Abstract
The invention provides a method for passing through a firewall in an instant communication tool, which comprises the following steps that: 1, a client is directly connected with a listening port of aserver firstly; 2, when the connection is failed, the client is connected with the server through a proxy; 3, when the connection is failed in the step 2, the client is connected with the server through a 80 port; and 4, when the server cannot be connected in the three steps, the client encapsulates network data through a http protocol to connect the server and send a http request so as to acquirea response of the server. The client automatically detects and passes through the firewall, so the method can adapt to network environments of most users, and does not influence that the users loginthe server to use the instant communication function.
Description
Technical field:
The present invention relates to Computer Design and applied technical field, particularly relate to a kind of in JICQ the method for passing fire wall.
Background technology
At present, carry out text chat or audio frequency, video conference by immediate communication tool and when live, different agreements sends different data type data.Concrete text chat typically uses that transmission control protocol (TCP) sends, and audio frequency, video conference and livingwage audio frequency, video use User Datagram Protoco (UDP) (UDP) to send usually.The directly server that links with the Internet and communicating by letter by not being subjected to the obstruction of client firewall of carrying out, the operation that signs in on the server can be opened one usually from the return path of server through fire compartment wall.Yet fire compartment wall stops the communication of the client-client of directly carrying out, most of immediate communication tool with earning foreign exchange, listening port that can only the Connection Service device is 1863 as MSN, when fire compartment wall is set, be difficult to break through the restriction of fire compartment wall, cause the client can't the Connection Service device.
Summary of the invention:
The present invention is for addressing the above problem weak point, provide a kind of in JICQ the method for passing fire wall, when user side is provided with acting server or enterprise and is provided with fire compartment wall and has carried out network limits, client is attempted the whole bag of tricks passing fire wall, connect and logon server, finish the function of instant messaging.
May further comprise the steps
The first step: client is the listening port of Connection Service device at first directly;
Second step: when above-mentioned connection failure, then by acting on behalf of the Connection Service device;
The 3rd step: do not connect when second step, client is by 80 port Connection Service devices;
The 4th step: above-mentioned three steps all can't the Connection Service device, and then client is by http protocol encapsulation network data, and the Connection Service device sends the http request, the response of obtaining server.
Described second step comprises that also client detects this machine and whether is provided with the agency, if be provided with the agency, then by acting on behalf of the Connection Service device.
Described the 3rd step, obstructed when the connection of 80 ports, then connect 443 ports.
In the described step 4, use the Http failure, then use Https to connect and send and ask.
Above-mentioned four steps all can not connect, and then need to pass through manual intervention.
Advantage of the present invention:
Client detects and passing fire wall automatically, therefore can adapt to most of user's network environment, does not influence the user login services device and uses instant communication function.
Description of drawings:
Fig. 1 is the flow chart that the present invention realizes an embodiment of document cooperative processing method.
Embodiment:
Central idea of the present invention is, when user side was provided with acting server or enterprise and is provided with fire compartment wall and has carried out network limits, client was attempted the several different methods passing fire wall, connects and logon server, finishes the function of instant messaging.
Realize the prerequisite of several different methods passing fire wall Connection Service device:
A, the user can surf the Net, and does not have network failure;
B, server end support high availability, i.e. two-node cluster hot backup or load balance, and promptly server can break in service;
C, then should add client the tabulation of " allow connect " if this machine of user has fire compartment wall, otherwise client can't the Connection Service device.Some fire compartment wall possesses the function of negotiation, but not all fire compartment wall is all supported.
As shown in Figure 1, a kind of in JICQ the method for passing fire wall, comprise the steps:
101. direct-connected:
No matter whether this machine is provided with the agency, or whether enterprise have fire compartment wall, and client is attempted direct-connected earlier, and promptly the direct listening port of Connection Service device supposes it is 5222.
Under the general networking environment, promptly these users do not use proxy surfing, and fire compartment wall is not provided with the restriction to 5222 yet, can successfully login.
102. connect by the agency:
If direct-connected failure, then client detects this machine and whether is provided with the agency, if be provided with the agency, then by acting on behalf of the Connection Service device.
The enterprise that some is surfed the Net in local area network (LAN) may be by the acting server online, for the user of these enterprises, if firewall restriction is not set, generally can successfully login.103. passing fire wall is to the restriction of server listening port:
If through above 2 steps, still can not the Connection Service device, then may be that enterprise is provided with fire compartment wall at gateway, limited some address or port that local area network (LAN) connects Internet.
Because the user wants browsing page, so at least 80 or 443 ports are open certainly, so client attempts by 80 port Connection Service devices (server is that multiport is monitored, and 5222,80,443 all support), if 80 obstructed, trial connection 443 port then.
For general enterprise firewall, this method can successfully be logined.104. by http (s) protocol encapsulation network data, the Connection Service device:
If above trial still can't the Connection Service device, then might be that enterprise firewall has limited LAN subscriber and can only connect Internet by the http agreement.
Therefore client is by http (s) protocol encapsulation network data, and the Connection Service device sends http (s) request, obtains the response (server end is supported http (s) agreement) of server.
If use the http failure, then use https to attempt connecting and sending request.
105. if through still can't the Connection Service device after the 1-4 step, then client records connects daily record, can't logon server by the interface prompt user, and user's manual intervention, it is wrong etc. to be that network failure, agency are provided with.
Claims (5)
1. the method for a passing fire wall in JICQ is characterized in that:
The first step: client is the listening port of Connection Service device at first directly;
Second step: when above-mentioned connection failure, then by acting on behalf of the Connection Service device;
The 3rd step: do not connect when second step, client is by 80 port Connection Service devices;
The 4th step: above-mentioned three steps all can't the Connection Service device, and then client is by http protocol encapsulation network data, and the Connection Service device sends ht tp request, the response of obtaining server.
2. method according to claim 1 is characterized in that: described second step comprises that also client detects this machine and whether is provided with the agency, if be provided with the agency, then by acting on behalf of the Connection Service device.
3. method according to claim 1 is characterized in that: described the 3rd step, and obstructed when the connection of 80 ports, then connect 443 ports.
4. method according to claim 1 is characterized in that: in the described step 4, use the Http failure, then use Https to connect and send and ask.
5. method according to claim 1 is characterized in that: above-mentioned four steps all can not connect, and then need to pass through manual intervention.
