Flask

问题 I'm creating a WinJS app and using XMLHttpRequest to send a photo as a blob to a Flask webserver. openPicker.pickSingleFileAsync().then(function (file) { file.openAsync(Windows.Storage.FileAccessMode.read).done(function (stream) { var blob = MSApp.createBlobFromRandomAccessStream("application/octet-stream", stream); var fdata = new FormData(); fdata.append("file", blob, "photo.jpg"); var xmlhttp = new XMLHttpRequest(); xmlhttp.open("POST", "http://127.0.0.1:5000/api/addPhoto", true); xmlhttp

问题 I'm using flask-login https://flask-login.readthedocs.io/en/latest for session management. The user first login in (login.html) the application and go to home.html. However, after the user has authenticated and click different links, it will kick out the session and go back to login page. This happens very randomly and I'm not sure what went wrong? It is using apache. It seems okay with localhost but having this issue in apache. Are there specific apache configurations need to pay attention?

问题 I have a view that takes logged in user input then runs a function to produce a report. The result is returned in an HTML page. I render the report to PDF as well. I create a PDF with the content from my function and save it in some folder on the server. I don't want to have my server filled with files from every run, so I create a temporary folder (in tmpfs) for each user when they log in and save the path in their session, which is not permanent. session['temp_path'] = '/dev/shm/<random

问题 I'm hoping you can help me with errors that I'm getting with Flask in an attempt to deploy plotly-dash on a Windows server. I've set up Flask using the following guide, verbatim, except the location of my website within the wwwroot folder: Flask on IIS When I use the most basic of apps, it works fine, an example being the following code: from flask import Flask app = Flask(__name__) @app.route("/") def hello(): return "Hello from FastCGI via IIS!" if __name__ == "__main__": app.run() But then

问题 So with flask I know that I can add CSS with <link ... href="{{ url_for('static', filename='stylesheets/style.css') }}" /> but if I am adding a google font which usually in HTML looks like <link href='http://fonts.googleapis.com/css?family=PT+Sans:400,700' rel='stylesheet' type='text/css'> what do I need to edit/add for it to work with Flask? 回答1: You can't use static here like you would normally for a link to a resource on the webserver. Your link is still essentially static but not related

问题 I am using Flask and Angular JS to process POST request and I am wondering why the Chrome request header has application/json;charset=UTF-8 compared to FireFox application/json;charset=utf-8 . Note the difference is only the chrome capitalizes UTF while FireFox doesnt (utf). This is probably related to SO: MySQL UTF8 for Chrome, UTF8 for IE, but HEADER UTF8 for Chrome and UTF-8 for IE? but I wasn't able to understand completely. I am not using any meta tag in the html, maybe that is the

问题 I was wondering about the safety of some thing in my app.py flask app. First the database, I'm using mysql and currently I am connecting to it in the following way: # Config MySQL app.config['MYSQL_HOST'] = 'localhost' app.config['MYSQL_USER'] = 'root' app.config['MYSQL_PASSWORD'] = 'password' app.config['MYSQL_DB'] = 'databasename' app.config['MYSQL_CURSORCLASS'] = 'DictCursor' And to me this feels very weird, just putting in your password in plain text etc. I've been searching online but
