Question

我在React钩子中使用了多个上下文和约简器。

这是我的App.js文件

import React from "react";
import { BrowserRouter as Router, Route, Switch } from "react-router-dom";

import Map from "./components/Map";
import Header from "./components/Header";
import Signup from "./components/Auth/Signup";
import Login from "./components/Auth/Login";
import UserList from "./components/User/UserList";

import "mapbox-gl/dist/mapbox-gl.css";

import { ApolloProvider } from "react-apollo";
import { ApolloClient } from "apollo-client";
import { WebSocketLink } from "apollo-link-ws";
import { InMemoryCache } from "apollo-cache-inmemory";
import { default as keysConfig } from "./keys.config";
import AuthProvider from "./providers/authProvider";
import withRoot from "./providers/withRoot";
import PageContent from "./pages/pageContent";
import ProtectedRoute from "./routePermissions/ProtectedRoute";
import AdminRoute from "./routePermissions/AdminRoute";
import PinProvider from "./providers/pinProvider";
import UserProvider from "./providers/userProvider";

const wsLink = new WebSocketLink({
  uri: `${keysConfig.WssBaseUrl}/graphql`,
  options: {
    reconnect: true
  }
});

const client = new ApolloClient({
  link: wsLink,
  cache: new InMemoryCache()
});

const App = () => {
  return (
    <Router>
      <ApolloProvider client={client}>
        <AuthProvider>
          <PageContent>
            <Header />
            <Switch>
              <PinProvider>
                <ProtectedRoute exact path="/" component={Map} />
              </PinProvider>
              <Route exact path="/login" component={Login} />
              <Route exact path="/signup" component={Signup} />
              <UserProvider>
                <AdminRoute exact path="/userlist" component={UserList} />
              </UserProvider>
            </Switch>
          </PageContent>
        </AuthProvider>
      </ApolloProvider>
    </Router>
  );
};

export default withRoot(App);

我正在使用多个上下文和简化器。它使我使用多个提供程序。但是我想使用提供者来指定路由。

当我像代码片段一样使用Route时，ProtectedRoute不起作用。

我希望有人能帮助我解决这个问题。您可以为我提供一个更好的方法，该方法如何更有效地将多个上下文和化简器组合到react挂钩中。

<Switch>适用于一级孩子。不管是<Route>还是<Provider>。因此，您需要调整组件内部的代码移动提供程序，或者仅利用render()的{{1}}变体：

Route

应该工作正常
