篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了如何复制起点网的小说？相关的知识，希望对你有一定的参考价值。
我看无收费小说时，文件-另存为-把扩展名改成txt就可以了，不知道收费小说可不可以？
有什么方法？那些盗版网站都是打字，错别字一大堆。
javascriptdocument.oncontextmenu = \'\';document.onmousedown = \'\';document.ondragstart = \'\'; document.onselectstart = \'\';document.onselect = \'\'; document.oncopy = \'\';document.onbeforecopy = \'\'; document.onmousemove = \'\'; void 0
起点中文网是国内最大文学阅读与写作平台之一，是目前国内领先的原创文学门户网站。
创立于2002年5月的起点中文网前身为起点原创文学协会（Chinese Magic Fantasy Union），长期致力于原创文学作者的挖掘与培养工作， 并以推动中国文学原创事业为发展宗旨，在2003年10月以此为契机开创了在线收费阅读即电子出版的新模式。 参考技术A 起点小说网虽然进行了很严格的防复制技术，但也只是小儿科，只能防止你们这些菜鸟，一样可以复制。除非是他们收费的内容看不到，只要能打开的内容都可以随便复制。只是需要一点技巧。想了解请给我发私信活在我空间留言。我告诉你。 参考技术B 不可以，我在学网页制作，问过老师，起点的网站设有保户，连网页上的图片都不能保存，更不要提收费的内容了。和一楼一样，建议你去贴吧或者其他网站看看本回答被提问者采纳 参考技术C 起点不能复制
实在不行可在那本小说贴吧去找
用crawl spider爬取起点网小说信息
起点作为主流的小说网站，在防止数据采集反面还是做了准备的，其对主要的数字采用了自定义的编码映射取值，想直接通过页面来实现数据的获取，是无法实现的。
单独获取数字还是可以实现的，通过requests发送请求，用正则去匹配字符元素，并再次匹配其映射关系的url,获取到的数据通过font包工具解析成字典格式，再做编码匹配，起点返回的编码匹配英文数字，英文数字匹配阿拉伯数字，最后拼接，得到实际的数字字符串，但这样多次发送请求，爬取效率会大大降低。本次集中爬取舍弃了爬取数字，选择了较容易获取的评分数字。评分值默认为0 ，是从后台推送的js数据里取值更新的。
实现的主要代码：
items部分：

settings进行简单配置，就可以运行程序了。
为了方便调试程序，可以在项目外编写一个main.py入口文件，和命令行执行 scrapy crawl read 效果是一样的。
main代码如下：
from scrapy import cmdline
cmdline.execute(‘scrapy crawl read‘.split())
