Summary of the invention

This application provides a kind of method of port redirection, terminal and server, avoid in server application prior to Port is turned on before port redirection, leads to the abnormal problem of follow-up work.

On the one hand, embodiments herein provides a kind of method of port redirection, which is applied to In cloud interactive system (such as remote virtual desktop system), includes server and user equipment in the cloud interactive system, servicing Mapping relations allocation list is preset in device, which includes at least one PORT BINDING RELATIONSHIP, wherein port can To be that serial ports (mark is generally COM and adds digital number, such as COM1) or parallel port (identify generally LPT and add digital number, such as LPT1), each PORT BINDING RELATIONSHIP records the binding relationship of a virtual port mark and physical port mark, and port is tied up The virtual port mark of relation record is determined for the virtual port in identification server, which is identified as Differentiated services device The unique identification of the virtual port of foundation, the physical port mark of PORT BINDING RELATIONSHIP record are used to identify the physics end of terminal Mouthful, which is identified as the unique identification of the physical port of difference terminal；

At least one application is installed in the server, wherein each application can respectively correspond one or more ports Binding relationship, which includes target application, such as documents editing application word, destination virtual port refer to service The virtual port used in device for target application, target physical port refer to that target application it is expected the physics end used in terminal Mouthful, destination virtual port is corresponding with target physical port, for example, virtual port COM1 is corresponding with physical port COM1, this method Include:

The virtual terminal that server is recorded according to PORT BINDING RELATIONSHIP corresponding with target application in mapping relations allocation list Mouth mark creates destination virtual port, and generates mapping table according to mapping relations allocation list, wherein mapping table packet Include PORT BINDING RELATIONSHIP corresponding with destination virtual port in mapping relations allocation list；

Server is when preset condition meets, in the case where the destination virtual port is opened by target application, according to Mapping table notifies terminal to open target physical port corresponding with the destination virtual port, after terminal receives notice, The corresponding target physical port in destination virtual port is opened, such as destination virtual port COM1 is opened by word, at this point, according to The mapping table can notify terminal to open the corresponding target physical port COM1 of destination virtual port COM1, and terminal receives After notice, i.e. the corresponding target physical port COM1 of unlatching destination virtual port COM1.

The above process, using before opening virtual port, is advanced by creation virtual port, avoids in the server Application turns on virtual port before working normally prior to port redirection in server, leads to the abnormal problem of follow-up work.

In a possible design, server generates mapping table according to mapping relations allocation list, specifically can be Following process is realized:

In terminal login service device, terminal can be sent the port-mark of at least one physical port to server, The port-mark of at least one physical port can be the physical port mark of the port-mark including at least one physical port Know list, server obtains the physical port mark of at least one physical port of terminal, the physical port got from terminal Mark includes that the first physical port identifies, wherein the first physical port mark refers to reflects in the physical port mark got The physical port mark that relationship allocation list record has is penetrated, for example, target physical port is identified with first physical port；

Server ties up the corresponding port of all first physical ports mark institute according to the mapping relations allocation list Determine relationship and inserts mapping table, for example, the port-mark of at least one physical port includes physical port COM1, COM2, In, COM1 is the physical port mark that mapping relations allocation list record has, and COM2 is not recorded, then COM1 is the first physical port Mark, inserts mapping table for the corresponding PORT BINDING RELATIONSHIP of COM1 at this time.

During this, mapping relations allocation list records the physical port mark having in the physical port mark that server is got Know, the corresponding PORT BINDING RELATIONSHIP of all first physical ports mark institute is inserted into the mapping table, realizes binding The mapping of relationship.

In another possible design, the physical port mark got includes that the second physical port identifies, the second object Reason port-mark refers to the physical port mark that mapping relations allocation list does not record in the physical port mark got, i.e., Mapping relations allocation list as described above records the COM2 having；

The method also includes: server creates the port binding of the second physical port mark with default virtual port mark Relationship, and the PORT BINDING RELATIONSHIP of creation is inserted into the mapping table.

Wherein, default virtual port can be in the virtual port that server is created according to mapping relations allocation list, reserve Virtual port, be also possible to preparatory newly created virtual port.

For example, by taking the physical port got is identified as physical port identification list as an example, in physical port identification list It include above-mentioned object such as in port information list when the middle physical port mark not recorded there are the mapping relations allocation list It further include physical port mark COM 3, COM4 in port information list, due to upper on the basis of managing port-mark COM1, COM2 State the binding of the virtual port of physical port mark COM3, COM4 and server side for not having terminal side in mapping relations allocation list Relationship, it is therefore desirable to create or distribute to again the corresponding virtual port of physical port COM 3, COM4, the binding for creating them is closed System, and the PORT BINDING RELATIONSHIP of creation is inserted into mapping table.

When being identified in physical port identification list there are the physical port that the mapping relations allocation list does not record, also The mark for the virtual port that server is created according to mapping relations allocation list and the second physical port mark can be bound, without With new virtual port is created again again, for example, the object of the virtual port mark not specified terminal side COM2 of above-mentioned server side Port is managed, does not have direct virtual port to correspond to since the physical port of terminal side identifies COM3, then the physical port of terminal side Mark COM3 preferentially can go matching to bind from idle virtual port mark, can match virtual port mark COM2 herein, when When server side leisureless virtual port mark, it can just go to create new virtual port and identify to the physical port mark of terminal side Know COM3 matching.

In this way, server is for the physics that does not record of mapping relations allocation list described in the physical port mark that gets Port-mark can create corresponding PORT BINDING RELATIONSHIP, and be added to mapping table.

In another possible design, preset condition satisfaction refers to the automatic connection switch in the preset port of the server It is in close state, wherein the automatic connection switch in port has opening state and closed state two states.
