Archiver (zip)
functionality for archiving files. It includes methods for downloading files from URLs and creating archives from byte data.
Types
IArchiver
type IArchiver interface {
FromURLs(fileName string, urls []string, options *ArchiverOptions) ([]byte, IError)
FromBytes(fileName string, body []ArchiveByteBody, options *ArchiverOptions) ([]byte, IError)
}IArchiver is an interface that defines the archiver's methods.
ArchiverOptions
type ArchiverOptions struct {
}ArchiverOptions represents the options for the archiver.
ArchiveByteBody
type ArchiveByteBody struct {
File []byte
Name string
}ArchiveByteBody represents a byte body for archiving.
Functions
NewArchiver
func NewArchiver(ctx IContext) IArchiverNewArchiver creates a new archiver instance with the provided context.
Methods
FromURLs
func (s archiver) FromURLs(fileName string, urls []string, options *ArchiverOptions) ([]byte, IError)FromURLs downloads files from the provided URLs and creates a zip archive. It returns the archived data as a byte slice and an error.
FromBytes
func (s archiver) FromBytes(fileName string, body []ArchiveByteBody, options *ArchiverOptions) ([]byte, IError)FromBytes creates a zip archive from the provided byte data. It returns the archived data as a byte slice and an error.
createZipFile
func (s archiver) createZipFile(fileName string, fromDir string) ([]byte, IError)createZipFile creates a zip file from the specified directory. It returns the archived data as a byte slice and an error.
downloadFile
func (s archiver) downloadFile(url string, dest string) IErrordownloadFile downloads a file from the specified URL and saves it to the destination path. It returns an error if the download fails.
Error Codes
ARCHIVER_DOWNLOAD_ERROR: Failed to download the file.ARCHIVER_CREATE_FILE_ERROR: Failed to create the file.ARCHIVER_WRITE_FILE_ERROR: Failed to write the downloaded data to a file.ARCHIVER_ZIP_ERROR: Failed to zip the file.ARCHIVER_READ_FILE_ERROR: Failed to read the file.

Example

func main() {
// Create a new archiver
archiver := core.NewArchiver(/* your context */)
// Example 1: Download files from URLs and create a zip archive

}
fileName := "archive"
options := &core.ArchiverOptions{}
archiveData, err := archiver.FromURLs(fileName, urls, options)
if err != nil {

}
fmt.Println("Zip archive created successfully.")
// Example 2: Create a zip archive from byte data

archiveData, err = archiver.FromBytes(fileName, body, options)
if err != nil {

return
}
fmt.Println("Zip archive created successfully.")
// Use the archiveData as needed
fmt.Printf("Archive data: %v\n", archiveData)
