SQL2005中的HTTP端点

这个新特点通过HTTP API把HTTP端点暴露给用户,在WINXP SP2和WIN2003上被支持建立一个HTTP端点是非常简单的,如下

CREATE ENDPOINT MyEndpoint?
STATE = STARTED
AS HTTP (
  AUTHENTICATION = (INTEGRATED),
  PATH = '/sql/myendpoint',
  PORTS = (CLEAR) )
FOR SOAP (
  BATCHES = ENABLED,
  WSDL = DEFAULT
)
在上面的案例中我建立一个命名为MyEndpoint的端点,它在http://localhost/sql/myendpoint监听T-SQL语句,你可以使用下面URL测试它
 http://localhost/sql/myendpoint?wsdl.
上面这个URL还可以附加很丰富的参数,具体参见SQL帮助
下面这个例子显示如何通过JAVSCRIPT来调用端点执行T-SQL语句,如下
function SendBatchRequest( strServerName, strUrlPath, strQuery )
{
   var objXmlHttp = null;
   var strRequest = "";

   objXmlHttp = new ActiveXObject( "microsoft.xmlhttp" );
   objXmlHttp.open( "POST", "http://" + strServerName + strUrlPath, false );
   objXmlHttp.setrequestheader( "Content-Type", "text/xml" );
   objXmlHttp.setRequestHeader( "Host", strServerName );

   strRequest = "<SOAP-ENV:Envelope
                           xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/'
                           xmlns:sql='http://schemas.microsoft.com/sqlserver/2004/SOAP'>
                              <SOAP-ENV:Body>
                                 <sql:sqlbatch>
                                    <sql:BatchCommands>" + strQuery + "</sql:BatchCommands>
                                 </sql:sqlbatch>
                              </SOAP-ENV:Body>
                        </SOAP-ENV:Envelope>";

   objXmlHttp.send( strRequest );

   if( objXmlHttp.status == 200 )
      return objXmlHttp.responseXML.xml;
   else
      return "";
}

var response = SendBatchRequest( 'localhost', '/sql/myendpoint', 'Select * from sys.http_endpoints' );
