反应本机集成密钥库

Question

我想创建react native应用程序集成keycloack并获取令牌来访问Nodejs服务器api，我使用的包是react-native-app-auth，github：https://github.com/FormidableLabs/react-native-app-auth

但仍然无法正常工作，当我单击按钮应用程序退出并出现错误

时

在这里编码

<!-- language: lang-js -->

    import { authorize } from 'react-native-app-auth';

    const config = {
      issuer: 'http://localhost:8080/auth/realms/testrealms',
      clientId: 'passport',
      redirectUrl: 'io.identityserver.demo:/callback',
      scopes: ['openid', 'profile']
    };

export default class App extends Component<Props> {
  constructor(props) {
    super(props);
    this.state = {
      hasLoggedInOnce: false,
      accessToken: '',
      accessTokenExpirationDate: '',
      refreshToken: ''
    }
  }

  authorize = async () => {
    try {
      const authState = await authorize(config);

      this.setState(
        {
          hasLoggedInOnce: true,
          accessToken: authState.accessToken,
          accessTokenExpirationDate: authState.accessTokenExpirationDate,
          refreshToken: authState.refreshToken
        },
        500
      );
    } catch (error) {
      Alert.alert('Failed to log in', error.message);
    }
  };

  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          React Native Authorize By Keycloak
        </Text>
        <Text style={styles.instructions}>
          {this.state.accessToken}
        </Text>
        <View>
          {
            !this.state.accessToken && (
              <Button onPress={() => {
                this.authorize()
              }} title='authorize' />
            )
          }
        </View>
      </View>
    );
  }
}
