SQL2005中的HTTP端点

SQL2005提供了一个新的执行存储过程或者T-SQL的方法,它可以以WEB服务的方式发布到服务器上,而无须使用IIS

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 = STARTEDAS 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' );
