⚡ Lambda

无服务器函数执行平台

Lambda 在 HolaCloud 上通过 HTTP endpoint 运行 JavaScript 函数和静态资源。

开始使用文档中心

Lambda

核心功能

通过 Lambda API 创建、更新、列出、删除并调用 HTTP 函数。

JavaScript 函数

使用内置运行时 helper，例如 write、body、query 和 headers。

HTTP 调用

通过公共运行 URL、认证的管理运行 URL，或按 owner/project 的 mux 路由调用函数。

静态响应

用同一套 Lambda 模型提供静态 HTML、CSS 和 JavaScript 片段。

Quick start

快速开始

使用 API 在几秒内开始使用 Lambda。

curl -X POST https://api.hola.cloud/api/v0/lambdas \
  -H 'X-Glue-Authentication: {"user":{"id":"user-123"}}' \
  -d '{"name":"hello","language":"javascript","method":"GET","path":"/hello","code":"write(\"Hello from Lambda\")"}'

POST /api/v0/lambdas HTTP/1.1
Host: api.hola.cloud
X-Glue-Authentication: {"user":{"id":"user-123"}}

{"name":"hello","language":"javascript","method":"GET","path":"/hello","code":"write(\"Hello from Lambda\")"}

package main

import (
	"fmt"
	"io"
	"net/http"
	"encoding/json"
	"strings"
)

func main() {
	payload := map[string]any{"code": "write(\"Hello from Lambda\")", "language": "javascript", "method": "GET", "name": "hello", "path": "/hello"}
	bodyBytes, err := json.Marshal(payload)
	if err != nil {
		panic(err)
	}
	body := string(bodyBytes)

	req, err := http.NewRequest("POST", "https://api.hola.cloud/api/v0/lambdas", strings.NewReader(body))
	if err != nil {
		panic(err)
	}
	req.Header.Set("X-Glue-Authentication", "{\"user\":{\"id\":\"user-123\"}}")

	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	responseBody, err := io.ReadAll(resp.Body)
	if err != nil {
		panic(err)
	}
	fmt.Println(string(responseBody))
}
