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 = 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' );
