Detailed Description

The embodiment of the specification provides an external service access method, an external service access device, external service equipment and a storage medium.

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments of the present disclosure, shall fall within the scope of protection of the present application.

Fig. 1 is a schematic flowchart of an access method for an external service according to an embodiment of the present disclosure, which specifically includes the following steps:

s101: a plurality of different functional nodes are exposed.

In the embodiment of the present specification, the functional node is a node capable of realizing a specific single function, which is abstracted to have generality, according to the characteristics of the external service through the precipitation of the practical experience of the past external service access.

For example, the communication function node can realize data transmission with the mechanism; the analysis function node can realize the analysis of the mechanism return result message; the signature adding function node can realize signature addition on the input of the user or the output of the cooperation; and various preset functional nodes such as encryption, decryption, signature verification, flow control, node rendering, conversion, combination and the like.

In other words, for each functional node, the functionality that it finally implements is always the same, although it can still be configured individually by the external service access.

For example, query of the hangzhou public accumulation fund and query of the beijing public accumulation fund are services for querying the public accumulation fund, but because the difference of regions is provided by different institutions, for two different public accumulation fund institutions, even though a communication function node is adopted, the message and the related communication address of the interface used by the function node have some differences.

For another example, for the functional node "signing", each external service access party may configure a private key applied in signing adopted in the node, but finally, the input to the node is signed based on the private key configured by the external service access party.

Furthermore, various pre-precipitated functional nodes can be displayed in an interface in a graphical mode so as to be convenient for a service access side to select.

S103, receiving a configuration instruction of a service access party, and generating a function node execution chain, wherein the function node execution chain comprises a plurality of function nodes which are executed in sequence.

The service access party may be a third party of the non-payment platform, for example, may be some of the services provided by various public operating agencies. Such as inquiring the balance of the public deposit, health codes, paying for the water and electricity coal, medical insurance and the like.

The configuration instruction of the service access party can be used for selecting specific functional nodes, determining the sequence of the selected functional nodes, performing content configuration filling and sequence arrangement on the functional nodes, and the like.

Fig. 2 is a schematic configuration diagram of a function node execution chain according to an embodiment of the present disclosure, as shown in fig. 2. The service access party sequentially selects a plurality of displayed functional nodes and can also perform personalized configuration on each functional node, thereby generating a functional node execution chain.

For example, the service access may populate content configurations personalized for each functional node as follows: for the selected function node of 'adding sign', the service access party can pre-configure the private key used in the sign adding process or can call the path for obtaining the private key; alternatively, the service access party may configure the address in the communication process for the selected "communication" function node (the address may be the address required to call to obtain data or the address to send request information at the function node).

For another example, the service access side may perform the following sequential arrangement on each functional node: the service access party can configure the execution sequence of each function node, as shown in fig. 2, among the displayed function nodes, the service access party configures the execution sequence of each function node into an execution sequence of "parsing-converting-tagging-rendering-communicating-parsing-tagging-rendering"; alternatively, the service access side may also configure data input and output between the functional nodes, that is, determine data transmission between the functional nodes.

For another example, the service access side may perform the following data exchange configuration for each functional node: it should be noted that, although each function node is always executed in sequence in the function node execution chain. However, the data executed by each functional node is not required to depend on the execution result of the previous functional node, and a jump may exist between the functional nodes. For example, for the function node "check label" in fig. 2, its input does not depend on the function node before it, such as "render", "communicate" or "parse", but depends on "add label". This also requires the service access to configure, i.e. the configuration instructions can also configure the inputs and outputs of the functional nodes in sequence during data transmission. In fig. 2, it can be shown that the service access party configures the output of the 3 rd functional node "tagging" as the input of the 7 th functional node "tag verification".

And S105, sending the function node execution chain to a gateway so that the gateway can store and load the function node execution chain.

After the function node execution chain is sent to the gateway, the gateway may execute the function node execution chain, for example, the gateway may store a correspondence between the service access party and the function node execution chain. Therefore, the gateway can obtain the function node execution chain of the service access party only when the service access party calls the service of the gateway, and the function node execution chain is loaded and executed to generate a data result. Fig. 3 is a schematic diagram of a logical framework for generating a function node execution chain according to an embodiment of the present disclosure, as shown in fig. 3.

By exposing a plurality of different functional nodes; receiving a configuration instruction of a service access party, and generating a function node execution chain, wherein the function node execution chain comprises a plurality of function nodes which are executed in sequence; and sending the function node execution chain to a gateway so that the gateway can store and load the function node execution chain. The access to the external service can be completed only by arranging the function nodes based on the abstracted function nodes. Therefore, when a large amount of nonstandard external organization services are accessed to the payment platform, program codes do not need to be written, the threshold is reduced, the payment platform can be configured and completed by a business party independently, and the payment platform is more convenient and efficient.

In an embodiment, before sending the function node execution chain to the gateway, a simulation execution result of the function node execution chain may be further shown, so that the service access party adjusts the function node execution chain according to the simulation execution result.

In practical applications, since the function node execution chain is configured in the graphical presentation interface provided by the service access platform, it is actually unknown to the external service access party whether the configuration is correct, and it is necessary to be able to perform testing in the background.

Based on the method, the service access platform can display the arranged capability node execution chain, provide input parameters, execute and directly output an execution result. If abnormity occurs in the simulation process, error prompt information can be displayed, and which functional node appears in the chain is determined, so that the service access party can adjust the functional node execution chain according to the simulation execution result. The adjustment here includes the content configuration filling or the sequential arrangement of the function nodes in the execution chain.

In an embodiment, when the service access platform displays a plurality of different function nodes, the service access platform may also give various different modes of display based on the characteristics of each function node. Specifically, the corresponding form styles required for the atomic capability front-end rendering, including styles such as text, selection, dynamic form, etc., can be described in advance, so that each function node can be rendered into a pre-agreed image based on agreed form description rules.

For example, for a 'tagging' function node, the function node display can be composed of a plurality of forms, and the form style of the function can be defined as a lock-shaped graph, so that the display mode is more intuitive, and the user experience is improved.

For another example, for a functional node that needs to use encryption in the access process, configuration items such as "encryption algorithm type", "text to be encrypted", "encryption result encoding mode" and the like in a form of the node need to be configured, for example, the "encryption algorithm type" item may be described as a style whose display mode is the agreed "selection", and multiple items of encryption algorithm type pull-down selection are provided. Therefore, when the service access side selects the node, the various encryption algorithms provided by the encrypted functional node are displayed in a selectable mode.

In an embodiment, when the function node is rendered and displayed according to the style information, an execution chain template composed of a plurality of function nodes may be rendered and displayed according to the style information. The execution chain template may be provided by the server, or may be obtained by classifying based on the characteristics of the service access party and performing statistics based on the execution chain of the function node adopted by each class.

For example, a service access party can be classified into a query class, a payment class, a security check class and the like based on the industry or the function of the service access party, each service access party can have a respective template, a proper template can be selected during access, and the access can be completed only by slightly adjusting the arrangement.

Taking the accumulation fund as an example, the server may provide a basic template of the accumulation fund including a plurality of functional nodes so as to facilitate selection of each local accumulation fund organization. The service end does not provide any template in advance, and the service end can generate the function node execution chain of each place and access the service for the public accumulation fund institutions of each place.

At this time, if a new accumulation fund mechanism re-applies for access, the function node execution chains adopted by the accumulation fund mechanisms in other places which are executed in a mature manner can be displayed, and sequencing (for example, the execution success rate of the function node execution chains of the accumulation fund machines in other places can be determined, or the times selected by other places can be sequenced) and display are performed, so that a new access party can conveniently select, and the access efficiency of external services can be further improved.

In a second aspect, an embodiment of the present specification further provides an execution method of an external service, which is applied to a gateway, as shown in fig. 4, where fig. 4 is a schematic flow diagram of the execution method of the external service provided in the embodiment of the present specification, and specifically includes the following steps:

s401, receiving a service request, and determining a function node execution chain corresponding to the service request.

The user can send a request to the service system of the payment platform through the client. The service system may forward the request to the gateway so that the gateway obtains the service by executing the functional node execution chain.

For example, a user may operate a payment application client on the mobile device, and the application client may initiate an inquiry request to the accumulation fund service system, and then forward the request to the gateway by the accumulation fund service system, and communicate with external accumulation fund mechanisms in various levels of cities through executing a functional node chain, so as to obtain corresponding user accumulation fund information, and return the corresponding user accumulation fund information to be finally displayed to the user.

After receiving the service request, the gateway may query the database for a function node execution chain pre-stored by the access party obtaining the external service.

And S403, loading the function node execution chain.

S405, executing the function node execution chain according to the request parameter in the service request, and generating a service result.

The gateway may instantiate each function node in the function node execution chain as an executable object and execute it in sequence based on parameters included in the service request (e.g., the user's identity, user-entered query parameters, etc.)

S407, the service result is sent to the service request initiator.

Fig. 5 is a logic diagram illustrating a method for executing a accumulation fund query service according to an embodiment of the present disclosure. In the schematic diagram, the gateway performs query and communication based on the pre-stored function node execution chain, and returns the query result to the accumulation fund service system, so that the accumulation fund service system assembles the query result and sends the query result to the client of the user for display. In the process, the function node execution chain is generated by pre-configuration based on the mode of the first aspect, and codes do not need to be written in the configuration and execution processes, so that more convenient service access is realized.

In a third aspect, corresponding to the first aspect, an embodiment of the present specification further provides an access device for an external service, as shown in fig. 6, where fig. 6 is a schematic structural diagram of the access device for an external service provided by the embodiment of the present specification, and includes:

Optionally, the apparatus further includes a simulation module 607, which displays a simulation execution result of the function node execution chain, so that the service access party adjusts the function node execution chain according to the simulation execution result.

Optionally, the presentation module 601 obtains style information of the functional node; and rendering and displaying the functional nodes according to the style information.

In a fourth aspect, corresponding to the second aspect, an embodiment of the present specification further provides an external service execution apparatus, as shown in fig. 7, where fig. 7 is a schematic structural diagram of the external service execution apparatus provided in the embodiment of the present specification, and includes:

a receiving module 701, configured to receive a service request, and determine a function node execution chain corresponding to the service request;

the execution module 705 executes the function node execution chain according to the request parameter in the service request to generate a service result;

the second sending module 707 sends the service result to the service request initiator.

In a fifth aspect, embodiments of the present specification further provide an electronic device. Fig. 8 is a schematic structural diagram of an electronic device provided in an embodiment of the present specification, where the electronic device includes:

at least one processor; and the number of the first and second groups,

a memory communicatively coupled to the at least one processor; wherein the content of the first and second substances,

the memory stores instructions executable by the at least one processor to enable the at least one processor to perform a method according to the first or second aspect.

In a sixth aspect, embodiments of the present specification further provide a non-volatile computer storage medium storing computer-executable instructions that, when read by a computer, cause the one or more processors to perform the method according to the first aspect or the second aspect.

In the 90's of the 20 th century, improvements to a technology could clearly distinguish between improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements to 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: the ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.

It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in the process, method, article, or apparatus that comprises the element.
