javascript - 在 React Native 上使用 AWS amplify 登录

Question

我无法让 AWS Amplify 对我的 AWS Cognito 设置进行身份验证。我使用下面的代码来设置。

import Amplify from 'aws-amplify-react-native';
import { Auth } from 'aws-amplify-react-native';

Amplify.configure({
    Auth: {
        IdentityPoolId: 'us-west-2:XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX',
        region: 'us-west-2',
        UserPoolId: 'us-west-2_XXXXXXXX',
        ClientId: 'XXXXXXXXXXXXXXX'

    }
});

和这个登录代码

Auth.signIn(this.state.username, this.state.password)
.then(user => console.log(user))
.catch(err => console.log(err)); //"No userPool" logged here

但是，我将错误 No userPool 记录为错误。

这里的例子:https://github.com/aws/aws-amplify/blob/master/media/authentication_guide.md有一些以小写字母开头的配置属性，但是当我遵循它时，我得到了红屏。

这只是错误的配置。指南中的示例是:

import Amplify from 'aws-amplify';

Amplify.configure({
    Auth: {
        identityPoolId: 'XX-XXXX-X:XXXXXXXX-XXXX-1234-abcd-1234567890ab', //REQUIRED - Amazon Cognito Identity Pool ID
        region: 'XX-XXXX-X', // REQUIRED - Amazon Cognito Region
        userPoolId: 'XX-XXXX-X_abcd1234', //OPTIONAL - Amazon Cognito User Pool ID
        userPoolWebClientId: 'XX-XXXX-X_abcd1234', //OPTIONAL - Amazon Cognito Web Client ID
    }
});
