域名不变根据系统判断手机和端脑h5pc自动转发不同请求

同一个域名，手机端和电脑端请求的页面不一样，但是域名要求不变，现在有两个前端代码，分别跑在两个docker里面，一个为app1另外一个是app2，暴露的端口分别是8080，8081,通过nginx将请求反代到两个docker容器中,后端接口端口8082

nginx配置如下

配置一upstream.conf

upstream app1 {    server 127.0.0.1:8080 weight=10;}upstream app2 {    server 127.0.0.1:8081 weight=10;}upstream app3 {    server 127.0.0.1:8082 weight=10;}

nginx配置二web.conf

server  {   listen       80;    server_name  domaincxom;    location / {set $is_mobile http://app1;   #设置一个初始值if ( $http_user_agent ~ "(MIDP)|(WAP)|(UP.Browser)|(Smartphone)|(Obigo)|(Mobile)|(AU.Browser)|(wxd.Mms)|(WxdB.Browser)|(CLDC)|(UP.Link)|(KM.Browser)|(UCWEB)|(SEMC\-Browser)|(Mini)|(Symbian)|(Palm)|(Nokia)|(Panasonic)|(MOT\-)|(SonyEricsson)|(NEC\-)|(Alcatel)|(Ericsson)|(BENQ)|(BenQ)|(Amoisonic)|(Amoi\-)|(Capitel)|(PHILIPS)|(SAMSUNG)|(Lenovo)|(Mitsu)|(Motorola)|(SHARP)|(WAPPER)|(LG\-)|(LG/)|(EG900)|(CECT)|(Compal)|(kejian)|(Bird)|(BIRD)|(G900/V1.0)|(Arima)|(CTL)|(TDG)|(Daxian)|(DAXIAN)|(DBTEL)|(Eastcom)|(EASTCOM)|(PANTECH)|(Dopod)|(Haier)|(HAIER)|(KONKA)|(KEJIAN)|(LENOVO)|(Soutec)|(SOUTEC)|(SAGEM)|(SEC\-)|(SED\-)|(EMOL\-)|(INNO55)|(ZTE)|(iPhone)|(Android)|(Windows CE)|(Wget)|(Java)|(curl)|(Opera)" ) {        set $is_mobile http://app2;}        proxy_pass $is_mobile;        proxy_http_version 1.1;        proxy_set_header Connection "";        client_max_body_size    1000m;        proxy_set_header Host $host;        proxy_set_header X-Real-IP       $remote_addr;        proxy_set_header X-Forwarded-Scheme $scheme;        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;        proxy_redirect off;    }    location /api/ {        proxy_pass http://app3;        proxy_http_version 1.1;        proxy_set_header Connection "";        client_max_body_size    1000m;        proxy_set_header Host $host;        proxy_set_header X-Real-IP       $remote_addr;        proxy_set_header X-Forwarded-Scheme $scheme;        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;        proxy_redirect off;    }    access_log  /var/log/nginx/domain.com.access.log main;    error_log   /var/log/nginx/domain.com.error.log;}

这样就可以根据系统请求不同的页面，如果代码不放在容器，也可以把两个前端目录放在不同的文件夹，变量换成不同文件夹的路径
