您好，测试发现，在下载中会出现不少的无效图片，显示请耐心等候或者刷新重试。

如果使用代理上网如何配置？谢谢UP

麻烦问下我是用的更新到最新版本的，下载时提示登陆错误，程序异常退出：
C:\Users\Administrator\Desktop\wqxuetang_downloader-master>python main.py 3199490
2020-02-06 14:18:52,394 [ERROR] 登录错误，程序异常退出。
请问该如何解决？

我是隔壁wqDownloader的作者，前两天没发现这个仓库就用自己的方法抓了几本书下来。现在可能服务器扛不住了一直加载不出来，上GitHub再搜就发现了这个仓库。

用知识战疫

这是文泉学堂近期免费图书的初衷，但是现在服务器的状态似乎并不乐观，所以如果有人需要的话，我愿意将自己之前下的分享出来。但与文泉学堂一样，疫情结束，我就取消分享。

请问源码在哪里啊？没有找到😓

清华的资源不能为全体国人所共享，平时只能为一小部分人所享，其实是国家教育资源不平等的体现，是一个很扯很丢脸的事。
人类之所以技术发展到现在，就是因为知识传播与技术共享，让越来越多的人掌握科技，人类的整体水平才不断发展。
一部分人想靠技术发财，且不让别人致富，世上就出现了各种保护技术私有的手段，充分说明人类有多自私。平民百姓需要更多的钱去获取技术产品及获取知识。
当年互联网先驱们，发明互联网就是为了共享，分享啊。为什么要无私共享分享？就是为了不让自私的人或资本垄断技术，从而更好地促进人类的福祉啊。
专利和技术保护手段实际上是保护了资本的利益，让世界的财富分配日益不平衡，贫富差距导致各种发展问题，产生各种丑恶。我刚才看到一个说写什么人血馒头的那个家伙的脑子是不是坏掉了？
不管如何，清华的资源能通过这个工具被越多的人所看到，对国家的发展，对科技的发展，都是一个极好的事情。无私分享这个工具的人，没有私心。利国利民，侠之大者！

• 在wqxtDownloader init()增加一个方法将链接转换为bid
• 在wqxtDownloader init()增加一个方法检测bid是否正确
• 在wqxtDownloader initread()返回数据接口时，检测是否返回{"data":[],"errcode":8003,"errmsg":"很抱歉，您访问的图书不存在"}

输出代码中的data信息,显示data: {"data":[],"errcode":3001,"errmsg":"请先登录"}

就是前几十页好好的，后面就变成10k的左右的图片了，怎么解决呢？

能否增加个出现 HTTP Error 502 的时候，自动重启的功能？

碎碎念，都是穷人，免费下了基本好书，何必上纲上线，心态下楼主~~
PS：能指导下载python中打入patch补丁？？完全找不大资料呀，commit ad0c714 直接输入直接报错，感谢

已按照步骤，登录并修改PHPSESSID值，仍出现登录错误，如下：

下载到一定页数后，就下载不动了，需要重新启动程序才能下载。能否建立一个检测机制，让程序能自动重启下载？

请问是因为什么原因？

服了和我们对线的老哥了

因为本身下载需要模拟人在阅读，耗时很长，所以最好能支持多个待下载bid，感谢大佬。

构造函数

def __init__( self, bid ):
	# 储存输入列表
	self.bid = bid;
	self.jwt_key = self.getJwtKey();
	bookInfo = self.initread();
	
	self.name = bookInfo['name'];
	
	self.page = int(bookInfo['pages']);

	folder = self.getFolder();
	self.createFolder( folder );
	self.folder = folder;
	self.catatree = self.getCatatree();
	self.invalidpic = self.getInvalidPicInfo();

这一块没改动，咋还报错了，咋修复。好像是数据类型出错了，。

运行程序后报错，请问有没有方法可以解决？感谢！下载完全只是自己阅读，完全不会用于商业用途。

知识是学习进步的唯一方法，看书而且看有用的书才会对学习有帮助，网上其他电子书资源质量也是参差不齐，很多作者写点书全是水没有干货，而且基础科学的书籍也少得可怜，所以就是想白嫖一下清华出版社的书籍。不过白嫖失败，没有配置好，刚上车就熄火了。
有人觉得是吃人血馒头？
请问知网和其他**的学术网站下载都要收钱，钱又不会分给写论文的机构和个人，他们是不是吃人血馒头，本来不懂才看才学习的还要找学生要钱，更何况学生时代本来就没多少钱，别说什么校园网免费，只能说你不食肉糜，只知道你当下的情况。
难道穷人就活该享受不了公平获得知识的机会？
你觉得会有人拿去卖，从而导致正版受到伤害，我很不明白有人想贩卖盗版去赚钱难道只会这一种方式获取？想必不会吧，比如学校的围墙建的再高也会有人铤而走险，你能把他犯罪的心控制住吗？

要不要加一个获取到这种错误信息就停两分钟，然后两分钟后继续访问

我可能觉得你想秀一秀自己的技术，或者是为了“造福”不想花钱的人。但是你明知这是窃取别人的知识产权，破坏计算机系统，还发布这样的程序，实在是有悖于技术伦理。在疫情下，你这样说是吃人血馒头也不为过；即使不是在疫情下，这也属于无良的技术。没有利益相关，我只是觉得，如果一个技术人没有技术伦理，无异于高知识的犯罪分子，更让人愤恨！

3207901，291张图，我重复下载了两次，每张图都看过都没有问题，但是转换PDF时报Invalid argument，我不清楚里面哪张图有问题导致的，能否提供些解决或者发现问题的思路？下了十多本书，就这个遇到问题了

前面下载了一些图片文件还正常，但后面就无法下载了，先是表现为得到的图片文件大小只有5字节。中断程序运行后删除这些无效图片文件，再重新运行后就提示“获取到了失败的图片”，是否是被封了？该怎么解决？谢谢！
