ionic：请求的资源上不存在“ Access-Control-Allow-Origin”标头

Question

This is my ionic.project to allow Cross Origin Request that I found after research

{
  "name": "AppName",
  "app_id": "",
  "proxies": [
    {
      "path": "/path",
      "proxyUrl": "http://www.url.com/path"
    }
  ]
}

When I run ionic serve on my cmd terminal, it launches the browser and I get this on the console

XMLHttpRequest cannot load http://www.url.com/Token. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.

What could be wrong?

Answer 1

As for me, I used this plugin to manipulate with Content-Security-Policy:

cordova-plugin-whitelist

This helped me.
