::QAbstractOAuth2(QAbstractOAuth2Private &, QObject *parent = nullptr)

Copy constructor.

### QAbstractOAuth2::~QAbstractOAuth2()

Destroys the QAbstractOAuth2 instance.

### `[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.

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

The returned URL is based on url, combining it with the given parameters and the access token.

### `[override virtual]` QNetworkReply *QAbstractOAuth2::deleteResource(const QUrl &url, const QVariantMap &parameters = QVariantMap())

Reimplemented from QAbstractOAuth::deleteResource().

Sends an authenticated DELETE request and returns a new QNetworkReply. The url and parameters are used to create the request.

See also: Hypertext Transfer Protocol -- HTTP/1.1: DELETE

### `[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.

### `[override virtual]` QNetworkReply *QAbstractOAuth2::get(const QUrl &url, const QVariantMap &parameters = QVariantMap())

Reimplemented from QAbstractOAuth::get().

Sends an authenticated GET request and returns a new QNetworkReply. The url and parameters are used to create the request.

See also: Hypertext Transfer Protocol -- HTTP/1.1: GET

### `[override virtual]` QNetworkReply *QAbstractOAuth2::head(const QUrl &url, const QVariantMap &parameters = QVariantMap())

Reimplemented from QAbstractOAuth::head().

Sends an authenticated HEAD request and returns a new QNetworkReply. The url and parameters are used to create the request.

See also: Hypertext Transfer Protocol -- HTTP/1.1: HEAD

### `[override virtual]` QNetworkReply *QAbstractOAuth2::post(const QUrl &url, const QVariantMap &parameters = QVariantMap())

Reimplemented from QAbstractOAuth::post().

Sends an authenticated POST request and returns a new QNetworkReply. The url and parameters are used to create the request.

See also: Hypertext Transfer Protocol -- HTTP/1.1: POST

### `[pure virtual]` QString QAbstractOAuth2::responseType() const

### `[override virtual]` void QAbstractOAuth2::setToken(const QString &token)

See also token().

### `[override virtual]` QString QAbstractOAuth2::token() const

See also setToken().
