android - ionic : No 'Access-Control-Allow-Origin' header is present on the requested resource

Question

这是我在研究后发现的允许跨源请求的 ionic.project

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

当我在我的 cmd 终端上运行 ionic serve 时，它​​会启动浏览器并在控制台上显示它

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.

有什么问题吗？

Answer 1

至于我，我使用这个插件来操作 Content-Security-Policy:

cordova-plugin-whitelist

这对我有帮助。
