HTTPServer can serve SSL traffic with Python 2.6+ and OpenSSL. To make this server serve SSL traffic, send the ssl_options dictionary argument with the arguments required for the ssl.wrap_socket method, including “certfile” and “keyfile”: HTTPServer(applicaton, ssl_options={ "certfile": os.path.join(data_dir, "mydomain.crt"), "keyfile": os.path.join(data_dir, "mydomain.key"), })
SSL Sample
import os from tornado.httpserver import HTTPServer from tornado.web import Application, RequestHandler from tornado.ioloop import IOLoop class MainHandler(RequestHandler): def get(self): self.write("Hello world!") def main(): application = Application([ (r"/", MainHandler), ]) http_server = HTTPServer(application, ssl_options={ "certfile": os.path.join(os.path.abspath("."), "test.crt"), "keyfile": os.path.join(os.path.abspath("."), "test.key"), } ) http_server.listen(8080) IOLoop.instance().start() if __name__ == "__main__": main()
過程中需要ssl certificate 與 private key,可以用openssl產生,不過過程很繁雜,建議可以利用online tool:Create self-signed SSL certificates online
測試
開啓 http://localhost:8080 遇到錯誤:
ERROR:root:Exception in I/O handler for fd 3 Traceback (most recent call last): File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/tornado-2.0-py2.6.egg/tornado/ioloop.py", line 287, in start self._handlers[fd](fd, events) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/tornado-2.0-py2.6.egg/tornado/stack_context.py", line 159, in wrapped callback(*args, **kwargs) File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/tornado-2.0-py2.6.egg/tornado/httpserver.py", line 294, in _handle_events except ssl.SSLError, err: AttributeError: 'module' object has no attribute 'SSLError'
少了甚麼module嗎?
重裝openssl 0.9.8t -> 不行
安裝ssl package
# pip install ssl ValueError: This extension should not be used with Python 2.6 or later (already built in), and has not been tested with Python 2.3.4 or earlier.python 2.6以後的版本已經內建了
安裝pyopenssl package
# pip install pyopenssl安裝成功,但結果還是一樣。看起來該有的都有了阿!
最後把deploy系統從mac os換到centos 5,一模一樣的步驟就...成功了!上面的問題至今未解...
如果看到這個warning,表示client的request是用http不是https,並不是server的問題唷!
WARNING:root:SSL Error on 7: [Errno 1] _ssl.c:490: error:1407609C:SSL routines:SSL23_GET_CLIENT_HELLO:http request
