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",
          "x-real-ip": "xxx",
          "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
    }
  }
