如何获取 AccessToken

Question

我在 React 中使用以下插件 (@axa-fr/react-oidc-context) 以启用 AzureAd 身份验证。现在我需要在身份验证完成后访问 ApolloClient 中的 access_token。我不确定如何在像 ApolloClient 这样的非反应组件中获取 access_token。

这就是我正在做的事情。

App.js

import React from "react";
import { HashRouter, Route, Switch } from "react-router-dom";
import { AuthenticationProvider, withOidcSecure } from "@axa-fr/react-oidc-context";
import { IDENTITY_CONFIG } from "./utils/configuration";
// components
import Layout from "./Layout";

export default function App() {
  return (
    <AuthenticationProvider configuration={IDENTITY_CONFIG}>
      <HashRouter>
        <Switch>
          <Route path="/" component={withOidcSecure(Layout)} />
        </Switch>
      </HashRouter>
    </AuthenticationProvider>
  );
}

Layout.js

import React from "react";
import { Route, Switch, withRouter } from "react-router-dom";
import { ApolloProvider } from "@apollo/react-hooks";
import client from "./apollo";

import Dashboard from "./pages/dashboard";

function Layout(props) {
  return (
    <>
      <ApolloProvider client={client}>
        <Switch>
          <Route exact path="/" component={Dashboard} />
        </Switch>
      </ApolloProvider>
    </>
  );
}

export default withRouter(Layout);

apollo.js

import { InMemoryCache } from "apollo-cache-inmemory";
import { ApolloClient } from "apollo-client";
import { ApolloLink, split } from "apollo-link";
import { setContext } from "apollo-link-context";
import { HttpLink } from "apollo-link-http";
import { WebSocketLink } from "apollo-link-ws";
import { getMainDefinition } from "apollo-utilities";

import { useReactOidc } from "@axa-fr/react-oidc-context";

const { oidcUser } = useReactOidc();

console.log(oidcUser.access_token)

const httpUri = process.env.REACT_APP_SERVER_URL
  ? process.env.REACT_APP_SERVER_URL
  : "https://48p1r2roz4.sse.codesandbox.io";
const wsUri = httpUri.replace(
  /^https?/,
  process.env.REACT_APP_ENV === "dev" ? "ws" : "wss"
);

const httpLink = new HttpLink({
  uri: httpUri
});

const wsLink = new WebSocketLink({
  uri: wsUri,
  options: {
    lazy: true,
    reconnect: true
    // connectionParams: () => {
    //   return { headers: { Authorization: getAuthHeader() } };
    // }
  }
});

const authLink = setContext((_, { headers }) => {
  //   const auth = getAuthHeader()

  return {
    headers: {
      ...headers
      //   Authorization: auth,
    }
  };
});

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

const link = ApolloLink.from([terminatingLink]);
const cache = new InMemoryCache();

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

export default client;

我试图在 apollo.js 文件中提取访问令牌，但它抛出错误，提示我无法访问非 React 组件中的 React Hooks。

Answer 1

以前从未使用过这个库，但看起来它正在使用 higher order component 将 props 传递给您要传递给 withOidcSecure 的包装组件。您应该能够访问通过 Layout 组件中的 props 提供的任何数据。尝试在其中使用 console.log(props) 并查看它 returns，我不确定到底传递了什么数据。

Answer 2

由于令牌信息在身份验证后存储在 session 存储中，我能够从 session 存储中提取 access_token 信息并分配为授权 Header 到我的 ApolloClient.

如果有更好的解决方案请告诉我。

更新：

我们可以使用 useReactOidc 获取 access_token 作为传递给 Apollo Client 的道具，而不是获取 session 存储的令牌。请查看更新后的代码。

Layout.js

import React from "react";
import { Route, Switch, withRouter } from "react-router-dom";
import { ApolloProvider } from "@apollo/react-hooks";
import { useReactOidc } from "@axa-fr/react-oidc-context";
import client from "./apollo";

import Dashboard from "./pages/dashboard";

function Layout(props) {
  const { oidcUser } = useReactOidc();

  return (
    <>
      <ApolloProvider client={client(oidcUser.access_token)}>
        <Switch>
          <Route exact path="/" component={Dashboard} />
        </Switch>
      </ApolloProvider>
    </>
  );
}

export default withRouter(Layout);

apollo.js

import { InMemoryCache } from "apollo-cache-inmemory";
import { ApolloClient } from "apollo-client";
import { ApolloLink, split } from "apollo-link";
import { setContext } from "apollo-link-context";
import { HttpLink } from "apollo-link-http";
import { WebSocketLink } from "apollo-link-ws";
import { getMainDefinition } from "apollo-utilities";

const httpUri = process.env.REACT_APP_SERVER_URL
  ? process.env.REACT_APP_SERVER_URL
  : "http://localhost:8080/v1/graphql";
const wsUri = httpUri.replace(
  /^https?/,
  process.env.REACT_APP_ENV === "dev" ? "ws" : "wss"
);

const httpLink = new HttpLink({
  uri: httpUri
});

const wsLink = token =>
  new WebSocketLink({
    uri: wsUri,
    options: {
      lazy: true,
      reconnect: true,
      connectionParams: () => {
        return { headers: { Authorization: `Bearer ${token}` } };
      }
    }
  });

const authLink = token =>
  setContext((_, { headers }) => {
    return {
      headers: {
        ...headers,
        Authorization: `Bearer ${token}`
      }
    };
  });

const terminatingLink = token =>
  split(
    ({ query }) => {
      const { kind, operation } = getMainDefinition(query);
      return kind === "OperationDefinition" && operation === "subscription";
    },
    wsLink(token),
    authLink(token).concat(httpLink)
  );

const link = token => ApolloLink.from([terminatingLink(token)]);
const cache = new InMemoryCache();

const client = token =>
  new ApolloClient({
    link: link(token),
    cache: cache
  });

export default client;
