在使用会话变量之前是否设置了app.secret_key?我有同样的问题,它在本地工作,但在Azure抛出内部服务器错误,因为我把它设置在if _name__ =='_main__'块像这样:
我在if块外面设置了app.secret_key =secret_key p>I have a simple flask web app hosted on Microsoft Azure which allows users to login, upload files, view uploaded files and logout. Now to handle users more efficiently I decided to use session from flask. here is my sample code
'''import statements''' from flask import render_template, request, session '''more import statements''' @app.route('/') def home(): return render_template('login.html') @app.route('/login_user', methods=['GET', 'POST']) def login_user(): username = str(request.form['username']) password = request.form['password'] connection = MongoClient('mongodb://username:password@xyz:pot_number/db_name') collection = connection.db_name.demo record = collection.find_one({'username':username}) if password == record['password']: session['username'] = username return render_template('index.html') else: login_message = "Invalid Username/Password" return render_template('login.html',login_message=login_message) @app.route('/upload', methods=['GET', 'POST']) def upload(): if 'username' in session: return render_template('upload.html') else: return render_template('login.html') @app.route('/logout', methods=['GET', 'POST']) def logout(): session.pop('username',None) return render_template('login.html')whenever i try to add session['username'] = username the app crashes giving a Internal server error.
Im not sure what log file to post since I am new to Azure. Here is the event log

Have you set app.secret_key before using session variable? I had same issue, it worked locally, but threw 'Internal Server Error' in azure, because I set it in if _name__ == '_main__' block like this:
if __name__ == '__main__': HOST = environ.get('SERVER_HOST', 'localhost') try: PORT = int(environ.get('SERVER_PORT', '5555')) except ValueError: PORT = 5555 app.secret_key = "secret_key" app.run(HOST, port=PORT)I set app.secret_key = "secret_key" outside of the if block and it worked.
