Example 1
Please refer to fig. 2, which is a flowchart illustrating a method for controlling access to a page resource according to an exemplary embodiment of the present disclosure, including the following steps:
step S1: receiving a URL link request of private page resources, and acquiring the request time of the URL link request.
The private page resource is a page resource set by a resource owner and used in a limited right and/or a limited time, wherein the page resource may include but is not limited to: pictures, text, files, applications, etc. Specifically, the URL link obtained each time the private page resource is requested to be obtained generally has timeliness, and if the time for requesting to obtain the private page resource exceeds the timeliness of the URL link, the private page resource cannot be obtained through the URL link, and a new URL link needs to be obtained again; and if the time for requesting to acquire the private page resource does not exceed the time limit of the URL link, acquiring the private page resource through the URL link.
The URL link request of the private page resource may include a download address of the private page resource and a request time of the URL link request. The download address of the private page resource usually carries an identifier (objectkey) of the private page resource to uniquely identify the private page resource.
In the embodiment of the disclosure, when a user opens a webpage through a browser of a client, access to a private page resource in the webpage is triggered, at this time, the client sends a URL link request of the private page resource to a URL issue server, so as to obtain a corresponding private page resource locally at a CDN server or the client, and display the private page resource in the client. And after receiving a URL link request of the private page resource sent by the client, the URL issuing server acquires a download address of the private page resource and the request time of the URL link request from the URL link request of the private page resource, and then calculates and acquires the URL link.
Step S2: acquiring a preset time interval corresponding to the request time; wherein, each private page resource corresponds to at least two continuous preset time intervals.
The preset time interval is a plurality of time intervals with equal length, which are formed by dividing the time of one day, and the length of the time interval can be set according to needs, for example, the time interval is set to be 1 hour or 2 hours. In order to conveniently obtain the private page resources, each private page resource corresponds to at least two continuous preset time intervals. In the embodiment of the present disclosure, a day is divided into 24 preset time intervals with a time length of 1 hour, where the 24 preset time intervals are, in order, Period1 ═ 0, 1], (Period 2 ═ 1, 2], (Period 3 ═ 2, 3], (… Period24 ═ 23, 24 ]. if the request time is 2 hours and 15 minutes, the corresponding preset time interval Period3 ═ 2, 3.
Step S3: generating a timestamp of the URL link request according to the preset time interval; the timestamps corresponding to the same preset time interval are the same, and the timestamps corresponding to the non-same preset time intervals are different.
The step of generating the timestamp of the URL link request according to the preset time interval includes:
and acquiring the expiration time length of the private page resource, and adding the maximum time value of the preset time interval and the expiration time length of the private page resource to generate a time stamp of the URL link request. In the embodiment of the disclosure, according to the fact that the timestamps corresponding to the same preset time interval are the same, and the timestamps corresponding to the non-same preset time intervals are different, not only can a user repeatedly access the same private page resource in a short time, but also the private page resource can be quickly obtained from a local cache, and can have certain security and confidentiality. For example, please refer to fig. 3 and 4, the request times of the URL link requests of the private page resources are T1, T2, T3, T4, T5, T6, and T7, respectively, the preset time intervals corresponding to T1, T2, T3, T4, and T5 are Period1, the preset time intervals corresponding to T5, T6, and T7 are Period2, and if the expiration time length of the private page resource is ExpiredIn, when the request is initiated at T1 time, the URL issuing server calculates the obtained timestamp to be the maximum time value + ExpiredIn of Period1 ═ Period 1; when a request is initiated at time T2, the URL issuing server calculates that the obtained timestamp is maximum time value + ExpriedIn of Period1 of timestamp 2; when a request is initiated at time T3, the URL issuing server calculates that the obtained timestamp is maximum time value + ExpriedIn of Period1 of timestamp 3; when a request is initiated at time T4, the URL issuing server calculates that the obtained timestamp is maximum time value + ExpriedIn of Period1 of timestamp 4; when a request is initiated at time T5, the URL issuing server calculates that the obtained timestamp is maximum time value + ExpriedIn of Period2 of timestamp 5; when a request is initiated at time T6, the URL issuing server calculates that the obtained timestamp is maximum time value + ExpriedIn of Period2 of timestamp 6; when a request is initiated at time T7, the URL issuing server calculates the obtained timestamp as maximum time value + ExpriedIn of Period2 of timestamp 7. The time stamps from T1 to T4 have equal values, so that the URLs used by the clients are the same, the clients use the same URL to initiate calls in different time, cached files can be used locally without initiating HTTP requests, and therefore the private page resources can be obtained quickly. In the following description, a specific example is given, where the preset time interval is (2, 3), and the expiration time length of the private page resource is 2 hours, the time stamp of the URL link request is 3+ 2-5, that is, the time stamp of the URL link request is 5 times of the URL link request time, and where the preset time interval is (23, 24), and the expiration time length of the private page resource is 2 hours, the time stamp of the URL link request is 24+ 2-26, that is, the time stamp of the URL link request is 2 times of the next day of the URL link request time.
In the embodiment of the present disclosure, a preset time interval corresponding to the request time is obtained by the URL issuing server, and a timestamp of the URL link request is generated according to the preset time interval.
Step S4: generating a URL link containing the timestamp.
Wherein the URL link may include a download address that may include a private page resource and the timestamp. The download address of the private page resource usually carries an identifier (objectkey) of the private page resource to uniquely identify the private page resource. Specifically, the URL link is a link formed by splicing a download address of a private page resource and the timestamp, for example, the URL link is URL ═ https:// objectKeyt ═ timestamp, where "objectKey" is an identifier of the page resource, and "https:// objectKey? "is a download address carrying the identification of the private page resource, t is a key, and timestamp is a key value, i.e. the timestamp.
In the embodiment of the present disclosure, the URL link including the timestamp is generated by the URL issuing server according to the timestamp.
According to the method and the device, the preset time interval corresponding to the request time is obtained, and the timestamp of the URL link request is generated according to the preset time interval, so that when the same private page resource is repeatedly requested to be accessed in the preset time interval, the obtained URL links are the same, the private page resource needs to be requested to be obtained from the server except for the first time when the private page resource is requested to be accessed in the preset time interval, the private page resource can be quickly loaded from the local cache of the client according to the same URL link when the private page resource is requested to be accessed in other time, and the loading flow of the private page resource is effectively reduced. Furthermore, the URL link is calculated according to the preset time interval corresponding to the request time, and middleware such as Mysql or Redis does not need to be used for caching the URL link, so that the cost is reduced, and the cache loss is reduced.
In a preferred embodiment, after the generating the URL link containing the timestamp, the method further includes the following steps:
step S5: receiving an access request of the private page resource sent by the URL link, and acquiring the access request time of the private page resource; and comparing the access request time with the time stamp in the URL link, and if the access request time exceeds the time stamp in the URL link, sending overtime reminding information.
Further, if the access request time does not exceed the timestamp in the URL link, the private page resource is sent.
Referring to fig. 4, in the embodiment of the present disclosure, the generated URL link has timeliness, and the effective time of the generated URL link is a time period, specifically, a time stamp from the maximum time value of the last preset time interval closest to the preset time interval corresponding to the URL link.
By setting the timeliness of the URL link, the private page resource is prevented from being infinitely used for a long time, and the safety and the effectiveness of the private page resource are further realized.
In the embodiment of the disclosure, a user inputs a URL link at a client to send an access request of a private page resource to a CDN server; the CDN server receives an access request of the private page resource sent by the URL link and acquires access request time of the private page resource; comparing the access request time with the timestamp in the URL link, and if the access request time exceeds the timestamp in the URL link, sending overtime reminding information to a client; and if the access request time does not exceed the time stamp in the URL link, sending the private page resource to the client, so that the private page resource is displayed at the client.
