The embodiment of the invention discloses an interface construction method and device, a server and a storage medium. The method comprises the following steps: constructing a base class according to an interface calling method of a dynamic database, wherein the base class is used for calling data through an interface between the base class and the dynamic database; and constructing at least one subclass based on the base class, and constructing an interface according to the at least one subclass. Through the scheme, separation of interface construction and data scheduling is realized; data calling is carried out through the base class; the subclass is constructed based on the base class, the interface is further constructed, the interface can be rapidly constructed, the data unit can be repeatedly utilized, the interface construction efficiency is improved, the method is particularly suitable for a scene of interface construction in the visual inspection software system development process, and the interface construction and software system development time is shortened.
