Issue description

I want to configure my parameters in path, how should I configure him? I have configured it now but apisix gives me 404 responses

i am sure that this 404 is not responded to by my backend service

below is the recurrence

• routing config

• apisix 404 response

Environment

In my opinion, my configuration may be consistent with the link you provided. My question may be how to rewrite the uri through regularization. Maybe apisix supports adding uri prefix uniformly?

if value = :token my service can get this request... apisix does not have dynamic routing... I want to get the way how to configure routing correctly

@bnyte What's your need? Could you describe it more concisely and exactly?

[Jixiangup]

@tokers The browser requests /v1/user/login/:username but the request obtained by the backend service is /sso/v1/user/login/bnytezz now request /v1/user/login/bnytezz my service cant get this request but i can get /v1/user/login/:username

Sorry, my English is not good, I use Chinese now to retell

我在apisix配置了/v1/open/user/auth/:token这个路由，本质上这个:token应该是路由参数，但是在我发起请求时如果请求/v1/open/user/auth/dasjkdjahbduq我的服务无法成功接收到请求直接被apisix给404拦截了，但是当我请求/v1/open/user/auth/:token这个时我的服务能接受请求，并且这个路径参数的值就是:token也就是说在这个位置apisix没有去动态路由

did you set

apisix:
    router:
        http: 'radixtree_uri_with_parameter'

This configuration does the trick, thanks for your help, I'll close it now
