As shown in fig. 1, a memory 1005, which is one type of computer storage medium, may include an operating system, a network communication module, a user interface module, and a short link generation program.
In the short link generation device shown in fig. 1, the network interface 1004 is mainly used for connecting a background server and performing data communication with the background server; the user interface 1003 is mainly used for connecting user equipment; the short link generation device calls the short link generation program stored in the memory 1005 through the processor 1001, and executes the short link generation method provided by the embodiment of the present invention.
Based on the above hardware structure, an embodiment of the short link generation method of the present invention is provided.
Referring to fig. 2, a first embodiment of the short link generation method of the present invention is provided.
In a first embodiment, the short link generation method includes the steps of:
step S10: and encrypting the original long link to be popularized to obtain an encrypted string.
It should be understood that the execution subject of this embodiment is the device that creates an alias for a long Uniform Resource Locator (URL), where the short link generating device may be an electronic device such as a personal computer or a server, and this embodiment is not limited thereto. The generation of the short link can be realized by an MD5 Message Digest Algorithm (MD5 Message-Digest Algorithm, MD5 for short) encryption Algorithm. First we encrypt the original link that we want to promote and the custom key by MD5 to obtain the encrypted string. In this embodiment, the step S10 specifically includes: and encrypting the original long link to be popularized and the custom key by an MD5 encryption algorithm to obtain an encryption string.
Step S20: and grouping the encrypted strings to obtain a preset number of grouped strings.
Step S30: and establishing a corresponding short chain joint initial value for each packet string.
It should be understood that the predetermined number may be determined according to actual conditions, for example, the predetermined number is 4, the encryption strings are divided into 4 groups, and each group corresponds to a short link initial value.
Step S40: and computing each short link initial value, and forming a candidate short link address by each obtained computing result.
It should be noted that, bit and operation are performed on each short link initial value, an obtained result is used as a subscript to select a target character in a preset character table, then, right shift operation is performed on the short link initial value to obtain a new short link value, bit and operation is performed repeatedly with the preset value to obtain a new result, the new result is used as the subscript to select a new target character in the preset character table, and a plurality of characters obtained after repeated execution form a candidate short link address.
Further, in this embodiment, the step S40 specifically includes:
step S1, performing a bit and operation on each of the short link initial values and the first preset value, and performing a bit and operation on the obtained value and the second preset value;
step S2, selecting characters in a preset character table by using the obtained result as a subscript;
and moving the short link initial value by a preset digit to the right to obtain a new short link initial value, repeatedly executing the step S1 and the step S2, and repeatedly executing preset times to obtain a candidate short link address.
In a specific implementation, each preset value may be determined according to an empirical value or an actual condition, for example, the first preset value is 0x3FFFFFFF, the second preset value is 0x0000003D, the preset number of bits is 5 bits, and the preset number of times is 6 times. The initial values and 0x3FFFFFFF are used for carrying out bit AND operation, the obtained values and 0x0000003D are used for carrying out bit AND operation, the obtained results are used as subscripts to select characters in a character table (preset), the initial values are shifted to the right by 5 bits to carry out the same operation, 6 times of repeated operation is carried out to obtain 6 characters, namely a candidate short link address is formed to carry out long-short link mapping relation storage in a short link server, and the mapping relation can be cached in redis at the same time in consideration of the service response performance. In this embodiment, after the step S40, the method further includes: storing the mapping relation between the candidate short link address and the original long link at a short link server; and caching the mapping relation between the candidate short link address and the original long link in the redis. For example, we want to shorten the URL:
http://www.smcaiot.com/#/collection/page/5668639101419520/5649050225344512/5668600916475904/；
a short URL can be obtained by this embodiment: http:// smit.com/jlg 8 zp/.
In the embodiment, the original long link to be promoted is encrypted to obtain an encrypted string, and the security in the link conversion process is improved through encryption operation; the encryption strings are grouped to obtain a preset number of grouping strings, corresponding short link initial values are established for the grouping strings, the short link initial values are calculated, obtained calculation results form candidate short link addresses, an original long link is converted into the candidate short link addresses, the conversion process is simple and high in efficiency, the website is shortened to optimize the link of the cross-device, and the short link is connected to display, print, send messages or release pushtext, so that a large amount of space can be saved, and the error rate of the user input link is reduced.
Referring to fig. 3, a second embodiment of the short link generation method according to the present invention is proposed based on the first embodiment of the method.
In this embodiment, after step S40, the method further includes:
step S50, sending the candidate short link to the target terminal.
It will be appreciated that a significant amount of space can be saved when messaging, information presentation or tweeting is performed over the short candidate links. Further, the user is less likely to miss shorter URLs. The shortened URL is almost one-third the size of the actual URL, shortening the web site for optimizing links across devices.
And step S60, when the user clicks the candidate short link through the target terminal, intercepting and analyzing the http request of the user to obtain the candidate short link.
And step S70, searching the original long link in a preset cache according to the candidate short link.
And step S80, if the page is found, redirecting to the page corresponding to the original long-chain connection.
It should be understood that the preset cache may be a redis cache, and referring to fig. 4, when the user clicks the short links, the short link server may intercept and analyze the http request, first take the short links, search the original links in the redis cache, and if not, search the mapping relationship in the relational database; and if the original long link is found, updating the redis cache, returning a result, and finally redirecting to the original link. In this embodiment, after the step S70, the method further includes: and if the mapping relation between the selected short link and the original long link is not found, searching the mapping relation between the selected short link and the original long link in a relational database.
Referring to fig. 4, in order to ensure access security and accuracy, when the original long link is found, it is further necessary to determine whether the original long link is expired, so as to avoid accessing the expired or invalid link; meanwhile, whether the user has access authority is judged, attack is avoided, and information access safety is improved. In fig. 4, the URL is found, that is, the original long link is found, and when the found URL is out of date or has no access right, no access right is returned; when the found URL is not expired and has access rights, it is redirected to the original long link.
Further, in this embodiment, after the step S60, the method further includes:
acquiring the access times, equipment types, access areas and time period information of the user;
and tracking the behavior of the user according to the access times, the equipment type, the access area and the time period information, and performing data analysis.
It should be noted that, the data analysis can be performed by tracking the behavior of the user through dimensions such as access times, device types, access areas, and time periods. So as to find out which promotion channel is best and analyze the user portrait of the audience. For example: for some c-end apps, short links can be added in voting content, and the click rate of the user is relatively increased due to the simplicity of the short links.
In the embodiment, a large amount of space can be saved when the candidate short link is sent to the target terminal and the short link is displayed, printed, sent or released; when the user clicks the candidate short link through the target terminal, intercepting and analyzing the http request of the user to obtain the candidate short link, searching the original long link in a preset cache according to the candidate short link, and redirecting to a page corresponding to the original long link if the original long link is searched, wherein the short link is simple, and the click rate of the user is improved.
