I have, for example, this function
I deployed it with VS Code using the following F1
option in VS Code
Nonetheless, when I go to the function app portal, it shows nothing under the functions submenu:
I don't know why I am not being able to see my functions in my function app, what am I missing?
Here is the dummy code of the function:
import azure.functions as func
import logging
import os
from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient
from azure.communication.email import EmailClient
from datetime import timezone, timedelta, datetime
import jwt
import bcrypt
import pymssql
import json
from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient
app = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)
@app.route(route="actualizar_contrasena", auth_level=func.AuthLevel.ANONYMOUS)
def actualizar_contrasena(req: func.HttpRequest) -> func.HttpResponse:
import json
try:
req_body = req.get_json()
username_to_check = req_body.get("username")
password_to_check = str(req_body.get("password"))
# do things
return func.HttpResponse(
json.dumps(
{"access_token": 1, "refresh_token": 1}
),
status_code=200,
)
except Exception as e:
return func.HttpResponse(str(e), status_code=500)
UPDATE
After following @RithwikBoj instructions, I'm in the same situation. I have observed that locally I can't see the functions neither:
This is my host.json
:
{
"version": "2.0",
"logging": {
"applicationInsights": {
"samplingSettings": {
"isEnabled": true,
"excludedTypes": "Request"
}
}
},
"extensionBundle": {
"id": "Microsoft.Azure.Functions.ExtensionBundle",
"version": "[4.*, 5.0.0)"
}
}
And this is my structure:

I realised that the requirements.txt has something wrong with it in the Function App
And the folder structure has not been updated, because I removed the Readme.md a while ago:
UPDATE I have edited the yaml, now it uploads the requirements.txt file correctly
UPDATE 2
I have deleted all imports except os, logging and azure.functions. After that, I can deploy correctly my function. Butm when I for example add import jwt
to the python script, it disappears again. I need to add libraries to the script, that is my main issue
UPDATE 3 Adding the import inside the definition of each function seems to work:
@app.route(route="log_in_user", auth_level=func.AuthLevel.ANONYMOUS)
def log_in_user(req: func.HttpRequest) -> func.HttpResponse:
import json
import jwt # ADDED HERE THE LIBRARY
try:
req_body = req.get_json()
username_to_check = req_body.get("username")
password_to_check = str(req_body.get("password"))
p = jwt.encode({"pass": password_to_check}, "assaasassa", algorithm="HS256")
return func.HttpResponse(
json.dumps(
{"access_token": 1, "refresh_token": 1, "p": p}
),
status_code=200,
)
except Exception as e:
return func.HttpResponse(str(e), status_code=500)
It is now deployed. But when I try to execute it in Azure:
Result: Failure Exception: ModuleNotFoundError: No module named 'jwt'
I have used below code and it got deployed for me and followed below process:
function_app.py:
import azure.functions as func
import logging as ri_lg
import pymssql as chop
from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient
rith = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)
@rith.route(
route="rith_func", methods=["POST"], auth_level=func.AuthLevel.ANONYMOUS
)
def rith_func(req: func.HttpRequest) -> func.HttpResponse:
try:
rith_rq_bdy = req.get_json()
eml = rith_rq_bdy.get("email")
pwd = rith_rq_bdy.get("password")
ri_con = chop.connect(server="rithwik.database.windows.net",user="rithwik",password="RTestpass@2",database="test1")
cho_cur = ri_con.cursor()
cho_cur.execute("UPDATE users SET password = %s WHERE email = %s",(pwd, eml))
ri_con.commit()
return func.HttpResponse("Hello Rithwik, the Password has been updated",status_code=200)
except Exception as f:
ri_lg.error(f"Error: {f}")
return func.HttpResponse(f"Hello Rithwik, there is an error: {f}",status_code=500)
finally:
