We Are Going To Discuss About Python/FastAPI: how can I get headers or a specific header from my backend API?. So lets Start this Python Article.
Python/FastAPI: how can I get headers or a specific header from my backend API?
- How to solve Python/FastAPI: how can I get headers or a specific header from my backend API?
It's pretty similar, you can do
from fastapi import FastAPI, Request @app.get("/") async def root(request: Request): my_header = request.headers.get('header-name') ...
NOTE: that it's lowercased
Example:from fastapi import FastAPI, Request app = FastAPI() @app.get("/") async def root(request: Request): my_header = request.headers.get('my-header') return {"message": my_header}
Now if you run this app with uvicorn on your localhost, you can try out sending acurlcurl -H "My-Header: test" -X GET http://localhost:8000
This will result in{"message":"test"}
UPD:
if you need to access it in decorator you can use followingdef token_required(func): @wraps(func) async def wrapper(*args, request: Request, **kwargs): my_header = request.headers.get('my-header') # my_header will be now available in decorator return await func(*args, request, **kwargs) return wrapper - Python/FastAPI: how can I get headers or a specific header from my backend API?

It’s pretty similar, you can do
from fastapi import FastAPI, Request
@app.get("/")
async def root(request: Request):
my_header = request.headers.get('header-name')
...
NOTE: that it’s lowercased
Example:
from fastapi import FastAPI, Request
app = FastAPI()
@app.get("/")
async def root(request: Request):
my_header = request.headers.get('my-header')
return {"message": my_header}
Now if you run this app with uvicorn on your localhost, you can try out sending a curl
curl -H "My-Header: test" -X GET http://localhost:8000
This will result in
{"message":"test"}
UPD:
if you need to access it in decorator you can use following
def token_required(func):
@wraps(func)
async def wrapper(*args, request: Request, **kwargs):
my_header = request.headers.get('my-header')
# my_header will be now available in decorator
return await func(*args, request, **kwargs)
return wrapper

Or, as described in the fastapi documentation (https://fastapi.tiangolo.com/tutorial/header-params/):
from typing import Optional
from fastapi import FastAPI, Header
app = FastAPI()
@app.get("/items/")
async def read_items(user_agent: Optional[str] = Header(None)):
return {"User-Agent": user_agent}
this will fetch the user_agent header parameter.
