handle

public void handle(String target,
                   Request baseRequest,

            throws IOException

从接口 Handler 复制的描述

Handle a request.

参数：

target - The target of the request - either a URI or a name.

baseRequest - The original unwrapped request object.

request - The request either as the Request object or a wrapper of that request. The AbstractHttpConnection.getCurrentConnection() method can be used access the Request object if required.

response - The response as the Response object or a wrapper of that request. The AbstractHttpConnection.getCurrentConnection() method can be used access the Response object if required.

抛出：

IOException
