Description

Method, device, medium and electronic equipment for switching isolated objects

Technical Field

The present disclosure relates to the field of computer security, and in particular, to a method, an apparatus, a medium, and an electronic device for switching an isolated object.

Background

The microservice architecture is a new technology for deploying applications and services in the cloud. The microservice may run in its own program and communicate with an HTTP-type application program interface (API for short) through "lightweight devices". Service exposure can be distinguished from microservice architecture (e.g., exposing an HTTP-type API in existing systems) by the above-described features. In service publishing, many services may be restricted by internal independent processes. If any of the services requires some functionality to be added, the process must be narrowed. In the micro-service architecture, only the required functions need to be added in a specific certain service, and the architecture of the whole process is not influenced. For example, the local modules may be only a part of the project, and may also include horizontal modules (including other modules) and vertical modules (site architecture) to manage, combine, outside the project. Different modules need to be dynamically loaded during running, and the modules in different systems are integrated into one page to run. Therefore, strict isolation is required for modules in the microservice.

In the field of computer security, a sandbox (also known as a sandbox) is a security mechanism that provides an isolated environment for running programs. Often, the process is used as a source of uncertainty, damage, or failure to determine the intent of the process.

Sandboxes may tightly control the resources that programs can access, e.g., sandboxes may provide disk and memory space that is reclaimed soon after use. In sandboxes, network access, access to real systems, reading of input devices are typically prohibited or severely limited. From this perspective, sandboxes are one type of virtualization. And all changes in the sandbox do not cause any loss to the operating system.

Therefore, the sandbox is applied to the update test of the module in the micro service, so that effective module isolation and a real module test environment can be provided. However, if there are N sandboxes, any two sandboxes may have active state exchange, and the possibility of switching these sandboxes is factorial to N, that is, the switching algorithm is required to calculate the cartesian product, and compare and record the change of the information of the two sandbox switching parties, thereby resulting in a very large memory space required for recording the information.

Alternative embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

The first embodiment provided by the present disclosure, that is, an embodiment of a method for switching an isolated object.

The following describes an embodiment of the present disclosure in detail with reference to fig. 1 and fig. 2, where fig. 1 is a flowchart of a method for switching an isolated object according to an embodiment of the present disclosure; fig. 2 shows a switching relationship diagram of an initial node object and an isolated object of a method for switching an isolated object according to an embodiment of the present disclosure.

Step S101, acquiring a switching object node.

Wherein the switching object node is an object node of the initial node object in the object node model tree.

The object node model tree is an access model for the whole program document, the whole program document is represented by a tree structure, each object node of the tree represents a subprogram document, and the connection relation between the object nodes represents the relation of the subprogram documents. The structure of the object node model tree describes the interrelationships of the sub-program documents. The process of converting a program document into an object node model tree is called parsing. After being parsed, the program document is converted into an object node model tree, so that the processing of the program document can be realized through the operation on the object node model tree. The object node model tree not only describes the structure of the document, but also comprises the method and the attribute of the object, and the object nodes and the content of the object node model tree can be conveniently accessed, modified, added and deleted. The object node model tree includes a document object model.

An object node model tree comprising: a document object model or a JavaScript object model. Wherein the document object model comprises a style sheet object model.

The Document Object Model (DOM for short) is a standard programming interface for processing extensible markup language. The method is an Application Program Interface (API) independent of a platform and a language, and can dynamically access programs and scripts and update the content, the structure and the style of www documents.

The DOM is a standard API that handles HTML and XML documents. The DOM provides an access model to the entire document as a tree structure, with each object node of the tree representing an HTML tag or text item within the tag. The DOM tree structure accurately describes the interrelationship between tags in an HTML document. The process of converting an HTML or XML document into a DOM tree is called parsing. The HTML document is converted into a DOM tree after being analyzed, so that the HTML document can be processed through the operation of the DOM tree. The DOM model not only describes the structure of the document, but also defines the behavior of the node object, and the object nodes and contents of the DOM tree can be conveniently accessed, modified, added and deleted by using the method and the attribute of the object.

The style sheet object model is the DOM generated by the style sheet. For example, the style sheet is a cascading style sheet.

Cascading Style Sheets (CSS) is a computer language used to represent file styles such as HTML (an application of standard generalized markup language) or XML (a subset of standard generalized markup language). The CSS can not only statically modify the web page, but also dynamically format elements of the web page in coordination with various scripting languages. The CSS can accurately control the typesetting of element positions in the webpage at a pixel level, supports almost all font and font styles and has the capability of editing webpage objects and model styles.

The JavaScript object model has prototype chains, and each node object can find members in the prototype through the chains.

The embodiment of the disclosure switches the function of the object node at the front end by using the characteristics of the object node model tree.

The initial node object is the node object before switching in the object node model tree.

For example, the object node information of the DOM tree, that is, the attribute of the object node, includes: a tag name, a node type, a node content, a set of parent node objects, a set of child node objects, and a set of sibling node objects. The attributes of the DOM tree nodes give the basic content and structural information of the page.

That is, the isolation object will replace the initial node object of the switch object node after switching, so as to achieve the purpose of switching the node object.

Because modules in the micro-service need strict isolation, the isolation object is adopted to isolate node objects in the embodiment of the disclosure, and the isolation object protects the objects to prevent mutual interference between the objects. For example, the isolated object employs a sandbox to protect the object.

In the field of computer security, a sandbox (also called a sandbox) is a security mechanism, and can provide an isolation environment for running programs. Often, the process is used as a source of uncertainty, damage, or failure to determine the intent of the process.

Sandboxes may tightly control the resources that programs can access. In sandboxes, network access, access to real systems, reading of input devices are typically prohibited or severely limited. From this perspective, sandboxes are one type of virtualization. And all changes in the sandbox do not cause any loss to the operating system.

Therefore, the sandbox is applied to the micro-service, so that the front-end module can be effectively isolated. Avoiding mutual interference.

The switch object information includes information describing the contents of the front-end display, representing an HTML tag or a text item within a tag.

Optionally, after the node of the handover object is obtained, the method further includes the following steps:

in step S101A, the initial node object information is saved.

I.e. to save the attribute information of the original node object. For example, the object node model tree is traversed in a snapshot manner to obtain a switching object node of the initial node object, so that the attribute information of the initial node object is obtained based on the switching object node.

Step S102, obtaining the isolation object information.

Step S103, replacing the initial node object information of the switching object node with the isolation object information.

Each switching is started from the initial node object, so that the system resource consumption caused by the calculation of Cartesian product by a switching algorithm is avoided.

Optionally, the replacing, by the isolated object information, the initial node object information of the switch object node includes the following steps:

step S103-1, removing the initial node object information from the switching object node.

That is, the whole operation of the initial node object information of the switching object node is realized, and the initial node object information is completely removed from the switching object node.

Step S103-2, inserting the isolation object information into the switching object node.

Namely, the whole operation of the subordinate information of the switching object node is realized, and the isolation object information is completely inserted into the switching object node.

Optionally, after replacing the initial node object of the switch object node with the isolation object, the method further includes the following steps:

and step S104, enabling the isolated object to be in an activated state.

The embodiment of the disclosure can realize the switching process under the condition that the front end dynamically operates.

Optionally, after replacing the initial node object information of the switch object node with the isolation object information, the method further includes the following steps:

step S105, obtaining the initial node object information.

And step S106, replacing the isolated object information of the switching object node with the initial node object information.

For step S106, the embodiment of the present disclosure provides two application scenarios.

Scene one

Optionally, the replacing, by the initial node object information, the isolated object information of the switch object node includes the following steps:

step S106-11, the isolation object information is removed from the switching object node.

Namely, the whole operation of the isolation object information of the switching object node is realized, and the isolation object information is completely removed from the switching object node.

Step S106-12, inserting the initial node object information into the switching object node.

That is, the whole operation of the subordinate information of the switching object node is realized, and the initial node object information is completely inserted into the switching object node, so that the aim of restoring is realized.

Scene two

and S106-21, acquiring the isolation object information.

Since the isolated object information is stored under the switching object node of the object node model tree at this time, the obtaining of the isolated object information is to obtain the attribute information of the node object under the switching object node from the switching object node of the object node model tree. For example, the object node model tree is traversed by using a snapshot mode, and a switching object node is obtained, so that the attribute information of the isolated object under the switching object node is obtained.

Wherein the isolated object information includes switching object information.

And S106-22, comparing the difference between the initial node object information and the isolation object information to acquire difference information.

The distinguishing information is information that the initial node object information is different from the isolated object information. For example, the difference information is obtained by comparing the snapshot information of the initial node object with the snapshot information of the isolated object.

Step S106-23, the isolation object information of the switching object node is modified based on the difference information, and the initial node object information is generated.

The scene is only to modify different information, but to retain the same information. When the isolated object information is very large and the discrimination information is very small, the efficiency of handover can be significantly improved.

When the sandbox is switched, the sandbox switching method returns to a virtual initial state first, restores to the field, then enters an activated sandbox state, and only records sandbox information during each switching. The problem that the comparison and the storage of sandbox switching information are overlarge due to the fact that the Cartesian product is calculated by a switching algorithm is solved.
