如何在Python FastAPI中记录原始HTTP请求/响应

from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware
from starlette.requests import Request
from starlette.responses import Response

app = FastAPI()

# 添加CORS中间件，用于处理跨域请求
app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],
    allow_methods=["*"],
    allow_headers=["*"],
)

# 自定义中间件，用于记录原始HTTP请求/响应
@app.middleware("http")
async def log_requests(request: Request, call_next):
    # 记录原始HTTP请求
    request_body = await request.body()
    request_headers = dict(request.headers)
    print("Original Request:")
    print("Method:", request.method)
    print("URL:", request.url)
    print("Headers:", request_headers)
    print("Body:", request_body.decode())

    # 调用下一个中间件或路由处理程序
    response = await call_next(request)

    # 记录原始HTTP响应
    response_body = await response.body()
    response_headers = dict(response.headers)
    print("Original Response:")
    print("Status Code:", response.status_code)
    print("Headers:", response_headers)
    print("Body:", response_body.decode())

    return response

# 路由处理程序
@app.get("/")
async def root():
    return {"message": "Hello, World!"}
