如何使用Serverless将Cognito身份验证设置为仅包含电子邮件和密码？

Question

我使用Serverless生成Cognito用户池，但是当前，用户名和电话号码是必填字段，我的应用程序不需要该字段。我将Cognito与React应用一起使用，该应用通过

实现身份验证

curl https://www.xxxcustomdomainxxx.com/test --cookie "__session=testing"

无服务器看起来像这样：

import { withAuthenticator } from 'aws-amplify-react';

...

export default withAuthenticator(App);

我现在在这里搜索某些设置选项，但没有找到禁用电话和用户名的内容：

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-cognito-userpool.html

是否可以仅使用另一个无服务器配置来解决此问题，或者我是否也需要更改react实现？

可以像这样设置用于登录的字段，但是如果没有适当的配置，如果您只是“隐藏”登录表单中的字段，它会要求缺少用户名
