方法详细资料

init

public void init(Protocol<NativePacketPayload> prot)

从接口复制的说明: AuthenticationPlugin

We need direct Protocol reference because it isn't available from Connection before authentication complete.

指定者:

init 在接口中 AuthenticationPlugin<NativePacketPayload>

覆盖:

init 在类中 Sha256PasswordPlugin

参数:

prot - protocol instance

reset

public void reset()

从接口复制的说明: AuthenticationPlugin

Resets the authentication steps sequence.

destroy

public void destroy()

从接口复制的说明: AuthenticationPlugin

Called by the driver when this extension should release any resources it is holding and cleanup internally before the connection is closed.

指定者:

destroy 在接口中 AuthenticationPlugin<NativePacketPayload>

覆盖:

destroy 在类中 Sha256PasswordPlugin

getProtocolPluginName

public String getProtocolPluginName()

从接口复制的说明: AuthenticationPlugin

Returns the name that the MySQL server uses on the wire for this plugin

指定者:

getProtocolPluginName 在接口中 AuthenticationPlugin<NativePacketPayload>

覆盖:

getProtocolPluginName 在类中 Sha256PasswordPlugin

返回:

plugin name

nextAuthenticationStep

public boolean nextAuthenticationStep(NativePacketPayload fromServer,
                                      List<NativePacketPayload> toServer)

从接口复制的说明: AuthenticationPlugin

Process authentication handshake data from server and optionally produce data to be sent back to the server. The driver will keep calling this method until either an Exception is thrown (authentication failure, please use appropriate SQLStates) or the method returns false or driver receives an OK packet from the server which indicates that the connection has been already approved. If, on return from this method, toServer is a non-empty list of buffers, then these buffers should be sent to the server in order and without any reads in between them. If toServer is an empty list, no data should be sent to server. If method returns true, it means that this plugin does not need any more data from the server to conclude the handshake and this method should not be called again. (Note that server can send an Auth Method Switch request and then another handshake will start, possibly using a different plugin.) If this method returns false, it means that plugin needs more data from the server to conclude the handshake. In that case next handshake data payload should be read from the server (after possibly writing data from toServer as explained above). Then this method should be called again with the new data in fromServer parameter. In case of errors the method should throw Exception.

指定者:

nextAuthenticationStep 在接口中 AuthenticationPlugin<NativePacketPayload>

覆盖:

nextAuthenticationStep 在类中 Sha256PasswordPlugin

参数:

fromServer - a buffer containing handshake data payload from server (can be empty).

toServer - list of buffers with data to be sent to the server (the list can be empty, but buffers in the list should contain data).

返回:

False if more data should be read from the server and next call to this method made, true otherwise.

encryptPassword

protected byte[] encryptPassword()
