由于最近QQ垃圾信息群发严重,官方选择将WebQQ部分功能实现细节方面做了点手脚,其中获取好友的POST值多了一个hash参数,这个hash是在js里加密完成的,以下是js源码:

1. <script type="text/javascript">
2. function getHash(b, i) {
3.     for (var a = i + "password error",
4.     s = "", 
5.     j = [];;) if (s.length <= a.length) {                                                                                                       
6.         if (s += b, s.length == a.length) break
7.     } else {
8.         s = s.slice(0, a.length);
9.         break
10.     }   
11.     for (var d = 0; d < s.length; d++) j[d] = s.charCodeAt(d) ^ a.charCodeAt(d);
12.     a = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F"];
13.     s = ""; 
14.     for (d = 0; d < j.length; d++) s += a[j[d] >> 4 & 15],
15.     s += a[j[d] & 15];
16.     return s;
17. }
18. </script>

转成PHP版本处理,源码如下:

1. <?php
2. /**
3. * 获取好友时的POST参数Hash算法
4. *
5. * public
6. * @param string $qq qq号
7. * @param string $ptwebqq cookies中的ptwebqq
8. * @return string
9. */
10. function get_hash($qq, $ptwebqq)
11. {
12. for ($a = $ptwebqq . "password error", $s = "", $j = array();;)
13. {
14.   if (strlen($s) <= strlen($a))
15.   {
16.    $s .= $qq;
17.    if ($s == strlen($a)) break;
18.   }
19.   else
20.   {
21.    $s = substr($s, 0, strlen($a));
22.    break;
23.   }
24. }
26. for ($d = 0; $d < strlen($s); $d++)
27. {
28.   $j[$d] = uniord(substr($s,$d)) ^ uniord(substr($a,$d));
29. }
31. $a = array("0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F");
32. $s = "";
33. for ($d = 0; $d < count($j); $d++)
34. {
35.   $s .= $a[$j[$d] >> 4 & 15];
36.   $s .= $a[$j[$d] & 15];
37. }
39. return $s;
40. }
42. /**
43. * 模拟 JavaScript charCodeAt函数
44. *
45. * protected
46. * @param string $str
47. * @return int
48. */
49. function uniord($str)
50. {
51. list(, $ord) = unpack('N', mb_convert_encoding($str, 'UCS-4BE', 'UTF-8'));
53. return  
55. $ord;
56. }
57. /* End of file commons.php */
