File download not working or misunderstanding? #188

Closed smilebasti closed 5 months ago

smilebasti commented 5 months ago

Hello, i am trying to download my mails with imapflow.

I am using the following code:

const express = require('express');
const { createServer } = require('http');
const { ImapFlow } = require('imapflow');
const fs = require('fs');

const app = express();
const server = createServer(app);
const port = 8080;

const imapConfig = {
    host: 'imap.goneo.de',
    port: 993,
    secure: true,
    auth: {
        user: 'marianne@wieser-hv.de',
        pass: 'Sebastian31!'
    }
};

app.get('/', async (req, res) => {
    try {
        const client = new ImapFlow(imapConfig);

        await client.connect();

        let lock = await client.getMailboxLock('INBOX');

        //const message = await client.fetchOne('1', { source: true });
        //console.log(message.source.toString());
        console.log('Before download.');

        let { meta, content } = await client.download('1');

        console.log('meta.filename: ' + meta.filename);

        content.pipe(fs.createWriteStream(meta.filename));

        console.log('After download.');
        console.log(meta.filename);
        lock.release();
        await client.logout();

        res.json(message.source.toString());

    } catch (error) {
        console.error(error);
        res.status(500).json({ error: 'Internal Server Error' });
    }

    // log out and close connection

});

server.listen(port, () => {
    console.log("Server is running on http://localhost:" + port);
});

But i am only getting this error when i open the site:

Server is running on http://localhost:8080

I am not sure where my error lives? I can't figure out why my meta.filename is empty....

Any help would be greatly appreciated :).

You are downloading the entire EML file. There is no filename set for it. Filename applies for attachments only.

Thank you very much @andris9. It works, partially... When i execute it with a predefined file name it works till the command await client.logout();. Then the download fails with:

My current Code:

const express = require('express');
const { createServer } = require('http');
const { ImapFlow } = require('imapflow');
const fs = require('fs');

const app = express();
const server = createServer(app);
const port = 8080;

const client = new ImapFlow({
    host: 'imap.goneo.de',
    port: 993,
    secure: true,
    auth: {
        user: 'marianne@wieser-hv.de',
        pass: 'Sebastian31!'
    }
});

app.get('/', async (req, res) => {
    await client.connect();
    try {

        let lock = await client.getMailboxLock('INBOX');

        console.log('Before download.');

        let { meta, content } = await client.download('1');
        content.pipe(fs.createWriteStream('testname.eml'));

        console.log('After download.');
        lock.release();

        res.json('Test Message');

    } catch (error) {
        console.error(error);
        res.status(500).json({ error: 'Internal Server Error' });
    }
    finally{
        //await client.logout();
        console.log('After logout');
    }

});

server.listen(port, () => {
    console.log("Server is running on http://localhost:" + port);
});

How would i go about it to check if the download is complete and then logout?
