Functions ¶
func CanonicalHeaderKey ¶
CanonicalHeaderKey returns the canonical format of the MIME header key s. The canonicalization converts the first letter and any letter following a hyphen to upper case; the rest are converted to lowercase. For example, the canonical key for "accept-encoding" is "Accept-Encoding". MIME header keys are assumed to be ASCII only. If s contains a space or invalid header field bytes, it is returned without modifications.
func IsTokenRune ¶
func ParseTime ¶
ParseTime parses a time header (such as the Date: header), trying each of the three formats allowed by HTTP/1.1: TimeFormat, time.RFC850, and time.ANSIC.
func TrimString ¶
TrimString returns s without leading and trailing ASCII space.
func ValidHeaderFieldName ¶
func ValidHeaderFieldValue ¶
Types ¶
type Header ¶
A Header represents the key-value pairs in an HTTP header.
func (Header) Add ¶
Add adds the key, value pair to the header. It appends to any existing values associated with key.
func (Header) Get ¶
Get gets the first value associated with the given key. It is case insensitive; CanonicalHeaderKey is used to canonicalize the provided key. If there are no values associated with the key, Get returns "". To access multiple values of a key, or to use non-canonical keys, access the map directly.
func (Header) Set ¶
Set sets the header entries associated with key to the single element value. It replaces any existing values associated with key.
type HeaderReader ¶
A Reader implements convenience methods for reading requests or responses from a text protocol network connection.
func NewHeaderReader ¶
func NewHeaderReader(r *bufio.Reader) *HeaderReader
NewHeaderReader returns a new Reader reading from r.
To avoid denial of service attacks, the provided bufio.Reader should be reading from an io.LimitReader or similar Reader to bound the size of responses.
func (*HeaderReader) ReadHeader ¶
func (r *HeaderReader) ReadHeader() (Header, error)
ReadHeader reads a MIME-style header from r. The header is a sequence of possibly continued Key: Value lines ending in a blank line. The returned map m maps CanonicalHeaderKey(key) to a sequence of values in the same order encountered in the input.
For example, consider this input:
My-Key: Value 1
Long-Key: Even
Longer Value
My-Key: Value 2
Given that input, ReadHeader returns the map:
map[string][]string{
"My-Key": {"Value 1", "Value 2"},
"Long-Key": {"Even Longer Value"},
}
func (*HeaderReader) ReadLine ¶
func (r *HeaderReader) ReadLine() (string, error)
ReadLine reads a single line from r, eliding the final \n or \r\n from the returned string.
