Constants ¶

const SniffLen = 512

The algorithm uses at most SniffLen bytes to make its decision.

Variables ¶

var (
	ErrAbortHandler    = errors.New("net/http: abort Handler")
	ErrBodyNotAllowed  = errors.New("http: request method or response status code does not allow body")
	ErrRequestCanceled = errors.New("net/http: request canceled")
	ErrSkipAltProtocol = errors.New("net/http: skip alternate protocol")
)

var ErrLineTooLong = errors.New("header line too long")

Functions ¶

func DetectContentType ¶

func DetectContentType(data []byte) string

DetectContentType implements the algorithm described at https://mimesniff.spec.whatwg.org/ to determine the Content-Type of the given data. It considers at most the first 512 bytes of data. DetectContentType always returns a valid MIME type: if it cannot determine a more specific one, it returns "application/octet-stream".

func NewChunkedReader ¶

func NewChunkedReader(r io.Reader) io.Reader

NewChunkedReader returns a new chunkedReader that translates the data read from r out of HTTP "chunked" format before returning it. The chunkedReader returns io.EOF when the final 0-length chunk is read.

NewChunkedReader is not needed by normal applications. The http package automatically decodes chunking when reading response bodies.

func NewChunkedWriter ¶

func NewChunkedWriter(w io.Writer) io.WriteCloser

NewChunkedWriter returns a new chunkedWriter that translates writes into HTTP "chunked" format before writing them to w. Closing the returned chunkedWriter sends the final 0-length chunk that marks the end of the stream but does not send the final CRLF that appears after trailers; trailers and the last CRLF must be written separately.

NewChunkedWriter is not needed by normal applications. The http package adds chunking automatically if handlers don't set a Content-Length header. Using newChunkedWriter inside a handler would result in double chunking or chunking with a Content-Length length, both of which are wrong.

Types ¶

type FlushAfterChunkWriter ¶

type FlushAfterChunkWriter struct {
	*bufio.Writer
}

FlushAfterChunkWriter signals from the caller of NewChunkedWriter that each chunk should be followed by a flush. It is used by the net/http.Transport code to keep the buffering behavior for headers and trailers, but flush out chunks aggressively in the middle for request bodies which may be generated slowly. See Issue 6574.
