Method Detail

parseIpPort

public static IpPort parseIpPort(String address)

The format of address should be IPv4:port or [IPv6]:port, or host:port, or you will not get expected result. Note that the IPv6 address should be wrapped by square brackets.

Returns:

IpPort parsed from input param, or null if the param is null.

parseIpPort

public static IpPort parseIpPort(URI uri)

Parse a URI into an IpPort.

A uri without port is allowed, in which case the port will be inferred from the scheme. http is 80, and https is 443.

The host of the uri should not be null, or it will be treated as an illegal param, and an IllegalArgumentException will be thrown.

parseIpPort

public static IpPort parseIpPort(URI uri,
                                 boolean ignorePortUndefined)

Parse a URI into an IpPort

Parameters:

uri - a uri representing IpPort

ignorePortUndefined - whether the port should be inferred from scheme, when the port part of uri is -1. If true the undefined port is ignored; otherwise a port will be inferred from scheme: http is 80, and https is 443.

parseIpPortFromURI

public static IpPort parseIpPortFromURI(String uriAddress)

Parameters:

uriAddress - the address containing IP and port info.

Returns:

IpPort parsed from input param, or null if the param is null.

parseIpPort

public static IpPort parseIpPort(String scheme,
                                 String authority)

getRealListenAddress

public static String getRealListenAddress(String schema,
                                          String address)

对于配置为0.0.0.0的地址，let it go schema, e.g. http adddress, e.g 0.0.0.0:8080 return 实际监听的地址

getHostName

public static String getHostName()

getHostAddress

public static String getHostAddress()

getIpv6HostAddress

public static String getIpv6HostAddress()

getInterfaceAddress

public static InetAddress getInterfaceAddress(String interfaceName)

ensureGetInterfaceAddress

public static InetAddress ensureGetInterfaceAddress(String interfaceName)

canTcpListen

public static boolean canTcpListen(InetAddress address,
                                   int port)

humanReadableBytes

public static String humanReadableBytes(long bytes)
