Functions

func DetectContentType

func DetectContentType(c []byte) (string, map[string]string, error)

DetectContentType returns a best guess representation of the MIME content type for the bytes at c. The value detected by http.DetectContentType is guaranteed not be nil, defaulting to application/octet-stream when a better guess cannot be made. The result of this detection is then run through mime.ParseMediaType() which separates the actual MIME string from any parameters.

func Download

func Download(url string) (resp *http.Response, err error)

Download requests a given URL and returns an io.Reader

func NewHTTPRequestError

func NewHTTPRequestError(msg string, res *http.Response) error

NewHTTPRequestError returns a JSON response error

func ResumableRequestReader

func ResumableRequestReader(c *http.Client, r *http.Request, maxfail uint32, totalsize int64) io.ReadCloser

ResumableRequestReader makes it possible to resume reading a request's body transparently maxfail is the number of times we retry to make requests again (not resumes) totalsize is the total length of the body; auto detect if not provided

func ResumableRequestReaderWithInitialResponse

func ResumableRequestReaderWithInitialResponse(c *http.Client, r *http.Request, maxfail uint32, totalsize int64, initialResponse *http.Response) io.ReadCloser

ResumableRequestReaderWithInitialResponse makes it possible to resume reading the body of an already initiated request.

Types

type ServerHeader

type ServerHeader struct {
	App string // docker
	Ver string // 1.8.0-dev
	OS  string // windows or linux
}

func ParseServerHeader

func ParseServerHeader(hdr string) (*ServerHeader, error)

parseServerHeader extracts pieces from am HTTP server header which is in the format "docker/version (os)" eg docker/1.8.0-dev (windows)
