FastAPI-Cache是一个基于FastAPI的缓存扩展,它提供了简单而强大的缓存功能,可以帮助开发者轻松地添加缓存支持到FastAPI应用程序中。
FastAPI-Cache的主要特点包括:
1. 简单易用:FastAPI-Cache提供了简洁的API,使得添加缓存变得非常容易。只需使用装饰器将需要缓存的路由函数标记为缓存即可。
2. 多种缓存后端支持:FastAPI-Cache支持多种缓存后端,包括内存、Redis、Memcached等。你可以根据自己的需求选择适合的缓存后端。
3. 自定义缓存策略:FastAPI-Cache允许你自定义缓存策略,包括缓存过期时间、缓存键的生成方式等。这样你可以根据具体的业务需求来配置缓存策略。
4. 异步支持:FastAPI-Cache完全支持异步操作,可以与FastAPI的异步特性完美结合,提供高性能的缓存功能。

fastapi 详细用法
FastAPI是一个基于Python的现代、快速(高性能)的Web框架,它具有简单易用、高效、自动化文档生成等特点。下面是FastAPI的详细用法[^1]:
1. 安装FastAPI和相关依赖:
```shell
pip install fastapi
```
2. 创建一个FastAPI应用:
```python
from fastapi import FastAPI
app = FastAPI()
```
3. 定义路由和处理函数:
```python
@app.get("/")
def read_root():
return {"Hello": "World"}
@app.get("/items/{item_id}")
def read_item(item_id: int, q: str = None):
return {"item_id": item_id, "q": q}
```
4. 运行FastAPI应用:
```shell
uvicorn main:app --reload
```
5. 访问API文档和交互式界面:
在浏览器中打开 http://localhost:8000/docs 即可查看自动生成的API文档和交互式界面。
6. 使用FastAPI的依赖项(Dependencies):
FastAPI支持使用依赖项来处理请求前的验证、身份验证、数据库连接等操作。可以使用`Depends`装饰器来定义依赖项,并在处理函数中使用它们。
7. 使用FastAPI的缓存功能:
可以使用`fastapi_cache`库来实现简单的轻量级缓存系统。可以通过安装`fastapi-cache`库来使用缓存功能。
以上是FastAPI的一些基本用法,你可以根据自己的需求进一步探索FastAPI的更多功能和特性。
nginx + fastapi
Nginx and FastAPI are two software tools that are commonly used in web development.
Nginx is a web server that can be used as a reverse proxy, load balancer, and HTTP cache. It is known for its high performance and scalability, and is often used to serve static content or to proxy requests to backend servers. Nginx can also be used to improve security by serving as a firewall or by performing SSL termination.
FastAPI, on the other hand, is a modern, fast, web framework for building APIs with Python 3.7+ based on standard Python type hints. It is designed to be easy to use and to provide high performance, making it ideal for building microservices and APIs. FastAPI is also known for its automatic data validation and documentation generation.
When used together, Nginx and FastAPI can provide a powerful and scalable web application stack. Nginx can be used to handle static content and to proxy requests to FastAPI, which can focus on delivering dynamic content and API responses. This allows for efficient resource utilization and can help to improve the overall performance and reliability of the web application.
