解决SOAP客户端在请求https时设置超时时间无效导致进程卡死问题
目前有一个进程服务脚本是不断查询渠道的接口，但是历史问题是有时订单量大的时候进程会卡死，这次遇到了进行排查一下：
首先获取该进程ID
ps -aux | grep QueryABC.php
sync360 11115 0.0 0.0 6564 864 ? Ss 14:00 0:00 /bin/sh -c /usr/local/bin/php /xxxx/xxxx/xxxx/xxxx/xxxx/xxxx/xxxx/xxxx/xxxx/QueryABC.php BILL99DF 10-8>> /home
sync360 11124 0.0 0.4 361628 17296 ? S 14:00 0:04 /usr/local/bin/php /xxxx/xxxx/xxxx/xxxx/xxxx/xxxx/xxxx/xxxx/xxxx/QueryABC.php BILL99DF 10-8
sync360 25230 0.0 0.0 63384 872 pts/0 S+ 15:28 0:00 grep QueryABC.php
strace查看该进程正在持续的状态
sudo strace -T -tt -e trace=all -p 11124

lsof查看进程的所使用的文件
lsof -p 11124

可以发现最终是停留在https的链接建立，等待获取数据，查看此处代码
ini_set('default_socket_timeout',30);
scOptions = array('connection_timeout' => 30);clientObj = new SoapClient( wsdl ,scOptions);
当前版本php较老，这里是有个bug的在https链接请求时SOAPClient的超时时间是不生效，最终采取如下方案解决此问题：
复写SOAPClient，在https时候使用curl来完成请求解决问题
<?php
class SoapClientTimeout extends SoapClient
{
private timeout;
public function __setTimeout(timeout)
{
if (!is_int(timeout) && !is_null(timeout))
{
throw new Exception("Invalid timeout value");
}
this->timeout =timeout;
}
public function __doRequest(request,location, action,version, one_way = FALSE)
{
if (!this->timeout)
{
// Call via parent because we require no timeout
response = parent::__doRequest(request, location,action, version,one_way);
}
else
{
// Call via Curl and use the timeout
curl = curl_init(location);
curl_setopt(curl, CURLOPT_VERBOSE, FALSE);
curl_setopt(curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt(curl, CURLOPT_POST, TRUE);
curl_setopt(curl, CURLOPT_POSTFIELDS, request);
curl_setopt(curl, CURLOPT_HEADER, FALSE);
curl_setopt(curl, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
curl_setopt(curl, CURLOPT_TIMEOUT, this->timeout);response = curl_exec(curl);
if (curl_errno(curl))
{
throw new Exception(curl_error(curl));
}
curl_close(curl);
}
// Return?
if (!one_way)
{
return (response);
}
}
}
