ucenter应用开发笔记之通信篇
2009 十一月 28
前面做了个I feel lucky ,Joya说到验证问题,说只允许wpg成员加入此活动, 我当时由于时间仓促,就只简单地加上个UID填写再加上后台人工审核认证,
现在觉得其实可以有更好的验证办法。
由于WPG会员都有论坛ID,所以可以用UCenter来验证添加链接的人是不是WPG成员。此处不討論这个如何实现,只说一下想法。
下面是简单地做一下通信测试。
应用路径: /var/www/test/mywebsite
2,部署相关文件
应用路径: /var/www/test/mywebsite

将discuz目录下的uc_client目录复制到应用目录下。
再在应用目录下新建一名为api的目录,其下建新一名为uc.php的文件:

另外应用下的include目录下还有一个mysql数据库类,可以简单地使用discuz的,这里不再帖出了。
若出现UCenter应用“正在连接…” ,一般是由于数据库配置不正确导致的。
应用通讯失败的排查方法

![Discuz!7.0实现PHP代码高亮[原创]](http://static.ihacklog.com/wp-files/2009/04/editor-21x150.gif)








uc的那个example很不错
借鉴下 会有很大的帮助
恩,这个想法不错
