问题 I'm trying to install fabric via pip install fabric in order to deploy a flask app on a server. I have the following error : ERROR: Command errored out with exit status 1: command: 'c:\users\alex\appdata\local\programs\python\python38-32\python.exe' 'c:\users\alex\appdata\local\programs\python\python38-32\lib\site-packages\pip\_vendor\pep517\_in_proces s.py' build_wheel 'C:\Users\Alex\AppData\Local\Temp\tmp5bslt539' cwd: C:\Users\Alex\AppData\Local\Temp\pip-install-yyi3arer\bcrypt [...]

问题 I am trying to build a JavaScript function that will build the appropriate embed link for a specified user playlist in Spotify. As of now, I have a session variable in my Flask app title 'playlist_id' that holds the Spotify playlist ID I want and a JavaScript function that should update the src attribute in the iframe element for embedded Spotify playlists. @app.route("/playlist/build", methods=['GET', 'POST']) def build(): if request.method == 'GET': print(request.method) return render

问题 I am new to experimenting with creating API's and I was interested to make an app that returns data in an XML format only on the API post request. The flask-restful code below is just a glorified version of how to do an XML response from the git repo examples to view. from simplexml import dumps from flask import make_response, Flask from flask_restful import Api, Resource def output_xml(data, code, headers=None): """Makes a Flask response with a XML encoded body""" resp = make_response(dumps

问题 I am still in the process of learning how everything works, but I am trying to put together a project that has a table that needs to be sorted. I am using flask to generate the pages, and plan to keep the information for the table stored in sql. For the time being, I am using a hard-coded table of dictionaries that will eventually be converted from this sql database. I have successfully gotten my html page to load the flask table element into a table on the webpage. However, I would like to

问题 I'm deploying a ML model for the first time. I'm using flask-restful to create a rest api and gunicorn as stand-alone WSGI.my project directory has only 2 files , ML_model.py and rApi.py. i installed gunicorn and ran the server using gunicorn -w 4 -b 127.0.0.1:5000 rApi:app and i'm able to use the restAPi. I see many things like .env , .config and wsgi.py files mentioned in tutorials available online. what am I missing. why do i need all those files if i can use the API already? 回答1: I see

问题 I'm trying to setup a light-weight RQ task queue app running in Docker. I keep on getting this error: ValueError: Redis URL must specify one of the following schemes (redis://, rediss://, unix://) When grabbing from environmental variable ( os.getenv() ) it doesn't work, but somehow when hard-coding in redis://redis:6379/0 , it seems to work. However, this is not really a long-term solution in my opinion. I looked at: link1 and link2, but there wasn't really a solution, the thread went dead.

问题 I have a CRUD application where wtforms is being used to populate a series of forms with a 'for' loop to allow users to edit existing data in the DB. I'm using "value=row.XXX" to pre-populate the form with existing data from the DB as a default. This works well for normal StringFields, but doesn't work for SelectField. Can anyone help!? Example html below. The form_edit.group is a SelectField. Annoyingly, when displayed in the form, it defaults to the first item in the 'choices' list rather

问题 I'm struggling to find a solution for streaming synthesized audio from a Python server. The synthesized audio is incrementally generated and returned as a np.float32 NumPy array. It then needs to be transformed from a NumPy array into an MP3 chunk. Finally, the MP3 chunk is served via flask . Here is some pseudo-code: import numpy from flask import Flask from flask import Response app = Flask(__name__) sample_rate = 24000 def pcm_to_mp3(): raise NotImplementedError() def get_synthetic_audio()

问题 I am trying transfer a file from a nestJS API to Python Flask API. This process will be triggered by a POST request (FormData: file) on nest API. Then the nest api should send the file to Python api. The HttpService from nestJS use Axios. So my goal is basically to send file with axios from NodeJS. FormData is not available on node JS so I installed Nmp FormData . Python Python Code, which I think is working properly because Postman request pass without any problems. @app.route('/route',
