flask_mail，郵件卡在線程上，永遠不會發送

Question

我用ssl和flask + socketio，我試圖發送郵件，但由於某種原因，發送郵件不工作。

這裏是我的配置：

app.config['MAIL_SERVER']='smtp.gmail.com' 
app.config['MAIL_PORT'] = 465 
app.config['MAIL_USERNAME'] = 'xxx@gmail.com' 
app.config['MAIL_PASSWORD'] = 'xxx;' 
app.config['MAIL_USE_TLS'] = False 
app.config['MAIL_USE_SSL'] = True 
app.config['DEBUG'] = True 

mail=Mail(app) 

...

，當我使用它：

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

    return "" 

而且這裏的錯誤日誌：

File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 307, in flush self._sock.sendall(view[write_offset:write_offset+buffer_size]) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ssl.py", line 721, in sendall v = self.send(data[count:]) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ssl.py", line 687, in send v = self._sslobj.write(data) error: [Errno 32] Broken pipe

由於某些原因，我無法發送任何內容電子郵件。由於socketio + ssl包裝，它似乎卡住了。所以我不知道如何配置正確的方式

我有同樣的問題，如果你在虛擬機工作檢查ssh端口的網絡連接，在我的情況下，我的工作與vagrant，I爲ssh端口啓用連接，此代碼的工作對我說：

from flask import Flask 
from flask_mail import Mail, Message 

# object Flask and object Mail 

app = Flask(__name__) 
#configuration flask to Mail 
app.config.update(
      MAIL_SERVER = "smtp.gmail.com", 
      MAIL_PORT = 465, 
      MAIL_USERNAME = 'xxx@gmail.com', #user mail 
      MAIL_PASSWORD = 'xxx', 
      MAIL_USE_TLS = False, 
      MAIL_USE_SSL = True, 
      MAIL_DEFAULT_SENDER = 'xxx@gmail.com', #user that will go email) 
mail = Mail(app) 

@app.route("/index") 
def index(): 
    return "ok" 


@app.route("/Test Mail") 
def test_mail(): 
    """route to test email by flask mail.""" 
    msj = "This is a test to send mail with flask." 
    recipients = ["xxxemail@gmail.com"] 
    msg_object = Message("hello", recipients) 
    msg_object.body = "Hello, this email is a test" 
    mail.send(msg_object) 
    return "Sent" 



if __name__ == '__main__': 
    app.run(host="0.0.0.0", port=7000, debug=True) 

此外，您應該驗證是否內置不安全Gmail service功能可能會阻止此登錄嘗試。登錄您的帳戶並訪問https://www.google.com/settings/security/lesssecureapps。
