With continued reference to FIG. 1, memory 1005 of FIG. 1, which is one type of readable computer readable storage medium, may include an operating system, a network communication module, an application program module, and a dynamic update lifetime program. In fig. 1, the network communication module is mainly used for connecting to a server and performing data communication with the server; the processor 1001 may call the dynamic update duration program stored in the memory 1005 and execute the method for dynamically updating the duration provided by the embodiment of the present invention.
The embodiment of the invention provides a method for dynamically updating a duration.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a method for dynamically updating a duration according to the present invention.
In this embodiment, the method for dynamically updating duration is applied to a device for dynamically updating duration, and the method includes:
step S101, after receiving a request initiated by a client, any interface determines a target interface and records the current time point;
any interface described in this embodiment may be any one of a plurality of interfaces provided by a website, an application program, and the like. For example, a website set by a bank includes a login interface, an authentication interface, an inquiry interface, a transfer interface, a payment interface, and the like. The request in this embodiment corresponds to the interface, that is, the request may include a login request and an authentication request. The client comprises intelligent interaction equipment such as a computer and a mobile terminal, wherein the mobile terminal comprises a mobile phone, an ipad, a notebook computer and the like.
Generally, a request is generated through a client based on the interactive operation of a user, and the request is sent to a dynamic update duration device, after receiving the request sent by the client, the dynamic update duration device determines a target interface for sending the request and records a current time point, wherein the target interface is one of the arbitrary interfaces.
Step S102, determining the validity of the request based on the current time point and the valid duration of the target interface;
the request includes a cookie uploaded by the client, where the cookie is a small text file saved on the client by the server (the content in the cookie is typically encrypted), and the cookie may also contain relevant user information. That is, the cookie is a short piece of text that the server stores on the local machine and also sends the cookie previously returned by the server when the client sends a request to the server. And the Cookie stores the original duration of the client, and after the original duration is obtained based on the Cookie, the effective duration is determined based on the modification time of the Cookie and the original duration, wherein the effective duration is equal to the sum of the modification time and the original duration.
After the effective duration is determined, judging whether the current time is within the effective duration, and if the current time is within the effective duration, judging that the request is effective; otherwise, if the current time is not within the valid duration, the request is determined to be invalid.
Step S103, the request is valid, the duration of the target interface is determined based on a preset dynamic updating process, and the duration is returned to the client.
In this embodiment, in order to flexibly adjust the duration of the duration and meet the duration requirements of various interfaces, a dynamic update process is preset. It can be understood that the editing time consumption of the corresponding pages of different interfaces is different, the security requirements of different interfaces are also different, and the access frequencies of different interfaces are also different, for example, the time consumption for logging in an interface is longer than that for verifying an interface, and the security requirement for a payment interface is higher than that for querying an interface. If all the interfaces are set to have the same duration, the requirements of each interface are difficult to meet. Thus, a scheme for dynamically updating the duration is needed.
Specifically, a request record stored in a database is queried; in this embodiment, the dynamic update duration device generates a corresponding history request record each time after receiving a request sent by the client, and stores the history request record in the database. The historical request record includes a request time, a time interval of a last request corresponding to the request. Where the last request may be a request made by any client to any interface. For example, if the system includes A, B, C, D four interfaces, and interface a receives a request 1 sent by a certain client at a certain historical time, then records a request time 1 of the request 1, and determines a corresponding time interval of the previous request according to the request time 1 and the request time 0 based on a request time 0 of the previous request (for example, indicated as request 0) of the request 1, where the time interval is a difference between the request time 1 and the request time 0. And marking the time interval and the request time as historical request records and storing the historical request records in a database.
The historical request record of the target interface does not exist in the request record, and the duration of the target interface is set as a specified duration; if there is no history request record of the target interface, the target interface may be a new interface accessed for the first time, or the administrator clears the corresponding request record, so that the specified duration may be determined as the duration, where the specified duration is set as needed, for example, the specified duration is set to 15min, 20min, 30min, and the like.
And the request records comprise historical request records of the target interface, time intervals in the historical request records are obtained, and the duration of the target interface is determined according to a preset dynamic updating process based on the time intervals. If the historical request record of the target interface exists, it indicates that data for determining the duration according to a preset dynamic update process exists, so that the time interval in the historical request record is obtained, and the duration of the target interface is determined according to the preset dynamic update process based on the time interval. The time intervals in the history request record may be more than three or even a large number.
Specifically, a historical time interval queue of the target interface is obtained from the historical request record, and a time interval from the time when the target interface is accessed to the next time when any interface is accessed is marked as a new time interval of the target interface;
generally, since the system generally performs the initialization process, and the history request records before and after initialization are generally saved as two files, the time interval can be divided into the history time interval and the new time interval by taking the initialization time point as a boundary. The historical time interval is the time interval between each historical request received by the target interface before the initialization time point and the next request corresponding to each historical request received by any interface; the new time interval is a time interval between each history request received by the target interface after the initialization time point and a next request corresponding to each history request received by any interface.
Based on this, after receiving an interface request every time, recording a time interval between a current time point of the request and a last request time of a corresponding client access, wherein an interface accessed by the last request is the target interface. For generating a time interval queue based on the time interval.
For example, the time interval queue is represented by Q, and Q isixRepresenting the historical time interval of the i interface, i represents the interface number, x is the request sequence number, for example, the i interface is interface A, and the first time interval before (x-1) interface A before the system initialization time point can be respectively represented as QA1,QA2...QA(x-1)That is, the interface A has x-1 historical request records before the system initialization time point.
With QijAnd the time interval of sending the next request to any interface at the jth time of the ith interface after the system initialization time point is represented, wherein i is the number of the interface, and j is the number of times of sending the next request by a certain interface.
Assuming that a website system has only four interfaces a, B, C, D, and a client logs in interface a at 10:00 and then accesses interface B at 10:05, the first time interval of interface a is 10:05-10:00 ═ 5 minutes, i.e., QA1Recording the data into a database;
a client logs on to interface a at 11:00 and then accesses interface C at 10:01, the second first time interval of interface a is 11:01-11:00 ═ 1 minute, i.e., QA2Recording the data to a database;
a client logs on interface a at 10:00 and then accesses interface D at 10:10, the third first time interval of interface a is 10:10-10:00 ═ 10 minutes, i.e. QA3Recording the data to a database;
if a client accesses interface C at 10:01, followed by interface B at 10:08, the first time interval of interface C is 10:08-10:01 ═ 7 minutes, i.e. QC1Recording the data to a database;
a client accesses interface C at 10:08, followed by 10:09 and another interface C, the second first time interval of interface C is 10:09-10:08 ═ 1 minute, i.e., QC2Recording the data to a database;
the above is history request record, and the history time interval queue of each interface is obtained by initialization: qA,QB,QC,QDWherein Q isAQueue has 3 records, QBQueue has 0 records, QCQueue has 2 records, QDThe queue has 0 records.
After the website system is initialized, a client logs in an interface A at 10:00 and then accesses an interface B at 10:03, namely QijWhere i is interface A and j is the first new time interval of interface A, recorded as QA①。
And storing the new time interval into a new time interval queue, and determining the duration of the target interface based on the new time interval queue. In this embodiment, the interface a is determined as a target interface, and the historical time interval Q of the interface a is determinedA1、QA2、QA3And a new time interval QA①Adding to said time interval queue Q, i.e. said queue time interval Q comprises QA1、QA2、QA3、QA①。
The embodiment provides two ways of determining the duration of the target interface based on the time interval queue, where the first way is:
calculating the average interval and standard deviation of the time intervals in the time interval queue;
wherein the average interval is an average value of the time intervals, and the average interval is represented as μ, the calculation formula of the average interval is:
where n represents the number of time intervals.
The standard deviation θ is calculated as:
after determining the mean interval and the standard deviation, a triple standard deviation of 3 σ is determined based on a three sigma criterion. And determining the sum of the average interval and three times of standard deviation as the duration of the target interface.
The three sigma criterion is also called Lauda criterion, which is that firstly, a group of detection data is supposed to only contain random errors, the detection data is calculated to obtain standard deviation, an interval is determined according to a certain probability, the errors exceeding the interval are considered not to belong to the random errors but to be coarse errors, and the data containing the errors are rejected. Based on the three-sigma criterion, in the present embodiment, the probability of each time interval being distributed in (μ -3 σ, μ +3 σ) is 0.9974, and the probability of each time interval being distributed in (0, μ -3 σ) is 0.0013, and the total probability is 0.9987.
The second method comprises the following steps: sequencing all intervals in the time interval queue to obtain a sequencing result; determining an interval specifying a ranking as a duration of the target interface based on the ranking result. For example, the times are respectively sorted according to a rule from large to small, and a certain proportion of the data duration is taken. For example, the time queue is 100s, 99s, 98s, …, 2s, 1s, and if the duration of the first 5% ratio is taken as the duration, the duration 96s of the 5 th name is taken as the duration of the target interface.
Further, after the duration of the target interface is determined, comparing the duration with a maximum value and a minimum value of a preset duration, if the duration is greater than or equal to the minimum value and less than or equal to the maximum value, judging that the duration is an effective duration, and returning the duration to the client sending the request so that the client can store the duration in the cookie.
Further, after determining the validity of the request based on the current time point and the validity duration of the target interface, the method further includes:
the request is invalid, and prompt information of the request is sent out or a webpage corresponding to the request is logged out; it is understood that the request invalidation does not perform the corresponding request operation based on security considerations.
And if the request is valid, executing the operation corresponding to the request. For example, if the request is a query, a corresponding query result is returned to the client for the user to view.
Based on the scheme, after any interface receives a request initiated by a client, a target interface is determined and the current time point is recorded; determining validity of the request based on the current time point and the validity duration of the target interface; and the request is valid, the duration of the target interface is determined based on a preset dynamic updating process, and the duration is returned to the client. Therefore, the required duration of the effective request is re-determined based on the preset dynamic updating process, the flexible adjustment of the duration is realized, and the duration requirements of various interfaces are met.
