Technical Field

The application relates to the technical field of terminals, in particular to a client management method and device.

Background

With the development of internet technology, the application of clients in various fields is more and more popular, and with the continuous update of versions of clients, the users need to perform upgrading operations for the clients.

When a user performs client upgrade, it is difficult to ensure the security of an installation file obtained by the user for upgrading the client, and if the installation file used by the user is illegal, the terminal on which the client is installed may be damaged. In particular, in a client use scenario requiring high security, such as in the financial industry, even if the versions of clients installed in terminals connected to the same service are different, there is a risk of execution of financial transactions.

Therefore, how to uniformly manage the clients in the terminals which are connected through the same server and execute the service together becomes an urgent problem to be solved.

Flow charts are used in this description to illustrate operations performed by a system according to embodiments of the present description. It should be understood that the preceding or following operations are not necessarily performed in the exact order in which they are performed. Rather, the various steps may be processed in reverse order or simultaneously. Meanwhile, other operations may be added to the processes, or a certain step or several steps of operations may be removed from the processes.

For example, the customer service management process in this specification relates to a network architecture of a client management system as shown in fig. 1. The client management system can comprise a server and at least one terminal. The server is communicatively connected to the terminal (e.g., the communication connection may be made via a network). In order to implement the client management process in this specification, a main program for interacting with the server may be installed in each terminal in advance.

For convenience of the description, the client management process in the present description will be described by taking the server and any one of the terminals as an example. The client management process in this specification is performed by a server in a client management system, and may include one or more of the following steps.

S200: the clients required under the condition of processing for each type of service are determined.

In this specification, the pending transactions may be all served as services. The types of services may be divided according to the clients used when processing the services, for example, a service processed by a client may be used as a class of service.

Since the number of terminals included in the client management system in this specification may not be unique, the service involved in this step may be the sum of all clients required for service processing by all terminals.

The client in this specification is a program that provides a local service to a user. The client is generally installed on a terminal of a user and needs to be operated in cooperation with the server. In order to meet different service requirements, a plurality of clients are generally installed in one terminal.

S202: and generating an index according to the information of each client.

The information of the client in this specification shows at least information required by the terminal when the client is installed. For example, the information of the client may be at least one of a name, a version number, a storage path in the server, a category, and description information.

After the index is obtained, the index may be searched for the client-side information shown in the index to determine the storage location of the installation file of the client-side, and then obtain the installation file.

In an alternative embodiment of the present specification, after determining the required clients, the installation file of each client may be obtained. Since the process in this specification is intended to improve the security of each terminal accessing the client management system and the uniformity of the clients installed in each terminal, the installation file acquired by the server may be an installation file with guaranteed security obtained from a legal way.

In order to enable the client installed in each terminal accessed to the client management system to meet the use requirements of the user, optionally when a new version of the client is detected, the new version of the client installation file is obtained from the new version of the client installation file, and the installation file stored in the server is updated according to the new version of the client installation file.

S204: and when the main program is detected to be called, sending the index to the main program.

The main program in this specification is installed in the terminal, and the main program is at least used for showing at least part of information recorded in the index to a user.

As can be seen from the foregoing, the process of managing the client in the terminal through the process in this specification needs to be completed through interaction between the terminal and the server, and in an alternative embodiment, the terminal may use a main program to trigger the obtaining operation for the index. Specifically, the main program's acquisition of the index may be triggered each time the main program is invoked.

Alternatively, the process may be: when the main program is invoked (for example, an operation performed by the user is invoked), an index acquisition request is generated and sent to the server. After receiving the index acquisition request, the server sends the index to the main program which generates the index acquisition request.

S206: after receiving the index, the main program may expose at least part of the information in the index.

In an alternative embodiment of the present specification, the presentation may be presented to a user using a terminal to which the main program belongs. The user selects the client that he or she wants to install, i.e., the client that he or she wants to install, based on the information shown in the index. Thereafter, the main program generates an installation request according to the user's selection.

In another optional embodiment of the present specification, the main program may automatically determine a client that needs to be installed in the terminal to which the client belongs, and automatically obtain a corresponding installation file from the server. Specifically, the process may be: and the main program compares the information of the client installed in the terminal where the main program is located with the information of the client shown in the index, and determines the installation file of the client needing to be installed by the terminal as a target file according to the comparison result.

For example, if the information of a certain client in the terminal is different from the information corresponding to the client in the index, the installation file corresponding to the client in the server is the target file. For another example, if the index shows that a client is not installed in the terminal, the installation file corresponding to the client in the server is the target file.

After the target file is determined, the main program generates an installation request aiming at the target file and sends the installation request to the server.

After receiving the installation request, the server determines the installation file corresponding to the installation request in each installation file pre-stored in the server, and the installation file is used as a target file and is sent to the terminal generating the main program.

In an alternative embodiment of the present specification, the main program performs installation according to the installation file under the control of the main program after detecting that the terminal receives the installation file.

It should be noted that installation in this specification refers not only to a process of installing an uninstalled client in a terminal into the terminal, but also refers to an update performed for an installed client in the terminal.

After the terminal installs the client under the control of the main program, the terminal can execute service processing according to the installed client.

As can be seen from the above, the client management process in this specification depends on the main program installed in the terminal. A pre-generated main program may be placed on the server. A client management interface is arranged in the terminal, and the client management interface can be realized through windows server 2012R2, NET framework4.5 and IIS. Specifically, after the IIS is installed in the terminal, an IIS site is added, an IIS website is newly added, a website name, an IP address, and a port are filled, and a physical path is set.

And when the server detects that a client management interface in the terminal is called, the server sends the main program to the terminal, so that the terminal connects the client management interface to the received main program indirectly.

In order to facilitate the terminal to manage the client, in an alternative embodiment of the present specification, a plurality of client groups may be set in the client management interface according to a preset grouping rule. After the main program receives the index, for each client group, the client which the client group belongs to is determined from the clients shown in the index. Then, for each client group, the clients subordinate to the client group are shown in the client group. In particular, the resulting client group may be an office software group, a browser group, an instant messaging group, or the like.

In order to improve the security of the client management system in this specification, the client management interface in this specification is an interface for unidirectional data transmission, and the client management interface is configured to receive data from the server. The main program can display information to a user in a webpage form through the client management interface, so that the user cannot upload illegal data to the server through the client management interface.

When the index file is generated, the information of the client may be determined according to a preset index file generation rule, and the information of the client may be: client name, versionNumber, software, icon path (for example, the icon path may be a path for the terminal to access the server through the IIS website address, and the format is htt_pPort), client class, whether running with administrator (part of software default installation path is a under user directory)_ppdata, such as a chrome browser, which is not to be filled in, installation parameters (such as a silent installation parameter, which is commonly known as S and/silent), a start process after the installation of the interception (filling a process name, such as 7zip.

In an optional embodiment of the present specification, to further improve security, the server may generate a public key and a private key according to a preset encryption rule, add the public key to the main program, and send the main program to the terminal. And when the server generates the index, aiming at each client, encrypting the information of the client by adopting the private key. And generating an index according to the encrypted information of each client, so that the terminal decrypts the index according to the public key after receiving the index to obtain the information of the client. It can be seen that, in this embodiment, the user cannot know the information of the client in the server before the main program, and the user cannot modify the data stored in the server, for example, the installation file of the client.

In addition, after the terminal is completely installed at the client, the terminal sends the installation log generated in the process to the server, so that the server can track the installation condition of the client in each terminal.

The process in the description can effectively improve the safety of each terminal in the client management system and avoid hidden danger caused by the fact that a user carries out client installation by himself.

Further, the client management process in this specification is also applicable to a financial scenario in which each terminal is also connected to a business processing system. And the server in the client management system is in communication connection with the service processing system. For each service processed by a terminal involved in the service processing system, the service processing system records information of a client used by the terminal processing the service when processing the service as reference information. And the service processing system sends the obtained reference information to the server. And the server searches the installation log corresponding to the reference information in the installation log, and determines the risk of the service according to the searched installation log and the reference information. And if the business is determined to be the high-risk business, sending an alarm. If the business is lack of low risk business, a notice is sent to the business processing system, so that the business processing system continues to process the business.

Specifically, if the reference information does not match the installation log of the terminal corresponding to the reference information in the service, it is determined that the service corresponding to the reference information is a high-risk service, and if the reference information and the installation log of the terminal corresponding to the reference information match, the service corresponding to the reference information is a low-risk service.

It can be seen that the process method in this specification is based on a client management system, the system includes a terminal and a server, and the method is executed by the server. Under the unified management of the server, each terminal accessed to the client management system can acquire an installation file from the server and install the client, so that the versions of the clients installed in the terminals are the same, the uniformity of the clients installed in the terminals is improved, and the service jointly executed by the terminals can have better compatibility with the terminals. And the server can control the source of the installation file so as to improve the safety when the terminal adopts the client to process the service. The technical scheme in the specification has better performance in the aspects of safety, compatibility and the like, so that the technical scheme in the specification is suitable for various business processing scenes, particularly financial business processing scenes.

The present specification further provides a client management apparatus, which can execute a client management process provided in the above embodiments of the present application.
