詳細描述

QAuthenticator 類通常用於 authenticationRequired() and proxyAuthenticationRequired() 信號對於 QNetworkAccessManager and QAbstractSocket . The class provides a way to pass back the required authentication information to the socket when accessing services that require authentication.

QAuthenticator 支持下列身份驗證方法：

基本
NTLM version 2
Digest-MD5
SPNEGO/Negotiate

選項

In addition to the username and password required for authentication, a QAuthenticator object can also contain additional options. The options () function can be used to query incoming options sent by the server; the setOption () function can be used to set outgoing options, to be processed by the authenticator calculation. The options accepted and provided depend on the authentication type (see method()).

The following tables list known incoming options as well as accepted outgoing options. The list of incoming options is not exhaustive, since servers may include additional information at any time. The list of outgoing options is exhaustive, however, and no unknown options will be treated or sent back to the server.

基本

選項	方嚮	類型	描述
`realm`	傳入	QString	Contains the realm of the authentication, the same as realm ()

The Basic authentication mechanism supports no outgoing options.

NTLM version 2

The NTLM authentication mechanism currently supports no incoming or outgoing options. On Windows, if no user has been set, domain\user credentials will be searched for on the local system to enable Single-Sign-On functionality.

Digest-MD5

選項	方嚮	類型	描述
`realm`	傳入	QString	Contains the realm of the authentication, the same as realm ()

The Digest-MD5 authentication mechanism supports no outgoing options.

SPNEGO/Negotiate

This authentication mechanism currently supports no incoming or outgoing options.

QAuthenticator:: QAuthenticator (const QAuthenticator & other )

構造副本為 other .

QAuthenticator:: QAuthenticator ()

構造空身份驗證對象。

QAuthenticator &QAuthenticator:: operator= (const QAuthenticator & other )

賦值內容對於 other to this authenticator.

QAuthenticator:: ~QAuthenticator ()

銷毀對象。

bool QAuthenticator:: isNull () const

返迴 true if the object has not been initialized. Returns false if non-const member functions have been called, or the content was constructed or copied from another initialized QAuthenticator 對象。

QVariant QAuthenticator:: option (const QString & opt ) const

Returns the value related to option opt if it was set by the server. See the Options section for more information on incoming options. If option opt isn't found, an invalid QVariant 將被返迴。

該函數在 Qt 4.7 引入。

另請參閱 setOption (), options ()，和 QAuthenticator options .

QVariantHash QAuthenticator:: options () const

Returns all incoming options set in this QAuthenticator object by parsing the server reply. See the Options section for more information on incoming options.

該函數在 Qt 4.7 引入。
