Expo 升级后 React Native Auth 会话停止工作

Question

我使用的是 Expo SDK 48，我的应用程序使用基于 Web 浏览器的身份验证方案与 Google 和 Facebook 身份验证运行良好。

工作代码：

type AuthResponse = AuthSession.AuthSessionResult & {
    params: {
        access_token?: string;
        error?: string;
    };
    type: string;
}
...

const AuthProvider = ({ children }: any) => {

/* Google */
    const signInWithGoogle = async (navigation: any) => {

        try {

            const SCOPE = encodeURI("email profile");
            const RESPONSE_TYPE = 'token';

            const authUrl = `https://accounts.google.com/o/oauth2/v2/auth?client_id=${GOOGLE_WEB_CLIENT_ID}&redirect_uri=${REDIRECT_URI}&response_type=${RESPONSE_TYPE}&scope=${SCOPE}`;

            const { type, params } = await AuthSession.startAsync({ authUrl }) as AuthResponse;
            console.log("type ==>> " + type);
            console.log("params ==>> " + JSON.stringify(params));


            if (type === 'success') {

                checkGoogleUserInfo(params.access_token, navigation);

            } else {
                return;
            }

        } catch (error) {

            console.log("Error retrieving token data from Google ==>> ", error);
        }

    }


}

Expo 升级到 SDK 50 以及

expo-auth-session

升级到

5.4.0

后，

AuthSession.startAsync()

停止工作。

我正在尝试使用 docs 中的新方法并遵循 this example 但在尝试从下面的代码中的 url 获取时遇到以下错误：

Possible unhandled promise rejection: SyntaxError: JSON Parse error: Unexpected character: <

无效代码：

const endpoint = "https://accounts.google.com/o/oauth2/v2/auth";
    const clientId: any = GOOGLE_WEB_CLIENT_ID;
    const redirectUri: any = REDIRECT_URI;
    const [discovery, setDiscovery] = useState({});

    useEffect(() => {

        async function loadDiscovery() {

            // here is the issue causing promise rejection
            const getDiscovery = await fetchDiscoveryAsync(endpoint).then((discovery) => setDiscovery({ discovery })); 

           // nothing is displayed in console
            console.log("get getDiscovery >>>>>> " + JSON.stringify(getDiscovery)); 
        }

        loadDiscovery();
    }, []);



    const [request, response, promptAsync] = useAuthRequest({ clientId, scopes: ['email', 'profile'], redirectUri }, discovery);

    useEffect(() => {

        console.log(discovery);

        if (!discovery) {
            console.log("no discovery");
            return;
        }

        if (response?.type === "error") {
            console.log("response type error: " + (response.params.error || "something went wrong"))
            return
        }

        if (!discovery || (response?.type !== "success")) {
            console.log("no discovery and no response type");
            return;
        }


        const code = response.params.code;
        if (!code) {
            console.log("no code");
            return;
        }


    }, [response, discovery]);

是否仍然可以使用基于网络浏览器的 Google 和 Facebook 身份验证？

编辑：

我最终使用

discovery

作为端点得到了

https://accounts.google.com

，结果是下面的 json。但我的

response

仍然是

null

。

如何使用这个发现文档？在用户输入其凭据后，我尝试从 Google 获取用户电子邮件，因为它在 SDK 更改之前正常工作。

Answer 1

当我终于找到Google的发现文档链接并使用Uber身份验证示例后，我可以打开网络浏览器身份验证来输入Google的凭据：

const discovery = {
    authorizationEndpoint: 'https://accounts.google.com/o/oauth2/v2/auth',
    tokenEndpoint: 'https://oauth2.googleapis.com/token',
    revocationEndpoint: 'https://oauth2.googleapis.com/revoke'
};


const AuthProvider = ({ children }: any) => {

     const [request, response, promptAsync] = useAuthRequest({
        clientId,
        scopes: ['email', 'profile'],
        redirectUri,
        responseType: 'code',
    },
        discovery
    );

    useEffect(() => {

        console.log("request >>>>>>>>>>>>>>>>>> " + JSON.stringify(request));
        console.log("response >>>>>>>>>>>>>>>>>> " + JSON.stringify(response));
        console.log("discovery >>>>>>>>>>>>>>>>>> " + JSON.stringify(discovery));

    }, [response]);

    ...

    /* Google */
    const signInWithGoogle = async (navigation: any) => {

    try {

        promptAsync();
   
    } catch (error) {

       console.log("Error retrieving token data from Google ==>> ", error);
    }

}

输入 Google 帐户登录后仍然遇到错误：

Something went wrong trying to finish signing in

但我认为这应该在另一个问题上讨论。
