Background
The arrival of the Internet and medical age brings great revolution to the medical industry. Especially, the problem of unbalanced medical level in different regions is effectively relieved due to the appearance of a remote diagnosis platform.
In the course of changing from informationized medical to internet medical, medical software is in fact an evolution from a C/S (client/server) architecture to a B/S (browser/server) architecture. In brief, the medical software is installed for each PC (Personal Computer ) machine of doctors, and the medical software can be easily used as long as the PC machine is installed with a web browser. Medical software under the C/S architecture requires a complex installation process and cumbersome environmental configuration, and a large amount of human resources are consumed on the installation configuration. Meanwhile, medical software is often different from common software, and the performance requirement on a PC is very high, so that the cost of Internet medical treatment is increased sharply. Therefore, the Internet medical treatment under the B/S architecture reduces the use cost, so that medical resources can be widely applied.
At present, the traditional mode of upgrading the C/S architecture to the B/S architecture is to reconstruct the front end and the back end of the original software, namely, the display end is separated from the server end, a set of display interfaces of the web browser end are redeveloped according to the original interface style, the original server end logic is transplanted to the server end, and finally, the operation mode of using the web browser operation interface by a user and all requests to the server end is changed.
Medical software is different from common program software, and if the mode is adopted for upgrading, the medical software needs to be reconstructed, and the reconstruction cost of the medical software is extremely high, so that the upgrading cost is high.

Because of the specificity of medical software relative to common program software, when medical software adopts a traditional mode of upgrading from a C/S architecture to a B/S architecture, there are the following problems:
medical software is often the same in the complexity of the interface as the server program, and the technical resources required for reconstructing the medical software into the web browser are huge;
traditional medical software may not be well compatible with network interface protocols in programming language, and upgrading to cloud environment is difficult;
a set of traditional and complex medical software is transformed according to the existing internet mode, so that the time cost is huge, and the requirement of quick response cannot be met.
The proposal provided by the embodiment of the invention aims at reducing the research and development cost of medical software from a C/S architecture to a B/S architecture. Of course, the scheme provided by the embodiment of the invention is not only suitable for upgrading the medical software from the C/S architecture to the B/S architecture, but also suitable for upgrading other software from the C/S architecture to the B/S architecture.
The application method of the client program in the cloud environment is described in detail below through embodiments.
Fig. 1 is a diagram illustrating an exemplary configuration of an application system of a client program in a cloud environment according to an embodiment of the present invention. As shown in fig. 1, in this embodiment, an application system of a client program in a cloud environment may include a user host, a server, and at least one cloud host, where a browser is deployed on the user host, and a client program and a remote service interface are deployed on the cloud host. Wherein:
The browser on the user host is used for generating a remote connection request according to the input information of the user and sending the remote connection request to the server; establishing remote connection with the target cloud host according to the link address sent by the server, and operating a client program on the target cloud host based on the remote connection;
the server is used for selecting a target cloud host from at least one cloud host of the system according to the remote connection request, sending a remote connection opening request to a remote service interface on the target cloud host, and sending a link address returned by the target cloud host to a browser on the user host;
and the cloud host is used for starting a remote service interface of the host according to the remote connection opening request when the cloud host is selected as the target cloud host, and returning the link address of the remote service interface of the host to the server.
Fig. 2 is a structural example diagram of a cloud host according to an embodiment of the present invention. As shown in fig. 2, a client program and a remote service interface are deployed on a cloud host.
The client program may be a medical software program or other functional software programs.
The remote service interface may be any remote service interface that is available and may be available later.
The at least one cloud host may all belong to the same cluster or may belong to different clusters. For example, as shown in fig. 1, cloud hosts 1 to m belong to cluster 1, and cloud hosts m+1 to 2m belong to cluster 2. When belonging to different clusters, the number of cloud hosts included in the different clusters may be the same or different. Herein, a cloud host is also referred to as a node.
Fig. 3 is a diagram illustrating another structural example of an application system of a client program in a cloud environment according to an embodiment of the present invention. As shown in fig. 3, compared with fig. 1, in this embodiment, the application system of the client program in the cloud environment may further include cloud storage.
In an exemplary implementation process, the server may be further configured to generate a target authentication code corresponding to the user host, and send a data loading request to client software on the target cloud host, where the data loading request includes the target authentication code and a user identifier; the authentication code included in the authentication request sent by the target cloud host is compared with the target authentication code, and if the authentication code is consistent with the target authentication code, authentication passing information is sent to client software on the target cloud host;
The cloud host is further configured to extract the target authentication code from the data loading request after receiving the data loading request, generate an authentication request according to the target authentication code, and send the authentication request to a server, where the authentication request includes the target authentication code; and the user data acquisition module is used for acquiring corresponding user data from the cloud storage according to the user identification after receiving the authentication passing information.
Referring to fig. 3, the application system of the client program in the cloud environment may further include a cache, a node monitoring center, and a node management center.
In fig. 3, the node monitoring center and the node management center are server-independent devices.
In other embodiments, the node monitoring center and the node management center may also be integrated in the server.
In an exemplary implementation process, the cloud host is configured to send a download request to the node management center after detecting an update of a mirror client program of the node management center; and the method is used for locally installing the updated mirror client program after receiving the updated mirror client program sent by the node management center according to the downloading request.
The node management center is used for receiving a downloading request of the cloud host; and the updated mirror image client program is sent to the cloud host according to the downloading request.
The mirror client program here may include all application programs installed on the cloud host.
In one exemplary implementation, the node management center may also be used to deploy client programs, remote service interfaces, and client service interfaces on the new host (client service interfaces, i.e., application devices of a client program running on the cloud host side described later herein in a cloud environment); and for adding the new host to the system.
After the cloud host is purchased, security information and an IP address of the cloud host are added to the node management center, and the cloud host can be accessed into the system for use.
In one exemplary implementation, the node management center may also be configured to delete at least one cloud host. It should be noted that the deleted cloud host needs to be a cloud host that has been deactivated (i.e., no user is connected to the cloud host). After deletion, the server can not use the cloud host any more to provide the service corresponding to the client program for the user.
Fig. 4 is a schematic diagram of an operating principle of an application system of a client program in a cloud environment according to an embodiment of the present invention.
Based on the application system of the client program in the cloud environment, the embodiment of the invention further provides an application method of the client program in the cloud environment. Fig. 5 is a flowchart illustrating an application method of a client program in a cloud environment according to an embodiment of the present invention. The method is applied to a system comprising a user host, a server and at least one cloud host, wherein a browser is deployed on the user host, and a client program and a remote service interface are deployed on the cloud host. As shown in fig. 5, in this embodiment, the application method of the client program in the cloud environment may include:
s501, a browser on a user host generates a remote connection request according to input information of a user and sends the remote connection request to a server.
S502, the server selects a target cloud host from at least one cloud host of the system according to the remote connection request, and sends a remote connection opening request to a remote service interface on the target cloud host.
S503, according to the remote connection opening request, starting the remote service interface of the host, and returning the link address of the remote service interface of the host to the server.
S504, the server sends the link address to a browser on the user host.
S505, the browser establishes remote connection with the target cloud host according to the link address, and operates a client program on the target cloud host based on the remote connection.
In an exemplary implementation, the method further includes:
the server generates a target authentication code corresponding to the user host;
the server sends a data loading request to client software on the target cloud host, wherein the data loading request comprises the target authentication code and a user identifier;
the client software on the target cloud host generates an authentication request and sends the authentication request to a server, wherein the authentication request comprises an authentication code;
the server sends authentication passing information to client software on the target cloud host if the authentication code included in the authentication request is consistent with the target authentication code;
and after receiving the authentication passing information, the client software acquires corresponding user data from a cloud storage according to the user identification.
According to the embodiment, through authentication, the remote connection with the cloud host in a random link mode can be prevented, and the safety of remote connection use is guaranteed.
In an exemplary implementation, the method may further include:
the client software generates processing result data according to the operation information input by the user through the browser and sends the processing result data to the server;
and uploading the processing result data to a cloud storage by the server for storage.
In the embodiment, cloud storage is performed on the user data of the client software, so that the storage burden of a cloud host is reduced, and the resources of the cloud host are saved.
In an exemplary implementation, the method may further include:
the browser generates a remote connection disconnection request according to the operation information of closing the remote display page of the client program by a user and sends the remote connection disconnection request to the server;
the server sends the remote connection disconnection request to client software on the target cloud host;
and the client software disconnects the remote connection with the browser on the user host according to the remote connection disconnection request and clears the corresponding user data.
According to the method and the device for processing the cloud host, after the user finishes using the client program, user data corresponding to the user after the user finishes using the cloud host can be timely cleared, so that bad experience caused by finding junk data left by the operation of the previous user after a new user is connected is avoided. Meanwhile, the cloud host can be prevented from being occupied all the time, and resource waste is avoided.
In an exemplary implementation, the method may further include:
after the browser on the user host successfully establishes remote connection with the target cloud host, sending page heartbeat to the server at regular time;
the server receives the page heartbeat and stores the page heartbeat into a page heartbeat record corresponding to the target cloud host in a cache;
the server sets an expiration time;
detecting whether the recording time of the current time from the last page heartbeat in the cache exceeds a set number of expiration times;
and if the remote connection state exceeds the preset threshold, sending a disconnection notification to the target cloud host, and setting the state of the target cloud host to be an idle state, wherein the disconnection notification is used for indicating the target cloud host to disconnect the remote connection with the browser on the user host.
For example. Assuming that the browser sends a page heartbeat to the server every 60 seconds, after receiving the page heartbeat, the server stores the page heartbeat into a cache and associates the page heartbeat with a corresponding cloud host; and assuming an expiration time of 70 seconds, the detection time is 2 expiration times. After receiving one page heartbeat, the server starts timing, if the timing duration reaches 70 seconds and the next page heartbeat is not received, the server restarts timing from 0, and when the timing duration reaches 70 seconds again, if the next page heartbeat is not received, the server notifies the cloud host to disconnect from the user, and resources of the cloud host are released.
The method of disconnecting remote connection by monitoring page heartbeat is called a disconnection compensation mechanism, and the mechanism can timely release resources of a cloud host and avoid resource waste.
In an exemplary implementation, the method may further include:
the target cloud host monitors a client program on the host and sends node heartbeat to the cache at regular time when the client program on the host is in an available state;
the server detects the node heartbeat corresponding to the client program on the target cloud host in the cache at fixed time;
and if the server does not detect the node heartbeat after overtime, setting the state of the cloud host to be an unavailable state. At this point, the browser may close the current page or jump to other pages.
The state of a client program in the cloud host is monitored through node heartbeat, so that the cloud host is managed. When the server receives the remote connection request, a target cloud host is selected from the cloud hosts in an available state.
The following describes an application method of the client program in the cloud environment from the server side, the browser side, and the cloud host side, respectively. For details in the following method flows on each side, please refer to the foregoing system and related descriptions in the corresponding method of the system, which are not described herein again.

s603, sending a remote connection opening request to a remote service interface on the target cloud host, and receiving a link address of the remote service interface returned by the target cloud host according to the remote connection request;
and S604, the link address is sent to a browser on the user host, so that the browser establishes remote connection with the target cloud host according to the link address, and operates a client program on the target cloud host based on the remote connection.
In an exemplary implementation process, after sending a remote connection opening request to a remote service interface on the target cloud host, before receiving a link address of the remote service interface returned by the target cloud host according to the remote connection request, the method may further include:
Generating a target authentication code corresponding to the user host;
transmitting a data loading request to client software on the target cloud host, wherein the data loading request comprises the target authentication code and a user identifier;
receiving an authentication request sent by client software on the target cloud host, wherein the authentication request comprises an authentication code;
and if the authentication code included in the authentication request is consistent with the target authentication code, notifying the client software on the target cloud host that authentication is successful, so that the client software loads corresponding user data according to the user identifier.
In an exemplary implementation, after sending the link address to the browser on the user host, the method may further include:
receiving processing result data returned by client software on the target cloud host;
and uploading the processing result data to a cloud storage for storage.
In an exemplary implementation, after sending the link address to the browser on the user host, the method may further include:
receiving a remote connection disconnection request sent by a browser on a user host;
