  继上篇刷票风云的随笔之后,我还是决定用每个学生登录教务处的密码尝试一下,虽然这个我在开学的时候做微信开发的时候弄过。

  首先要做的是登录学校教务处网站,然后打开

  1. <span 1<="" span=""> <span <="" span=""><span 第一步:提交数据,生成cookie,将cookie保存在临时目录下="" <="" span=""><span 2<="" span=""> <span 在指定目录中建立一个具有唯一文件名的文件。如果该目录不存在,tempnam()="" 会在系统临时目录中生成一个文件,并返回其文件名<="" span="">
  2. <span 3<="" span=""> <span $cookie_file<="" span="">=<span tempnam<="" span="">('./temp','cookie'<span );="" <="" span=""><span 4<="" span=""> <span $ch<="" span="">=<span curl_init();="" <="" span=""><span 5<="" span=""> <span $login_url<="" span="">="网址"<span ;="" <="" span=""><span 6<="" span=""> <span $curlpost<="" span="">="uname=账号&upwd=密码&usertypex=%B9%DC%C0%ED%D4%B1"<span ;="" <="" span=""><span 7<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_URL,<span $login_url<="" span=""><span );="" <="" span=""><span 8<="" span=""> <span <="" span=""><span 启用时会将头文件的信息作为数据流<="" pre="">输出</span>
  3. <span 9<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible;MS IE 9.0; Windows NT 6.1; WOW 64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.0.30729; BRI/2; MASM; .NET4.0C; .NET4.0E; InfoPath.3; Media Center PC 6.0; SE 2.X MeTaSr 1.0)'<span );="" <="" span=""><span 10<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_HEADER,<span true<="" span=""><span );="" <="" span=""><span 11<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_MAXREDIRS,1<span );="" <="" span=""><span 12<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_RETURNTRANSFER,1<span );="" <="" span=""><span 13<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_FOLLOWLOCATION,1<span );="" <="" span=""><span 14<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_POST,1<span );="" <="" span=""><span 15<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_POSTFIELDS,<span $curlpost<="" span=""><span );="" <="" span=""><span 16<="" span=""> <span <="" span=""><span 设置连接结束后保存cookie信息的文件<="" span="">
  4. <span 17<="" span=""> curl_setopt(<span $ch<="" span="">,CURLOPT_COOKIEJAR,<span $cookie_file<="" span=""><span );="" <="" span=""><span 18<="" span=""> <span $content_login<="" span="">=curl_exec(<span $ch<="" span=""><span );="" <="" span=""><span 19<="" span=""> <span <="" span=""><span print_r($content_login);<="" span="">
  5. <span 20<="" span=""> <span var_dump<="" span="">(<span $cookie_file<="" span=""><span );="" <="" span=""><span 21<="" span=""> curl_close(<span $ch<="" span="">);</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span>

  测试什么都没有显示,因为:

  1. <span $content_login<="" span="">=curl_exec(<span $ch<="" span=""><span );="" <="" span=""><span <="" span=""><span print_r($content_login);<="" span=""></span></span></span></span></span>

  后面会解释,继续:

  1. <span 1<="" span=""> <span $ch2<="" span="">=<span curl_init();="" <="" span=""><span 2<="" span=""> <span $login_url2<="" span="">=网址2"<span ;="" <="" span=""><span 3<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible;MS IE 9.0; Windows NT 6.1; WOW 64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.0.30729; BRI/2; MASM; .NET4.0C; .NET4.0E; InfoPath.3; Media Center PC 6.0; SE 2.X MeTaSr 1.0)'<span );="" <="" span=""><span 4<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_HEADER,0<span );="" <="" span=""><span 5<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_URL,<span $login_url2<="" span=""><span );="" <="" span=""><span 6<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_RETURNTRANSFER,1<span );="" <="" span=""><span 7<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_CONNECTTIMEOUT,120<span );="" <="" span=""><span 8<="" span="">
  2. <span 9<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_AUTOREFERER,1<span );="" <="" span=""><span 10<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_POST,1<span );="" <="" span=""><span 11<="" span="">
  3. <span 12<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_POSTFIELDS,<span $curlpost<="" span=""><span );="" <="" span=""><span 13<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_REFERER,"来源"<span );="" <="" span=""><span 14<="" span=""> <span <="" span=""><span 设置连接结束后保存cookie信息的文件<="" span="">
  4. <span 15<="" span=""> curl_setopt(<span $ch2<="" span="">,CURLOPT_COOKIEFILE,<span $cookie_file<="" span=""><span );="" <="" span=""><span 16<="" span=""> <span $content_login<="" span="">=curl_exec(<span $ch2<="" span=""><span );="" <="" span=""><span 17<="" span=""> <span <="" span=""><span $content_login="1" ;<="" span="">
  5. <span 18<="" span=""> <span print_r<="" span="">(<span $content_login<="" span=""><span );="" <="" span=""><span 19<="" span=""> <span <="" span=""><span curl_exec($ch);<="" span="">
  6. <span 20<="" span=""> curl_close(<span $ch2<="" span="">);</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span>

  在这里,用到的是同一个cookie,这样服务器就可以直接识别了。

  1. <span $content_login<="" span="">=curl_exec(<span $ch2<="" span="">);</span></span>

  这是获取到网页上的内容。

  1. <span print_r<="" span="">(<span $content_login<="" span="">);</span></span>

  这是将获取到的内容打印出来,如果你细心,你可以发现前面有:

  1. <span $content_login<="" span="">='1';</span>

  这么一句话被我注释掉了,这是我检测是否能修改数据用的,当初在获取课表的时候就不能修改获得的数据,也不知道是为何,但是在这里可以。

  如果账号密码错了,就会按网站那样弹出个对话框显示账号密码错误,这样,只要再数据表里面再添加一项student_id便可以了,一个账号只能用一次。

  

  真心希望这次能真正的制止住刷票,我已经心疲力尽了。

  也谢谢网友们,蘑菇街的验证码真心好,我也弄出来了,明天与大家分享,但是刷票器有个功能是手工输入验证码,这又没辙了,所以放弃验证码了。

  我要被那些人骂死了。
