FIG. 1 is a flow chart of a method for a data collection and processing system to run multi-version applications in accordance with one embodiment of the present invention.
In one embodiment, the data acquisition and processing system comprises a reverse server, a gateway, a server and a registration center. The various parts of the system may be connected by a network. Fig. 2 is a schematic diagram of a data acquisition and processing system for running multi-version applications according to an embodiment of the present invention.
Fig. 3 is a schematic diagram of a data acquisition and processing system running a multi-version application according to another embodiment of the present invention. As illustrated in fig. 3, the system may also include a static resource server.
As shown in fig. 1, a method for running multi-version application by a data collection and processing system includes, step 101, configuring different instances of an application service at a server, each instance corresponding to one version of an application service, and defining the instances of each version of the application service as belonging to one or more sub-environments; wherein an application provides one or more application services. And 102, adding the identification information of the different instances to the registration center, wherein the identification information of the instances comprises the sub-environment information to which the instances belong. 103, the reverse server receives an application service request, and classifies and forwards the application service request according to the sub-environment information acquired from the application service request; forwarding dynamic service requests in the application service requests to the gateway. And 104, the gateway receives the dynamic service request and acquires the identification information of the corresponding application service instance from the registration center according to the sub-environment information of the application service. And 105, the gateway forwards the dynamic service request to a sub-environment corresponding to the server for processing according to the acquired identification information of the application service instance.
In one embodiment, the data collection and processing system comprises a medical data collection and processing system, each of the applications may correspond to a business function of the medical data collection and processing system, and the business functions of the medical data collection and processing system include, for example, clinical trial medication management and usage electronic data collection, medication alert electronic data collection, clinical trial subject flow management electronic data collection, medical examination verification and assay data collection and processing, and the like.
In step 101, the server includes, for example, a plurality of servers, and the number of the servers can be configured and expanded according to requirements. Different instances of an application service are configured at a server, each instance corresponding to a version of an application service, and an instance of each version of the application service is defined as belonging to one or more Sub-environments (SubEnv). An application provides one or more application services. As mentioned above, an application may correspond to a business function of the system. An application may provide a variety of application services. For example, the application of data collection and processing for medical examination and test can provide different application services for users of the system according to different data types and/or different standards for examination and test. An application service may include different instances, each of which may correspond to a version of an application service. Different versions of the application service can be optimized and updated for business logic, forming different instances accordingly.
In step 102, the identification information of the different instances is added to the registry, and the identification information of the instances comprises the sub-environment information to which the instances belong. The registry comprises, for example, a server.
In one embodiment, the service registration and discovery framework between the registry and the server comprises Eureka, Consul or Zookeeper.
Eureka is a service discovery framework, which is a REST (Representational State Transfer) based service, and is mainly used for positioning middle-layer services to achieve the purposes of load balancing and middle-layer service failover.
When the service registration and discovery framework includes Eureka, sub-context information of different instances is added in metadata (metadata) of a registry side of the framework.
In step 103, the reverse server receives the application service request, and classifies and forwards the application service request according to the sub-environment information obtained from the application service request; forwarding dynamic service requests of the application service requests to the Gateway (Gateway). The gateway may comprise a server. The symbol R in fig. 2 and 3 refers to an application service request.
The reverse proxy is in the opposite direction to the forward proxy, and refers to a server that performs a reverse proxy service, in which an external network user makes requests to an internal server and forwards the requests to a server on the internal network, and then returns a response obtained from the internal server to a client requesting connection.
In step 104, the gateway receives the dynamic service request, and obtains the identification information of the corresponding application service instance from the registry according to the sub-environment information of the application service. The identification information of the instance of the application service may include basic information and sub-environment information to which it belongs. The basic information may include, for example, the location identification of the server on which the instance is running, such as a hostname, an IP address, and a port number. The sub-environment information of the instance can also correspond to different versions of the instance, namely different versions of the application service.
In step 105, the gateway forwards the dynamic service request to a sub-environment corresponding to the server for processing according to the obtained identification information of the application service instance. And forwarding the dynamic service request to a sub-environment corresponding to the server for processing, specifically, running an instance of a corresponding version of the application service to respond to the dynamic service request.
In order to make the discovery and corresponding process of the application service based on the sub-environment information, in some embodiments, after adding the identification information of the different instances to the registry, the identification information of the instances including the sub-environment information to which the instances belong, the method further includes: setting a polling rule for the registry to register and discover the instance of the application service as: and preferably discovering the instance of the application service according to the sub-environment information specified in the application service request. During service polling, the versions of the application services responding to different application service requests are preferentially determined according to the sub-environment information, specifically, the versions of the instances included by the application services.
When the set polling rule preferentially finds the application service instance according to the sub-environment information appointed in the application service request, if the application service instance corresponding to the appointed sub-environment information cannot be found, the application service request is routed (Route) to the application service instance of the default version.
In some embodiments, the system further comprises a static resource server comprising a plurality of static resources, one static resource corresponding to one version of the application service, each static resource defined as belonging to one or more sub-environments. The static resources comprise static page resources, and the static pages comprise pages in html format or js format, and the pages can be displayed in a browser at a Web end for use or interaction. As illustrated in FIG. 2, in an embodiment, static resources may also be deployed on the reverse server.
In an embodiment, the application service request further includes a static service request, and for a static service request in the application service request, the reverse server forwards the static service request to a sub-environment corresponding to the static resource server for processing according to sub-environment information acquired from the application service request.
In some embodiments, the reverse server receiving an application service request and classifying and forwarding the application service request according to the sub-environment information obtained therefrom comprises:
the reverse server receives an application service request sent by a user side, wherein the application service request comprises domain name information;
when the application service request also comprises the required sub-environment information, the reverse server directly classifies and forwards the application service request; the required sub-environment information is configured in advance in a user management module of the data acquisition and processing system;
when the application service request comprises domain name information which is sub domain name information and does not comprise required sub environment information, the sub domain name information is analyzed through a script program to obtain the sub environment information required by the application service request, and the reverse server classifies and forwards the application service request according to the sub environment information required by the application service request.
The user management module comprises, for example, the tenant using the data acquisition and processing system, and more particularly, the medical data acquisition and processing system, and the specific role of the tenant may be an organizer, participant, implementer and/or administrator of a clinical trial or a drug alert, and the like. There may be, for example, multiple different accounts under the same tenant (e.g., enterprise user) to log on and use the system.
The sub-environment information is configured in advance in a user management module of the data acquisition and processing system, for example, a new version of a part of services of the system applicable to data acquisition and processing is developed, and when a small-scale test is performed for testing, the sub-environment information of the application service available to the user can be configured in the user management module according to the user requirement, so that when the reverse server receives the application service request, the application service request can be classified and forwarded according to the sub-environment information in the application service request. The application service request from the user may be transmitted via http protocol to the reverse server, and the sub-context information is for example included in an http header, and the reverse server may forward this information directly to the gateway.
In some embodiments, when the application service request includes domain name information that is sub-domain name information and does not include required sub-environment information, the sub-domain name information is analyzed by a script program to obtain the sub-environment information required by the application service request, and the reverse server classifies and forwards the application service request according to the sub-environment information required by the application service request. This scenario may be the manner in which a developer of the system is developing and testing the system. Different sub-domain name information can be, for example, "real.
In an embodiment, the reverse server may comprise Nginx or Apache. Nginx (engine x) is an HTTP and reverse proxy web server. Apache HTTP Server (Apache for short) is a web Server with open source code, can run in most computer operating systems, and can compile interpreters such as Perl/Python into the Server through simple API extension.
When the reverse server includes Nginx, the script program includes a Lua script program. The Lua script can be called by C/C + + codes and can also call C/C + + functions in reverse, so that the Lua can be widely applied to application programs, and not only can be used as an extension script, but also can be used as a common configuration file.
In some embodiments, different application services of the service end may also call each other, for example, data transfer and function call between different application services are realized. This is also indicated in fig. 2 and 3 by the arrow connection between the application services.
The invention also provides a data acquisition and processing system for running multi-version application, which comprises a reverse server, a gateway, a server and a registration center.

Fig. 3 is a schematic diagram of a data acquisition and processing system running a multi-version application according to another embodiment of the present invention. As illustrated in fig. 3, the system may also include a static resource server.
In some embodiments, the server is configured to include different instances of an application service, each instance corresponding to a version of an application service, the instances of each version of the application service being defined as belonging to one or more sub-environments; wherein an application provides one or more application services. The server side comprises a plurality of servers, and the number of the servers can be configured and expanded according to requirements.
The registry is configured to include identification information of the different instances, the identification information of the instances including sub-context information to which it belongs. The registry comprises, for example, a server.
