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。

Answer 1

webpack 参考这个看有没有帮助 https://webpack.docschina.org/configuration/dev-server/#devserverproxy

Answer 2

header带上这个 withCredentials: true 试一下

如果你请求用的axios:

axios.defaults.withCredentials = true

Answer 3

自己回答一下，其实出现下面这个提示表示已经没有跨域问题了，只是后端没有返回http ok状态而已：
Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

我的post参数传的有问题，在后端拦截器中就报错了，没有返回http ok的状态。故而出现了这个错误。
