flask-restful

问题 Im looking to make my Flask based API case insensitive for all incoming payloads. rather than having to apply this to all api-route functions i want to apply this to the @app.before_request decorator, such that for all incoming requests with json payloads (POSTs and PUTs) I directly edit the payload before it is handled by the applicable app.route function. POST {"x":1, "Y":2} Should be formatted to POST {"x":1, "y":2} for request endpoints, but I can't seem to make this happen. @app.before

问题 My model consists in users and books. I want to nest all the books as an array of objects inside each user object, in order to show the books that each user owns. I'm trying to use marshal to nest the books as a list inside the users fields but nothing happens. In the response, there is only the array of users but no track of books and neither of an error. The idea is this: books_fields = { 'id': fields.Integer, 'type' : fields.String, 'created_at': fields.DateTime, 'user_id' : fields.Integer

问题 I'm running Flask Restful on a server in production mode using Python 3.6 and hitting an endpoint that requires jwt auth, but I keep getting a "NoAuthorizationError Missing Authorization Header" error. The strange part is that the very same request is sent using Postman to the local version of the exact same Flask app on my mac and it works just fine without any errors. The problem only occurs on the live server and all of the pip packages are the exact same version as well. UPDATE I am using

问题 I'm building an API, using Flask and flask-restful and flask-swagger-ui. I have now modified the project structure and now I can no longer access the project's swagger.json file. Based on the package documentation flask-swagger-ui, you would only need to change the parameter API_URL to the correct path. But even when entering relative path or full path, I can no longer access the file. My Code : from flask import Flask, jsonify from flask_migrate import Migrate from flask_restful import Api

问题 I need to throw together an very simple API with a short deadline. Flask-restful seems ideal except for one thing: I can't find anything in the documentation about pagination. Given a simple endpoint like this: from flask import Flask, request from flask_restful import Resource, Api from sqlalchemy import create_engine import json app = Flask(__name__) api = Api(app) class Employees(Resource): def get(self): return json.dumps([{'employees': 'hello world'} for i in range(1000)]) api.add

问题 I have the following code to upload an CSV file using Python FLASK. from flask_restful import Resource import pandas as pd ROOT_PATH = os.path.dirname(os.path.abspath(__file__)) class UploadCSV(Resource): def post(self): files = request.files['file'] files.save(os.path.join(ROOT_PATH,files.filename)) data = pd.read_csv(os.path.join(ROOT_PATH,files.filename)) print(data) api.add_resource(UploadCSV, '/v1/upload') if __name__ == '__main__': app.run(host='localhost', debug=True, port=5000) This

问题 I have a ReactJS front end and a flask backend and I am having difficulties making both talk to each other, particular sending form variables from the frontend to Flask. Given below is my front end code which runs on 127.0.0.1:3000 import ReactDOM from 'react-dom'; import React, { Component } from 'react'; class Form1 extends Component{ render(){ return( <div class="form"> <form action="/result" method="get"> <input type="text" name="place" /> <input type="submit" /> </form> </div> ); } }
