All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a service party periodically requests a two-dimensional code every day:
at the time of T00, the actual request quantity of the two-dimensional code application is small, the two-dimensional code application belongs to the service valley period, and the typical value is 100 requests per minute at 0 point in the morning;
at the time of T01, the actual request volume of the two-dimensional code application is large, and belongs to the peak period of the service, and typical values are as 4000 per minute at 9 am;
at time T10, a trough phase on the next day was entered, similar to time T00;
different transition change modes are provided between the valley period and the peak period along with different service scenes; the data trend reciprocates so periodically each day.
When the limited number of the two-dimensional code generation server generating the two-dimensional code, that is, the maximum generatable amount Max is 5000, the two-dimensional code generation server will generate a large amount of resource waste, and the resource will not be fully utilized. Therefore, the embodiment of the invention provides a two-dimensional code application method.
As shown in fig. 2, the two-dimensional code application method provided in the embodiment of the present invention includes:
s1, for a time period with preset duration, dividing the time period into a specified number of time segments; the preset time length is equal to a limit period of the two-dimensional code generation server for generating the two-dimensional code;
s2, obtaining a difference value between a theoretical request quantity and an actual request quantity of the real-time two-dimensional code application received in the time segment, and supplementing the two-dimensional code generation server with the application to generate the two-dimensional code if the difference value and the historical excess value are judged to be larger than 0;
and the number of the two-dimensional codes generated by the supplementary application is equal to the difference between the difference value and the historical excess value, and the historical excess value is used for representing the absolute deviation between the theoretical request quantity and the actual request quantity in all the time segments before the time segment in the preset time length.
Specifically, in the two-dimensional code application method provided in the embodiment of the present invention, the execution main body is a target server, the target server may be a local server or a cloud server, and the local server may be a computer, a tablet computer, a smart phone, and the like. The target server can serve a certain unit or company, the target server can be in communication connection with a client and a two-dimensional code generation server which are held by a user, the client is used for sending a two-dimensional code application request to the two-dimensional code generation server through the target server, and the two-dimensional code generation server is used for generating a two-dimensional code in real time through the two-dimensional code application request sent by the target server. It should be noted that the two-dimensional code in the embodiment of the present invention may be a generalized two-dimensional code, and may include an applet two-dimensional code, where the applet two-dimensional code may be a square two-dimensional code or a circular two-dimensional code, and this is not specifically limited in the embodiment of the present invention. In the embodiment of the invention, the small program two-dimensional code can be a WeChat small program two-dimensional code, correspondingly, the two-dimensional code generating server can be a WeChat server, and a certain number of two-dimensional codes are generated within a preset time length by recording time of the two-dimensional code generating server.
Step S1 is performed first. The preset time duration refers to a limit period for the two-dimensional code generation server to generate the two-dimensional codes, for example, if the wechat server generates 5000 two-dimensional codes at most every minute, the limit period is 1 minute, that is, 60 seconds. The limit number is 5000. For a time period with a duration of 1 minute, the time period may be first divided into a specified number of time segments, and the specified number may be set as required, specifically may be greater than or equal to 2, and is preferably 10. The dividing mode may be an average dividing mode, that is, 1 minute may be divided into 10 time segments on average.
Then, step S2 is executed. The time period is set to be M0-M1, x time segments are divided between M0-M1, and the value of x is greater than or equal to 2. For each time segment mi(i is more than or equal to 1 and less than or equal to x), and acquiring a time segment miThe theoretical request quantity D and the actual request quantity s of the received real-time two-dimension code applicationi. The theoretical request quantity D refers to the set time segment miThe maximum number of the generated two-dimensional codes can be applied to a two-dimensional code generation server in real time. The value of the theoretical request quantity D may correspond to the preset time length one to one, that is, different theoretical request quantities D are provided for different preset time lengths, and different time segments within the same preset time length correspond to the same theoretical request quantity D. Calculating theoretical request quantity D and actual request quantity siHas a difference of di＝D-si. On the basis, in order to consider the influence of the actual request quantity of the time segment which is earlier in time in each preset time length on the quantity (namely the supplement request quantity) of the supplement application generation two-dimensional codes of the time segment which is later in time, mutually independent historical excess quantity values S are respectively introduced into each preset time length. Historical excess value S at each time segment miThere is a corresponding value, and the corresponding values may be the same or different. The historical excess value refers to a time segment m in each preset time lengthiAnd the sum of the absolute values of the differences between the theoretical requested quantity and the actual requested quantity of each previous time segment is used for representing the absolute deviation of the theoretical requested quantity and the actual requested quantity in all the time segments which have passed in each preset time length. In each preset time length, the initial value of the historical excess value S is 0, and the history can be carried out according to the absolute value of the difference between the theoretical request quantity and the actual request quantity of different time segmentsAnd adjusting the value of the history excess value S.
Judging the difference diThe difference Diff between the historical excess value S and the positive or negative value of Diff, if Diff is greater than 0, the time segment m is describediThe total amount of the two-dimension codes applied in the internal application is insufficient, and m can be segmented in time at the momentiAnd when the two-dimensional code generation is finished, continuing to supplement the two-dimensional code generation server for generating the two-dimensional code, wherein the supplement application amount is equal to Diff. That is, if Diff is greater than 0, time segment m is now presentiThe surplus of the requested amount of the inner two-dimensional code is Diff, and a supplement application can be carried out. The resource of the two-dimensional code generation server can be fully utilized, and the utilization rate of the resource is greatly improved. It should be noted that the time segment miThe total amount of the two-dimension code of the internal application is time segmentation miActual request quantity s of inner two-dimension codeiAnd time segment miThe sum of the historical excess values S.
The two-dimension code application method provided by the embodiment of the invention comprises the steps of firstly dividing a time period with preset duration into a specified number of time segments; the preset time length is equal to a limit period of the two-dimensional code generation server for generating the two-dimensional code; then obtaining a difference value between a theoretical request quantity and an actual request quantity of a real-time two-dimensional code application received in each time segment, and supplementing the two-dimensional code generation server with the application to generate the two-dimensional code in the time segment if the difference value is judged to be larger than 0 with the historical excess value; and the number of the two-dimensional codes generated by the supplementary application is equal to the difference between the difference value and the historical excess value. The supplementary application and the real-time application are combined, so that the resources of the two-dimensional code generation server can be fully utilized, and the utilization rate of the resources is greatly improved.
On the basis of the above embodiment, after the supplementary application, the historical excess value S needs to be set to 0, so as to illustrate that the time slice m is divided into time slicesiThe resource of the two-dimensional code generation server is fully utilized, and the resource waste is avoided.
On the basis of the above embodiment, the two-dimensional code application method provided in the embodiment of the present invention further includes:
if the difference between the difference value and the historical excess value is smaller than 0, keeping the absolute value two-dimensional codes of the difference value and the historical excess value until the next time segment of the time segment is applied after the theoretical request quantity two-dimensional codes are applied in the time segment in real time.
Specifically, in the embodiment of the present invention, since a maximum number of two-dimensional codes of theoretical request amount can be applied in real time in each time segment, when Diff is smaller than 0, it is described that the time segment m isiThe total amount of the two-dimension codes applied in the internal application is too much, and the time segment m is divided intoiThere is no surplus limit for supplement application, not only, time segment miThe theoretical amount of requests in is not sufficient to satisfy the time segment miThe actual request amount and the history excess amount in the time slice miNext time segment m ofi+1In time division miThe request quantity which is not applied in the middle is continuously applied, and the time is segmented miThe requested quantity is the difference diThe absolute value of the difference from the historical excess value S. Therefore, in the embodiment of the present invention, m is time-segmentediAfter internal real-time application of theoretical request quantity of two-dimensional codes, difference value d is obtainediThe absolute value of the difference from the historical excess value S is retained until the time segment miNext time segment m ofi+1And (6) applying.
In the embodiment of the invention, after the two-dimension codes with the theoretical request quantity applied in each time segment in real time are limited, the rest two-dimension codes are reserved to the next time segment for application, so that the two-dimension code request quantity in the time segment with the preset time length can be more average in each time segment.
On the basis of the above embodiment, the two-dimensional code application method provided in the embodiment of the present invention further includes: and if the difference between the difference value and the historical excess value is judged and obtained to be smaller than 0, updating the historical excess value to be the absolute value of the difference between the difference value and the historical excess value.
Specifically, in the embodiment of the present invention, when Diff is smaller than 0, m needs to be segmented in timeiNext time segment m ofi+1In time division miThe requested amount that has not been applied for is applied for further, specifically, the following steps are followedA time segment mi+1Is updated to diThe absolute value of the difference from the historical excess value S, in time segments miNext time segment m ofi+1Continuously judging the actual request quantity di+1Plus or minus the difference with the updated historical excess value S.
On the basis of the above embodiment, the two-dimensional code application method provided in the embodiment of the present invention further includes: and if the difference between the difference value and the historical excess value is judged and obtained to be equal to 0, continuously obtaining the difference value between the theoretical request quantity and the actual request quantity of the real-time two-dimensional code application received in the next time segment of the time segments.
Specifically, in the embodiment of the present invention, when the difference d is smaller than the predetermined valueiThe difference between the historical excess value S and the historical excess value S is equal to 0, which indicates the actual request quantity S of the two-dimensional code applied in real timeiThe two-dimensional code generating server can just meet the requirement, and no residual resource is left for performing supplementary application to generate the two-dimensional code.
On the basis of the above embodiment, the two-dimensional code application method provided in the embodiment of the present invention further includes: storing the two-dimensional code generated by the supplementary application;
and when a result corresponding to the real-time two-dimensional code application request returned by the two-dimensional code generation server is empty, returning the stored two-dimensional code to the client.
Specifically, in the embodiment of the present invention, the two-dimensional code generated by the supplement application is stored. When the actual request quantity of the real-time application of the two-dimensional code is larger than the limited quantity of the two-dimensional code generation server, namely, a result corresponding to the real-time two-dimensional code application request returned by the two-dimensional code generation server is empty, namely, the two-dimensional code generation server fails to generate the two-dimensional code, the stored two-dimensional code can be directly returned to the client.
In the embodiment of the invention, the two-dimensional code obtained by the supplement application can be fully utilized on the basis of fully utilizing the resources of the two-dimensional code generation server.
On the basis of the foregoing embodiment, in the two-dimensional code application method provided in the embodiment of the present invention, the theoretical requested quantity is specifically a ratio of the limited quantity of the two-dimensional codes generated in the limited period to the specified quantity.
Specifically, in the embodiment of the present invention, the theoretical requested quantity is specifically a ratio of a limited quantity of the two-dimensional codes generated in the limited period to the specified quantity. For example, if the limited number is 5000 and the specified number is x, the theoretical request amount is 5000/x, which is an average value of two-dimensional code application amounts in a time period, and it is ensured that resources of the two-dimensional code generation server are fully utilized. At most 5000/x two-dimensional code missing applications exist per minute. If x is divided into a plurality of sections, the missing two-dimensional codes are fewer, the overall application rate is closer to 100%, and finally the sum of magnitude of real-time application and supplementary application per minute can be close to or equal to 5000.
