To update request parameters in a FastAPI application, you can use the request: Request parameter in your endpoint function to access the request object. From the request object, you can access the request parameters through the query parameters, path parameters, or request body.
Here are some examples of how you can update request parameters in FastAPI:
- Updating query parameters:
1 2 3 4 5 6 7 8 9 10 11 |
from fastapi import FastAPI, Request
app = FastAPI()
@app.get("/items/")
async def read_items(request: Request):
# Get the query parameters from the request object
params = request.query_params
# Update the value of a query parameter
params["updated_param"] = "new_value"
return params
|
- Updating path parameters:
1 2 3 4 5 6 7 8 9 10 11 |
from fastapi import FastAPI, Request
app = FastAPI()
@app.get("/items/{item_id}")
async def read_item(item_id: int, request: Request):
# Get the path parameters from the request object
params = request.path_params
# Update the value of a path parameter
params["item_id"] = item_id
return params
|
- Updating request body:
1 2 3 4 5 6 7 8 9 10 11 |
from fastapi import FastAPI, Request
app = FastAPI()
@app.post("/items/")
async def create_item(request: Request):
# Get the request body from the request object
body = await request.json()
# Update the request body
body["new_field"] = "new_value"
return body

By using the request object in your endpoint functions, you can easily access and update request parameters in FastAPI.
