Origin is not allowed by Access-Control-Allow-Origin

See original GitHub issue

Hi, I’m using public API method in JavaScript on my local PC. But request failed because of Single-Origin-Policy.

The code is something like this.

<html>
<head>
  <meta chartset="utf-8">
  <script type="text/javascript" src="https://unpkg.com/ccxt"></script>
</head>
<body>
  <h1>jQuery Request</h1>
  <script>
    var bitflyer = new ccxt.bitflyer();
    bitflyer.fetchTicker('BTC/JPY').then(function(data) {console.log(data);});
  </script>
</body>
</html>

I received following error.

Origin null is not allowed by Access-Control-Allow-Origin.

How can I fix this?

@aiueogawa I can also suggest trying a public proxy:

bitflyer.proxy = 'https://cors-anywhere.herokuapp.com/'
# or
bitflyer.proxy = 'https://crossorigin.me/'

bitflyer.fetch_ticker('BTC/JPY')

If it works for you with any of these two proxies, then you still can set up a proper local proxy, just need to read more about their setup (depending on which one you choose).
