Detailed Description
The embodiment of the invention discloses an information processing method, an information processing device and a computer readable storage medium, which are used for improving the rationality of business. The following will describe in detail.
In order to better understand an information processing method, an information processing device and a computer readable storage medium disclosed in the embodiments of the present invention, a network architecture used in the embodiments of the present invention is described below. Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the present invention. As shown in fig. 1, the network architecture may include a client 101, an endorsement node 102, a business system 103, a sorting node 104, and an accounting node 105. The client 101 is configured to generate a service proposal according to an operation of a user, and send an endorsement request to the endorsement node 102 according to the service proposal. An endorsement node 102, configured to receive an endorsement request from the client 101, verify whether the client 101 is a legal client, simulate a service corresponding to the service proposal if the client 101 is verified to be a legal client, and send a service request to the service system 103. The service system 103 is configured to receive a service request from the client 102, verify whether a service corresponding to the service proposal is a legal service according to the service request, and send an endorsement response to the endorsement node 102 according to the verification result. The endorsement node 102 is further configured to receive a service response from the service system 103, and send an endorsement response to the client 101 according to the service response. The client 101 is further configured to determine whether to execute the service proposal according to the endorsement response and the endorsement policy, and generate a service according to the service proposal and the endorsement response when determining to execute the service proposal, and send the service to the ordering node 104. The ordering node 104 is configured to receive the service from the client 101, perform ordering and packaging processing on the service, and send the processed service to the accounting node 105. And a billing node 105 for receiving the processed traffic from the sorting node 104 and processing the processed traffic.
In order to better understand an information processing method, an information processing device and a computer readable storage medium disclosed in the embodiments of the present invention, an application scenario used in the embodiments of the present invention is described below. Referring to fig. 2, fig. 2 is a schematic diagram of a service processing according to an embodiment of the present invention. As shown in fig. 2, the endorsement node creates a service proposal and sends a service request to the endorsement node. After receiving the service request from the client, the endorsement node verifies the client, simulates the service proposal if the client is a legal client, and then sends an endorsement response to the client. After receiving the endorsement response from the endorsement node, the client can determine whether to submit the service according to the endorsement response and the endorsement policy, and under the condition of determining to submit the service, the client generates the service according to the service proposal and the endorsement response, and then submits the ordering to the ordering node. After receiving the ordering from the client, the ordering node sequentially performs ordering and packaging processing on the service, and then sends the packaged service to the accounting node through block broadcasting. After receiving the packed services from the ordering node, the billing node splits the packed services into individual services, processes the services, and stores the processing results of the services. Only the endorsement node performs auditing on the service proposal corresponding to the endorsement request, and the service proposal corresponding to the endorsement request cannot be audited based on external conditions, so that the auditing strength of the service is reduced, and the rationality of the service is reduced.
Referring to fig. 3, fig. 3 is a schematic flow chart of an information processing method according to an embodiment of the invention. The information processing method is described from the angles of a client, an endorsement node and a service system. As shown in fig. 3, the information processing method may include the following steps.
301. And the client sends an endorsement request to the endorsement node.
The client may send an endorsement request to the endorsement node, where the endorsement request may carry a first identifier and a first parameter, the first identifier is an identifier of the smart contract, and the first parameter is a parameter required by the smart contract. The service request may be generated according to a service proposal created by the client, or may be generated according to a service proposal from another client.
302. And the endorsement node sends a service request to the service system.
After receiving the endorsement request from the client, the endorsement node may send a service request to the service system, where the service request may carry the first identifier and/or the first parameter.
303. The service system verifies whether the service corresponding to the first identifier and/or the first parameter is legal service or not.
After the service system receives the service request from the endorsement node, it can verify whether the service corresponding to the first identifier and/or the first parameter is legal service.
304. And the service system sends service response to the endorsement node according to the verification result.
After the service system verifies the service corresponding to the first identifier and/or the first parameter, a service response can be sent to the endorsement node according to the verification result. And under the condition that only the verification is successful, namely the service corresponding to the first identifier and/or the first parameter is legal service, sending a service response to the endorsement node, wherein the service response is used for indicating that the service corresponding to the first identifier and/or the first parameter is legal service. In the case that a service response needs to be returned to the endorsement node regardless of the verification result, the service response carrying the verification result may be sent to the endorsement node.
305. And the endorsement node sends an endorsement response to the client according to the service response.
After receiving the service response from the service system, the endorsement node may send an endorsement response to the client according to the service response. And under the condition that only the service corresponding to the first identifier and/or the first parameter is legal service, the service response is sent to the endorsement node, and the endorsement node only receives the service response to indicate that the service corresponding to the first identifier and/or the first parameter is legal service. In the case that an endorsement response is returned to the client only if the endorsement is successful, the endorsement response is sent to the client upon receiving a service response from the service system. In the case that an endorsement response needs to be returned to the client regardless of the endorsement result, an endorsement response carrying the endorsement success can be sent to the endorsement node.
In the case that a service response needs to be returned to the endorsement node regardless of the verification result, the service response carries the verification result. When the endorsement response is returned to the client only after the endorsement is successful, the verification result can be firstly identified, the endorsement response is sent to the client when the verification result is identified as the verification success, and the endorsement response is not sent to the client when the verification result is identified as the verification failure, namely, the condition that the service corresponding to the first identifier and/or the first parameter is illegal service. In the case that an endorsement response needs to be returned to the client regardless of the endorsement result, the endorsement result can be generated according to the verification result, the endorsement can be generated successfully when the verification result is successful, the endorsement failure can be generated when the verification result is failed, and then the endorsement response carrying the endorsement result can be sent to the client.
The processing procedure after the endorsement node receives the endorsement response is the same as that of the corresponding description of fig. 2, and the detailed description can refer to the corresponding description of fig. 2.
Wherein the client and the endorsement node belong to the same blockchain.
In the service processing method described in fig. 3, since an endorsement response is sent to the client according to the service response, it can be seen that not only the endorsement node performs an audit on the service corresponding to the endorsement request, but also the external service system performs an audit on the service corresponding to the endorsement request, so that the audit intensity of the service is increased, and the rationality of the service can be improved.
Referring to fig. 4, fig. 4 is a flow chart of another information processing method according to an embodiment of the invention based on the network architecture shown in fig. 1. The information processing method is described from a client, an endorsement node, a service system, a sorting node and an accounting node. As shown in fig. 4, the information processing method may include the following steps.
401. And the client sends an endorsement request to the endorsement node.
The client may send an endorsement request to the endorsement node, where the endorsement request may carry a first identifier, a second identifier, and a first parameter, where the first identifier is an identifier of the intelligent contract, the second identifier is an identifier of the client, and the first parameter is a parameter required by the intelligent contract. The service request may be generated according to a service proposal created by the client, or may be generated according to a service proposal from another client.
402. The endorsement node verifies whether the second identifier corresponds to the client as a legal client.
After receiving the endorsement request from the client, the endorsement node may verify whether the client corresponding to the second identifier is a legal client, and if it is verified that the client corresponding to the second identifier is a legal client, step 403 and/or step 404 may be executed. And under the condition that the client corresponding to the second identifier is verified to be the illegal client, the method can be ended, namely, the subsequent flow is not executed, and information for indicating that the client is the illegal client can be sent to the client.
403. And the endorsement node uses the first parameter and the intelligent contract corresponding to the first identifier to simulate the first identifier and/or the business corresponding to the first parameter.
And under the condition that the endorsement node verifies that the client corresponding to the second identifier is a legal client, the first identifier and/or the business corresponding to the first parameter can be simulated by using the first parameter and the intelligent contract corresponding to the first identifier.
404. And the endorsement node sends a service request to the service system.
And under the condition that the endorsement node verifies that the client corresponding to the second identifier is a legal client, or after the endorsement node uses the first parameter and the intelligent contract corresponding to the first identifier to simulate the first identifier and/or the service corresponding to the first parameter, the endorsement node can send a service request to the service system. The service request may carry the first identifier and/or the first parameter when the endorsement node verifies that the client corresponding to the second identifier is a legal client and sends the second identifier. In the case that the service request is sent after the endorsement node uses the first parameter and the intelligent contract corresponding to the first identifier to simulate the first identifier and/or the service corresponding to the first parameter, the service request may carry the simulation result in addition to the first identifier and/or the first parameter. Step 403 may be performed before step 404, after step 404, or simultaneously with step 404.
405. The service system verifies whether the service corresponding to the first identifier and/or the first parameter is legal service or not.
After the service system receives the service request from the endorsement node, it can verify whether the service corresponding to the first identifier and/or the first parameter is legal service. Under the condition that the service request carries the simulation result, the stored first identifier and/or the stored result of the service corresponding to the first singular number can be obtained, and whether the service is legal or not can be judged according to the simulation result and the stored result, and whether the simulation result is matched with the stored result or not can be judged. And determining the service as legal service when the matching is judged, and determining the service as illegal service when the matching is not judged. The matching may be the same, the similarity or the association degree is greater than a threshold, the stored result includes a simulation result, the same rule may be followed, or other cases where matching can be represented, which is not limited herein.
Under the condition that the service request does not carry the simulation result, the service system can simulate the service by using the intelligent contract corresponding to the first parameter and the first identifier to obtain the simulation result, acquire the stored first identifier and/or the stored result of the service corresponding to the first singular number, and then judge whether the service is legal or not according to the simulation result and the stored result.
406. And the service system sends service response to the endorsement node according to the verification result.
Step 406 is the same as step 304, and the detailed description will refer to step 304, which will not be repeated here.
407. And the endorsement node sends an endorsement response to the client according to the service response.
Step 407 is the same as step 305, and the detailed description will refer to step 305, which will not be repeated here. In addition, the endorsement response may carry the simulation results.
In one embodiment, the endorsement node may send an endorsement response to the client based on the service response and the simulation result.
408. The client indicates to the ordering node an ordering request for ordering the service.
Step 408 is the same as the processing procedure after the client corresponding to fig. 2 receives the endorsement response from the endorsement node, and the detailed description will refer to the related description, which is not repeated here.
409. The ordering node sends a billing request to the billing node indicating the processing of the service.
Step 409 is the same as the processing procedure after the sorting node corresponding to fig. 2 receives the sorting submitted from the client, and the detailed description may refer to the related description, which is not repeated here.
410. The accounting node processes the traffic.
Step 410 is the same as the processing procedure after the billing node corresponding to fig. 2 receives the packaged service from the sorting node, and the detailed description will refer to the related description and will not be repeated here.
Wherein the client, endorsement node, ordering node and billing node belong to the same blockchain.
In the service processing method described in fig. 4, since an endorsement response is sent to the client according to the service response, it can be seen that not only the endorsement node performs an audit on the service corresponding to the endorsement request, but also the external service system performs an audit on the service corresponding to the endorsement request, so that the audit intensity of the service is increased, and the rationality of the service can be improved.
For example, a certain e-commerce platform A cooperates with an express company B, the A entrusts the B to help send the express, and the expense of the express is settled to the B in months. In this scenario, both parties need to keep accounts of each other, and check out and settlement are performed at the end of the month. If a and B are billed by means of the blockchain, then after each time a delegate B sends an express, one of the parties must write accounting information into the blockchain, and at the same time, the piece of accounting information needs to be endorsed or confirmed as soon as possible by the other party. Because the system is a new piece of accounting information, whether the system needs to be endorsed or not can not be judged according to the information which is already uplink when endorsed, and how to evaluate the accuracy of the accounting information can only be according to an IT system outside the blockchain. More specifically, suppose that at 24 days 6.2019, A entrusts B to send a package, B takes the package, and then weighs and evaluates the package, and prints an express receipt to A. B (or A) then initiates a proposal for this package, the proposal content being: 24 days of 6 months of 2019, A entrusted with B sending a package, express bill number xxxx, weight of 0.9kg, content ooo and express fee 12 yuan. The proposal needs to be written into a chain after the endorsements of the A, B parties so as to settle accounts of the moon end parties, and the endorsement condition is that A and B agree. At this time, since the information systems of the two parties a and B are not interconnected, the information cannot be written back in time, or even the number and the amount of the express bill may need to be checked manually for confirmation. In this scenario, it is not appropriate to endorse only according to the information that has been linked, and the root cause is that the express sheets are independent from each other, and there is no up-down association. If the scheme of the invention is used, after proper configuration, the endorsement nodes of both sides can automatically access respective information systems or even databases when endorsements are needed, check and endorse the express single number xxxx and the amount thereof, and finally automatically complete the operations of linking and accounting, so that both sides can use block chains to carry out consensus and accounting, and each account on each chain can obtain the endorsements of both sides and cannot be repudiated. If the endorsement node accesses the service side information system, it is found that the express bill number does not exist, or the express bill number is not matched with the amount of money, the proposal can be marked as manual processing or endorsement, the contended accounting information is not immediately linked, and the service party can be manually involved in processing.
Referring to fig. 5, fig. 5 is a flowchart of another information processing method according to an embodiment of the invention. The information processing method is described from a client, an endorsement node, a service system, a sorting node and an accounting node. As shown in fig. 5, the information processing method may include the following steps.
501. And the client sends an endorsement request to the endorsement node.
Step 501 is the same as step 401, and the detailed description will refer to step 401, which is not repeated here.
502. The endorsement node verifies whether the second identifier corresponds to the client as a legal client.
After receiving the endorsement request from the client, the endorsement node may verify whether the client corresponding to the second identifier is a legitimate client, and if it is verified that the client corresponding to the second identifier is a legitimate client, step 503 may be executed. And under the condition that the client corresponding to the second identifier is verified to be the illegal client, the method can be ended, namely, the subsequent flow is not executed, and information for indicating that the client is the illegal client can be sent to the client.
503. And the endorsement node uses the first parameter and the intelligent contract corresponding to the first identifier to simulate the first identifier and/or the business corresponding to the first parameter.
Step 503 is the same as step 403, and the detailed description will refer to step 403, which will not be repeated here.
504. And the endorsement node sends an endorsement response to the client.
And after the endorsement node uses the first parameter and the intelligent contract corresponding to the first identifier to simulate the first identifier and/or the business corresponding to the first parameter, a simulation result can be obtained. When the endorsement response is returned to the client only if the endorsement is successful, the rationality of the simulation result can be judged first, the endorsement response is sent to the client when the simulation result is judged to be reasonable, and the endorsement response is not sent to the client when the simulation result is judged to be unreasonable. In the case that an endorsement response needs to be returned to the client regardless of the endorsement result, the endorsement result can be generated according to the simulation result, and then the endorsement response carrying the endorsement result is sent to the endorsement node. The endorsement result can be endorsement success or endorsement failure. For example, in the case where the service is a transfer service and the simulation result is that the amount remaining after transfer is negative, it is indicated that the simulation result is not reasonable.
505. The client indicates to the ordering node an ordering request for ordering the service.
Step 505 is the same as step 408, and the detailed description will refer to the related description, which is not repeated here.
506. The ordering node sends a billing request to the billing node indicating the processing of the service.
Step 506 is the same as step 409, and the detailed description may refer to the related description, which is not repeated here.
507. The accounting node processes the traffic.
Step 507 is the same as step 410, and the detailed description may refer to the related description, which is not repeated here.
508. The service system obtains the service processing result from the accounting node.
The service system may obtain the processing result of the service from the accounting node in real time, periodically or in case of detecting the processing result of the service.
509. The service system verifies the validity of the service according to the processing result and the stored storage result, and if the service system verifies that the service is illegal, step 510 is executed.
After the service system obtains the service processing result from the accounting node, the validity of the service may be verified according to the service processing result and the stored service corresponding storage result, and the verification method may be the same as step 405. In case that the service is verified as an illegal service, step 510 is performed. In the case that the service is verified to be a legal service, no processing may be performed.
510. The service system sends indication information for indicating that the service is illegal to the accounting node.
After receiving the indication information from the service system, the accounting node may cancel the processing of the service and delete the storage of the service.
Wherein the client, endorsement node, ordering node and billing node belong to the same blockchain.
