|
|
|
|
### How to use libradixtree in APISIX?
|
|
|
|
This is Lua-Openresty implementation library base on FFI for [rax](https://github.com/antirez/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 |
