Question

Magento has an API and it seems some people are using it via VB.NET but I cannot get it to work after trying for many hours.

I’m on Magento 1.7.0.2
Trying to get a VB.NET app working with the API.
I’m using the WS-I compliant web service setting.

Error 1 Custom tool error: Unable to import WebService/Schema. Unable to import binding ‘Mage_Api_Model_Server_Wsi_HandlerBinding’ from namespace ‘urn:Magento’. The operation ‘catalogProductAttributeRemove’ on portType ‘Mage_Api_Model_Server_Wsi_HandlerPortType’ from namespace ‘urn:Magento’ had the following syntax error: The operation has no matching binding. Check if the operation, input and output names in the Binding section match with the corresponding names in the PortType section. d:\Documents\Visual Studio 2010\Projects\Mage\Mage\My Project\Settings.settings 1 1 Mage

if I try to add it as a Service Reference (instead of a Web Reference) I get a different set of errors.

Cannot import wsdl:binding
Cannot import wsdl:port
Cannot import wsdl:portType

Error 5 Custom tool error: Failed to generate code for the service reference ‘ServiceReference1’. Please check other error and warning messages for details. d:\Documents\Visual Studio 2010\Projects\Mage\Mage\Service References\ServiceReference1\Reference.svcmap 1 1 Mage

Can someone give me very explicit instruction/code on how to make a call and get a result? I can’t even seem to get the initial configuration correct. I’ve downloaded some code others have provided online, but if doesn’t work–probably because it was for a earlier version.

Answer 1

Function getHTTPStream() As String
    Dim myh As HttpWebRequest = _
    HttpWebRequest.Create("http://yourmagentoweb/soap/api/?wsdl")
    myh.Timeout = 30000
    myh.UserAgent = "Test"
    Dim myR As HttpWebResponse = myh.GetResponse()
    Dim myEnc As Encoding = Encoding.GetEncoding(1252)
    Dim mySr As StreamReader = New StreamReader(myR.GetResponseStream(), myEnc)

    Return mySr.ReadToEnd()
End Function

That code needs tweaking obviously- i have not got time to prettify this stuff

from Abid Hussain’s link

1. Using wdsl tool I created a .vb source file by calling:

wsdl /language:VB /out:MageProxyClass.vb http:///api/v2_soap?wsdl

2. Afterwards I used the VB Comand Line Editor to compile the sourcefile into a dll.

vbc /out:MageProxyClass.dll /t:library
/r:System.XML.dll,System.Web.Services.dll MageProxyClass.vb

3. Finally I was able to create an instance of MagentoService class defined in my MageProxyClass.dll

Private WithEvents msvc As New MagentoService() 

4. Example:

 Public Class main
    Private WithEvents msvc As New MagentoService()
    Private ssid As String
    Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ListBox1.Items.Clear()
        ListBox1.Items.Add("Trying to connect")
        msvc.loginAsync("xxxx", "xxxxxxxxxxxxxxxx")
    End Sub

    Public Sub MageLoginComplete(ByVal sender As System.Object, ByVal e As loginCompletedEventArgs) Handles msvc.loginCompleted
        ListBox1.Items.Add("Login completed")
        ssid = e.Result
        ListBox1.Items.Add(String.Concat("Session ID: ", ssid))
    End Sub
End Class
