操作运行(使用easyfaas函数计算服务)

安装运行完成后，即可进行下一步

1. 创建函数

使用stub组件构建本地代码仓库其创建函数接口API详见接口API文档, 可以使用curl或者其他工具如Paw发起创建函数请求。

1.1 编写函数代码

首先编写一个简单的nodejs10的hello world 函数代码,代码存储在index.js文件中 备注： 您也可以直接跳过此步骤，直接运行1.1和1.2，直接运行1.3

  1. $ cat index.js 
  2. exports.handler = (event, context, callback) => {
  3.     callback(null, "Hello world!");
  4. };

1.2 打包函数代码并获得其base64编码

  1. $ zip code.zip index.js 
  2. $ base64 code.zip 
  3. UEsDBBQAAAAIAAxDX00vNEyNUAAAAFgAAAAIABwAaW5kZXguanNVVAkAA/ie2VuKQthfdXgLAAEE
  4. 6AMAAAToAwAAS60oyC8qKdbLSMxLyUktUrBV0EgtS80r0VFIzs8rSa0AMRJzcpISk7M1FWztFKq5
  5. FIAAJqSRV5qTo6Og5JGak5OvUJ5flJOiqKRpzVVrDQBQSwECHgMUAAAACAAMQ19NLzRMjVAAAABY
  6. AAAACAAYAAAAAAABAAAApIEAAAAAaW5kZXguanNVVAUAA/ie2Vt1eAsAAQToAwAABOgDAABQSwUG
  7. AAAAAAEAAQBOAAAAkgAAAAAA

1.3 调用func-registry创建函数接口创建函数

请求body中Code字段填入上一步骤中获得的base64编码

  1. $ curl -X POST "http://<YOUR_IP>:<YOUR_FUNC_REGISTRY_PORT>/v1/functions/testHelloWorld" -d '{"Version":"1","Description":"stubs create","Runtime":"nodejs10","Timeout":5,"MemorySize":128,"Handler":"index.handler","PodConcurrentQuota":10,"Code":"UEsDBBQAAAAAAHCjX00AAAAAAAAAAAAAAAAJABUAX19NQUNPU1gvVVgIALSf2Vu0n9lbVVQFAAG0n9lbUEsDBBQACAAIAAyjX00AAAAAAAAAAAAAAAATABUAX19NQUNPU1gvLl9pbmRleC5qc1VYCACwn9lb+J7ZW1VUBQAB+J7ZW2JgFWNnYGJg8E1MVvAPVohQgAKQGAMnAwODEQMDQx0DA5i/gYEo4BgSEgRlgnQsYGBgEEBTwogQl0rOz9VLLCjISdXLSSwuKS1OTUlJLElVDggGKXw772Y0iO5J8tAH0YAAAAD//1BLBwgOCcksZgAAALAAAABQSwMEFAAIAAgAAAAAAAAAAAAAAAAAAAAAAAgAAABpbmRleC5qc0qtKMgvKinWy0jMS8lJLVKwVdBILUvNK9FRSM7PK0mtADESc3KSEpOzNRVs7RSquRQUFOBCGnmlOTk6CkoeqTk5+Qrl+UU5KYpKmtZctdaAAAAA//9QSwcILzRMjVUAAABYAAAAUEsBAhQDFAAAAAAAcKNfTQAAAAAAAAAAAAAAAAkAFQAAAAAAAAAAQP1BAAAAAF9fTUFDT1NYL1VYCAC0n9lbtJ/ZW1VUBQABtJ/ZW1BLAQIUAxQACAAIAAyjX00OCcksZgAAALAAAAATABUAAAAAAAAAAECkgTwAAABfX01BQ09TWC8uX2luZGV4LmpzVVgIALCf2Vv4ntlbVVQFAAH4ntlbUEsBAhQAFAAIAAgAAAAAAC80TI1VAAAAWAAAAAgAAAAAAAAAAAAAAAAA+AAAAGluZGV4LmpzUEsFBgAAAAADAAMA2AAAAIMBAAAAAA=="}' -H 'X-easyfaas-Account-Id: df391b08c64c426a81645468c75163a5'   -H 'Content-Type: application/json; charset=utf-8'
