使用flask-mail发送测试邮件时出错

Question

我基本上是在构建一个flask web应用程序，它接受takes强制用户id并返回用户信息。我正试图将flask-mail功能添加到其中，但它显示了

错误：

TypeError:无法解包不可迭代的NoneType对象

错误在mail.send(msg)行中

from flask import Flask, render_template,redirect,request
from flask_mail import Mail,Message
import requests
import json
import os

app = Flask(__name__)
app.config['MAIL_SERVER']='smtp.gmail.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USERNAME'] = 'testdev582@gmail.com'
app.config['MAIL_PASSWORD'] = 'hardik1234'
app.config['MAIL_USE_TLS'] = False
app.config['MAIL_USE_SSL'] = True
#print(app.config.update(mail_settings))
#app.config.update(mail_settings)
mail = Mail(app)

@app.route('/',methods=['GET','POST'])
def index():
    if request.method == 'POST':
        username = request.form['username']
        email_id = request.form.get('email-id')
        msg = Message("test",sender=app.config.get("MAIL_USERNAME"),recipients=[email_id])
        mail.send(msg)
        print(email_id)
        #print(username)
        url = 'http://codeforces.com/api/user.info?handles=' + username
        wvurl = 'http://codeforces.com/api/contest.list?gym=false'
        resp = requests.get(url)
        r = requests.get(wvurl)
        if resp and r:
            user_data = json.loads(resp.text)['result']
            contest_data = json.loads(r.text)['result']
            for contest in contest_data:
                if contest['phase'] == 'BEFORE':
                    break
            print(contest['name'])
            return render_template('show.html',user_data = user_data,contest_data = contest)
        else:
            print("Error in getting response")
            return render_template('index.html')
    return render_template('index.html')

if __name__=='__main__':
    app.run(debug=True)

Answer 1

您将希望使用os.environ

示例：

app.config['MAIL_USERNAME'] = os.environ.get('EMAIL_USER', 'my@email.com')
app.config['MAIL_PASSWORD'] = os.environ.get('EMAIL_PASS', 'mypassword')

或设置环境变量窗口：https://www.youtube.com/watch?v=IolxqkL7cD8 linux：https://www.youtube.com/watch?v=5iWhQWVXosU
