简述

生活当中免不了要下载百度文库，但是百度很恶心的是要下载券，收费呀啥的（这次的这个不能下载收费文档哦），所以我就在微信的搜索功能（非常强大）上搜怎么样免费下载百度文库，加了一些群，其中一个群就是有一个有专门的机器人，只要你往群里发链接，机器人自动回复你下载链接

首先我在csdn上查阅相关资料群机器人的文章，明白Python关于群机器人有两大类，QQ群用qqbot库（基于smartqq），微信群用itchat库（基于微信网页版）。但是腾讯已经把smartQQ关了（也就 是不能通 过qqbot来制作QQ群机器人），只能建一个微信群机器人

制作思路：

1、通过itchat登录微信，实时监听所要建的群消息，假如有人发文库链接，将链接提取出来（比较简单）

2、将所提取到的文库连接保存，然后请求下载网站，网站返回下载链接（这个还得要自己去抓包，去慢慢分析，我也是花了一整天才把他整个下载流程弄懂，很麻烦，今天我们重点讲这个，你们可以拿其他网站试试，亲测这个链接很长，我用到了百度的短连接，为了本帖不冗长，省去不讲）

3、将网站返回的链接发送给相应的群，并@相应的人（比较简单）

这个网站链接是：http://139.224.236.108/1.html（免费给他打了一波广告把，这个网站是收费的，下载的文档也是源文档，买账号也就几块钱，但是每个账号每天会限制下载次数，但是你可以多买几个账号，当一个被限制了之后，遍历其他账号，这样就OK了，其实下载文档这个不是经常下，但是有需求的时候没有下载券就麻烦了，为了兄弟们更好的复现，我把我买的账号分享给大家）

在百度文库上随便获取一个要下载券的文档链接，

点击下载之后又是一波抓包，发送了请求post和nocode

跳转到如下界面：

再点击这个下载，又发送了一个请求具体见下面的down()，就不再过多讲了直接上代码：

# 将传入的文档链接进行转化
downloadurl = firsturl.replace("/", "%2F").replace(":", "%3A")
# head1查询文档ID的数据头

# 查询得到结果，截取id的那一段并返回

downurl = response["dlink"].replace("\", '')
print(downurl)#点击这个URL，会自动下载文件哦
return downurl
query()
down()
</pre>

上面可以实现一个独立的下载，但是如果我们要和微信联系起来，制作微信机器人，那么，我们可以把上面的query(),down(),弄成一个函数，传入一个链接，经过这个函数处理，返回下载地址，到时候直接调用这个函数即可

接下来就是登陆微信，监控对应的群，放在服务器上，你就可以打造出24小时下载的机器人了。

实现代码：

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">@itchat.msg_register([itchat.content.TEXT], isGroupChat=True) # 注册一个群消息的处理
def print_content(msg):
if msg.User["NickName"] == qun:# 这里可以在后面加更多的or msg.User["NickName"]=='你希望自动回复群的名字
if str(msg['Text'][0:5])=="https":#检测所发的消息是不是链接，是通过前5个
huifubdwk= GET_SHORTURL(str(msg['Text']))#这个GET_SHORTURL是我上面所说的那个函数，我自己定义的
print(msg.User['NickName'] + ":" + msg['Text'] ) # 打印哪个群给你发了什么消息
print("%s+\n"%huifubdwk) # 打印机器人回复的消息
itchat.send(u'@%s\u2005 %s' % (msg['ActualNickName'],huifubdwk), msg['FromUserName'])
else:# 不是链接直接忽略
print(msg['Text'])
else:#不是相应群直接忽略
pass
</pre>

好了，今天到这就结束了

只要把文库链接甩进去，机器人就会自动返回下载地址，爽歪歪。
