libradixtree
what's libradixtree?
libradixtree, adaptive radix trees implemented in Lua for OpenResty.
APISIX using libradixtree as route dispatching library.
How to use libradixtree in APISIX?
This is Lua-Openresty implementation library base on FFI for rax.
Let's take a look at a few examples and have an intuitive understanding.
1. Full match
/blog/foo
It will only match /blog/foo
.
2. Prefix matching
/blog/bar*
It will match the path with the prefix /blog/bar
, eg: /blog/bar/a
,
/blog/bar/b
, /blog/bar/c/d/e
, /blog/bar
etc.
3. Match priority
Full match -> Deep prefix matching.
Here are the rules:
/blog/foo/*
/blog/foo/a/*
/blog/foo/c/*
/blog/foo/bar
path | Match result |
---|---|
/blog/foo/bar | /blog/foo/bar |
/blog/foo/a/b/c | /blog/foo/a/* |
/blog/foo/c/d | /blog/foo/c/* |
/blog/foo/gloo | /blog/foo/* |
/blog/bar | not match |
How to filter route by Nginx builtin variable
Please take a look at radixtree-new, here is an simple example:
$ curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
{
"uri": "/index.html",
"vars": [
["http_host", "==", "iresty.com"],
["cookie_device_id", "==", "a66f0cdc4ba2df8c096f74c9110163a9"],
["arg_name", "==", "json"],
["arg_age", ">", "18"],
["arg_address", "~~", "China.*"]
],
"upstream": {
"type": "roundrobin",
"nodes": {
"39.97.63.215:80": 1
}
}
}'
This route will require the request header host
equal iresty.com
, request cookie key _device_id
equal a66f0cdc4ba2df8c096f74c9110163a9
etc.
