使用 f:read("*line") 读取字符，有时在拼接字符串时，会遇到后缀字符串覆盖前文的情况，根据分析应该lua读取的是个指针，所以附加字符串时会出现覆盖情况，
解决方式是 用 f:read("*all") 将文件一次性读取出来，然后分析字符串拆分
示例1：
function getFile(file_name)
local f = assert(io.open(file_name, 'r'))
local string = f:read("*line")
f:close()
return string
end
s = getFile("/home/faxfile/faxserver.ini")
print ("###/n"..s.."*****/n")
