100% 成功率 Remove or comment out the duplicate route
```
# Remove the second @app.get('/items') decorator
```

100% 成功率 Use different HTTP methods or paths

@app.get('/items')
def list_items(): ...
@app.post('/items')
def create_item(): ...

常见但无效的做法:

Renaming one function without changing the route 100% 失败
The route path and method are still duplicated.
Adding a prefix to one route manually 80% 失败
If the prefix doesn't change the full path, duplication persists.
