   I know, but when multiple upstream addresses are set to ip instead of domain names, it will not take effect.
   
   upstream.nodes：
   ```
       "nodes": [
         {
           "host": "192.168.0.1",
           "port": 80,
           "weight": 1
         },
         {
           "host": "192.168.0.2",
           "port": 80,
           "weight": 1
         }
       ],
   
   ```
