Description of the Drawings

[0073] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0074] Figure 1 is a flowchart of a method for verifying the reasonableness of a price provided by an embodiment of the present invention;

[0075] Figure 2 is a timing diagram provided by an embodiment of the present application;

[0076] Figure 3 is a structural block diagram of a device for verifying the reasonableness of a price provided by an embodiment of the present application. Detailed Embodiments

[0077] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to the drawings.

[0078] Figure 1 is a flowchart of a method for verifying the reasonableness of a price provided by an embodiment of the present invention. Referring to Figure 1 , the method for verifying the reasonableness of a price provided by an embodiment of the present invention may include:

[0079] Step 110, the server receives the target information sent by the client, where the target information includes the first price for the target commodity, and the first price is the price of the target commodity at the first time point when the user makes a bid through the client.

[0080] Among them, the server may be a server. The client may be an electronic device, such as a mobile phone, a computer, etc., or may also be various applications installed on the electronic device, such as an application program on the electronic device or a small program relying on the application program installed on the electronic device.

[0081] Step 120, the server calculates the second price of the target commodity according to the second time point when the target information of the target commodity is received.

[0082] Step 130: The server verifies whether the first price of the target commodity is reasonable based on the first price and the second price.

[0083] Wherein, the price of the target commodity changes over time, and the client and the server adopt the same commodity price calculation rule. The commodity calculation rule can be a formula or a function. For example, a formula or a function for price decay over time.

[0084] In the embodiment of the present application, the server obtains the first price of the target commodity at the first time point and the second price at the second time point, and verifies the first price from the client based on these two prices. In this way, it can be ensured that only the first price that passes the verification will be traded, preventing the client from sending unreasonable prices, thus solving the problem that the client sending unreasonable prices affects fairness.

[0085] Optionally, in an embodiment of the present application, the price of the target commodity decreases over time within a preset time period. Correspondingly, in step 130, the server verifying whether the first price of the target commodity is reasonable based on the first price and the second price includes:

[0086] The server compares the first price and the second price;

[0087] In the case where the first price is greater than the second price, the server determines that the first price of the target commodity is reasonable;

[0088] In the case where the first price is not greater than the second price, the server determines that the first price of the target commodity is unreasonable.

[0089] In this way, it is possible to directly determine whether the first price from the client is reasonable by comparing the prices.

[0090] In the embodiment of the present application, if the time point when the customer makes an offer through the client is t1, the client sends the offer information to the server through the network, and the time point when the server receives the offer information is t2. In the case of clock synchronization between the client and the server, t2 is greater than t1.

[0091] In the embodiment of the present application, the price of the commodity can decay over time, and the rule can be y = f(t), where y is the price and t is the time. Then, correspondingly, the price at time point t1 is y1, and the price at time point t2 is y2. In the case where the price of the commodity decays over time, y2 is less than y1. Therefore, when the server verifies, if the received offer is less than the price at the current time point calculated according to the price decay formula, it must be an unreasonable offer.

[0092] Optionally, in an embodiment of the present application, before the server receives the target information sent by the client, synchronize the time of the client and the server so that the time of the client and the server remains synchronized. In this way, the first price and the second price can be directly compared to determine whether the first price for the target commodity is reasonable.

[0093] In the case where the time of the client and the server is not synchronized, the time deviation between the two can also be determined first, and then the time of the client and the server can be adjusted to be synchronized based on the time deviation. Therefore, in an embodiment of the present application, the method for verifying the reasonableness of the price provided by the embodiment of the present application may further include:

[0094] In the case where the time of the client and the server is not synchronized, determine the time deviation between the server and the client;

[0095] Based on the time deviation, adjust the time of the client so that the time of the client and the server remains synchronized.

[0096] In this way, the method for verifying the reasonableness of the price provided by the embodiment of the present application can be applied not only to the case where the server and the client maintain time synchronization, but also to the case where the time of the server and the client is not synchronized. By determining the time deviation and then adjusting, it can ensure the time synchronization of the server and the client.

[0097] Optionally, in an embodiment of the present application, the process of determining the time deviation between the server and the client may include:

[0098] Obtain a first timestamp, where the first timestamp is the timestamp when the client sends the target data packet;

[0099] Obtain a second timestamp, where the second timestamp is the timestamp when the server receives the target data packet;

[0100] Obtain a third timestamp, where the third timestamp is the timestamp when the server sends the response data packet of the target data packet;

[0101] Obtain a fourth timestamp, where the fourth timestamp is the timestamp when the client receives the response data packet;

[0102] Based on the first timestamp, the second timestamp, the third timestamp, and the fourth timestamp, determine the time deviation between the server and the client.

[0103] In this way, the time deviation between the server and the client can be accurately calculated through the above four timestamps, and then time synchronization can be performed.

[0104] In the embodiments of the present application, the target data packet may be a Network Time Protocol (NTP) data packet. The typical time synchronization method of NTP is the Client / Server method. As Figure 2 shown, the client first sends an NTP data packet to the server, which contains the timestamp T1 when the packet leaves the client. When the server receives the packet, it can fill in the timestamp T2 when the packet arrives, the timestamp T3 when the response packet leaves, and then immediately return the response packet to the client. When the client receives the response packet, it can record the timestamp T4 when the response packet returns. The client can use these four time parameters to calculate two key parameters: the round-trip delay d of the NTP packet and the time deviation t between the client and the server. The client can use this time deviation to adjust the local clock to ensure that the time of the client is consistent with the time of the server.

[0105] In Figure 2 , T1 is the timestamp when the client sends the NTP data packet (referenced by the time of the client); T2 is the timestamp when the server receives the NTP data packet (referenced by the time of the server); T3 is the timestamp when the server sends the NTP response packet (referenced by the time of the server); T4 is the timestamp when the client receives the NTP response packet; d1 is the transmission delay of the NTP data packet; d2 is the transmission delay of the NTP response packet; t is the time deviation between the client and the server; d is the round-trip time of the NTP data packet.

[0106] When T1, T2, T3, and T4 are all known, the following formulas can be listed:

[0107] T2 = T1 + t + d1

[0108] T4 = T3 - t + d2

[0109] d = d1 + d2

[0110] Through the above three formulas, assuming that the transmission delays of the NPT request and response packets are equal, that is, d1 = d2, then it can be solved that:

[0111] t = [(T2 - T1) - (T4 - T3)] / 2

[0112] d = (T2 - T1) + (T4 - T3)

[0113] It can be seen from the above that t and d are only related to the difference between T2 and T1 and the difference between T4 and T3, and have nothing to do with the difference between T2 and T3. That is, the final result has nothing to do with the time for the server to process the data packet. Therefore, the client can adjust the local time through T1, T2, T3, and T4.

[0114] Currently, more and more clients are presented in the form of applications (APPs) or mini-programs. Clients in the form of APPs or mini-programs are restricted by the mobile operating system or the mini-program host application and cannot easily and simply correct the host time. In the embodiments of the present application, when the client is an application or a mini-program on the host, the time synchronization method between the application or mini-program on the host and the server can be as follows:

[0115] When the application or mini-program on the electronic device sends a request to the server, add the T1 timestamp of the host in the request parameters;

[0116] After the server processes the request, in the return result, in addition to returning the T1 timestamp as it is, the T2 and T3 timestamps of the server can also be added;

[0117] After the application or mini-program on the host receives the response from the server, add the T4 timestamp of the host, so that the time correction value of the application or mini-program on the host can be calculated using the above formula.

[0118] Optionally, in the embodiments of the present application, the target data packet sent by the client to the server can also be a data packet requesting product display data. In this case, the process of adopting the above time synchronization method can be:

[0119] When the client sends a data packet requesting product display data to the server, add the T1 timestamp of the client in the request parameters of the data packet;

[0120] After the server receives this data packet, in the return result, in addition to returning the T1 timestamp of the client as it is, the T2 and T3 timestamps of the server are also added;

[0121] After the client receives the response from the server, add the T4 timestamp of the client, thereby calculating the time deviation between the server and the client, and then performing time synchronization.

[0122] In the embodiments of the present application, after the client sends a data packet requesting product display data to the server, the client can display the target product according to the feedback from the server. In the embodiments of the present application, before step 110, a target page can be displayed on the electronic device, and the target page includes the target product and the target price of the target product, where the target price of the target product can change with time.

[0123] Among them, the electronic device can be a terminal device such as a mobile phone or a computer. The target page can be the page where the target commodity is currently sold. The target commodity can be a specific commodity, for example, a certain kind of rice, a certain kind of cooking oil, etc. The target price can be the price at which the target commodity is currently sold. For example, 10 catties of a certain kind of rice are currently sold at 30 yuan.

[0124] In the embodiment of the present application, the time can be the time displayed on the target page in a specified form, such as a countdown form, which is conducive to the user observing the change of time. Of course, the time may not be directly displayed, but advanced on the target page in the form of a progress bar, for example.

[0125] The term "time" in the embodiment of the present application can represent the time displayed on the target page. For example, the time displayed in the form of a countdown, 15 seconds, 14 seconds, 13 seconds..., or it can also represent the time not displayed on the target page. At the same time, the time can also refer to the time for the displayed target commodity. The target commodity can be set with time, for example, the time is 1 hour, 30 minutes, 1 minute, etc.

[0126] Among them, the fact that the target price of the target commodity changes with time can mean that the target price of the target commodity decreases as time passes. Taking 1 minute as an example, the initial selling price of 10 catties of a certain kind of rice is 30 yuan. When the time is 1 minute, it can be 30 yuan at the first second, 29.9 yuan at the second second, 29.8 yuan at the third second, and so on. That is, the price of the target commodity can be adjusted once every unit time, for example, once every second.

[0127] After the target page is displayed on the electronic device, the target input of the user can be received; and according to the target input, the selected price corresponding to the target commodity can be determined, where the selected price changes with the input time of the target input. Furthermore, the client can send target information to the server, and the target information includes the target commodity and the selected price

[0128] Among them, the user can be the purchaser of the commodity. The target input can be any common operation for triggering the purchase of the target commodity, such as a click input on a specified position on the target page, or a swipe input on the target commodity, etc.

[0129] When the user sees that the current price of the target commodity meets their psychological expectations, they can perform a target input on the target page on the electronic device.

[0130] In the embodiment of the present application, after receiving the target input of the user, the selected price for the user can be determined. For example, when the user clicks on a specified position on the target page, the selected price can be determined according to the time of the user's click input, such as the difference between the time point when the commodity sale starts and the time point when the click input is received. During the whole process, since the price of the target commodity can gradually decrease, different selected prices can be obtained according to the target input of the user at different time points. Taking 2 minutes as an example, the initial selling price of 10 catties of a certain kind of rice is 30 yuan. At the 1st minute, it can be 30 yuan at the 1st second, 29.9 yuan at the 2nd second, 29.8 yuan at the 3rd second, and so on. If the user makes a target input at the 3rd second, the selected price can be determined as 29.8 yuan. If the user makes a target input at the 5th second, the selected price can be determined as 29.6 yuan, and so on for subsequent time points.

[0131] In the embodiment of the present application, rules for determining the selected price can be built into the electronic device. In this way, after receiving the target input, the selected price corresponding to the target commodity can be determined according to these rules. Of course, rules for determining the selected price can also be built into the server. The electronic device can determine the selected price corresponding to the target commodity by interacting with the server.

[0132] After obtaining the selected price, the target commodity and the selected price can be sent to the server. After receiving the information such as the target commodity and the selected price submitted by the electronic device, the server can verify according to relevant rules, check the rationality and correctness of the relevant information, and can feedback the verification result to the electronic device. In this way, the electronic device can perform subsequent operations according to the feedback result.

[0133] It should be understood that in the embodiment of the present application, in the case of multiple users, the commodity can be sold to the user who makes the target input first. Taking 2 minutes as an example, the initial selling price of 10 catties of a certain kind of rice is 30 yuan. At the 1st minute, it can be 30 yuan at the 1st second, 29.9 yuan at the 2nd second, 29.8 yuan at the 3rd second, and so on. For example, if Zhang San makes a target input at the 3rd second, Zhang San's selected price is 29.8. If Li Si makes a target input at the 5th second, Zhang San's selected price is 29.6. However, since Zhang San has made a target input earlier than Li Si, the commodity will be sold to Zhang San first.

[0134] In an embodiment of the present application, a target page is displayed on an electronic device. The target page includes a target commodity and a target price of the target commodity. Wherein, the target price of the target commodity changes over time; a target input of a user is received; according to the target input, a selected price corresponding to the target commodity is determined, wherein the selected price changes with the input time of the target input; target information is sent to a server, and the target information includes the target commodity and the selected price. In this way, based on the target input of the user, the selected price corresponding to the target commodity can be determined, and the determined selected price changes with the input time of the target input, allowing the user to participate in the sales process of the target commodity, greatly stimulating the user's purchase enthusiasm, thereby improving the sales efficiency of the commodity, and thus solving the problem of low sales efficiency of the commodity.

[0135] Optionally, in an embodiment of the present application, the target price of the target commodity decreases over time within a preset time period, and the selected price decreases as the input time of the target input is delayed within the preset time period. The preset time can be set as needed. For example, the preset time is 2 minutes. The initial selling price of a certain 10 - jin bag of rice is 30 yuan, and the time is 1 minute. Then it can be 30 yuan at the first second, 29.9 yuan at the second second, 29.8 yuan at the third second, and so on. Within these 2 minutes, the later the input time of the target input, the lower the selected price. However, if the input time is too late, there may be a situation where the target commodity cannot be purchased. In this way, it can stimulate the purchase desire of the buyer and further improve the sales efficiency.

[0136] In an embodiment of the present application, optionally, a price range can also be set for the target commodity. Further, within the price range, the target price of the target commodity decreases over time within a preset time period; within the price range, the selected price decreases as the input time of the target input is delayed within the preset time period.

[0137] Optionally, in an embodiment of the present application, the preset time period includes a first time period and a second time period. The target price of the target commodity decreases uniformly with the passage of time within the first time period, and the target price of the target commodity decreases variably with the passage of time within the second time period. The preset time is, for example, 2 minutes. The first time period can be 1 minute and 30 seconds, and the second time period can be 30 seconds. The initial selling price of a certain 10-jin bag of rice is 30 yuan. Within the first 1 minute and 30 seconds, the first unit amount, for example, 0.1 yuan, can be reduced every first unit of time, for example, one second. Specifically, it can be 30 yuan at the first second, 29.9 yuan at the second second, 29.8 yuan at the third second, and so on, until it is 21 yuan at the 1 minute and 30 second. In the last 30 seconds, the second unit amount, for example, 0.2 yuan, can be reduced every second unit of time, for example, one second. Specifically, it can be 20.8 yuan at the 1 minute and 31 second, 20.6 yuan at the 1 minute and 32 second, and so on. In this way, the time settings of different time periods can be fully utilized to further stimulate the purchasing desire of the purchaser and further improve the sales efficiency.

[0138] Optionally, in an embodiment of the present application, the target price of the target commodity and time satisfy a preset function. The preset function can be a linear function or an exponential function. Among them, the linear function can decrease linearly with time within the first price range, and the exponential function can decrease exponentially with time within the second price range. Among them, the first price range and the second price range can be set according to requirements.

[0139] The preset function includes y = a - bx, where y is the target price, a and b are constants, and x is time. Among them, time can be time advancing in sequence according to the unit time. For example, the unit time is one second, and time can be the 1st second, the 2nd second, the 3rd second, and so on. In the embodiment of the present application, time can be within the preset time period. For example, if the preset time period is 30 seconds, the value range of time is from 1 to 30. In this way, it can ensure that the price fluctuates with the linear function. The price can be reduced as soon as possible within a short time, thereby improving the sales efficiency.

[0140] Or, the preset function includes y = a - bx 2 , where y is the target price, a and b are constants, and x is time. Among them, time can be time advancing in sequence according to the unit time. For example, the unit time is one second, and time can be the 1st second, the 2nd second, the 3rd second, and so on. In the embodiment of the present application, time can be within the preset time period. For example, if the preset time period is 15 seconds, the value range of time is from 1 to 15.

[0141] Optionally, in an embodiment of the present application, the method for verifying the reasonableness of a price provided by the embodiment of the present application may further include:

[0142] Receiving a verification result for the target information;

[0143] In the case where the verification result indicates that the target information passes the verification, trading the target commodity based on the selected price.

[0144] In this way, it can be ensured that only the verified target information will be adopted, improving the authenticity and accuracy of the transaction. Moreover, the effectiveness of the transaction can be ensured, avoiding a large number of invalid target information from triggering transactions and improving the transaction efficiency.
