I would like to set up a Blazor client-side app with authentication through AWS Cognito.
When I run the app I'm not redirected to a login page, instead the page says "Authorizing..." for a few seconds, while I get this error in the console:
The loading of “https://blazorapp.auth.eu-central-1.amazoncognito.com/login?…Q&code_challenge_method=S256&prompt=none&response_mode=query” in a frame is denied by “X-Frame-Options“ directive set to “DENY“.
This error page has no error code in its security info
info: Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[2]
Authorization failed.
Then, the default "Hello, world!" index page is shown (even though as I understand it, it should not be visible to an unauthenticated user based on App.razor definition?). If I click on "Log in", I get the same error in console, but then after a few seconds the Cognito-hosted login page opens, I am able to log in, I am redirected back to my app, and the app shows the authenticated user's info in top right corner, but the console is a little weird again:
info: Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[2]
Authorization failed.
info: Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[1]
Authorization was successful.
Question 1
How can I get rid of these errors and have my app redirect to Cognito login page without ~10s delay?
Question 2
Why is all content in my app visible at all times regardless of whether I'm authenticated or not? It's as if the NotAuthorized node under AuthorizeRouteView in App.razor had no effect at all, unless I am confusing something here
Code:
Program.cs
builder.Services.AddOidcAuthentication(options =>
{
options.ProviderOptions.Authority = "https://cognito-idp.{aws-region}.amazonaws.com/{cognito-userpoolid}";
options.ProviderOptions.ClientId = "{cognito-clientid}";
options.ProviderOptions.ResponseType = "code";
options.ProviderOptions.RedirectUri = "https://localhost:44306/authentication/login-callback";
options.ProviderOptions.PostLogoutRedirectUri = "https://localhost:44306/authentication/logout-callback";
});
App.razor (as created from template, no modifications)
<CascadingAuthenticationState>
<Router AppAssembly="#typeof(Program).Assembly">
<Found Context="routeData">
<AuthorizeRouteView RouteData="#routeData" DefaultLayout="#typeof(MainLayout)">
<NotAuthorized>
#if (!context.User.Identity.IsAuthenticated)
{
<RedirectToLogin />
}
else
{
<p>You are not authorized to access this resource.</p>
}
</NotAuthorized>
</AuthorizeRouteView>
</Found>
<NotFound>
<LayoutView Layout="#typeof(MainLayout)">
<p>Sorry, there's nothing at this address.</p>
</LayoutView>
</NotFound>
</Router>
</CascadingAuthenticationState>
I have only modified the call to AddOidcAuthentication in Program.cs myself, all other files were populated by Visual Studio when creating a Blazor WebAssembly App with Individual User Accounts.
I am struggling to get this to work and would greatly appreciate any help on this topic
EDIT:
Following #aguafrommars's answer I have published the website to Amazon S3 using static website hosting with Amazon CloudFront as CDN, however, the behavior of the published app is exactly the same as described local behavior
To expand on the questions:
Question 1 expanded:
When the page says "Authorizing..." I only get the described error in the console, the Cognito hosted UI is not rendered, only when I click on "Log in" I am either redirected (with major delay) to Cognito hosted UI, or authenticated without redirection (if I signed in before), perhaps this GIF will clear things up:
I might be wrong, but isn't the problem that the Cognito hosted UI is rejecting to be rendered in an iframe? Can my app redirect to the hosted UI in the first place, like it eventually does? Right now I have to wait while X-Frame-Options error is thrown, click on "Log in", wait while another X-Frame-Options error is thrown, and then finally I'm redirected and the flow succeeds (in the gif the UI doesn't show up because I authenticated before in the session)
Question 2 expanded:
The behavior I want to achieve is that if the user is not authenticated, they cannot see any part of the application, instead they are redirected to Cognito hosted UI and only after they are authenticated they can see anything. I tried to play around with Authorize attribute in MainLayout.razor, but the result is always a blank screen, I would like to provide some code and details but I believe the behavior is impacted by errors described in Question 1, which is why I would like to sort it out first
I'm answering this issue which was marked as duplicate here...
The reason for the delay is the timeout waiting for the silent login process (which has a 10s timeout I believe) as mentioned here and here
Root cause is that AWS Cognito is not compliant with the OIDC standards. Which results in the "'X-Frame-Options' to 'DENY'" error in the browser console.
Until the Blazor team allow us to turn off the silent signin from code, the solution was to disable silent login as follows:
Download the Blazor Interop files located in the asp.net repo here to a local folder.
Open the local folder using vs code and install typescript, webpack, yarn, etc if not already installed
npm install -g yarn
npm install -g typescript
npm install -g webpack
Then edit the AuthenticationService.ts file as follows (commenting out the silent signin functionality). Sorry for the long code print.

Then build the js with
yarn build:release
Once the js file is compiled, copy the AuthenticationService.js file into the/wwwroot directory of your Blazor WASM app.
Then in the index.html file, comment out the MS script and replace with your own:
<!-- <script src="_content/Microsoft.AspNetCore.Components.WebAssembly.Authentication/AuthenticationService.js"></script>-->
<script src="AuthenticationService.js"></script>
Run your app and Cognito will now be (relatively) instantaneous
I ended up switching from Cognito to Auth0 and upgrading from Api Gateway's RestApi to HttpApi, which includes built in JWT authorizer, and I am very happy with the change. Cognito just had too many problems in the end, but if someone is determined to get it to work check #aguafrommars's comments under the accepted answer.
Response 1:
While the authorizing message is displayed, the app check for a valid authentication and set up auto renew token iframe. If you look at the network log on your browser you'll see requests made by this time.
When the app run in release it's faster.
Response 2:
You need to add authorization on pages you want to protect by adding the Authorize attribute.
#page "/"
#attribute [Authorize]
Had the same problem and switched out to Azure B2C which again resolved the issue. Appears to be a problem with the auth library when linking to AWS Cognito as the auth provider.

I have a requirement to automatically send push notifications to my application when new data is inserted into firebase.
Is there any way to do so ?
Thanks !
You can use Firebase Functions as a middleware function for sending push notifications via FCM to the device If the database value is changed.
Adding an example from my FirebaseDBtoFCMFunction repo.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.sendPushNotification = functions.database
.ref('/users/{user_id}') // Put your path here with the params.
.onWrite(async (change, context) => {
try {
const { after } = change;
const { _data } = after;
const { deviceToken } = _data.receiver; // Always send the device token within the data entry.
if(!deviceToken) return;
const payload = {
notification: {
title: 'Notification',
body: `FCM notification triggered!`
},
data: context.params // Passing the path params along with the notification to the device. [optional]
};
return await admin.messaging().sendToDevice(deviceToken, payload);
} catch (ex) {
return console.error('Error:', ex.toString());
}
});
Inside your application add child_change (valueChanged) or child_add event for specific database location than when it changes, it will fired.
From doc.
FirebaseDatabase.DefaultInstance
.GetReference("Leaders").OrderByChild("score")
.ValueChanged += HandleValueChanged;
}
void HandleValueChanged(object sender, ValueChangedEventArgs args) {
if (args.DatabaseError != null) {
Debug.LogError(args.DatabaseError.Message);
return;
}
// Do something with the data in args.Snapshot
}

In my work, we tried integrate Safari Push unsuccessful. We have the files .p12 and the .cer
When executing in Safari, not work, no response. If change the name of callback, for example for console.log('hi')... print "hi" and in the console, I see the error
"TypeError: undefined in not an object (evaluating
'window.safari.pushNotification.requestPErmission('https://fabse.tv,
pushId, { user: '123456'}, console.log('hi'))')"
This is my code:
my pushId: 'web.fbase.tv'
setupPushWeb() {
const isSafari = /^((?!chrome|android).)*safari/i.test(navigator.userAgent);
var checkRemotePermission = function (permissionData) {
if (permissionData.permission === 'default') {
// This is a new web service URL and its validity is unknown.
window.safari.pushNotification.requestPermission(
'https://fbase.tv', // The web service URL.
'web.fbase.tv', // The Website Push ID.
{user_id: '4741619481'}, // Data used to help you identify the user.
console.log('hola') // The callback function.
);
}
else if (permissionData.permission === 'denied') {
// The user said no.
}
else if (permissionData.permission === 'granted') {
// The web service URL is a valid push provider, and the user said yes.
// permissionData.deviceToken is now available to use.
}
}
if(isSafari) {
if ('safari' in window && 'pushNotification' in window.safari) {
var permissionData = window.safari.pushNotification.permission('web.fbase.tv');
checkRemotePermission(permissionData);
}

I'm using express + passport + nextjs to set up an app that will perform authentication using OpenID Connect. The user data is stored on the request object using express-session which gives me req.user on every request as usual.
Now I want to pass the user information to the front-end so that I can use it for something, but there does not seem to be any consistent way to do this for all requests. I can use getServerSideProps for individual pages, but not for every page through either _document or _app. How can I set this up?
Here is my current _document.tsx
import Document, {
Head,
Main,
NextScript,
DocumentContext,
} from "next/document"
export default class Doc extends Document {
public static async getInitialProps(ctx: DocumentContext) {
const req: any = ctx.req
console.log("req/user", `${!!req}/${!!(req && req.user)}`)
const initialProps = await Document.getInitialProps(ctx)
return {
...initialProps,
user: req?.user || "no user",
}
}
public render() {
return (
<html>
<Head />
<body>
<Main />
<NextScript />
</body>
</html>
)
}
}
It appears to return a request object only during the very first request, not any subsequent refreshes of the page.
I've created a small repo that reproduces the issue here: https://github.com/rudfoss/next-server-custom-req
It seems ridiculous that there is no way to do this for all pages in an easy manner.
Edit: For reference this is my server.js. It is the only other relevant file in the repo
const express = require("express")
const next = require("next")
const dev = process.env.NODE_ENV !== "production"
const start = async () => {
console.log("booting...")
const server = express()
const app = next({ dev, dir: __dirname })
const handle = app.getRequestHandler()
await app.prepare()
server.use((req, res, next) => {
req.user = {
authenticated: false,
name: "John Doe",
}
next()
})
server.get("*", handle)
server.listen(3000, (err) => {
if (err) {
console.error(err)
process.exit(1)
}
console.log("ready")
})
}
start().catch((error) => {
console.error(error)
process.exit(1)
})
It is recommended to do this via function components, as seen in the Next.js custom App docs:
// /pages/_app.tsx
import App, { AppProps, AppContext } from 'next/app'
export default function MyApp({ Component, pageProps }: AppProps) {
return <Component {...pageProps} />
}
MyApp.getInitialProps = async (appContext: AppContext) => {
// calls page's `getInitialProps` and fills `appProps.pageProps`
const appProps = await App.getInitialProps(appContext)
const req = appContext.ctx.req
return {
pageProps: {
...appProps.pageProps,
user: req?.user,
},
}
}
As in your answer, this will run on every request though so automatic static optimization will not be active.
Try a demo of changing pageProps in MyApp.getInitialProps (without usage of req.user) on the following CodeSandbox:
https://codesandbox.io/s/competent-thompson-l9r1u?file=/pages/_app.js
Turns out I can override getInitialProps on _app to make this work:
class MyApp extends App {
public static async getInitialProps({
ctx
}: AppContext): Promise<AppInitialProps> {
const req: any = ctx.req
return {
pageProps: {
user: req?.user
}
}
}
public render() {
//...
}
}
This will run on every request though so static optimization will not work, but in my case I need the information so I'm willing to accept the trade-off.
Edit: This answer also works, but it uses the "old" class-based component syntax which is no longer recommended. See answer from Karl for a more modern version using functional-component syntax.
I also had the similar problem where I had to fetch loggedIn user details from my Auth api. I solved it by wrapping my whole app inside a context provider, then using a set function for the initialState, which will remember if it was called before and fetch user details only once. Then in my each page, wherever I require these user details, I used the context to see if details are available and call the set function if details are not available. This way I think I achieved:
Only one request to fetch user details
Because it happens from the client side, TTFB is better
I can still take advantage of getStaticProps and getServerSideProps where it is required.
I am trying to use a completion handler in react-native is that possible?
pls some samples will help.
Thanks.
So i am calling this method in an instance class from a parent class, but want the method to return a value when done.
Right now its returns before the value is created but would rather like for the value to be passed once created.
getfcmToken() {
//generate token here
firebase.messaging().getToken().then(token => {
if (token) {
console.log("LOG: ", token);
_userID = token
alert(_userID)
} else {
// user doesn't have a device token yet
}
})
return this._userID;
}
I think you can just send a function as a parameter to getfcmToken. For example:
in helper/ instance class
getfcmToken(callback) {
firebase.messaging().getToken().then(token => {
if (token) {
this._userID = token;
callback({success: true, token: token};
} else {
// user doesn't have a device token yet
callback({success: false, message: 'User doesn't have device token'});
}
});
}
and then in parent class:
getUserToken() {
firebaseHelper.getfcmToken((result)=>{
if (success === true) {
//do something with token
}
});
}
I am trying to implement vue-authenticate, but I'm having an issue with the following example code taken from their documentation:
new Vue({
methods: {
login: function () {
this.$auth.login({ email, password }).then(function () {
// Execute application logic after successful login
})
},
register: function () {
this.$auth.register({ name, email, password }).then(function () {
// Execute application logic after successful registration
})
}
}
})
Where is the $auth property coming from? I can't see it defined anywhere. I've looked through the documentation, and the example code in the repo, but neither provide any help.
As you know vue-authenticate is a Vue-plugin.
And when you use this plugin using the line.
Vue.use(VueAuthenticate, ...data)
And this is where it gets defined in this file
Object.defineProperties(Vue.prototype, {
$auth: {
get() {
if (!vueAuthInstance) {
// Request handler library not found, throw error
if (!this.$http) {
throw new Error('Request handler instance not found')
}
vueAuthInstance = new VueAuthenticate(this.$http, options)
}
return vueAuthInstance
}
}
})
Also you may want to go through this documentation on Adding Instance Properties.
