Detailed Description

In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.

The embodiment of the page construction method provided by the specification comprises the following steps:

referring to fig. 1, which shows a processing flow diagram of a page construction method provided in this embodiment, referring to fig. 2, which shows a schematic diagram of a backtracking page provided in this embodiment, referring to fig. 3, which shows a processing flow diagram of a page construction method applied to a security project scenario provided in this embodiment, referring to fig. 4, which shows a processing flow diagram of a page construction method applied to an asset management service scenario provided in this embodiment.

Referring to fig. 1, the page building method provided in this embodiment includes steps S102 to S108.

Step S102, obtaining the service key information and the access process data of the target service.

The page construction method provided by this embodiment starts from access process data recorded for a business process and a business page involved in a business process of a user and stored business key information, and performs "restore" on the business process and the business page involved in the business process of the user, so that the business participation process and access operation submitted by the user in the business process are visually displayed through the business page, and simultaneously, in the process of displaying the business page after the "restore", the stored business key information and the access operation submitted by the user in the business process are synchronously and dataelectrically displayed, thereby realizing traceability of the business participation process of the user and improving perception degree and trust degree of the user for business participation traceability.

The target service in this embodiment refers to an online service that provides a service depending on the internet, such as a guarantee item (e.g., an insurance item) that provides a guarantee service, an online asset management service (e.g., a fund service, a financing service) that provides an asset management service, or an online mutual-aid item that provides a mutual-aid service.

In practical application, in the process of accessing the target service, a user specifically accesses a service page of the target service to obtain specific service information of the target service, so as to determine whether to participate in the target service on the basis of obtaining the service information. For example, during a user's access to a guarantee project, the project page for the guarantee project includes: a project detail page for a project guidance phase, a safeguard detail page for a project participation phase, and a project participation confirmation page for a project confirmation phase.

It should be noted that, in this embodiment, the access process and the participation process of the user accessing and participating in the target service are recorded, and the recording is implemented by calling a process recording interface, where the process recording interface is a service packaged in advance for recording a service page and an access operation, and the triggering of the process recording interface is triggered in the initialization process of the service page of the target service, optionally, the initialization script of the first service page in the first service stage of the target service includes a call function of the process recording interface, and if it is detected that the call function is executed in the execution process of the initialization script of the service page, the call of the process recording interface is triggered.

Further, after the calling of the process recording interface is triggered, the process recording interface is called to record the access process data of the target service, specifically, the process recording interface records the access process data of the target service in the following manner:

reading page element data of the displayed business page;

recording event data of a page event triggered by access operation aiming at the displayed service page;

recording page updating data of an updating service page obtained after the page event is executed;

and determining the page element data, the event data and the page updating data as the access process data of the target service.

In the embodiment, in order to improve the efficiency of data storage and improve the effectiveness and the reliability of data storage, data storage is performed by storing full access process data in a cloud storage space, optionally, the service key information and the access process data are stored in the cloud storage space, and the access process data are stored in the cloud storage space according to the time sequence of the recording time from first to last;

based on this, in the process of acquiring the service key information of the target service and the access process data of the target service, on one hand, the service key information of the target service is read from the cloud storage space, and on the other hand, the access process data of each time unit is sequentially acquired from the cloud storage space by taking the time unit as a unit according to the time sequence of the recording time of the access process data from the beginning to the end, so that in the process of performing the backtracking display on the access process data subsequently, the corresponding page can be backtracked and displayed according to the time sequence.

The access process data comprises page element data of a service page of the target service, event data of a page event triggered by access operation, and page update data of an updated service page obtained after the page event is executed.

The service key information comprises a service key word of the target service and a hash character string of block mapping for storing the service key word in a block chain; wherein the hash string is stored in the cloud storage space. Here, the purpose of setting the hash string in the service key information is to improve the credibility of the user on the access process data of the target service backtrack displayed, and specifically, the hash string indicates that the access process data of the target service is stored by a block chain, so as to embody the validity and authenticity of the access process data of the target service.

And step S104, performing page assembly based on the access process data to obtain an operation page corresponding to the access operation.

As described above, the access process data includes page element data of the service page of the target service, event data of a page event triggered by an access operation, and page update data of an update service page obtained after execution of the page event; on this basis, in an optional implementation manner provided in this embodiment, the page assembly is performed based on the access process data, an operation page corresponding to the access operation is obtained, and the following manner is adopted to implement:

1) assembling an operation page corresponding to the access operation based on the page element data, the event data and the page update data;

2) extracting operation keywords and operation time of the access operation from the event data to form the operation record;

3) establishing a binding relationship between the operation record and the operation page;

4) and extracting the basic page from the page element data.

For example, for a guarantee item, acquiring item key information and guarantee key information of the guarantee item from a cloud storage space, and meanwhile, acquiring access process data from the cloud storage space by taking 30s as a time unit for acquiring the access process data of the guarantee item, after acquiring the first 30s access process data of the guarantee item, on one hand, according to 3 parts of data, namely page element data forming the access process data, event data of a page event triggered by an access operation, and page update data of an update service page acquired after the page event is executed, page assembly of the guarantee item is performed, that is: restoring a project page in the process of recording the guarantee project according to the access process data, and assembling an operation page of the guarantee project in the first 30 s; on the other hand, extracting an operation keyword and operation time of each access operation in the first 30s from the event data of the page event triggered by the access operation; and meanwhile, establishing a binding relationship between the operation key words and the operation time of each access operation and the project page, and in the third aspect, extracting the project page containing the whole page style of the guarantee project from the page element data to prepare for identifying the page key information contained in the project page in the subsequent steps.

And step S106, identifying page key information contained in the basic page in the access process data.

In order to avoid dispute caused by inconsistency between the advertisement information displayed on the service page in the advertisement and sale process of the target service or the sale information and the actual service provided by the target service, in an optional implementation manner provided in this embodiment, in the process of identifying the page key information included in the basic page in the access process data, an OCR recognition technology is used to identify the page key information included in the basic page.

Step S108, based on the business key information, the page key information, the operation page and the operation record extracted from the access process data, a backtracking page corresponding to the access operation is constructed.

The backtracking page corresponding to the access operation in this embodiment includes 3 parts, namely, service backtracking information composed of service key information and page key information, an operation page configured with an operation identifier of the access operation, and an operation record composed of an operation keyword and operation time of the access operation. In addition, a display progress bar and a page identifier are also arranged in the backtracking page, and the total display duration corresponding to the display progress bar is equal to the total record duration of the process access data of the target service; the backtracking page displays page identifiers, and the number of the page identifiers is equal to the number of the service pages of the target service.

In specific implementation, in order to enable a user to more intuitively view access operations and key information of the target service in a process of participating in the target service in advance, in an optional implementation manner provided by this embodiment, on the basis of constructing a backtracking page corresponding to the access operations, backtracking pages corresponding to the access operations are sequentially displayed according to a display sequence of operation time corresponding to the access operations from first to last; and the display time of the backtracking page corresponding to the access operation is synchronous with the operation time of the access operation.

For example, as shown in the backtracking page of the safeguard project shown in fig. 2, the top area is configured with a page identifier of the project page of the safeguard project, the bottom area is displayed with a display progress bar, and the middle area is composed of 3 parts of project backtracking information, an operation page and a user operation record of the safeguard project;

the method comprises the following steps that project backtracking information of guarantee projects displayed in the left area of the middle area specifically comprises 2 parts of project key information of the guarantee projects and page key information identified from a project page containing an integral page style of the guarantee projects by adopting an OCR (optical character recognition) technology;

the operation page displayed in the middle area of the middle area displays the original item page of the guarantee item, and also displays the operation mark in the shape of a small dot point of the access operation of the user on the original item page, so that the access operation of the user on the item page of the guarantee item is displayed more intuitively;

and the user operation record shown in the right area of the middle area specifically records the operation time of the access operation of the user, the page name of the project page targeted by the access operation, the operation name of the access operation and the element name of the page element targeted by the access operation.

It should be noted that the trace-back page corresponding to the access operation implemented in steps S102 to S108 refers to a trace-back page obtained by performing "restore" processing on the access process data of the first time unit (for example, 30S) in the total access process data of the target service, that is, refers to a process of performing "trace-back" on the access operation process of the first time unit in the process of participating in the target service by the user, and since the service key information and the page key information of the target service have been "traced-back" in the "trace-back" process of the first time unit, in the "trace-back" process of the access operation of the subsequent time unit after the first time unit in the total access process data of the target service, there is no need to perform "trace-back" on the service key information and the page key information of the target service again, specifically, in this embodiment, a "backtracking" process of an access operation of a subsequent time unit after a first time unit is described by taking a second time unit as an example, and in an optional implementation manner provided in this embodiment, the "backtracking" process of the access operation of the second time unit is specifically implemented as follows:

acquiring second access process data of the target service in a second time unit after the first time unit;

performing page assembly based on the second access process data to obtain a second operation page corresponding to a second access operation;

and constructing a second backtracking page corresponding to the second access operation based on the service key information, the page key information, the second operation page and a second operation record extracted from the second access process data.

According to the above example, after the first 30s access process data is acquired from the cloud storage space and the corresponding backtracking page is constructed for the security project, on one hand, the constructed backtracking page is displayed, on the other hand, the second 30s access process data is acquired from the cloud storage space, the service assembly is performed by using the acquired access process data, and the backtracking page corresponding to the user access operation in the second 30s access process data is constructed on the basis of the project key information and the security key information acquired from the cloud storage space.

In practical applications, taking a security project as an example, a user often needs to carefully read project details, security terms, and claim settlement agreements of the security project in a process of participating in the security project, so that the time spent from a project detail page entering a project guidance stage of the security project to finally determining the participation in the security project is often long, and generally several time granularities of minutes as a minimum time granularity are required, in this case, in the process of "backtracking" the process of participating in the security project by the user, the play duration of a backtracking page of the security project is consistent with the total duration spent in participating in the security project, which makes it necessary to spend more time to view the displayed backtracking page, and in order to improve the viewing efficiency of the backtracking page and thus improve the convenience of the "backtracking" process, in an optional implementation manner provided by this embodiment, the operation keywords of the access operation displayed through the backtracking page are configured to be triggerable, under the condition that the operation keywords of any access operation in the access operation record are detected to be triggered, the operation page bound with the access operation to which the operation keywords belong is determined, whether a backtracking page corresponding to the access operation to which the operation keywords belong is constructed or not is judged, and if yes, the backtracking page corresponding to the access operation to which the operation keywords belong is displayed; if not, the processing is not required.

In addition, in order to improve the viewing efficiency of the backtracking page, so as to improve the convenience of the backtracking process, the convenience of viewing the backtracking page is improved by setting a display progress bar on the backtracking page, specifically, in an optional implementation manner provided by this embodiment, when it is detected that the display progress bar is triggered, a target progress position after the display progress bar is triggered is determined, and whether a backtracking page corresponding to the target progress position is constructed is determined;

if so, displaying a backtracking page corresponding to the target progress position;

if not, the following operations are executed:

determining a target time unit taking time information corresponding to the target progress position as an initial time point;

acquiring target access process data of the target time unit from access process data stored in the cloud storage space;

performing page assembly based on the target access process data to obtain a target operation page corresponding to target access operation;

constructing a target backtracking page corresponding to the target access operation as a backtracking page corresponding to the target progress position based on the business key information, the page key information, the target operation page and a target operation record extracted from the target access process data;

and displaying a backtracking page corresponding to the target progress position.

The following further describes the page construction method provided in this embodiment by taking an application of the page construction method provided in this embodiment in a guarantee project scenario as an example, and referring to fig. 3, the page construction method applied in the guarantee project scenario specifically includes steps S302 to S316.

And S310, sequentially displaying the backtracking pages corresponding to the access operations according to the display sequence of the operation time corresponding to the access operations from first to last.

And the display time of the backtracking page corresponding to the access operation is synchronous with the operation time of the access operation.

In step S312, second access process data of the security item in a second time unit is obtained.

Step S314, performing page assembly based on the second access process data, and obtaining a second operation page corresponding to the second access operation.

Step S316, constructing a second backtracking page corresponding to the second access operation based on the project key information, the page key information, the second operation page, and the second operation record extracted from the second access process data.

The following further describes the page construction method provided in this embodiment by taking an application of the page construction method provided in this embodiment in an asset management service scenario as an example, and referring to fig. 4, the page construction method applied in the asset management service scenario specifically includes steps S402 to S416.

In summary, according to the page construction method provided by this embodiment, from the acquired access process data and the service key information, the operation page corresponding to the access operation is obtained through page assembly, so that the service flow and the service page of the target service are "restored", and on the basis of the operation page and the page key information obtained through identification, the access operation in the process of the user participating in the target service is "traced back" in a manner of constructing a trace-back page corresponding to the access operation, and meanwhile, synchronous data display of the service key information and the access operation is also realized, so that the perception degree and the trust degree of the user for traceability of service participation are improved.

The second page construction method provided by the specification has the following embodiment:

referring to fig. 5, it shows a processing flow chart of a page building method provided in this embodiment, where the page building method is applied to a client, and specifically includes steps S502 to S508.

reading page element data of the displayed business page;

In this embodiment, in order to improve the efficiency of data storage and improve the validity and reliability of data storage, data storage is performed in a manner of storing full access process data in a block chain, optionally, the service key information and the access process data are stored in blocks of the block chain, the access process data are stored in the blocks according to a time sequence from the beginning to the end of the recording time, and in specific implementation, data is requested by sending a backtracking request of the target service to the block chain nodes.

Step S504, receiving the service key information of the target service and the access process data in the first time unit sent by the blockchain node.

This step receives the service key information of the target service and the access process data in the first time unit, which are sent by the blockchain node. The access process data comprises page element data of a service page of the target service, event data of a page event triggered by access operation, and page update data of an updated service page obtained after the page event is executed.

Step S506, page assembly is carried out based on the access process data, an operation page and an operation record of access operation are obtained, and page key information contained in a basic page in the access process data is identified.

As described above, the access process data includes page element data of the service page of the target service, event data of a page event triggered by an access operation, and page update data of an updated service page obtained after the page event is executed. Based on this, in an optional implementation manner provided in this embodiment, the page assembly is performed based on the access process data, an operation page and an operation record of the access operation are obtained, and page key information included in a basic page in the access process data is identified, which is specifically implemented by the following method:

For example, for a guarantee item, receiving item key information and guarantee key information of the guarantee item issued by a block chain node, and after receiving access process data of the guarantee item issued by the block chain node in the first 30s, performing page assembly of the guarantee item according to page element data forming the access process data, event data of a page event triggered by an access operation, and 3 parts of data of page update data of an update service page obtained after the page event is executed, that is: restoring a project page in the process of recording the guarantee project according to the access process data, and assembling an operation page of the guarantee project in the first 30 s; on the other hand, extracting an operation keyword and operation time of each access operation in the first 30s from the event data of the page event triggered by the access operation; and meanwhile, establishing a binding relationship between the operation keywords and the operation time of each access operation and the project page, and in the third aspect, extracting the project page containing the whole page style of the guarantee project from the page element data, and identifying the page key information contained in the project page by adopting an OCR (optical character recognition) technology.

Step S508, constructing a backtracking page corresponding to the access operation based on the service key information, the page key information, the operation page, and the operation record.

It should be noted that the trace-back page corresponding to the access operation implemented in steps S502 to S508 refers to a trace-back page obtained by performing "restore" processing on the access process data of the first time unit (for example, 30S) in the total access process data of the target service, that is, refers to a process of performing "trace-back" on the access operation process of the first time unit in the process of participating in the target service by the user, and since the service key information and the page key information of the target service have been "traced-back" in the "trace-back" process of the first time unit, in the "trace-back" process of the access operation of the subsequent time unit after the first time unit in the total access process data of the target service, there is no need to perform "trace-back" on the service key information and the page key information of the target service again, specifically, in this embodiment, a "backtracking" process of an access operation of a subsequent time unit after a first time unit is described by taking a second time unit as an example, and in an optional implementation manner provided in this embodiment, the "backtracking" process of the access operation of the second time unit is specifically implemented as follows:

receiving second access process data of the target service sent by the blockchain node in a second time unit after the first time unit;

performing page assembly based on the second access process data to obtain a second operation page corresponding to a second access operation and a second operation record;

and constructing a second backtracking page corresponding to the second access operation based on the service key information, the page key information, the second operation page and the second operation record.

According to the above example, after the first 30s access process data issued by the block chain node is received and the corresponding backtracking page is constructed, on one hand, the constructed backtracking page is displayed, on the other hand, the second 30s access process data issued by the block chain node is received, the obtained access process data is used for service assembly, and on the basis of the project key information and the guarantee key information issued by the block chain node, the backtracking page corresponding to the access operation of the user in the second 30s access process data is constructed.

if not, the following operations are executed:

sending a data acquisition request of the access process data of the target time unit to the blockchain node;

receiving target access process data of the target time unit sent by the blockchain node;

performing page assembly based on the target access process data to obtain a target operation page and a target operation record corresponding to the target access operation;

constructing a target backtracking page corresponding to the target access operation based on the service key information, the page key information, the target operation page and the target operation record, and using the target backtracking page as a backtracking page corresponding to the target progress position;

In summary, in the page construction method provided in this embodiment, access process data and service key information of a target service are requested from block link nodes in a manner of sending a backtracking request of the target service to the block link nodes, an operation page corresponding to an access operation is obtained through page assembly, so that a service flow and a service page of the target service are "restored", and on the basis of the operation page and the obtained page key information, a backtracking page corresponding to the access operation is constructed to perform "backtracking" on an access operation of a user in a process of participating in the target service, and meanwhile, a synchronized data display of the service key information and the access operation is also realized, so that a perception degree and a trust degree of the user in backtracking of service participation are improved.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 30s of the 20 th century, improvements in a technology could clearly be distinguished between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory.
