我是React的新用户,在使用GraphQL创建一个简单的auth流程时出现问题,遵循React Router示例。

我希望/成为我的登录屏幕,只有在用户退出时才会显示。如果没有,应用程序应重定向到/dashboard(否则应该无法访问)。这就是我所拥有的,它在认证后生成无限循环:

class App extends Component {
    constructor(props) {
        super(props);

        this.state = {
            authenticated: false
        }
    }

    renderButtons () {
        if (this.state.authenticated) {
            return (
                <a>Logout</a>
            )
        }
        return null;
    }

    componentWillReceiveProps({ data }) {
        if (this.props.data.loading && !data.loading) {
            if (data.loggedInUser.id && !this.state.authenticated) {
                this.setState({authenticated: true});
            } else if (this.state.authenticated) {
                this.setState({authenticated: false});
            }
        }
    }

    render () {
        return (
            <div className="container">
                <nav>
                    {this.renderButtons()}
                </nav>
                <GatingRoute path="/" component={LoginPage} isAuthenticated={this.state.authenticated} newPath="/dashboard" />
                <PrivateRoute path="/dashboard" component={Dashboard} isAuthenticated={this.state.authenticated} />
            </div>
        );
    }
};

const PrivateRoute = ({ component: Component, isAuthenticated, ...rest}) => (
    <Route
      {...rest}
      render={props => (
        isAuthenticated
        ? (
           <Component {...props} />
        )
        : (<Redirect to={{ pathname: '/', state: { from: props.location } }} />)
      )}
    />
    );

const GatingRoute = ({ component: Component, isAuthenticated, newPath, ...rest}) => (
    <Route
      {...rest}
      render={props => (
        isAuthenticated
        ? (
            (<Redirect to={{ pathname: newPath, state: { from: props.location } }} />)
        )
        : 
        <Component {...props} />
      )}
    />
    );

export default graphql(query, { options: {fetchPolicy: 'network-only'}})(withRouter(App));

而不是像现在这样工作......

在您拥有路线的父组件中,执行以下操作

<BrowserRouter>
    <Route path=“/“ exact         render={ ( props ) =>
 props.user.loggedIn ? <Dashboard /> : <LoginForm />
}/>
</BrowserRouter>

这假定呈现路由器的组件知道用户状态。
