func GetBytes(u *url.URL) ([]byte, error)
GetBytes returns the body of the requested resource, or an error if the response status was not http.StatusOK.
GetBytes is a convenience wrapper around Get and Response.Err.
func Join(u *url.URL, path string) *url.URL
Join returns the result of adding the slash-separated path elements to the end of u's path.
func OpenBrowser(url string) (opened bool)
OpenBrowser attempts to open the requested URL in a web browser.
func Redacted(u *url.URL) string
Redacted returns a redacted string form of the URL, suitable for printing in error messages. The string form replaces any non-empty password in the original URL with "[redacted]".
type HTTPError struct {
URL string // redacted
Status string
StatusCode int
}
An HTTPError describes an HTTP error response (non-200 result).
func (e *HTTPError) Error() string
func (e *HTTPError) Is(target error) bool
type Response struct {
URL string // redacted
Status string
StatusCode int
Header map[string][]string
Body io.ReadCloser
}
func Get(security SecurityMode, u *url.URL) (*Response, error)
Get returns the body of the HTTP or HTTPS resource specified at the given URL.
If the URL does not include an explicit scheme, Get first tries "https". If the server does not respond under that scheme and the security mode is Insecure, Get then tries "http". The URL included in the response indicates which scheme was actually used, and it is a redacted URL suitable for use in error messages.
For the "https" scheme only, credentials are attached using the cmd/go/internal/auth package. If the URL itself includes a username and password, it will not be attempted under the "http" scheme unless the security mode is Insecure.
Get returns a non-nil error only if the request did not receive a response under any applicable scheme. (A non-2xx response does not cause an error.)
func (r *Response) Err() error
Err returns an *HTTPError corresponding to the response r. It returns nil if the response r has StatusCode 200 or 0 (unset).
type SecurityMode int
SecurityMode specifies whether a function should make network calls using insecure transports (eg, plain text HTTP). The zero value is "secure".
const (
SecureOnly SecurityMode = iota // Reject plain HTTP; validate HTTPS.
DefaultSecurity // Allow plain HTTP if explicit; validate HTTPS.
Insecure // Allow plain HTTP if not explicitly HTTPS; skip HTTPS validation.
)
