要在FastAPI中實現API網關,可以使用第三方庫如uvicorn或Starlette來代理請求。以下是一個簡單的示例代碼:
from fastapi import FastAPI
from starlette.middleware.wsgi import WSGIMiddleware
from werkzeug.middleware.proxy_fix import ProxyFix
app = FastAPI()
# Your API routes
@app.get("/api")
async def read_root():
return {"message": "Hello World"}
# Wrap your FastAPI app with ProxyFix to handle request headers correctly
app = WSGIMiddleware(app)
app = ProxyFix(app, x_for=1)
if __name__ == "__main__":
import uvicorn
uvicorn.run(app, host="0.0.0.0", port=8000)
在這個示例中,我們創建了一個FastAPI應用程序,并使用WSGIMiddleware和ProxyFix來實現API網關功能。您可以根據自己的需求和具體情況進行調整和擴展。
