[0072] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0073] Figure 1 The flowchart of an embodiment of a short link generation method provided by an embodiment of the present invention is shown, and the short link generation method is executed by a short link generation device. Figure 1 As shown, the short link generation method includes the following steps:

[0074] Step 110: Obtain the service identifier and long link address of the push information.

[0075] When the push information of the service is triggered, a long link address of the push information will be generated, and the long link address is the original string linking the service.

[0076] Step 120: Obtain summary information of the long link address.

[0077] The summary information is obtained based on the summary algorithm, which is also called a hash algorithm. The summary algorithm is a function that converts data of any length into a data string of fixed length. Common summary algorithms include MD5, SHA-1, SHA-128, SHA-256, SHA-512, and HMAC.

[0078] like Figure 2 As shown, in the embodiment of the present invention, the MD5 algorithm is adopted to calculate the summary information (MD5 summary) of the long link address through the MD5 algorithm to obtain summary information with a length of 128 bits.

[0079] The padding bit length of the MD5 algorithm is: original information length% 512-64 bits (where 64 is the input information length information), and the padding bit length will affect the last 32 bits of the final MD5 algorithm calculation result.

[0080] Step 130: extract a first array from the summary information.

[0081] Specifically, the first array is obtained through a truncation algorithm, and the truncation algorithm is: C=(B>>(32+rolling))&0xFFFFFFFFF, that is, the truncation algorithm truncates the first array of a preset length starting from the M+ith bit of the summary information, where i is an integer and 0≤i≤61; M is the padding bit of the summary algorithm in the summary information. In an embodiment of the invention, M is 32, and the padding bit of the MD5 algorithm is 32 bits.

[0082] For example, Figure 2 As shown, by cutting off the 32-bit padding bits corresponding to the MD5 algorithm, that is, 36 bits starting from the 32+ith bit in the MD5 summary, a first array with better hashing performance can be obtained, wherein i is a rolling value (offset), that is, an offset of the truncation length of the first array, and the value range is [0,61]. In actual application, different roling values ​​are used to obtain different first arrays. The randomness of the first array is improved through random rolling values, so as to reduce the conflict of the first array in different triggering events in different triggering events of the business.

[0083] Step 130: Map the first array into a mapping character array based on a displayable character mapping set.

[0084] In the embodiment of the present invention, the first array is mapped to the mapped character array through a preset displayable character mapping set, wherein the displayable character mapping set is a character matrix.

[0085] Specifically, in order to reduce the amount of calculation of the short link generation device, in some embodiments of the present invention, when the first array is mapped to the mapping character array, the first array is first divided into K second arrays, and then, based on the displayable character mapping set, the K second arrays are mapped to K third arrays, and finally the K third arrays are sequentially spliced ​​to obtain the mapping character array, wherein K is an integer, and K is less than the data bit length of the first array. For example, the 36 bits are evenly divided into 6 second arrays.

[0086] It should be noted that, in the embodiment of the present invention, the data bit length of the first array is L, and L≤SM-i+1; wherein S is the length of the summary information. For example, the data bit length L of the first array is set to 36 bits. Specifically, the number K of the second arrays can be set to 6, and the data bit lengths of the K second arrays are guaranteed to be the same. In this case, the size of the character matrix is ​​2 L / K , where L is the data bit length of the first array, as shown in Table 1, which is a size of 2 provided by an embodiment of the present invention. 6 Character matrix.

[0087] For example, the first array is a 36-bit binary string, which is cut into six 6-bit binary character strings, and six displayable characters are obtained after being mapped by the visible character mapping set.

[0088] For a 6-bit binary string, map the 6 second arrays to the 31-bit displayable character array in turn until all 6 second arrays are mapped. Specifically:

[0089]

[0090] Wherein, λ is the character matrix, a[i] is the truncated bit (6 bits), 0x3F is a fixed value, which is converted to decimal 63, and binary 00111111. It should be noted that the fixed value 0x3F is selected in this application because the number of truncated bits is 6 bits, which makes it easier to implement the "&" operation. In actual applications, other fixed values ​​can also be selected.

[0091] For example, if the intercepted bit is: a[i]=(101001)2, then calculate: a[i]&0x3F=101001B (binary)=41D (decimal), where λ 41 Indicates the 41st displayable character in the character matrix, which corresponds to the size 2 in Table 1. 6 The displayable characters in the character matrix are: E.

[0092] Table 1 is a table of size 2 6 Character Matrix

[0094] Step 150: Concatenate the service identifier and the mapping character array to obtain a short link address of the push information.

[0095] like Figure 2 As shown, when generating the short link address of the push information, it is also necessary to obtain the business identifier corresponding to the push information, and concatenate the business identifier and the mapping character array. It should be noted that the complete short link address also includes the domain name corresponding to the business, that is, the short link address of the push information is: domain name / business identifier / mapping character array, wherein the business identifier is used to indicate the business category of the push information. In this way, when the short link address of the push information is obtained, the business category of the push information can be pre-judged without entering the interface corresponding to the short link address.

[0096] The embodiment of the present invention provides a short link generation method, first, obtaining a service identifier and a long link address of push information, then obtaining summary information of the long link address; and, intercepting a first array from the summary information; and mapping the first array to a mapping character array based on a displayable character mapping set; finally, concatenating the service identifier and the mapping character array to obtain the short link address of the push information. By applying the technical solution provided by the present invention, when the push information of a service is triggered, the service identifier and the original character string corresponding to the long link address of the service can be obtained, and based on the summary algorithm, the interception algorithm and the displayable character mapping set, the mapping character group corresponding to the original character string can be obtained, thereby combining the service identifier to obtain the short link address of the push information of the service, reducing the complexity of the push information, and reducing the probability of misrecognition of the push information.
