如何在GraphQL后端ReactQL中为每个阿波罗添加一个头

Question

我想向GraphQL后端的每个请求中添加一个授权头。我使用的是Remotbackend。

阿波罗文档中有一个如何添加标题的示例：https://www.apollographql.com/docs/react/recipes/authentication.html#Header

import { ApolloClient } from 'apollo-client';
import { createHttpLink } from 'apollo-link-http';
import { setContext } from 'apollo-link-context';
import { InMemoryCache } from 'apollo-cache-inmemory';

const httpLink = createHttpLink({
  uri: '/graphql',
});

const authLink = setContext((_, { headers }) => {
  // get the authentication token from local storage if it exists
  const token = localStorage.getItem('token');
  // return the headers to the context so httpLink can read them
  return {
    headers: {
      ...headers,
      authorization: token ? `Bearer ${token}` : null,
    }
  }
});

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

但是我该如何用ReactQL来完成这个任务呢？

Answer 1

在ReactQL的回购示例中

https://github.com/reactql/example-auth

提到了一种方法：

  config.setApolloNetworkOptions({
    credentials: 'include',
  });

  config.addApolloMiddleware((req, next) => {
    const token = 'the_token'
    req.options.headers = {
      ...req.options.headers,
      authorization: token
    };
    next();
  });

这会将标题添加到每个请求！
