you need to install all this stuff

i recommend using a venv

[cerulean lintel]

i did but i opened a new terminal maybe this is the problem

[sturdy oar]

do pip list

[cerulean lintel]

[sturdy oar]

that looks right, ill keep watching :)

have you got this running in the background

(this one has chosen port 8000 not 8080)

[cerulean lintel]

yes

[sturdy oar]

does it say port 8080

[cerulean lintel]

btw i have a diffrenet end poing on my main.py

[sturdy oar]

hmm

you have a leading / in @app.post

try removing that

[cerulean lintel]

should i delete this

from line 5 to 11

[sturdy oar]

replace line 5 with
@app.post("/chatbot-response")

[cerulean lintel]

ok i did

but arent they the same?

[sturdy oar]

things ending in a / are a directory

[cerulean lintel]

ok

[sturdy oar]

idk if it makes a difference, try it

[cerulean lintel]

i did

[sturdy oar]

connection refused suggests that it cant reach the server

you sure its runningon 8080

[cerulean lintel]

how do i know

[sturdy oar]

it should say

Uvicorn running on http://127.0.0.1:8000

[cerulean lintel]

yes i did this step before and it was running

keep watching till he makes a new file called request

and run on a new terminal

[sturdy oar]

on port 8080?

[cerulean lintel]

i forgot

[sturdy oar]

x-x

(check)

[cerulean lintel]

uvicorn request:app --reload?

[sturdy oar]

its running on poort 8000

change in your request file from 8080 -> 8000

[cerulean lintel]

ok done

now i can run python ./request?

[sturdy oar]

yeah

make sure the server is running tho

[cerulean lintel]

how do i do that

[sturdy oar]

have one terminal which looks like this

have another for doing python request

[cerulean lintel]

do i have to change main to request?

[sturdy oar]

im gonna tentativly answer no to that

im not sure what you mean

you have "main" (?) which is the fastapi server (?)

and "request" (?) which does a request to it

[cerulean lintel]

bc i have another file called request which im trying to run but its ok i did it on both and the server working

but on my other terminal which im trying to do python request on. the terminal is stuck it looks like this

i cant write on it

i tried control c

didnt work

[sturdy oar]

you can close on the right tab

idk if that kills the process, you might have to use taskmgr

[cerulean lintel]

UGHHHHHHHHHHHH

[sturdy oar]

is this u rerunning it, or it finaly crashing out

[cerulean lintel]

i closed that terminal and opened a new one and typed python request

and got this

[sturdy oar]

can u give me both main.py and request.py

im gonna try it

[cerulean lintel]

u want a screenshot?

[sturdy oar]

the files

[cerulean lintel]

there u go

[sturdy oar]

ty

works... for me x-x

[cerulean lintel]

u tried running python request?

[sturdy oar]

what i did:

1. put main.py and request.py in a folder
2. python -m venv .venv
3. activate venv
4. pip install fastapi uvicorn requests
5. uvicorn main:app --reload
6. new terminal
7. activate venv
8. python request
9. {'detail': [{'type': 'missing', 'loc': ['query', 'user_message'], 'msg': 'Field required', 'input': None}]}

an error message still but it gave me something

[cerulean lintel]

thank u solly

appreciate ur help

[sturdy oar]

but it doesnt work for you

x-x

[cerulean lintel]

ill cancel my terminals and try do ur steps and let u know

[sturdy oar]

you can try netstat -an | find "8000" (in cmd) to see if the server has actually bound itself to 8000

[cerulean lintel]

when should i try it

[sturdy oar]

after youve run the server and it says "runnin on port 8000"
