如何使用node-soap服务器返回XML？

npm install soap

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

const server = http.createServer((req, res) => {
  res.end('Server is running');
});

const port = 3000;
server.listen(port, () => {
  console.log(`Server listening on port ${port}`);
});

const service = {
  MyService: {
    MyPort: {
      MyMethod: (args) => {
        // 在这里处理接收到的请求参数，并返回XML响应
        return {
          MyResponse: {
            Result: 'Success',
            Message: 'XML response generated successfully'
          }
        };
      }
    }
  }
};

const xml = require('fs').readFileSync('myservice.wsdl', 'utf8');
const server = http.createServer((req, res) => {
  res.end('Server is running');
});

const port = 3000;
server.listen(port, () => {
  console.log(`Server listening on port ${port}`);
  soap.listen(server, '/wsdl', service, xml);
});
