How do you do this?
Use Admin API from Frontend(Headless Commerce) to get products from Shopify
<template>
<div>{{ data }}</div>
</template>
<script>
import axios from 'axios';
export default {
name: 'ShopifyResult',
data () {
return {
data: null
}
},
mounted () {
const url = 'https://a-shopify-store.myshopify.com/admin/api/2021-10/checkouts.json';
axios({
method:'get',
url,
headers: {
"Content-Type": "application/json",
"X-Shopify-Access-Token": 'API_ADMIN_ACCESS_TOKEN_HERE',
},
}).then((result) => {
console.log(result.data)
}).catch(error => {
console.log(error)
});
}
}
</script>
This is what I get:
Access to XMLHttpRequest at
'https://a-shopify-store.myshopify.com/admin/api/2021-10/checkouts.json'
from origin 'http://localhost:8080' has been blocked by CORS policy:
Response to preflight request doesn't pass access control check: No
'Access-Control-Allow-Origin' header is present on the requested
resource. ShopifyResult.vue?4048:27 AxiosError
Why is CORS involved? I have a all the appropriate keys. How do you do this?
I also found

Think of it this way:
Storefront API is a public API and the token for it is meant to be
used on the client side.
Admin API is a private API and the token is not meant to be shared
publicly. If you share this token to everyone by making requests from
the browser, they can potentially access private information about
your store, financial information, CUSTOMER information etc.
This could lead to both inconvenience to your customers as they would
be subject to fraud as well as you could run into legal issues if
someone decides to sue you because of it.
Hence, Shopify throws a CORS error when detecting that you use a
browser to send a request to a private API. While the CORS error might
not be the most appropriate response here, it is valid for them to
deny your request.
Hope that clarifies the issue for others encountering this error.

I have an Azure search index called users that has CORS configured to * (for now) to allow all origins. When I make a GET request to it programmatically using fetch or axios, I get a CORS error:
Access to XMLHttpRequest at 'https://MY_SEARCH_SERVICE.search.windows.net/indexes/users/docs?api-version=2021-04-30-Preview&%24top=5&search=matt*&%24searchFields=name&%24select=id%2Cname%2Cemail&api-key=MY_API_KEY' from origin 'http://localhost:5173' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource
However, if I put the same GET URL into a browser, it returns the list of expected results with no errors.
Here's my code (to run, create a Svelte app and put this in App.svelte or use the Svelte REPL. You must also have an Azure Search service set up, and you'll need to replace the placeholder variables MY_SEARCH_SERVICE and MY_API_KEY with your own, along with an index on which you want to try this):
<script lang="ts">
import { onMount } from "svelte";
const service = "https://MY_SEARCH_SERVICE.search.windows.net";
const index = "users";
const endpoint = `${service}/indexes/${index}/docs`;
const params = new URLSearchParams({
"api-version": "2021-04-30-Preview",
"api-key": "MY_API_KEY",
"$top": "5",
"$searchFields": "name,email",
"$select": "id,name,email"
});
const headers = new Headers({
"accept": "application/json"
});
onMount(async () => {
console.log(`${endpoint}?${params}`);
const response = await fetch(`${endpoint}?${params}`, {
headers: headers
});
console.log(await response.json());
});
</script>
when I run the following code from the client side in javascript as the coinbase cloud documentation says https://docs.cloud.coinbase.com/exchange/reference/exchangerestapi_getcoinbaseaccounts
const options = {
method: 'GET',
headers: {
Accept: 'application/json',
'cb-access-key': 'Apikey',
'cb-access-passphrase': 'Mypassphrase',
'cb-access-sign': cb_access_sign,
'cb-access-timestamp': cb_access_timestamp
}
};
fetch('https://api.exchange.coinbase.com/coinbase-accounts', options)
.then(response => response.json())
.then(response => console.log(response))
.catch(err => console.error(err));
when I do it with axios the same thing happens
the following error appears in console: "Access to fetch at 'https://api.exchange.coinbase.com/coinbase-accounts' from origin 'http://localhost:3000' has been blocked by CORS policy: Request header field cb-access-passphrase is not allowed by Access-Control-Allow-Headers in preflight response."
what am I doing wrong?
You can't do this in the browser, you need to do it from the web server. You can either display the data when the page loads or use vue/react and write your own interaction with the webserver.
edit: doing this in the browser makes your keys visible...
Coinbase API has misconfigured CORS (or intentionally require you to make API calls from a server). Regardless, this makes it very hard to test in a dev environment. This can be solved using a proxy. This can be configured using cors-anywhere which changes the api call flow from:
Client (localhost:3000) <-> Coinbase API (api.exchange.coinbase.com)
to
Client (localhost:3000) <-> Proxy Server (www.your-proxy-server.com) <-> Coinbase API (api.exchange.coinbase.com)
In summary, coinbase will only see a request coming from your proxy server and does not care/know where the proxy server sends back the data. Cors-anywhere will also include the headers and data along with the request.
Do not use public cor-anywhere servers unless you are quickly testing something. It is best to set up your own.
Using Firebase
I used cors-server to set mine up using firebase functions. You want your Firebase functions to look like the following:
const {onRequest} = require("firebase-functions/v2/https");
const corsAnywhere = require('cors-anywhere');
const cors = require("cors")({origin:true})
const corsServer = corsAnywhere.createServer({
originWhitelist: [
'http://localhost:3000',
],
requireHeader: ['origin', 'x-requested-with'],
removeHeaders: ['cookie', 'cookie2'],
});
exports.proxy = onRequest((request, response) => {
cors(request,response,() =>{
corsServer.emit('request', request, response);
})
});
and an example of a request in your client code
return(
axios({
url: `https://proxy-your-function-id.a.run.app/https://api.exchange.coinbase.com/profiles`,
headers: await getHeaders(options),
method: 'GET',
data: options.body
}).then((response)=>{
return(response)
}).catch((err)=>{
return(err.response)
})
)
Edit: It should also be noted that Coinbase is getting rid of Coinbase Pro and its API end of 2022. Coinbase exchange and its API will still be available at https://api.exchange.coinbase.com however Pro users will be merged into Advanced Trading on their main platform which uses oAuth to link the API (or standard keys for personal projects).
I'm trying to work on a Nuxt SSR frontend that uses a Django backend with Session Authentication.
I would like to have some SSR pages as well as client rendered pages in my frontend, so i'm using Universal mode.
The problem is that i did not find a working approach to check if a user is authenticated before loading a page, so i can't restrict pages to anonymous users. In order to check if a user is authenticated, Django will check if the request's headers contain a cookie, and according to that return if the user is authenticated or not.
Here is what i tried:
1) Middleware
export default async function ({context, redirect}) {
axios.defaults.withCredentials = true;
return axios({
method: 'get',
url: 'http://127.0.0.1:8000/checkAuth',
withCredentials: true,
}).then(function (response) {
//Redirect if user is authenticated
}).catch(function (error) {
console.log(error)
});
}
Here i'm sending a request to my backend to check if the user is authenticated. The problem is that the middleware is executed from server side, which means there will never be any cookie in the request, even if the user is authenticated. This means that every time i refresh the page, according to the middleware the user is always anonymous, even when the user is authenticated.
2) Plugin
export default function (context, inject) {
if (process.client){
console.log('client')
return axios({
method: 'get',
url: 'http://127.0.0.1:8000/checkAuth',
withCredentials: true,
}).then(function (response) {
//IF AUTHENTICATED, REDIRECT
context.redirect('/')
}).catch(function (error) {
console.log(error)
});
} else {
console.log('server')
}
}
Here i'm trying the same but with a plugin, and i'm "forcing" the plugin to check if the user is authenticated on the backend only when the plugin executes from client side. This works, cookies are sent in the headers and Django receives the cookie, but the problem with this solution is that Nuxt doesn't allow redirecting to other pages from a plugin (https://github.com/nuxt/nuxt.js/issues/4491).
3) Using beforeMount() in Vue
I tried to do that using beforeMount() from my Vue pages, but the problem is that since it will execute AFTER idration, the page will be loaded and after 1/2 seconds the redirect happens, which is kind of ugly.
Is it possible that there isn't a way to do this? Any kind of advice is appreciated
EDIT: the problem is not that i don't know how to code this, the problem is that when Nuxt sends a request to my backend from the server side middleware, the request will not contain any cookie, and because of this my Django backend cannot check the session cookie, which means that the backend cannot check whether or not the user is authenticated. The same code works when the middleware is executed from client side (if i navigate directly to the page instead of refreshing), because the request will contain the cookies.
I'm trying to understand if this is normal or not, but this could be an issue with Nuxt.
I know this a year old question and it was probably about nuxt 2, now nuxt 3 is out and running and I found my self with the same problem and here is how I solved it, just in case someone stumble here just like I did.
With Nuxt 3 server side you can use useFetch with the options headers: useRequestHeaders(['cookie'])
const { data, error, pending, refresh } = await useFetch(api.auth,
{
credentials: "include",
headers: useRequestHeaders(['cookie'])
}
);
There are a few issues you need to be aware of:
_ The cache, if you perform the same request with the same parameters it will return the same cached response (it won't even call the end point API). Try to use the key option with different values or the returned refresh method and check the doc "Data fetching" for more info.
_ The cookies, any cookie generate server side won't be shared with the client side, this means if the API generate a new token or session cookie on server side the browser won't receive those cookies and may generate new ones, this may get you in some 400 - bad request if you use session with CSRF, check this issue for more info.
I do have a working middleware with this
export default ({ redirect, store }) => {
if (store?.$auth?.$state?.loggedIn) {
redirect('https://secure.url')
} else {
redirect('https://login.please')
}
})
I am building a web application with a go backend and a vue.js frontend.
I want to do a simple sign in form in which I send the sign in request from a method of my component with Axios (or fetch) and get in response a JSON object of the user and a session token in the cookie to be stored and reused in future requests to the server.
The code of my components method :
class LoginComponent extends Vue {
sendLogin (): void {
axios.post<User>('http://192.168.1.227:8080/signin', body)
.then(res => console.log('Axios Response :', res)
.catch(err => console.error('Axios Error :', err))
}
}
The part of the code of the go server :
go API
with the headers :
go headers
the front and backend are on different IP addresses in a local network and they communicate through HTTP.
The problem that I faced is that when receiving the response after the post request to login I don't have access to the cookie that has been set by the server. When I use Axios to analyze the response the cookie isn't in the headers whereas when I look at the network logs in the browser, the cookie is in the headers but it is not saved and it is not sent when I do another request.
Also, the only header that is visible with Axios is Content-Type : application/json; charset=UTF-8
I tried many things to be able to see this cookie but it doesn't work :
adding { withCredentials: true } to the axios request or axios.defaults.withCredentials = true to the axios instance only stops the request because of CORS.
changing all the Access-Control headers to "*" didn't change anything
using { auth: { username: 'foo', password: 'bar' } } in the axios options instead of the body
The only thing that worked and automatically saved the cookie was to send the request via the attributes of the form html tag, like so :
<form method="POST" action="http://192.168.1.227/signin">
...
</form>
But this way I am redirected to the JSON response object and not to one of my routes from vue-router and I can't access the User object in my app.
Is there any way that my problem can be solved?
Ok so the comment of Зелёный was the answer.
I needed the go server to set Access-Control-Allow-Origin: http://192.168.1.218:8080 (the address of the frontend) and then configure axios with { withCredentials: true } to be able to automatically store the cookie. Although I still don't see it when I do a console.log on the axios response, it is successfully stored and reused for each call to the server.
I am using the below code to get the customer details from shopify. I have redirected my domain to the other domain from the shopify admin.
function setEmailWithLoggedInUser(callback) {
$.ajax({
url: 'https://new-website-shopify.myshopify.com/admin/customers/'+__st.cid+'.json',
crossDomain: true,
beforeSend: function(xhr) {
xhr.setRequestHeader("Authorization", "Basic XXXXXXXXXXXX")
}, success: function(data){
console.log(data);
if(callback)
callback();
}
})
I have done a lot of work around but unable to find the solution.
I am getting this error:
Failed to load resource: the server responded with a status of 404
(Not Found)
XMLHttpRequest cannot load
https://new-website-shopify.myshopify.com/admin/customers/7094124372.json.
Response to preflight request doesn't pass access control check:
No 'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'https://www.beirutshopping.com' is therefore not
allowed access. The response had HTTP status code 404.
I will save you some headaches with this answer. You cannot call /admin from the front-end of a store, as that exposes your access token to the public. Instead, if you want to access the API from the front-end, use the App Proxy pattern, allowing you to securely make Ajax calls to accomplish your goals.
As it is, you are almost certain to fail, and any success you hack into existence will quickly expose your shop to horrors. Like being replaced with sad pandas, or otherwise being reckd.
var cors = require('cors');

res.setHeader("Content-Type", "application/liquid");
res.setHeader("Access-Control-Allow-Origin", "*");
