1.1. Curl swoole HttpServer 慢

• php-fpm 下curl 访问本地 127.0.0.1 swoole HttpServer
• api 公网响应 40ms ,内网响应 1s+
• 通过tcpdump 抓包分析看到发送包耗时 1s +
• tcpdump -i lo -A -n "src host 127.0.0.1 and port {port}"

1.1.1. Expect: 100-continue

.x...x..POST /xxxx/xxxxx HTTP/1.1
...
Expect: 100-continue

1.2. 解决方案

  nginx 代理一下server
  或者 curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
