org.aoju.bus.http.Protocol

All Implemented Interfaces:

Serializable, Comparable<Protocol>

public enum Protocol
extends Enum<Protocol>

协议vs计划 它的名字是:URL.getProtocol() 返回scheme (http, https, etc.)， 而不是协议(http/1.1, spdy/3.1，等等) 请使用这个协议来识别它是如何被分割的 Httpd使用协议这个词来标识HTTP消息是如何构造的

Method Detail

values

public static Protocol[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Protocol c : Protocol.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Protocol valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

get

public static Protocol get(String protocol)
                    throws IOException

Parameters:

protocol - 协议标示

Returns:

返回由protocol标识的协议

Throws:

IOException - if protocol is unknown.

toString

public String toString()

返回用于识别ALPN协议的字符串，如“http/1.1”、“spdy/3.1”或“http/2.0”.

Overrides:

toString in class Enum<Protocol>
