com.ptteng.course.util.aliPayUtil.apacheCommonUtil.httpclient.methods.HeadMethod

所有已实现的接口:

HttpMethod

public class HeadMethod
extends HttpMethodBase

Implements the HTTP HEAD method.

The HTTP HEAD method is defined in section 9.4 of RFC2616:

The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response. The metainformation contained in the HTTP headers in response to a HEAD request SHOULD be identical to the information sent in response to a GET request. This method can be used for obtaining metainformation about the entity implied by the request without transferring the entity-body itself. This method is often used for testing hypertext links for validity, accessibility, and recent modification.

方法详细资料

getName

public String getName()

Returns "HEAD".

指定者:

getName 在接口中 HttpMethod

指定者:

getName 在类中 HttpMethodBase

返回:

"HEAD"

从以下版本开始:

2.0

recycle

public void recycle()

已过时。 no longer supported and will be removed in the future version of HttpClient

Recycles the HTTP method so that it can be used again. Note that all of the instance variables will be reset once this method has been called. This method will also release the connection being used by this HTTP method.

指定者:

recycle 在接口中 HttpMethod

覆盖:

recycle 在类中 HttpMethodBase

从以下版本开始:

1.0

readResponseBody

protected void readResponseBody(HttpState state,
                                HttpConnection conn)
                         throws HttpException,
                                IOException

Overrides HttpMethodBase method to not read a response body, despite the presence of a Content-Length or Transfer-Encoding header.

覆盖:

readResponseBody 在类中 HttpMethodBase

参数:

state - the state information associated with this method

conn - the connection used to execute this HTTP method

抛出:

IOException - if an I/O (transport) error occurs. Some transport exceptions can be recovered from.

HttpException - if a protocol exception occurs. Usually protocol exceptions cannot be recovered from.
