   Hi, @aijunziaixifu, As the @spacewander answered in https://github.com/apache/apisix/issues/2763, you can write your filter function.
   
   Here, I give you an example, you can have a try.
   ```
   curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '{
       "uri": "/index.html",
       "methods": ["PUT", "GET"],
       "upstream": {
           "type": "roundrobin",
           "nodes": {
               "39.97.63.215:80": 1
           }
       },
       "filter_func": "function(vars)
       local core = require (\"apisix.core\")
       local body, err = core.request.get_body()
       if not body then
           return false
       end
   
       local data, err = core.json.decode(body)
       if not data then
           return false
       end
   
       if data[\"a\"] == \"b\" then
           return true
       end
   
       return false
   end"
   }'
   ```
   
   By the way, I had seen many people have questions about this. May I add this to the document?
