推荐答案

出于安全原因，您无法从浏览器调用任何网络服务，因此您必须使用 JSONP 应用程序端代理，或者您必须在服务器端启用 CORS.如果您打算将它构建为应用程序，那么您不必这样做，您所要做的就是在测试时更改浏览器的安全设置.更多细节在这里:如何使用json代理在开发过程中访问远程服务

You cannot call any webservice from your browser because of security reasons so either you have to use JSONP proxy on app side or you have to enable CORS on your server side. If you are planning to build this as app then you don't have to do this, all you have to do is change security setting of your browser when you are testing.
