How to add multiple isRevoked for different api's in expressjwt? - api

How to add multiple isRevoked for different api's in expressjwt? For example, if I have 3 roles (like:- admin,coordinator and volunteer) then how to specify function separately?
const expressJwt = require('express-jwt')
function authJwt(){
const secret = process.env.secret
const api = process.env.API_URL;
return expressJwt({
secret,
algorithms: ['HS256'],
isRevoked: isRevoked
}).unless({
path: [
`${api}/users/login`,
`${api}/users/register`
]
})
}
async function isRevoked(req, payload, done) {
if(!payload.isAdmin){
done(null,true)
}
done();
}
module.exports = authJwt

Next-auth how to decrypt session-token

I am controlling user authentification in my next app with next-auth library
I am using the credentials provider. First I call the login endpoint which returns the user informations then I take the access token and put it inside the token given by next-auth callback.
this is my code in [...nextauth].js
const authOptions = {
session: {
strategy: "jwt",
},
providers: [
CredentialsProvider({
type: "credentials",
credentials: {},
async authorize(credentials, req) {
const { email, password } = credentials;
const result = await axios.post(
`http://127.0.0.1:5000/user/login`,
{
email,
password,
},
{
headers: { "Content-Type": "application/json" },
withCredentials: true,
}
);
return {
accessToken: result.data.accessToken,
};
},
}),
],
callbacks: {
async jwt({ user, token }) {
if (user?.accessToken) {
token.value = user.accessToken;
}
console.log(token); //<-- output below
return token;
},
},
};
output :
{
value: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjYzOTZiMTlhYTczMmUzMzYwMjU2ZjBlMiIsImlhdCI6MTY3NTAyMzEwNSwiZXhwIjoxNjc1MTA5NTA1fQ.5kdPmeLCpwbJBjtzKMhe5QMNEx75ThiDKm75PN0vjoc',
iat: 1675023106,
exp: 1675109506,
jti: 'd9108700-1b5f-4bd3-8d31-0c36f38d9fcb'
}
Now in getServerSideProps I can get it from the request because it is sent in Cookie
export async function getServerSideProps(context) {
console.log(context.req.cookies["next-auth.session-token"]); // <-- output in Blockquote
return {
// does not matter
};
}
I get this :
eyJhbGciOiJkaXIiLCJlbmMiOiJBMjU2R0NNIn0..6ryJ60GPcDLq9aWG.4oWlJbecyWUnbZYJiv6z0eAuFmRFSfEn4fQSlh1FTjlPiiDGZASA4UwqXNEHRpRMG6HRPRDcsUUCHBBzaV8JwCEetgSYJcSrZ5CK_AhyvFKUlKY-TpHSNDnmCI8ZS4y2nV_Xl0NqvMU3vA-D8gXtT5UcOrJLlN5dMe7S9xZo8vhr-gpohcEhKOefUgDjTmMYmBf190OLl0TY599FkJwpoeSFozAwavwbOZGQOxYVbsj3KTibsfE37juyqnDaiV_t59bWroGjz2d5kHLxfkpQB0IKYRnAH8sXbG7dDZUVLT1UQUN_FrjYpkFrQgxC7MmWZtCccQs-FsBXY7EbiYmJKIddpOeN1Q.1kas8bGE_O7IkEDiilxiZw
Now I want to decrypt this token to get its property 'value' (which is the accessToken) and use it.
is it possible to decrypt it with javascript ? Thank you for your attention !
this funciton is inside next-auth/jwt module:
async function decode(params) {
const {
token,
secret
} = params;
if (!token) return null;
const encryptionSecret = await getDerivedEncryptionKey(secret);
const {
payload
} = await (0, _jose.jwtDecrypt)(token, encryptionSecret, {
clockTolerance: 15
});
return payload;
}
since this is not exported you have to export all module
import jwt from "next-auth/jwt"
// since you reached the token inside getServerSidePrps passed here
jwt.decode(token,passYourSecret)
May jwt.decode(token,secret) works as montioned in #Yilmaz answer but there is a built-in helper method getToken() for doing that
For convenience, this helper function is also able to read and decode tokens passed from the Authorization: 'Bearer token' HTTP header.
import { getToken } from "next-auth/jwt";
const secret = 'MY_SECRET';
export default async function handler(req, res) {
const token = await getToken({ req, secret })
console.log("JSON Web Token", token)
res.end()
}
If using NEXTAUTH_SECRET env variable, we detect it, and you won't actually need to secret
export default async function handler(req, res) {
const token = await getToken({ req })
console.log("JSON Web Token", token)
res.end()
}

Problem with Authentication using Apollo and React-native

I have this authentication issue
The registration works perfectly and the servers take the registration data: User password email and number. After this step, I have OTP verification
I got the pin code and run the verification mutation.
On the verification, I got the error :
You are not authenticated
And the all process stops because I am not verified
Here is the code for the react-native part
const VERIFY = gql
mutation($token: String!, $kind: TokenKind!) {
verify(token: $token, kind: $kind)
}
const VerificationScreen: React.FC < any > = (props) => {
const token = (props as any).route.params.token;
const [loading, setLoading] = React.useState < boolean > (false)
const [pin, setPin] = useState < string > ('')
const [veryfy] = useMutation(VERIFY)
const verifyPin = () => {
if (!pin) {
alert('Please TYPE Valid PIN')
return;
}
//veryfy
setLoading(true);
veryfy({
variables: {
token: pin,
kind: 'PHONE'
}
}).then(({
data
}) => {
setLoading(false)
console.log(data);
if (data) {
props.navigation.navigate('Intro', {
token: token
});
}
}).catch((e) => {
setLoading(false)
console.log(e);
})
}
The below code is an example showing how you can use the Apollo middle-ware [1] and context [2] to add headers(auth) at runtime or testing.
First we create a middle-ware block, then an inner context block.
In the context block we can use the line below to add external parameters, this is to configure the request
const { isAuth, Authorization } = headers;
A boolean(Auth) can be set to allow a token to be embedded in a Authorization header, or an existing Authorization header can be passed in directly, this can be usefull for testing for example.
const getClient = () => {
// create link middleware see [1]
const authMiddleware = new ApolloLink((operation, forward) => {
// code block below assumes there exists an auth token in globals
// add headers with the client context [2]
operation.setContext(({ headers = {} }) => {
// auth header using global token as a bearer token
const authHeaders = {
Authorization: global.access_token
? `Bearer ${global.access_token}`
: "",
};
// here an Authorization header can be passed in thru the context,
// which can be useful, eg for testing
const { isAuth, Authorization } = headers;
// if we have an Auth.. header we can just add that and return
if (Authorization) {
return {
headers: { ...publicHeaders, ...{ Authorization } },
};
}
const header = isAuth
? { ...publicHeaders, ...authHeaders }
: publicHeaders;
return {
headers: header,
};
});
return forward(operation);
}); // end create middleware
// create the graphql endpoint [1]
const httpLink = new HttpLink({ uri: '/graphql' });
// create client with the middleware and return the client
// code block below assumes there exists a globalCache
return new ApolloClient({
cache: globalCache,
link: concat(authMiddleware, httpLink),
});
}
use
// add/configure the appropriate headers in the context block
// for the client
client
.mutate({
mutation: <some mutation>,
variables: <some variables>,
context: {
headers: {
isAuth: false, // or true for authenticated operation
},
},
})
.then((result) => ....)
.catch((err) => {
console.log(....);
});
use in a hook
const [runMutation, { data }] =
useMutation(<gql>, {
context: {
headers: { isAuth: true },
variables: <some vars>,
onCompleted: (data) => callback(data),
onError: (error) => console.error("Error ", error),
},
});

Express-jwt is not returning any response

I'm trying to create a Login functionality using express-jwt, and using the middleware function in my app.js file. But whenever I'm trying to send a get request using the postman, it sending request for infinite of time and never returns back any error or success message.
I'm using dynamoDB as database.
here's my Login.js file
const AWS = require("aws-sdk");
const express = require("express");
const bcrypt = require("bcrypt");
const jwt = require("jsonwebtoken");
require("dotenv").config();
AWS.config.update({ region: "us-east-2" });
const docClient = new AWS.DynamoDB.DocumentClient();
const router = express.Router();
router.post("/login", (req, res) => {
user_type = "customer";
const email = req.body.email;
docClient.get(
{
TableName: "users",
Key: {
user_type,
email,
},
},
(err, data) => {
if (err) {
res.send("Invalid username or password");
} else {
if (data && bcrypt.compareSync(req.body.password, data.Item.password)) {
const token = jwt.sign(
{
email: data.Item.email,
},
process.env.SECRET,
{ expiresIn: "1d" }
);
res.status(200).send({ user: data.Item.email, token: token });
} else {
res.status(400).send("Password is wrong");
}
}
}
);
});
module.exports = router;
Here's my jwt.js file:
const expressJwt = require("express-jwt");
require("dotenv").config();
function authJwt() {
const secret = process.env.SECRET;
return expressJwt({
secret,
algorithms: ["HS256"],
});
}
module.exports = authJwt;
And I'm trying to use the expressJwt like this in my app.js file:
app.use(authJwt); //If I'm not using this, then the code works fine without API protection
Can Anyone tell me what's wrong with my code?
Any help from your side is appreciated.
Remove function from your jwt.js ,it should look like this
const expressJwt = require('express-jwt');
const secret = process.env.secret
const authJwt = expressJwt({
secret,
algorithms:['HS256']
})
module.exports = authJwt;

Multiple API providers with nuxt-axios and a plugin for default headers

I have a Nuxt app with many request to the same API, but also i need to make request to different providers apart of my main API and i don't know how to manage the default headers.
This is my working setup create a plugin to add the headers to all the request like this:
plugins/axios.js
export default function({ $axios, store, redirect }) {
$axios.onRequest(config => {
config.headers.common.Authorization = 'token 123';
config.headers.common["Custom-header"] = 'blablabla';
}
}
nuxt.config.js
module.exports = {
plugins: ["#/plugins/axios"],
axios: {
baseURL: process.env.API_URL,
}
}
store.js
async changeKeyVersionOnline({ commit }) {
const response = await this.$axios.get(
`users/1`
);
return response;
},
This works great for the main API but the problem is i need also to make request to other endpoints of third party service provider and of course the headers should be different.
How can i do that, i read about the proxy option of the nuxt-axios package but what i understand is this only changes the request base URL, i cant find how to set different headers to a specific request.
My final solution was based on create some actions in a central store so the axios requests are made trough this actions.
central.js (Where the axios related actions live)
import qs from "qs";
export const state = () => ({
accessToken: "",
clientId: 0
});
export const getters = {
getHeadersWithAuth: state => {
const config = {
headers: {
Authorization: "Bearer " + state.accessToken
}
};
return config;
},
getHeadersWithAuthClient: state => {
const config = {
headers: {
Authorization: "Bearer " + state.accessToken,
Client: state.clientId
}
};
return config;
}
};
export const mutations = {};
export const actions = {
async getWithAuth({ getters }, { path, params }) {
const config = getters.getHeadersWithAuth;
config.params = params;
config.paramsSerializer = function(params) {
return qs.stringify(params, { encode: false });
};
const result = await this.$axios.get(path, config);
return result;
},
async getWithAuthClient({ getters }, { path, params }) {
const config = getters.getHeadersWithAuthClient;
config.params = params;
config.paramsSerializer = function(params) {
return qs.stringify(params, { encode: false });
};
const result = await this.$axios.get(path, config);
return result;
},
async putWithAuthClient({ getters }, { path, body, params }) {
const config = getters.getHeadersWithAuthClient;
config.params = params;
config.paramsSerializer = function(params) {
return qs.stringify(params, { encode: false });
};
const result = await this.$axios.put(path, body, config);
return result;
}
};
test.js Other store which use the custom axios requests
async updateProductDetailsAction({ commit, dispatch, state }, productData) {
const request = {
path: `endpoints/` + productData.id + `/details`,
body: {
length: 123,
name: 'The product name'
},
params: {}
};
const result = await dispatch("auth/putWithAuthClient", request, {
root: true
});
await commit("setProductDetails", productData.id);
return result;
}

How do I configure Amplify to to use multiple AppSync endpoints?

I need to support authenticated and unauthenticated AppSync requests in a React Native app. Since AppSync only allows one authorization type per API, I am setting up two APIs: one for authenticated users (Cognito User Pools), and one for guests (API Key).
I think to make this work I need to have two distinct AWSAppSyncClient configs in the same app.
// authenticated user
const appSyncAuthenticatedClient = new AWSAppSyncClient({
url: Config.APPSYNC_AUTHENTICATED_ENDPOINT,
region: Config.APPSYNC_REGION,
auth: {
type: 'AMAZON_COGNITO_USER_POOLS',
jwtToken: async () =>
(await Auth.currentSession()).getAccessToken().getJwtToken()
}
});
// guest
const appSyncUnauthenticatedClient = new AWSAppSyncClient({
url: Config.APPSYNC_UNAUTHENTICATED_ENDPOINT,
region: Config.APPSYNC_REGION,
auth: {
type: 'API_KEY',
apiKey: Config.APPSYNC_API_ID
}
});
and then determine which to use based on whether or not they are logged in
Auth.currentAuthenticatedUser()
.then(user => this.appSyncRunningClient = appSyncAuthenticatedClient)
.catch(err => this.appSyncRunningClient = appSyncUnauthenticatedClient);
const App = props => {
return (
<ApolloProvider client={this.appSyncRunningClient}>
<Rehydrated>
<RootStack/>
</Root>
</Rehydrated>
</ApolloProvider>
);
};
export default App;
This fails because currentAuthenticatedUser returns a promise, and I'm stuck at how to resolve a promise at this top level instantiation of the app. I'll also need to swap out this config during auth events.
In what way can I dynamically select and change the ApolloProvider config at startup and authentication events?
This is currently not possible. Until top-level await is officially supported you should create two Apollo clients one for the API and one for the Cognito.
for example: in your App.js
export default function App(props) {
const [client, setClient] = useState(null);
useEffect(() => {
checkAuth()
}, []);
function checkAuth() {
Auth.currentSession().then(session => {
const token = session.getIdToken();
const jwtToken = token.getJwtToken();
if (typeof jwtToken == "string") {
const authClientConfig = {
url: awsmobile.aws_appsync_graphqlEndpoint,
region: awsmobile.aws_appsync_region,
disableOffline: true,
auth: {
type: AUTH_TYPE.AMAZON_COGNITO_USER_POOLS,
jwtToken: jwtToken
}
}
const link = ApolloLink.from([createAuthLink(authClientConfig), createSubscriptionHandshakeLink(authClientConfig)]);
const authClient = new ApolloClient({ link, cache: new InMemoryCache({ addTypename: false }) });
setClient(authClient);
} else {
throw "error";
}
}).catch(e => {
console.log(e);
const config = {
url: awsmobile.aws_appsync_graphqlEndpoint,
region: awsmobile.aws_appsync_region,
disableOffline: true,
auth: {
type: AUTH_TYPE.API_KEY,
apiKey: awsmobile.aws_appsync_apiKey
}
}
const link = ApolloLink.from([createAuthLink(config), createSubscriptionHandshakeLink(config)]);
const authClient = new ApolloClient({ link, cache: new InMemoryCache({ addTypename: false }) });
setClient(authClient);
})
}
if (!client) {
return "Loading..."
}
return (
<ApolloProvider client={client}>
...
</ApolloProvider>
);
}`
Things may have moved on as AppSync now supports multiple authentication types per API; however providing an answer as to how to auth/unauth on same endpoint for prosperity. Doesn't answer the how-to multiple endpoints question which is what led me here, but that's no longer required in OPs scenario.
Note: This answer applies to typescript - I'm not overly familiar with react but I think it will work exactly the same...
Unauthenticated access uses AWS_IAM / i.e. CognitoIdentityPool
(configured to allow unauthenticated access)
Authenticated Access users AMAZON_COGNITO_USER_POOLS authentication.
To switch between unauthenticated and authenticated API.graphql() calls. You need to test the current authentication status and use that to override the authMode as in the arguments to the API.graphql() call.
As a prerequisite:
The types in graphql must be setup to allow access via both #aws_iam and #aws_cognito_user_pools (see sample below)
The AppSync API must be configured to allow both authentication types (The code below assumes the API is configured for AWS_IAM by default, but allowed CognitoUserPools as an additional authentication type). This can be configured in console, or via cloudFormation.
Sample code for API call
let authMode;
try {
authMode = (await Auth.currentUserPoolUser()) ? GRAPHQL_AUTH_MODE.AMAZON_COGNITO_USER_POOLS : undefined;
} catch (err) { }
const result = await API.graphql({
...graphqlOperation(statement, gqlAPIServiceArguments),
authMode
});
Example grqphql type
type Profile #aws_iam #aws_cognito_user_pools {
username: ID!
stuff: String!
}
