最近小程序上迭代了一个基于websocket的即时聊天功能。打开微信公众平台后台设置socket合法域名时发现使用的是wss协议。什么是wss呢？在 SSL 上运行 WebSocket 协议就是 WSS; 在 SSL 上运行 HTTP 协议就是 HTTPS
WSS 是 Web Socket Secure 的简称, 它是 WebSocket 的加密版本. 我们知道 WebSocket 中的数据是不加密的, 但是不加密的数据很容易被别有用心的人窃取, 因此为了保护数据安全, 人们将 WebSocket 与 SSL 结合, 实现了安全的 WebSocket 通信, 即 WebSocket Secure.
所以说 WSS 是使用 SSL 进行加密了的 WebSocket 通信技术。
先在微信公众号后台和字节跳动开发者平台配置socket 合法域名
1、首先申请域名的https证书，各大云服务商都有提供免费https证书，这里我就不演示如何申请证书了。
2、配置https证书。不想手动配置的可以到这个网站一键生成 Nginx config
server
{
listen 80;
listen 443 ssl http2;
#listen [::]:443 ssl http2;
server_name caiguanrong.com www.caiguanrong.com ;
index index.html index.htm index.php default.html default.htm default.php;
root /web_root;
ssl_certificate /usr/local/nginx/conf/ssl_key/www.caiguanrong.com.pem;
ssl_certificate_key /usr/local/nginx/conf/ssl_key/www.caiguanrong.com.key;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;
ssl_ciphers "TLS13-AES-256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-128-GCM-SHA256:TLS13-AES-128-CCM-8-SHA256:TLS13-AES-128-CCM-SHA256:EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5";#配置加密套件
ssl_session_cache builtin:1000 shared:SSL:10m;
# openssl dhparam -out /usr/local/nginx/conf/ssl/dhparam.pem 2048
ssl_dhparam /usr/local/nginx/conf/ssl/dhparam.pem;
include rewrite/thinkphp.conf;
#error_page 404 /404.html;
include enable-php-pathinfo.conf;
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 12h;
}
location ~ /.well-known {
allow all;
}
location ~ /\.
{
deny all;
}
access_log /home/wwwlogs/caiguanrong.com.log;
}3、配置wss
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
#wss配置代理到ws:127.0.0.1:9503
upstream websocket {
server 127.0.0.1:9503; #ip:port
}
server
{
listen 80;
listen 443 ssl http2;
#listen [::]:443 ssl http2;
server_name caiguanrong.com www.caiguanrong.com ;
index index.html index.htm index.php default.html default.htm default.php;
root /web_root;
ssl_certificate /usr/local/nginx/conf/ssl_key/www.caiguanrong.com.pem;
ssl_certificate_key /usr/local/nginx/conf/ssl_key/www.caiguanrong.com.key;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;
ssl_ciphers "TLS13-AES-256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-128-GCM-SHA256:TLS13-AES-128-CCM-8-SHA256:TLS13-AES-128-CCM-SHA256:EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5";#配置加密套件
ssl_session_cache builtin:1000 shared:SSL:10m;
# openssl dhparam -out /usr/local/nginx/conf/ssl/dhparam.pem 2048
ssl_dhparam /usr/local/nginx/conf/ssl/dhparam.pem;
include rewrite/thinkphp.conf;
#error_page 404 /404.html;
include enable-php-pathinfo.conf;
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 12h;
}
location ~ /.well-known {
allow all;
}
location ~ /\.
{
deny all;
}
#websocket 配置 通过配置端口指向部署websocket的ip
location /socket {
proxy_pass http://websocket;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade; # 升级协议头
proxy_set_header Connection "Upgrade";
proxy_set_header X-real-ip $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
}
access_log /home/wwwlogs/caiguanrong.com.log;
}最后重载nginx 配置。
nginx -t #检测配置是否正确，输出如下就配置正确了
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
nginx -s reload #重新加载配置文件然后可以通过在线websocket 测试是否能正确连接 。
