我正尝试通过JSON格式的c#HttpWebRequest将Tin Can Statements发布到Scorm Cloud LRS。但是我总是得到错误400.验证是正确的,所以JSON有什么问题?我已尝试编码为UTF8,但仍然没有骰子
以下是所需的代码和凭据:
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("https://cloud.scorm.com/ScormEngineInterface/TCAPI/RCFZ5D8GXU/sandbox/");
httpWebRequest.ContentType = "application/json; charset=UTF-8";
httpWebRequest.Method = "POST";
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
String autorization= "Basic " + Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes("RCFZ5D8GXU222" + ":" + "YQA3VfX1NiuYkKXEEzkKu723NwejpwNkB6x0Vhg3"));
httpWebRequest.Headers.Add("Authorization", autorization);
httpWebRequest.Headers.Add("X-Experience-API-Version", "1.0.1");
string jsonText = "{"+
" \"actor\": {"+
" \"mbox\": \"mailto:Steeno@gmail.com\","+
" \"name\": \"Austin Glatt\","+
" \"objectType\": \"Agent\""+
"},"+
"\"verb\": {"+
" \"id\": \"http://adlnet.gov/expapi/verbs/attempted\","+
" \"display\": {"+
" \"en-US\": \"attempted\""+
" }"+
"},"+
"\"object\": {"+
" \"id\": \"http://www.example.com/tincan/activities/cMjKwAGI\","+
" \"objectType\": \"Activity\","+
" \"definition\": {"+
" \"name\": {"+
" \"en-US\": \"Part Removal\""+
" },"+
" \"description\": {"+
" \"en-US\": \"On Engine 155\""+
" }"+
" }"+
"}"+
"}";
byte [] jsonData = System.Text.Encoding.UTF8.GetBytes(jsonText);
Debug.Log(System.Text.Encoding.UTF8.GetString(jsonData));
httpWebRequest.ContentLength = jsonData.Length;
using (var streamWriter = httpWebRequest.GetRequestStream())
{
streamWriter.Write(jsonData,0,jsonData.Length);
streamWriter.Flush();
streamWriter.Close();
}
try
{
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
Debug.Log("POST result"+result);
}
}
catch(WebException ex)
{
if (ex.Response != null)
{
Debug.Log(ex.Message);
foreach(DictionaryEntry d in ex.Data)
Debug.Log(d.ToString());
string errorDetail = string.Empty;
using (StreamReader streamReader = new StreamReader(ex.Response.GetResponseStream(), true))
{
errorDetail = streamReader.ReadToEnd();
Debug.Log(errorDetail);
}
}
}

我认为您错过了网址上的“语句”,您的请求应该是:
https://cloud.scorm.com/ScormEngineInterface/TCAPI/RCFZ5D8GXU/sandbox/statements
如有人关心的原始答案:
您似乎发布了0.95或1.0.x语句,但您似乎没有设置X-Experience-API-Version标头,因此LRS可能会将其解释为0.9语句,该语句无效
我强烈建议使用库来构建请求以及请求的内容。我们在这里有一个:
