Resolves the problem that discuz 3.4 forced upload avatars cannot be used (always prompts you to upload avatars)

本次问题是：开启了强制头像上传，即便上传了头像，依旧说没有权限发表，请上传头像。

The main reason is the communication with uc_derver, which shows successful communication, but this may not be accurate (the reasons are very complex), and the website has enabled HTTPS, so the reason is even more complicated.

问题就出在了头像获取上，在uc_client/client.php中，找到

$path = $matches['path'] ? $matches['path'].($matches['query'] ? '?'.$matches['query'] : ''):'/';

下面增加：

$matches['port'] = !empty($matches['port'])&&$scheme=='https' ? $matches['port'] : 443;

然后找到：

if(!$fp = @fsocketopen(($ip ? $ip : $host), $port, $errno, $errstr, $timeout)) {

在修改为：

if($port=='443'){$temp = 'ssl://';}else{$temp = 'http://';}if(!$fp = @fsocketopen($temp.($ip ? $ip : $host), $port, $errno, $errstr, $timeout)) {

至此应该修复了该问题了，如果还没修复，尝试以下方法：

在function uc_check_avatar中找到

$res = uc_fopen2($url, 500000, ”, ”, TRUE, UC_IP, 20);

修改为：

$res = trim(uc_fopen2(UC_API."/avatar.php?uid=$uid&check_file_exists=1"));

原本的call很不稳定，有时候返回不出1，新的这个直接打开url返回数值。
