Hello Experts,
We are trying to call the REST API to get some objects from the application server. The code we have can authenticate fine against the app server (we verify this by seeing a unique session ID), however when we try to run a "simple" POST to get some entities, the app server returns HTML instead of JSON. The HTML itself contains an error message saying "Javascript is disabled". The query is the same one that swagger generates.
For this simple example, we want to retrieve all Person objects. We have a ASP.NET web application, where clicking a button calls the API to get the objects.
Private Function GetWebSession() As String
Try
Dim OutputSessionID As String
Dim inputData As String
inputData = "{""AuthString"": ""Module=DialogUser;User=xxxxx;Password=xxxxx""}"
Dim url As String = GetSettings.URLLogin
Dim HttpRequest As System.Net.HttpWebRequest = CType(System.Net.HttpWebRequest.Create(url), System.Net.HttpWebRequest)
HttpRequest.Method = "Post"
HttpRequest.Accept = "application/json"
HttpRequest.Timeout = 300000
Dim inputEncoded = Encoding.ASCII.GetBytes(inputData)
HttpRequest.GetRequestStream.Write(inputEncoded, 0, inputEncoded.Length)
Dim cookie As New Cookie
cookie.Domain = "xxxxxxx.xx.xx.com"
cookie.Name = "SessionVariable"
cookie.Value = "wsession"
objcontainer.Add(cookie)
HttpRequest.CookieContainer = objcontainer
Dim HttpResponse As System.Net.HttpWebResponse = CType(HttpRequest.GetResponse(), System.Net.HttpWebResponse)
Dim receiveStream As Stream = HttpResponse.GetResponseStream()
Dim readStream As New StreamReader(receiveStream, Encoding.UTF8)
Dim serializer As New System.Web.Script.Serialization.JavaScriptSerializer()
Dim jsonobject = serializer.DeserializeObject(readStream.ReadToEnd())
OutputSessionID = jsonobject("sessionId")
jsonobject = Nothing
readStream = Nothing
receiveStream = Nothing
HttpRequest = Nothing
HttpResponse = Nothing
Return OutputSessionID
Catch ex As Exception
Throw ex
End Try
End Function
Private Sub btnfilter_Click(sender As Object, e As EventArgs) Handles btnfilter.Click
Try
Dim url As String = "http://xxxxxxx.xxx.xxx.com:80/AppServer/api/entities/Person?loadType=Default"
Dim HttpRequest As System.Net.HttpWebRequest = CType(System.Net.HttpWebRequest.Create(url), System.Net.HttpWebRequest)
HttpRequest.Method = "Post"
HttpRequest.ContentType = "application/json"
HttpRequest.Timeout = 300000
HttpRequest.ContentLength = 0
HttpRequest.CookieContainer = objcontainer
)
Dim HttpResponse As System.Net.HttpWebResponse = CType(HttpRequest.GetResponse(), System.Net.HttpWebResponse)
Dim receiveStream As Stream = HttpResponse.GetResponseStream()
Dim readStream As New StreamReader(receiveStream, Encoding.UTF8)
Dim serializer As New System.Web.Script.Serialization.JavaScriptSerializer()
Dim jsonobject = serializer.DeserializeObject(readStream.ReadToEnd())
readStream = Nothing
receiveStream = Nothing
HttpRequest = Nothing
HttpResponse = Nothing
Catch ex As Exception
lblnorecordsfound.Text = ex.Message
End Try
End Sub
Any help on why this is would be much appreciated
