通过SSL的Websocket

我正在使用Ratchet在PHP中实现基于Websockets的应用程序，并且如果我处于http模式（ws），则可以成功完成此操作

如果切换到https，则无法执行相同操作。它显示连接超时，我什至在telnet中尝试过，但服务器端未看到任何响应（显示客户端已连接）

1）我使用wss而不是ws

var conn = new WebSocket('wss://www.mysite.com:8080/wss2');

我根据这个答案设置了wss2：php ratchet websocket SSL connect？ （我已将Proxypass行添加到我的apache配置文件中）

2）我加载了所有必要的Apache模块

[0] => core
[1] => mod_so
[2] => mod_watchdog
[3] => http_core
[4] => mod_log_config
[5] => mod_logio
[6] => mod_version
[7] => mod_unixd
[8] => mod_access_compat
[9] => mod_alias
[10] => mod_auth_basic
[11] => mod_authn_core
[12] => mod_authn_file
[13] => mod_authz_core
[14] => mod_authz_host
[15] => mod_authz_user
[16] => mod_autoindex
[17] => mod_deflate
[18] => mod_dir
[19] => mod_env
[20] => mod_filter
[21] => mod_headers
[22] => mod_mime
[23] => prefork
[24] => mod_negotiation
[25] => mod_php5
[26] => mod_proxy
[27] => mod_proxy_ajp
[28] => mod_proxy_balancer
[29] => mod_proxy_connect
[30] => mod_proxy_html
[31] => mod_proxy_http
[32] => mod_proxy_wstunnel
[33] => mod_rewrite
[34] => mod_setenvif
[35] => mod_slotmem_shm
[36] => mod_socache_shmcb
[37] => mod_ssl
[38] => mod_status

3）我确实重启了Apache服务器

4）如果将其添加到配置中，服务器将无法工作：

Listen 443
NameVirtualHost *:443

SSLEngine On

# Set the path to SSL certificate
# Usage: SSLCertificateFile /path/to/cert.pem
SSLCertificateFile /etc/apache2/ssl/file.pem


# Servers to proxy the connection, or;
# List of application servers:
# Usage:
# ProxyPass / http://[IP Addr.]:[port]/
# ProxyPassReverse / http://[IP Addr.]:[port]/
# Example: 
ProxyPass / http://0.0.0.0:8080/
ProxyPassReverse / http://0.0.0.0:8080/

# Or, balance the load:
# ProxyPass / balancer://balancer_cluster_name

如果添加以下内容，我的日志中就会出现错误：

我确实指定了来自letencrypt的证书文件（cert.pem）的来源

注意：HTTPS在我的服务器中有效

我现在应该怎么做？我只希望websockets通过HTTPS工作。

我正在使用Ubuntu 14.10，已安装Apache 2.4.1

我当前的配置文件：

    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com


    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    ProxyPass /wss2/ ws://www.mysite.com:8080/  #Removed this line now
    ProxyPass /wss2/ wss://www.mysite.com:8080/

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
 RewriteEngine on
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [L,QSA,R=permanent]


# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

提前致谢。

我自己经过长时间的挣扎才弄清楚了。

在文件“ /etc/apache2/mods-enabled/proxy_wstunnel.load”中添加此行（带有您自己的名称和端口）。8000是运行我的Websocket服务器的端口。

ProxyPass "/websocket"  "ws://localhost:8000/"

重新启动Apache服务器。

然后在连接期间使用如下网址：

socket = new WebSocket("wss://www.xyz.com/websocket"); 

xyz.com指向您的本地主机的位置

而已。如果要启用各个模块，请使用apache的a2enmod
