write me a javascript function that parses swagger JSON file and returns all POST endpoints as array of objects with url property and parse the object shape from the #/definitions part and add that as a property named 'obj'

function getPostEndpoints(swagger){
  return swagger.paths
    .filter(p => p.post)
    .map(p => {
      return {
        url: p.path,
        obj: swagger.definitions[p.post.parameters[0].schema.$ref.replace('#/definitions/', '')]
      }
    })
}
