How to store the contents of an external Csv file into a variable in Javascript?

Question

JavaScript

I can't figure out what I'm doing right? I need to transfer the body of the Csv file to a variable

const url = "http://www.aaa.com/uploads/1.csv"; // 
fetch(url, {
    mode: "no-cors",
    headers: {
        'Content-Type': 'text/csv'
    }
})
    .then(response => {
        return response.ok ? response.text() : Promise.reject(response.status);
    })
    .then(text => {
        return console.log(text.toString())
    })
    .catch(error => console.log("Can’t access " + url + " response. Blocked by browser?" + error))

Mistake

Can’t access http://www.aaa.com/uploads/1.csv response. Blocked by browser? 0

Answer 1

Can't access www.aaa.com/uploads/1.csv response. Blocked by browser? 0

Code 0 indicates network problems. Check the availability of the resource to rule out network problems.
If the resource is available, then the problem is on the browser side, dig towards security and certificates (usually towards CORS or HTTPS certificates).
