How do I get the client port number in a Django pr

问题:

I am using django to build my web server, other people connect to me as clients. Now I need to know the clients' port number to distinguish them. If their browser opens two 'Tabs' of the same link, i.e. two pages but the same link, I also have to distinguish them.

Although I know I can use request.META['REMOTE_ADDR'] to get the client's IP in my django view function, but this realy is not enough for me.

Then I studied some TCP/IP basics and then I know that in TCP/IP layer, every IP packet has an IP header which contains the client's port number. But how can I access it in django?

Additional info:

• I'm using python 2.6 and django 1.4
• I know every TAB of a browser will be allocated a random unique port to access my django web page port. -- see this link 'The web server opens port 80, but the browser has a different, randomly-assigned port.' I really need to distinguish them. So my intuitive thoughts is to use the port number in the IP packet. If you have any other suggestion, also welcome.
• I have found the similar question here, but I am not using Apache now. And this may be hard for me to config so maybe causing other more complex questions. This might make this simple question complex.

1. Your assumption about 'every user connection opens connection at unique port' is wrong. All users are using the same port to connect.
2. To distinguish users Django (and almost every other frameworks) is using sessions. Every user gets a cookie with his unique session ID, and this cookie is passed to a server on every connection, so the application can distinguish users.

Here is documentation on sessions:

Yes, after days of struggling, I answer it, with a working, but ugly solution on 'how to get client port in Django'.

1. in your python26/Lib/SocketServer.py, find def process_request_thread,add global gClientPort; gClientPort = client_address

2. use this global value in yout project. Its format is ('12.34.56.78',55437) for example. 55437 is the port number.

while I debug the django , I find this

request.environ["wsgi.input"].raw._sock.getpeername()

maybe it can work
