如何让 discord 机器人发送抓取的消息？

Question

I want to make an a discord bot that sends a scraped message. I expected it to send the message but it gave me an error:

throw new DiscordAPIError(request.path, data, request.method, res.status); DiscordAPIError: Cannot send an empty message

I tried to use message.channel.send(); but it doesn't seem to work. Code:

let data = await page.evaluate(() => {
            let Name = document.querySelector('div[id="title"]').innerText;
            let Description = document.querySelector('div[id="content"]').innerText;
            return {
                Name,
                Description
            }
        });
        console.log(data);
        message.channel.send(data);
        debugger;
        await browser.close();

The problem is that you shouldn't send the dictionary directly. While message.channel.send only accepts StringResolvable or APIMessage , data as a dictionary is neither. For more information, see the documentation .

Instead, you can convert data to a string first. The following is one of the solutions.

// Convert using JSON.stringify
message.channel.send(JSON.stringify(data));

Full code example (I tried it on https://example.com and thus there are different queries):

let data = await page.evaluate(() => {
    let Name = document.querySelector('h1').innerText;
    let Description = document.querySelector('p').innerText;
    return {
        Name,
        Description
    }
});
console.log(data);
message.channel.send(JSON.stringify(data));

Message sent by the bot without errors being thrown:

{"Name":"Example Domain","Description":"This domain is for use in illustrative examples in documents. You may use this domain in literature without prior coordination or asking for permission."}

If you expect a different message, just make sure that the argument you are passing to message.channel.send is acceptable or errors might be thrown.
