Execute

Execution is for activities of type req. When the server generates a req activity, it is in an interrupted state, waiting for the client to execute.

Env

Each command execution requires some options parameters. This command generates the options parameters needed for subsequent execution actions.

env <op> [key] [value] [value-type]
    op: command with set, get, ls
            set: set key and value.
            get: get by key name
            ls: list all env values
            json: show in json format
    key: env key with string type
    value: env value
    value-type: value type with string, int, float and json, the default type is string
