Tornado obtains the client device information and IP address, tornadoip

The first blog about how to obtain the Client IP address is to get the client IP address in Tornado.

View the tornado httpserver. py source code and find that you can directly use self. request. remote_ip to get the client address:

 

    def __str__(self):        if self.address_family in (socket.AF_INET, socket.AF_INET6):            return self.remote_ip        elif isinstance(self.address, bytes):            # Python 3 with the -bb option warns about str(bytes),            # so convert it explicitly.            # Unix socket addresses are str on mac but bytes on linux.            return native_str(self.address)        else:            return str(self.address)    def _apply_xheaders(self, headers):        """Rewrite the ``remote_ip`` and ``protocol`` fields."""        # Squid uses X-Forwarded-For, others use X-Real-Ip        ip = headers.get("X-Forwarded-For", self.remote_ip)        ip = ip.split(',')[-1].strip()        ip = headers.get("X-Real-Ip", ip)        if netutil.is_valid_ip(ip):            self.remote_ip = ip        # AWS uses X-Forwarded-Proto        proto_header = headers.get(            "X-Scheme", headers.get("X-Forwarded-Proto",                                    self.protocol))        if proto_header in ("http", "https"):            self.protocol = proto_header    def _unapply_xheaders(self):        """Undo changes from `_apply_xheaders`.        Xheaders are per-request so they should not leak to the next        request on the same connection.        """        self.remote_ip = self._orig_remote_ip        self.protocol = self._orig_protocol

So I think we can do this:
