Hi All,

I Believe my code is good, but I'm only getting a 'Fail'.

I am using Visual Studio 2015 behind my District Firewall, but I am have admin privileges for Aeries and on the network.

Here is my code:

    <script>
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
  }

xmlhttp.onreadystatechange = function ()
  {
    if (xmlhttp.readyState == 4 && xmlhttp.status == 200)
    {
    document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
    }
    else { document.getElementById("myDiv").innerHTML = "Fail"; }
}

xmlhttp.setRequestHeader("Accept", "text/xml");
xmlhttp.send();

}
    </script>
</head>
<body>

    <h2>AJAX</h2>
    <button type="button" onclick="loadXMLDoc()">Request data</button>
    <div id="myDiv"></div>

</body>

I think I'm seeing 2 issues that you may be facing.  The first is that your script, running inside a simple HTML page, is probably running through regular HTTP.  Your request is to HTTPS and browsers will prevent cross-domain/protocol requests like that.  Changing to "http://demo.aeries.net/aeries.net/api/v2/schools" will work, but not really.  A request like that from your local web page will go through (use Fiddler and you will see the request and response), but the results won't be returned to the object XML object.  I think the browser may be blocking the content for the same reason as the HTTPS issue.  You are requesting content from a different domain.  And for security reasons, browsers don't like that.  To confirm this, I tested against a local instance of Aeries.net I have on my dev machine and the script works perfectly.

 

So in summary, you can't use javascript to do what you are trying to do.  You will need to create server-side code (or an application) where the browser's security restrictions won't inhibit your code.  Here is a sample "xmlHTTP" class written in VB.net to give you an example of how you would do this server-side.

 

 

Imports Microsoft.VisualBasic

Imports System.XML

 

Public Class XMLHTTP

 

                Protected _URL As String = ""

                Public Property URL() As String

                                Get

                                                Return _URL

                                End Get

                                Set(ByVal value As String)

                                                _URL = value

                                End Set

                End Property

 

                Public Sub New()

 

                End Sub

 

                Public Sub New(ByVal URL As String)

                                Me.URL = URL

                End Sub

 

                Public Function ReturnXML() As XmlDocument

 

                                Dim HttpWebReq As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(Me.URL)

                                HttpWebReq.Method = "GET"

 

                                Dim hwrp As System.Net.HttpWebResponse = CType(HttpWebReq.GetResponse(), System.Net.HttpWebResponse)

                                Dim s As System.IO.Stream = hwrp.GetResponseStream()

                                Dim sr As System.IO.StreamReader = New System.IO.StreamReader(s)

                                Dim responseText As String = sr.ReadToEnd()

 

                                Dim xmlDoc As New XmlDocument()

                                If responseText.Length > 0 Then              'If nothing is returned, the following statement would generate an exception, so make sure we've got something

                                                xmlDoc.LoadXml(responseText)

                                End If

                                hwrp.Close()

                                Return xmlDoc

 

                End Function

 

                Public Function ReturnXML(ByVal URL As String) As XmlDocument

 

                                Me.URL = URL

                                Return ReturnXML()

 

                End Function

 

End Class

Thanks Cam,

This is what I have now in Visual Studio - currently getting a 404

  Function ReturnXML() As String
        Try
            MsgBox("1")

            Dim responseData As String = ""

            Dim cookieJar As New Net.CookieContainer()
            Dim hwrequest As Net.HttpWebRequest = Net.WebRequest.Create("https://demo.aeries.net/api/schools")
            Dim username As String
            Dim password As String

            username = "admin"
            password = "admin"
            Dim networkCredential As New NetworkCredential(username, password)

            hwrequest.CookieContainer = cookieJar
            hwrequest.Accept = "text/xml,*/*"
            hwrequest.AllowAutoRedirect = True
            hwrequest.UserAgent = "http_requester/0.1"
            hwrequest.Timeout = 60000
            hwrequest.Method = "GET"

            MsgBox("2")
            Dim hwresponse As Net.HttpWebResponse = hwrequest.GetResponse()
            MsgBox(hwresponse)
            If hwresponse.StatusCode = Net.HttpStatusCode.OK Then
                Dim responseStream As IO.StreamReader =
                  New IO.StreamReader(hwresponse.GetResponseStream())
                responseData = responseStream.ReadToEnd()
                Response.Text = responseData

            End If
            hwresponse.Close()
        Catch ex As Exception


        End Try
    End Function

On a similar topic, Does the API only accept certificates?  If I am doing something for my district from inside my district domain, can I not use name/password? or would I still need a certificate?

The cert is technically the only published, publicly documented way.

Is the certificate issued from our IIS or through Aeries.net?

It's all through Aeries.net on the "API Security" page.

Ok, found it. I have created a test certificate and see the certificate key. Can this be exported as a.cer file?

It's not a real "Certificate".  It's just a unique, random character string you use in your requests.  Coding that in a request header is a lot easier than trying to install a real certificate, deal with trusting CAs, and creating code to use a real cert.

Ok, so now I'm trying it on my own database. I don't know if my trying this from within our domain makes a difference:

I just realized we use Windows Authentication. I bet that's a problem I'm having. When I paste the URL in the browser, the windows authtentication window pops up

Your header information is wrong.  You named the certificate information the wrong name.  Please see the documentation for the proper name.

Windows authentication could also be a problem.  This is why we recommend that you use your parent/student portal for API access, not your internal admin/teacher instance of Aeries.net.
