FromEnvironment function #
FromEnvironment returns a Config instance populated from the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY (or the lowercase versions thereof). The environment values may be either a complete URL or a "host[:port]", in which case the "http" scheme is assumed. An error is returned if the value is a different form.
func FromEnvironment() *ConfigProxyFunc method #
ProxyFunc returns a function that determines the proxy URL to use for a given request URL. Changing the contents of cfg will not affect proxy functions created earlier. A nil URL and nil error are returned if no proxy is defined in the environment, or a proxy should not be used for the given request, as defined by NO_PROXY. As a special case, if req.URL.Host is "localhost" or a loopback address (with or without a port number), then a nil URL and nil error will be returned.
func (cfg *Config) ProxyFunc() (func(reqURL *url.URL) (*url.URL, error))canonicalAddr function #
canonicalAddr returns url.Host but always with a ":port" suffix
func canonicalAddr(url *url.URL) stringgetEnvAny function #
func getEnvAny(names ...string) stringhasPort function #
Given a string of the form "host", "host:port", or "[ipv6::address]:port", return true if the string includes a port.
func hasPort(s string) boolidnaASCII function #
func idnaASCII(v string) (string, error)init method #
func (c *config) init()isASCII function #
func isASCII(s string) boolmatch method #
func (a allMatch) match(host string, port string, ip net.IP) boolmatch method #
func (m cidrMatch) match(host string, port string, ip net.IP) boolmatch method #
func (m ipMatch) match(host string, port string, ip net.IP) boolmatch method #

func parseProxy(proxy string) (*url.URL, error)proxyForURL method #
func (cfg *config) proxyForURL(reqURL *url.URL) (*url.URL, error)useProxy method #
useProxy reports whether requests to addr should use a proxy, according to the NO_PROXY or no_proxy environment variable. addr is always a canonicalAddr with a host and port.
