Nodejs / Express Redirect after POST - express

I'm trying to rebuild an app based from PHP to MEAN and I've tried integrating a 3rd party payment gateway where users can enter their credit card info.
I was able to create a post request using the 'request' module and received a response status code 200 from the third party. Now that the request is fulfilled is there a way to redirect the user to the third party's site (similar to a POST request done with html forms and PHP)?
Here's the code block of the post request
function(req, res) {
request({
url: 'https://urlopaymentgateway',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
},
form:data,
followAllRedirects:true
},function(error,response,body){
if(error) {
console.log("FAIL");
console.log(error);
} else {
console.log(response.statusCode);
/* How to do redirection here? */
}
});
}
After further reading, the followAllRedirects work only if the status code is between 300 and 400.

I'm fairly new to node, but this works for me.
router.post('/some_path/', function(req, res) {
res.status(200).send('<html><body></body><script type="text/javascript">window.location.href="/some_new_path";</script></html>');
});

You can make redirects via res.redirect(), http://expressjs.com/api.html#res.redirect
Also, you may want to get redirected url from your POST request, here is it
function(error,response,body){
if(error) {
console.log("FAIL");
console.log(error);
} else {
console.log(response.statusCode);
var url = response.request.href
res.redirect(url)
}

Unexpected behaviour of payment_intent api with GET and POST method

I am using the payment_intent API to generate payment intent for payment sheet initialization.
As per the document, payment_intent is the POST method. Showing different errors in android and iOS.
https://stripe.com/docs/api/payment_intents/create
Note:- It's working in postman not working on mobile.
Case 1 Android
It is not working with the POST method. It worked with the GET method this is weird.
Case 2 iOS
It is not working with the GET and POST methods both.
With POST received the following error
_response": "{
\"error\": {
\"code\": \"parameter_missing\",
\"doc_url\": \"https://stripe.com/docs/error-codes/parameter-missing\",
\"message\": \"Missing required param: amount.\",
\"param\": \"amount\",
\"type\": \"invalid_request_error\"
}
}
With GET method received the following error
"_response":"resource exceeds maximum size"
End Point URL:-
let data = JSON.stringify({
customer: customerId,
currency: 'inr',
amount: 1000,
'automatic_payment_methods[enabled]': 'true',
});
let config = {
method: 'GET',
url: 'https://api.stripe.com/v1/payment_intents',
headers: {
Authorization:
'Bearer sk_test_DmXI7Jw1PnJAWYps3iCpvKkttIGX00pPfGLTjj',
'Content-Type': 'application/x-www-form-urlencoded',
},
data: data,
};
axios(config)
.then(function (response) {
console.info(JSON.stringify(response));
})
.catch(function (error) {
console.error('-----', error.response);
});
Following this document

Added snack URL to reproduce the issue.

Error Log
To clarify a few things:
1/ You shared your (test mode) secret key in your code snippet, please delete that and roll your API keys (https://stripe.com/docs/keys#keeping-your-keys-safe).
2/ Your iOS/Android apps should not be making requests to Stripe's APIs directly with your secret API key, as that means you are bundling your secret key with your apps which means anyone running your app has access to your secret key.
Instead, you need to make requests from your iOS app to your server and your server should use Stripe's server-side libraries to make requests to Stripe's APIs. Your iOS/Android apps can only make requests with your publishable key.
3/ The PaymentIntent endpoint supports both POST and GET. You can create a PaymentIntent by POSTing to the /v1/payment_intents endpoint, you retrieve a single PaymentIntent with a GET to the /v1/payment_intents/:id endpoint and you list PaymentIntents with a GET to the /v1/payment_intents endpoint.
4/ The error in your POST request shows "Missing required param: amount." so you need to debug your code to make sure the amount parameter is getting through. You can use Stripe's Dashboard Logs page https://dashboard.stripe.com/test/logs to debug what parameters your code is sending to Stripe's API.
Finally, I found a solution. The issue occurred because I am send parameters without encoding.
I found a solution from this link

Problems to get a refresh token using vue, nuxt and keycloak

I'm doing a project with vue, nuxt and keycloak as server for token, axios as http client and #nuxtjs/auth-next module for keycloak access.
I'm using a public client so I don't have a secret key which is the most recommended.
The part of getting the token and talking to the backend is working.
But as it is a public client it has no refresh token.
Searching the internet, a recommendation would be to post from time to time to the keycloak /token endpoint, passing the current token, to fetch a new token.
To perform this post, it doesn't work to pass json, having to pass application/x-www-form-urlencoded.
But it generates an error saying that the parameter was not passed.
On the internet they recommended passing it as url string, but then it generates an error on the keycloak server, as a parameter that is too long, because of the current token that is passed.
Below is the code used to try to fetch a new token.
This code is being called on a test-only button.
If anyone can help, I appreciate it.
const token = this.$auth.strategy.token.get()
const header = {
"Content-Type": "application/x-www-form-urlencoded"
}
const body = {
grant_type: "authorization_code",
client_id: "projeto-ui",
code: token
}
this.$axios ( {
url: process.env.tokenUrl,
method: 'post',
data: body,
headers: header
} )
.then( (res) => {
console.log(res);
})
.catch((error) => {
console.log(error);
} );
Good afternoon people.
Below is the solution to the problem:
On the keycloak server:
it was necessary to put false the part of the implicit flow.
it was necessary to add web-origins: http://localhost:3000, to allow CORS origins.
In nuxt.config.js it was necessary to modify the configuration, as below:
auth: {
strategies: {
keycloak: {
scheme: 'oauth2',
...
responseType: 'code',
grantType: 'authorization_code',
codeChallengeMethod: 'S256'
}
}
}

401 Unauthorized error in Express API post request

I am trying to develop the logic for a POST route handler in Express. I put the following together:
const headers = {
"Authorization":"TS Token asdfghjk-asdf-4567-fghjkl; tid=onfido-token";
"content-type": "application/json"
};
const params = {
"policy_request_id": "onfido_applicantandtoken"
};
app.get("/get_stuff", (req, res) => {
axios
.post("https://third/party/api", {
headers,
params
})
.then(function (response) {
res.json(response.data);
})
.catch(function (error) {
res.json("Error occured!");
});
}
});
I keep getting a 401 Unauthorized for the above. On Postman it works, but with the logic above I get a 401 Unauthorized, specifically in the logs I would get Header 'Authorization' not found or Could not parse authorization header. So I am unclear as to what could be going on with the header.
A lot of posts talk about req.headers, but my req.headers does not have the Authorization token and content-type in there, it has some other token that the API I am trying to connect to I assume needs to reach out to another API.
I have refactored it to look like this:
app.get("/get_stuff", (req, res) => {
axios
.post("https://third/party/api", params, headers)
.then(function (response) {
res.json(response.data);
})
.catch(function (error) {
res.json("Error occured!");
});
}
});
And I am still getting the same exact error.
To be clear the params is not something that gets passed into the URL on Postman, but rather the body of the postman request.
I was able to get it to successfully connect by declaring a global axios default like so:
axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;
as documented here:
https://www.npmjs.com/package/axios#user-content-config-defaults

How to properly use passport-github for REST API authentication?

I am building a vue.js client which needs to be authenticated through github oauth using an express server. It's easy to do this using server side rendering but REST API has been troublesome for me.
I have set the homepage url as "http://localhost:3000" where the server runs and I want the authorization callback url to be "http://localhost:8080" (which hosts the client). I am redirecting to "http://localhost:3000/auth/github/redirect" instead, and in its callback redirecting to "http://localhost:8080". The problem I am facing is that I am unable to send user data to the vuejs client through res.redirect. I am not sure if I am doing it the right way.
router.get("/github", passport.authenticate("github"));
router.get(
"/github/redirect",
passport.authenticate("github", { failureRedirect: "/login" }),
(req, res) => {
// res.send(req.user);
res.redirect("http://localhost:8080/"); // req.user should be sent with this
}
);
I have implemented the following approach as a work around :-
A route that returns the user details in a get request :
router.get("/check", (req, res) => {
if (req.user === undefined) {
res.json({});
} else {
res.json({
user: req.user
});
}
});
The client app hits this api right after redirection along with some necessary headers :
checkIfLoggedIn() {
const url = `${API_ROOT}auth/check/`;
return axios(url, {
headers: { "Content-Type": "application/json" },
withCredentials: true
});
}
To enable credentials, we have to pass the following options while configuring cors :
var corsOption = {
origin: true,
credentials: true
};
app.use(cors(corsOption));

How to redirect PUT request to POST request in express router route handler?

I am handling PUT /api/checkout route with express router:
this.router.put('/:id/checkout', (req, response, next) => { /*...*/ });
Now as I am handling different types of payments with different third party services one of which expects POST request I am looking for a way handle the PUT request by executing the POST request to third party service endpoint. How do I do that ?
What i did at this point is execute POST request directly with request.post.
The challenge at this point is how to handle the resource moved response.
request.post({
url : 'https://paymentgateway.com/charge',
form : {
product_id : product_id,
amount : amount
}
}, (err, httpResponse, body) => {
The response I get here is httpResponse.statucCode === 302 and body === <html><head><title>Object moved</title></head><body>. Not sure how to handle this. HTML form with same request parameters automatically redirects the client to redirect URL.
Returning the httpResponse to the client requesting the checkout action does the job. Client handles redirection automatically.
}, (err, httpResponse, body) => {
if (err) {
logger.error(err);
return response.status(err.code || 500).send(err);
}
return response.status(httpResponse.statusCode).send(httpResponse);
});
