问题描述
如何使用 webhook 将图像插入到不和谐嵌入中.我将图像保存为从数据库中获取的 base64 字符串.我试过这个但是我只得到一个空嵌入
How do I insert an image into a discord embed using webhook. I have the image saved as a base64 string which I get from database. I have tried this but I only get an empty embed
const data = b64image.split(',')[1]; const buf = new Buffer.from(data, 'base64'); const file = new Discord.MessageAttachment(buf, 'img.jpeg'); const embed = new Discord.MessageEmbed() .setImage('attachment://img.jpeg') webhookClient.send('', { username: userName, embeds: [embed], });
推荐答案
我尝试使用较小的图像,问题中的代码有效.所以这是请求大小的问题.我通过设置一个快速路由来提供图像并使用嵌入中的 URL 来修复它
I tried with a smaller image, and the code in the question worked. So it was a problem with the size of the request. I fixed it by setting up an express route to serve images and used the URL in the embed
router.get('/thumb/:imgId', (req, res) => { const imgId = req.params.imgId.toString().trim(); let file = Buffer.from(b64Image.split(',')[1], 'base64') res.status(200); res.set('Content-Type', 'image/jpeg'); res.set('Content-Length', file.length) res.send(file) });
const embed = new Discord.MessageEmbed() .setImage(`${base_url}/img/thumb/${imgId}`) webhookClient.send('', { username: userName, embeds: [embed], });
