React 登陆鉴权路由设置

主文件：

        <HashRouter >
          <ErrorBoundry>
            <Suspense fallback={Loading()}>
              <Switch>

                <Route exact path="/login" component={Login}/>
                {/* 要经过登录验证的页面都要使用PrivateRoute包装 */}
                <PrivateRoute exact path="/" component={Home1}/>
                <PrivateRoute path="/user" component={User1}/>

                <PrivateRoute path="/detail/:id" component={Detail}/>
                <Route path="*" component={NotFound}/>
              </Switch> 
            </Suspense>
          </ErrorBoundry>
        </HashRouter>

PrivateRoute:

const PrivateRoute = (props) => {
    const { user: { isLogin , isAdmin} , component: Cmp , ...rest } = this.props;
    const pathname = this.props.location.pathname; // 从哪儿来
    const NCmp = HFhoc(Cmp);
    return isLogin ? // 如果是已经登录的状态 去其他界面 应该就是对应的界面

      <Route 
        {...rest}
        render = {props => {
          return <NCmp {...props}/>
        }}
      />
      :
      <Redirect to={{
        pathname:'/login',
        state: pathname
      }}/> 
}

Login:

const Login = () => {


  if (user.isLogin) {

      return <Redirect to={pathname} />
    }

return <div>Login</div>
}
