"GET / HTTP/1.1" 405 Method Not Allowed

Question

I had an issue with that I cann't use my Post request in FastAPI , I used the Post request but the terminal displayed the Get request and I don't know why. And when I used the Body(...) to declare the dict type but it looked didn't work

from fastapi.params import Body
from pydantic import BaseModel

app = FastAPI()
# payload : input parameter of the function
# dict: type of data
#  được truyền vào bằng cách sử dụng FastAPI's Body dependency. ... được sử dụng để chỉ định rằng tham số 
# này là bắt buộc và không thể bỏ qua.
@app.post("/create")
def create_posts(payload: dict = Body(...)):
    # It will extract all the field from the body to the dict
    print(payload)
    return {"message": f"successfully created posts: {payload['title']}"}

@app.get("/")
def get_data():
    return {"message": "Hello World"}

Here is my error

How are you calling your endpoint? It looks like you're sending a GET request to your POST endpoint. — M.O., Apr 19 '23 at 09:51
yes, when I use the http://localhost:8000/doc to test the API it works, but I don't understand why I executing a GET request to an endpoint that accepts POST requests although I use the @app.post("/create") — LeThanhDat, Apr 19 '23 at 10:19

Problem is your get method is defined at localhost:8000/ (in case you run the app with uvicorn in default mode)

@app.get("/")
def get_data():
    return {"message": "Hello World"}

So you should send a request like

Instead of

You should use POST instead

Or define something like

@app.get("/create")
def get_data():
    return {"message": "Hello World"}

Your code works just fine. Most probably the only issue is that you in fact don't actually send a POST request. Open http://localhost:8000/docs in your browser and try the request yourself.
