症状：php curl调用https出错
排查方法：在命令行中使用curl调用试试。
原因：服务器所在机房无法验证SSL证书。
解决办法：跳过SSL证书检查。
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
症状：php curl调用curl_exec返回bool(false)，命令行curl调用正常。
排查方法：
var_dump(curl_error($ch));
返回：
string(23) "Empty reply from server"
再排查：
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
返回：
HTTP/1.1 100 Continue
Connection: close
原因：php curl接收到HTTP 100就结束了，应该继续接收HTTP 200
解决方案：
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
PHP and cURL: Disabling 100-continue header
Published June 15th, 2006
I've been using cURL (through PHP) to build a sort of proxy for a project I'm working on. I need to parse the returned headers (to recover the HTTP status), so had included a very simple script to do so. It had worked fine in the past, but for some reason barfed in this case. A closer look at what was being returned revealed that for some reason, Apache was prepending the ‘normal' headers with an extra response header:
HTTP/1.1 100 Continue
HTTP/1.1 200 OK Date: Fri, 09 Jun 2006 15:23:42 GMT
Server: Apache
...A bit of Googling revealed that this was to do with a header that cURL sends by default:
Expect: 100-continue
…which in turns tells Apache to send the extra header. I poked around a fair bit but couldn't quite find a workable solution short of manually removing the header in PHP, which seemed a bit clumsy. Finally, on a hunch I tried this:
curl_setopt( $curl_handle, CURLOPT_HTTPHEADER, array( 'Expect:' ) );
…which basically overrides the original ‘Expect:' header with an empty one.
Hope this helps someone.

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒 经典版》的玩家都可以获得奖励。
