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 reasonability of a service. The following are detailed below.
In order to better understand an information processing method, an information processing apparatus, 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 ranking 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. The endorsement node 102 is configured to receive an endorsement request from the client 101, verify whether the client 101 is a valid client, simulate a service corresponding to the service proposal if the client 101 is a valid client, and send a service request to the service system 103. And the service system 103 is configured to receive the service request from the node 102, verify whether the 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 the endorsement response to the client 101 according to the service response. The client 101 is further configured to determine whether to execute a service proposal according to the endorsement response and the endorsement policy, and generate a service according to the service proposal and the endorsement response and send the service to the sequencing node 104 when determining to execute the service proposal. And the sequencing node 104 is configured to receive the service from the client 101, sequence and package the service, and send the processed service to the accounting node 105. And the accounting node 105 is used for receiving the processed service from the sequencing node 104 and processing the processed service.
In order to better understand an information processing method, an information processing apparatus, 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 view 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. And after receiving the service request from the client, the endorsement node verifies the client, simulates a service proposal under the condition that 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 strategy, generate the service according to the service proposal and the endorsement response under the condition of determining to submit the service, and then submit the sequence to the sequencing node. And after receiving the sequencing from the client, the sequencing node sequentially sequences and packages the services, and then transmits the packaged services to the accounting node through block broadcasting. And after receiving the packaged service from the sequencing node, the accounting node divides the packaged service into individual services, processes the services and stores the processing results of the services. Only the endorsement node audits 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 present invention based on the network structure shown in fig. 1. The information processing method is described from the perspective of the client, endorsement node and business 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 side can send an endorsement request to the endorsement node, the endorsement request can carry a first identifier and a first parameter, the first identifier is an identifier of the intelligent contract, and the first parameter is a parameter required by the intelligent contract. The service request can be generated according to a service proposal created by the client, or can be generated according to service proposals from other clients.
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. And the service system verifies whether the service corresponding to the first identifier and/or the first parameter is a legal service.
After receiving the service request from the endorsement node, the service system may verify whether the service corresponding to the first identifier and/or the first parameter is a legitimate service.
304. And the service system sends a service response to the endorsement node according to the verification result.
After the service system verifies that the first identifier and/or the first parameter corresponds to the service, the service system can send a service response to the endorsement node according to the verification result. And under the condition that the service response is sent to the endorsement node only if the verification is successful, namely the service corresponding to the first identifier and/or the first parameter is legal, the service response is used for indicating that the service corresponding to the first identifier and/or the first parameter is legal. And under the condition that the service response needs to be returned to the endorsement node regardless of the verification result, the service response carrying the verification result can 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 the service response is sent to the endorsement node only if the service corresponding to the first identifier and/or the first parameter is legal service, the endorsement node indicates that the service corresponding to the first identifier and/or the first parameter is legal service as long as the endorsement node receives the service response. And in the case that the endorsement response is returned to the client only if the endorsement is successful, sending the endorsement response to the client once the service response from the service system is received. Under the condition that the endorsement response needs to be returned to the client side regardless of the endorsement result, the endorsement response carrying successful endorsement can be sent to the endorsement node.
And under the condition that the 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 authentication result can be identified first, the endorsement response is sent to the client when the authentication result is identified as successful, and the endorsement response is not sent to the client when the authentication result is identified as failed, namely the service corresponding to the first identifier and/or the first parameter is illegal. Under the condition that the endorsement response needs to be returned to the client side regardless of the endorsement result, the endorsement result can be generated according to the verification result, the endorsement success can be generated under the condition that the verification result is successful, the endorsement failure can be generated under the condition that the verification result is failed, and then the endorsement response carrying the endorsement result can be sent to the client side.
The processing procedure after the endorsement node receives the endorsement acknowledgement is the same as the description corresponding to fig. 2, and the detailed description may refer to the description corresponding to fig. 2.
The client and the endorsement node belong to the same block chain.
In the service processing method described in fig. 3, since the endorsement response is sent to the client according to the service response, it can be seen that, more than the endorsement node performs the audit on the service corresponding to the endorsement request, the external service system also performs the audit on the service corresponding to the endorsement request, thereby increasing the audit strength of the service, and improving the rationality of the service.
Referring to fig. 4, fig. 4 is a schematic flow chart of another information processing method according to an embodiment of the present 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 sequencing 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 side can send an endorsement request to the endorsement node, the endorsement request can carry a first identifier, a second identifier and a first parameter, the first identifier is an identifier of the intelligent contract, the second identifier is an identifier of the client side, and the first parameter is a parameter required by the intelligent contract. The service request can be generated according to a service proposal created by the client, or can be generated according to service proposals from other clients.
402. And the endorsement node verifies whether the client corresponding to the second identification is 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 valid client, and may perform step 403 and/or step 404 if it is verified that the client corresponding to the second identifier is a valid client. And under the condition that the client corresponding to the second identifier is an illegal client, ending the process, namely not executing the subsequent process, and sending information for indicating that the client is the illegal client to the client.
403. And the endorsement node simulates the first identifier and/or the service corresponding to the first parameter by using the first parameter and the intelligent contract corresponding to the first identifier.
And under the condition that the endorsement node verifies that the client corresponding to the second identifier is a legal client, simulating the service corresponding to the first identifier and/or the first parameter 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.
The endorsement node may send a service request to the service system when the endorsement node verifies that the client corresponding to the second identifier is a valid client, or after the endorsement node uses the intelligent contract corresponding to the first parameter and the first identifier to simulate the service corresponding to the first identifier and/or the first parameter. 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 valid client and then sends the service request. And under the condition that the service request is sent after the endorsement node simulates the first identifier and/or the service corresponding to the first parameter by using the intelligent contract corresponding to the first parameter and the first identifier, the service request can carry the simulation result besides the first identifier and/or the first parameter. Step 403 may be executed before step 404, may be executed after step 404, or may be executed simultaneously with step 404.
405. And the service system verifies whether the service corresponding to the first identifier and/or the first parameter is a legal service.
After receiving the service request from the endorsement node, the service system may verify whether the service corresponding to the first identifier and/or the first parameter is a legitimate service. Under the condition that the service request carries the simulation result, the stored storage result of the service corresponding to the first identifier and/or the first singular number can be obtained, and whether the service is a legal service or not can be judged according to the simulation result and the storage result, or whether the simulation result is matched with the storage result or not can be judged. And under the condition that the matching is judged, determining that the service is legal service, and under the condition that the mismatching is judged, determining that the service is illegal service. The matching may be the same, or the similarity or the association is greater than a threshold, or the stored result includes a simulation result, or the stored result may follow the same rule, or may represent other situations that can represent matching, which is not limited herein.
Under the condition that the service request does not carry a 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, obtain the stored storage result of the service corresponding to the first identifier and/or the first singular number, and then judge whether the service is legal or not according to the simulation result and the storage result.
406. And the service system sends a service response to the endorsement node according to the verification result.
Step 406 is the same as step 304, and the detailed description may refer to step 304, which is not repeated herein.
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 may refer to step 305, which is not described herein again. In addition, the endorsement response may carry simulation results.
In one embodiment, the endorsement node may send an endorsement acknowledgement to the client based on the service acknowledgement and the simulation result.
408. The client indicates to the sequencing node a sequencing request for sequencing 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 may refer to the related description, which is not described herein again.
409. The sequencing node sends an accounting request to the accounting node for 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 described herein again.
410. And the accounting node processes the service.
Step 410 is the same as the processing procedure after the accounting node corresponding to fig. 2 receives the packaged service from the sequencing node, and the detailed description may refer to the related description, which is not described herein again.
The client, the endorsement node, the sequencing node and the accounting node belong to the same block chain.
In the service processing method described in fig. 4, since the endorsement response is sent to the client according to the service response, it can be seen that, more than the endorsement node performs the audit on the service corresponding to the endorsement request, the external service system also performs the audit on the service corresponding to the endorsement request, thereby increasing the audit strength of the service, and improving the rationality of the service.
For example, a certain e-commerce platform a and an express company B cooperate, a entrusts B to help to send an express, and the express fee is settled to B monthly. Under the scene, both sides need to carry out respective accounting, and account checking and settlement are carried out at the end of the month. If A and B are accounted by block chains, after each A order and B send an express, one party must write accounting information into the block chain, and the accounting information needs to be endorsed or confirmed as soon as possible by the other party. Because the account information is a new piece of account information, the user can not judge whether to endorse the account information according to the linked information during endorsement, and how to evaluate the correctness of the account information can only be according to an IT system outside the block chain. In more detail, suppose that 24 days 6 and 6 in 2019, A orders B to send a package, B takes the package, then weighing and evaluating the package, and printing an express receipt to A. B (or A) then initiates a proposal aiming at the package, and the proposal content is as follows: 24 days 6 and 24 months 2019, A orders B to send a package, the number of an express bill is xxxx, the weight is 0.9kg, the content is ooo, and the express fee is 12 yuan. "this proposal needs to be written on the chain after the endorsements of A, B parties, so that the settlement can be carried out by both parties at the end of the month, and the endorsement condition is that both parties A and B agree. At this time, since the information systems of the A and B parties are not interconnected, the information cannot be endorsed in time, and even the express bill number and the amount of money may need to be checked manually for confirmation. In this scenario, it is not appropriate to endorse only according to the information that is linked up, and the root cause is that the courier tickets are independent from each other and are not related from top to bottom. If the scheme of the invention is used, after proper configuration, the endorsement nodes of the two parties can automatically access respective information systems or even databases when the endorsement is needed, check and endorse the express bill number xxxx and the amount of money thereof, and finally automatically complete the chaining and the accounting operation, so that the two parties use the block chains to perform consensus and accounting, and the accounting on each chain is obtained and cannot be repudiated. If the endorsement node accesses the service side information system, it finds that the express delivery order number does not exist, or the express delivery order number is not matched with the money amount, the proposal can be marked as manual processing or endorsement refusing, the disputed account information cannot be linked up immediately, and a service party can intervene in the processing manually.
Referring to fig. 5, fig. 5 is a schematic flow chart illustrating another information processing method according to an embodiment of the present invention. The information processing method is described from a client, an endorsement node, a service system, a sequencing 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 may refer to step 401, which is not described herein again.
502. And the endorsement node verifies whether the client corresponding to the second identification is 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 valid client, and may perform step 503 if it is verified that the client corresponding to the second identifier is a valid client. And under the condition that the client corresponding to the second identifier is an illegal client, ending the process, namely not executing the subsequent process, and sending information for indicating that the client is the illegal client to the client.
503. And the endorsement node simulates the first identifier and/or the service corresponding to the first parameter by using the first parameter and the intelligent contract corresponding to the first identifier.
Step 503 is the same as step 403, and the detailed description may refer to step 403, which is not described herein again.
504. And the endorsement node sends an endorsement response to the client.
And after the endorsement node simulates the first identifier and/or the service corresponding to the first parameter by using the first parameter and the intelligent contract corresponding to the first identifier, a simulation result can be obtained. And under the condition that the endorsement response is returned to the client only after the endorsement is successful, judging the reasonability of the simulation result, sending the endorsement response to the client under the condition that the simulation result is judged to be reasonable, and under the condition that the simulation result is judged to be unreasonable, not sending the endorsement response to the client. Under the condition that the 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 and endorsement failure. For example, in the case where the service is a transfer service and the simulation result is a negative amount of money remaining after the transfer, the simulation result is not reasonable.
505. The client indicates to the sequencing node a sequencing request for sequencing the service.
Step 505 is the same as step 408, and the detailed description may refer to the related description, which is not repeated herein.
506. The sequencing node sends an accounting request to the accounting node for 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 herein.
507. And the accounting node processes the service.
Step 507 is the same as step 410, and the detailed description may refer to the related description, which is not repeated herein.
508. And the service system acquires the service processing result from the accounting node.
The service system can acquire the processing result of the service from the accounting node in real time, periodically or under the condition that the processing result of the service is detected.
509. The service system verifies the validity of the service according to the processing result and the stored storage result, and if the validity is verified, step 510 is executed.
After the service system obtains the processing result of the service from the accounting node, the validity of the service may be verified according to the processing result of the service and the stored result corresponding to the stored service, and the verification method may be the same as that in step 405. In case the traffic is verified to be illegal, step 510 is performed. And under the condition that the service is verified to be legal, the service is not processed.
510. And the service system sends indication information for indicating that the service is illegal to the accounting node.
After receiving the indication from the service system, the accounting node may cancel the processing of the service and delete the storage of the service.
The client, the endorsement node, the sequencing node and the accounting node belong to the same block chain.
In the service processing method described in fig. 5, since the external service system verifies the processing result of the service, it can be seen that, the external service system also verifies the processing result of the service, so that the service corresponding to the endorsement request is verified by more than the endorsement node, and the service processing result is also verified by the external service system, thereby increasing the verification strength of the service, and improving the rationality of the service. Although the auditing strength of the service can be increased in fig. 5 compared with fig. 4, the auditing of the service system is performed last, which takes a long time, and thus the information processing efficiency is reduced.
