微信小程序码生成

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

// 微信小程序的AppID和AppSecret
const appId = 'your_app_id';
const appSecret = 'your_app_secret';

// 获取access_token
async function getAccessToken() {
  const response = await axios.get(`https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=${appId}&secret=${appSecret}`);
  return response.data.access_token;
}

// 生成小程序码
async function generateMiniProgramCode(page, scene) {
  const accessToken = await getAccessToken();
  const response = await axios.post(`https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=${accessToken}`, {
    scene,
    page,
  }, {
    responseType: 'stream',
  });

  // 将生成的小程序码保存到文件
  const writer = fs.createWriteStream('mini_program_code.png');
  response.data.pipe(writer);

  return new Promise((resolve, reject) => {
    writer.on('finish', resolve);
    writer.on('error', reject);
  });
}

// 调用示例
generateMiniProgramCode('pages/index/index', '123').then(() => {
  console.log('小程序码生成成功！');
}).catch((error) => {
  console.error('小程序码生成失败：', error);
});
