React Post请求跨域问题

Question

1. 前后端分离，前端ReactJS，后端PHP(Laravel), 本地调试的时候想调用远端接口。
2. 前端配置：在pakcage.json中配置代理如下：

"proxy": "https://www.shufadict.com/api",

1. 后端配置：Laravel添加中间件，配置允许跨域，如下：

header('Access-Control-Allow-Origin: *');
        header("Access-Control-Allow-Credentials: false");
        header("Access-Control-Allow-Methods: PUT, POST, GET, DELETE, OPTIONS");
        header("Access-Control-Allow-Headers: Content-Type, Access-Token, nonce, timestamp, packagename, sign, uuid");
        header("Access-Control-Expose-Headers: *");

结果，所有get请求都ok，但是post请求都返回如下错误：

Access to XMLHttpRequest at 'https://www.shufadict.com/' (redirected from 'http://localhost:3000/common/feedback') from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

求指点，困扰好几天了。
