flask cors和jwt extended一起工作吗

Question

下面的函数出现以下错误。如果我删除jwt_required，它确实有效，所以我猜CORS允许访问。可能是什么问题？

@app.route('/user_authentication/protected', methods=['POST'])
@cross_origin(headers=['Content-Type','Authorization'])
@jwt_required
def protected():
# username = get_jwt_identity()
username = "sana ne "
# response send to Vue page
response = {}
response['user'] = username
print(response)
return jsonify(response), 200

Answer 1

我假设您使用的是flask-jwt-extended>CCD_ 2。一个突破性的改变是将所有视图装饰器移到一个单独的装饰器，这是一个返回装饰器的可调用对象。因此，需要括号。尝试使用jwt_required()
