使用 Microsoft Graph 创建日历事件:ErrorAccessDenied [英] Create calendar event using Microsoft Graph: ErrorAccessDenied

问题描述

我一直在使用 curl 和 Outlook REST API v1.0(带有基本身份验证)在 Outlook 日历中创建日历事件.基本身份验证即将被弃用，因此我现在尝试使用 OAuth 2 迁移到 Microsoft Graph v1.0.我已经取得了一些进展，但在运行 POST 以创建事件时卡在ErrorAccessDenied".这是我到目前为止所做的:

I've been using curl and the Outlook REST API v1.0 (with basic authentication) to create calendar events in Outlook calendars. Basic authentication is soon being deprecated so I am now trying to migrate to Microsoft Graph v1.0 with OAuth 2. I have got some way down the road but am stuck at "ErrorAccessDenied" when running the POST to create the event. This is what I've done so far:

1. 在此处注册了我的应用程序(curl):https://apps.dev.microsoft.com/#/appList，将 Application Permissions 设置为 Calendars.ReadWrite(并且，为了更好地衡量，Delegated Permissions 也设置为 Calendars.ReadWrite.)

1. Registered my app (curl) here: https://apps.dev.microsoft.com/#/appList, setting Application Permissions to Calendars.ReadWrite (and, for good measure, Delegated Permissions to Calendars.ReadWrite as well.)

使用上面第 1 步中的客户端/应用程序 ID 和客户端密码/密码，我可以使用以下命令获取访问令牌:

Using the client/application ID and client secret/password from step 1 above, I can get an access token using this command:

curl -X POST -k -d "grant_type=client_credentials&client_id=[ApplicationID]&client_secret=[Password]&resource=https%3A%2F%2Fgraph.microsoft.com%2F" https://login.microsoftonline.com/[TenantID]/oauth2/token

curl -X POST -k -d "grant_type=client_credentials&client_id=[ApplicationID]&client_secret=[Password]&resource=https%3A%2F%2Fgraph.microsoft.com%2F" https://login.microsoftonline.com/[TenantID]/oauth2/token

1. 然后我尝试使用以下命令创建一个事件，但得到下面的 ErrorAccessDenied 错误:

curl.exe -k -o "C:Tempoutput.txt" -X POST -H "Content-Type:application/json" -H "Authorization: Bearer [TOKEN]" -d @"C:TempeventDetails.json" https:///graph.microsoft.com/v1.0/users/[UserPrincipalName]/calendars/[CalendarID]/events?$select=Id,lastModifiedDateTime

curl.exe -k -o "C:Tempoutput.txt" -X POST -H "Content-Type:application/json" -H "Authorization: Bearer [TOKEN]" -d @"C:TempeventDetails.json" https://graph.microsoft.com/v1.0/users/[UserPrincipalName]/calendars/[CalendarID]/events?$select=Id,lastModifiedDateTime

{错误": {"code": "ErrorAccessDenied","message": "访问被拒绝.检查凭据并重试.",内部错误":{请求 ID":38b802b9-08b9-4e0b-8f91-66ef56c459f8"，日期":2018-10-17T01:08:22"}}}

{ "error": { "code": "ErrorAccessDenied", "message": "Access is denied. Check credentials and try again.", "innerError": { "request-id": "38b802b9-08b9-4e0b-8f91-66ef56c459f8", "date": "2018-10-17T01:08:22" } } }

除了将已注册应用的应用程序权限设置为 Calendars.ReadWrite(上面的第 1 步)之外，我不知道如何允许访问.任何帮助将不胜感激.

Beyond setting the registered app's Application Permissions to Calendars.ReadWrite (step 1 above) I'm at a loss on how to allow access. Any help would be greatly appreciated.

谢谢.

推荐答案

对我有很大帮助的是使用 JWT 检查网站检查令牌，例如 JWT.ms.本网站将向您解释有关令牌的所有详细信息(由 Microsoft 构建，令牌仅由 javascript 解析，不传输).该网站还有一个Claims选项卡，其中解释了令牌中的所有声明.

What helped me greatly is inspecting the token with a JWT inspecting website, like JWT.ms. This website will explain all the details to you about the token (it is build by Microsoft, the token only gets parsed by javascript and isn't transmitted). This website also has a Claims tab, where they explain all the claims in the token.

您正在谈论应用程序权限，这需要一个额外的步骤.它还必须得到 Azure AD 管理员的同意才能访问您要访问的目录.

You're talking about application permissions, that requires an extra step. It also has to be consented by an Azure AD Administrator for the directory you want to access.

您可以将其构建到登录流程中，但最简单的方法是通过 Azure 门户.

You can build this into the sign-in flow, but the easiest way is through the Azure Portal.

1. 转到 https://portal.azure.com -> Azure Active Directory -> [AD 名称] - 应用注册
2. 找到您要授予访问权限的应用.
3. 点击设置
4. 点击所需权限
5. 点击授予权限

1. Go to https://portal.azure.com -> Azure Active Directory -> [AD Name] - App registrations
2. Find the app you want to grant access to.
3. Click Settings
4. Click Required Permissions
5. Click Grant Permissions

这样做是在您的租户中创建一个具有您请求的权限的应用程序帐户.

What this does is creating an application account in your tenant, with the permissions you requested.

在这些步骤之后，您应该创建一个新令牌并将其与您第一次获得的令牌进行比较，您应该能够看到更改.

After these steps you should create a new token and compare it to the token you got the first time, and you should be able to see the changes.
