在 React JS 应用程序中，我想创建一个谷歌日历事件。我完全不熟悉 google api，我正在尝试学习/弄清楚如何做到这一点。

以下是一个反应测试组件，它显示一个带有“google登录”按钮和“添加到日历”按钮的空白屏幕。

我为此示例创建了一个 TEST_EVENT 常量。

用户必须先登录，然后单击“添加到日历”按钮。我确实获得了访问令牌 - 下一步是创建事件。我的问题是，如果我有 access_token，如何使用 fetch API 创建日历事件？

import React, { useEffect, useState } from 'react'
import jwt_decode from "jwt-decode";

const CLIENT_ID = '25262567698-tsaoo718sc35n3k25os074b17jklc5rm.apps.googleusercontent.com';
const SCOPES = 'https://www.googleapis.com/auth/calendar';

const TEST_EVENT = {
    'summary': 'Example Event',
    'location': 'New York, NY',
    'description': 'a description for this',
    'start': {
        'dateTime': '2023-03-26T10:00:00-04:00',
        'timeZone': 'America/New_York',
    },
    'end': {
        'dateTime': '2023-03-26T11:00:00-04:00',
        'timeZone': 'America/New_York',
    },
};

const TestGIS = (props) => {


    const [user, setUser] = useState({});
    const [tokenClient, setTokenClient] = useState({});

    function handleCallbackResponse(response) {
        console.log('encoded JWT ID token:' + response.credential);
        var userObject = jwt_decode(response.credential);
        console.log(userObject)
        setUser(userObject);
        document.getElementById('signInDiv').hidden = true;
    }

    function handleSignOut(event) {
        setUser({});
        document.getElementById('signInDiv').hidden = false;
    }



    useEffect(() => {

        /* global google */
        const google = window.google;
        google.accounts.id.initialize({
            client_id: CLIENT_ID,
            callback: handleCallbackResponse
        })
        google.accounts.id.renderButton(
            document.getElementById('signInDiv'),
            { theme: 'outline', size: 'large' }
        );

        // google.accounts.id.prompt(); // this is added to popup the login dialog when page is first loaded - didn't work

        // Get Access Token
        // create something called a tokenClient
        setTokenClient(
            google.accounts.oauth2.initTokenClient({
                client_id: CLIENT_ID,
                scope: SCOPES,
                callback: (tokenResponse) => {
                    console.log('tokenResponse=', tokenResponse);
                    // we now have access to a live token to use for ANY google API
                    if (tokenResponse && tokenResponse.access_token) {
                        // create the calendar event here

                    }
                }
            })
        );



    }, []);


    function createCalendarEvent() {
        tokenClient.requestAccessToken();
    }




    
    //-----------------------------------------------------------------
    return (

        


            

            {Object.keys(user).length != 0 &&
                 handleSignOut(e)}>Sign Out
            }

            {user &&
                

                    
                    
{user.name}
                     createCalendarEvent()}>Create calendar event
                
            }

        


    )
