type MIMEReader ¶
type MIMEReader struct {
// contains filtered or unexported fields
}
MIMEReader represents a reader that performs MIME type detection and validation on data read from an underlying io.Reader.
func NewMIMEReader ¶
func NewMIMEReader(r io.Reader, allowedContentTypes []string) *MIMEReader
NewMIMEReader creates a new MIMEReader instance with the provided io.Reader and a list of allowed content types.
The MIMEReader is designed to read data from the underlying reader while performing MIME type detection and validation. It allows developers to ensure that the content being read conforms to the expected MIME types. The provided allowedContentTypes is a list of MIME types that are considered valid.
It will stop reading from the underlying reader as soon it detects disallowed content type.
func (*MIMEReader) MIMEType ¶
func (mr *MIMEReader) MIMEType() string
func (*MIMEReader) Read ¶
func (mr *MIMEReader) Read(p []byte) (n int, err error)
Read reads data from the underlying reader into the provided byte slice, performs MIME type detection and validation, and returns the number of bytes read and an error (if any).
- If the MIME type has already been detected, the method reads data until the end of the underlying reader.
- If the MIME type has not been detected, the method continues reading and buffering data until the detection criteria are met.
- Once the detection criteria are met, the buffered data is used to detect the MIME type using http.DetectContentType, and the detected MIME type is compared against the list of allowed content types.
- If the detected MIME type is not in the allowed list, an error is returned.
The method implements the io.Reader interface.
