ID regione
Il REGION_ID è un codice abbreviato che Google assegna
in base alla regione selezionata durante la creazione dell'app. Il codice non
corrisponde a un paese o a una provincia, anche se alcuni ID regione possono sembrare
simili ai codici di paesi e province di uso comune. Per le app create dopo
febbraio 2020, REGION_ID.r è incluso negli
URL App Engine. Per le app esistenti create prima di questa data, l'ID regione è facoltativo nell'URL.
Per utilizzare l'autenticazione Firebase con il tuo servizio web, aggiungi
Firebase al tuo progetto Google Cloud e configura le impostazioni di autenticazione.
Aggiungi Firebase al tuo progetto Google Cloud esistente utilizzando lo strumento
Aggiungi progetto nella Console Firebase.
Puoi anche scegliere di utilizzare un account Firebase con un nome diverso, non associato al tuo progetto Google Cloud esistente.
Attiva i provider di accesso per l'autenticazione nella
console Firebase. Per questo
servizio web, devi attivare i provider
di accesso Email/Password e Google:
Fai clic su Build (Crea) > Authentication (Autenticazione) > Sign-in method (Metodo di accesso).
Nella sezione Provider di accesso, seleziona Email/Password.
Attiva il pulsante Attiva per utilizzare l'autenticazione tramite email e password e fai clic su Salva.
Affinché Firebase esegua l'autenticazione correttamente, il tuo dominio deve essere autorizzato
per i reindirizzamenti OAuth. Per autorizzare il dominio:
Nella sezione Domini autorizzati della pagina Impostazioni, fai clic su Aggiungi dominio.
Inserisci il dominio della tua app su App Engine, escluso il prefisso
http://:
PROJECT_ID.
REGION_ID.r.appspot.com
dove PROJECT_ID è l'ID del tuo
progettoGoogle Cloud .
Aggiungi Firebase al tuo servizio web
Per aggiungere Firebase al tuo servizio web, copia lo snippet di codice personalizzato, i file JavaScript e CSS del tuo progetto Firebase nel tuo servizio web:
Nella pagina di panoramica del progetto, sotto il testo Inizia aggiungendo
Firebase alla tua app, seleziona Web. Se hai già aggiunto un'app al progetto, potresti non visualizzare questo testo. In questo caso, vai alla pagina Panoramica del progetto > Impostazioni progetto > Generale della tua app esistente, scorri verso il basso e seleziona Aggiungi app.
Una volta registrata l'app, verrà visualizzato uno snippet di codice personalizzato. Copia
i contenuti dello snippet. Per visualizzare di nuovo questo snippet di codice in un secondo momento, vai alla pagina Impostazioni progetto della tua app Firebase.
Aggiorna il file templates/index.html completando le seguenti operazioni:
Aggiungi lo snippet di codice personalizzato al tag <body>.
Per questo tutorial, puoi aggiungere il codice all'inizio del corpo, poiché l'unico contenuto in templates/index.html è un esempio di servizi Firebase. Nell'ambiente di produzione, ti consigliamo di aggiungere lo snippet di codice in fondo al corpo, ma prima di utilizzare qualsiasi servizio Firebase.
Il codice personalizzato sarà simile a questo snippet di esempio:
Ora che hai aggiunto Firebase al tuo progetto Google Cloud e al tuo servizio web, puoi aggiungere codice al tuo servizio web per consentirgli di autenticare gli utenti.

Download the sample application repository using\n [Git](https://git-scm.com/):\n\n git clone https://github.com/GoogleCloudPlatform/python-docs-samples\n\n Alternatively, you can [download the sample](https://github.com/GoogleCloudPlatform/python-docs-samples/archive/master.zip) as a zip\n file and then extract it.\n 2. Navigate to the directory that contains a copy of the files from the\n previous step:\n\n cd python-docs-samples/appengine/standard_python3/building-an-app/building-an-app-1\n\nAdd Firebase to your Google Cloud project\n-----------------------------------------\n\nTo use Firebase authentication with your web service, add\nFirebase to your Google Cloud project and configure your authentication\nsettings.\n\n1. Add Firebase to your existing Google Cloud project using the\n **Add project** tool in the [Firebase console](https://console.firebase.google.com/).\n\n You can also choose to use a Firebase account with a different name, not\n associated with your existing Google Cloud project.\n2. Enable the authentication sign-on providers in the\n [Firebase console](https://console.firebase.google.com/). For this\n web service, you will enable **Email/Password** and **Google** sign-in\n providers:\n\n 1. Click **Build** \\\u003e **Authentication** \\\u003e **Sign-in method**.\n\n 2. Under **Sign-in providers** , select **Email/Password**.\n\n 3. Toggle the **Enable** button to use email and password authentication,\n and click **Save**.\n\n | **Tip:** For more information about enabling other providers, see the \"Before you begin\" sections of the [Google](https://firebase.google.com/docs/auth/web/google-signin), [Facebook](https://firebase.google.com/docs/auth/web/facebook-login), [Twitter](https://firebase.google.com/docs/auth/web/twitter-login), and [GitHub](https://firebase.google.com/docs/auth/web/github-auth) guides on Firebase.\n3. For Firebase to authenticate properly, your domain needs to be authorized\n for OAuth redirects. To authorize your domain:\n\n 1. Select **Build** \\\u003e **Authentication** \\\u003e **Settings**.\n\n 2. Under **Authorized domains** on the **Settings** page, click **Add Domain**.\n\n 3. Enter the domain of your app on App Engine, excluding the\n `http://` prefix:\n\n \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e.\n \u003cvar translate=\"no\"\u003e\u003ca href=\"#appengine-urls\" style=\"border-bottom: 1px dotted #999\" class=\"devsite-dialog-button\" data-modal-dialog-id=\"regional_url\" track-type=\"progressiveHelp\" track-name=\"modalHelp\" track-metadata-goal=\"regionalURL\"\u003eREGION_ID\u003c/a\u003e\u003c/var\u003e`.r.appspot.com`\n where \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e is the ID of your\n Google Cloud project.\n\nAdd Firebase to your web service\n--------------------------------\n\nTo add Firebase to your web service, copy your Firebase project's custom code\nsnippet, JavaScript and CSS files into your web service:\n\n1. Go to the [Firebase console](https://console.firebase.google.com/) and select your project.\n\n2. From the project overview page, under the text **Get started by adding\n Firebase to your app** , select **web** . If you already have an app added to\n the project, you may not see this text; instead, navigate to the\n **Project Overview** \\\u003e **Project settings** \\\u003e **General**\n page of your existing app, scroll down, and select **Add app**.\n\n3. Once the app is registered, a customized code snippet will be displayed. Copy\n the contents of the snippet. To see this code snippet again later, navigate\n to the **Project settings** page for your Firebase app.\n\n4. Update your `templates/index.html` file by completing the following:\n\n 1. Add the following lines to the `\u003chead\u003e` tag:\n\n \u003cscript src=\"https://www.gstatic.com/firebasejs/ui/6.0.1/firebase-ui-auth.js\"\u003e\u003c/script\u003e\n \u003clink type=\"text/css\" rel=\"stylesheet\" href=\"https://www.gstatic.com/firebasejs/ui/6.0.1/firebase-ui-auth.css\" /\u003e\n\n 2. Add your customized code snippet to the `\u003cbody\u003e` tag.\n\n For this tutorial, you can add the code to the top of the body, since the\n only content in `templates/index.html` is an example of Firebase\n services. In your production environment, we recommend that you add the\n code snippet to the bottom of the body, but before you use any Firebase\n services.\n\n Your custom code will look similar to this mock snippet: \n\n \u003c!-- MOCK SNIPPET: DO NOT COPY --\u003e\n \u003c!-- The core Firebase JS SDK is always required and must be listed first --\u003e\n \u003cscript src=\"https://www.gstatic.com/firebasejs/7.14.5/firebase-app.js\"\u003e\u003c/script\u003e\n\n \u003c!-- TODO: Add SDKs for Firebase products that you want to use\n https://firebase.google.com/docs/web/setup#available-libraries --\u003e\n\n \u003cscript\u003e\n var config = {\n apiKey: \"\u003cAPI_KEY\u003e\",\n authDomain: \"\u003cPROJECT_ID\u003e.firebaseapp.com\",\n databaseURL: \"https://\u003cDATABASE_NAME\u003e.firebaseio.com\",\n projectId: \"\u003cPROJECT_ID\u003e\",\n storageBucket: \"\u003cBUCKET\u003e.appspot.com\",\n messagingSenderId: \"\u003cSENDER_ID\u003e\",\n };\n firebase.initializeApp(config);\n \u003c/script\u003e\n\n 3. Replace the TODO in the snippet above with the following script tag to\n enable the Authentication component of Firebase:\n\n \u003cbr /\u003e\n\n ```\n \u003cscript src=\"https://www.gstatic.com/firebasejs/7.8.0/firebase-auth.js\"\u003e\u003c/script\u003e\n \n ```\n\n \u003cbr /\u003e\n\n These script addresses are documented in the [Firebase UI for Web\n documentation](https://firebaseopensource.com/projects/firebase/firebaseui-web/).\n 4. Replace the rest of the body with the following code, which you will use\n later in this guide to display authenticated user data:\n\n \u003cdiv id=\"firebaseui-auth-container\"\u003e\u003c/div\u003e\n\n \u003cbutton id=\"sign-out\" hidden=true\u003eSign Out\u003c/button\u003e\n\n \u003cdiv id=\"login-info\" hidden=true\u003e\n \u003ch2\u003eLogin info:\u003c/h2\u003e\n {% if user_data %}\n \u003cdl\u003e\n \u003cdt\u003eName\u003c/dt\u003e\u003cdd\u003e{{ user_data['name'] }}\u003c/dd\u003e\n \u003cdt\u003eEmail\u003c/dt\u003e\u003cdd\u003e{{ user_data['email'] }}\u003c/dd\u003e\n \u003cdt\u003eLast 10 visits\u003c/dt\u003e\u003cdd\u003e\n \t{% for time in times %}\n \u003cp\u003e{{ time['timestamp'] }}\u003c/p\u003e\n {% endfor %} \u003c/dd\u003e\n \u003c/dl\u003e\n {% elif error_message %}\n \u003cp\u003eError: {{ error_message }}\u003c/p\u003e\n {% endif %}\n \u003c/div\u003e\n\nNext Steps\n----------\n\nNow that you've added Firebase to your Google Cloud project and your web\nservice, you're ready to add code to your web service to enable it to\nauthenticate users."]]
