在node js中将镜像从客户端发送到服务器端

const http = require('http');
const fs = require('fs');

const server = http.createServer((req, res) => {
  // 处理客户端发送的镜像
  if (req.url === '/upload' && req.method === 'POST') {
    // 创建一个可写流，用于保存接收到的镜像
    const fileStream = fs.createWriteStream('uploaded_image.jpg');
    req.pipe(fileStream);

    // 监听可写流的finish事件，表示镜像接收完成
    fileStream.on('finish', () => {
      res.statusCode = 200;
      res.end('Image uploaded successfully');
    });
  } else {
    res.statusCode = 404;
    res.end('Not found');
  }
});

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

const http = require('http');
const fs = require('fs');

// 读取要上传的镜像文件
const imageFileStream = fs.createReadStream('image.jpg');

// 构建HTTP请求选项
const options = {
  hostname: 'localhost',
  port: 3000,
  path: '/upload',
  method: 'POST',
  headers: {
    'Content-Type': 'image/jpeg',
  },
};

// 发送HTTP请求
const req = http.request(options, (res) => {
  res.on('data', (data) => {
    console.log(data.toString());
  });
});

// 将镜像数据作为请求体发送
imageFileStream.pipe(req);
