我正在尝试使用 AWS Cognito 和 AWS Cognito Identity 创建管理面板。我的问题是我的 CognitoIdentityServiceProvider 变量没有任何与组相关的功能，但具有所有其他可用功能。

具体来说，我缺少adminAddUserToGroup , adminListGroupsForUser , adminRemoveUserFromGroup , createGroup , deleteGroup , getGroup , listGroups , listUsersInGroup , 和 updateGroup .

我正在这样设置我的变量。凭据设置正确。:

//Sign in, get creds, then do this.
admin = new AWSCognito.CognitoIdentityServiceProvider({
            credentials: AWSCognito.config.credentials
        });

当我 console.log(admin); 时，我得到了下面的对象，我扩展了 __proto__ 以显示对象可用的功能。

b.constructor.b.constructor
_clientId:4
_originalConfig:(...)
get _originalConfig:()
config:constructor
endpoint:constructor
isGlobalEndpoint:false
__proto__: b.constructor.b.constructor

    __proto__: constructor

我包括了 aws-cognito-sdk.min.js 的最新版本, aws-cognito-identity-sdk.min.js ，以及 aws-sdk 的默认构建。

我收到的错误是:

对于文字墙，我很抱歉，但我只是希望你们了解所有事实，以更好地帮助我理解为什么我会收到此错误。我是否遗漏了包含或其他内容？

谢谢。

最佳答案

函数 adminAddUserToGroup、adminListGroupsForUser、adminRemoveUserFromGroup、createGroup、deleteGroup、getGroup、listGroups、listUsersInGroup 和 updateGroup 是经过身份验证的操作，因此您需要 AWS 凭证才能访问它们，正如您实际注意到的那样。

它们通过主 AWS SDK 公开，如您所见，它们应该在最新版本的 aws-sdk 中。

https://github.com/aws/aws-sdk-js/blob/master/apis/cognito-idp-2016-04-18.min.json#L339

您需要做的就是导入主要的 AWS SDK，实例化相应的客户端，您应该可以访问它们。

var client = new AWS.CognitoIdentityServiceProvider({ apiVersion: '2016-04-19', region });
