I'm trying to perform the same scenario as in the following link; Create a SSIS Script Component as a Data Source that uses a pre-existing HTTP Connection Manager to retreive a page with GET and emit rows into the Data Flow pipeline.


My target platform is SQL Server 2008 and therefore C#. The MSDN documentation gives examples of File and SQL Connection Managers but not HTTP ones.


The specific problem is that I can NOT figure out why there's no HttpClientConnection constructor in my current context. The MSDN documentation of that class does not seem to apply in the case of Script Components and translating this to something useful is apparently beyond me.


My non-working code looks like this -

using System;  
using System.Data;  
using System.Text;  

using Microsoft.SqlServer.Dts.Pipeline.Wrapper;  
using Microsoft.SqlServer.Dts.Runtime.Wrapper;  

public class ScriptMain : UserComponent  
    public override void AcquireConnections()  
        IDTSConnectionManager100 connMgr = this.Connections.MyWebServer;  
    public override void PreExecute()  

       HttpClientConnection clientConn = new HttpClientConnection(connMgr));  

       Byte[] buffer = clientConn.DownloadData();  
       String Document = Encoding.ASCII.GetString(buffer);  

What am I missing?

  • I'll try to look at this tonight but take a peek at how Matt handles an OLE DB CM Might need to take a similar approach – billinkc Feb 9 '15 at 19:03
  • I've seen plenty of examples with DB connections- HTTP Connection Managers are apparently the odd man out. – Jeff Sacksteder Feb 9 '15 at 21:43
  • I got nothing. Apparently I'm the first person to ever do this. – Jeff Sacksteder Feb 12 '15 at 0:15
  • While I beat my head against some solid surfaces to get this working, what are you trying to do? I've done a bit with SSIS, used web services, etc but haven't gone this route to do things. If nothing else, the more we talk, the less apt I am to get distracted by squirrels – billinkc Feb 12 '15 at 4:24
  • The JSON src component on Codeplex doesn't install correctly, so until I get that working I thought I'd just use a script component and a http connection manager. – Jeff Sacksteder Feb 12 '15 at 15:48

i know it's been a while since the question but i found a possible solution.

This link provides an explanation and examples of how to use the connections available in the connection manager enabled for the Script Component in the SSIS https://msdn.microsoft.com/en-us/library/ms136060.aspx

The portion of code that we are interested is this:

IDTSConnectionManager100 connMgr;
HttpClientConnection100 hcc;

IDTSComponentMetaData100 compMetadata = this.ComponentMetaData; //Just for output purposes.       

connMgr = this.Connections.MyWebServer;

hcc = (HttpClientConnection100)cm.AcquireConnection(null);
compMetadata.FireInformation(1, "Message: ", "URL: " + hcc.ServerURL + " User: " + hcc.ServerUserName + " Pwd: " + hcc.GetServerPassword(), "", 0, ref fail);
