javascript - AWS 认知 : Generate token and after refresh it with amazon-cognito-identity-js SDK

Question

我正在使用 amazon-cognito-identity-js 实现 node.js 后端。

我想创建一个 login(username, password) 和 refreshToken(token) API。

这是我的代码:

import { AuthenticationDetails, CognitoUser, CognitoUserPool, CognitoRefreshToken } from "amazon-cognito-identity-js"


   
public loginWithAmazonCognitoIdentity (username: string, password: string){
        
        var authenticationData = {
        Username : username,
        Password : password,
    };
    var authenticationDetails = new AuthenticationDetails(authenticationData);
    var poolData = { UserPoolId : 'eu-north-1_xxxxxx',
        ClientId : '3al0l3mhcxxxxxqgnp789987'
    };
    var userPool = new CognitoUserPool(poolData);
    var userData = {
        Username : username,
        Pool : userPool
    };
    var cognitoUser = new CognitoUser(userData);
    const user = cognitoUser.authenticateUser(authenticationDetails, {
        onSuccess: function (result) {
            var accessToken = result.getAccessToken().getJwtToken();
            console.log("token: " + accessToken);
            var refresh = result.getRefreshToken().getToken();
            console.log("RefreshToken: " + refresh);
        },

        onFailure: function(err) {
            console.error(err);
        },

    });

}

此函数返回 accessToken 和 refreshToken 没有错误。

在此之后，我实现了这个功能:

public refreshToken(refreshToken)
    var poolData = { UserPoolId : 'eu-north-1_xxxxxx',
            ClientId : '3al0l3mhcxxxxxqgnp789987'
            };
            var userPool = new CognitoUserPool(poolData);
    
            var userData = {
                Username : 'lacucudi',
                Pool : userPool
            };
            var cognitoUser  = new  CognitoUser(userData);
            var token = new CognitoRefreshToken({ RefreshToken: refreshToken })
            cognitoUser.refreshSession(token, (err, session) => { if (err) {console.log(err)} else console.log('session: ' + JSON.stringify(session)) });
}

但传递先前检索到的 refreshToken 会返回:

NotAuthorizedException: Invalid Refresh Token.

谁能告诉我这两个 api 的正确后端实现是什么？

我是这样解决的:

    import Amplify, { Auth } from "aws-amplify";
    import {
        AdminCreateUserCommand,
        AdminSetUserPasswordCommand,
        AuthFlowType,
        CognitoIdentityProviderClient,
        CognitoIdentityProviderClientConfig,
        GetUserCommand,
        InitiateAuthCommand,
        MessageActionType,
        RevokeTokenCommand,
    } from "@aws-sdk/client-cognito-identity-provider";

    public async login(username: string, password: string): Promise<AuthTokens> {
            if (!username || !password) {
                throw new HttpException(400, "Please provide both username and password");
            }
    
            Amplify.configure({ Auth: config.auth });
    
            const user = await Auth.signIn(username, password);
    
            if (!user.signInUserSession) {
                throw new HttpException(500, `Could not authenticate user ${username}`);
            }
    
            const {
                signInUserSession: {
                    accessToken: { jwtToken: access_token },
                    idToken: { jwtToken: id_token },
                    refreshToken: { token: refresh_token },
                },
            } = user;
    
            return {
                id_token,
                access_token,
                refresh_token,
            };
        }


public async refresh(refresh_token: string): Promise<AuthTokens> {
        if (!refresh_token) {
            throw new HttpException(400, "Please provide a refresh token");
        }

        const refreshTokenAuth = new InitiateAuthCommand({
            ClientId: config.auth.userPoolWebClientId,
            AuthFlow: AuthFlowType.REFRESH_TOKEN_AUTH,
            AuthParameters: {
                REFRESH_TOKEN: refresh_token,
            },
        });
        const response = await this.client.send(refreshTokenAuth);

        const {
            AuthenticationResult: { AccessToken, IdToken },
        } = response;

        return {
            refresh_token,
            access_token: AccessToken,
            id_token: IdToken,
        };
    }


public async logout(refreshToken: string): Promise<boolean> {
        if (!refreshToken) {
            throw new HttpException(400, "Please provide a refresh token");
        }
        try {
            const command = new RevokeTokenCommand({
                ClientId: config.auth.userPoolWebClientId,
                Token: refreshToken,
            });
            const response = await this.client.send(command);
            const { httpStatusCode } = response.$metadata;
            return httpStatusCode == 200 ?? true;
        } catch (e) {
            logger.error(e);
            throw new HttpException(500, e);
        }
    }

我使用 aws-amplify 进行登录，使用 aws-sdk/client-cognito-identity-provider 进行其他操作。

NotAuthorizedException: Invalid Refresh Token

返回错误消息是因为在 Cognito 设置中启用了设备跟踪选项。

令人难以置信的是，AWS 提供的服务会给出错误的错误消息并且相关文档很少
