Embodiment Construction

[0063] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0064] It should be noted that the embodiment of the present invention is applicable to all websites, or all scenarios related to the use of links, such as Weibo, WeChat, and mobile phone text messages.

[0065] Generally, the storage capacity of the system for maintaining short link services is huge, and short links are a trend, and will gradually replace particularly lon...

Abstract

The invention discloses a short link generation method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: receiving a short link generation request; wherein the short link generation request comprises a long link; obtaining a number range and current allocated number information, and obtaining a number allocated to the short link generation request in combination with a predetermined number allocation mode; determining a number plate corresponding to the number, and generating a short link corresponding to the long link in combination with the protocol and the domain name in the long link. According to the embodiment, the to-be-distributed number is stored and maintained through the single machine, wherein single machine sending is achieved through cluster random distribution, then short links are generated through pseudo-random number allocation; therefore, the situation of short link collision is avoided on the whole, and the problem that short link characters are continuous is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a short link generation method and device. Background technique [0002] Short URL service, in simple terms, is to convert a very long URL address (Uniform Resource Locator, uniform resource locator) into a relatively short address and still be used normally, so that users can share links more easily, avoiding line breaks or Exceeding the character limit. [0003] There are two main methods for generating short links: [0004] 1) Message Digest Algorithm MD5 (Message Digest Algorithm MD5, the fifth edition of Message Digest Algorithm): Generate a 32-bit signature string from a long link and divide it into 4 segments, each segment is 1 byte (that is, 8 bits), and then enter it through 16 Obtain the alphabet index through system conversion complement, and then generate a 6-digit short link; [0005] 2) Sequential mapping is used, that is, it is relatively simple to gen...
