Calling WEBService using MYSAPSSO2

[Former Member]

Hi,

We would like to create a .NET application connected to our SAP CRM.

From the Portal I get MYSAPSSO2 cookie.

How to set up the CRM server to accept it?

We use portal to SSO, it works, but the webservice is not. Sends back 401 - not authorized.

We have CRM 6.20, NOT 6.40.

Hi Zoltan,

i know it's 4 year ago...but maybe somone limping over the same problem...

What i understand is, you want to consume a WebService on a CRM-System and before you have to authenticate on a Pportal-system. I have the same constellation. I use VS2015 as an Outlook AddIn, a Portal and a SRM Webservice.

Anyway... here is my solution:

1. Get the cookie MYSAPSSO2 out of the http-stream.

    Private Sub connect()


        Dim req As HttpWebRequest = HttpWebRequest.Create("http://xx-xx-xxx.prod.lokal:55000/irj/portal")
        Dim res As HttpWebResponse
        Dim strCookie As String


        req.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:11.0) Gecko/20100101 Firefox/11.0"
        req.Method = "GET"
        req.Credentials = CredentialCache.DefaultCredentials
        req.CookieContainer = New CookieContainer()
        Try
            res = req.GetResponse()
            strCookie = getMYSAPSSO2(res)
            oZBBP_PD_PO_GETDETAIL.setMYSAOSSO2 = strCookie


        Catch ex As Exception
            MsgBox(ex.Message.ToString)
        End Try


    End Sub

    Private Function getMYSAPSSO2(ByRef response As HttpWebResponse) As String
        Dim cook As Cookie
        Try
            For Each cook In response.Cookies
                If cook.Name = "MYSAPSSO2" Then
                    Return cook.Value
                End If
            Next cook
        Catch ex As Exception
            Return Nothing
        End Try


        Return Nothing


    End Function

Attention:

• Use the HttpWebRequest/HttpWebResponse object... not the MSXML2 object(you dont get the cookie out of it)
• set a CookieContainer on the request

2. Consume the WebService with the MYSAPSSO2 Cookie.

    Public Property getPODetail_HttpWeb() As String


        Set(value As String)
            Dim res As HttpWebResponse


            Dim sEnv As String


            sEnv = "<soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:urn=""urn:sap-com:document:sap:soap:functions:mc-style"">"
            sEnv = sEnv & "<soapenv:Header/>"
            sEnv = sEnv & "<soapenv:Body>"
            sEnv = sEnv & "<urn:BbpPdPoGetdetail>"
            sEnv = sEnv & "<IObjectId>" & value & "</IObjectId>"
            sEnv = sEnv & "</urn:BbpPdPoGetdetail>"
            sEnv = sEnv & "</soapenv:Body>"
            sEnv = sEnv & "</soapenv:Envelope>"


            Dim req As HttpWebRequest = HttpWebRequest.Create(e71_URL)
            Dim strCokkie As String = "cookie: MYSAPSSO2=" & MYSAPSSO2
            With req
                Try
                    .Headers.Add("Accept-Encoding:gzip,deflate")
                    .Headers.Add("SOAPAction:Retrieve")
                    .Headers.Add(strCokkie)


                    .Method = "POST"
                    .Credentials = CredentialCache.DefaultCredentials
                    .UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:11.0) Gecko/20100101 Firefox/11.0"
                    .Host = "xx-xx-xxx.prod.lokal:8096"
                    .ContentType = "text/xml;charset=UTF-8"


                    Dim newStream As New StreamWriter(.GetRequestStream(), Encoding.UTF8)
                    newStream.Write(sEnv)
                    newStream.Flush()
                    newStream.Close()


                    res = .GetResponse()


                    Dim sr As StreamReader
                    Dim strResult As String = ""


                    Dim streamStream As Stream
                    streamStream = res.GetResponseStream()
                    streamStream = New GZipStream(streamStream, CompressionMode.Decompress)


                    sr = New StreamReader(streamStream, Encoding.UTF8)
                    strResult = sr.ReadToEnd.Trim
                    sr.Close()


                    document.LoadXml(strResult)


                    req = Nothing


                Catch ex As Exception
                    MsgBox(ex.Message.ToString)
                End Try


            End With


            req = Nothing


        End Set
        Get
            Return Nothing
        End Get
    End Property

Attention:

• set the default credentials
• you have to decode the response stream

be happy...

Hi,

Sorry, but I misstyped version. We have BBPCRM 4.0:

SAP_BASIS 620 0054 SAPKB62054

SAP_ABA 620 0054 SAPKA62054

BBPCRM 400 0008 SAPKU40008

PI_BASIS 2006_1_620 0001 SAPKIPYK01

ST-PI 2005_1_620 0007 SAPKITLQG7

ST-A/PI 01J_CRM400 0000 -

VIRSANH 520_620 0009 SAPK-52109INVIRSANH

The SSO is working using portal links after I log into the portal.

If I try to use a function through WebService, providing the MYSAPSSO2 cookie -> it fails.
