useParseQuery 和 back4app 出现 401 错误

如何解决useParseQuery 和 back4app 出现 401 错误

我尝试使用带有 Parse 服务器的 back4end 作为我的 React Native 应用程序的后端，但无法进行查询。

我在 App.js 中初始化 Parse :

import React,{ useState,useEffect } from 'react';
import { Platform } from 'react-native'
import * as eva from '@eva-design/eva';
import { ApplicationProvider,IconRegistry } from '@ui-kitten/components';
import { EvaIconsPack } from '@ui-kitten/eva-icons';
import { AppNavigator,AuthNavigator } from './navigation';
import keys from './config/back4app';
import { initializeParse } from '@parse/react-native';
import UserContext from './config/context';

initializeParse(keys.serverURL,keys.applicationId,keys.javascriptKey);

export default () => {

    const [user,setUser] = useState(null);
    const [isLoading,setIsLoading] = useState(true);

    useEffect(() => {
        async function getCurrentUser() {
            if (user === null) {
                const currentUser = await Parse.User.currentAsync();
                if (currentUser !== null) {
                    setUser(currentUser);
                }
            }
        }
        getCurrentUser();
        setIsLoading(false);
      },[user]);
  
    if (isLoading) {
        return null; // spinner
    }

    return(
        <UserContext.Provider value={user}>
            <IconRegistry icons={EvaIconsPack}/>
            <ApplicationProvider {...eva} theme={eva.light}>
                { user ? <AppNavigator/> : <AuthNavigator/> }
            </ApplicationProvider>
        </UserContext.Provider>
    );
};

并尝试在另一个屏幕（Feed.js）中发出请求：

import React,{ useContext } from 'react';
import { StyleSheet,ActivityIndicator } from 'react-native';
import { Button,List,Text } from '@ui-kitten/components';
import { Page } from '../components/page';
import { Post } from '../components/post';
import { useParseQuery } from '@parse/react-native';
import UserContext from '../config/context';

export const FeedScreen = ({ navigation }) => {

    const user = useContext(UserContext);

    const parseQuery = new Parse.Query('Post');

    const {
      isLive,// Indicates that Parse Live Query is connected
      isLoading,// Indicates that the initial load is being processed
      isSyncing,// Indicates that the library is getting the latest data from Parse Server
      results,// Stores the current results
      count,// Stores the current results count
      error,// Stores any error
      reload // Function that can be used to reload the data
    } = useParseQuery(parseQuery);

    if (isLoading) {
        return <ActivityIndicator/>;
    }

    return (
        <Page navigation={navigation} title="Neurchi">
            <Text>welcome {user.get('username')}</Text>
            {error && (
                <Text>{error}</Text>
            )}
            <List
                style={styles.container}
                contentContainerStyle={styles.contentContainer}
                data={results}
                renderItem={(info) => <Post item={info.item}/>}
            />
        </Page>
    );
};

const styles = StyleSheet.create({
    container: {
    },contentContainer: {
      paddingHorizontal: 8,paddingVertical: 4,},item: {
      marginVertical: 4,});

我收到此错误： WebSocket connection to 'wss://parseapi.back4app.com/' Failed: Unexpected response code: 401

我尝试在另一个屏幕中再次初始化 Parse，但没有进行任何更改。此外，当我在 App.js 中发出请求时，它会起作用！所以我猜是授权问题...

希望有人有想法，提前谢谢！
