[0038] Embodiments of the present application are described in detail below with reference to several drawings. The embodiments described below are illustrative only and are not intended to limit the present application, as the present application can be embodied in various forms.

[0039] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. It will be understood that the terms "vertical", "horizontal", "left", "right", and the like as used herein are used for explanation purposes only and are not intended to limit the scope of the present application.

[0040] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0041] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0043] In the prior art, the setnx method of redis is generally used, but the setnx method cannot set the expiration time, and an expx operation needs to be executed again after the setnx method to release the lock. The two separate commands are atomic operations, and when they are placed together, they are not atomic operations. If the first command is executed, the system is out of order, and the second command is not executed, which may cause a deadlock phenomenon.

[0044] Therefore, the present application aims to overcome the deficiencies in the prior art and provides an information sending method, device, computer equipment and computer readable storage medium.

[0045] Embodiment 1

[0046] As shown in the flowchart of an information sending method in the embodiments of the present application, the information sending method provided by the embodiments of the present application includes the following steps S110-S130: Figure 1 Step S110, generating an information sending identifier according to the receiver's mobile phone number and the short message content.

[0047] Specifically, in the embodiments of the present application, the short message service platform provides a short message sending interface to the background calling, and the background realizes the sending of information by calling the short message sending interface provided by the short message service platform. After receiving the request of sending information through the short message sending interface, the background acquires the short message content (including one or more combinations of text, picture, voice and video) and the receiver's mobile phone number to be sent and saves them into the local database. The information sending identifier is generated by the md5 algorithm, and the receiver's mobile phone number and the short message content are saved as a file in the following manner: receiver's mobile phone number + short message content, such as "12300001234 verification code short message". Then, the saved file is calculated by the md5 algorithm to obtain a 32-bit hexadecimal string (i.e. md5 value), and the md5 value is taken as the information sending identifier. It can be understood that the md5 algorithm is only an example, and other similar encryption algorithms can also be used for implementation, which is not limited here.

[0048] The md5 value of the same file obtained by the md5 algorithm is the same, so the information sending identifier generated by receiving the same short message content and receiver's mobile phone number within a period of time is also the same. Therefore, it can be judged whether the same short message content is repeatedly sent to the same receiver's mobile phone number within a short period of time by judging the information sending identifier (md5 value), and thus the user receiving multiple same short messages is avoided, thereby improving the user experience.

[0049] Step S120, adding a distributed lock to the information sending identifier and storing the locked information sending identifier into the Redis database.

[0050] Further, the information sending identifier is subjected to the distributed lock, and only after the distributed lock is successful, the information sending identifier can be stored into the Redis database. If the distributed lock fails, it indicates that the content in the information sending identifier has been processed by other threads, or the information in the information sending identifier is repeated information.

[0051] Figure 2 ​As shown, the above distributed lock is implemented by the set command of the Redis database, and the generation steps of the set command are as follows:

[0052] In step S121, the number of times that the receiver's mobile phone receives the short message content within the preset time is counted to generate a number of times value.

[0053] In step S122, the overdue time of the receiver's mobile phone receiving the short message content beyond the preset time is counted to generate an overdue value.

[0054] In step S123, the number of times value, the overdue value, and the preset time are integrated to generate the set command set in the Redis database.

[0055] Specifically, the number of times that the receiver's mobile phone receives the short message content within the preset time and the overdue time of the receiver's mobile phone receiving the short message content beyond the preset time are counted, and the two are integrated to generate the set command set in the Redis database. For example, the number of times that the receiver's mobile phone receives the short message content within the preset time is 8 times, the overdue time of the receiver's mobile phone receiving the short message content beyond the preset time is 120 seconds, and the preset time is 60 seconds, and the set command is (8, 120, 60).

[0056] In this embodiment, by distributing the information sending identifier, the problem of repeated sending of the same short message to the user by multiple short message platform threads is solved, the short message sending cost is reduced, the user receives multiple same short message content is avoided, and the user experience is improved.

[0057] In step S130, the set command set in the Redis database is executed on the information sending identifier to obtain a result. If the return result is passed, the short message content is sent to the receiver's mobile phone.

[0058] Specifically, the corresponding set command set in the Redis database is executed on the information sending identifier, and a return result is obtained. If the return result is passed, it means that the set command execution is successful, indicating that the content in the information sending identifier is distributed, and the time of sending the short message content does not exceed the preset time, and the number of times is within the preset number of times threshold. Next, the short message content is sent to the receiver's mobile phone. If the return result is not passed, it means that the set command execution fails, indicating that the content in the information sending identifier is not distributed, or the time of sending the short message content exceeds the preset time, or the number of times exceeds the preset number of times threshold. At this time, an error is reported to the background short message sending interface, and the short message content is not sent to the receiver's mobile phone.

[0059] The set command is simple and easy to understand, and is not prone to deadlock. The preset time and preset number threshold can be set according to actual conditions, effectively solving the problem that an abnormal person repeatedly sends the same short message content to a user in a short time by means of high concurrency, thereby avoiding the user from receiving multiple identical short messages, and improving the user experience.

[0060] In an optional embodiment, the information sending method further includes:

[0061] When the number of times of receiving the short message content exceeds the preset number threshold, triggering a short message alarm to blacklist the sender of the short message content.

[0062] Further, when the number of times of receiving the short message content by the recipient mobile phone within the preset time exceeds the preset number threshold, it indicates that the recipient mobile phone is subjected to short message bombing by an abnormal person. At this time, a short message alarm is triggered to blacklist the sender of the short message content, and the IP address of the sender is listed in the blacklist, which can effectively prevent other recipient mobile phones from being subjected to short message bombing.

[0063] In an optional embodiment, as shown in Figure 3 The information sending method further includes:

[0064] Step S210: storing the preset number threshold in a local database;

[0065] Step S220: determining whether the current date is in an active period. If yes, the preset number threshold is increased; if no, the preset number threshold is decreased.

[0066] It can be understood that the preset number threshold is stored in the local database and dynamically adjusted through a background management website. It is determined whether the current date is in an active period, that is, whether the current date is in a time period of an active promotion. For example, the time period of the bank's "apply for a credit card to give a gift" activity is from May 1, 2022 to June 1, 2022, so the month from May 1, 2022 to June 1, 2022 is in the active period. If it is in the active period, it indicates that the bank needs to focus on promoting the activity, so the number of information to be sent will increase accordingly, and the preset number threshold can be appropriately increased at this time. If the current date is not in the active period, it indicates that the bank has no activity to promote at this time, so the preset number threshold can be appropriately decreased. Through dynamic adjustment of the preset number threshold, real-time and flexible configuration can be performed according to actual conditions, thereby improving the user experience.

[0067] The embodiments of the present application have the following advantages:

[0068] The information sending method provided in the embodiment of the application comprises the following steps: generating an information sending identifier according to a receiver mobile phone number and short message content; adding a distributed lock to the information sending identifier, and storing the information sending identifier after being locked into a Redis database; executing a set command set in the Redis database on the information sending identifier to obtain a return result, and sending the short message content to the receiver mobile phone number if the return result is passed. Through the above method, the problem that an abnormal person repeatedly sends the same short message to a user in a short time by means of high concurrency to bombard a short message sending interface is solved, the user receives multiple same short messages is avoided, and the user experience is improved.
