The embodiment of the invention discloses an interface preposition optimization method and device, electronic equipment and a storage medium. The method comprises the following steps: obtaining an interface address and related parameters of a first network request in an HTML page of a target code at a compiling stage of the target code; substituting the interface address and the related parametersinto an interface request preamble template to generate an interface request preamble; inserting the interface request preamble into a position in front of a page script in the HTML page; in the HTMLpage running stage, the interface request preamble and the page script are executed in parallel, and a request result and a request state for executing the interface request preamble are obtained; intercepting a network interface request which is initiated by the HTML page and conforms to the front interface, and returning a request result and a request state to the HTML page. According to the embodiment of the invention, the access automation of the interface preposition is realized, the manpower required for accessing the interface preposition is liberated, and the optimization efficiency of the interface preposition is improved.
