管理 Lambda 函数

创建 lambda 后，可以使用管理 API 查看它、更新支持的字段、列出账户中的所有 lambdas，或删除它。

函数结构

JavaScript lambdas 导出默认处理器。处理器接收请求对象，并返回希望 HolaCloud 发回的响应 body。

 1export default (req) => {
 2  return {
 3    body: {
 4      method: req.method,
 5      path: req.path,
 6      headers: req.headers,
 7      data: req.body
 8    }
 9  };
10};

静态 lambdas 使用一种静态语言模式：static-html、static-css 或 static-js。在这些模式中，code 是对应 lambda 提供的内容。

更新 Lambda

使用 PATCH /api/v0/lambdas/{lambda_id} 更新 name、language、code、method 或 path。

curl -X PATCH "https://api.hola.cloud/api/v0/lambdas/YOUR_LAMBDA_ID" \
  -H "X-Glue-Authentication: YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "hello-updated",
    "method": "POST",
    "path": "/hello-updated",
    "code": "export default (req) => ({ body: { message: \"Updated lambda\", data: req.body } })"
  }'
