# 🚀 FastAPI 异步实战：用 Asyncio 提升接口性能

在当今高并发的Web应用场景中，异步编程已成为提升性能的利器！⚡ FastAPI作为Python现代Web框架，原生支持异步请求处理，结合Asyncio可以轻松构建高性能API服务。

## 🌟 为什么选择异步？

传统同步框架在处理I/O密集型操作（如数据库查询、API调用）时会阻塞整个线程，而异步模型允许单个线程同时处理多个请求，显著提高吞吐量！FastAPI基于Starlette异步框架，天生支持async/await语法。

## 🛠️ 实战示例

```python
from fastapi import FastAPI
import asyncio

app = FastAPI()

@app.get("/async-data")
async def get_data():
  # 模拟异步I/O操作
  await asyncio.sleep(1)
  return {"message": "异步数据获取成功！\
