Method and device for generating dynamic picture service url

Abstract

The invention discloses a dynamic picture service URL generating method and device. The method comprises the steps that at least a certain number of secret keys are obtained from a preset encryption algorithm and numbered, and a picture service URL generating rule is set; for a picture unloaded by a client side, a secret key corresponding to the serial number is randomly deployed according to the picture service URL generating rule, and picture cutting engine information needing to be carried in the encrypted URL, the information combined with encryption information generated after the serial number and the secret key corresponding to the serial number are used for encrypting the user ID, and the like are set according to the information in the picture; the encrypted URL is stored in the server, and is issued outwards; according to encryption information carried in the encrypted URL and the preset secret key, decryption processing is carried out so as to obtain the plaintext of the user ID, and a picture server dynamically debugs the picture on the basis of the preset picture processing way corresponding to different user IDs. According to the dynamic picture service URL generating method and device, the URL structure can be debugged conveniently, the user privacy will not be exposed, and the pure digital high-performance symmetrical encryption and decryption algorithm is adopted.

Description

technical field [0001] The present application relates to the field of URL processing, in particular, to a method and device for generating dynamic picture service URLs. Background technique [0002] In the prior art, the generation of most image URLs (Uniform Resource Locator, Uniform ResourceLocator, also known as web page address, which is the address (Address) of standard resources on the Internet) on the market is very simple, that is, according to certain rules Directly generate a certain string, such as MD5 (MD5 encryption is Message-Digest Algorithm 5 (information-digest algorithm), which allows large-capacity information to be "compressed" into a confidential format before signing the private key with digital signature software. Developed by RonaldL.Rivest of MIT Laboratory for Computer Science and RSA Data Security Inc in 1991, developed from MD2, MD3 and MD4), and then adding the suffix will solve the problem, at most add some image size information, but generally...

When looking at this URL, I don’t know which user uploaded it, and I don’t know Some other information about this picture, such as size, upload date, etc., the picture server must dynamically generate pictures of various sizes uploaded by users. If the picture path can carry the user ID, it will be very convenient for debugging and testing, but once the user ID is carried , and it will involve user information security and privacy issues; so how to achieve a picture URL structure that is convenient for debugging and does not expose user privacy is very necessary
