函数-j9九游会登录

配置

# serverless.yml
service: fg-service
provider:
  name: huawei
plugins:
  - serverless-huawei-functions
functions:
  first:
    handler: index.handler

执行入口

handler属性应该是您在入口文件中导出的函数名称。

// index.js
exports.handler = (event, context, callback) => {};

内存大小和超时

函数的memorysize和timeout可以在提供商或函数层面指定。提供商层面的定义允许所有函数共享此配置，而函数层面的定义意味着此配置仅对当前函数有效。

# serverless.yml
provider:
  memorysize: 512
  timeout: 90
functions:
  first:
    handler: first
  second:
    handler: second
    memorysize: 256
    timeout: 60

执行入口签名

function (event, context) { }

• event

  如果函数由指定的apig事件触发，则传递给执行入口的event如下：

  // json.parse(event)
  {
    events: {
      "body": "",
      "requestcontext": {
          "apiid": "xxx",
          "requestid": "xxx",
          "stage": "release"
      },
      "querystringparameters": {
          "responsetype": "html"
      },
      "httpmethod": "get",
      "pathparameters": {},
      "headers": {
          "accept-language": "zh-cn,zh;q=0.8,zh-tw;q=0.7,zh-hk;q=0.5,en-us;q=0.3,en;q=0.2",
          "accept-encoding": "gzip, deflate, br",
          "x-forwarded-port": "443",
          "x-forwarded-for": "xxx",
          "accept": "text/html,application/xhtml xml,application/xml;q=0.9,*/*;q=0.8",
          "upgrade-insecure-requests": "1",
          "host": "xxx",
          "x-forwarded-proto": "https",
          "pragma": "no-cache",
          "cache-control": "no-cache",

          "user-agent": "mozilla/5.0 (windows nt 6.1; win64; x64; rv:57.0) gecko/20100101 firefox/57.0"
      },
      "path": "/apig-event-template",
      "isbase64encoded": true
    }
  }

• context

  context参数包含有关函数的运行时信息。例如：请求id、临时ak、函数元数据。具体详情请参见开发事件函数。
