Detailed Description

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

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

It also contains some functions to ease the process of implementing different authentication flows.

Member Type Documentation

enum QAbstractOAuth::ContentType

Indicates the MIME Content-Type of the POST methods in authenticated calls.

QAbstractOAuth::WwwFormUrlEncoded0Uses application/x-www-form-urlencoded format.
QAbstractOAuth::Json1Uses application/json format.

enum QAbstractOAuth::Error

Indicates the latest received error.

QAbstractOAuth::NoError0No error has ocurred.
QAbstractOAuth::NetworkError1Failed to connect to the server.
QAbstractOAuth::ServerError2The server answered the request with an error.
QAbstractOAuth::OAuthTokenNotFoundError3The server's response to a token request provided no token identifier.
QAbstractOAuth::OAuthTokenSecretNotFoundError4The server's response to a token request provided no token secret.
QAbstractOAuth::OAuthCallbackNotVerified5The authorization server has not verified the supplied callback URI in the request. This usually happens when the provided callback does not match with the callback supplied during client registration.

typedef QAbstractOAuth::ModifyParametersFunction

enum QAbstractOAuth::Stage

Identifies an authentication stage. It's passed to a ModifyParametersFunction so that it can make different changes to parameters at each call to it during the process of authentication.

QAbstractOAuth::RequestingTemporaryCredentials0Preparing the temporary credentials request.
QAbstractOAuth::RequestingAuthorization1Preparing the authorization grant URL.
QAbstractOAuth::RequestingAccessToken2Preparing the token request.
QAbstractOAuth::RefreshingAccessToken3Preparing the access token refresh.

enum QAbstractOAuth::Status

Indicates the current authentication status.

QAbstractOAuth::NotAuthenticated0No token has been retrieved.
QAbstractOAuth::TemporaryCredentialsReceived1Temporary credentials have been received, this status is used in some OAuth authetication methods.
QAbstractOAuth::Granted2Token credentials have been received and authenticated calls are allowed.
QAbstractOAuth::RefreshingToken3New token credentials have been requested.

Member Function Documentation

[protected] QAbstractOAuth::QAbstractOAuth(QAbstractOAuthPrivate &, QObject *parent = nullptr)

Copy constructor.

[virtual] QAbstractOAuth::~QAbstractOAuth()

Destroys the abstract OAuth.

QUrl QAbstractOAuth::authorizationUrl() const

Returns the authorization request URL.

Note: Getter function for property authorizationUrl.

See also setAuthorizationUrl().

[signal] void QAbstractOAuth::authorizeWithBrowser(const QUrl &url)

This signal is emitted when the url generated by resourceOwnerAuthorization() is ready to be used in the web browser to allow the application to impersonate the user.

See also resourceOwnerAuthorization().

[protected] QString QAbstractOAuth::callback() const

Returns the current callback string corresponding to the current reply handler. The returned string is the string sent to the server to specify the callback URI, or the word identifying the alternative method in headless devices.

See also replyHandler() and setReplyHandler().

[pure virtual] QString QAbstractOAuth::clientIdentifier() const

See also setClientIdentifier().

[signal] void QAbstractOAuth::clientIdentifierChanged(const QString &clientIdentifier)

ContentType QAbstractOAuth::contentType() const

Returns the current Content-Type used in authenticated calls.

Note: Getter function for property contentType.

See also setContentType() and post().

[pure virtual] QNetworkReply *QAbstractOAuth::deleteResource(const QUrl &url, const QVariantMap &parameters = QVariantMap())

Posts 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

QVariantMap QAbstractOAuth::extraTokens() const

Returns the extra tokens received from the server during authentication.

Note: Getter function for property extraTokens.

See also extraTokensChanged().

[signal] void QAbstractOAuth::finished(QNetworkReply *reply)

[static protected] QByteArray QAbstractOAuth::generateRandomString(quint8 length)

Generates a random string which could be used as state or nonce. The parameter length determines the size of the generated string.

See also: The OAuth 1.0 Protocol: Nonce and Timestamp.

[pure virtual] QNetworkReply *QAbstractOAuth::get(const QUrl &url, const QVariantMap &parameters = QVariantMap())

Posts 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

[pure virtual slot] void QAbstractOAuth::grant()

Override this function to implement the corresponding authentication flow in the subclasses. Client code calls this function to start the authentication workflow. This may require user interaction: for example, asking the user's authorization via a web browser. When the authentication succeeds, it should emit granted(); this gives notice that credentials are ready to be used in authenticated calls.

[signal] void QAbstractOAuth::granted()

This signal is emitted when the authorization flow finishes successfully.

Posts 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

ModifyParametersFunction QAbstractOAuth::modifyParametersFunction() const

Returns the current parameter-modification function.

See also ModifyParametersFunction, setModifyParametersFunction(), and Stage.

QNetworkAccessManager *QAbstractOAuth::networkAccessManager() const

Returns the current network access manager used to send the requests to the server during authentication flows or to make authentication calls.

See also setNetworkAccessManager() and QNetworkAccessManager.

[pure virtual] QNetworkReply *QAbstractOAuth::post(const QUrl &url, const QVariantMap &parameters = QVariantMap())

Posts 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

[signal] void QAbstractOAuth::replyDataReceived(const QByteArray &data)

QAbstractOAuthReplyHandler *QAbstractOAuth::replyHandler() const

Returns the reply handler currently in use.

See also setReplyHandler() and QAbstractOAuthReplyHandler.

[signal] void QAbstractOAuth::requestFailed(const Error error)

[virtual protected] void QAbstractOAuth::resourceOwnerAuthorization(const QUrl &url, const QVariantMap &parameters)

Builds the resource owner authorization URL to be used in the web browser: url is used as the base URL and the query is created using parameters. When the URL is ready, the authorizeWithBrowser() signal will be emitted with the generated URL.

See also authorizeWithBrowser().

void QAbstractOAuth::setAuthorizationUrl(const QUrl &url)

Sets the authorization request URL to url. This address will be used to allow the user to grant the application the ability to make authenticated calls on behalf of the user.

Note: Setter function for property authorizationUrl.

See also authorizationUrl().

[pure virtual] void QAbstractOAuth::setClientIdentifier(const QString &clientIdentifier)

See also clientIdentifier().

void QAbstractOAuth::setContentType(ContentType contentType)

Sets the current Content-Type to contentType.

Note: Setter function for property contentType.

See also contentType().

void QAbstractOAuth::setModifyParametersFunction(const ModifyParametersFunction &modifyParametersFunction)

See also modifyParametersFunction().

void QAbstractOAuth::setNetworkAccessManager(QNetworkAccessManager *networkAccessManager)

Sets the network manager to networkAccessManager. QAbstractOAuth does not take ownership of networkAccessManager. If no custom network access manager is set, an internal network access manager is used. This network access manager will be used to make the request to the authentication server and the authenticated request to the web service.

See also networkAccessManager() and QNetworkAccessManager.

void QAbstractOAuth::setReplyHandler(QAbstractOAuthReplyHandler *handler)

Sets the current reply handler to handler.

Note: Does not take ownership of handler.

See also replyHandler().

Sets the current status to status. This method is for use by classes based on QAbstractOAuth.

See also status().

[pure virtual] void QAbstractOAuth::setToken(const QString &token)

See also token().

Status QAbstractOAuth::status() const

Returns the current authentication status.

Note: Getter function for property status.

See also setStatus() and Status.

[pure virtual] QString QAbstractOAuth::token() const

See also setToken().

[signal] void QAbstractOAuth::tokenChanged(const QString &token)
