小程序云开发与服务器对接

// 云函数示例：调用自建服务器API
const cloud = require('wx-server-sdk');
cloud.init();
const request = require('request');

exports.main = async (event, context) => {
  return new Promise((resolve, reject) => {
    request.get({
      url: 'https://your-server.com/api',
      headers: {
        'Content-Type': 'application/json'
      }
    }, (error, response, body) => {
      if (error) {
        reject(error);
      } else {
        resolve(JSON.parse(body));
      }
    });
  });
});

const express = require('express');
const cors = require('cors');

const app = express();

app.use(cors({
  origin: 'https://your-mini-program.com'
}));

app.get('/api', (req, res) => {
  res.json({ message: 'Hello from server!' });
});

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