FIG. 2 illustrates a schematic structural diagram of a computer system suitable for use in implementing the electronic device of an embodiment of the present application.

It should be noted that the computer system 200 of the electronic device shown in fig. 2 is only an example, and should not bring any limitation to the functions and the scope of use of the embodiments of the present application.

As shown in fig. 2, the computer system 200 includes a Central Processing Unit (CPU)201 that can perform various appropriate actions and processes in accordance with a program stored in a Read Only Memory (ROM)202 or a program loaded from a storage section 208 into a Random Access Memory (RAM) 203.

With the development of e-commerce platforms, products are more and more popular, the number of corresponding users is more and more, and when a company releases new products or promotes activities, many companies can choose to carry out the new products on the own shopping malls of the company. However, there is typically no professional and powerful development team to develop and maintain a mall for some non-e-commerce or non-internet industry companies. That is, the general company's own mall is often unable to resist the high concurrency problems of new product release or promotion. Under the general condition, the solution idea of the problem is capacity expansion: bandwidth is increased, and servers are increased. However, this method causes a problem of high cost, and the improvement of this method for high complication is also limited.

Based on one or more of the problems discussed above, the present example embodiment provides a method of responding to a user request. The method for responding to the user request may be applied to the server 105, and may also be applied to one or more of the

terminal devices

101, 102, and 103, which is not particularly limited in this exemplary embodiment. Referring to fig. 3, the method of responding to the user request may include the following steps S310 to S340:

step S310: when a first user request is detected within a first preset time period, generating and outputting a verification image; the first user requests for electronic credentials that apply to a particular event.

Step S320: and if the first user input data aiming at the verification image is matched with the verification image, selecting the electronic certificate applied to the specific event from the preset electronic certificates and outputting the electronic certificate.

Step S330: when a second user request is detected within a second preset time period, matching the received second user input data with the electronic certificate; the second user request is for applying the electronic credential to a particular event, the first predetermined time period being disjoint from the second predetermined time period.

Step S340: and if the matching is successful, responding to the second user request according to the electronic certificate.

The above steps of the present exemplary embodiment will be described in more detail below.

In step S310, when a first user request is detected within a first preset time period, generating and outputting a verification image; the first user requests for electronic credentials that apply to a particular event.

The first preset time period may include an upper limit time (e.g., 8:00) and a lower limit time (e.g., 9:00), where the upper limit time and the lower limit time of the first preset time period are used to limit a range of the first preset time period, and the first preset time period may be a coupon code picking time period. In addition, the electronic certificate may be a character sequence, such as 5461423461234, 6 preferred 6 when limited 6, 201211546 limited time preferential, etc., and the electronic certificate may include chinese characters, english characters, or numbers, etc., which is not limited in the embodiments of the present application. In addition, the first user request detected in the first preset time period may be a request for obtaining a coupon code, and the specific event may be a request for purchasing a specific commodity, for example, the first user request may be used to obtain a coupon code applied to the specific commodity, and the electronic certificate may be the coupon code. It should be noted that, if the electronic voucher is a discount code, it can be applied to one or more specific commodities, for example, if the electronic voucher is a discount code whose milk powder category is full of 50 minus 25, it can be applied to purchase various brands of milk powder, if a user needs to purchase 20 yuan brand a milk powder, 20 yuan brand B milk powder and 10 yuan brand C milk powder, and if the above mentioned discount code whose milk powder category is full of 50 minus 25, brand a milk powder, brand B milk powder and brand C milk powder can be obtained through 25 yuan purchase. In addition, the verification image may include chinese characters, english characters, numbers, and the like, and the embodiment of the present application is not limited.

In this embodiment of the application, optionally, before generating and outputting the verification image when the first user request is detected within the first preset time period, the method may further include the following steps:

The identifier corresponding to the specific event can be represented by a figure, an image, a text and the like, and the identifier comprises an interactive state and a non-interactive state. For example, if the current time is 7: 00, the current time is not later than (i.e., earlier than) the upper limit time (e.g., 8:00) of the first preset time period (e.g., 8: 00-9: 00); if the current time is 8: and 10, the current time is later than the upper limit time (for example, 8:00) of the first preset time period (for example, 8: 00-9: 00).

Specifically, the manner of adjusting the current state of the identifier corresponding to the specific event to the interactive state may be: detecting whether the current state of the identifier corresponding to the specific event is an interactive state, and if so, executing the receiving of the first user request; if not, adjusting the current state to be an interactive state; the method specifically comprises the following steps: highlighting the identification corresponding to the specific event.

Similarly, the manner of adjusting the current state of the identifier to the non-interactive state may be: detecting whether the current state of the identifier corresponding to the specific event is an interactive state, if not, executing the detection whether the current time is later than the upper limit time of a first preset time period; if so, adjusting the current state to be a non-interactive state; the method specifically comprises the following steps: and performing gray scale representation on the identifier corresponding to the specific event. When the identifier is in the non-interactive state, the user cannot click the identifier through touch operation.

Therefore, by implementing the optional embodiment, the response to the user operation in the non-preset time period can be avoided through the interaction state adjustment of the identifier corresponding to the specific event, and the power consumption is reduced.

Further, after receiving the first user request, the method may further include:

The content distribution server is configured to load a first display page, where the first display page is used to display an activity corresponding to a specific event, and the activity may be a promotion activity, a full-reduction activity, or the like. For example, the specific event is a milk powder purchasing event, the activity corresponding to the milk powder purchasing event may be an activity of a specified brand of milk powder full 50 minus 25, and the first display page is used for displaying the activity of the specified brand of milk powder full 50 minus 25 for the milk powder purchasing event. In addition, the request time corresponding to the first user request may be the time when the client transmits the first user request to the server. Furthermore, since the prompt information is used to indicate that the electronic certificate applied to the specific event cannot be acquired, the prompt information may be, for example: if the activity of reducing the milk powder is not started, please pick up the preferential codes after the activity is started.

Specifically, the manner of requesting the content distribution server for the first presentation page corresponding to the specific event and outputting the first presentation page may be: a client sends a page request to a content distribution server; the content distribution server returns a first display page to the client; the client outputs the first display page.

Therefore, the optional embodiment can be implemented to respond to the user request in a preset time period, reduce the power consumption caused by the first user request in the non-preset time period and improve the processing efficiency of the server.

In this embodiment of the application, optionally, after generating and outputting the verification image, the method may further include the following steps:

Where the specific input area, which may be an input box typed by the user, does not intersect with the output area of the verification image, may detect a user operation (e.g., an input operation) and obtain data input by the user, i.e., first user input data, e.g., 123456.

Therefore, by implementing the optional embodiment, whether the identity of the user is a script can be verified through the verification image, so that the user can be prevented from carrying out abnormal preferential code pickup through the script to a certain extent.

In step S320, if it is detected that the first user input data for the verification image matches the verification image, an electronic certificate applied to a specific event is selected from the preset electronic certificates and output.

The preset electronic voucher can be a discount code, the discount code can be composed of characters such as Chinese characters, English characters and numbers, the number of the preset electronic vouchers can be multiple, and if the number of the preset electronic vouchers is multiple, the same two preset electronic vouchers do not exist in each preset electronic voucher.

In this embodiment of the application, optionally, before the verification image includes the verification character and the electronic certificate applied to the specific event is selected from the preset electronic certificates and output, the method may further include the following steps:

The verification characters can be the above-mentioned chinese characters, english characters, numbers, etc. The cache can be redis, and data in the cache is stored in a key value mode. Additionally, the user account also corresponds to the second user request.

Therefore, by implementing the optional embodiment, whether the data input by the user is matched with the verification image can be judged, and abnormal preferential code pickup of the user through the script is avoided.

Further, if it is detected that the electronic certificate corresponding to the user account and specific to the event exists in the cache, the method may further include the following steps:

The second display page is used for displaying the electronic certificate, the second display page may include a character sequence corresponding to the electronic certificate, and may further include information such as a two-dimensional code, a barcode, and a password corresponding to the electronic certificate. When a second user request is detected within a second preset time period, the received second user input data and the electronic certificate can be matched by verifying information such as a two-dimensional code, a bar code or a password corresponding to the electronic certificate. Therefore, the problem of overlong verification time caused by the fact that the user manually inputs the character sequences corresponding to the electronic certificates one by one can be solved, the data matching efficiency can be improved, and the response efficiency to the user request is improved.

Therefore, by implementing the optional embodiment, the electronic certificate can be displayed to the user through the interaction scheme of the second display page, and the use experience of the user is improved.

In this embodiment of the application, optionally, selecting and outputting an electronic certificate applied to a specific event from preset electronic certificates includes:

detecting whether a preset electronic certificate exists in the cache;

Wherein, if the preset electronic voucher does not exist in the cache, the method indicates that the discount code related to the specific commodity is picked up. In addition, after the electronic certificates applied to the specific events in the preset electronic certificates are deleted, the number of the preset electronic certificates is reduced by one.

Therefore, by implementing the optional embodiment, the uniqueness and the limitation of the preset electronic certificate can be ensured through a one-person-one-certificate system, and the electronic certificate is prevented from being falsely used by a user.

Further, if the preset electronic certificate does not exist in the cache, the method may further include the following steps:

The method for outputting the prompt information indicating that the preset electronic certificate is completely received may be: popping up prompt information for indicating that the preset electronic certificate is completely received in a pop-up window mode; or, the information content of the prompt message used for indicating that the preset electronic certificate has been completely received is displayed in a floating manner, which is not limited in the embodiment of the present application.

Therefore, by implementing the optional embodiment, the use experience of the user can be improved by timely informing the electronic certificate obtaining condition.

In this embodiment of the application, optionally, after selecting and outputting the electronic certificate applied to the specific event from the preset electronic certificates, the method may further include the following steps:

storing the user account and the electronic certificate in a key value structure (such as a key-value structure) in a cache; the key value structure is used for representing the binding relationship between the user account and the electronic certificate;

The user account is used as a key (the data type is set), and the electronic certificate is used as a value (the data type is hash) to form a key-value structure.

It can be seen that implementing this alternative embodiment, the query speed for data can be improved by key-value structure storage. In addition, the key value structure is persisted, so that the traceability of data can be ensured, and the request and response results of each user are public and transparent.

In step S330, when a second user request is detected within a second preset time period, matching the received second user input data with the electronic certificate; the second user request is for applying the electronic credential to a particular event, the first predetermined time period being disjoint from the second predetermined time period.

The first preset time period may be earlier than the second preset time period, for example, the first preset time period is 8: 00-9: 00, the second preset time period is 10: 00-11: 00, and 8: 00-9: 00 is earlier than 10: 00-11: 00 without intersection. The second preset period includes an upper limit time (e.g., 10:00) and a lower limit time (e.g., 11:00), and the upper limit time and the lower limit time of the second preset period are used to define a range of the second preset period, and the second preset period may be a commodity purchase period. In addition, the second user request detected within the second preset period may be a purchase request for a specific commodity, for example, the second user request is used for applying a coupon code to purchase the specific commodity. Additionally, the received user input data may be a sequence of characters, such as 5461423461234.

In this embodiment of the application, optionally, matching the received second user input data with the electronic certificate includes:

Wherein the same order bits may be the same position in the respective character sequences, e.g., the first character in a first character sequence (e.g., 123456) is the same order bits as the first character in a second character sequence (e.g., 123456). Therefore, the same sequence position of the characters in the first character sequence and the characters in the second character sequence is the same, that is, the first character in the first character sequence is the same as the first character in the second character sequence, the second character in the first character sequence is the same as the second character in the second character sequence, and the third character in the first character sequence is the same as the third character in the second character sequence.

Therefore, by implementing the optional embodiment, the data input by the user can be compared with the electronic certificate, so that the electronic certificate which the user needs to apply is real and credible, and the safety of the process of responding to the user request is improved.

In step S340, if the matching is successful, the second user request is responded according to the electronic certificate.

In this embodiment of the application, optionally, the step of responding to the second user request according to the electronic certificate, where the electronic certificate is a coupon code, and the specific event is a specific commodity purchase event, includes:

the specific goods purchase event is performed according to the goods price.

Specifically, the manner of determining the commodity price corresponding to the specific commodity purchase event according to the coupon code may be: the item price (e.g., 25 dollars) corresponding to the specific item purchase event is determined based on offer details (e.g., full 50 minus 25 dollars) corresponding to the offer code.

Therefore, by implementing the optional embodiment, the commodity price after the discount can be automatically determined through the discount condition, so that the use experience of the user is improved, and the use viscosity of the user is improved.

Therefore, by implementing the method for responding to the user request shown in fig. 3, the problem of high concurrency can be solved to a certain extent by processing different user requests at different time intervals, and the processing efficiency of the user request is improved. In addition, whether the identity of the user is the script or not can be verified through the verification image, so that the user can be prevented from carrying out abnormal electronic certificate obtaining through the script to a certain extent.

Referring to fig. 4, fig. 4 schematically illustrates a flow chart of a method of responding to a user request according to another embodiment of the present application. As shown in fig. 4, the method for responding to a user request of another embodiment may include steps S400 to S440, in which:

It should be noted that steps S400 to S440 correspond to the steps in fig. 3 and the specific implementation thereof, and are not described herein again.

It can be seen that, by implementing the method for responding to the user request shown in fig. 4, the problem of high concurrency can be solved to a certain extent by processing different user requests at different time intervals, and the processing efficiency of the user request is improved. In addition, whether the identity of the user is the script or not can be verified through the verification image, so that the user can be prevented from carrying out abnormal electronic certificate obtaining through the script to a certain extent.

Referring to fig. 5, fig. 5 schematically illustrates a flow chart of a method of responding to a user request according to yet another embodiment of the present application. As shown in FIG. 5, a method of responding to a user request of yet another embodiment may comprise: step S510 to step S550, wherein:

step S510: in response to the first user request.

Step S520: the user identity is verified.

Step S530: and outputting the electronic certificate.

Step S540: matching the electronic credential with the user input data.

Step S550: in response to the second user request.

Specifically, the user may first log on the e-commerce platform, and click on an identifier (e.g., a milk powder can pattern) corresponding to a specific event (e.g., purchasing milk powder) for a first preset time period (e.g., a coupon getting time period). Furthermore, the client may receive a first user request corresponding to a user click operation, and after detecting the first user request, may output a verification image, and verify the user identity through the verification image, for example, an image including a verification code, and may further detect whether first user input data for the verification image (i.e., characters input by the user according to the verification code) is consistent with the verification code, so that it may be avoided that the user performs abnormal coupon code pickup through a script. If the electronic credentials (for example, the coupon codes) of the specific event are not received by the user, the coupon codes of the user account corresponding to the first user request can be selected from a plurality of preset electronic credentials (for example, a plurality of preset coupon codes) and output, that is, the above-mentioned output electronic credentials. And if the fact that the user draws the electronic certificate of the specific event is detected (namely, the user account corresponding to the user already has the discount code corresponding to the milk powder purchasing event), displaying the drawn electronic certificate. Further, the user may perform a specific event (e.g., purchase of powdered milk) for a second preset period of time (e.g., a specific event performing stage). Further, the client may receive a second user request corresponding to the user purchase operation. After detecting the second user request, the offer code may be matched to user input data (e.g., characters entered by the user in accordance with the offer code). If the matching is successful, a second user request may be responded, such as for a powdered milk purchase based on the coupon code.

It can be seen that, by implementing the method for responding to the user request shown in fig. 5, the problems of processing efficiency reduction, system crash and the like caused by the fact that the server needs to process a plurality of user requests simultaneously and in parallel can be reduced by executing the pre-purchase discount codes and the purchased commodities in stages, the stability of the system for responding to the user requests is improved, and the use experience of the user is further improved.
