如果你想使用 Flask-RESTful 创建一个异步 Web 服务器,可以使用 Flask-RESTful 的扩展名 flask-restful-async 和 asyncio 库。
以下是创建 Flask-RESTful 异步 Web 服务器的步骤:
1. 安装所需的库
```
pip install flask flask-restful flask-restful-async asyncio
```
2. 导入所需的库
```python
from flask import Flask
from flask_restful import Api, Resource
from flask_restful_async import AsyncFlaskResource
import asyncio
```
3. 创建 Flask 应用程序实例和 Flask-RESTful Api 实例
```python
app = Flask(__name__)
api = Api(app)
```
4. 创建一个异步资源类,继承 AsyncFlaskResource
```python
class AsyncHello(Resource, AsyncFlaskResource):
async def get(self):
await asyncio.sleep(1)
return {"message": "Hello, World!"}
```
5. 将异步资源添加到 Flask-RESTful Api
```python
api.add_resource(AsyncHello, "/hello")
```
6. 运行 Flask 应用程序
```python
if __name__ == "__main__":
app.run()
```
完整代码示例:
```python
from flask import Flask
from flask_restful import Api, Resource
from flask_restful_async import AsyncFlaskResource
import asyncio
app = Flask(__name__)
api = Api(app)
class AsyncHello(Resource, AsyncFlaskResource):
async def get(self):
await asyncio.sleep(1)
return {"message": "Hello, World!"}
api.add_resource(AsyncHello, "/hello")
if __name__ == "__main__":
app.run()
```
