Abstract
The invention discloses a system for preventing a client from repeatedly requesting a server, which is characterized in that a request interceptor, a front-end buffer, a background monitor and an abnormal monitor are configured at the client; the request interceptor is used for intercepting all request information sent to the server by the client; the front-end buffer is used for storing ongoing request information; the background monitor is used for monitoring feedback information of the server to the request information; the exception listener is used for monitoring exception information fed back by the server. Therefore, the system for preventing the client from repeatedly sending the request to the server solves the problem that the foreground repeatedly sends the request to the server, judges and processes the repeated request at the client, reduces the workload of the server, and avoids the repeated request caused by network delay or misoperation. The invention also discloses a method for preventing the client from repeatedly requesting the server.
Description
Technical Field
The invention relates to the field of network communication, in particular to a system and a verification method for preventing a client from repeatedly requesting a server.
Background
At present, all aspects of production and life are not separated from a network, various software generally relates to data request and transmission between a server and a client, the client mainly makes a data request to the server, the server performs data extraction and processing after identity verification and then feeds back the data to the client, in the process, the client may make multiple times of same requests to the server due to factors such as misoperation or network delay, and if the servers perform processing one by one, the load of the server is increased, and on the other hand, if related requests relate to related actions, data confusion may be caused.
Therefore, the request sent from the client to the server needs to be subjected to secondary authentication besides authentication, so that unnecessary repeated requests are filtered.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: an authentication method for preventing a client from repeatedly requesting a server.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a system for preventing repeated requests from a client to a server, comprising: configuring a request interceptor, a front-end buffer, a background monitor and an exception monitor at a client;
the request interceptor is used for intercepting all request information sent to the server by the client;
the front-end buffer is used for storing ongoing request information;
the background monitor is used for monitoring feedback information of the server to the request information;
the abnormity monitor is used for monitoring abnormity information fed back by the server;
compared with the prior art, the invention has the following technical effects:
the invention solves the problem that the foreground repeatedly sends the request to the server, judges and processes the repeated request at the client, reduces the workload of the server and avoids the repeated request caused by network delay or misoperation.
Based on the system, the verification process comprises the following steps:
s1, the client side initiates a request A;
s2, the request interceptor intercepts the A request and inquires whether the A request exists in the front-end buffer; if the request A exists in the front-end buffer, the current initiated request A is cancelled, otherwise, the step S3 is executed;
s3, storing the request A into a front-end buffer, and sending the request A to a server;
s4, the server processes the request A, and the server feeds back a request result to the client after successfully processing the request A;
s5, the background listener continues to listen until the action of the server feeding back the request result to the client? If yes, go to step S6, otherwise continue to go to step S5;
and S6, after delaying the set time T, deleting the request A in the front-end buffer.
Compared with the prior art, the invention has the following technical effects:
the invention solves the problem that the foreground repeatedly sends the request to the server, judges and processes the repeated request at the client, reduces the workload of the server and avoids the repeated request caused by network delay or misoperation.
On the basis of the technical scheme, the invention can be further improved as follows.
Preferably, the request interceptor comprises an error handling program, wherein the error handling program comprises a step of resetting a front-end cache.
The method has the advantages that when unexpected faults occur in the operation process of the request interceptor, the preset error processing program is entered, and the step of resetting the content in the front-end cache is set in the error processing program, so that even after the unexpected faults occur, the subsequent request information initiation of the client to the server is not influenced after the system is restarted, and the initiation of the next normal request is not delayed due to the setting of the request interceptor.
Drawings
FIG. 1 is a schematic diagram of a system for preventing repeated requests from a client to a server according to the present invention;
fig. 2 is a flowchart of an authentication method for preventing a client from repeatedly requesting a server according to the present invention.
Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
Fig. 1 is a schematic structural diagram of an authentication method for preventing a client from repeatedly requesting a server according to the present invention. An authentication method for preventing a client from repeatedly requesting a server, comprising: configuring a request interceptor 1-2, a front-end buffer 1-3 and a background monitor 1-4 at a client 1;
the request interceptor is used for intercepting all request information which is initiated by the client-side initiating request module to the server;
the front-end buffer is used for storing ongoing request information;
the background monitor is used for monitoring feedback information of the server to the request information;
the abnormity monitor is used for monitoring abnormity information fed back by the server;
as shown in fig. 2, the process of the client sending the a request to the server is as follows:
s1, the client side initiates a request A;
s2, the request interceptor intercepts the A request and inquires whether the A request exists in the front-end buffer; if the request A exists in the front-end buffer, the current initiated request A is cancelled, otherwise, the step S3 is executed;
s3, storing the request A into a front-end buffer, and sending the request A to a server;
s4, the server processes the request A, and the server feeds back a request result to the client after successfully processing the request A;
s5, the background listener continues to listen until the action of the server feeding back the request result to the client? If yes, go to step S6, otherwise continue to go to step S5;
and S6, after delaying the set time T, deleting the request A in the front-end buffer.
For example, the number of requests initiated by the client is 50, assuming that the current inventory number is 100, the client issues an inventory-out command, the number of the requests is 50, and the inventory number is changed to 50 after the inventory-out is normally completed. If the user performs misoperation at this time, the client continuously clicks twice warehouse-out, two identical instructions are issued by the client at this time, and if the server sequentially processes the instructions, two warehouse-out are actually performed, so that the inventory number at this time becomes 0.
If the problem is not great only with a single ex-warehouse service, the data can be recovered, but if the ex-warehouse action binds other services, such as order completion, work order completion and other series of service logics, the whole service flow is fatal at the moment and is difficult to recover, so that the effective avoidance of misoperation is very critical.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
