我已成功将 Nginx 配置为我的 Web 应用程序的反向代理。它正确地将我的 Angular SPA 发出的请求重定向到用 Asp Core 2.1 编写的 Web API。但是,在我的 Web API 中,我想使用 WebSockets
ws://mydomain.com/ws
建立连接。
这就是我的网站现在的样子
server {
listen 80;
listen 443;
ssl on;
ssl_certificate /etc/***/***.crt;
ssl_certificate_key /etc/***/***.key;
root /home/***/***/***/wwwroot;
# Add index.php to the list if you are using PHP
index index.html;
server_name my.domain.com;
location / {
try_files $uri $uri/ /index.html;
}
location /api/ {
proxy_pass http://localhost:5000;
}
location /api/signalr {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $http_connection;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
location /ws{
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_pass http://localhost:5000;
}
}
和 nginx.conf
http {
map $http_upgrade $connection_upgrade{
default upgrade;
'' close;
}
upstream websocket{
server my.domain.com;
}

# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
##

}
有什么建议可以调试我的配置以查看请求未正确重定向的原因吗?
通过将上游添加到我的 nginx.conf 文件中找到了解决方案。
http {
map $http_upgrade $connection_upgrade{
default upgrade;
`` close;
}
upstream websocket{
server 127.0.0.1:58550;
#SERVER endpoint that handle ws:// connections
}
server{
#Now you can connect via ws:// protocol on ws://yourdomainaddress:8020/ws
listen 8020;
location /ws {
proxy_pass http://websocket;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
}
}
希望有人觉得它有用:)
我想使用使用
的 WebSocketws://mydomain.com/ws
upstream {…}
指令来实现,如您的答案中所示,但您也可以修改原始的location /ws {…}
指令,如下所示:
location /ws {
# … 3 unchanged lines omitted …
proxy_pass http://localhost:5000/ws;
}
唯一的变化是将
/ws
附加到 proxy_pass
URI。这是必要的,因为当 Nginx 构造代理 URI 时,location /ws {…}
匹配的路径前缀会自动删除。因此,当想要保留它时,我们必须将其重新添加到代理 URL 的开头,如 proxy_pass
指令所提供。
用 Nginx
proxy_pass
文档的话来说:
如果使用 URI 指定 proxy_pass 指令,则当请求传递到服务器时,规范化请求 URI 中与位置匹配的部分将被 [proxy_pass] 指令中指定的 URI 替换
