Javascript 反应导航+;用于检查身份验证/受保护路由的高阶组件(HOC)
我遇到了一个问题,我正在使用高阶组件检查用户是否经过身份验证(checkAuth)。我的问题是,路由似乎受到保护,因为它不显示在屏幕上,但它确实加载了底部选项卡导航、标题,并且没有路由回登录屏幕 checkAuthTest只是我编写的一个函数,用于导航到对话屏幕:Javascript 反应导航+;用于检查身份验证/受保护路由的高阶组件(HOC),javascript,reactjs,react-native,react-navigation,higher-order-components,Javascript,Reactjs,React Native,React Navigation,Higher Order Components,我遇到了一个问题,我正在使用高阶组件检查用户是否经过身份验证(checkAuth)。我的问题是,路由似乎受到保护,因为它不显示在屏幕上,但它确实加载了底部选项卡导航、标题,并且没有路由回登录屏幕 checkAuthTest只是我编写的一个函数,用于导航到对话屏幕: // Check Auth Test (Testing) checkAuthTest = () => { try { console.log('Navigating to App Stack')

高阶组件:
// Check Auth Test (Testing)
checkAuthTest = () => {
try {
console.log('Navigating to App Stack')
console.log(`Current User: ${firebase.auth().currentUser}`);
// this.props.navigation.navigate('AppStack');

}
catch (error) {
console.log(error);

};
export default connect(mapStateToProps, mapDispatchToProps)(checkAuth(Conversations));
如果用户经过身份验证,则高阶组件将用户路由到该组件。如果用户未通过身份验证,则高阶组件将用户路由回登录屏幕

错误会告诉您出了什么问题。返回的是函数而不是元素:
constcheckauth=(OriginalComponent)=>props=>{
类CheckAuth扩展了React.Component{
// ...
}
//返回检查验证组件
返回CheckAuth;
}
现在,当您使用它时:
CheckAuth(对话)
结果:
const Component=props=>{
类CheckAuth扩展了React.Component{
// ...
}
//这是一个组件,但返回的是一个函数,而不是一个元素
返回CheckAuth;
}
您可能想要:
const CheckAuth=(原始组件)=>{
类CheckAuthComponent扩展了React.Component{
// ...
}
//返回检查验证组件
返回checkauth组件;
}
这里我删除了额外的
props=>
,因为您需要在这里返回组件(CheckAuth
),而不是返回组件的函数(props=>CheckAuth
)。我认为这与如何导出登录组件有关,你可以添加这个代码,这样我就可以查看它了吗?只是添加了它作为登录屏幕的代码。谢谢你的关注!因此,它现在可以工作并导航到登录屏幕,但React Navigation的标题和选项卡导航器仍然存在。你知道那是什么吗?按下按钮时,它应该导航到对话屏幕(应用程序堆栈),但HOC返回登录屏幕(验证堆栈)。
