Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, terms such as "first," "second," "third," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance or order.
As mentioned above, the current throttling mode generally sets a fixed limiting limit, so as to limit the access requests of each client, and limits the frequency of the access requests to the clients exceeding the limiting limit. However, this current limiting method of setting the fixed current limit is to use the fixed current limit to target each client without distinction, so the current limiting effect is generally poor.
In view of this, embodiments of the present application provide a method, apparatus, electronic device, and storage medium for limiting access to a server, which can be used to solve the technical problem. The method can be applied to gateway equipment in a server, and further the gateway equipment is used for executing the method provided by the embodiment of the application to limit the access request of the client. Fig. 1 is a schematic flow chart of a method for limiting access to a server according to an embodiment of the present application, where the method includes the following steps:
step S11: the access frequency of the client is determined.
In practical applications, a server is typically connected with a plurality of clients, and each of these clients may send an access request to the server, so the server may typically perform a current limit for any one or several of these clients. Therefore, the client in step S11 may be any client connected to the server, or may be a selected client, for example, each client that sends an access request to the server may be used as a selected client, and further, the client is limited by the method provided in the embodiments of the present application.
For example, after the client transmits an access request to the server, the gateway device in the server receives the access request, and in this case, when the access request of the client is received, the gateway device can determine the access frequency of the client by using the gateway device as the selected client for the client that transmitted the access request, in step S11.
The access frequency of the client may be the number of times that the client sends an access request to the server in a preset time period, where the preset time period may be 1 minute, 30 minutes, 1 hour, 1 day, 3 days, or other time period. Generally, the number of times that the client sends an access request to the server in a preset period of time can be determined by querying an access record of the client, so as to obtain the access frequency of the client. For example, the preset period of time is 1 hour, and in the preset period of time, the number of times that a certain client sends an access request to a server is 30, and at this time, the access frequency of the client is 30.
In addition, the server is usually connected to a plurality of clients, each client may send an access request to the server, where the gateway device of the server may obtain the access request of the client for the access request sent by each client, and in order to improve security, the access request may also carry authorization information, so that the gateway device may determine whether the client has access rights according to the authorization information, and if the client has access rights, perform the above step S11 to determine the access frequency of the client.
Step S12: and judging whether the access frequency of the client is greater than the dynamic current limit.
The dynamic limit is obtained by dynamically calculating the maximum processing limit of the server and the access frequency of the client. In practical application, the access frequencies of different clients are usually different, so that the dynamic current limit obtained by dynamic calculation is usually different according to the maximum processing limit of the server and the access frequency of the client among different clients; and even for the same client, the dynamic limit of the client will also be dynamically changed, since the access frequency of the client will typically be different at different times.
In practical applications, the method provided in the embodiments of the present application may calculate the dynamic current limit, for example, after determining the access frequency of the client in step S11, the maximum processing limit of the server may be further obtained, where the maximum processing limit of the server may specifically be the maximum number of access requests that the server can process in a preset time period, and if the number of access requests that the server needs to process exceeds the maximum processing limit, blocking or even downtime of the server is easily caused, and in general, the maximum processing limit of the server may be calculated through performance parameters and current load of the server; after obtaining the maximum processing limit of the server and the access frequency of the client, the dynamic current limit may be further calculated according to the maximum processing limit of the server and the access frequency of the client, for example, the maximum processing limit and the access frequency may be substituted into a dynamic current limit calculation formula, so as to calculate the dynamic current limit.
In addition, a preset threshold may be set, after the access frequency of the client is determined in the step S11, whether the access frequency is greater than the preset threshold may be determined, if yes, it is indicated that current limiting is required by the method provided in the embodiment of the present application, and then the dynamic current limit is calculated according to the maximum processing limit of the server and the access frequency of the client only if the access frequency of the client is greater than the preset threshold, where the preset threshold is smaller than the dynamic current limit. Of course, if the access frequency is determined to be less than or equal to the preset threshold, it is indicated that the method provided by the embodiment of the present application is not required to perform current limiting on the client, so that the dynamic current limiting unit is not required to be calculated according to the maximum processing unit of the server and the access frequency of the client.
In practical applications, the dynamic current limit calculation formula may be various, for example, the dynamic current limit calculation formula may be a dynamic current limit calculation formula as shown in formula one:
in the formula I, L is the calculated dynamic current limit; m is the maximum processing limit of the server; f (f) 1 The access frequency of the client; k (k) 1 Amplifying the coefficient for the access frequency; a is a resource allocation coefficient used to characterize the importance level of a client.
For the access frequency amplification factor k in equation one 1 The size of the gateway device may be generally set according to actual needs, for example, when the total amount of access requests received by the gateway device in a preset time period is greater than the overall preset upper limit value of each client, or when the access frequency of the client is too high (greater than the preset upper limit value of a single client)The k can be 1 Larger than this, e.g. selecting the k from the interval of (1, 10) 1 Thereby amplifying the influence of the access frequency of the client on the dynamic current limit; conversely, when the total amount of access requests received by the gateway device in the preset time period is smaller than the overall preset upper limit value, and the access frequency of the client is smaller than the preset upper limit value of the single client, the k can be calculated 1 The setting being relatively small, e.g. the k is selected from the interval of (0, 1) 1 Is a value of (2).
A in the formula one is a resource allocation coefficient, which is a resource allocation coefficient for representing the importance level of the client. In practical applications, the clients are generally of multiple types, for example, for taxi taking software, there are driver clients, passenger clients and the like, and the importance levels of the clients of different types are generally different, so that the type of the client can be determined first, the type is associated with a corresponding importance level, and then a resource allocation coefficient table is queried according to the importance level of the client, so as to determine the resource allocation coefficient corresponding to the importance level of the client. The resource allocation coefficient table specifically describes the resource allocation coefficients corresponding to the clients with different importance levels. The value range of the resource allocation coefficient a is generally greater than 0 and less than 1.
Thus, the resource allocation coefficient a and the access frequency amplification coefficient k are obtained 1 Maximum processing limit M of server and access frequency f of client 1 And then substituting the dynamic current limit value into the formula I so as to calculate the dynamic current limit value of the client.
In the dynamic limit calculation formula shown in the formula one, the maximum processing limit M of the server and the access frequency f of the client are mainly used 1 And combines the client importance level and the access frequency magnification factor k 1 To comprehensively calculate and obtain the dynamic current limit of the client. In practical applications, the network status of the client is also one of the important factors affecting the dynamic limit of the client, so that the maximum processing limit of the server and the access of the client are determinedThe frequency may be used to calculate the dynamic current limit, or the network state score of the client may be determined first, and then the dynamic current limit may be calculated according to the maximum processing limit of the server, the network state score of the client, and the access frequency of the client, for example, the maximum processing limit of the server, the network state score of the client, and the access frequency of the client are substituted into the dynamic current limit calculation formula, so as to calculate the dynamic current limit.
The dynamic current limit calculation formula may be a dynamic current limit calculation formula shown in formula two:
the dynamic current limit calculation formula shown in the formula two may be referred to as a first dynamic current limit calculation formula. The difference between the formula two and the formula one is that the network state score b of the client is newly added in the formula two, and other parameters are the same as those of the formula one. The value range of the network state score b is generally greater than 0 and less than 1.
For the newly added network state score b of the client in the formula II, the network state score b can be generally determined by a method that the server firstly sends a network state detection signal to the client, for example, the server can periodically send the network state detection signal to the client in a heartbeat detection mode; and then determining the network state grade of the client according to the response time of the client to the network state detection signal, wherein generally speaking, the longer the response time is, the worse the network state of the client is, the shorter the response time is, the better the network state of the client is, so that the network state grade table can be queried by utilizing the response time, and the network state grade of the client is obtained, wherein in the network state grade table, the network state grade corresponding to each different response time is specifically recorded. After determining the network state grade of the client, the network state grade of the client is further utilized to query the network state scoring table, so that the network state score of the client is determined. The network state scoring table is recorded with network state scoring tables corresponding to different network state grades respectively.
Thus, the network state score b of the client is obtained, and the resource allocation coefficient a and the access frequency amplification coefficient k are obtained 1 Maximum processing limit M of server and access frequency f of client 1 And then substituting the dynamic current limit value into the formula II so as to calculate the dynamic current limit value of the client.
It should be noted that, in the dynamic current limit calculation formula shown in the formula two, compared with the dynamic current limit calculation formula shown in the formula one, the newly added parameter is the network state score b of the client, and in practical application, when the network state of the client is better, for example, the network state grade of the client is higher, the network state score b of the client may not be considered, so that the dynamic current limit of the client is calculated by adopting the dynamic current limit calculation formula shown in the formula one; when the network state of the client is poor, for example, the network state level of the client is low, even if a higher dynamic current limit is allocated to the client, the network state of the client is poor, which may cause resource waste, so that the dynamic current limit calculation formula shown in the formula two can be adopted to calculate the dynamic current limit of the client, that is, the formula one or the formula two can be determined and selected according to the network state level of the client and used as the dynamic current limit calculation formula to calculate the dynamic current limit of the client.
It should be further noted that, in practical applications, in addition to considering the network status of the client, in some cases, it may be necessary to consider the accumulation of the request frequency of the client for a period of time, so as to comprehensively determine the dynamic current limit of the client.
The dynamic current limit calculation formula may be a dynamic current limit calculation formula shown in formula three (the dynamic current limit calculation formula shown in formula three may be referred to as a second dynamic current limit calculation formula):
in the formula III, L is the calculated dynamic current limit; m is the maximum processing limit of the server; a is a resource allocation coefficient used for representing the importance level of the client; b is the network state grading of the client; f (f) i K is the access frequency of the client in the ith period i The access frequency amplification factor of the ith period is i=1, and the access frequency amplification factor k in the above formula two and formula one can be obtained 1 And the access frequency f of the client 1 The method comprises the steps of carrying out a first treatment on the surface of the n is the number of accumulated periods, and the value of n can be 5, 6 or 7, so that the access frequency f in n preset time periods i Multiplied by the access frequency amplification factor k respectively i And accumulate.
For example, the above-mentioned access frequency of the client may be the number of times the client transmits the access request to the server in a preset period of time, for example, the preset period of time may be 30 minutes, where the number of times of the access request in 30 minutes is taken as the access frequency f 1 The corresponding access frequency amplification factor is k 1 The method comprises the steps of carrying out a first treatment on the surface of the At this time, the preset time period, that is, 30 minutes is taken as one period, and then 30 minutes before the preset time period is taken as the previous period, and the number of access requests of the previous period is obtained as the access frequency f 2 The corresponding access frequency amplification factor is k 2 And the like, the access frequency f of the client in the ith period can be obtained i And its corresponding access frequency amplification factor is k i 。
Wherein, since the time accumulation effect is reduced from the first period (i=1) to the nth period, the access frequency amplification factor of the latter period can be 0 of the previous access frequency amplification factor5 times, e.g. k 2 ＝0.5*k 1 、k 3 ＝0.5*k 2 、k 4 ＝0.5*k 3 ，…，k i ＝0.5 i-1 *k 1 ，…，k n ＝0.5 n-1 *k 1 This can obtain the access frequency amplification factor for each cycle.
In the third formula, the access frequency amplification coefficients of n periods are multiplied by the access frequency and then accumulated, so that the method is more suitable for the situation that the access frequency of the client is frequently changed compared with the situation that only the access frequency amplification coefficient and the access frequency of the first period are considered in the second formula. For example, the access frequency of a certain client is not stable, but changes frequently with time, and the dynamic current limit of the client can be calculated by using the formula three types.
Step S13: and limiting the current of the client under the condition that the access frequency is greater than the dynamic current limit.
After determining that the access frequency of the client is greater than the dynamic limit value unit in step S12, the client is limited in the case that the access frequency is greater than the dynamic limit value unit, and the limiting mode includes rejecting the access request sent by the client, or sending a limiting prompt message to the client, so as to prompt the user of the client to limit the current. Of course, if the access frequency of the client is determined to be less than or equal to the dynamic limit, it is not necessary to limit the current by multiple clients.
The access flow limiting method of the server provided by the embodiment of the application comprises the steps of determining the access frequency of a client, judging whether the access frequency of the client is larger than the dynamic flow limiting limit, and limiting the flow of the client under the condition that the access frequency is larger than the dynamic flow limiting limit.
