[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] Currently, various applications and SMS messages have byte limits. Users need long-lived connections when using applications, but these can easily exceed byte limits. Similarly, using long-lived connections increases the cost of SMS messages. Related technologies typically rely on a single server to determine the target short-lived connection based on the target long-lived connection, leading to low processing efficiency.

[0035] To address this issue, embodiments of the present invention provide a method, apparatus, electronic device, and storage medium for generating short links. The method involves acquiring a generation request sent by a user device, wherein the generation request carries a target long link for which a short link is to be generated, and a level parameter. Based on the level parameter, the generation request is routed to a target service node matching the level parameter, thereby mapping the target long link to a target short link with a link length matching the level parameter. If the target service node maps to a target short link, the target short link is obtained from the target service node. Finally, a generation response carrying the target short link is sent to the user device. Therefore, by assigning different target service nodes to different target long links based on the level parameter of the short link to be generated, compared to a single server responding to all generation requests, processing efficiency is improved, while reducing the computational and storage resources required for each service node to generate the target short link.

[0036] The method, apparatus, electronic device, and storage medium for generating short links according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0037] Figure 1 This is a flowchart illustrating a short link generation method provided in an embodiment of the present invention.

[0038] It should be noted that the short link generation method in this embodiment is executed by a short link generation device, which can be implemented by software and / or hardware, and can be configured in a user device. The user device may include, but is not limited to, wearable devices, terminal devices, etc., and this embodiment does not specifically limit the user device.

[0039] like Figure 1 As shown, this short link generation method includes the following steps:

[0040] Step 101: Obtain the generation request sent by the user device, wherein the generation request carries the target long link to be generated as a short link, and the level parameter.

[0041] In an exemplary embodiment, the target long link and level parameter are extracted from the generation request. The target long link is generally a link between a webpage and a target, while the short link is a simplified and readable version of the long link. The target long link can be a webpage address, such as a link starting with "http". The level parameter is the level of the short link to be generated, such as level 1.

[0042] Step 102: Based on the level parameter, the generated request is routed to the target service node that matches the level parameter, so as to map the target long link to the target short link whose link length matches the level parameter.

[0043] In an exemplary embodiment, the network address of the user device is extracted from the generation request; the network address is compared with the anomaly list in the firewall; if the network address is not in the anomaly list, the generation request is routed to the target service node that matches the level parameter according to the level parameter.

[0044] The short link level parameter includes 9 levels, from 1 to 9, each level corresponding to a short link length of 1 to 9, and each level corresponds to a service node. Based on the target service node corresponding to the level parameter, the generated request is routed to the target service node.

[0045] In an exemplary embodiment, an exception message sent by the target service node is received; if, based on the exception message, it is determined that the number of requests sent using network addresses in the received generation requests is greater than a threshold, the network address is added to the exception list.

[0046] In an exemplary embodiment, a rejection response is sent to the user equipment if the network address is in the exception list.

[0047] In an exemplary embodiment, the process of mapping a target long link to a target short link whose link length matches the level parameter, based on the level parameter, can be as follows: After the target service node receives the generation request, it extracts the target long link from the generation request, performs Bloom filtering on the target long link, and uses four hash functions—XXH3, City64, BKDRHash, and APHash—to filter the target long link. Bloom filtering ensures that all target long links in the generation request are in the database of the target service node. After filtering the target long links, a deduplication check is performed on the target long links. The stored mapping relationships are searched to see if a long link identical to the target long link exists. If it exists, the short link corresponding to the target long link with the existing mapping relationship is returned; otherwise, the uncached mapping relationships are searched to see if a long link identical to the target long link exists.

[0048] Step 103: If the target short link is mapped from the target service node, obtain the target short link from the target service node.

[0049] In an exemplary embodiment, the target service node is mapped to obtain a target short link, indicating that a stored mapping relationship exists for the target long link. The target short link is then obtained from the target service node according to the mapping relationship, wherein the target short link is an existing target short link.

[0050] Step 104: Send a generation response carrying the target short link to the user equipment.

[0051] In an exemplary embodiment, the user equipment receives a generation response and extracts the target short link from the generation response.

[0052] In an exemplary embodiment, an exception response is received from the target service node, indicating that all short links corresponding to the level parameters already have corresponding long links; the exception response is then forwarded to the user equipment. Upon receiving the exception response, the user equipment needs to reset the level parameters of the short links to be generated and resend the generation request.

[0053] The short link generation method provided by this invention involves: acquiring a generation request sent by a user device, wherein the generation request carries a target long link to which a short link is to be generated, and a level parameter; routing the generation request to a target service node matching the level parameter, so as to map the target long link to a target short link with a link length matching the level parameter; if the target service node maps to a target short link, retrieving the target short link from the target service node; and sending a generation response carrying the target short link to the user device. Thus, by allocating performance-matched target service nodes to different target long links according to the level parameter of the short link to be generated, compared to a single server responding to all generation requests, processing efficiency is improved, while reducing the computational and storage resources required for each service node to generate the target short link.

[0054] To address potential attacks that may occur when a user device sends a generation request, this embodiment provides an alternative method for generating short links, thereby improving the ability to defend against attacks. Figure 2 This is a flowchart illustrating another short link generation method provided in an embodiment of the present invention.

[0055] like Figure 2 As shown, the short link generation method may include the following steps:

[0056] Step 201: Obtain the list of exceptions for obtaining network addresses.

[0057] In an exemplary embodiment, the process of obtaining a historical list of network addresses may be as follows: receiving exception messages sent by each service node; if, based on the exception messages, it is determined that the number of requests sent using a network address in the received generation requests is greater than a threshold, then the network address is added to the exception list.

[0058] Furthermore, before adding a network address to the anomaly list, the network addresses indicated by the anomaly messages can be grouped and counted. This count indicates the number of anomaly messages associated with that network address, and the count is incremented by one each time an anomaly message is added. A time-related decay factor is applied to the count; after a certain period, the count value decreases to half its original value. If the count value is greater than half its original value after a certain period, it is determined to be consistent with attack behavior, and the network address is added to the historical anomaly list.

[0059] Step 202: Obtain the generation request sent by the user device, wherein the generation request carries the target long link to be generated and the level parameter.

[0060] Step 203: If the network address is on the exception list, send a rejection response to the user equipment.

[0061] In an exemplary embodiment, the network address is compared with an exception list. If the network address is in the exception list, a rejection response is sent to the user equipment, and the processing of the request generated by the user equipment ends. If the network address is not in the exception list, step 205 is executed.

[0062] Step 204: If the network address is not in the exception list, the generated request is routed to the target service node that matches the level parameter, so as to map the target long link to the target short link whose link length matches the level parameter.

[0063] In an exemplary embodiment, after routing the generation request to a target service node that matches the level parameter, the target service node may periodically or non-periodically perform the following steps: extracting the network address of the user device from the generation request; counting the number of requests sent using the network address among the received generation requests; and if it is determined that the number of requests is greater than a threshold, sending an exception message to the control node so that the control node adds the network address to the exception list, thereby updating the exception list.

[0064] Step 205: If the target short link is mapped from the target service node, obtain the target short link from the target service node.

[0065] Step 206: Send a generation response carrying the target short link to the user equipment.

[0066] It should be noted that detailed descriptions of steps 202, 204, 205, and 206 can be found in other embodiments of this invention, and will not be described in detail here.

[0067] In summary, the system improves its attack defense capabilities by obtaining an anomaly list of network addresses; acquiring generation requests sent by user devices, which carry the target long link to be generated, the network address, and a level parameter; sending a rejection response to the user device if the network address is in the anomaly list; routing the generation request to a target service node matching the level parameter, based on the level parameter, to map the target long link to a target short link with a length matching the level parameter; obtaining the target short link from the target service node if it has been mapped; and sending a generation response carrying the target short link to the user device. By comparing the network address in the generation request with a historical anomaly list, and rejecting the generation request if the network address exists in the historical anomaly list, the system enhances its attack defense capabilities.

[0068] To implement the aforementioned short link generation method, this embodiment provides another short link generation method based on the target service node. Figure 3 This is a flowchart illustrating another short link generation method provided in an embodiment of the present invention.

[0069] like Figure 3 As shown, the short link generation method may include the following steps:

[0070] Step 301: Receive the generation request forwarded by the control node, wherein the generation request carries the target long link to be generated and the level parameter, and the target service node matches the level parameter.

[0071] In an exemplary embodiment, the short link generation device receives a generation request forwarded by the control node and extracts the target long link and level parameters from the generation request.

[0072] It should be noted that the target long link in the generated request is a target long link whose link length and level parameter did not match in the mapping relationship in the above embodiment, and the generated request has been routed to the target service node according to the boundary parameter.

[0073] Step 302: Based on the level parameter, map the target long link to the target short link whose link length matches the level parameter.

[0074] In an exemplary embodiment, before mapping a target long link to a target short link whose link length matches the level parameter according to the level parameter, the method further includes: querying whether the target long link has a mapped short link in the cached mapping relationship; if no mapped short link is found, mapping the target long link to a target short link whose link length matches the level parameter according to the level parameter; and storing the mapping relationship between the target long link and the target short link.

[0075] Specifically, if a short link that maps to the target long link is found, the found short link will be used as the target short link.

[0076] In an exemplary embodiment, the network address of the user device is extracted from the generation request; the number of requests sent using the network address is counted among the received generation requests; if the number of requests is determined to be greater than a threshold, an exception message is sent to the control node so that the control node adds the network address to the exception list.

[0077] In an exemplary embodiment, an unused short link index is queried in the short link index library; if an unused short link index is found in the short link index library, the target long link is mapped to a target short link whose link length matches the level parameter according to the level parameter; the unused short link index is used as the index of the target short link, and the unused short link index is updated to be used.

[0078] If all short link indexes in the short link index library are already in use, an exception response is sent to the user equipment through the control node.

[0079] In this embodiment, a distributed key generator is used to generate short link indexes for each service node. Each short link index is unique; for example, the short link index range corresponding to level parameter 1 is 0-63. Therefore, base-64 encoding is used, consisting of characters 0-9, az, AZ, and +-, thereby converting the short link index into the target short link.

[0080] Step 303: Send a generation response carrying the target short link to the user equipment through the control node.

[0081] In an exemplary embodiment, after obtaining the target short link, a generation response is sent to the user device, and the user device extracts the target short link from the generation response. Specifically, if the target long link is a webpage address starting with "http", the generation response is a webpage address starting with "http" combined with the target short link.

[0082] The short link generation method provided by this invention involves receiving a generation request forwarded by a control node. The generation request carries a target long link to which a short link is to be generated and a level parameter, with the target service node matching the level parameter. Based on the level parameter, the target long link is mapped to a target short link with a link length matching the level parameter. The control node then sends a generation response carrying the target short link to the user equipment. Therefore, by mapping the target long link to a target short link with a link length matching the level parameter, the method improves processing efficiency compared to a single server responding to all generation requests, while reducing the computational and storage resources required for each service node to generate the target short link.

[0083] For example, such as Figure 4 As shown, this invention provides another method for generating short links, which includes the following steps:

[0084] Step S1, level routing, which routes the request to generate the short link to the target service node.

[0085] Among them, such as Figure 5 As shown, level routing routes the generated request to the processing cluster (target service node) based on the level parameter attached to the generated request.

[0086] Before step S1, the generation request is processed according to the firewall's blacklist. If the target long link in the request to generate a short link (generation request) is in the blacklist, the generation request is rejected.

[0087] Step S2, link analysis, which involves analyzing the target long links.

[0088] like Figure 6 As shown, the process of the short link generation device executing step S2 can be as follows: Perform a Bloom filter test on the original link (target long link); if the filter fails, directly obtain the target short link sequence number (short link index); if the filter passes, perform precise deduplication on the original link (target long link). In the mapping relationship, query whether there is a long link identical to the original link (target long link). If there is no duplicate, directly obtain the target short link sequence number (short link index); if the original link (target long link) is duplicated, perform attack analysis on the original link (target long link). Count the number of groups based on the address of the generation request, and apply a time-related decay factor to the count, i.e., reduce it to half its original value at regular intervals. Finally, if the count exceeds a threshold, it is determined to be consistent with attack behavior, and the generation request is added to the firewall blacklist; if it is not consistent with attack behavior, return the existing short link sequence number (send a generation response carrying the target short link to the user equipment).

[0089] Step S3, short link number generation, that is, determining the mapping relationship between target long links and target short links, and generating short link indexes.

[0090] like Figure 7 As shown, the process of the short link generation device executing step S3 can be as follows: The distributed number generator generates a unique short link sequence number (short link index) corresponding to the original link (target long link) based on the input level (level parameter) and the original link (target long link). Then, a mapping relationship is constructed based on the input level (level parameter) and the original link (target long link). If the generated short link sequence number (short link index) does not meet the uniqueness requirement, the distributed number generator regenerates the short link sequence number (short link index).

[0091] Step S4: Use an encoder to convert the short link index into the target short link.

[0092] The short link index is converted into the target short link by using base-64 encoding, which consists of characters 0-9, az, AZ, and +-.

[0093] In summary, this method involves routing requests for generating short links to target service nodes; analyzing target long links; determining the mapping relationship between target long links and target short links to generate a short link index; and using an encoder to convert the short link index into target short links. Therefore, based on the level parameters of the short links to be generated, performance-matched target service nodes are assigned to different target long links. Compared to a single server responding to all generation requests, this improves processing efficiency while reducing the computational and storage resources required for each service node to generate target short links.

[0094] To achieve the above embodiments, the present invention also proposes a short link generation device.

[0095] Figure 8 This is a schematic diagram of a short link generation device provided in an embodiment of the present invention.

[0096] like Figure 8 As shown, the short link generation device 800 includes: an acquisition module 810, a routing module 820, a first processing module 830, and a first sending module 840.

[0097] The acquisition module 810 is used to acquire a generation request sent by the user equipment, wherein the generation request carries the target long link to be generated as a short link, and a level parameter.

[0098] The routing module 820 is used to route the generated request to a target service node that matches the level parameter according to the level parameter, so as to map the target long link to a target short link whose link length matches the level parameter according to the level parameter.

[0099] The first processing module 830 is used to obtain the target short link from the target service node when the target short link is mapped to the target service node.

[0100] The first sending module 840 is used to send a generation response carrying the target short link to the user equipment.

[0101] As one possible implementation of this invention, the routing module 820 is specifically configured to extract the network address of the user device from the generation request; compare the network address with an anomaly list in the firewall; and, if the network address is not in the anomaly list, route the generation request to a target service node matching the level parameter according to the level parameter.

[0102] As a possible implementation of this invention, the device 800 further includes: a receiving module and a second processing module; wherein, the receiving module is configured to receive an exception message sent by the target service node; and the second processing module is configured to add the network address to the exception list if, based on the exception message, it is determined that the number of requests sent using the network address in the received generation requests is greater than a threshold.

[0103] As one possible implementation of this invention, the apparatus 800 further includes: a second sending module; wherein the second sending module is configured to send a rejection response to the user equipment when the network address is in the exception list.

[0104] As a possible implementation of this invention, the device 800 further includes: a second receiving module and a forwarding module; wherein the second receiving module is used to receive an abnormal response sent by the target service node, wherein the abnormal response is used to indicate that all short links corresponding to the level parameters have corresponding long links; the forwarding module is used to forward the abnormal response to the user equipment.

[0105] It should be noted that the foregoing explanation of the embodiment of the short link generation method also applies to the short link generation device of this embodiment, and will not be repeated here.

[0106] The short link generation apparatus of this invention obtains a generation request sent by a user equipment, wherein the generation request carries a target long link to which a short link is to be generated, and a level parameter; according to the level parameter, the generation request is routed to a target service node matching the level parameter, so as to map the target long link to a target short link with a link length matching the level parameter; if the target service node maps to a target short link, the target short link is obtained from the target service node; and a generation response carrying the target short link is sent to the user equipment. Thus, by allocating performance-matched target service nodes to different target long links according to the level parameter of the short link to be generated, compared with the method of a single server responding to all generation requests, processing efficiency is improved, while reducing the computing and storage resources required for each service node to generate the target short link.

[0107] like Figure 9As shown, this embodiment of the invention also provides a possible implementation of a short link generation device. The short link generation device 900 includes: a third receiving module 910, a mapping module 920, and a third sending module 930.

[0108] In this embodiment of the invention, the third receiving module 910 is used to receive a generation request forwarded by the control node, wherein the generation request carries a target long link to be generated and a level parameter, and the target service node matches the level parameter.

[0109] The mapping module 920 is used to map the target long link to a target short link whose link length matches the level parameter according to the level parameter.

[0110] The third sending module 930 is used to send a generation response carrying the target short link to the user equipment through the control node.

[0111] As a possible implementation of this invention, the mapping module 920 is further configured to query whether the target long link has a mapped short link in the cached mapping relationship; if no mapped short link is found for the target long link, the target long link is mapped to a target short link with a link length matching the level parameter according to the level parameter; and the mapping relationship between the target long link and the target short link is stored.

[0112] As a possible implementation of this invention, the device 900 further includes: a third processing module; wherein the third processing module is configured to, when a short link mapped to the target long link is found, use the found short link as the target short link.

[0113] As a possible implementation of this invention, the device 900 further includes: an extraction module, a statistics module, and a fourth sending module; wherein, the extraction module is used to extract the network address of the user equipment from the generation request; the statistics module is used to count the number of requests sent using the network address among the received generation requests; and the fourth sending module is used to send an exception message to the control node when it is determined that the number of requests is greater than a threshold, so that the control node adds the network address to the exception list.

[0114] As one possible implementation of this invention, the mapping module 920 is specifically used to query unused short link indexes in the short link index library; if an unused short link index is found in the short link index library, then according to the level parameter, the target long link is mapped to a target short link whose link length matches the level parameter; the unused short link index is used as the index of the target short link, and the unused short link index is updated to be used.

[0115] As a possible implementation of this invention, the device 900 further includes: a fifth sending module; wherein the fifth sending module is used to send an abnormal response to the user equipment through the control node when all short link indexes in the short link index library are occupied.

[0116] It should be noted that the foregoing explanation of the embodiment of the short link generation method also applies to the short link generation device of this embodiment, and will not be repeated here.

[0117] The short link generation apparatus provided by this invention receives a generation request forwarded by a control node. The generation request carries a target long link to which a short link is to be generated and a level parameter, and the target service node matches the level parameter. Based on the level parameter, the target long link is mapped to a target short link with a link length matching the level parameter. The control node then sends a generation response carrying the target short link to the user equipment. Therefore, by mapping the target long link to a target short link with a link length matching the level parameter, the processing efficiency is improved compared to a single server responding to all generation requests, while simultaneously reducing the computational and storage resources required for each service node to generate the target short link.
