移动端突然访问超级慢，不知道是什么问题！经过排查是因为curl_exec($curl)获取ticket要几十秒时间，curl_getinfo($curl)打印了一下信息如下：

array(26) {

  ["url"] => string(232) "https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=43_mN9vHz-KwpR8WG************************************V8U3zfNMuCUz4-87KhRPhpH7IRxl***********************D0pEllsjhbCU1nw-R9acjaU-VSEDjAFAVHG&type=jsapi"

  ["content_type"] => string(32) "application/json; encoding=utf-8"

  ["http_code"] => int(200)

  ["header_size"] => int(149)

  ["request_size"] => int(262)

  ["filetime"] => int(-1)

  ["ssl_verify_result"] => int(0)

  ["redirect_count"] => int(0)

  ["total_time"] => float(12.62799)

  ["namelookup_time"] => float(0.000254)

  ["connect_time"] => float(0.331384)

  ["pretransfer_time"] => float(12.14724)

  ["size_upload"] => float(0)

  ["size_download"] => float(143)

  ["speed_download"] => float(11)

  ["speed_upload"] => float(0)

  ["download_content_length"] => float(143)

  ["upload_content_length"] => float(-1)

  ["starttransfer_time"] => float(12.627968)

  ["redirect_time"] => float(0)

  ["redirect_url"] => string(0) ""

  ["primary_ip"] => string(14) "203.205.239.94"

  ["certinfo"] => array(0) {

  }

  ["primary_port"] => int(443)

  ["local_ip"] => string(13) "172.26.61.196"

  ["local_port"] => int(33600)

}

求教了
