When you make a HEAD request like this, the server doesn't return an actual response as it would for a GET or POST request.
当您这样生成一个HEAD请求时，服务器并不会像对GET或POST请求一样返回一个真正的响应。
For example, the namespace "urn:oasis:names:tc:SAML:1.0:action:ghpp" defines the get/head/put/post http actions that SAML operations use.
例如，名称空间 "urn:oasis:names:tc:SAML:1.0:action:ghpp"定义了 SAML操作中使用的get/head/put/posthttp操作。
