Cloud Computing (Cloud Computing) refers to obtaining required resources in an on-demand, easily-extensible manner over a network; the generalized cloud computing refers to a delivery and use mode of a service, and refers to obtaining a required service in an on-demand and easily-extensible manner through a network. Such services may be IT and software, internet related, or other services. Cloud Computing is a product of development and fusion of traditional computers and Network Technologies, such as Grid Computing (Grid Computing), distributed Computing (distributed Computing), Parallel Computing (Parallel Computing), Utility Computing (Utility Computing), Network Storage (Network Storage Technologies), Virtualization (Virtualization), Load balancing (Load Balance), and the like.

With the development of diversification of internet, real-time data stream and connecting equipment and the promotion of demands of search service, social network, mobile commerce, open collaboration and the like, cloud computing is rapidly developed. Different from the prior parallel distributed computing, the generation of cloud computing can promote the revolutionary change of the whole internet mode and the enterprise management mode in concept.

In order to generate a unique resource identifier in a distributed system supporting cloud computing, the prior art provides several feasible solutions:

(1) self-increment identification by using database

The auto _ increment field of MySQL is used for realizing the self-increment identification, or the Redis is used for realizing the self-increment identification, and different step lengths can be set for different application scenes to generate the unique identification. The unique and ordered generated identification can be ensured by utilizing the self-increment identification of the database, and the use method is simple; but it requires independent deployment of databases or Redis instances, is costly to use, and has performance bottlenecks.

(2) Generating, by a server, an identity in combination with related parameters local to the server

The unique identifier can be obtained by the server through calculation by combining the local network card address, the local time and the random number. The server can generate the identifier locally in the server by combining the local related parameters of the server, the use method is simple, the performance is good, and the distributed application scene is met; however, the identifier generated by the scheme has a fixed format and a long length, occupies a large storage space, and is disordered and unreadable.

(3) Twitter snowfly algorithm

The identifier generated by the Twitter snowfall algorithm is fixed to 64 bits and comprises four fields: 1-bit sign bit, 41-bit timestamp difference, 10-bit machine number and self-increment identification within 12-bit millisecond. The uniqueness of the identification in a distributed scene can be ensured, the generation performance is high, and the identification is ordered according to time; however, this solution requires independent development and deployment, depends on the server local time, and has an upper limit on the size of unique identifiers that can be supported because of the length constraints of the timestamp difference and the machine number field.

(4) Generating an identity based on existing open source components supporting distributed systems

The identification is generated by relying on the components such as the database, the Zookeeper and the like, so that the resource identification obtained in a distributed scene is ensured to be globally unique and monotonically increased, and the safety is high.

The solutions capable of ensuring the uniqueness of the resource identifier in the prior art are both advantages and disadvantages, have their own application scenarios and limitations, and none of the solutions can generate the resource identifier capable of being expanded at will with high flexibility without depending on the existing switch components. To this end, an embodiment of the present invention provides a resource identifier generating method, which aims to provide a solution for generating a resource identifier:

(1) the method has good expansibility, can be applied to different application scenes, can ensure the overall increasing trend of the distributed generation of the resource identifiers, is globally unique, and can index the resource identifiers generated in different applications to corresponding services;

(2) the information security of the unique resource identifier can be guaranteed, a user cannot acquire any connotation information from the resource identifier, so that the resource identifier cannot be forged, even if an algorithm for generating the resource identifier is leaked, the generated resource identifier cannot be directly reproduced through the algorithm, and violent polling is still required, so that the cracking difficulty is improved.

(3) And each resource identifier can be subjected to validity check, and the execution efficiency is better.

First, the embodiment of the present invention discloses an implementation environment of the resource identifier generation method in a possible embodiment.

Referring to fig. 1, the implementation environment includes: at least one client 01 and a server 03.

The client 01 may be an entity device for interacting with the server 03, and the client 01 may further include software running in the entity device, for example, a related program that runs to obtain a service provided by the server 03 and interacts with the server 03. The Client 01 may be communicatively connected to the Server 03 based on a Browser/Server mode (Browser/Server, B/S) or a Client/Server mode C/S (Client/Server, C/S).

The server 03 may be a distributed server or any one server in a server cluster composed of a plurality of servers. The server 03 supports cloud computing in a distributed architecture and provides cloud services. Any one of the servers 03 may independently run the resource identifier generation method to obtain a resource identifier that has uniqueness and can index to a service provided by the server.

An embodiment of the present invention provides a resource identifier generating method, as shown in fig. 2, where the method may be run in a server in a distributed system, and the method includes:

s101, a resource identification generation strategy is obtained, wherein the resource identification generation strategy comprises identification structure information and splitter information, the identification structure information is used for representing the adjacency relation between the information of a part structure and the part structure, the part structure at least comprises a service part and a change part, the service part points to the service used for representing the relation between the service and the resource identification, and the change part points to a field used for representing and ensuring the uniqueness of the resource identification.

The resource identifier generated in the embodiment of the present invention may be configured by a plurality of part structures, and the content and the proximity relation of each part structure are recorded in the identifier structure information, and the resource identifier at least includes a service part and a change part. The service part points to a service associated with a resource identifier, the resource identifier is required to be used in the service or the service is used for generating the resource identifier, so that the service can be indexed to according to the resource identifier, and the resource identifiers corresponding to different services in a distributed system can be ensured to be different, which is a necessary condition for ensuring the uniqueness of the resource identifier. The change part points to the changed field in the resource identification, and even if the resource identification is generated by the same server based on the same service, the content of the field pointed by the change part is necessarily different, so that the uniqueness of the resource identification is ensured.

As shown in fig. 3, it shows a resource identifier in a possible embodiment, the resource identifier is composed of a service part, an encryption part, an activity part and a change part, and the contents of the service part, the encryption part, the activity part and the change part are sequentially spliced by separators to obtain the resource identifier. Specifically, the contents of the respective sections are as follows:

a service part: the resource identifier is generated for the service corresponding to the service field by the machine corresponding to the machine number. The service part is arranged so that the resource identifier generation method provided by the embodiment can support the expansion of each service and each machine, and after different numbers are allocated to different services and machines, the resource identifier generation method can be independently implemented.

An encryption unit: when the length of the resource identifier is required, the length can be supplemented by arranging an encryption part, and the encryption part can be generated by using an encryption algorithm to enhance the safety of the resource identifier, and even if the resource identifier generation algorithm is leaked, the resource identifier cannot be directly reproduced. The encryption unit may be configured by a random string. The encryption unit itself may be a ciphertext or a plaintext. The encryption part is arranged to supplement the length of the resource identifier and improve the cracking difficulty of the resource identifier.

A movable part: the setting of the activity part is extensible, which can make the generation of the resource identifier meet any granularity requirement, the activity part may include at least one level of activity identifier, the activity identifier may also be a multi-level identifier, and the more the number of levels of the activity identifier, the smaller the granularity. The resource identifier generation method in the embodiment of the invention can support the resource identifier generation of single-service single-machine single-activity granularity and the resource identifier generation of activities of any granularity, so that the resource identifiers can be generated according to batches.

A changing part: the change part is related to the activity part and is used for distinguishing the resource identifiers generated aiming at the same activity, and the change part can be generated by setting a step length and carrying out a self-increment rule.

In a preferred embodiment, in order to facilitate checking the resource identifier, the resource identifier may further include a checking portion, and the checking portion may be attached to a tail portion or other designated position of the resource identifier.

The purpose of dividing each part structure by a separator in the resource identifier is to make the length of the content corresponding to each part structure free and not fixed, and to make the resource identifier expandable, and the length of each part structure and the overall length of the resource identifier can be changed as needed. In a preferred embodiment, the identifier corresponding to the separator is an identifier not included in the content corresponding to each part structure, so that the separation function can be achieved.

In fig. 3, "EB" is a service section, "HB" is an encryption section, "4U" is an active section, "HBT" is a change section, "8" is a verification section, and "Z" is a delimiter.

And S103, extracting the part structures in the identification structure information, and acquiring the information to be spliced corresponding to each part structure.

Specifically, the extracting a partial structure in the identification structure information and obtaining information to be spliced corresponding to each partial structure, as shown in fig. 4, includes:

and S1031, acquiring a service identifier pointed by the resource identifier and a server identifier of the server, and acquiring first information corresponding to the service part according to the service identifier and the server identifier.

S1033, obtaining second information corresponding to the change part based on a local self-increment algorithm.

Different from a self-increment algorithm for generating the identifier in the distributed system in the prior art, the self-increment algorithm in the prior art must ensure that the identifier is self-incremented in the global state of the distributed system, and the generated identifier can be ensured to have uniqueness in the distributed system. In the embodiment of the invention, the change part is generated only by the local self-increment of the server without considering other servers or other components in the distributed system, and because the service parts of the resource identifiers generated by different servers are different, the whole pressure for distinguishing the resource identifiers is not required to be concentrated in the change part, so the change part is obtained only based on the local self-increment algorithm of the server, and the difficulty of the self-increment algorithm is obviously greatly reduced compared with the prior art. The server local autonomic algorithm can be implemented based on the prior art, and the embodiment of the invention does not limit the specific implementation means.

In particular, the server local auto-increment algorithm can be implemented using existing database auto-increment algorithms, such as auto _ increment field of MySQL or Redis. Because the self-increment in the embodiment of the invention does not need to consider the whole situation, and only needs to ensure the self-increment of the change part of the resource identifier in a single server, the parallel capacity expansion can be supported, and the single-point performance bottleneck can not occur.

In a preferred embodiment, the identification structure information further includes an encryption portion, a movable portion, and a verification portion, the extracting a partial structure in the identification structure information to obtain information to be spliced corresponding to each partial structure further includes:

and S1035, obtaining an encryption character string according to a preset encryption algorithm, and taking the encryption character string as third information corresponding to the encryption part.

In a possible embodiment, the obtaining of the encrypted string according to the preset encryption algorithm, as shown in fig. 5, includes:

s10351, a target length of the encryption unit is acquired.

Specifically, the target length can be determined according to actual requirements, and can be flexibly increased and decreased.

And S10353, randomly selecting characters with target length quantity in an encryption character mapping table to form an encryption character string, wherein the characters in the encryption character mapping table are all used for generating an encryption part.

S1037, activity information is obtained, and fourth information corresponding to the activity portion is obtained according to the activity information.

S1039, obtaining fifth information corresponding to the verification part according to the first information, the second information, the third information and the fourth information.

If the subsequent processing is not performed, the first information, the second information, the third information, the fourth information and the fifth information can be directly used as the information to be spliced.

In a preferred embodiment, to further increase the security of the resource identifier, the information corresponding to each partial structure may be optionally transcoded. Specifically, the identification structure further includes transcoding information, where the transcoding information includes at least one transcoding item, where the transcoding item is used to represent a transcoding requirement of a partial structure corresponding to the transcoding item, the partial structure in the identification structure information is extracted, and information to be spliced corresponding to each partial structure is obtained, as shown in fig. 6, the method further includes:

and S10311, obtaining all transcoding items in the transcoding information.

And S10313, transcoding the information of the partial structure corresponding to the transcoding item according to each transcoding item to obtain the information to be spliced corresponding to the partial structure.

In particular, the transcoding may be implemented based on a binary conversion.

Specifically, the transcoding requirement in the transcoding item may include a mapping method and a mapping table, where the mapping method is used to describe a relationship between the information of the partial structure and the mapping table, and a result obtained by mapping the information of the partial structure to the mapping table is used as the information to be spliced corresponding to the information of the partial structure.

In another preferred embodiment, the information of the verification portion may be generated based on information of each partial structure before transcoding, or may be generated based on information to be spliced corresponding to each partial structure after transcoding. For convenience of description, in the embodiment of the present invention, each piece of information used for generating the information of the verification portion is referred to as input information, and the input information may be information of a partial structure or information to be spliced corresponding to the partial structure. An embodiment of the present invention provides an information generating method of a verification portion, as shown in fig. 7, including:

s1, acquiring each input information;

and S3, sequentially obtaining the ASCII code values of the characters of the input information according to the adjacency relation of the input information.

And S5, accumulating and summing the obtained ASCII code values of the characters of each input message to obtain a sum value.

And S7, taking a module of the total sum value relative to the total number of elements in the encrypted character mapping table to obtain a check number.

And S9, taking the content corresponding to the check number in the encrypted character mapping table as the information of the check part.

And S105, acquiring the separator according to the separator information.

Specifically, a separator mapping table may be maintained, and separators may be extracted from the separator mapping table according to the separator information.

And S107, obtaining resource identification according to the adjacent relation of the part structures in the identification structure information and the information to be spliced adjacent to the separator connecting part structure.

The resource identifier generated by the embodiment of the invention comprises various information, such as information of the service part and information of the activity part, the resource identifier can be managed based on the information, and the resource identifier can be indexed through the information of the service part and/or the information of the activity part. In practical application, different machines can generate and store the resource identifier independently, and for application with higher performance requirements, the resource identifier can be generated in advance in large batch, because the resource identifier in the embodiment of the invention is generated without depending on real-time information such as a time stamp and the like, the resource identifier can be stored in a fragmentation mode based on business, machines and single-activity identifiers, and the change part in the resource identifier is used for indexing, so that better writing and query performance can be achieved compared with the prior art which simply uses a character string index or a numerical index without actual business meaning.

The embodiment of the invention discloses a resource identifier generation method, which obtains information of a plurality of partial structures according to a resource identifier generation strategy and generates a resource identifier based on a step of splicing the information by separators, so that the resource identifier generation method at least has the following advantages:

(1) in a distributed scene, each server only needs to independently generate a resource identifier, so that the generated resource identifier can be ensured to be globally unique in a distributed system, the global management cost is saved, and the generation difficulty of the resource identifier is reduced.

(2) The structure of each part of the resource identifier can be expanded at will, and the length of the resource identifier is not fixedly limited, so that the generation of the resource identifier with any granularity and any length is supported theoretically.

(3) The resource identifier is provided with the encryption part, so that the security of the resource identifier can be improved, and even if the resource identifier generation algorithm is leaked, the resource identifier cannot be directly reproduced, so that the resource identifier is also safe to a certain extent, and therefore, the resource identifier can be applied to scenes with higher requirements on the resource identifier.

(4) The resource identifier can be transcoded or encrypted at the granularity of the partial structure, so that the safety of the resource identifier is further improved, and the plaintext information of the partial structure can be hidden through transcoding, thereby being beneficial to ensuring the information safety of the resource identifier.

Corresponding to the resource identifier generation method, the embodiment of the present invention further discloses a verification method for the resource identifier, as shown in fig. 8, where the verification method includes:

And S205, calculating target verification information according to the analysis result corresponding to each information part.

The calculation method of the target check information is consistent with the generation method of the information of the check part in the generation method of the resource identifier, and is not described herein again.

And S207, if the target verification information is consistent with the analysis result of the verification part, the verification is passed.

The method for verifying the resource identifier according to the embodiment of the present invention and the method for generating the resource identifier are inverse processes, and details are not repeated here.

In a preferred embodiment, in order to avoid a hacker from cracking the resource identifier by means of brute force polling, the resource check request submission rate of the user may be limited, or an upper limit on the number of requests per day of the user may be set.
