在MongoDB Atlas Functions中使用axios报错求助

问题详情 #

已在MongoDB Atlas Functions中成功添加axios依赖，但运行以下函数时触发报错：

exports = function() {
  const axios = require("axios");
axios.get('https://api.github.com/users/PowellTravis/repos?per_page=100&page=1')
  .then(function (response) {
    onSuccess(response)
  })
  .catch(function (error) {
    console.log(error);
  });
}

报错信息：

解决办法 #

有两种可行方案：

1. 降级axios版本
   安装axios的0.27.2版本，这是最后一个不依赖Node.js核心zlib模块Z_SYNC_FLUSH属性的稳定版本。MongoDB Atlas Functions的沙箱环境限制了对该属性的访问，高版本axios会因无法调用该属性而加载失败。

2. 使用内置fetch API替代axios
   MongoDB Atlas Functions原生支持fetch，无需额外依赖，代码示例：

   exports = async function() {
     try {
       const response = await fetch('https://api.github.com/users/PowellTravis/repos?per_page=100&page=1');
       const repoData = await response.json();
       return repoData;
     } catch (err) {
       console.error('请求失败:', err);
       throw err;
     }
   };
   

错误原因 #

Z_SYNC_FLUSH是Node.js zlib模块的一个常量，高版本axios（如v1.x系列）的HTTP适配器会尝试调用这个常量。但MongoDB Atlas Functions的运行环境是受限的沙箱，并未开放对该核心模块属性的访问权限，导致axios加载时触发类型错误。
