我想用gevent.pywsgi.WSGIServer包装Flask应用程序。一切正常,但是,当我尝试为ssl添加密钥和证书时,它甚至无法再接受任何客户端。

这是一个引发错误的简单示例:

from gevent.pywsgi import WSGIServer
from flask import Flask

app = Flask(__name__)
app.debug = True

@app.route('/')
def index():
    """
    Renders the homepage.
    """
    return render_template('index.html')

if __name__ == "__main__":
    app.config["SECRET_KEY"] = "ITSASECRET"
    http_server = WSGIServer(('localhost', 5000), app, keyfile='key.pem', 
certfile='cert.pem')
    http_server.serve_forever()

这是错误的堆栈跟踪:

Traceback (most recent call last):
  File "C:\Python27\lib\site-packages\gevent\greenlet.py", line 536, in run
    result = self._run(*self.args, **self.kwargs)

我正在使用Python 2.7.13和gevent 1.2.1

重要的是,证书和密钥都是由我生成的。

我发现问题是由客户端发送常规HTTP请求而不是HTTPS引起的。我只需要https://在浏览器中显式使用URL。
