Functions

func DumpBody

func DumpBody(r *http.Request, maxSize int64) ([]byte, error)

DumpBody reads the body of a HTTP request without consuming it, so it can be read again later. It will read at most maxSize of bytes. Use -1 to read everything.

It's based on httputil.DumpRequest.

func Fetch

func Fetch(url string) ([]byte, error)

Fetch the contents of an HTTP URL.

This is not intended to cover all possible use cases for fetching files, only the most common ones. Use the net/http package for more advanced usage.

func Save

func Save(url string, dir string, filename string) (string, error)

Save an HTTP URL to the directory dir with the filename. The filename can be generated from the URL if empty.

It will return the full path to the save file. Note that it may create both a file *and* return an error (e.g. in cases of non-200 status codes).

This is not intended to cover all possible use cases for fetching files, only the most common ones. Use the net/http package for more advanced usage.

Types

type ErrNotOK

type ErrNotOK struct {
	URL string
	Err string
}

ErrNotOK is used when the status code is not 200 OK.

func (ErrNotOK) Error

func (e ErrNotOK) Error() string
