JSON從C＃發布到ColdFusion API

Question

我正在嘗試連接到需要JSON的API，並且不斷收到500個內部錯誤。 再次閱讀連接說明后，看來我的問題源於以下事實：我傳遞了一個字符串，而API正在尋找以字符串作為值的表單字段。 如何在C＃中以編程方式完成？ 以下不適用於我。

 //Create JSON string to send to iCohere API using POST
        var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://www.api,url");
        httpWebRequest.ContentType = "application/x-www-form-urlencoded";
        httpWebRequest.Method = "POST";


        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = new JavaScriptSerializer().Serialize(new
            {
                ClientID = ConfigurationManager.AppSettings["ClientID"],
                AuthCode = ConfigurationManager.AppSettings["AuthCode"],
                cSeq = ConfigurationManager.AppSettings["cSeq"],
                LastName = "Fett",
                FirstName = "Bubba",
                EmailAddress = "dec18@comingsoon.com",
                EventCode = "WEBINAR"
            });

            TextBox iCohereForm = new TextBox();
            iCohereForm.ID = "JSONAPISTR";
            iCohereForm.Text = json;
            streamWriter.Write(iCohereForm);

        }


        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();

        }

更新：此問題的適當位置是代碼審查

問題是您試圖將UI控件對象放入StreamWriter中。 並在發出HTTP請求期間使用此內存流數據。
另外，您正在以錯誤的方式執行HTTP請求。 正確的是：

string json = new JavaScriptSerializer().Serialize(new
        {
            ClientID = ConfigurationManager.AppSettings["ClientID"],
            AuthCode = ConfigurationManager.AppSettings["AuthCode"],
            cSeq = ConfigurationManager.AppSettings["cSeq"],
            LastName = "Fett",
            FirstName = "Bubba",
            EmailAddress = "dec18@comingsoon.com",
            EventCode = "WEBINAR"
        });

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://api url");
requst.Method = "POST";
requst.ContentType = "application/json";
byte[] _byteVersion = Encoding.ASCII.GetBytes(json);

request.ContentLength = _byteVersion.Length

Stream stream = request.GetRequestStream();
stream.Write(_byteVersion, 0, _byteVersion.Length);
stream.Close();

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

using (StreamReader reader = new StreamReader(response.GetResponseStream()))
    {
        Console.WriteLine(reader.ReadToEnd());
    }
