create-react-app之proxy
【create-react-app之proxy】
create-react-app可以用于一键创建web_client环境，默认使用webpack-dev-server。但在开发过程中，往往需要client/server配合调试。当我们需要将请求发送到自有服务器而非webpack-dev-server时，怎么办呢?
To tell the development server to proxy any unknown requests to your API server in development, add a proxy field to your package.json, for example:
"proxy": "http://localhost:4000",
This way, when you fetch('/api/todos') in development, the development server will recognize that it’s not a static asset, and will proxy your request to http://localhost:4000/api/todos as a fallback. The development server will only attempt to send requests without a text/html accept header to the proxy.
