PlainSocketFactory

public PlainSocketFactory()

方法详细资料

getSocketFactory

public static PlainSocketFactory getSocketFactory()

Gets the default factory.

返回:

the default factory

createSocket

public java.net.Socket createSocket(HttpParams params)

从接口复制的说明: SchemeSocketFactory

Creates a new, unconnected socket. The socket should subsequently be passed to SchemeSocketFactory.connectSocket(Socket, InetSocketAddress, InetSocketAddress, HttpParams).

指定者:

createSocket 在接口中 SchemeSocketFactory

参数:

params - Optional parameters. Parameters passed to this method will have no effect. This method will create a unconnected instance of Socket class using default constructor.

返回:

a new socket

从以下版本开始:

4.1

createSocket

public java.net.Socket createSocket()

从接口复制的说明: SocketFactory

Creates a new, unconnected socket. The socket should subsequently be passed to connectSocket.

指定者:

createSocket 在接口中 SocketFactory

返回:

a new socket

connectSocket

public java.net.Socket connectSocket(java.net.Socket socket,
                            java.net.InetSocketAddress remoteAddress,
                            java.net.InetSocketAddress localAddress,
                            HttpParams params)
                              throws java.io.IOException,
                                     ConnectTimeoutException

从接口复制的说明: SchemeSocketFactory

Connects a socket to the target host with the given remote address.

Please note that HttpInetSocketAddress class should be used in order to pass the target remote address along with the original HttpHost value used to resolve the address. The use of HttpInetSocketAddress can also ensure that no reverse DNS lookup will be performed if the target remote address was specified as an IP address.

指定者:

connectSocket 在接口中 SchemeSocketFactory

参数:

socket - the socket to connect, as obtained from createSocket. null indicates that a new socket should be created and connected.

remoteAddress - the remote address to connect to.

localAddress - the local address to bind the socket to, or null for any

params - additional parameters for connecting

返回:

the connected socket. The returned object may be different from the sock argument if this factory supports a layered protocol.

抛出:

java.io.IOException - if an I/O error occurs

java.net.UnknownHostException - if the IP address of the target host can not be determined

ConnectTimeoutException - if the socket cannot be connected within the time limit defined in the params

从以下版本开始:

4.1

isSecure

public final boolean isSecure(java.net.Socket sock)
                       throws java.lang.IllegalArgumentException

Checks whether a socket connection is secure. This factory creates plain socket connections which are not considered secure.

指定者:

isSecure 在接口中 SchemeSocketFactory

指定者:

isSecure 在接口中 SocketFactory

参数:

sock - the connected socket

返回:

false

抛出:

java.lang.IllegalArgumentException - if the argument is invalid

@Deprecated
public java.net.Socket connectSocket(java.net.Socket socket,
                                       java.lang.String host,
                                       int port,

                              throws java.io.IOException,
                                     java.net.UnknownHostException,
                                     ConnectTimeoutException

已过时。 (4.1) Use connectSocket(Socket, InetSocketAddress, InetSocketAddress, HttpParams)

从接口复制的说明: SocketFactory

Connects a socket to the given host.

指定者:

connectSocket 在接口中 SocketFactory

参数:

socket - the socket to connect, as obtained from createSocket. null indicates that a new socket should be created and connected.

host - the host to connect to

port - the port to connect to on the host

localAddress - the local address to bind the socket to, or null for any

localPort - the port on the local machine, 0 or a negative number for any

params - additional parameters for connecting

返回:

the connected socket. The returned object may be different from the sock argument if this factory supports a layered protocol.

抛出:

java.io.IOException - if an I/O error occurs

java.net.UnknownHostException - if the IP address of the target host can not be determined

ConnectTimeoutException - if the socket cannot be connected within the time limit defined in the params
