   org: test # Organization information, which is optional. The default value is the `appid` of your Tencent Cloud account
   app: scfApp # SCF application name, which is optional
   stage: dev # Information for identifying environment, which is optional. The default value is `dev`
   inputs:
   name: scfFunctionName
   src: ./src
   runtime: Nodejs10.15 # Runtime environment of function. Valid values: Python2.7, Python3.6, Nodejs6.10, Nodejs8.9,Nodejs12.16, Nodejs10.15, PHP5, PHP7, Golang1, Java8.
   region: ap-guangzhou
