Vue.js GET request to API gets blocked by CORS

I am trying to fetch data from an API in Vue.js and console.log the response but I get a CORS problem, most specifically: from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I read that I need to create a vue.config.js file, I did but nothing changed, I also tried just using the fetch api, maybe I am making http calls the wrong way in Vue, how can I get my data and resolve this error?

Here is my component:

<template>
  <div class="container">
  </div>
</template>

<script>
import axios from "axios";

export default {
  name: "HelloWorld",
  methods: {},
  mounted() {
    axios
      .get(
        "https://base-url"
      )
      .then(response => console.log(response));
  }
};
</script>

and my vue.config.js:

module.exports = {
    devServer: {
        proxy: 'base-url',
    }
}

In the recent versions of vuejs, for example if the remote api is at http://localhost:9002/tasks then use server config.

// vite.config.js
import { defineConfig } from 'vite'

export default defineConfig({
  server: {
    proxy: {
      '/tasks': 'http://localhost:9002'
    }
  }
})

I found out what I was doing wrong, after setting up the proxy I had to change my get request to 

mounted() {
    axios
      .get(
        "http://localhost:8080/https://base-url"
      )
      .then(response => console.log(response));

That fixed the issue.

Do you have the header configuration setup for cors in your vue.config? Should look something like this.

Your should have 'Access-Control-Allow-Origin: ' Header

so make sure that your [api base url] returns this header to make your browser allow your request to go through without being (as way of protection)

More information about Access-Control-Allow-Origin

An Example in PHP:

<?php
  header('Access-Control-Allow-Origin: *') // to allow all sites
  ... the rest of the code

I think you may need to set up a middleware in the endpoint you are calling such as following:

// ACCEPTING CROSS SITE REQUESTS
api.use(cors());
api.use((req, res, next)=>{
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
  next();
});

Please try to add this to your endpoint API you are calling from so that new calls can be authorized.
