从图形获取单个消息

Question

我正在尝试从 Office 365 邮箱获取一封电子邮件。

我通过 POST ( req.body.id ( 将电子邮件id发送到我的应用程序，然后调用此代码以获取一些电子邮件属性：

router.post('/id', async function(req, res, next) {
    console.log("email with ID -> ", req.body.id)
    let parms = { title: 'Inbox', active: { inbox: true } };
    const accessToken = await authHelper.getAccessToken(req.cookies, res);
    const userName = req.cookies.graph_user_name;
    if (accessToken && userName) {
    parms.user = userName;
    // Initialize Graph client
    const client = graph.Client.init({
        authProvider: (done) => {
        done(null, accessToken);
        }
    });
    try {
        const result = await client
        .api('/me/messages/', req.body.id)
        .select('id,subject,from,toRecipients,ccRecipients,body,sentDateTime,receivedDateTime')
        .get();
        parms.messages = result.value;
        console.log("email -> ", result.value);
        res.render('message', parms);
    } catch (err) {
        parms.message = 'Error retrieving messages';
        parms.error = { status: `${err.code}: ${err.message}` };
        parms.debug = JSON.stringify(err.body, null, 2);
        res.render('error', parms);
        }
    } else {
    // Redirect to home
    res.redirect('/');
    }
});

目前，result.value包含邮箱中的所有邮件，而不仅仅是具有提供id的邮件。

有人可以告诉我我的错误在哪里吗？

api方法具有单个路径参数。像.api('/me/messages/', req.body.id)一样调用它实际上是向它发送路径("/me/messages/"(以及它忽略的附加参数。

您需要

向其发送单个字符串，因此您需要将req.body.id附加到路径 ( {path} + {id} (：

const result = await client
  .api('/me/messages/' + req.body.id)
  .select('id,subject,from,toRecipients,ccRecipients,body,sentDateTime,receivedDateTime')
  .get();
