Description

Technical Field

[0002] With the continuous development of the food delivery industry, merchants are receiving more and more food delivery orders. Of course, merchants also have offline orders. Whether it is an online order or an offline order, the order needs to be printed to obtain an order receipt. Merchants set up some printers to print orders. In fact, these printers need to obtain the order data to be printed from the cloud and then print it. After printing, the order printing result information is sent to the cloud.

[0003] When data interacts between the cloud and the printer, such as the cloud sending data to be printed to the printer or the printer sending print completion information to the cloud, a normal connection between the cloud and the printer is required. However, if the connection between the two becomes abnormal, the cloud, unable to send the data to be printed to the printer or receive the print completion information from the printer, will continuously send print requests containing the data to be printed to the printer. Once the connection is restored, the printer will receive a large number of print requests, causing it to be unable to print normally. Even manual repair of the abnormal state is time-consuming and labor-intensive. Therefore, in order printing scenarios, how to efficiently print orders when the connection between the cloud and the printer is abnormal has become a pressing technical problem that needs to be solved.

[0014] Compared with the prior art, this application has the following advantages: The information processing system provided in this application includes: a cloud server, a terminal device installed in a merchant, and a printing device installed in the merchant; the terminal device is used to receive a print instruction containing printable data of a target order sent by the cloud server through a first data channel; the first data channel is a data channel between the terminal device and the cloud server established when the connection between the cloud server and the printing device is in an abnormal state; send the print instruction to the printing device; receive print completion result information for the target order sent by the printing device, and send the print completion result information to the cloud server through the first data channel; the cloud server is used to send the print instruction to the terminal device through the first data channel; receive print completion result information sent by the terminal device; the printing device is used to receive the print instruction sent by the terminal device, determine whether the target order has been printed based on a local idempotent cache used to record completed print orders; if not, print the target order based on the printable data, obtain print completion result information and send it to the terminal device; if yes, directly obtain print completion result information and send it to the terminal device. In this system, when the connection between the cloud server and the printing device is abnormal, the cloud server sends a print command containing the target order's print data to the terminal device via a first data channel. This first data channel is established when the connection between the cloud server and the printing device is abnormal, facilitating the terminal device's subsequent transmission of the print command to the printing device. Upon receiving the print command, the printing device determines whether the target order has already been printed based on its local idempotent cache used to record completed print orders. If not, it prints the target order based on the print data, obtains the print completion result information, and sends it to the terminal device. If yes, it directly obtains the print completion result information and sends it to the terminal device, facilitating the terminal device's subsequent transmission of the print completion result information. The data is sent to the cloud server through the first data channel. When the connection between the cloud server and the printing device is abnormal, the cloud server can send the print command to the terminal device via the first data channel. The terminal device then sends the print command to the printing device. Upon receiving the print command, the printing device, to avoid duplicate printing of the target order, uses a local idempotent cache to determine whether the target order has already been printed. It only prints if the order has not been printed. After obtaining the print completion information, it sends it to the terminal device, which then sends the print completion information to the cloud server via the first data channel. This entire process ensures that order printing can still be performed normally even when the connection between the cloud server and the printing device is abnormal, while also preventing duplicate printing and improving order printing efficiency.

[0029] This application provides an information processing system, an information processing method, an information processing apparatus, an electronic device, and a computer storage medium. The following specific embodiments describe the information processing system, the information processing method, the information processing apparatus, the electronic device, and the computer storage medium.

[0030] First Embodiment This embodiment provides an information processing system; please refer to the following for details. Figure 1 This is a schematic diagram of the information processing system provided in the first embodiment of this application. For specific examples or details regarding this embodiment, please refer to the above scenario embodiment.

[0031] The information processing system of this embodiment includes: a cloud server 101, a terminal device 102 installed in the merchant, and a printing device 103 installed in the merchant.

[0032] Generally, cloud servers communicate directly with printing devices (i.e. printers), specifically through long-distance communication modules; these modules can be mobile network communication modules or wireless network communication modules.

[0033] A cloud server is a server located in the cloud, primarily used to receive online orders generated by merchants, and can also receive offline orders. Users place orders on an online order processing platform, generating orders. The cloud server then obtains the order's print data and sends the print request containing this data to the printing device. The printing device then prints the order based on the print data and sends the print completion information back to the cloud server, thus informing the cloud server that the order has been printed. This is the data processing procedure when the connection between the printing device and the cloud server is normal.

[0034] The cloud server sends a print instruction containing the print data of the target order to the printing device. The printing device prints the target order, obtains the print completion result information for the target order as a print receipt, and sends it to the cloud server.

[0035] However, in some situations, the connection between the cloud server and the printing device may be abnormal. For example, the cloud server may not have sent a print command yet, and the connection between them may be abnormal, preventing the cloud server from sending the print command to the printing device. Alternatively, the connection may be abnormal after the cloud server has sent the print command, preventing the printing device from sending the print completion information to the cloud server. Either way, this will affect the order printing process.

[0036] To address this issue, the printing device incorporates a long-range communication module and a short-range communication module, and / or a wired communication module; the terminal device incorporates a long-range communication module and a short-range communication module, and / or a wired communication module; the printing device communicates with the cloud server via the long-range communication module; the terminal device communicates with the cloud server via the long-range communication module; and the terminal device communicates with the printing device via the short-range communication module, and / or a wired communication module. The short-range communication module can be a Bluetooth module; the wired communication module can be a USB module or an Ethernet module.

[0037] The cloud server and the printing device communicate via a long-distance communication module, establishing a second data channel. This channel is used for data exchange when the connection between the cloud server and the printing device is normal. The cloud server and the terminal device communicate via a long-distance communication module, establishing a first data channel. This channel is used when the connection between the cloud server and the printing device is abnormal. The terminal device then communicates with the printing device via a short-range communication module and / or a wired communication module. In practice, when the connection between the cloud server and the printing device is abnormal, the terminal device acts as an intermediary. The terminal device receives the print command from the cloud server and sends it to the printing device, or it receives the print completion information from the printing device and sends it to the cloud server.

[0038] In fact, through the above methods, the order can be printed normally regardless of whether the connection between the cloud server and the printing device is in a normal or abnormal state.

[0039] The following describes the data interaction methods between cloud server 101, terminal device 102, and printing device 103 when the connection status between the cloud server and the printing device is abnormal and normal, respectively.

[0040] The first data interaction method between cloud server 101, terminal device 102, and printing device 103 is that the connection status between cloud server and printing device is abnormal.

[0041] Terminal device 102 is used to obtain a print instruction containing printable data of a target order sent by a cloud server through a first data channel; the first data channel is a data channel between the terminal device and the cloud server established when the connection status between the cloud server and the printing device is abnormal; send the print instruction to the printing device; obtain print completion result information for the target order sent by the printing device; and send the print completion result information to the cloud server through the first data channel.

[0042] The cloud server 101 is used to send the printing instruction to the terminal device through the first data channel and to obtain the printing completion result information sent by the terminal device.

[0043] The printing device 103 is used to receive the print command sent by the terminal device, and determine whether the target order has been printed based on the local idempotent cache used to record completed print orders; if not, it prints the target order based on the print data, obtains the print completion result information and sends it to the terminal device; if so, it directly obtains the print completion result information and sends it to the terminal device.

[0044] In this embodiment, the terminal device is a device with a print management application or print management applet installed, such as a mobile terminal device, computer terminal device, tablet terminal device, or POS (Point of Sale) terminal device within the merchant's premises. Alternatively, it can be other devices within the merchant's premises with similar functions to the print management application or print management applet, such as scanning devices or printing devices. For example, when multiple printing devices are set up within the merchant's premises, if the connection status between one of the printing devices and the cloud server is abnormal, other printing devices with a normal connection to the cloud server can be used as the terminal device. The terminal device and the printing device are both located within the same merchant's premises to facilitate connection between them via a short-range communication module and / or a wired communication module.

[0045] In this embodiment, the terminal device is further configured to obtain real-time connection status information representing the real-time connection status between the cloud server and the printing device; based on the real-time connection status information, in response to detecting that the connection status between the cloud server and the printing device is abnormal, the terminal device sends a first request message to the cloud server requesting to establish a connection with the cloud server; the cloud server is further configured to establish a first data channel in response to the first request message.

[0046] To facilitate obtaining real-time connection status information, the terminal device also sends a second request message to the cloud server requesting real-time connection status information; it then receives the real-time connection status information from the cloud server in response to the second request message. The cloud server, in turn, responds to the second request message by sending real-time connection status information back to the terminal device. In practice, the terminal device uses its internally installed print management application or print management applet to send the second request message. In fact, all interactions between the terminal device and other terminals (including between the printing device and the cloud server) are conducted using the print management application or print management applet. The terminal device continuously monitors the network connectivity between the printing device and the cloud server, i.e., network status detection.

[0047] The second data interaction method between cloud server 101, terminal device 102, and printing device 103 is that the connection status between the cloud server and the printing device is normal.

[0048] When the connection between the cloud server and the printing device is in a normal state, the cloud server 101 is also used to send the printing instruction to the printing device through the second data channel; and to obtain the printing completion result information sent by the printing device through the second data channel; the second data channel is the data channel between the printing device and the cloud server built when the connection between the cloud server and the printing device is in a normal state.

[0049] Correspondingly, the printing device 103 is used to obtain the print instruction sent by the cloud server, determine whether the target order has been printed based on the local idempotent cache; if not, it prints the target order based on the print data, obtains the print completion result information and sends it to the cloud server through the second data channel; if so, it directly obtains the print completion result information and sends it to the cloud server through the second data channel.

[0050] In fact, in the second data interaction method, the terminal device 102 can detect the connection status between the cloud server and the printing device in real time.

[0051] Regardless of whether the connection between the printing device and the cloud server is normal or abnormal, after receiving the print command, the printing device determines whether the target order has been printed based on the local idempotent cache. If not, it prints the target order based on the print data and obtains the print completion result information. If so, it directly obtains the print completion result information.

[0052] A local idempotent cache is a cache set up on the printing device side. This cache records completed print orders, and the printing device can use order idempotency to determine whether a target order has been printed. Order idempotency means that the same order (uniquely identified) will only be successfully printed once, no matter how many times it is requested to be printed. Therefore, if the local idempotent cache determines that the target order has been printed, the print completion result information for the target order is directly obtained (in fact, the printing device has already obtained the print completion result information before determining that the target order has been printed). If the local idempotent cache determines that the target order has not been printed, the target order is printed based on the data to be printed, and the print completion result information is obtained.

[0053] In fact, the local idempotent cache is used to record the cache of completed printing orders. The local idempotent cache stores the order identifiers that the printing device has completed printing and the printing completion information of the printed orders. Therefore, based on the local idempotent cache, it can be determined whether the target order has been printed. For example, assuming that the printing device has printed order 1, order 2 and order 3, if the target order is order 2, it is determined that it has been printed; if the target order is order 4, it is determined that it has not been printed.

[0054] To further prevent the same order from being printed multiple times, a local idempotent cache is set up on the printing device side, and a cloud idempotent cache is also set up on the cloud server to record orders that have been printed by the printing device; that is, in this application, a double idempotent cache is set up to ensure that the same order will not be printed repeatedly.

[0055] Therefore, before sending the print command (whether to the terminal device or the printing device), the cloud server determines whether the print command meets the preset sending conditions based on the order identifier of the target order and the order identifier of the completed print orders in the cloud idempotent cache. If the print command meets the preset sending conditions, it is sent to the terminal device through the first data channel or to the printing device through the second data channel. If the print command does not meet the preset sending conditions, it is discarded.

[0056] In this embodiment, the cloud server is further configured to store the order identifier of the target order and the sending record information of the sending of the printing instruction in the cloud idempotent cache after sending the printing instruction to the terminal device through the first data channel, or after sending the printing instruction to the printing device through the second data channel.

[0057] For example, on a cloud server, a cursor is maintained for each printing device to identify the last successfully printed order, or a sending channel (i.e., sending record information) is used to send the print instruction to each order record. Both the cursor and the sending channel are cached in an idempotent cache in the cloud. The sending channel can be used to record the print instruction sent to the terminal device through a first data channel, or it can be used to record the print instruction sent to the printing device through a second data channel.

[0058] When the cloud server is about to issue a print command for a target order, it first checks if the order identifier of the target order is greater than the cursor corresponding to the printing device. If the order identifier of the target order is less than or equal to the cursor, it means that the target order is a historical order that has already been processed, i.e., the target order has been successfully printed, and the cloud server has obtained the printing completion information and successfully updated the cursor to the order identifier of the target order in the cloud idempotent cache. The cloud server then discards this print request (which contains the print command). This method can reduce invalid print requests and save network bandwidth and server resources.

[0059] If the order identifier of the target order is larger than the cursor, the print order is allowed to be sent, and the sending channel of this print order action is recorded. For example, it may be marked that the print order instruction for the target order has been sent to the terminal device through the first data channel, or that the print order instruction for the target order has been sent to the printing device through the second data channel. The actual sending channel recorded is determined based on the actual print order situation. When the order identifier of the target order is larger than the cursor, it may be that the cloud server has not yet sent the print order instruction to the terminal device or the printing device; it may also be that the cloud server has sent the print order instruction to the printing device or the terminal device, but the cloud server has not yet received the print completion result information.

[0060] In this embodiment, the cloud server is further configured to, after obtaining the print completion result information, store the order identifier of the target order and the print completion result information correspondingly in a cloud idempotent cache. That is, regardless of whether the cloud server receives print completion result information directly from the printing device or directly from the terminal device, it stores the order identifier of the target order and the print completion result information correspondingly in the cloud idempotent cache. This facilitates updating the target order's successfully printed status in the cloud idempotent cache, such as updating the cursor to the target order's order identifier.

[0061] In this embodiment, regardless of whether the printing device receives a print command from a terminal device or a cloud server, the printing device further stores the target order in a local idempotent cache order queue using the target order's order identifier after printing the target order based on the print data. That is, after completing printing, the printing device stores the printed order identifier in the local idempotent cache.

[0062] Because the number of orders cached in the local idempotent cache is limited, the printing device also checks whether the number of completed print orders stored in the order queue exceeds a preset limit before storing the target order in the local idempotent cache order queue using the target order's order identifier. If the number of completed print orders stored in the order queue exceeds the preset limit, the order that was printed first in the order queue is deleted. For example, if the target order is order 11, and assuming the local idempotent cache order queue can only store ten orders, then after printing the target order, order 1 can be deleted from the order queue.

[0063] To better understand the data or information interaction process between the cloud server 101, terminal device 102, and printing device 103, please refer to... Figure 2 This is a schematic diagram of the interaction process of the information processing system provided in the first embodiment of this application.

[0064] First, the terminal device 102 executes step S201: sending a second request message to the cloud server to obtain real-time connection status information; step S202: obtaining the real-time connection status information sent by the cloud server in response to the second request message; step S203: based on the real-time connection status information, in response to detecting that the connection status between the cloud server and the printing device is abnormal, sending a first request message to the cloud server to establish a connection with the cloud server.

[0065] Cloud server 101 executes step S204: In response to the first request message, establishes a first data channel; step S205: Sends a print instruction containing printable data of the target order to the terminal device through the first data channel.

[0066] Terminal device 102 executes step S206: Sends the print command to the printing device.

[0067] Printing device 103 executes step S207: Based on the local idempotent cache used to record completed printing orders, it determines whether the target order has been printed; if not, it prints the target order based on the data to be printed, obtains the printing completion result information and sends it to the terminal device; if yes, it directly obtains the printing completion result information and sends it to the terminal device.

[0068] Terminal device 102 executes step S208: Send the printing completion result information to the cloud server.

[0069] Terminal device 102 executes step S209: Based on real-time connection status information, in response to detecting that the connection status between the cloud server and the printing device is normal, it sends a third request message to the cloud server to request the printing device to send a printing instruction.

[0070] Cloud server 101 executes step S210: sends the print command to the printing device through the second data channel; Printing device 103 executes step S211: Based on the local idempotent cache, it determines whether the target order has been printed; if not, it prints the target order based on the data to be printed, obtains the printing completion result information, and sends it to the cloud server through the second data channel; if yes, it directly obtains the printing completion result information and sends it to the cloud server through the second data channel.

[0071] It should be noted that the above steps are not strictly in the order of precedence. For example, steps S207 and S211 are not in any particular order; steps S203 and S209 are not in any particular order.

[0072] Of course, this is understandable. Figure 2 The information interaction between the cloud server 101, terminal device 102, and printing device 103 still involves some steps that are not shown. For example, after obtaining the printing completion result information, the cloud server 101 stores the order identifier of the target order and the printing completion result information in the cloud idempotent cache. This information is still within the scope of protection of this application.

[0073] In this system, when the connection between the cloud server and the printing device is abnormal, the cloud server sends a print command containing the target order's print data to the terminal device via a first data channel. This first data channel is established when the connection between the cloud server and the printing device is abnormal, facilitating the terminal device's subsequent transmission of the print command to the printing device. Upon receiving the print command, the printing device determines whether the target order has already been printed based on its local idempotent cache used to record completed print orders. If not, it prints the target order based on the print data, obtains the print completion result information, and sends it to the terminal device. If yes, it directly obtains the print completion result information and sends it to the terminal device, facilitating the terminal device's subsequent transmission of the print completion result information. The data is sent to the cloud server through the first data channel. When the connection between the cloud server and the printing device is abnormal, the cloud server can send the print command to the terminal device via the first data channel. The terminal device then sends the print command to the printing device. Upon receiving the print command, the printing device, to avoid duplicate printing of the target order, uses a local idempotent cache to determine whether the target order has already been printed. It only prints if the order has not been printed. After obtaining the print completion information, it sends it to the terminal device, which then sends the print completion information to the cloud server via the first data channel. This entire process ensures that order printing can still be performed normally even when the connection between the cloud server and the printing device is abnormal, while also preventing duplicate printing and improving order printing efficiency.
