即使规则设置为true，也可以用Firebase响应CORS问题

问题描述

我有99％的把握可以为自己的Firebase实时数据库正确设置规则。
React-Redux用于两个调用firebase
的react应用程序，但是问题很令人费解，
1）我创建了一个新的react应用程序并尝试执行axios POST / GET到firebase，但CORS错误不断发生

I am 99% sure that i set the rules correctly for my firebase realtime database.React-Redux is used for by both react app that call the firebaseHowever the problem is quite puzzling,1) I created a new react app and try to do an axios POST/GET to the firebase but CORS error keep happening

2）我使用了旧的react应用并调用了与（1）没有CORS错误相同的API，并且POST请求通过了。

2) I used my old react app and call the same API as (1) no CORS error and the POST request went through.

3）我测试了API是否使用邮递员，POST和GET请求都通过了

3) I test that the API works using postman, both POST and GET request went through

4）我还验证了Firebase在域下的权限设置中是否允许localhost

4) I also verified that localhost was allowed in the permission setting under domain for firebase

任何人都知道哪里出了问题吗？

Anyone got any idea what is wrong?

错误：

employee.js:42 Error: Network Error
    at createError (createError.js:17)
    at XMLHttpRequest.handleError (xhr.js:80)
