首先安装内置青云SDK的 qlua 命令: go get github.com/chai2010/qingcloud-go/cmd/qlua

注：这个解释器不是官方的C语言版本Lua解释器，而且纯Go语言实现的 解释器订制而来。

创建一个JSON格式的配置文件，里面含有基本是口令信息 ~/.qingcloud/qcli.json:

{	"api_server": "https://api.qingcloud.com/iaas/",	"access_key_id": "公钥",	"secret_access_key": "私钥",	"zone": "pek3a"}

然后创建 hello.lua 脚本:

local qc = require("qingcloud.iaas")if #arg == 1 and arg[1] == '-v' then	print(qc.version)	print(qc.version_info.git_sha1_version)	print(qc.version_info.build_date)	do return endendif #arg == 1 and arg[1] == '-h' then	print(qc.copyright)	print("hello, 青云!")	do return endendlocal config = qc.LoadJSON("~/.qingcloud/qcli.json")local client = qc.Client:new(config)local reply, err = client:DescribeInstances {	--owner = "usr-xxxxxxxx",	zone = "pek3a",	limit = 100}if err ~= nil then	print("error:", err)	do return endendif reply.ret_code ~= 0 then	print(reply.ret_code)	print(reply.message)	do return endendfor i = 1, #reply.instance_set do	local item = reply.instance_set[i]	print(i,		item.instance_id,		item.instance_type,		item.memory_current..'MB',		item.status,		item.create_time,		item.instance_name	)endprint('total: ' .. reply.total_count)

可以输入一下命令执行:

$ qlua hello.lua -h$ qlua hello.lua -v$ qlua hello.lua

如果虚机数量巨大，则需要多次调用 client:DescribeInstances 获取。
