示例1: getVulnerabilitiesFromLayerPackagesNodes

// getVulnerabilitiesFromLayerPackagesNodes returns the list of vulnerabilities
// affecting the provided package nodes, filtered by Priority.
func getVulnerabilitiesFromLayerPackagesNodes(packagesNodes []string, minimumPriority types.Priority, selectedFields []string) ([]*database.Vulnerability, error) {
	if len(packagesNodes) == 0 {
		return []*database.Vulnerability{}, nil
	}

	// Get successors of the packages.
	packagesNextVersions, err := getSuccessorsFromPackagesNodes(packagesNodes)
	if err != nil {
		return []*database.Vulnerability{}, err
	}
	if len(packagesNextVersions) == 0 {
		return []*database.Vulnerability{}, nil
	}

	// Find vulnerabilities fixed in these successors.
	vulnerabilities, err := database.FindAllVulnerabilitiesByFixedIn(packagesNextVersions, selectedFields)
	if err != nil {
		return []*database.Vulnerability{}, err
	}

	// Filter vulnerabilities depending on their priority and remove duplicates.
	filteredVulnerabilities := []*database.Vulnerability{}
	seen := map[string]struct{}{}
	for _, v := range vulnerabilities {
