centos nginx配置支持WebSocket(signalR)

signalr 默認會調用websocket去鏈接集線器，centos下，用nginx默認設置不支持ws的

因此，必須更改配置，讓nginx經過websocket

 server {
    listen 80;
    server_name admin.mu-booking.com; 
    location / {
        proxy_pass http://127.0.0.1:5000; 
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection upgrade;
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
    }

可是，這樣問題就來了。ws的服務能夠執行了。ajax的請求卻不適合，畢竟ws須要的是長鏈接，ajax的只是短暫的，有返回後鏈接是會關閉的

因此，應該設置多個路徑

server {
    listen 80;
    server_name admin.mu-booking.com; 
    location / {
        proxy_pass http://127.0.0.1:5000; 
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
    location ~/Hub {
        proxy_pass http://127.0.0.1:5000; 
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection upgrade;
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
    }

 

關鍵 

proxy_set_header Connection upgrade，默認key-alive的，改爲upgrade~/Hub這個路徑，這個對應signalr設置的路徑
