【问题描述】：

我正在使用 typescript 构建一个 MERN 堆栈应用程序。我正在为用户身份验证使用带有 openid-client 策略 (https://github.com/panva/node-openid-client/blob/master/docs/README.md#strategy) 的护照。我收到以下类型错误：

TypeError: client must be an instance of openid-client Client

我尝试过使用 Issuer.discover 和 new Issuer()，并等待/异步，确保 node 和我所有的包都是最新的，但无济于事。

这是相关代码：

import { Issuer, Strategy, generators } from "openid-client";

const googleClient = Issuer.discover("https://accounts.google.com/.well-known/openid-configuration")
    .then((googleIssuer: { Client: any; }) => {
        return googleIssuer.Client;
    });

它应该返回一个 openid-client 客户端实例，但它返回一个待处理的承诺。

标签： reactjs typescript passport.js openid-connect

【解决方案1】：

您可以“等待”一个承诺，然后它的“then”语句的返回值将被赋予 googleClient 变量的值。

试试这个

import { Issuer, Strategy, generators } from "openid-client";

let googleClient;
(async function discoverClient() {
  googleClient = await Issuer.discover("https://accounts.google.com/.well-known/openid-configuration")
  .then((googleIssuer: { Client: any; }) => {
    return googleIssuer.Client;
  });
})();

关于 async/await https://javascript.info/async-await 的一些有用信息

【解决方案2】：

解决方案供他人参考。我必须把所有东西都放在承诺中。

Issuer.discover('https://accounts.google.com/.well-known/openid-configuration')
    .then((googleIssuer: { issuer: any; metadata: any; Client: any; }) => {
        // console.log('Discovered issuer %s %O', googleIssuer.issuer, googleIssuer.metadata);
        const client = new googleIssuer.Client({
            client_id: process.env.GOOGLE_ID,
            client_secret: process.env.GOOGLE_SECRET,
            redirect_uris: ['list of URIs here'],
            response_types: ['code token id_token'],
        });

        const params = {
            client_id: process.env.GOOGLE_ID,
            response_type: 'code token id_token',
            scope: 'openid profile email',
            nonce: generators.nonce(),
            redirect_uri: 'URI here',
            state: generators.state(),
            prompt: 'select_account',
            display: 'popup',
            login_hint: 'sub',
        };

        const verify = ( tokenSet: any, userInfo: any, done: (arg0: null, arg1: any) => void ) => {
            console.log('USERINFO: ', userInfo);
            console.log('TOKENSET: ', tokenSet);
            return done(null, tokenSet);
        };

        const options = {
            client,
            params,
        };
        Passport.use('openid-client', new Strategy( options, verify ));
    }).catch((err: any) => {
        if (err) {
            console.log(err);
        }
    });
