swoole 配置 ssl 使用

问题描述

在 http 页面请求 websocket ，可以正常请求。但在 https 页面请求 websocket 却报下边这样的错误：

failed: Error in connection establishment: net::ERR_SSL_PROTOCOL_ERROR

现场环境

websocket 服务端使用的 swoole，编译时，也带上了 --enable-openssl，执行 php --ri swoole 时，结果如下：

swoole

Swoole => enabled
Author => Swoole Team <team@swoole.com>

pcre => enabled
zlib => enabled

pthread_barrier => enabled
futex => enabled
async_redis => enabled

Directive => Local Value => Master Value
swoole.enable_coroutine => On => On
swoole.display_errors => On => On
swoole.use_shortname => On => On
swoole.unixsock_buffer_size => 8388608 => 8388608

页面 js请求也换成了 wss，ssl 证书也添加了。请问有小伙伴遇到过这样的问题么。可有解决方法。谢谢。
