Functions

func Delete

func Delete(path string)

Delete the file at the given path.

To avoid panics, you should check if the file exists.

func FileExists

func FileExists(file string) bool

FileExists returns true if the file at the given path exists and is readable. Returns false if the given file is a directory.

func GetFileExtension

func GetFileExtension(file string) string

func GetMIMEType

func GetMIMEType(file string) (contentType string, size int64, err error)

GetMIMEType get the mime type and size of the given file. This function calls `http.DetectContentType`. If the detected content type could not be determined or if it's a text file, `GetMIMEType` will attempt to detect the MIME type based on the file extension. The following extensions are supported:

• `.jsonld`: "application/ld+json"
• `.json`: "application/json"
• `.js` / `.mjs`: "text/javascript"
• `.css`: "text/css"

If a specific MIME type cannot be determined, returns "application/octet-stream" as a fallback.

IsDirectory returns true if the file at the given path exists, is a directory and is readable.

type File

type File struct {
	Header   *multipart.FileHeader

}

func ParseMultipartFiles

func ParseMultipartFiles(headers []*multipart.FileHeader) ([]File, error)

ParseMultipartFiles parse a single file field in a request.

func (*File) Save

func (file *File) Save(path string, name string) (filename string, err error)
