Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.
Fig. 1 is a block diagram of a structure of a method for supporting a mainstream browser to invoke a component, which is described in detail below with reference to fig. 1. The method provided by the application comprises the following steps:
the application layer is used for sending an access request to the middle layer control according to the service function and receiving data returned by the middle layer control;
the middle layer control is used for receiving an access request of the application layer through an HTTP protocol interface and acquiring data from the bottom layer control according to the access request; returning the data of the bottom layer control to the application layer through the HTTP protocol interface, so that the calling of the mainstream browser to the bottom layer control is supported through the middle layer control;
and the bottom layer control is used for providing the requested data to the business function of the application layer.
As can be seen from fig. 1, the application layer is composed of a client and an application server, and an application program located in the application layer sends an HTTP request to the middle layer control through a foreground or a background according to a service function, that is, the client or the application server, and receives data returned by the middle layer control according to the HTTP request, and the received data is also transmitted through an HTTP protocol.
And the middle layer control provides an HTTP protocol interface through packaging the bottom layer control. And the middle layer control adds the service into the system service in the installation process, starts the monitoring port and starts the service, and automatically starts the monitoring port when the operating system is started. And encryption is carried out in the data transmission process, so that the safety of the data is ensured, meanwhile, the access of the middle layer control is authorized, and an authorized user or application program can access the data of the bottom layer control through the middle layer. And when the middle layer control is started, the version of the middle layer control is detected, and if the middle layer control has a new version, the middle layer control can be upgraded.
And the bottom layer control is used for providing the requested data to the service of the application layer. Including reading data stored in an external hardware (tax disk, ukey, etc.) device upon request by the application layer.
The method for supporting the calling of the mainstream browser to the component specifically realizes the service to be provided and the use flow of the calling of the application system to the component is divided into the following steps:
1. encapsulation of middle layer controls to bottom layer controls
The bottom layer control provides access to external hardware equipment (tax disks, ukey and the like), reads certificates and other information in the hardware equipment, and obtains random parameters and enterprise-related information stored in the certificates. The middle layer control further packages the optical fiber, and provides an interface for the outside after packaging. Meanwhile, the middle layer can be further encrypted and authorized, and the legality of the application system for calling the middle layer control is guaranteed.
2. Interface service provided by middle layer control
After the middle layer control is installed, a service is started locally at the client side and an HTTP protocol interface is provided externally, so that direct calling of the bottom layer control is avoided, and the application system accesses the bottom layer control by accessing the middle control service. The intermediate control can be made into exe or other forms, and adds the service to the system service in the installation process, starts the monitoring port and starts the service, and then the service is automatically started along with the start of the operating system.
3. Installation of middle layer controls by application layer system
The application layer system provides an environment detection function on a home page or in a proper position, and detects whether the environment of the local machine meets the requirement of system access. The interface provides a control connection address required to be installed for accessing for the first time, a user finds that the control is not installed during environment detection, the required control can be installed according to requirements, normal access in the later stage of the system can be guaranteed only by installing once under normal conditions, if the plug-in needs to be upgraded, a version update prompt prompting the middle control can be given in the application system, or the middle control is upgraded through an upgrade interface method externally provided by the middle control.
4. Use of underlying controls by application layer systems
For an application system with a B/S structure, two common calling modes for an HTTP interface are provided, wherein one mode is called through a foreground terminal, and the other mode is called through a background server terminal. And neither calling method needs to completely depend on the version and the kernel of the client browser. The network connection of the intermediate control service is only required to be ensured, the application program sends an HTTP request through a foreground or a background to access the intermediate control service, and specifically, the calling of the bottom layer control and the calling of the bottom layer control to the hardware are completed by the intermediate control.
In the process that the application system calls the bottom layer control to obtain the certificate and other related information, the certificate and the like are obtained by calling the middle layer control service, and direct calling of the bottom layer control is avoided. The application layer adopts an HTTP protocol, supports a foreground and background calling mode, does not depend on browser plug-ins and kernel versions, ensures that a system can be accessed by a mainstream browser, meets user requirements, and improves universality and user experience.
In the process that the middle layer control calls the bottom layer control, the complete record of a call log can be added, the data is encrypted in the interface implementation process, and meanwhile, the authorized access interface, the control upgrading interface and other interfaces are added. And the authority processing and more authorization schemes are provided, so that the control on the authority is more flexible and the safety is higher.
For the bottom layer control, the bottom layer control is registered and accessed and called in the implementation process of the interface of the middle layer control, and meanwhile, the calling of the bottom layer control can be further optimized and status is rewritten. More solutions are provided for the registration mode of the bottom-layer component, and the flexibility of the system for component processing is enhanced.
The method provided by the application solves the problem of browser compatibility in the process of calling the bottom layer control by the application system. By adding the intermediate control service to provide an HTTP interface for the outside, the calling of the application system to the bottom layer is converted into accessing the intermediate control service, and meanwhile, the dependence on browser plug-ins is avoided, so that all mainstream browsers are supported. Besides ensuring the support of the main stream browser, the added intermediate control service can also carry out encryption transmission on data acquired from the bottom layer in the program, and ensure the safety, authorization check and the like of information.
Finally, it should be noted that: although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention.
