Question

我使用的是react-native，开箱即用的aws-amplify-react-native用于sigin注册用户。用户能够成功进行身份验证，但以“无当前用户”登录形式出现以下错误

我提高了日志级别以在应用程序中进行调试。我可以看到用户成功进行了身份验证，并且取回了JWT令牌，但是在日志中看到以下内容：

[DEBUG] 22:47.149 AuthClass - Failed to get user from user pool
[ERROR] 22:47.154 AuthClass - Failed to get the signed in user No current user
[DEBUG] 22:47.161 AuthPiece - No current user

下面是我的代码段：

import { ConfirmSignIn, ConfirmSignUp, ForgotPassword, RequireNewPassword, SignIn, SignUp, VerifyContact, withAuthenticator } from 'aws-amplify-react-native';

const RootStack = createStackNavigator(
  {
    Login: LoginScreen,
    Main: MainScreen,
    Customer: CustomerScreen,
    Reports: ReportsScreen,
    Signup: SignupScreen
  },
  {
    initialRouteName: 'Main',
  }
);

const AppContainer = createAppContainer(RootStack);

export class App extends React.Component {
  render() {
    return (
      <AppContainer />
    );
  }
}

export default withAuthenticator(App);

运行我的应用程序时。我看到默认的Amplify登录表单，我用它输入用户名和密码，然后单击“登录”按钮，该按钮成功进行了身份验证，但是出现了“无当前用户错误”，如上所示。

Answer 1

我有类似的问题。我从configure方法中删除了cookie存储块，它起作用了。

Answer 2

您是否正在使用cookieStore？如果为true，您是否使用安全标志？如果是这样，请在开发环境中将其值更改为false。

Answer 3

该错误字面意思是 No current user - 您需要使用支持的身份提供商登录。

我的解决方案：

import { Amplify } from "@aws-amplify/core";
import { Auth } from "@aws-amplify/auth";
import { CookieStorage } from 'amazon-cognito-identity-js';
import amplifyConfig from "../lib/Amplify";

Amplify.configure(amplifyConfig);

const cookieStorage = new CookieStorage(amplifyConfig.Auth.cookieStorage);
// cookie that is set before Cognito redirect to prevent infinite loop if authorization fails due to other reason than "No current user"
const redirectedFromAuthorize = cookieStorage.getItem("redirected-from-authorize");

...

Auth.currentAuthenticatedUser()
  .then(user => {
    setUser(user); // your custom function to do something with user attributes
    // authorization was successfull, we can remove the redirect cookie
    cookieStorage.removeItem("redirected-from-authorize");
  })
  .catch(err => {
    console.error(err);

    // if the cookie is set, it means the authorization failed again and you should not redirect back to Cognito
    if (!redirectedFromAuthorize) {
      // set redirect cookie, so that we know next time the error is reocurring
      cookieStorage.setItem("redirected-from-authorize", 'true');
      // redirect to Cognito hosted UI
      return Auth.federatedSignIn();
    }
  });

Amplify中没有当前用户为认证用户
