--- 启动远程升级功能
|
||||
-- @function[opt=nil] cbFnc 每次执行远程升级功能后的回调函数，回调函数的调用形式为：
|
||||
-- cbFnc(result)，result为true表示升级包下载成功，其余表示下载失败
|
||||
--如果没有设置此参数，则升级包下载成功后，会自动重启
|
||||
-- @string[opt=nil] url 使用http的get命令下载升级包的url，如果没有设置此参数，默认使用Luatiot平台的url
|
||||
-- 如果用户设置了url，注意：仅传入完整url的前半部分(如果有参数，即传入?前一部分)，http.lua会自动添加?以及后面的参数，例如：
|
||||
-- 设置的url="www.userserver.com/api/site/firmware_upgrade"，则http.lua会在此url后面补充下面的参数
|
||||
-- "?project_key=".._G.PRODUCT_KEY
|
||||
-- .."&imei="..misc.getimei()
|
||||
-- .."&device_key="..misc.getsn()
|
||||
-- .."&firmware_name=".._G.PROJECT.."_"..rtos.get_version().."&version=".._G.VERSION
|
||||
-- 如果用户设置了url，且url前面增加三个井号"###",http.lua会自动忽略"###"并以用户填入的url作为请求地址，不会自动添加模块信息，例如：
|
||||
-- 设置的url="###www.userserver.com"/api/site/firmware_upgrade?customparam=test",则http.lua会将此url开头的"###"忽略,并以此url为地址进行请求
|
||||
-- "www.userserver.com"/api/site/firmware_upgrade?customparam=test"
|
||||
-- 如果redir设置为true，还会补充.."&need_oss_url=1"
|
||||
-- @number[opt=nil] period 单位毫秒，定时启动远程升级功能的间隔，如果没有设置此参数，仅执行一次远程升级功能
|
||||
-- @bool[opt=nil] redir 是否访问重定向到阿里云的升级包，使用Luat提供的升级服务器时，此参数才有意义
|
||||
-- 为了缓解Luat的升级服务器压力，从2018年7月11日起，在iot.openluat.com新增或者修改升级包的升级配置时，升级文件会备份一份到阿里云服务器
|
||||
-- 如果此参数设置为true，会从阿里云服务器下载升级包；如果此参数设置为false或者nil，仍然从Luat的升级服务器下载升级包

-- step表示下载进度：取值范围是0到100，下载进度更新很快，建议在回调函数中，每隔5或者10执行一次实际动作

--- 获取请求升级包时服务器返回的信息
|
