对于使用 QT 的 networkauth 和新的 QOAuth2AuthorizationCodeFlow 对象的 OAuth 2.0，如何设置 redirect_uri？我的代码如下。它会导致发送以下身份验证 url:

QOAuth2AuthorizationCodeFlow::buildAuthenticateUrl: https://accounts.google.com/o/oauth2/auth?client_id=123-abc.apps.googleusercontent.com&redirect_uri=http://localhost:65535/cb&response_type=code&scope=email&state=iEIYn5sN

将 redirect_uri 设置为“http://localhost”，会导致来自谷歌的错误 400 redirect_uri_mismatch，这显然需要提供实际的重定向主机名。

GoogleGateway::GoogleGateway() {

auto google = new QOAuth2AuthorizationCodeFlow;
google->setScope("email");

this->connect(google, &QOAuth2AuthorizationCodeFlow::authorizeWithBrowser, &QDesktopServices::openUrl);

QString val;
QFile file;
file.setFileName("/home/me/client_secret.json");
file.open(QIODevice::ReadOnly | QIODevice::Text);
val = file.readAll();
file.close();

QJsonDocument document = QJsonDocument::fromJson(val.toUtf8());
QJsonObject object = document.object();
const auto settingsObject = object["web"].toObject();
const QUrl authUri(settingsObject["auth_uri"].toString());
const auto clientId = settingsObject["client_id"].toString();
const QUrl tokenUri(settingsObject["token_uri"].toString());
const auto clientSecret(settingsObject["client_secret"].toString());
const auto redirectUris = settingsObject["redirect_uris"].toArray();
const QUrl redirectUri(redirectUris[0].toString());
const auto port = static_cast<quint16>(redirectUri.port());

google->setAuthorizationUrl(authUri);
google->setClientIdentifier(clientId);
google->setAccessTokenUrl(tokenUri);
google->setClientIdentifierSharedKey(clientSecret);

auto replyHandler = new QOAuthHttpServerReplyHandler(port, this);
google->setReplyHandler(replyHandler);

google->grant();
}

要设置 redirect_uri，我尝试替换:

auto replyHandler = new QOAuthHttpServerReplyHandler(port, this);

与

QHostAddress hostaddress = QHostAddress(quint32(1233...));
auto replyHandler = new QOAuthHttpServerReplyHandler(hostaddress, port, this);

结果没有变化。

也试过插入:

replyHandler->setProperty("redirect_uri", "http://abc.xyz.com:65535/cb");

结果也没有变化。

在Qt/5.8/Src/qtnetworkauth/src/oauth/qoauthhttpserverreplyhandler.cpp中，我们看到回调地址看起来是硬编码的:

QString QOAuthHttpServerReplyHandler::callback() const
{
    Q_D(const QOAuthHttpServerReplyHandler);

    Q_ASSERT(d->httpServer.isListening());
    const QUrl url(QString::fromLatin1("http://localhost:%1/cb").arg(d->httpServer.serverPort()));
    return url.toString(QUrl::EncodeDelimiters);
}

这个callback()又在Qt/5.8/Src/qtnetworkauth/src/oauth/qoauth2authorizationcodeflow.cpp中使用来设置redirectUri值:

QUrl QOAuth2AuthorizationCodeFlow::buildAuthenticateUrl(const QVariantMap &parameters)
{
    Q_D(QOAuth2AuthorizationCodeFlow);
    using Key = QAbstractOAuth2Private::OAuth2KeyString;

    if (d->state.isEmpty())
        setState(QAbstractOAuth2Private::generateRandomState());
    Q_ASSERT(!d->state.isEmpty());
    const QString state = d->state;

    QVariantMap p(parameters);
    QUrl url(d->authorizationUrl);
    p.insert(Key::responseType, responseType());
    p.insert(Key::clientIdentifier, d->clientCredentials.first);
    p.insert(Key::redirectUri, callback());
    p.insert(Key::scope, d->scope);
    p.insert(Key::state, state);
    if (d->modifyParametersFunction)
        d->modifyParametersFunction(Stage::RequestingAuthorization, &p);
    url.setQuery(d->createQuery(p));
    connect(d->replyHandler.data(), &QAbstractOAuthReplyHandler::callbackReceived, this,
            &QOAuth2AuthorizationCodeFlow::authorizationCallbackReceived, Qt::UniqueConnection);
    setStatus(QAbstractOAuth::Status::NotAuthenticated);
    qDebug("QOAuth2AuthorizationCodeFlow::buildAuthenticateUrl: %s", qPrintable(url.toString()));
    return url;
}

这是一个错误吗？

最佳答案

我只是通过子类化 MyOAuthHttpServerReplyHandler 并覆盖 callback() 的定义以返回我想要的 URI 来解决这个问题。
