动态更新 Apollo 客户端使用的端点

Question

有没有办法动态更改使用getTenantEndpoint检索到的客户端使用的 URI？

const httpLink = new HttpLink({
  uri: `${getTenantEndpoint()}/graphql`,
  fetch
});

const authMiddleware = new ApolloLink(
  (operation: Operation, forward: NextLink) => {
    operation.setContext((_: any) => {
      return {
        headers: {
          ...operation.getContext().headers,
          Authorization: token && `Bearer ${token}`
        }
      };
    });

    return forward(operation);
  }
);


let apolloClient: ApolloClient<NormalizedCacheObject> | null = null;
const create = (initialState = {}): ApolloClient<NormalizedCacheObject> => {
  const httpLinkConfig: HttpLink.Options = {
    uri: `${getTenantEndpoint()}/graphql`,
    credentials: "same-origin"
  };
  if (!IS_SERVER) {
    httpLinkConfig.fetch = fetch;
  }
  return new ApolloClient({
    connectToDevTools: !IS_SERVER,
    ssrMode: IS_SERVER,
    link: from([
      authMiddleware,
      // @ts-ignore
      httpLink
    ]),
    cache: new InMemoryCache().restore(initialState)
  });
};

...

目前，我的（粗略）方法是在 localeStorage 中设置一个新的 URI（通过 getTenantEndpoint() 返回）并重新加载页面，但不需要完全重新加载页面的解决方案将是理想的。

有没有办法用authMiddleware覆盖 URI？
