Detailed Description
In order to describe the technical content, constructional features, achieved objects and effects of the technical solution in detail, the following description is made in connection with the specific embodiments in conjunction with the accompanying drawings.
Referring to fig. 1, the present embodiment provides a method for generating a short website. The method for generating the short website can convert the long website into the corresponding short website, and comprises the following steps:
s101, receiving a website conversion request of a short website corresponding to the long website; wherein the long web sites and the short web sites typically employ different snapshots and different ranks, the long web sites being longer in form than the short web sites, and the long web sites typically include "www" and the short web sites typically do not include "www".
S102, carrying out hash calculation on the long website to obtain a corresponding calculated value; the hash calculation is carried out on the long websites, so that calculated values with the same length can be obtained for the long websites with different lengths, the storage is convenient, and the storage capacity can be effectively reduced.
S103, judging whether the calculated value exists in a Redis, wherein the Redis stores a short website and a corresponding calculated value;
if yes, returning to the short website; if not, generating a unique ID of the long website, converting the unique ID into a corresponding short website, and storing the calculated value of the long website and the short website into the Redis.
Wherein, redis is a high-performance key-value database, and the data in Redis are cached in the memory, thereby ensuring the reading and writing efficiency. And the Redis periodically writes updated data to the disk or writes modification operations to the additional record file, and master-slave synchronization is realized on the basis.
In step S103, if the calculated value of the long website is stored in the Redis, the corresponding short website is directly returned from the Redis, so that repeated generation of the short website is not required, and the calculated amount and storage pressure of the system are reduced. If the calculated value of the long website does not exist in the Redis, the calculated value is converted into a corresponding short website according to the unique ID of the long website, and the corresponding short website is stored in the Redis, and as the unique ID of each long website is different, the short website obtained according to the unique ID of the long website is ensured to be different, and therefore collision detection is not needed.
As can be seen from the above description, the short web site generation method can avoid repeated calculation to generate short web sites, reduce the calculation amount and the storage pressure, and generate each short web site differently, so that collision detection is not required.
In an embodiment, the hash calculation of the long website to obtain the corresponding calculated value includes the steps of:
and sequencing the long websites through a preset sequencing algorithm to obtain character strings, and performing message-digest calculation on the character strings to obtain digest values, wherein the digest values are calculated values. Among them, the message-digest calculation is preferably MD5 calculation. Because the website after the sequencing is still very long and the matching performance is poor, the length of the website can be shortened to 32 or 16 bits through MD5 calculation, so that the performance of the website is improved. In other embodiments, other message-digest calculation algorithms such as MD4, MD3, sha-1, RIPEMD, haval, etc. may also be used. MD5 is the message-digest algorithm 5, which allows large volumes of information to be "compressed" into a secure format (i.e., a string of bytes of arbitrary length is converted into a string of hexadecimal digits of certain length) by MD 5.
The long websites are sequenced to obtain a unique character string A, and MD5 calculation is performed on the character string A to obtain an MD5 value B (namely a calculated value). The sorting of the long websites refers to sorting parameters in the long websites, the sorting mode can be sorting of ascending order or descending order of parameter names of the long websites, and the sorting can ensure that a batch of character strings A obtained after parameter sorting are unique. For example:
long web site http:// www.ktvme.comab =122 & kk=32 & bg=333, after ascending order, fixed as: http:// www.ktvme.comab =122 & bg=333 & kk=32.
In one embodiment, the step of generating the unique ID of the long web site and converting the unique ID into the corresponding short web site includes the steps of:
inserting the long website into a mysql database to obtain an auto-increment primary key ID of the long website;
and converting the self-increasing primary key ID into a short website according to a preset binary conversion algorithm.
Wherein, the preset binary conversion algorithm comprises a 62-degree algorithm, a 52-degree algorithm, a 42-degree algorithm and the like.
The mysql database is a relational database and has the advantages of small volume, high speed, low cost, open source code and the like.
In the mysql database, the self-added primary key ID is increased by 1 every time a piece of data is added. Each piece of data has a unique identification (i.e., primary key ID). When the long website is inserted into the mysql database by executing the insertion statement, the self-increasing main key ID of the long website can be obtained, and the self-increasing main key ID can be obtained through the mysql_insert_ID function of the PHP.
In the embodiment, the long website is inserted into the mysql database, and the short website is obtained through the self-increment primary key ID (identity) binary conversion algorithm of the long website, so that the uniqueness of the short website can be ensured, and conflict detection is not needed. In other embodiments, the long website may be inserted into another database such as sqlsvr database or sqlite database to obtain the corresponding self-increasing primary key ID.
Considering that the short website does not support the carrying parameters in the prior art, the use flexibility of the short website is poor. In an embodiment, the method for generating a short website further includes the steps of: the method comprises the steps of presetting a dynamic parameter configuration mode of a short website, wherein the dynamic parameter configuration mode is used for adjusting parameters of a long website corresponding to the short website according to the dynamic parameter configuration mode when the short website is accessed, so that the effect of transparent transmission of dynamic parameters is achieved, namely, the dynamic parameters are transmitted to the corresponding long website when the long website is accessed through the short website.
Wherein the dynamic parameter configuration mode includes: either or both of not supporting dynamic parameter delivery, and supporting partial parameter delivery (i.e., supporting dynamic parameter delivery but preferentially using parameter values in the original long web site).
In practical use, the corresponding dynamic parameter transfer mode (for example, supporting dynamic parameter transfer) can be selected according to the use situation of the short website. When the user accesses the short website, the dynamic parameters of the short website and the parameters of the long website are recombined and arranged and calculated according to the parameter transmission mode judgment preset by the user, so that the effect of transparent transmission of the dynamic parameters is achieved.
The following description will take the example of a user accessing a short web site.
The step of clicking the short website by the user to access the page comprises the following steps:
step one: the user clicks on the short web site.
Step two: the short website service center verifies the correctness of the short website.
Step three: judging a preset dynamic parameter transmission mode of the short website, and combining the dynamic parameters in the short website to rearrange the parameters of the long website according to the dynamic parameter transmission mode.
Step four: the short website service center performs redirection jump to the long website address and carries the rearranged parameters.
Step five: the user sees the desired web page.
In order to more clearly understand the short web site dynamic parameter transparent transmission process, a specific example is described below.
Assume that a long web site a is: http:// www.ktvme.com/a/b/cid=1 & type=4 & abc=222; the long website is converted into a short website under three dynamic parameter transmission modes as follows:
1) Mode 1: https:// s.ktvme.com/asbxjs; mode 1 does not support dynamic parameter delivery;
2) Mode 2: https:// s.ktvme.com/sxsccs; mode 2 supports dynamic parameter delivery, but the parameter values in the original long website are used preferentially;
3) Mode 3: https:// s.ktvme.com/xsssacsa; mode 3 supports dynamic parameters, and the new parameter value can cover the parameter value of the original long website;
the generation of short websites for the above three modes differs only in the option of dynamic parameter mode, and other generation logic is the same.
The three dynamic parameter delivery modes are assumed to be delivered in the same manner by obtaining a short website (i.e. a short link), and carry the same parameters as follows:
4) Mode 1: https:// s.ktvme.com/asbxjstype=10 & kk=2;
5) Mode 2: https:// s.ktvme.com/sxsscstype=10 & kk=2;
6) Mode 3: https:// s.ktvme.com/xsssacctype=10 & kk=2;
when the user accesses 4), since mode 1 is selected and mode 1 does not deliver dynamic parameters, the parameters type=10 & kk=2 on the short web site (i.e. short link) will be discarded and the user accesses directly to the original long web site a.
When the user accesses 5), mode 2 is selected, which allows dynamic parameters to be delivered, but the parameter values in the original long web address are used preferentially. Thus type=10 is discarded, kk=2 is incorporated into the parameter, and the user accesses http:// www.ktvme.com/a/b/cid=1 & type=4 & abc=222 & kk=2.
When the user accesses 6), mode 3 is selected, which allows the delivery of dynamic parameters, the new parameter values will override the parameter values of the original long web address, so that type=10 will override type=4, the user accesses the address http:// www.ktvme.com/a/b/cid=1 & type=10 & abc=222 & kk=2.
Through the dynamic parameter transmission, a shorter short website link can be obtained through the short website service, and the parameters can be transmitted, so that the flexibility and expansibility of short website application are improved.
As shown in fig. 2, in one embodiment of the method for generating a short web address, the method for generating the short web address includes the steps of:
s201, receiving a long website A conversion request and presetting a dynamic parameter configuration mode B; wherein, the dynamic parameter configuration mode B is whether to support the dynamic parameter B, and the dynamic parameter configuration model includes: dynamic parameter transfer is not supported, dynamic parameter transfer is supported, partial parameter transfer is supported (i.e. dynamic parameter transfer is supported but parameter values in the original long website are preferentially used;
s202, converting a long website into a unique character string C by using a sorting algorithm;
s203, performing MD5 calculation on the character string C to obtain a corresponding MD5 value D;
s204, judging whether the MD5 value D exists in Redis; if yes, jump to S208; if not, executing S205;
s205, inserting a long website and a dynamic parameter configuration mode B into a mysql database to obtain an auto-increment primary key ID;
s206, converting the auto-increment primary key ID into a short code E by using a binary algorithm;
s207, storing the MD5 value D and the short code E in a Redis by a Key-value;
s208, returning to the short website.
According to the specific embodiment, the short website generation method uses the self-increment primary key ID of the mysql database to carry out binary conversion to obtain the short code, so that the conversion is quick and collision detection is not needed. And moreover, the MD5 algorithm is adopted after the sorting algorithm, so that repeated requests can be intercepted, and the waste of storage space is reduced. Furthermore, the short website generation method also supports dynamic parameter transparent transmission through a preset dynamic parameter configuration mode, and dynamic parameter application, so that a large number of approximate long websites (such as links with inconsistent parameters) do not need repeated conversion, only need conversion once, and the rest links can be realized only by using dynamic parameters for transmission, thereby greatly improving flexibility and reducing a large number of unnecessary requests.
As shown in fig. 3, in one embodiment, a terminal 300 for generating a short web address is provided. The terminal 300 generating the short web address is used for converting the long web address into a corresponding short web address. The terminal 300 for generating a short web address includes a memory 320, a processor 310 and a computer program stored in the memory 320 and executable on the processor, wherein the processor 310 implements the short web address generation method described in any of the above embodiments when executing the computer program.
As shown in fig. 4, in an embodiment, there is provided a storage medium 400, on which a computer program is stored, the program implementing the short web address generation method described in any of the above embodiments when the computer program is executed by a processor.
It should be noted that, although the foregoing embodiments have been described herein, the scope of the present invention is not limited thereby. Therefore, based on the innovative concepts of the present invention, alterations and modifications to the embodiments described herein, or equivalent structures or equivalent flow transformations made by the present description and drawings, apply the above technical solution, directly or indirectly, to other relevant technical fields, all of which are included in the scope of the invention.
