使用函数服务的 SDK 可以更加便捷地执行创建函数、上传代码和管理触发器等操作。本文介绍 Node.js SDK 的使用案例。

使用须知

目前还没有正式支持 Node.js SDK。
如果需要使用 Node.js SDK，可以通过@volcengine/vcloud-core实现鉴权逻辑后请求 OpenAPI。

安装依赖

npm install @volcengine/vcloud-core
npm install axios

创建「微服务应用」-通过函数模板部署代码

const { Signer } = require("@volcengine/vcloud-core");
const axios = require("axios");

const version = "2024-06-06"; // API Version
const serviceName = "vefaas"; // ServiceName
const apiHost = "open.volcengineapi.com"; // OpenAPI host

class CustomClient {
  constructor(options) {
    this.instance = this.axiosRequest(options);
  }

  axiosRequest(options) {
    const {
      region,
      accessKey,
      secretKey,
      host,
      headers,
      serviceName,
      version,
    } = options;
    const baseURL = "http://" + host;

    const instance = axios.create({
      baseURL: baseURL,
      method: "POST",
      params: { Version: version },
      headers,
    });

    instance.interceptors.request.use((config) => {
      const requestInfo = {
        region: region,
        method: config.method || "POST",
        pathname: "/",
        params: config.params || {},
        body: config.data,
        headers: config.headers,
      };

      const signer = new Signer(requestInfo, serviceName);

      signer.addAuthorization(
        {
          accessKey,
          secretKey,
        },
        new Date()
      );

      return config;
    });

    instance.interceptors.response.use(
      (config) => {
        console.log(config.data);

        return config.data;
      },
      (err) => {
        console.log(
          "Response Error: ",
          err?.response?.data?.ResponseMetadata?.Error?.Message ||
            err?.response?.data
        );

        const errorMessage =
          err?.response?.data?.ResponseMetadata?.Error?.Message;

        return Promise.reject(errorMessage);
      }
    );

    return instance;
  }

  async CreateFunction(params) {
    return await this.instance.request({
      data: params,
      params: { Action: "CreateFunction" },
    });
  }
}

const client = new CustomClient({
  region: "cn-beijing",
  accessKey: "yourAccessKeyId",
  secretKey: "yourAccessKeySecret",
  host: apiHost,
  serviceName,
  version,
});

client
  .CreateFunction({
    Name: "micro-service-doctest",
    Runtime: "native/v1",
    VpcConfig: {
      EnableVpc: true,
      VpcId: "vpc-id",
      SubnetIds: ["subnet-id"],
      SecurityGroupIds: ["sg-id"],
    },
    Command: "./run.sh",
    CpuStrategy: "always",
  })
  .then((res) => {
    console.log(res, "response");
  })
  .catch((err) => {
    console.error(err, "error");
  });

请根据业务真实情况配置代码参数，可参考文档CreateFunction，下表只介绍创建微服务应用时的特殊配置。

结果验证

通过 SDK 创建函数后，您可以登录函数服务控制台查看是否成功创建函数，微服务应用的CPU 分配模式固定为始终分配。
