三十九、Swoole 基础学习笔记 - Swoole 协程 HTTP/WebSocket 客户端
hi，我是温新，一名PHPer
文章基于 Swoole 5.0.1 版本编写。
学习目标：学习协程 HTTP/WebSocket 服务器
说明：本篇文章结合官方文档编写及参考网络资料编写，虽非全部原创，但也是结合了自己的理解，若转载请附带本文 URL，编写不易，持续编写更不易，谢谢！
协程版 HTTP 客户端的底层用纯 C 编写，不依赖任何第三方扩展库，拥有超高的性能。
- 支持
Http-Chunk、Keep-Alive特性，支持form-data格式； -
HTTP协议版本为HTTP/1.1； - 支持升级为
WebSocket客户端； -
gzip压缩格式支持需要依赖zlib库； - 客户端仅实现核心的功能，实际项目建议使用 Saber。
演示案例

注意：
1、某些情况下请求虽然是成功的，
upgrade返回了true，但服务器并未设置HTTP状态码为101，而是200或403，这说明服务器拒绝了握手请求；2、
WebSocket握手成功后可以使用push方法向服务器端推送消息，也可以调用recv接收消息；3、
upgrade会产生一次协程调度。
push
含义：向 WebSocket 服务器推送消息。
