带有ssl的Python Gevent Pywsgi服务器 [英] Python Gevent Pywsgi server with ssl

问题描述

我正在尝试使用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.

I'm trying to use gevent.pywsgi.WSGIServer to wrap a Flask app. Everything works fine, however, when I try to add a key and a certificate for ssl, it's not even able to accept any clients anymore.

这是一个引发错误的简单示例:

This is a simple example that throws an error:

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:

我正在使用Python 2.7.13和gevent 1.2.1

I'm using Python 2.7.13 and gevent 1.2.1

重要的是，证书和密钥都是由我生成的.

For what it matters, both the certificate and the key were generated by me.

推荐答案

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

I figured out that the problem was caused by the client sending a regular HTTP request, instead of HTTPS. I just needed to explicitly use a https:// URL in my browser.
