在nginx环境下搭建基于ssl证书的websocket服务转发,wss

1、证书准备

本地调试，可以安装自签名证书，安装方法参考https本地自签名证书添加到信任证书访问

2、修改配置文件

将上面的配置文件拷贝到conf目录，添加或者修改节点如下

# HTTPS server
    server {
        listen       443 ssl;
        server_name  www.aaa.com;

    ssl on;
        ssl_certificate      www.aaa.com+5.pem;
        ssl_certificate_key  www.aaa.com+5-key.pem;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;

        #charset koi8-r;
        access_log logs/aiPlatform/access_log;
        error_log  logs/aiPlatform/error_log   error;

        location / {
            proxy_pass  http://127.0.0.1:8111;
            proxy_redirect   off;
            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For
                       $proxy_add_x_forwarded_for;
        }

        location /api/asr {
            proxy_pass http://127.0.0.1:81/api/asr;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
        }

        location /api/tts {
            proxy_pass http://127.0.0.1:81/api/tts;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
        }
    } 

以上会将基于ssl证书的websocket请求按照请求地址转发到本地服务的81端口上。

wss://www.aaa.com/api/asr转发到 127.0.0.1:81/api/asr

wss://www.aaa.com/api/tts转发到 127.0.0.1:81/api/tts
