It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] The following is an explanation of the terms in the embodiments of the present disclosure:

[0031] Client, also known as user end, refers to the program that corresponds to the server and provides local services to customers.

[0032] The server side, also known as the server side, refers to a computer program or device that provides a certain service in a computer network.

[0033] The information processing method and device according to the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0034] Figure 1 is a flowchart of the information processing method of the first embodiment of the present disclosure, such as Figure 1 As shown, the method comprises the following steps:

[0035] In step S101, order information sent by a first terminal device is received, a QR code is generated based on an order identifier carried in the order information, and the QR code is sent to the first terminal device for display.

[0036] In an embodiment of the present application, the order information includes at least one or more of the following: order creation time, order status, payment information, target object information, product information, discount information, and order identification.

[0037] In some embodiments, a preset QR code generation tool can be called to convert the order identifier and generate a QR code; in some embodiments, pre-set field types can be obtained from the order information, such as the order identifier and payment information, and a preset QR code generation tool or interface can be called to convert the order identifier and payment information to generate a QR code.

[0038] In some implementations, in order to further improve data security, the order identifier carried in the order information may be encrypted, and then a QR code may be generated based on the encrypted order identifier.

[0039] Optionally, in the embodiment of the present disclosure, the first terminal device may be a client.

[0040] In step S102, at least one data block is generated according to the order information, the data block is stored in a target data node of the distributed storage system, and the single-level directory information of the distributed storage system is updated according to the target data node and the order identifier.

[0041] In some implementations, the order information and the QR code are converted based on a preset data format to create at least one data block.

[0042] In some implementations, the order information is converted based on a preset data format to create at least one data block.

[0043] In some implementations, the amount of data of each candidate data node in the distributed database is obtained, the candidate data nodes are sorted based on the amount of data, and a preset number of candidate data nodes with less data are determined from the candidate data nodes as target data nodes. For example, data blocks can be stored in one or more target data nodes of a distributed storage system.

[0044] In some embodiments, index information is obtained based on the target data node and the order identifier, for example, the order identifier is used as the index and the path or identifier of the target data center is used as the index value to obtain the index information, and the index information is updated to the single-level directory information.

[0045] In step S103, the QR code sent by the second terminal device is received, and the single-level directory information is queried based on the QR code to obtain the target data node associated with the QR code.

[0046] Optionally, the second terminal device may be a server.

[0047] For example, in the embodiment of the present disclosure, the second terminal device can scan the QR code displayed by the first terminal device, and then send the QR code to the payment system. The payment system receives the QR code sent by the second terminal device, obtains an index based on the QR code, queries the single-level directory information based on the index, and obtains the target data node associated with the QR code.

[0048] In some implementations, the QR code is encrypted information, and the QR code can be decrypted according to a preset decryption strategy, and then an index can be obtained based on the QR code.

[0049] If the target data node associated with the QR code is obtained, the system returns detailed information about the data block in the node (such as path, size, type, etc.). If the target data node associated with the QR code is not found, it will prompt that the target object target data node does not exist.

[0050] In step S104, a data block is read from the target data node, where the data block includes payment information of the order information for subsequent payment operations.

[0051] Optionally, the path for reading the data block can be obtained based on the single-level directory information, and then based on the path, the data block can be read from the target data node, thereby quickly locating and reading the relevant data to achieve rapid processing of payment data. The data block includes payment information of the order information, and the payment information can be verified for security, and subsequent payment operations can be performed after the verification is passed.

[0052] In the disclosed embodiment, at least one data block is generated according to the order information, the data block is stored in the target data node of the distributed storage system, and the single-level directory information of the distributed storage system is updated according to the target data node and the order identifier; the QR code sent by the second terminal device is received, and the single-level directory information is queried based on the QR code to obtain the target data node associated with the QR code; the data block is read from the target data node, and the data block includes the payment information of the order information for subsequent payment operations. By optimizing the data storage and query process of order QR code payment, combined with the efficient processing capabilities of single-level directory search and distributed redundant storage, efficient processing and storage of payment orders can be achieved, thereby speeding up the payment process, improving user experience, and providing efficient and secure payment solutions.

[0053] Figure 2 is a flowchart of a method for processing information according to a second embodiment of the present disclosure. Figure 2 As shown, the method comprises the following steps:

[0054] In step S201, order information sent by the first terminal device is received, a QR code is generated based on an order identifier carried in the order information, and is sent to the first terminal device for display.

[0055] In step S202, at least one data block is generated according to the order information, and the data block is stored in a target data node of the distributed storage system.

[0056] For the introduction of step S201 to step S202, reference may be made to the relevant contents in the above embodiment, which will not be repeated here.

[0057] In step S203, index information of the data block is generated according to the target data node and the order identifier.

[0058] In some implementations, the index information of the data block is generated using the order identifier as an index and the identifier and path of the target data node as an index value.

[0059] In some implementations, a hash calculation is performed based on the order identifier to obtain a hash value of the order identifier, and index information of the data block is generated using the hash value of the order identifier as an index and the identifier and path of the target data node as an index value.

[0060] In some embodiments, in order to generate the index information of the data block, data encryption, risk identification and access control can be used to ensure the security of the stored order QR code and its associated data. For example, the index and / or index value can be encrypted, and accordingly, when the data block is subsequently read based on the index and / or index value, it is first decrypted. For another example, the generation process and use process of the index information are monitored for risks, and the data reading or processing process is stopped when it is determined that there is a risk. For another example, the identification of the first terminal device and the second terminal device that can be allowed to access can be used to control access to the first terminal device and the second terminal device.

[0061] In step S204, the single-level directory information is stored in blocks, and the index range of each storage block is obtained.

[0062] In the disclosed embodiment, the global directory table included in the single-level directory information can be stored in blocks, each block containing a certain number of directory entries. For each storage block, its index range can be obtained through the start index and the end index.

[0063] In step S205, the target index range corresponding to the order identifier is determined.

[0064] In some implementations, when the order identifier is used as the index, the corresponding target index range may be determined based on the order identifier.

[0065] In some implementations, when the hash value of the order identifier is used as an index, a hash calculation is first performed based on the order identifier to obtain the hash value of the order identifier, and then the target index range corresponding to the order identifier is located through the hash value.

[0066] In step S206, the target storage block corresponding to the target index range is determined, and the index information is updated to the target storage block to update the single-level directory information.

[0067] In some implementations, there is a mapping relationship between the index range and the storage block. Based on the mapping relationship, the target storage block corresponding to the target index range can be determined, and then the index information can be updated to the target storage block to update the single-level directory information.

[0068] In step S207, the QR code sent by the second terminal device is received, and the single-level directory information is queried based on the QR code to obtain the target data node associated with the QR code.

[0069] In step S208, a data block is read from the target data node, the data block including payment information of the order information for subsequent payment operations.

[0070] For the introduction of steps S207 to S208, reference may be made to the relevant contents in the above embodiments, which will not be repeated here.

[0071] In an embodiment of the present disclosure, index information of the data block is generated according to the target data node and the order identifier, the single-level directory information is stored in blocks, the index range of each storage block is obtained, the target index range corresponding to the order identifier is determined, the target storage block corresponding to the target index range is determined, and the index information is updated to the target storage block to update the single-level directory information. The present disclosure can reduce data transmission and processing errors caused by network anomalies or data center anomalies, improve the flexibility of information processing, and improve the stability and availability of the system.

[0072] Figure 3 is a flowchart of a method for processing information according to a third embodiment of the present disclosure. Figure 3 As shown, the method comprises the following steps:

[0073] In step S301, order information sent by the first terminal device is received, a QR code is generated based on an order identifier carried in the order information, and the QR code is sent to the first terminal device for display.

[0074] In step S302, at least one data block is generated according to the order information, the data block is stored in a target data node of the distributed storage system, and the single-level directory information of the distributed storage system is updated according to the target data node and the order identifier.

[0075] In step S303, a QR code sent by the second terminal device is received.

[0076] For the introduction of steps S301 to S303, reference may be made to the relevant contents in the above embodiments, which will not be repeated here.

[0077] In step S304, the QR code is parsed to obtain the order identifier carried by the QR code.

[0078] Call the preset QR code processing tool to read and parse the QR code and extract the order ID.

[0079] In some implementations, the extracted data may be further processed or verified according to a specific order identification format.

[0080] In step S305, the single-level directory information is queried based on the order identifier to obtain the target data node associated with the QR code.

[0081] In some embodiments, a target index range corresponding to the order identifier is obtained, and a target storage block corresponding to the target index range is determined. Based on the order identifier, index information corresponding to the order identifier is queried from the target storage block, and the target data node associated with the QR code is determined based on the index information.

[0082] For example, the index range includes "0-100000", "100001-200000", and "200001-300000", where the index range "0-100000" corresponds to storage block A, the index range "100001-200000" corresponds to storage block B, and the index range "200001-300000" corresponds to storage block C. If the order ID is 123456, the target index range corresponding to the order ID is "100001-200000", and the target storage block is storage block B. Based on the order ID, the index information corresponding to the order ID is queried from storage block B, and the target data node associated with the QR code is determined according to the index information.

[0083] In step S306, a data block is read from the target data node, the data block including payment information of the order information for subsequent payment operations.

[0084] For the introduction of step S306, please refer to the relevant content in the above embodiment, which will not be repeated here.

[0085] The present invention parses the QR code, obtains the order identifier carried by the QR code, queries the single-level directory information based on the order identifier, and obtains the target data node associated with the QR code. This can reduce the delay in data transmission and processing caused by network anomalies or data center anomalies, and supports parallel processing and data synchronization mechanisms through redundant data storage and single-level directory search, thereby improving the processing and access speed of payment requests and ensuring data integrity and consistency.

[0086] Figure 4 is a flowchart of a method for processing information according to a fourth embodiment of the present disclosure. Figure 4 As shown, the method comprises the following steps:

[0087] In step S401, order information sent by the first terminal device is received, a QR code is generated based on an order identifier carried in the order information, and the QR code is sent to the first terminal device for display.

[0088] In step S402, at least one data block is generated according to the order information.

[0089] For the introduction of step S401 to step S402, reference may be made to the relevant contents in the above embodiment, which will not be repeated here.

[0090] In step S403, the status information of the candidate data nodes of the distributed storage system is determined.

[0091] In some embodiments, the status information includes at least one or more of load information, online / offline status, storage capacity, and response time. The load information is used to determine the usage of resources such as memory of the candidate data node, the storage capacity is used to determine the available storage space of the candidate data node, the response time is used to determine the delay in the node processing the request, and the online / offline status is used to determine whether the candidate data node is working properly.

[0092] In step S404, load balancing is performed on the candidate data nodes according to the state information to obtain at least two target data nodes.

[0093] In some implementations, the candidate data nodes are load balanced according to the status information to obtain target candidate data nodes, and at least two data nodes belonging to different data centers are selected from the target candidate data nodes as target data nodes.

[0094] Load balancing is a key link to ensure system performance and availability. By monitoring and analyzing the status information of candidate data nodes, requests can be flexibly allocated to optimize resource utilization, reduce latency, and avoid single point failures. For example, if the status information includes load information, online / offline status, storage capacity, and response time, data nodes with online status, less data volume, large storage space, and short response time among the candidate data nodes are prioritized as target data nodes.

[0095] In step S405, the data blocks are redundantly stored in at least two target data nodes.

[0096] In some implementations, two target data nodes are determined from the candidate data nodes, and the data blocks are redundantly stored in the two target data nodes.

[0097] In some implementations, a plurality of target data nodes are determined from the candidate data nodes, and two or a preset number of target data nodes are randomly selected from the plurality of target data nodes to redundantly store data blocks.

[0098] In step S406, the single-level directory information of the distributed storage system is updated according to the target data node and the order identifier.

[0099] In step S407, the QR code sent by the second terminal device is received, and the single-level directory information is queried based on the QR code to obtain the target data node associated with the QR code.

[0100] In step S408, a data block is read from the target data node, the data block including payment information of the order information for subsequent payment operations.

[0101] For the introduction of steps S406 to S408, reference may be made to the relevant contents in the above embodiment, which will not be repeated here.

[0102] The present invention determines the status information of candidate data nodes of a distributed storage system, performs load balancing on the candidate data nodes based on the status information, obtains at least two target data nodes, and redundantly stores data blocks in the at least two target data nodes, which can reduce the delay of data transmission and processing caused by network anomalies or data center anomalies, realize the optimization and acceleration of the payment process, improve the flexibility of information processing, disperse the pressure of data processing, and improve the stability and availability of the system.

[0103] like Figure 5 As shown, in some embodiments, order information sent by the first terminal device is received, a QR code is generated based on the order identifier carried in the order information, and is sent to the first terminal device for display; at least one data block is generated according to the order information, the data block is stored in the target data node of the distributed storage system, and the single-level directory information of the distributed storage system is updated according to the target data node and the order identifier; a QR code sent by the second terminal device is received, the single-level directory information is queried based on the QR code, at least two target data nodes associated with the QR code are obtained, and the load information of each of the at least two target data nodes is obtained, the load information at least includes the current number of visits to the target data node, based on the load information, the first target data node is determined from the at least two target data nodes, and the data block is read from the first target data node, the data block includes payment information of the order information, which is used for subsequent payment operations. After the payment is successful, a response message can also be generated and sent to the first terminal device and the second terminal device.

[0104] The present disclosure combines order QR codes with single-level directory distributed redundant storage to speed up and optimize the payment process. The system not only improves payment speed and data reliability, but also optimizes user experience and system stability. The present disclosure can reduce data transmission and processing delays caused by network anomalies or data center anomalies, optimize and speed up the payment process, improve the flexibility of information processing, disperse data processing pressure, and improve system stability and availability.
