sqloptions:hostname 标头元素

sqloptions:hostName 登录选项使客户端可指定登录的主机名，例如：

<SOAP-ENV:Header
  xmlns:SOAP-ENV="https://schemas.xmlsoap.org/soap/envelope/"
  xmlns:sqloptions="https://schemas.microsoft.com/sqlserver/2004/SOAP/Options">
    <sqloptions:hostname 
          SOAP-ENV:mustUnderstand="1"
          value="hostName"/>
    
</SOAP-ENV:Header>

sqloptions:hostName 登录选项显示为 SOAP 标头。它由一个元素组成，称为 sqloptions:hostName。此元素有一个必需的属性：value（文本值）。它可以为登录帐户设置 host name 。此值显示在 sys.sysprocesses 兼容性视图的 hostname 列中。

在一次请求中只能出现一个 sqloptions:hostName 选项实例。该选项无法在响应中显示。多个选项实例将会生成错误。

服务器可以限制 sqloptions:hostName 值的识别值的范围。如果客户端提交的值超出了允许的范围，则服务器将自行截断该值，截断方式不定。

如果使用 SOAP 会话，则必须在与 sqloptions:sqlsession initiate 属性相同的请求中显示此选项。如果此选项显示在具有 sqloptions:sqlSession 标头（但此标头不包含 initiate 属性）的任意请求中，将生成一个错误。

下列是 sqloptions:hostName 的架构片断：

<xs:element name="hostName" form="qualified">
    <xs:annotation>
        <xs:documentation>
            Set the host name for the login.
        </xs:documentation>
    </xs:annotation>
    <xs:complexType>
        <xs:attribute use="required" name="value" type="xs:string" form="unqualified">
            <xs:annotation>
                <xs:documentation>
                    The host name to set for the login.
                </xs:documentation>
            </xs:annotation>
        </xs:attribute>
    </xs:complexType>
</xs:element>

示例

以下是在 SOAP 请求和响应消息中使用 sqloptions:hostname 标头的示例。

请求

<SOAP-ENV:Envelope xmlns:SOAP-ENV="https://schemas.xmlsoap.org/soap/envelope/"
                   xmlns:sql="https://schemas.microsoft.com/sqlserver/2004/SOAP"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                   xmlns:sqlparam="https://schemas.microsoft.com/sqlserver/2004/SOAP/types/SqlParameter"
                   xmlns:sqlsoaptypes="https://schemas.microsoft.com/sqlserver/2004/SOAP/types"
                   xmlns:sqloptions="https://schemas.microsoft.com/sqlserver/2004/SOAP/Options">
  <SOAP-ENV:Header>
    <sqloptions:hostName SOAP-ENV:mustUnderstand="1" value="recep35" />
  </SOAP-ENV:Header>
  <SOAP-ENV:Body>
    <sql:sqlbatch>
      <sql:BatchCommands>
        SELECT hostname FROM sysprocesses 
        WHERE spid=@@spid AND hostName='recep35'
      </sql:BatchCommands>
    </sql:sqlbatch>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

    </sql:sqlbatchResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
