Information processing method, device and system, electronic equipment and storage medium

The invention provides an information processing method, device and system, electronic equipment and a storage medium, and the method comprises the steps: converting a to-be-converted first link intoa unique character string after receiving a link conversion request, and splicing a preset domain name with the character string to obtain a second link. As the sum of the length of the character string and the character length of the domain name is less than a first threshold value, it can be guaranteed that the character length of the second link is less than the character length of the first link. The first link is a link included in the to-be-sent information, so that by returning the second link to replace the first link in the to-be-sent information with the second link, the character length of the to-be-sent information can be effectively shortened. Besides, the character string obtained after the first link is converted has uniqueness, and the second link is obtained by splicing the preset domain name and
