ShaoZeMing opened a new issue #4268:
URL: https://github.com/apache/apisix/issues/4268


   @ShaoZeMing I listed an example to explain the reason.
   
   Here are three routes(`A`, `B` and `C`), what is their priority?  
   I think you can talk to me `A` < `B`, and `A` < `C`, it seems fine. 
   
   Between `B` and `C`, who has the highest priority? I think it is not easy to reply to this question.
   The machine cannot accurately determine who has the higher priority at this time. 
   
   ```
   ### router A：only uri
   {
       "uris":[ "/*" ]
   }
   
   ### router B ：uri + host
   {
       "uris":["/*"],
       "hosts":["test-dev-1.apisix.xthktech.cn"]
   }
   
   ### router B ： uri + header
   {
       "uris":["/*"],
       "vars":[
           [
               "http_app-name",
               "==",
               "test-header"
           ]
       ]
   }
   ```
   
   In APISIX, when the URI is the same, additional priority needs to be set. 
   Here is an example, then we know that: B > C > A.
   
   ```
   router A：only uri
   {
       "uris":[ "/*" ],
       "priority": 0
   }
   
   router B ：uri + host
   {
       "uris":["/*"],
       "hosts":["test-dev-1.apisix.xthktech.cn"],
       "priority": 2
   }
   
   router C ： uri + header
   {
       "uris":["/*"],
       "vars":[
           [
               "http_app-name",
               "==",
               "test-header"
           ]
       ],
       "priority": 1
   }
   ```
   
   *note*: the default value of `priority` is zero.

   Sorry, I'm here to bother you again. I did configure A and B according to the method in this document, but did not achieve the effect of B>A;
