|
|
|

### Loading Paths
|
|
```json
|
|
{
|
|

|
|
},
|
|
"/api/users/{id}": {
|
|

### Regex Pattern
|
|
```python

### ID replacement
|
|
```python

|
re.sub(r'/\d+', '/{id}', path) # /users/123 -> /users/{id}
|
|
re.sub(r'/[0-9a-f]{24,}', '/{id}', path) # MongoDB ObjectId
|
|
re.sub(r'/[0-9a-f-]{36}', '/{uuid}', path) # UUID v4
