I glued the local json file to the interface of one project according to the official website, and then another project used this interface as the url of swagger doc api 
 but reported an error 
if the Swagger document can only be accessed through the intranet, then the extranet Easy Mock will not be able to create a project for it.
solution
not applicable to OAS 1.2
 copy the JSON data of the document interface, take Petstore as an example 
 create a new interface in Easy Mock, paste the interface data you just copied in the data editor (which may be a bit large) and finish creating 
 copy the URL 
 of the interface you just created. Create a new project, Swagger Docs API text box and fill in the URL 
 you just copied. Click create
