我的第一个爬虫
废话少说,先上图:在网上下载gho系统时,找到了一个叫技术员联盟的网站(http://www.jsgho.net),有个图片的标签,点开一看,哇,全是美女(穿了衣服的),刚好学到爬虫,练练手吧。观察了一下,发现所有的图片都在www.jsgho.net/image/下面,查看了一上网页的源代码,图片在<li></li>标签的<img src里面,不过有个小问题就是网址不全,取下来后还要加上网站的地址,开工。(附全部网址),新人,代码写的很烂,请大神们多多指点,谢谢。

请问这个错误是哪错了 czfasaoyou 发表于 2019-12-31 13:34

没有 bs4 模块
需要安装,在命令行下运行:pip install bs4 谢谢 UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 11: illegal multibyte sequence,这个又是哪里错了?谢谢 czfasaoyou 发表于 2019-12-31 16:30

编码错误,把完整的异常提示发来看看。 Traceback (most recent call last):

把这句with open("C://Users//Administrator//Desktop//sitemap.txt") as f:
改成with open("C://Users//Administarator//Desktop//sitemap.txt", encoding='utf-8') as f:看看
还有你要看看你下载的sitemap.txt文件的路径,把C://Users//Administarator//Desktop替换成你的sitemap.txt的路径。 谢谢,我试试 修改,运行的时候提出错误syntaxerrorinvalid character in identifier ,光标停在encoding czfasaoyou 发表于 2020-1-4 14:16
