Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
The embodiment of the invention provides a request limiting method, a request limiting device and a computer readable storage medium. Wherein the request restriction means may be integrated in the electronic device, which may be a server.
The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, big data and an artificial intelligence platform.
The client may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart watch, a smart device, and the like. For the specific type of the client, the user may set the client according to actual conditions, which is not limited herein.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
The request limiting method provided in the embodiments of the present application is described in detail below.
As shown in fig. 1, the specific flow of the request restriction method is as follows:
s101, obtaining the access request quantity of the page.
In some promotional activities (a promotional activity refers to an activity of robbing a preset object at a specified time, the object may refer to a commodity or may refer to a red envelope). Therefore, when the user enters the page corresponding to the promotion activity, the server can obtain the access request amount of the page corresponding to the promotion activity.
It should be understood that the client may obtain the access request amount of the page in real time and then periodically send the page access request amount to the server, so that the server may obtain the access request amount of the page. Alternatively, the Content Delivery Network (CDN) may obtain the access request amount of the page in real time, and then periodically send the page access request amount to the server, so that the server may obtain the access request amount of the page. For the way of obtaining the access request amount of the page by the server, the user may select the access request amount according to the actual situation, and the application is not specifically limited herein.
The access request amount of the page refers to the number of users entering the page corresponding to the promotion activity in a preset time period before the promotion activity starts, namely the number of users waiting for promotion. For example, if the promotional activity start time is 10 minutes at A hour, the access request amount for a page may refer to the number of users who entered the page corresponding to the promotional activity from A hour to 9 minutes and 59 seconds at A hour.
And S102, when the access request quantity meets the preset flow limiting condition, determining the flow limiting value of the server according to the access request quantity.
After the server acquires the access request quantity, whether the access request quantity meets the preset current limiting condition can be determined. When the access request quantity meets the preset flow limiting condition, the number of people waiting for participating in the promotion activity is larger, which means that the number of people about to participate in the promotion activity is larger. Therefore, at this time, the traffic limit value of the server can be determined according to the access request amount.
The process of determining the flow limit value of the server according to the access request amount may be: and substituting the access request quantity into a preset formula by the server for calculation so as to obtain the flow limiting value of the server. Alternatively, the following may be used: and the server searches the flow limiting value of the server corresponding to the access request amount from a preset mapping table. For the specific manner of determining the flow limit value of the server according to the access request amount, the user may select according to the actual situation, and this embodiment is not limited herein.
The preset current limiting condition may be set by a user according to an actual situation, for example, in this embodiment, the preset current limiting condition is that the access request amount in a preset time interval is greater than a time threshold or a change rate of the access request amount is greater than a preset value. The present application is not specifically limited herein.
S103, limiting the user request initiated by the page exceeding the flow limiting value by utilizing the content distribution network node.
After obtaining the current limit value, the server may send the current limit value directly to the content distribution network node. The content distribution network node thus receives the restriction value. Or, the server may also generate a preset instruction according to the current limiting value, and send the preset instruction to the content distribution network node, and the content distribution network node analyzes the preset instruction, so as to obtain the current limiting value.
It should be noted that the server may send the restriction value to each content distribution network node on average, for example, if the restriction value is 1000, and there are 10 content distribution network nodes, the sub-restriction value corresponding to each content distribution network node is 100.
Alternatively, the server may determine the sub-restriction value corresponding to the content distribution network node according to the performance parameter of the content distribution network node.
The content distribution network node, after obtaining the current limit value, will initiate a user request for the page when the start time of the promotional program is reached. When the user request initiated for the page exceeds the current limit value, the content distribution network node will limit the user requests that exceed the current limit value.
Wherein, when the promotion activity is the activity of preempting the goods, the user request may be a purchase request initiated by the user for the page. Alternatively, when the promotional activity is a red envelope robbing, the user request may also be a red envelope robbing request initiated by the user for the page.
The limitation refers to that the content distribution network node intercepts the user request for finding the current limiting value, so that the server cannot receive the user request exceeding the current limiting value, and further cannot receive a large number of user requests in a short time.
The content distribution network nodes refer to node servers distributed in different areas, when a user initiates a request at a client, the request is sent to the content distribution network node closest to the client, and if the content distribution network node has a resource corresponding to the request, the resource corresponding to the request is returned to the client, so that the user can quickly acquire the resource corresponding to the request.
As can be seen from the above, in the embodiment of the present application, the access request amount of the page is obtained first. And then when the access request quantity meets the preset current limiting condition, determining the current limiting value of the server according to the access request quantity. And finally, the content distribution network node is used for limiting the user requests which exceed the flow limiting value and are initiated aiming at the page, so that the user requests which exceed the flow limiting value and are initiated aiming at the page cannot reach the server, and the server cannot be down.
In some embodiments, the specific process of restricting the user request for page initiation that exceeds the current limit value by the content distribution network node may be: and the server sends the flow limiting value to the content distribution network node, and the content distribution network node limits the user request initiated by the page and exceeding the flow limiting value after receiving the flow limiting value.
Because the performance of each content distribution network node is different, the flow limiting values corresponding to different content distribution network nodes can be different. Therefore, in some possible implementation manners, after determining the throttling value of the server, the server may obtain the performance parameter of each content distribution network node, and then determine the sub-throttling value corresponding to each content distribution network node according to each performance parameter and the throttling value. And finally, when the user request initiated aiming at the page exceeds the sub-restriction value corresponding to the content distribution network node, limiting the user request exceeding the sub-restriction value by using the content distribution network node.
The sum of the sub-restriction values corresponding to each content distribution network node is equal to the restriction value of the server. Therefore, after each content distribution network node intercepts the user request exceeding the sub-restriction value corresponding to the content distribution network node, the user request exceeding the restriction value can not reach the server finally.
For example, referring to fig. 2, the restriction value is 100, there are 4 content distribution network nodes, the number of sub-restriction values corresponding to the content distribution network node 1 is determined to be 30 according to the performance parameter of the content distribution network node 1, the number of sub-restriction values corresponding to the content distribution network node 2 is determined to be 10 according to the performance parameter of the content distribution network node 2, the number of sub-restriction values corresponding to the content distribution network node 3 is determined to be 20 according to the performance parameter of the content distribution network node 3, and the number of sub-restriction values corresponding to the content distribution network node 4 is determined to be 40 according to the performance parameter of the content distribution network node 4.
The content distribution network node 1 restricts the 31 st user request by a user request within 30. The content distribution network node 2 limits the 11 th user request by a user request within 10. The content distribution network node 3 limits the 21 st user request by a user request within 20. The content distribution network node 4 limits the 41 st user request by user requests within 40 so that user requests exceeding the restriction value 100, i.e. 101 st user requests, do not reach the server.
The performance parameters of the content distribution network node include, but are not limited to, a utilization rate of a Central Processing Unit (CPU) of the content distribution network node, a bandwidth of the content distribution network node, and the like.
After the content distribution network node receives the flow limit value, when a user initiates a user request for a page, the content distribution network node forwards a target user request initiated for the page within the flow limit value to a server, and the server receives the user request. The server then determines the target number in the target user request. If the target number is less than or equal to the inventory amount, the inventory amount is decremented based on the target number, and a virtual resource transfer operation is performed.
The target number is the number of objects corresponding to the promotion desired by the user. For example, when the sales promotion activity is a first-time commodity purchasing activity, the object corresponding to the sales promotion activity is a commodity, and the target quantity may be the quantity of commodities purchased by the user. When the promotion activity is a red envelope robbing activity, the object corresponding to the promotion activity is a red envelope, and the target quantity can be the amount of money randomly matched for the user request when the user initiates the user request at the client.
Virtual resources refer to monetary assets that exist in electronic form, such as money that a user spends on a credit card or a payment instrument. The virtual resource transfer operation refers to transferring money from the user's account to the merchant's account or the third party platform's account, or transferring money from the merchant's account or the third party platform's account to the user's account.
In addition, the server can also return the relevant result information to the client. For example, when a user requests that the flow limit value be exceeded, information that the promotional program has ended may be returned to the client. And when the user request is within the flow limit value, if the target quantity is greater than the inventory quantity, returning the information that the promotion activity is finished to the client, and if the target quantity is less than or equal to the inventory quantity, returning the information that the promotion activity is successfully robbed to the client.
In other embodiments, when the access request amount satisfies the preset current limit condition, determining a current limit value of the server according to the access request amount includes: when the number of access requests is greater than the threshold, a first time of a first one of the number of access requests and a second time of a last one of the number of access requests are determined. A difference between the first time and the second time is determined. And if the difference is smaller than or equal to the preset time value, determining the flow limit value of the server according to the access request quantity.
For example, the threshold is 1000, and when the access request amount is 1001, a first time of a first access request of the 1001 access requests and a last access request of the 1001 access requests, that is, a second time of the 1001 access request, are determined, and then the first time and the second time are subtracted to obtain a difference. And if the difference value is less than or equal to the preset time value, determining the flow limit value of the server according to the access request quantity.
The first time refers to the time when the server receives the first access request, and the second time refers to the time when the server receives the last access request.
In other embodiments, the server may preset a mapping table between the access request amount and the current limiting value, and then obtain the preset mapping table when the access request amount satisfies the preset current limiting condition. And finally, searching the flow limiting value of the server corresponding to the access request amount from a preset mapping table. Optionally, the process of searching the flow limiting value of the server corresponding to the access request amount from the preset mapping table may be:
and comparing the access request quantity with the preset request quantity in the preset mapping table, finding out the preset request quantity which is the same as the access request quantity, and searching for the flow limiting value corresponding to the preset request quantity which is the same as the access request quantity.
Alternatively, the following may be used: and searching a target request quantity interval corresponding to the access request quantity in a preset mapping table, and then finding out a flow limit value corresponding to the target request quantity interval, namely at the moment, storing the request quantity interval and the flow limit value in the preset mapping table correspondingly.
Referring to fig. 3(M and N are integers and greater than 1. content distribution network nodes 1-N represent content distribution network nodes 1 to N, and there are N total content distribution network nodes, and similarly, clients 1-M represent clients 1 to M, and there are M total clients), a specific application scenario of the request restriction method provided in the embodiment of the present application is described below.
10 minutes before the second commodity killing activity starts, when a user clicks a link of the second commodity killing activity, a client generates an access request of a page of the second commodity killing activity according to the link and sends the access request to a content distribution network node, the content distribution network returns relevant information of the page of the second commodity activity to the client, the client accordingly enters the page of the second commodity killing activity, and the content distribution network node acquires the number of the users entering the page, namely the access request amount of the page in real time and periodically sends the access request amount of the page to a server. The server judges whether the access request amount is greater than 100, if the access request amount is greater than 100, the first time of the first access request and the second time of the last access request in the access request amount are determined, and if the difference value of the first time and the second time is less than or equal to 1 minute, the flow limiting value corresponding to the access request amount is searched from a preset mapping table.
The method comprises the steps of obtaining performance parameters of each content distribution network node, determining a sub-restriction value corresponding to each content distribution network node according to the performance parameters and the restriction values of each content distribution network node, and sending the sub-restriction value corresponding to each content distribution network node.
When the activity of killing commodities in seconds starts, a user initiates a commodity purchasing request on the page through the client, the content distribution network node forwards the commodity purchasing request within the sub-flow limit value to the server, the server checks the quantity of the commodity purchasing request within the sub-flow limit value, if the quantity is less than or equal to the inventory quantity, the inventory quantity is deducted, money corresponding to the commodity purchasing request in the account of the user is transferred to the account of the third-party platform, a message of successful purchasing is returned to the content distribution network node, and the content distribution network node returns the message of successful purchasing to the client.
And the content distribution network node intercepts the commodity purchasing request exceeding the sub-restricted flow value and returns the information of the end of the second commodity killing activity to the client.
Another method for requesting restriction provided by the present application is described in detail below.
Referring to fig. 4, the request limiting method is applied to a content distribution network node, and the specific flow is as follows:
s401, obtaining the user request quantity.
The user request amount is the number of user requests initiated by the user for the page. When a user initiates a user request on a page of a promotion activity, a client sends the user request to a content distribution network node, and the content distribution network node counts the received user request, so that the user request amount is obtained.
S402, when the user request quantity exceeds the flow limit value, limiting the original user request exceeding the flow limit value in the user request quantity.
The restriction value may be a pre-stored value in the content distribution network node. The user can directly set on the content distribution network node, and the content distribution network node stores the content. Or, the server may set in real time according to the access request amount of the page, and then send the set flow limiting value to the content distribution network node, and the content distribution network node stores the flow limiting value.
After the content distribution network node obtains the user request quantity, if the user request quantity exceeds the flow limit value, limiting the original user request which exceeds the flow limit value in the user request quantity, and forwarding the user request which is within the flow limit value in the user request quantity to the server.
In this embodiment, the content network node stores a flow limit value, and when the user request amount exceeds the flow limit value, the original user request for finding the flow limit value in the user request amount is limited, so that the original user request exceeding the flow limit value does not reach the server, and the server does not receive a large number of user requests in a short time, thereby preventing the server from being down.
For other realizations of the request limiting method in this embodiment, reference may be made to the request limiting method in the foregoing embodiment, and this implementation is not described herein again.
