如何使用 Microsoft Graph 客户端作为其他用户从 Microsoft Teams Bot 发送电子邮件？

Question

我的机器人嵌入了 LUIS。 如果 LUIS 无法接听或无法理解用户的问题，我希望机器人发送一封电子邮件，请求相关人员提供帮助。

这是我迄今为止尝试过的

const { ComponentDialog, WaterfallDialog, ConfirmPrompt } = require('botbuilder-dialogs');
const { ActivityTypes } = require("botbuilder");

const path = require('path');
require('dotenv').config({
   path: path.resolve('.env'),
});

const { ClientSecretCredential } = require("@azure/identity");

const { Client } = require("@microsoft/microsoft-graph-client");

const { TokenCredentialAuthenticationProvider } = require("@microsoft/microsoft-graph-client/authProviders/azureTokenCredentials");

let appInsights = require('applicationinsights');
appInsights.setup(process.env.APPINSIGHTS_INSTRUMENTATIONKEY).start();

const CONFIRM_PROMPT = 'ConfirmPrompt';
const HELP_DIALOG = 'WaterfallDialog'

class HelpDialog extends ComponentDialog {

    constructor(id) {
        super(id);

        this.addDialog(
            new WaterfallDialog(HELP_DIALOG ,[
                this.getHelp.bind(this),
                this.sendEmail.bind(this)
            ]))
            .addDialog(new ConfirmPrompt(CONFIRM_PROMPT));

        this.initialDialogId = HELP_DIALOG;

    }

    async getHelp(stepContext) {
        await stepContext.context.sendActivity({ type: ActivityTypes.Typing });
        return await stepContext.prompt(CONFIRM_PROMPT, "I'm not sure what you are asking for, would you like me to get extra help?", ['Yes', 'No']);
    }

    async sendEmail(stepContext) {

        if(stepContext.result) {

            // Create TokenCredential
            const credential = new ClientSecretCredential(process.env.MicrosoftTenantID, process.env.MicrosoftAppId, process.env.MicrosoftAppPassword);

            // Set scope for TokenCredential
            const graphScope = 'https://graph.microsoft.com/.default';
            const authProvider = new TokenCredentialAuthenticationProvider(credential, { scopes: [graphScope] });

            // Create client for TokenCredential
            const graphClient = Client.initWithMiddleware({
                debugLogging: true,
                authProvider,
            });

            // Construct email object
            const mail = {
                subject: "Unknown Bot Questions",
                toRecipients: [
                {
                    emailAddress: {
                        address: "receiver@outlook.com",
                    },
                }],
                body: {
                    content: `<p>Hello,</p><p>I am having trouble querying the following questions to the Bot.</p><p>I need some assistance for the above queries.</p><p>Thanks</p>`,
                    contentType: "html",
                },
            };
            //Send Email
            await graphClient.api('https://graph.microsoft.com/v1.0/users/<ObjectId-Mailbox>/sendMail')
            .post(mail)
            .then((res) => {
                console.log(res);
            })
            .catch((res) => {
                console.log(res);
            });

            return await stepContext.endDialog(stepContext.options);
        }
        else
        {
            return await stepContext.endDialog(stepContext.options);
        }
    }

}

module.exports.HelpDialog = HelpDialog;

我在另一个对话框中使用TeamsBotSsoPrompt和microsoft-graph-client进行了身份验证设置， graphClient在我想从中发送电子邮件的对话框中使用了graphClient实例。 但我希望电子邮件从一个公共电子邮件地址发送，而不是接收者从多个用户接收电子邮件。

若要从常用电子邮件地址发送电子邮件，首先需要在 Azure AD 中创建应用程序注册。

在API 权限选项卡中，选择Microsoft Graph ，然后选择应用程序权限，然后添加Mail.Send权限。

记下您的应用程序注册的客户端 ID，然后通过单击Certificates and secrets创建一个客户端机密，创建一个机密，然后记下。

我不确定您如何存储和检索客户端 ID、机密、密钥等，但在我的环境中，我使用的是 env 文件，并且还安装了@azure/identity包，所以我的看起来像有点像这样。

 const path = require('path');
   require('dotenv').config({
   path: path.resolve('.env'),
 });

 const {
   ClientSecretCredential
 } = require("@azure/identity");

 const {
   Client
 } = require("@microsoft/microsoft-graph-client");

 const {
   TokenCredentialAuthenticationProvider
 } = require("@microsoft/microsoft-graph- 
   client/authProviders/azureTokenCredentials");

 // Create TokenCredential
 const credential = new 
   ClientSecretCredential(process.env.MicrosoftTenantID, process.env.MicrosoftAppId, process.env.MicrosoftAppPassword);

 // Set scope for TokenCredential
 const graphScope = 'https://graph.microsoft.com/.default';
 const authProvider = new TokenCredentialAuthenticationProvider(credential, 
   {
    scopes: [graphScope]
    });

 // Create client for TokenCredential
 const graphClient = Client.initWithMiddleware({
    debugLogging: true,
    authProvider,
 });

有了这个，我检索了我想从中发送电子邮件的用户/邮箱的对象 ID，并进行图形调用以发送电子邮件。

await graphClient.api('https://graph.microsoft.com/v1.0/users/4ae760e0-8040-4cf1-a630-941c1240f7b0/sendMail')
.post(mail)
.then((res) => {
   console.log(res);
                    })
.catch((res) => {
   console.log(res);
});

我想有很多更好的方法可以实现这一点，但这对我有用。
