reactjs - ApolloClient 类型错误 ApolloLink

Question

我正在尝试使用 TypeScript 创建 ApolloClient，但有一些我无法解决的类型错误。谁能指出我正确的方向该怎么做？
以下是用于创建客户端的示例代码(可与 JavaScript 一起使用):

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

import { setContext } from 'apollo-link-context';
import { createHttpLink } from 'apollo-link-http';
import { getMainDefinition } from '@apollo/client/utilities';
import { WebSocketLink } from '@apollo/link-ws';

const authLink = setContext((_, { headers }) => {
  const token = localStorage.getItem('consequat-token');
  return {
    headers: {
      ...headers,
      authorization: token ? `bearer ${token}` : null
    }
  };
});

const httpLink = createHttpLink({ uri: 'http://localhost:4000' });

const wsLink = new WebSocketLink({
  uri: 'ws://localhost:4000/graphql',
  options: { reconnect: true },
});

const splitLink = split(
  ({ query }) => {
    const definition = getMainDefinition(query);
    return (
      definition.kind === 'OperationDefinition' &&
      definition.operation === 'subscription'
    );
  },
  wsLink,
  authLink.concat(httpLink)
);

const client = new ApolloClient({
  cache: new InMemoryCache(),
  link: splitLink
});

问题是 authLink.concat(httpLink)线路在提示:

Argument of type 'ApolloLink' is not assignable to parameter of type 'ApolloLink | RequestHandler | undefined'.
Type 'ApolloLink' is missing the following properties from type 'ApolloLink': onError, setOnError ts(2345)

我无法从 Apollo 文档或 Google 中找到任何答案。

回复我自己的帖子:

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

import { setContext } from 'apollo-link-context';
import { createHttpLink } from 'apollo-link-http';
import { getMainDefinition } from '@apollo/client/utilities';
import { WebSocketLink } from '@apollo/link-ws';

需要改为:

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

import { setContext } from '@apollo/link-context';
import { getMainDefinition } from '@apollo/client/utilities';
import { WebSocketLink } from '@apollo/link-ws';

那些 @apollo/和 apollo-库不兼容。另外， createHttpLink替换为 HttpLink进口自 @apollo/client ，它的用法:

const httpLink = createHttpLink({ uri: 'http://localhost:4000' });

变成:

const httpLink = new HttpLink({ uri: 'http://localhost:4000' });
