lua代码保存内容到文件

function io.writefile(path, content, mode)
    mode = mode or "w+b"
    local file = io.open(path, mode)
    if file then
        if file:write(content) == nil then return false end
        io.close(file)
        return true
    else
        return false
    end
end

io.writefile(path .. '/test/' .. 'input_' .. output, input)
