问题 I want to pass the data to the modal when the button edit is clicked like the id, email, and password. Just started with react. I'm using API here.

Here's the code, the this.state contains the fields from my API Toggle Modal and the fetch API to be returned using react-table import React from 'react'; import namor from "namor"; import ReactTable from 'react-table';

问题 I made a server query via an app developed using react-native. I used fetch API and it turns out any query with authorization header not working. POST and GET method REQUESTS that don't expect Authorization headers at the server side works well. Some Queries at the server side are protected with authorization and when I make such queries including authorization header, I always get '401:unauthorized' error. But such queries works well with POSTMAN. Any suggestions here would be of great help.
