燒瓶郵件TypeError：getaddrinfo（）參數1必須是字符串或無

Question

我想在我的web應用程序中使用燒瓶郵件，並且我錯誤地認爲我不太瞭解。遵循了指導原則，無法使其發揮作用。在下面的過程中，我希望應用程序向新的註冊用戶發送電子郵件。

配置：

MAIL_SERVER='smtp.gmail.com', 
MAIL_PORT=465, 
MAIL_USE_SSL=True, 
MAIL_USE_TLS=False, 
MAIL_USERNAME = 'myMail@gmail.com', 
MAIL_PASSWORD = '******' 

查看：

from flask_mail import Mail, Message 
mail = Mail(app) 


@app.route("/send_mail/") 
def send_mail(): 
    msg = Message('Hello', sender = 'myMail@gmail.com', recipients = ['somebody@gmail.com']) 
    msg.body = "This is the email body" 
    mail.send(msg) 

錯誤我得到：

任何想法？

Answer 1

您在配置文件中的設置似乎有一個尾隨逗號，這將使它們成爲元組。 Flask-Mail抱怨傳入getaddrinfo的host值不是一個字符串 - 它很可能是一個元組。

刪除尾隨逗號可能會解決此問題。
