I will assume that you’re a front-end developer only and that you don’t have access to the backend of the application (regarding the tags of the question). You q2c coin are doing an XMLHttpRequest to a different domain than your page is on. So the browser is blocking it as it usually allows a request in the same origin for security reasons. You need to do something different when you want to do a cross-domain request. A tutorial about how to achieve that is Using CORS.
How can I solve ‘Redirect has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header’?
- In the end, solving the CORS issue can be done quite fast and easily.
- The reason being that those tools are not Web frontends, but rather some server-based tools.
- So the browser is blocking it as it usually allows a request in the same origin for security reasons.
- I found the solution in the article Build a simple CRUD application with Spring Boot and Vue.js.
You also need to understand that if you use Postman or any other tool to try your API call, you will not get the CORS issue. The reason being that those tools are not Web frontends, but rather some server-based tools. Its purpose is to mainly prevent the usage of a (malicious) HTTP call from a non-whitelisted frontend to your backend with some critical mutation. I am working on an application using Vue.js.According to my setting, I need to pass to a variable to my URL when a setting change.
Reason for the error
Regular web pages can use the XMLHttpRequest object to send and receive data from remote servers, but they’re limited by the same origin policy. An extension can talk to remote servers outside of its origin, as long as it first requests cross-origin permissions. A. If you are in control of the server, you could modify the response headers that the server sends to meet your use case.

But I realized after a lot of research that the problem was that I did not copy theright URL address from the iTunes API documentation. B. But looking closely, it seems like you are debugging this locally, in which case it would be easier to use a browser extension that does this for you. Altering headers requires the use of mod_headers. The approved answer to this question is not valid. In the end, solving the CORS issue can be done quite fast and easily. You only need to communicate with your team or find something on your side (if you have access to the backend/admin dashboard of some service).

You can also try a Chrome extension to add these headers automatically. The error in this case denotes that the Access-Control-Allow-Origin is missing from the server’s response. I found the solution in the article Build a simple CRUD application with Spring Boot and Vue.js. You have to customize security for your browser or allow permission through customizing security.
