在初始化后更新ApolloClient标头

import { ApolloClient, InMemoryCache } from '@apollo/client';

const client = new ApolloClient({
  uri: 'https://example.com/graphql',
  cache: new InMemoryCache(),
  headers: {
    Authorization: 'Bearer <token>',
    CustomHeader: 'CustomValue',
  },
});

import { ApolloClient, InMemoryCache, createHttpLink } from '@apollo/client';
import { setContext } from '@apollo/client/link/context';

const httpLink = createHttpLink({
  uri: 'https://example.com/graphql',
});

const authLink = setContext((_, { headers }) => {
  // 更新标头
  const updatedHeaders = {
    ...headers,
    Authorization: 'Bearer <new_token>',
    CustomHeader: 'NewValue',
  };

  return {
    headers: updatedHeaders,
  };
});

const client = new ApolloClient({
  link: authLink.concat(httpLink),
  cache: new InMemoryCache(),
});
