Retrieving email with Google Sign In for Google Home

问题

so I've beentrying to retrieve the email associated with the current user using the google home.

Documentation is kind of hard to find on the subject and from what I could gather, I should be able to use the SignIn class from actions-on-google. So here is my setup.

DialogFlow -> Created two intent, one to start the sign in process, the other to follow up on the process. (The second one has the event 'actions_intent_SIGN_IN' to it.)

Actions on google config : Account Linking.

Selected - Yes, allow users to sign up for new accounts via voice
Selected - Linking Type : Google Sign In

And added the client id to my fulfillment layer by adding the clientId to my dialogflow config.

dialogflow({clientId})

So, when I run this in the emulator (I get the same exact thing on my google home device) I get an error as soon as my sign in goes to the followup intent (actions_intent_SIGN_IN), which is that my signin.status is Error. From there, I don't know what I can do to get more information on what this error is and how to fix it.

Any idea ? Thanks !

PS : It might not even be something that can be done ? Is there any other way to retrieve the email of the user ? I was able to retrieve it's name using Permission, but there's nothing more that SignIn for email as far as I know.

I can show you how I get my email address with the Google Account linking: You need to have your accessToken available then you could use what is shown in this answer. The accessToken is in conv.user.access.token when the SignIn is completed.

In node this looks like that:

let link = "https://www.googleapis.com/oauth2/v1/userinfo?access_token="+accessToken;
    return new Promise(resolve => {
        request(link,(error, response, body) => {
            if (!error && response.statusCode === 200) {
                let data = JSON.parse(body);
                let name = data.given_name ? data.given_name : '';
                conv.ask(new SimpleResponse({
                    speech: "Hello "+ name + "!",
                    text: "Hello "+ name + "!"
                }));
                resolve();
            } else {
                console.log("Error in request promise: "+error);
                resolve();
            }
        })
    })

Everything you need should be in the data object.

Hope it helps. About your error, I am not sure but try doing all step in the link above. I'm using the Sign-In required box with Dialogflow and not a new SignIn but it should work the same.
