angularjs框架，路由指定为xx.html，直接在浏览器中打开时，路由跳转时会报错，错误信息如下：
angular.js:11756XMLHttpRequest cannot load file:xxxxxxx. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.
解决方法
This error is happening because you are just opening html documents directly from the browser. To fix this you will need to serve your code from a webserver and access it on localhost. If you have Apache setup, use it to serve your files. Some IDE's have built in web servers, like JetBrains IDE's, Eclipse...
如果在使用Node.js，可以下载安装http-server，npm install -g http-server。运行：http-server 工程目录。
