How to add context to HTMLResponse as you can do with TemplateResponse to insert content into the HTML site? Example with TemplateResponse:
return templates.TemplateResponse('index.html', context={'request': request, "Variable1": V1, "Variable2": V2})
And how to add the context here?:
#app.get("/")
def root():
return HTMLResponse(pkg_resources.resource_string(__name__, "index.html"))
You can use jinja to achieve solution to your problem.
from fastapi import FastAPI, Request
from fastapi.responses import HTMLResponse
from fastapi.staticfiles import StaticFiles
from fastapi.templating import Jinja2Templates
app = FastAPI()
app.mount("/static", StaticFiles(directory="static"), name="static")
templates = Jinja2Templates(directory="templates")
#app.get("/items/{id}", response_class=HTMLResponse)
async def read_item(request: Request, id: str):
context = {'request': request, "Variable1": V1, "Variable2": V2}
return templates.TemplateResponse("item.html", context)

I am building a Restful API in Python 3.8 using flask_restful, flask_apispec, and marshmallow. When I enable use_kwargs decorator my app is crushing on a POST with TypeError: post() takes 1 positional argument but 2 were given
I'd appreciate any help in solving this bug.

Thanks!
I had the same issue. The use_kwargs decorator will try to populate and inject the AwesomeRequestSchema object into the post() method: https://flask-apispec.readthedocs.io/en/latest/api_reference.html#flask_apispec.annotations.use_kwargs
To fix, replace
def post(self):
with
def post(self, populated_request_object):
Im trying to get the content-length of FastAPI response on the server side for logging purpose. Is this possible? Thanks.
#app.get("/foo")
async def foo(background_tasks: BackgroundTasks):
data = {"foo": "foo"}
response_content_length = get_content_length()
background_tasks.add_task(log, response_content_length )
return data
You can create your own route by inheriting APIRoute class, now you should be able to log everything, without repeating yourself.
from fastapi import FastAPI, Request, Response, Body, BackgroundTasks, APIRouter
from fastapi.routing import APIRoute
from typing import Callable, List
class ContextIncludedRoute(APIRoute):
def get_route_handler(self) -> Callable:
original_route_handler = super().get_route_handler()
async def custom_route_handler(request: Request) -> Response:
response: Response = await original_route_handler(request)
content_length = response.headers["content-length"]
print(content_length)
return response
return custom_route_handler
app = FastAPI()
router = APIRouter(route_class=ContextIncludedRoute)
#router.post("/dummy")
async def dummy():
return {"foo":"foo"}
app.include_router(router)
from aiogram import Bot
import config
def send_message(message):
operator = Bot(config.operator_token)
operator.send_message(config.user_id, message)
def main():
send_message('hi')
I want to send message to user with id from my config.py (config.user_id). But it's not workinkg. I tried many ways for it but I always got an error.
For example like this
Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x7f94a9b62550>
Unclosed connector
connections: ['[(<aiohttp.client_proto.ResponseHandler object at 0x7f94a98f8040>,
23065.38)]']
connector: <aiohttp.connector.TCPConnector object at 0x7f94a9b3c400>'
If you use aiogram you must use async/await to send message.
bot = Bot(token=TOKEN)
dp = Dispatcher(bot_init)
#dp.message_handler(commands=['test'])
async def process_start_command(message: types.Message):
await bot.send_message(message.from_user.id, "test message") #like this
#await message.answer("test message")
#or like this
Maybe this?!
import asyncio
from aiogram import Bot
import config
async def send_message(message):
operator = Bot(config.operator_token)
await operator.send_message(config.user_id, message)
def main():

from aiogram import Bot, types

await message.reply("Hello\nWrite me something!")
#dp.message_handler(commands=['help'])
async def process_help_command(message: types.Message):
await message.reply("Implementation EchoBot")
#dp.message_handler()
async def echo_message(msg: types.Message):

Actually I am trying to create an API and the result of the API can be used but
The page keeps on loading, and no response is shown.
Response should be a python dictionary send by post function of class processRequestHandler
After using a debugger the lines after response = requests.request('POST',url,headers=headers,data=send_data) are not executed.
The class processRequestHandler is working fine when checked with POSTMAN.
requests.request is a blocking method. This blocks the event loop and prevents any other handlers from running. In a Tornado handler, you need to use Tornado's AsyncHTTPClient (or another non-blocking HTTP client such as aiohttp) instead.
async def post(self):
...
response = await AsyncHTTPClient().fetch(url, method='POST', headers=headers, body=send_data)
See the Tornado users's guide for more information.
I want to build an api which accepts a parameter from the user which is a filepath and then process the file given in that path. The file to be processed is already in the server where the api will be running.
As of now, I have written an api where I have hardcoded the filepath in my code which runs the api. Now, I want to configure my api in such a way that accepts a filepath from the user. My api should accept the path as a parameter and process the file that has been given in the path.
The api code is as follows:
The convert function returns the category of the file.
import ectd
from ectd import convert
from flask import Flask, request
from flask_restful import Resource, Api
#from flask.views import MethodView
app = Flask(__name__)
api = Api(app)
#convert(r'D:\files\67cecf40-71cf-4fc4-82e1-696ca41a9fba.pdf')
class ectdtext(Resource):
def get(self, result):
return {'data': ectd.convert(result)}
#api.add_resource(ectdtext, '/ectd/<result>')
categories=convert(r'D:\files\6628cb99-a400-4821-8b13-aa4744bd1286.pdf')
#app.route('/')
def returnResult():
return categories
if __name__ == '__main__':
app.run(host="0.0.0.0", port=5000)
So, I want to make changes to this code to accept a parameter from the user which will be a filepath and the convert function will process that filepath. I want to know how to make my api accept a filepath parameter from the user.
Trial with requests.args.get:
import ectd
from ectd import convert
from flask import Flask, request
from flask_restful import Resource, Api
#from flask.views import MethodView
app = Flask(__name__)
api = Api(app)
#convert(r'D:\files\67cecf40-71cf-4fc4-82e1-696ca41a9fba.pdf')
class ectdtext(Resource):
def get(self, result):
return {'data': ectd.convert(result)}
#api.add_resource(ectdtext, '/ectd/<result>')
#app.route('/')
def returnResult():
categories=convert(r'D:\files\'.format(request.args.get('categories')))
return categories
if __name__ == '__main__':
app.run(host="0.0.0.0", port=5000)
results in error :
"RuntimeError: Working outside of request context.
This typically means that you attempted to use functionality that needed
an active HTTP request. Consult the documentation on testing for
information about how to avoid this problem."
PRESENT SCENARIO:
I am able to post a filepath to the url. My question is now how do I use this posted url with filepath in my code to trigger my function that takes in the filepath and processes the file. Code to post the filepath:
import ectd
from ectd import convert
from flask import Flask, request
from flask_restful import Resource, Api
#from flask.views import MethodView
app = Flask(__name__)
api = Api(app)
class ectdtext(Resource):
def get(self, result):
return {'data': ectd.convert(result)}
#api.add_resource(ectdtext, '/ectd/<result>')
categories=convert('/home/brian/ajay/files/5ca21af9-5b67-45f8-969c-ae571431c665.pdf')
#app.route('/')
def returnResult():
return categories
#app.route('/', defaults={'path': ''})
#app.route('/<path:path>')
def get_dir(path):
return path
##app.route('/get_dir/<path>')
#def get_dir(path):
# return path
if __name__ == '__main__':
app.run(host="0.0.0.0", port=5000)
