一、匹配到的location的关键字不传递给后端
如果想实现访问的url 匹配到的location，不携带给后端服务
类似nginx的配置如下
可以看到 proxy_pass http://chatbot_flask/; 后面是带了"/"的，这代表反向代理给后端的upstream节点不携带"im_chat"这个关键字.
假设我的请求是https://xxx.xxx.com/im_chat/v1/chat/create
当请求到达nginx时，nginx会将/v1/chat/create 这段url反向代理访问后端的节点
location /im_chat {proxy_set_header X-Forwarded-Proto $scheme;proxy_set_header X-Forwarded-Port $server_port;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://chatbot_flask/;proxy_http_version 1.1;proxy_set_header Upgrade $http_upgrade;proxy_set_header Connection $connection_upgrade;proxy_connect_timeout 60s;proxy_send_timeout 60s;proxy_read_timeout 60s;proxy_buffering off;}重点来了对应的k8s ingress nginx 的配置如下：
apiVersion: networking.k8s.io/v1
kind: Ingress
