Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be obtained by a person skilled in the art without making creative efforts based on the embodiments of the present disclosure, belong to the protection scope of the embodiments of the present disclosure.
The service filtering method, apparatus, electronic device and storage medium provided by the present disclosure are described below with reference to fig. 1 to 5.
Fig. 1 is a flowchart of a service filtering method provided by the present disclosure, and as shown in fig. 1, the service filtering method provided by the present disclosure includes:
step 101, calling a first service combination according to the received first command and the information of the first user.
In this embodiment, the first command is a command sent by the first service system to the second service system, and the first user is a user of the second service system. For example, if the first command is a fund operation command sent by the asset securitization business system to the fund management system, the first service system is the asset securitization business system, and the second service system is the fund management system.
The service filtering method provided by this embodiment is applied to the second service system, which is also referred to as the ground in this embodiment. Correspondingly, the first service system is referred to as a cloud in this embodiment.
The first service combination includes a plurality of services having a preset execution order. For example, the first combination of services may include, in order, a decryption service, a format conversion service, and a funding service. The services are used for verifying the first command and executing the first command after the first command is verified. The first service combination may be a directed linked list formed by the services, or may be an array. In this embodiment, the specific form of the first service combination is not limited.
The number of services included in the first service combination, the content of the included services and the first command are related to the information of the first user.
The architecture of the second service system supports one instance serving multiple users, and the system gives the users the ability to make partial customizations to the system, such as customizing user interface colors or customizing business rules. Therefore, in the second service system, the business rules corresponding to different users may be different. Since the business rules may affect the services in the first service combination, the number of services included in the first service combination, and the content of the included services are related to the information of the first user. The information of the first user may be identification Information (ID) of the first user, user type information (e.g., corporate user, individual user) of the first user, and the like.
And the service in the first service combination is used for verifying the first command and executing the first command after the verification is passed. If the content of the first command is different, there may be a difference in the service used to authenticate and execute the first command. For example, for a command with a high security requirement, security verification is required before execution, and for a command with a low security requirement, security verification may be omitted before execution. Therefore, the number of services included in the first service combination, and the content of the included services are related to the first command.
For the above reasons, in this step, it is necessary to determine the first service combination according to the first command and the information of the first user and invoke the first service combination.
For example, after receiving the command c, the user a invokes a first service combination including a replacement service, a recurrent purchase service, and a settlement service; after receiving the command c, the user b invokes a first service combination including a recurring purchase service and an assignment service.
Step 102, selecting services from the first service combination according to the execution sequence, determining whether the first command meets a preset condition corresponding to the selected services according to the selected services, and intercepting the first command when the first command does not meet the preset condition.
In a previous step, a first combination of services has been determined and invoked according to the first command and the information of the first user. In this step, each service in the first service combination needs to be adopted to verify and execute the first command.
Since in the first service combination the execution order between the included services has been defined. Therefore, in this embodiment, the services can be sequentially selected according to the execution order, and the first command can be verified and executed by using the selected services.
For example, the first command is a fund operation command encrypted by an encryption algorithm a, and the first service combination includes a decryption service, a format conversion service, and a fund operation service. In the above service, the decryption service and the format conversion service are used for verifying the first command, and the fund operation service is used for executing the first command. The first command is verified before the first command is executed. When the first command is verified, firstly, a decryption service is selected, the decryption service verifies whether the first command meets a decryption algorithm A '(the decryption algorithm A' is a decryption algorithm corresponding to the encryption algorithm A), if the first command meets the preset condition corresponding to the decryption service, the first command is proved to meet the preset condition (assuming that the decryption service only performs ciphertext decryption operation), and the format conversion service is continuously selected to verify the first command; if not, the first command is proved not to meet the preset condition corresponding to the decryption service, and the first command is intercepted, namely the verification process of the first command is terminated. The authentication process of the format conversion service for the first command is also similar and therefore not repeated here. After the first command is verified, the fund operation service executes the first command (fund operation command), and when the first command is executed, it is also required to determine whether the first command meets a preset condition corresponding to the fund operation service, and if not, the first command needs to be intercepted, that is, the execution process of the first command is terminated.
In this embodiment, if any one of the first combination of services fails to determine (verify or execute) that the first command passes, the first command is intercepted. After the first command is intercepted, the second service system will not execute the first command. This strongly guarantees the accuracy with which the first command is executed.
It should be noted that a service may include a plurality of atomic operations related to authentication, and if a first command fails to pass any of the plurality of atomic operations, the first command is not determined to pass by the service.
The service filtering method provided by the disclosure calls the corresponding service combination according to the received command and the user information of the service system, the command is verified and executed by the service in the service combination, and only the command passing the verification can be executed, so that the accuracy and the safety of command execution are ensured.
Based on any one of the above embodiments, in this embodiment, the method further includes:
and under the condition that the first command meets the preset condition, selecting the next service from the first service combination according to the execution sequence, and re-executing the step of determining whether the first command meets the preset condition corresponding to the selected service according to the selected service until all the services in the first service combination are determined to pass the first command.
In the previous embodiment, a case was described where the first command failed to be passed by a certain service in the first service combination, resulting in the first command being intercepted.
In this embodiment, when the first command is determined to pass through by a certain service in the first service combination, a next service is selected from the first service combination according to the execution sequence, and then the first command is continuously verified or executed by the selected new service. And the first command completes the process of service filtering only after all the services in the first service combination are determined to pass the first command.
The service filtering method provided by the disclosure calls the corresponding service combination according to the received command and the user information of the service system, the command is verified and executed by the service in the service combination, and only the command passing the verification can be executed, so that the accuracy and the safety of command execution are ensured.
Based on any of the above embodiments, in this embodiment, the first service combination is a first service chain; wherein the content of the first and second substances,
the first service chain comprises a plurality of master nodes, and the first master node corresponds to a first service; wherein the first host node is one of the host nodes, and the first service is one of the first service combination;
the first master node includes a child node corresponding to one atomic operation in the first service.
In the previous embodiments, the composition and role of the first service combination are explained. In this embodiment, an implementation manner of the first service combination is further described.
In this embodiment, the first service combination is a first service chain. The first service chain comprises a single chain table, the single chain table comprises a plurality of main nodes, and one main node in the main nodes corresponds to one service in the first service combination. The run of the one-way linked list in the first service chain describes the execution order among the plurality of primary nodes.
For example, the first service combination includes, in order, a decryption service, a format conversion service, and a funding service. The corresponding first service chain is a single linked list comprising three primary nodes, wherein the first primary node represents a decryption service, the second primary node represents a format conversion service, and the third primary node represents a fund operation service.
The first chain of service also includes a doubly linked list. A doubly linked list may be included under the primary node, the doubly linked list including one or more child nodes, each child node corresponding to an atomic operation in the service. For example, a host node represents a decryption operation, which may be further subdivided into multiple atomic operations, such as lease verification, ciphertext decryption, and signature verification. A doubly linked list may be set under the master node, where the doubly linked list includes three child nodes, where the first child node represents the lease verification, the second child node represents the ciphertext decryption, and the third child node represents the signature verification. The first direction in the doubly linked list describes an execution order among the plurality of child nodes, and the second direction in the doubly linked list describes a return order after the execution of the plurality of child nodes is finished.
Fig. 2 is a schematic diagram of a first service chain involved in the service filtering method provided by the present disclosure in an embodiment, and as shown in fig. 2, the first service chain includes a single-direction linked list, where the single-direction linked list includes a1- > a2- > A3- > EndPoint, where a1, a2, and A3 are master nodes, and EndPoint is an end node. The main node A1 is connected with a doubly linked list b1- > b2- > b3, wherein b1, b2 and b3 are all child nodes in the doubly linked list; the main node A2 is connected with a doubly linked list c1, wherein c1 is the child node in the doubly linked list; master node A3 has a doubly linked list d1- > d2, where d1 and d2 are the children of the doubly linked list.
The service filtering method provided by the disclosure represents the service combination in a directed chain table mode, represents the service in the service combination by using the main node, represents the atomic operation in the service by using the sub-node, and can realize the verification and execution of the command by using the directed chain table.
Based on any of the foregoing embodiments, in this embodiment, selecting services from the first service combination according to the execution order, and determining whether the first command satisfies a preset condition corresponding to the selected service according to the selected services includes:
and selecting a main node which does not verify the first command from the first service chain according to the trend of the first service chain, and determining whether the first command meets a preset condition or not by the selected main node or a sub-node contained in the selected main node.
In the previous description, the structure of the first service chain has been explained. In this embodiment, when the first command is subjected to service filtering, according to the trend of the first service chain, the first command first reaches a first main node in a single direction chain table, and a first child node is selected from a double direction chain table under the main node; taking the first child node as a current child node, determining whether the first command meets corresponding preset conditions or not by the current child node, if so, judging whether a next child node exists or not, if so, taking the next child node as the current child node, and then re-executing the step of calling the current child node to determine whether the first command meets the corresponding preset conditions or not; and if the next child node does not exist, returning the main node where the current child node is located. And if the first command does not meet the preset condition, intercepting the first command, namely ending the process of performing service filtering on the first command.
If there are multiple master nodes in the single-direction chain table, referring to the above description, each master node (if the service corresponding to the master node has only one atomic operation) or a child node under the master node (if the service corresponding to the master node has more than one atomic operation) is used to determine whether the preset condition is satisfied for the first command. If the first command can pass the filtering of all the services in the first service chain, the first command is qualified and can be executed subsequently. If the first command is intercepted by any main node or sub-node under the main node in the first service chain, the failure of the process of performing service filtering on the first command is shown, and the first command is not executed any more subsequently.
It should be noted that the first service chain is implemented by using a Filter interceptor, and therefore, the master node and the child node in the first service chain have the capability of intercepting the first command.
The service filtering method provided by the disclosure realizes the verification and execution of the command through the directed linked list, and only the command passing the verification can be executed, thereby ensuring the accuracy and the safety of the command execution.
Based on any one of the above embodiments, in this embodiment, the first service combination includes a third service; wherein the third service is a service provided by a third service system.
In the foregoing embodiment, it has been mentioned that the service filtering method provided by the present disclosure relates to a first service system and a second service system. The first service system is a service system which issues a first command; the second service system is a system that receives the first command and performs service filtering on the first command. For example, the first service system is an asset securitization business system and the second service system is a fund management system.
In this embodiment, the service included in the first service combination called in the second service system is not limited to the service provided by the second service system, and may be a third service system different from the first service system and the second service system. For example, during the process of securitization of assets, a third party assessment of the assets is required, and therefore, the assessment service provided by the third party service system can be included in the first service portfolio.
The service filtering method provided by the disclosure allows the services in the service combination to be the services provided by the third party, so that the command verification is more flexible and diversified.
Based on any one of the foregoing embodiments, in this embodiment, the invoking the first service combination according to the received first command and the information of the first user includes:
acquiring configuration information according to the received first command and the information of the first user;
determining a plurality of services and an execution sequence among the plurality of services according to the configuration information;
determining a first service combination according to the plurality of services and an execution order among the plurality of services;
invoking the first service combination.
In this embodiment, a specific implementation process for invoking the first service combination according to the first command and the information of the first user is described.
After the second service system receives the first command sent by the first service system, the content contained in the first command can be determined. Information of a first user currently using the second service system may also be determined.
After determining the first command and the information of the first user, the configuration information can be obtained accordingly. The configuration information is used for describing a service required for verifying and executing the first command and an execution sequence between the required services in the case where the user of the second service system is the first user. The configuration information may be pre-stored in a database, and the database also stores a mapping relationship between the configuration information and the first command and the first user.
After the configuration information is obtained, according to the content included in the configuration information, the plurality of services and the execution sequence among the plurality of services can be determined, and then the first service combination is obtained. If the first service combination is a first service chain, when the first service chain is generated, one service can be corresponding to one main node, and then a plurality of main nodes are connected in series to form a single linked list according to the execution sequence among a plurality of services; then, according to the atomic operations contained in each service, child nodes are mounted under a main node, one child node corresponds to one atomic operation in the service, and the sequence of the atomic operations in the service corresponds to the sequence of a plurality of child nodes under the same main node.
After determining the first combination of services, the first combination of services may then be invoked.
The service filtering method provided by the disclosure determines the configuration information through the received command and the information of the user, determines the service combination according to the configuration information, realizes flexible configuration of the service combination, and meets the requirements that different asset parties can need various services and can configure different services in an asset securitization application scene.
For ease of understanding, the service filtering method provided by the present disclosure is further described below with reference to a specific example.
In one embodiment, an asset securitization business system (cloud) issues a command to a fund management system (ground) to cyclically purchase 1 billion assets. After receiving the command, the fund management system executes the following steps:
step S1, after receiving the command, the fund management system invokes the service chain corresponding to the command. Fig. 3 is a schematic diagram of a service chain involved in another embodiment of a service filtering method provided by the present disclosure.
Step S2, the first master node service _ chain _1 in the service chain intercepts the command, and performs a decryption operation on the command. The first master node service _ chain _1 has three child nodes sub _ chain _1, sub _ chain _2 and sub _ chain _3 mounted thereon, which respectively correspond to three atomic operations of the decryption operation: and renting and verifying operation, ciphertext decryption operation and signature verification operation. Therefore, when the command is decrypted, the lease-back verification operation, the ciphertext decryption operation and the signature verification operation need to be executed in sequence, and the decryption operation of the command is completed only if the atomic operations of the three decryption operations are passed. Once the atomic operation of any one of the decryption operations fails, the command is not decrypted successfully, the command is discarded, and other services on the service chain are not called to process the command.
And if the atomic operations of the three decryption operations are passed when the command is decrypted, returning to the main node service _ chain _1 to execute the next main node.
Step S3, the second master node service _ chain _2 in the service chain intercepts the command, and performs a format conversion operation on the command.
Because different asset parties have differences in the details of fund management, command formats corresponding to different users in the fund management system may also differ. This makes commands issued by the asset securitization business system difficult to directly identify by the funds management systems of different users. In view of the above, it is necessary to set a master node service _ chain _2 capable of performing a format conversion operation on a command in a service chain.
And the child node sub _ chain _1 mounted on the main node service _ chain _2 corresponds to format conversion operation and is used for carrying out format conversion on the command.
If the format conversion operation can be realized, returning to the main node service _ chain _2 to execute the next main node; if not, the command is discarded and no other services on the service chain are called to process the command.
And step S4, intercepting the command by a third main node service _ chain _3 in the service chain, and performing asset operation according to the command.
The first main node and the second main node in the service chain realize the verification of the command, and the third main node is used for executing the command, namely, carrying out asset operation according to the asset operation command. In this embodiment, the asset operation includes an asset cyclic purchase operation and an unqualified asset pool operation, and corresponds to two child nodes sub _ chain _1 and sub _ chain _2 under the host node service _ chain _3, respectively. After the two atomic operations in the asset operation are respectively executed according to the sequence, returning to the main node service _ chain _3 to execute the next main node; if either of the two atomic operations described above in the asset operation cannot be implemented, the command is discarded and no other service on the service chain is called to process the command.
Step S5, the current master node in the service chain is an end node EndPoint, and ends the service filtering of the command.
The service filtering apparatus provided by the embodiments of the present disclosure is described below, and the service filtering apparatus described below and the service filtering method described above may be referred to in correspondence with each other.
