小程序开发图片数据放到服务器

// 示例代码：使用Node.js和Express上传图片到服务器
const express = require('express');
const multer = require('multer');
const app = express();

const storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, 'uploads/');
  },
  filename: function (req, file, cb) {
    cb(null, Date.now() + '-' + file.originalname);
  }
});

const upload = multer({ storage: storage });

app.post('/upload', upload.single('image'), (req, res) => {
  if (!req.file) {
    return res.status(400).send('No file uploaded.');
  }
  res.send('File uploaded successfully.');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

// 示例代码：使用腾讯云COS加速图片加载
const COS = require('cos-nodejs-sdk-v5');
const cos = new COS({
  SecretId: 'YOUR_SECRET_ID',
  SecretKey: 'YOUR_SECRET_KEY',
});

cos.getBucket({
  Bucket: 'YOUR_BUCKET_NAME'
}, (err, data) => {
  if (err) {
    console.error(err);
  } else {
    console.log(data);
  }
});
