這是一個簡單的代碼片斷,不斷重複我遇到的問題。我使用Python 2.7.12,Flask 0.11,Flask-SocketIO 2.7.1和gevent 1.1.2。我知道這可能是一個更好的問題,可以提交給負責包裹的郵件列表,但我無法弄清楚哪一個負責。但是,我很確定這是gevent的問題,因爲這引發了異常。爲什麼Flask + SocketIO + Gevent會給我SSL EOF錯誤?
from flask import Flask
from flask_socketio import SocketIO
from gevent import monkey
monkey.patch_all()
import ssl
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret'
socketio = SocketIO(app, async_mode='gevent')
@app.route('/')
def index():
return "Hello World!"
@socketio.on('connect')
def handle_connect_event():
print('Client connected')
if __name__ == '__main__':
socketio.run(app, host='127.0.0.1', port=8443,
certfile='ssl/server/server.cer', keyfile='ssl/server/server.key',
ca_certs='ssl/server/ca.cer', cert_reqs=ssl.CERT_REQUIRED,
ssl_version=ssl.PROTOCOL_TLSv1_2)
這裏是我得到當客戶端連接錯誤:

我的系統也有OpenSSL的版本1.0.2.j是否有幫助。任何想法,將不勝感激!
這是之前向我報告的(請參閱https://github.com/miguelgrinberg/Flask-SocketIO/issues/88),但從未發現問題所在。這很可能是一個與gevent相關的bug。如果您有可以配置爲終止SSL的代理服務器,您可能可以繞過此問題,因爲我所鏈接的錯誤報告中的人員確實如此。 – Miguel
