tomcat 如何从SQL Server发出HTTP请求？

我想从SQL服务器发送HTTP请求到Tomcat服务器。我已经在Tomcat服务器中安装了SQL Server 2012 Express和非.NET应用程序。我已经通过了Make a HTTP request from SQL server
正如上面的文章中所说，“COM对象WinHttp.WinHttpRequest.5.1必须安装在服务器上，一些典型的变体是WinHttp.WinHttpRequest.5”。我已经从winhttp download link下载了winhttp.zip，在zip文件夹中找到了winhttp.dll，并将其粘贴到C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER2\MSSQL\Binn中，就像在msdn link中建议的那样。
根据相同的建议，我在SSMS中执行了以下行：

sp_addextendedproc 'GetHttp',
 'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER2\MSSQL\Binn\winhttp.dll';

我还在SSMS中执行了以下代码，如“从SQL Server链接发出HTTP请求”中所述：

Alter function GetHttp
(
@url varchar(8000)      
)
returns varchar(8000)
as
BEGIN
DECLARE @win int 
DECLARE @hr  int 
DECLARE @text varchar(8000)

EXEC @hr=sp_OACreate 'WinHttp.WinHttpRequest.5.1',@win OUT 
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win

EXEC @hr=sp_OAMethod @win, 'Open',NULL,'GET',@url,'false'
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win

EXEC @hr=sp_OAMethod @win,'Send'
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win

EXEC @hr=sp_OAGetProperty @win,'ResponseText',@text OUTPUT
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win

EXEC @hr=sp_OADestroy @win 
IF @hr <> 0 EXEC sp_OAGetErrorInfo @win 

RETURN @text
END

然后我得到错误
Msg 2010，级别16，状态1，过程GetHttp，第2行
无法对“GetHttp”执行alter，因为它是不兼容的对象类型。
我不知道如何调用函数来发送HTTP请求。我假设它是类似于GetHttp('http://www.google.co.in/')的东西。
我错过了什么？

我也得到了另一个答案。我创建了如下的过程

CREATE procedure HTTP_Request( @sUrl varchar(200))
As

Declare
@obj int
,@hr int
,@msg varchar(255)

 exec @hr = sp_OACreate 'MSXML2.ServerXMLHttp', @obj OUT
if @hr <> 0 begin Raiserror('sp_OACreate MSXML2.ServerXMLHttp.3.0
failed', 16,1) return end

exec @hr = sp_OAMethod @obj, 'open', NULL, 'POST', @sUrl, false
if @hr <>0 begin set @msg = 'sp_OAMethod Open failed' goto eh end

exec @hr = sp_OAMethod @obj, 'setRequestHeader', NULL, 'Content-Type',
'application/x-www-form-urlencoded'
if @hr <>0 begin set @msg = 'sp_OAMethod setRequestHeader failed' goto
eh end

exec @hr = sp_OAMethod @obj, send, NULL, ''
if @hr <>0 begin set @msg = 'sp_OAMethod Send failed' goto eh end

 exec @hr = sp_OADestroy @obj
return
eh:
exec @hr = sp_OADestroy @obj
Raiserror(@msg, 16, 1)
return
GO

我用url调用了存储过程

USE [master]
GO

 DECLARE    @return_value int

EXEC    @return_value = [dbo].[HTTP_Request]
    @sUrl = N'url'

SELECT  'Return Value' = @return_value

GO

谢谢你们让我做这个。

这真的帮助了我@niren。
我想我会把我的修正案，把它放在标量函数，并允许你得到服务响应。唯一的缺点是标量函数不能raiserrors，所以有一些考虑捕捉其他地方。

CREATE function [dbo].[fn_HttpPOST]
(
    @sUrl varchar(8000)      
)
returns varchar(8000)
as
BEGIN
    DECLARE @obj int 
    DECLARE @hr  int 
    DECLARE @msg varchar(8000)    

    exec @hr = sp_OACreate 'MSXML2.ServerXMLHttp', @obj OUT
    if @hr <> 0 begin set @Msg = 'sp_OACreate MSXML2.ServerXMLHttp.3.0 failed' return @Msg end

    exec @hr = sp_OAMethod @obj, 'open', NULL, 'POST', @sUrl, false
    if @hr <>0 begin set @msg = 'sp_OAMethod Open failed' goto eh end

    exec @hr = sp_OAMethod @obj, 'setRequestHeader', NULL, 'Content-Type', 'application/x-www-form-urlencoded'
    if @hr <>0 begin set @msg = 'sp_OAMethod setRequestHeader failed' goto eh end

    exec @hr = sp_OAMethod @obj, send, NULL, ''
    if @hr <>0 begin set @msg = 'sp_OAMethod Send failed' goto eh end

     EXEC @hr=sp_OAGetProperty @Obj,'ResponseText',@msg OUTPUT
    IF @hr <> 0 EXEC sp_OAGetErrorInfo @Obj

    exec @hr = sp_OADestroy @obj

    RETURN @msg

    eh:
    exec @hr = sp_OADestroy @obj
    return @msg
END

我通过powershell得到了答案。我所做的是在sql server中打开powershell，然后在powershell中执行以下代码。

$http_Request= New-Object system.Net.WebClient;
$Result = $http_Request.downloadString("url")

这里最灵活的方法是使用CLR用户定义函数，您可以简单地在C#中定义如下：

[Microsoft.SqlServer.Server.SqlFunction]
public static SqlString http(SqlString url)
{
    var wc = new WebClient();
    var html = wc.DownloadString(url.Value);
    return new SqlString (html);
}

正确的方法是构建一个CLR，它将包含一个C#代码来发送http/s请求，因为我们想避免内存泄漏和安全问题，这是使用像sp_OACreate这样的旧方法可能导致的。
例如：

var request = 
   (HttpWebRequest)WebRequest.Create("http://www.example.com. /recepticle.aspx");
    var postData = "thing1=hello";
    postData += "&amp;amp;amp;amp;amp;thing2=world";
    var data = Encoding.ASCII.GetBytes(postData);
    request.Method = "POST";
   request.ContentType = "application/x-www-form-urlencoded";
   request.ContentLength = data.Length;
   using (var stream = request.GetRequestStream())
    {
    stream.Write(data, 0, data.Length);
     }
    var response = (HttpWebResponse)request.GetResponse();
   var responseString = new     StreamReader(response.GetResponseStream()).ReadToEnd();`

使用sp_OACreate不太安全，而CLR可以由您签名和检查。

有了这些代码，您可以通过Httpprequest从网页中读取Html代码或运行SOAP Web服务。
从SQLserver发出HTTP请求。
通过SQL Server发送HTTP请求。
从SQL Server TSQL存储过程调用SOAP Web服务。
将Http响应保存到文件。
