Exploring the process of dynamically incorporating headers into requests within react-admin

Currently utilizing react-admin with a data provider of simpleRestProvider. I am in need of a solution to dynamically add headers to requests based on user interactions.

Is there a way to achieve this?

Appreciate any assistance. Thank you!

Absolutely, it is entirely feasible. One convenient spot to integrate into the react-admin's workflow is through the httpClient that is supplied to the dataProvider. You can find more details about this in the documentation here.

    import { fetchUtils, Admin, Resource } from 'react-admin';
    import simpleRestProvider from 'ra-data-simple-rest';

    const httpClient = (url, options = {}) => {
        if (!options.headers) {
            options.headers = new Headers({ Accept: 'application/json' });
        }
        const { token } = JSON.parse(localStorage.getItem('auth'));
        options.headers.set('Authorization', `Bearer ${token}`);
        return fetchUtils.fetchJson(url, options);
    };
    const dataProvider = simpleRestProvider('http://localhost:3000', httpClient);

Note: If you need to dynamically pass headers for each invocation of the dataProvider, you may need to adjust the implementation of the dataProvider. The current version of ra-data-simple-rest does not directly provide the options parameter to the httpClient. You could enhance this functionality by modifying the package accordingly. No need to start from scratch - just fork the repository and enhance as needed.
