How to post a JSON object using a Dictionary? RRS feed

  • Question

  • Here is the JSON that needs to be posted.

    { "getcart": { "version": "1.0", "account": "6566", "username": "112", "password": "xxxxxxxx", "cartid": "57044d79", } }

    Dim jsonPost As New JsonPost("https://www.example.aspx")
    Dim dictData As New Dictionary(Of String, Object)
    dictData.Add("version", "1.0")
    dictData.Add("account", "6566")
    dictData.Add("username", "112")
    dictData.Add("password", "xxxxxxxx")
    dictData.Add("cartid", "57044d79")
    Dim json As JObject = JObject.Parse(JsonPost.postData(dictData))
    Dim response As String = JsonPost.postData(dictData)

    The error I'm getting:

           Dim Uri As String = "https://www."
           Dim data = Encoding.UTF8.GetBytes(JsonData)
           Dim result_post = SendRequest(New Uri(Uri), data, "application/json", "POST")
         Private Function SendRequest(uri As Uri, jsonDataBytes As Byte(), contentType As String, method As String) As String
            Dim req As WebRequest = WebRequest.Create(uri)
            req.ContentType = contentType
            req.Method = method
            req.ContentLength = jsonDataBytes.Length

            Dim stream = req.GetRequestStream()
            stream.Write(jsonDataBytes, 0, jsonDataBytes.Length)

            Dim response = req.GetResponse().GetResponseStream()

            Dim reader As New StreamReader(response)
            Dim res = reader.ReadToEnd()

            Return res
        End Function
