开发公司webSocket(wss)出现连接失败的问题解决方法

前言

开发公司前段时间用Letsencrypt开发公司提供一个称为certbot的工具,生成了HTTPS证书
升级https后,原先的websocket开发公司项目不能有效运行了。。。。

相关技术:linux(centos7.9)//websocket
1.这是升级https后的nginx配置

server {        server_name 你的域名;        location / {                root /www/client/WebSocket-master/src;                index client1.html;        }        location /chat/ {                root /www/client/WebSocket-master/src;                index client2.html;        }    listen 443 ssl; # managed by Certbot    ssl_certificate 改为自己申请得到的 crt 文件路径; # managed by Certbot    ssl_certificate_key 改为自己申请得到的 key 文件路径; # managed by Certbot    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot}server {    if ($host = 你的域名) {        return 301 https://$host$request_uri;    } # managed by Certbot        listen 80;        server_name 你的域名;    return 404; # managed by Certbot}

2.这是websocket服务升级https之前,使用ws连接发生的错误

3.这是将连接方式改为wss后的报错

ws = new WebSocket('wss://ip:端口');

4.需要更改nginx配置和websocket连接方式

ws = new WebSocket('wss://域名');

server {        server_name 你的域名;        location / {                root /www/client/WebSocket-master/src;                index client1.html;                proxy_set_header  Host $host;                proxy_set_header  X-Real-IP  $remote_addr;                proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;                proxy_set_header  X-Forwarded-Proto   $scheme;                proxy_pass        你需要代理的地址;                # 关键配置 start                proxy_http_version 1.1;                proxy_set_header Upgrade $http_upgrade;                proxy_set_header Connection "upgrade";                # 关键配置 end        }        location /chat/ {                root /www/client/WebSocket-master/src;                index client2.html;                proxy_set_header  Host $host;                proxy_set_header  X-Real-IP  $remote_addr;                proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;                proxy_set_header  X-Forwarded-Proto   $scheme;                proxy_pass 你需要代理的地址;                # 关键配置 start                proxy_http_version 1.1;                proxy_set_header Upgrade $http_upgrade;                proxy_set_header Connection "upgrade";                # 关键配置 end        }    listen 443 ssl; # managed by Certbot    ssl_certificate 改为自己申请得到的 crt 文件路径; # managed by Certbot    ssl_certificate_key 改为自己申请得到的 key 文件路径; # managed by Certbot    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot}server {    if ($host = 你的域名) {        return 301 https://$host$request_uri;    } # managed by Certbot        listen 80;        server_name 你的域名;    return 404; # managed by Certbot}
