For the purpose of facilitating an understanding of the embodiments of the present application, a brief introduction will be made below to some concepts proposed in the embodiments of the present application:
frequency control: the short term frequency control refers to a policy for controlling the number of calls of one or more interfaces in a unit time, so as to ensure that Interface services of an Application Program Interface (API) are not impacted by a large number of requests, and ensure the overall stability of a platform.
Frequency quota: the frequency quota is referred to as a frequency threshold in the embodiment of the application.
System capacity: the total number of requests that the current platform system can support will decrease the value of the system capacity each time a caller requests.
The calling party: which means any user that uses the API to perform the service feature, for example, a terminal or a server.
History call log: the service of each caller calls a record of request information, such as the time point of the request, the requester, Uniform Resource Locator (URL), header, and responder.
Query Per Second rate (Query Per Second, QPS): the number of requests that can be processed by the server in one second is shown, for example, in the embodiment of the present application, QPS is used as a unit to measure the interface call frequency.
In the related art, a fixed value is usually statically allocated to a calling frequency control manner, including a frequency quota for a single caller and a frequency quota of an entire system platform, for example, a fixed frequency quota Q is allocated when a caller calls an interface for the first time, in a following P period, if the number of times that the caller accesses an API is greater than Q, a service call request of the caller is rejected, and after the P period, the frequency quota is reset to Q.

Fig. 1 is a schematic diagram of an application architecture of a call frequency control method according to an embodiment of the present application, including a caller 100, a verification server 200, and a service server 300.
The caller 100 is a user who calls an interface of the platform system to complete a corresponding service, and may be a third party server, and may also be a terminal device, and this embodiment is not limited in this application, and the caller 100 may communicate with the service server 300 and the verification server 200 through external interfaces, for example, the caller 100 may access the platform through an interface provided by the platform system, and then the caller 100 sends a service call request to the verification server 200 through the accessed interface, and when the verification server 200 performs verification to allow the service call request, the service call request is forwarded to the service server 300, so that the service server 300 may perform service processing on the service call request, and the service server 300 may also send a service processing result of the service call request to the caller 100.
The verification server 200 and the service server 300 are both background servers providing services, the service server 300 is mainly used for performing service processing on the service call request, the verification server 200 is mainly used for verifying the service call request of the caller 100, judging whether the call frequency of the caller 100 sending the service call request through the target interface exceeds the current frequency threshold value, and the frequency threshold of the caller 100 may be dynamically calculated and assigned in the embodiment of the present application, the dynamic computation function for the frequency threshold may be implemented by being integrated into the verification server 200, or may be implemented as a separate quota computation server, in contrast, in the embodiment of the present application, there is no limitation, and of course, the verification server 200 and the service server 300 are also divided according to functions, and may also be implemented by being integrated on one server, and the embodiment of the present application is not limited.

Based on the foregoing embodiment, referring to fig. 2, a flowchart of a method for controlling call frequency in the embodiment of the present application is shown, where the method includes:
step 200: and determining the current frequency threshold of the calling party for the accessed target interface in the target time period.
In the embodiment of the present application, each caller may allocate a fixed frequency threshold when accessing the API, for example, the system capacity is 1000qps, where an initial value of the system capacity is usually an empirical value, the system capacity may also be modified when the system capacity is increased and becomes effective, and a caller may allocate 10qps for the caller to use when accessing, that is, the initial frequency threshold of the caller.
It should be noted that, when different callers access the same interface, the frequency threshold assigned by each caller may not be the same, and when the same caller accesses different interfaces, the frequency thresholds assigned by each interface may also be different, that is, the assignment of the frequency thresholds is for one caller and one interface.
In order to improve accuracy and effectiveness of the calling frequency control in the embodiment of the present application, based on the initial frequency threshold, the current frequency threshold of each time period is dynamically allocated, and the specific execution of step 200 includes:
and S1, acquiring historical calling information of the calling party in a preset historical time.
The preset historical duration may be a period of time before the current computing time, for example, a historical call log of the past 7 days.
Moreover, the preset historical duration is greater than the duration of the divided time periods, and the preset historical duration may include a plurality of time periods, for example, the preset historical duration is in days, and the time period is in minutes, which is not limited in the embodiment of the present application.
And S2, respectively counting the times of sending the service calling requests in each time period with preset historical duration according to the historical calling information.
For example, historical call information of the last 7 days is obtained, the unit of each time period is minute, statistics is performed in a manner of 1 point per minute, and total 7 × 24 × 60 points of service call request data of each caller can be recorded, where the service call request data of each point at least includes the number of times of sending the service call request, that is, the number of times of sending the service call request corresponding to each minute of each day in the last 7 days is obtained.
And S3, respectively determining the weighted average of the counted times of each corresponding same time period in the preset historical time length.
For example, taking a calling party as an example, if historical call information of the past 7 days is obtained, there should be 7 statistical times for sending the service call request in the daily 00:01 time period, and the 7 times may be added and averaged, and then multiplied by 120%, so as to obtain a weighted average value of the time period.
And S4, taking the maximum value of the initial frequency threshold of the target time period and the weighted average value of the same time period in the corresponding preset historical duration as the current frequency threshold of the target time period.
The target time period is one of the time periods, for example, the weighted average of the times corresponding to the target time period is 50qps, the initial frequency threshold is 10qps, the maximum value of the two, that is, 50qps is taken as the current frequency threshold of the target time period, so that the current frequency threshold of the single interface per minute on the single day of the calling party can be calculated and obtained.
In this way, in the embodiment of the present application, for each caller, by analyzing historical call information such as historical call trends and peaks, the current frequency threshold corresponding to each current time period can be predicted.
Further, dynamic modification may be performed according to the predicted current frequency threshold of each time period, for example, a time point at which the frequency threshold may be insufficient may be predicted, and the allocated frequency threshold may be modified before the arrival.
For example, by analyzing and predicting that a caller 9 am may have a call requirement of 50qps, then the call may be made at 8: 55, the caller's frequency threshold is modified from 10qps to 50 qps.
Therefore, when the modification is carried out at a certain moment before the target time period comes, a certain error can be allowed, the accuracy of frequency threshold value distribution is improved, and the normal calling of a calling party is ensured as much as possible.
Step 210: and in the target time period, when a service calling request sent by a calling party through a target interface is received, obtaining the current frequency balance in the target time period according to the current frequency threshold and the called times of the calling party through the target interface in the target time period.
For example, if the current frequency threshold is 10qps, the number of times that the target interface has been invoked in the target time period is 3, and the current frequency balance is (10-3) qps.
Step 220: and if the current frequency balance is determined to be exhausted, acquiring the current resource use information.
The current resource usage information at least includes usage ratio values of each index representing the current resource, such as usage ratio values of a CPU, a memory, a network card, and the like, and of course, other indexes representing the current resource may also be used, which is not limited in the embodiment of the present application.
Further, if it is determined that the current frequency balance is not exhausted, that is, there is a margin, the service call request is allowed, the service logic is normally executed, and the frequency deduction may be performed after the service call request is completed. Therefore, the current frequency balance is calculated in real time according to each service calling request, and the efficiency can be improved.
Step 230: and adjusting the current frequency threshold according to the current resource use information.
When step 230 is executed, the method specifically includes:
1) and determining the remaining capacity of the system according to the current resource use information.
Specifically, the method comprises the following steps: carrying out weighted average on the use proportion value of each index according to the corresponding weight of each index, and taking the weighted average value of each index as the used capacity of the system; and determining the remaining capacity of the system according to the used capacity of the system.
For example, if the CPU usage ratio is 40%, the corresponding weight is 0.6, the memory usage ratio is 30%, the corresponding weight is 0.3, the network card usage ratio is 10%, and the corresponding weight is 0.1, the used capacity of the system may be represented as: 0.4 × 0.6+0.3 × 0.3+0.1 × 0.1 ═ 0.34 (34%), and the remaining system capacity was determined to be 66%.
The used capacity of the system is positively correlated with the current resource use information, and the used capacity of the system is reduced along with the reduction of the use proportion value of the CPU, the memory and the network card, so that the purpose of automatically adjusting the capacity of the platform system can be realized.
In addition, the used capacity or the remaining capacity of the system may be manually reported by a relevant person in real time, or an interface may be provided by the service server for the verification server to directly read, which is not limited in the embodiment of the present application.
2) And if the residual capacity of the system is determined to exceed the preset threshold, increasing the current frequency threshold by a preset proportion.
The preset threshold may be set according to actual conditions and requirements, for example, set to 20%, and this embodiment of the present application is not limited.
For example, if the remaining system capacity is 66% > 20%, the current frequency threshold of the calling party for the target interface may be adjusted up by 20%, at this time, since the current frequency threshold is increased, the current frequency balance is correspondingly increased, and the current frequency balance is not 0, the service of the calling party may be continuously supported.
Further, when a service invocation request is sent in the target time period in the following, if it is determined that the current frequency threshold is exhausted again, the above steps 220 to 230 may be repeatedly executed until the remaining capacity of the system does not exceed the preset threshold.
Further, if the remaining system capacity does not exceed the preset threshold, the service invocation request is rejected, and at this time, the service invocation request of the caller fails, which indicates that the system capacity is not enough and corresponding service logic cannot be executed.
In the embodiment of the application, a current frequency threshold value of an access target interface of a calling party in a target time period is determined, and then when a service calling request sent by the calling party through the target interface is received in the target time period, a current frequency balance in the target time period is obtained according to the current frequency threshold value and the called times of the calling party through the target interface in the target time period; if the balance of the current frequency is determined to be exhausted, the current resource use information is obtained, and the current frequency threshold value is adjusted according to the current resource use information, so that the current required frequency threshold value can be predicted by analyzing the historical calling information such as the calling rule, the trend and the like of the calling party, and the current resource use information of the system can be combined, so that the frequency threshold value of the target interface is dynamically allocated by the calling party, the system resources can be fully utilized, the effectiveness and the accuracy of frequency threshold value allocation are improved, the normal calling of the calling party can be guaranteed as far as possible on the premise of ensuring the permission of a platform, and the influence on the online production of the calling party is reduced.
Based on the foregoing embodiment, a specific application scenario is described below, taking the example that three callers access through the same target interface a respectively, and for better clarity, a dynamic computation function for a frequency threshold is integrated in an independent quota computation server to be implemented, so that the entire system architecture may include a service server, a frequency check server, and a quota computation server, where the service server is represented in a cluster form, and specifically refer to fig. 3, which is an overall schematic structural diagram of a call frequency control method in the embodiment of the present application.
Based on the foregoing embodiment, it can be seen that two aspects are mainly implemented in the embodiment of the present application, on one hand, performing frequency verification when receiving a service invocation request, and adjusting a current frequency threshold according to a system residual capacity, where the adjustment when receiving the service invocation request is mainly a real-time adjustment stage, and on the other hand, predetermining a current frequency threshold in a target time period, where analysis and prediction need to be performed in advance, and the adjustment stage is mainly an asynchronous adjustment stage, specifically:
in a first aspect: and (5) adjusting in real time.
1) As shown in fig. 3, for example, caller a, caller B, and caller C are all accessed through target interface a, and a fixed frequency threshold is assigned when accessing target interface a, caller a is 10qps, caller B is 50qps, and caller C is 100 qps.
2) Taking the caller a as an example, if the caller a sends a service invocation request, the verification server performs frequency verification when receiving the service invocation request.
If the current frequency balance is determined not to be exhausted, the service calling request is forwarded to the service server to normally execute the service logic, frequency deduction is performed after completion, namely deduction is continuously performed by taking the current frequency threshold as an initial value, one service calling request is subtracted by 1, for example, the current frequency threshold is 10 times per second, namely maximum 10 calling times are allowed in one second, and deduction is performed by taking 10 as the initial value every second.
If the current frequency balance is determined to be exhausted, dynamic allocation is performed again in combination with the system capacity, for example, the number of times of service call requests within a certain second exceeds 10, that is, the current frequency balance is 0, the system residual capacity is determined, for example, as shown in fig. 3, the service server may report current resource usage such as load, hardware usage and the like to the quota calculation server, and the verification server may also report information such as a verification result and processing delay of the service call requests to the quota calculation server, so that the quota calculation server may determine the system residual capacity in combination with the information, and then the quota calculation server sends the system residual capacity to the verification server, the verification server may further determine according to the system residual capacity, and if it is determined that the system residual capacity exceeds a preset threshold, a preset proportion is increased to the current frequency threshold, and if the residual capacity of the system is determined not to exceed the preset threshold value, rejecting the service call request.
In a second aspect: and (4) asynchronous adjusting phase.
As shown in fig. 3, the quota calculation server may obtain a history call log, that is, history call information, according to the history call information, analyze and count the calls for each caller, and predict a frequency threshold of a target time period of the current day, for example, a frequency threshold allocated when the caller a initially accesses is 10qps, and predict a call frequency required in a certain target time period to be 50qps through the history call information, the frequency threshold of the caller a may be modified from 10qps to 50qps before the target time period arrives, and the quota calculation server sends a current frequency threshold 50qps determined for the target time period to the verification server, so that the verification server performs frequency verification based on the current frequency threshold 50 qps.
Therefore, in the embodiment of the application, the dynamic frequency threshold value is distributed through the historical calling information and the current system residual capacity, the whole safety and stability of the platform can be ensured, the online production interruption caused by the fact that the calling party touches the interface frequency threshold value is effectively avoided, and the normal service calling of the calling party is ensured as much as possible.
In addition, it should be noted that the call frequency control method in the embodiment of the present application may be applied to various scenarios that need frequency control protection, including scenarios that need different frequency control policies for multiple callers, and scenarios that may exist under the scenarios and involve some dynamic quota allocation requirements, thereby achieving dynamic frequency quota allocation.
