分析其主要原因是phpsso与ucenter通信成功后，XXX_ucenter_member表中的用户已经同步成功但是在XXX_common_member中并没有此用户，所以只要在xxx_common_member中插入此用户就可以了,所以修改discuz/api/uc.php下的synlogin函数就可以了，修改为

1. functionsynlogin($get,$post){
2. global$_G;
4. if(!API_SYNLOGIN){
5. returnAPI_RETURN_FORBIDDEN;
6. }
8. header('P3P:CP="CURaADMaDEVaPSAoPSDoOURBUSUNIPURINTDEMSTAPRECOMNAVOTCNOIDSPCOR"');
10. $cookietime=31536000;
11. $uid=intval($get['uid']);
12. $query=DB::query("SELECTuid,username,passwordFROM".DB::table('common_member')."WHEREuid='$uid'");
13. if($member=DB::fetch($query))
14. {
15. dsetcookie('auth',authcode("$member[password]\t$member[uid]",'ENCODE'),$cookietime);
16. }else
17. {
18. $username=$get['username'];
19. $query=DB::query("SELECTuid,username,password,emailFROM".DB::table('ucenter_members')."WHEREusername='$username'");
20. $member=DB::fetch($query);
21. $password=$member['password'];
22. $email=$member['email'];
23. $ip=$_SERVER['REMOTE_ADDR'];
24. $time=time();
25. $userdata=array(
26. 'uid'=>$uid,
27. 'username'=>$username,
28. 'password'=>$password,
29. 'email'=>$email,
30. 'adminid'=>0,
31. 'groupid'=>10,
32. 'regdate'=>$time,
33. 'credits'=>0,
34. 'timeoffset'=>9999
35. );
36. DB::insert('common_member',$userdata);
38. $status_data=array(
39. 'uid'=>$uid,
40. 'regip'=>$ip,
41. 'lastip'=>$ip,
42. 'lastvisit'=>$time,
43. 'lastactivity'=>$time,
44. 'lastpost'=>0,
45. 'lastsendmail'=>0
46. );
47. DB::insert('common_member_status',$status_data);
48. DB::insert('common_member_profile',array('uid'=>$uid));
49. DB::insert('common_member_field_forum',array('uid'=>$uid));
50. DB::insert('common_member_field_home',array('uid'=>$uid));
51. DB::insert('common_member_count',array('uid'=>$uid));
52. DB::query('UPDATE'.DB::table('common_setting')."SETsvalue='$username'WHEREskey='lastmember'");
53. $query=DB::query("SELECTuid,username,passwordFROM".DB::table('common_member')."WHEREuid='$uid'");
54. if($member=DB::fetch($query))
55. {
56. dsetcookie('auth',authcode("$member[password]\t$member[uid]",'ENCODE'),$cookietime);
57. }
58. }
59. }

这样在phpcms中注册后去discuz中就可以不用激活就自动登录了
