深圳力维智联技术有限公司1月招聘面试题面试题面试官常问到的一些题目整理如下:问题 Q1:如何提高爬取效率?可用的回答 : 爬虫下载慢主要原因是阻塞等待发往网站的请求和网站返回 1,采用异步与多线程,扩大电脑的cpu利用率; 2,采用消息队列模式 3,提高带宽 问题 Q2:简述一下scrapy的基本流程?可用的回答 : scrapy分为9个步骤: 1. Spiders需要初始的start_url或则函数stsrt_requests,会在内部生成Requests给Engine; 2. Engine将requests发送给Scheduler; 3. Engine从Scheduler那获取requests,交给Download下载; 4. 在交给Dowmload过程中会经过Downloader Middlewares(经过process_request函数); 5. Dowmloader下载页面后生成一个response,这个response会传给Engine,这个过程中又经过了Downloader Middlerwares(经过process_request函数),在传送中出错的话经过process_exception函数; 6. Engine将从Downloader那传送过来的response发送给Spiders处理,这个过程经过Spiders Middlerwares(经过process_spider_input函数); 7. Spiders处理这个response,返回Requests或者Item两个类型,传给Engine,这个过程又经过Spiders Middlewares(经过porcess_spider_output函数); 8. Engine接收返回的信息,如果使Item,将它传给Items Pipeline中;如果是Requests,将它传给Scheduler,继续爬虫; 9. 重复第三步,直至没有任何需要爬取的数据 问题 Q3:大数据的文件读取?可用的回答 : 1. 利用生成器generator 2. 迭代器进行迭代遍历:for line in file 问题 Q4:cookie 和session 的区别?可用的回答 : 1、cookie数据存放在客户的浏览器上,session数据放在服务器上。 2、cookie不是很安全,别人可以分析存放在本地的COOKIE并进行COOKIE欺骗考虑到安全应当使用session。 3、session会在一定时间内保存在服务器上。当访问增多,会比较占用服务器的性能考虑到减轻服务器性能方面,应当使用COOKIE。 4、单个cookie保存的数据不能超过4K,很多浏览器都限制一个站点最多保存20个cookie。 5、建议: 将登陆信息等重要信息存放为SESSION 其他信息如果需要保留,可以放在COOKIE中 问题 Q5:什么是PEP 8?可用的回答 :PEP 8是一个编码约定,关于如何编写Python代码更具可读性。问题 Q6:描述数组、链表、队列、堆栈的区别?可用的回答 : 数组与链表是数据存储方式的概念,数组在连续的空间中存储数据,而链表可以在非连续的空间中存储数据; 队列和堆栈是描述数据存取方式的概念,队列是先进先出,而堆栈是后进先出; 队列和堆栈可以用数组来实现,也可以用链表实现。 问题 Q7:json序列化时,默认遇到中文会转换成unicode,如果想要保留中文怎么办?可用的回答 :json.dumps函数方法中加上参数 ensure_ascii = False问题 Q8:什么是Python?使用Python有什么好处?可用的回答 :Python是一种编程语言,包含对象,模块,线程,异常和自动内存管理。Python的好处在于它简单易用,可移植,可扩展,内置数据结构,并且它是一个开源的。问题 Q9:ngnix的正向代理与反向代理?可用的回答 : 正向代理 是一个位于客户端和原始服务器(origin server)之间的服务器,为了从原始服务器取得内容, 客户端向代理发送一个请求并指定目标(原始服务器),然后代理向原始服务器转交请求并将获得的内容返回给客户端。 客户端必须要进行一些特别的设置才能使用正向代理。 反向代理正好相反,对于客户端而言它就像是原始服务器,并且客户端不需要进行任何特别的设置。 客户端向反向代理的命名空间中的内容发送普通请求,接着反向代理将判断向何处(原始服务器)转交请求, 并将获得的内容返回给客户端,就像这些内容原本就是它自己的一样。 问题 Q10:如何在Python中删除文件?可用的回答 :使用命令os.remove(filename) 删除文件 或 os.unlink(filename) 删除快捷方式算法题面试官常问到的一些算法题目整理如下(大概率会机考):算题题 A1:旋转列表题目描述如下:Given a linked list, rotate the list to the right by k places, where k is non-negative.Example 1:Input: 1-2-3-4-5-NULL, k = 2Output: 4-5-1-2-3-NULLExplanation:rotate 1 steps to the right: 5-1-2-3-4-NULLrotate 2 steps to the right: 4-5-1-2-3-NULLExample 2:Input: 0-1-2-NULL, k = 4Output: 2-0-1-NULLExplanation:rotate 1 steps to the right: 2-0-1-NULLrotate 2 steps to the right: 1-2-0-NULLrotate 3 steps to the right: 0-1-2-NULLrotate 4 steps to the right: 2-0-1-NULL旋转链表。 k 非负。k 超过链表的最大长度也可。思路:过一遍链表长度,k % length 取个模,防止 k 超级大。之后 slow fast 两个,fast 先走 k 个,然后 slow 与 fast 同时走,走到最后 slow.next 即为从后到前 k 个的起点。剩下的就是把原来的尾置换到前。下面这个可以优化下,不过就测试来说已经可以了。beat 100%24ms 36ms测试地址:https:/ ListNode(object):# def _init_(self, x):# self.val = x# s
