'Blueprint'对象没有属性'config'

Question

我正在使用烧瓶邮件。但是当我在烧瓶邮件的前端(反应.js(调用其余 api 时，我收到此错误

">

蓝图"对象没有属性"配置">

这是我的烧瓶邮件代码

from flask import Flask,Blueprint
from flask_mail import Mail, Message
app = Blueprint('app', __name__)
app.register_blueprint(url_prefix='/api/v1/SalesLead')
mail=Mail(app)
app.config['MAIL_SERVER']='smtp.gmail.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USERNAME'] = '[e-mail]'
app.config['MAIL_PASSWORD'] = '*****'
app.config['MAIL_USE_TLS'] = False
app.config['MAIL_USE_SSL'] = True
mail = Mail(leadHistoryController)
@app.route("/")
def index():
msg = Message('Sheraspace', sender = '[e-mail]', recipients = ['[e-mail]'])
msg.body = "Hello jh"
mail.send(msg)
return "Sent again"
if __name__ == '__main__':
app.run(debug = True)

蓝图配置有什么解决方案吗？或者我可以在不使用蓝图的情况下在前端使用 rest api？

Answer 1

必须改用flask.current_app。

from flask import current_app
def gen_file_name(filename):
"""
If file was exist already, rename it and return a new name
"""
fielname = current_app.config['UPLOAD_FOLDER'] 
return filename

这里也有类似的问题 蓝图配置(blueprint-config
