如何使用 ajax 调用获取 Microsoft Graph API 访问令牌

当我在我的在线环境中测试此线程时，请求失败，因为它需要用户同意（官方指南）。

因此，我授予应用程序应用程序权限并由管理员使用管理员同意 url( https://login.microsoftonline.com/common/adminconsent?client_id=appid&state=12345 )批准它

现在，我可以通过以下端点访问日历视图：

https://graph.microsoft.com/v1.0/users/userid/calendarView/delta?startdatetime=2018-12-04T12:11:08Z&enddatetime=2019-01-04T12:11:08Z

我的测试代码：

<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            requestToken();
        });
        var token;
        function requestToken() {
            $.ajax({
                "async": true,
                "crossDomain": true,
                "url": "https://cors-anywhere.herokuapp.com/https://login.microsoftonline.com/tenant.onmicrosoft.com/oauth2/v2.0/token", // Pass your tenant name instead of sharepointtechie
                "method": "POST",
                "headers": {
                    "content-type": "application/x-www-form-urlencoded"
                },
                "data": {
                    "grant_type": "client_credentials",
                    "client_id ": "xxx", //Provide your app id
                    "client_secret": "xxx", //Provide your client secret genereated from your app
                    "scope ": "https://graph.microsoft.com/.default"
                },
                success: function (response) {
                    console.log(response);
                    token = response.access_token;
                    document.getElementById('content').innerHTML = token;

                    $.ajax({
                        url: 'https://graph.microsoft.com/v1.0/users/userid/calendarView/delta?startdatetime=2018-12-04T12:11:08Z&enddatetime=2019-01-04T12:11:08Z',
                        type: 'GET',
                        dataType: 'json',
                        beforeSend: function (xhr) {
                            xhr.setRequestHeader('Authorization', 'Bearer '+token+'');
                        },
                        data: {},
                        success: function (results) {                            
                            console.log(response);
                            debugger;
                        },
                        error: function (error) {
                            console.log("Error in getting data: " + error);
                        }
                    });
                }

            })
        }
    </script>
