get_conf

err, value = qconf.get_conf(path, idc)

Description

get configure value

Parameters

path - key of configuration.

idc - Optional，from which idc to get the value，get from local idc if omit

Return Value

err - error code, 0 means success; others mean fail

value - if err == 0, then it is configure of current path; if err != 0, it is detailed information of current error code

Example

local err, value = qconf.get_conf(key)

get_batch_keys

err, value = qconf.get_batch_keys(path, idc);

Description

get all children nodes'key

Parameters

path - key of configuration.

idc - Optional，from which idc to get the keys，get from local idc if omit

Return Value

err - error code, 0 means success; others mean fail

value - if err == 0, then it is children nodes of current path; if err != 0, it is detailed information of current error code

Example

err, keys = qconf.get_batch_keys(key)

for 1, #(keys) in keys do

-- do something

done

get_batch_conf

err, value = qconf.get_batch_conf(path, idc);

Description

get all children nodes' key and value

Parameters

path - key of configuration.

idc - Optional， from which idc to get the children configurations，get from local idc if omit

Return Value

err - error code, 0 means success; others mean fail

value - if err == 0, then it is children nodes' key and value of current path; if err != 0, it is detailed information of current error code

Example

err, children = qconf.get_batch_conf(key)

for k, v in pairs(children) do

-- do something

done

get_allhost

err, value = qconf.get_allhost(path, idc);

Description

get all available services under given path

Parameters

path - key of configuration. idc - Optional， from which idc to get the services，get from local idc if omit

Return Value

err - error code, 0 means success; others mean fail

value - if err == 0, then it is available services of current path; if err != 0, it is detailed information of current error code

Example

err, hosts = qconf.get_allhost(key)

for 1, #(hosts) in hosts do

-- do something

done

get_host

err, value = qconf.get_host(path, idc);

Description

get one available service

Parameters

path - key of configuration.

idc - Optional，from which idc to get the host，get from local idc if omit

Return Value

err - error code, 0 means success; others mean fail

value - if err == 0, then it is one available service of current path; if err != 0, it is detailed information of current error code

Example

err, host = qconf.get_host(key)

	end
end

local err, keys = qconf.get_batch_keys(key)
if err == 0 then
	for v = 1, #(keys) do
		print(keys[v])
	end
end

local err, hosts = qconf.get_allhost(key)
if err == 0 then
	for v = 1, #(hosts) do
		print(hosts[v])
	end
end
