这段程序会输出什么？
Python
from fastapi import FastAPI
from fastapi.testclient import TestClient
app = FastAPI()
@app.get("/items/{item_id}")
def read_item(item_id: int, active: bool = False):
return {"item_id": item_id, "active": active}
response = TestClient(app).get("/items/9?active=true")
print(response.status_code, response.json())
