Functions ¶
func ServeContent ¶
func ServeContent(w http.ResponseWriter, r *http.Request, name string, modtime time.Time, content io.ReadSeeker, size int64)
if name is empty, filename is unknown. (used for mime type, before sniffing) if modtime.IsZero(), modtime is unknown. content must be seeked to the beginning of the file. The sizeFunc is called at most once. Its error, if any, is sent in the HTTP response.
Types ¶
type File ¶
type File interface {
io.Closer
io.Reader
io.Seeker
Readdir(count int) ([]os.FileInfo, error)
Stat() (os.FileInfo, error)
}
A File is returned by a FileSystem's Open method and can be served by the FileServer implementation.
The methods should behave the same as those on an *os.File.
type FileFormReader ¶
type FileFormReader struct {
// contains filtered or unexported fields
}
FileFormReader processes io operation during file upload.
func (*FileFormReader) Read ¶
func (reader *FileFormReader) Read(buff []byte) (int, error)
Read reads bytes from stream, if the buffer has bytes remain, read it first, then read from form body.
func (*FileFormReader) Unread ¶
func (reader *FileFormReader) Unread(read []byte)
Unread return extra read bytes for next read.
type FileSystem ¶
A FileSystem implements access to a collection of named files. The elements in a file path are separated by slash ('/', U+002F) characters, regardless of host operating system convention.
type FileTransactionProcessor ¶
type FileTransactionProcessor struct {
Before func() error
Write func(bs []byte) error
Success func() error
Error func(err error)
}
FileTransactionProcessor is a model for processing one single file of a form.
type FileUploadHandler ¶
type FileUploadHandler struct {
Request *http.Request
// call when read a plain text field.
OnFormField func(paraName, paraValue string)
// call when about begin to read file body from form, need to provide an io.WriteCloser to write file bytes.
OnFileField func(paraName, fileName string) *FileTransactionProcessor
// contains filtered or unexported fields
}
FileUploadHandler defines a handler for processing http file upload.
func (*FileUploadHandler) Parse ¶
func (handler *FileUploadHandler) Parse() error
Parse begin to read request entity and parse form field
