【问题描述】:
我想按照我发送的方式使用此代码将一些 json 数据发送到远程服务器(Rest,不受我控制):
我先创建url和请求方法:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(gUrlDot);
request.Method = "POST";
Dictionary<String, String> lDictionary = new Dictionary<String, String>();
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
Dot lDot= new Dot();
serviceContext lserviceContext = new serviceContext();
items litems = new items();
lDot.rad = pClient;
lDictionary.Add("companyId", "00230");
lDictionary.Add("treatmentDate", lGlobals.FormatDateYYYYMMDD());
lDictionary.Add("country", "FR");
lDictionary.Add("language", "fr");
lDictionary.Add("Id", "test");
litems.contextItem = lDictionary;
lDot.serviceContext = lserviceContext;
lDot.serviceContext.items = litems;
String Input=_Tools.JsonSerializer(lDot);
log.Debug("Input Dot " + Input);
Byte[] byteArray = encoding.GetBytes(Input);
request.ContentLength = byteArray.Length;
request.ContentType = @"application/json";
using (Stream dataStream = request.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
}
long length = 0;
当我到达这里时,它会因执行而崩溃:错误 500!
try
{
using (var response = (HttpWebResponse)request.GetResponse())
{
length = response.ContentLength;
string output = response.ToString();
lTrace.AppendLine("-Flux Json recu => " + response.StatusCode + " " + length);
log.Debug("Output Dot " + output);
}
log.Info(LogsHelper.LogHeader("End processing Get list ", pClient, Service.SrvGetList, "", lResponse.StatusCode, lResponse.StatusLabel, lResponse.ResponseObject, ref lTrace));
}
catch (Exception ex)
{
lResponse.StatusCode = StatusCodes.ERROR_COMMUNICATION;
log.Error(LogsHelper.LogHeader("End processing Get list", pClient, Service.SrvGetList, "", lResponse.StatusCode, ex.Message, lResponse.ResponseObject, ref lTrace));
}
return lResponse;
}
我在这里错过了什么?
【问题讨论】:
-
您是否从服务器收到任何消息错误(例如使用 fiddler 进行调试)? Http状态码“500”表示服务器内部错误,如果你的请求有效,错误可能来自远程服务器。
