Discuz! X2.5 与 UCenter 通信失败的解决方法

1、解决方法总结如下：1、检查站点配置文件中的 UC_APPID 与 UCenter 中的应用ID是否一致以Discuz! X2.5为例，配置文件的目录为：./config/config_ucenter.php 找到如下图所示的位置这里的值必须与 UCenter 后台中应用ID的值保持一致，如下图所示。

2、应用的主 URL 地址即站点地址必须与 UCenter 后台的应用地址相同

3、配置文件中的通信密钥必须与 UCenter 后台的通信密钥保持一致配置文件的通信密钥可以在./config/config_ucenter.php 中看到。这里的密钥必须和 UCenter 后台的保持一致。

4、UCenter IP 地址要与服务器的 ip 地址相同可以在配置文件中修改 IP 地址，如图同理，UCenter 后台的应用 IP 地址也要和配置文件中的一致。应用管理中，编辑站点应用即可看到如下图所示：

5、检查配置文件中的表前缀是否填写正确位置在./config/config_ucenter.php 中

6、fsockopen函数被禁用检查 php 环境，是否禁用了 fsockopen 函数，可以通过 php.ini 来查看该函数的情况，在这个文件中查找allow_url_fopen将其改为allow_url_fopen = On

7、应用域名301重定向的情况301重定向可以用fsockopen函数进行测试：用下面的代码<患修校楷?php$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$fp = fsockopen("[url=http://www.example.com]www.example.com[/url]", 80, $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$errno, $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$errstr, 30);if (!$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$fp) { echo "$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$errstr ($$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$errno)\n";} else { $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$out = "GET / HTTP/1.1\r\n"; $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$out .= "Host: [url=http://www.example.com\r\n]www.example.com\r\n[/url]"; $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$out .= "Connection: Close\r\n\r\n"; fwrite($$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$fp, $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$out); while (!feof($$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$fp)) { echo fgets($$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$fp, 128); } fclose($$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$fp);}?>将对应的域名更改为 UCenter 应用中的域名，然后访问此测试脚本,返回的内容有 301 permanently 内容，通信也会失败。您只要取消重定向即可，一般是 301 跳转规则有问题。
