[英]The remote server returned an error: (500) Internal Server Error on website
I have a problem with running website via http://datalan.aspone.cz/ where data in a red table were still not available and as result is returned error message below "Error close The remote server returned an error: (500) Internal Server Error." 我通过http://datalan.aspone.cz/运行网站时遇到问题,其中红色表中的数据仍然不可用,并且返回结果为错误消息“错误关闭”,远程服务器返回错误:(500)内部服务器错误。”
Also website is already running on a localhost and there is no trouble. 网站也已经在本地主机上运行,没有问题。
I don't know where I made mistake but I would greatly appreciate it if someone helps solve these case. 我不知道我在哪里犯了错误,但是如果有人帮助解决这些问题,我将不胜感激。
I attach the code below: 我附上以下代码:
public List<Data> Generate()
{
List<Data> data = new List<Data>();
WebRequest request = WebRequest.Create("http://192.168.1.100/st0.xml");
request.Credentials = new System.Net.NetworkCredential("admin", "admin");
WebResponse response;
Stream ReceiveStream;
XmlTextReader reader = null;
try
{
response = request.GetResponse();
ReceiveStream = response.GetResponseStream();
reader = new XmlTextReader(ReceiveStream);
}
catch (WebException ex)
{
response = ex.Response;
ReceiveStream = response.GetResponseStream();
}
List<Tuple<string, string, int>> values = new List<Tuple<string, string, int>>();
while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element)
{
switch (reader.Name)
{
case "ia0":
double temp = Convert.ToDouble(reader.ReadString()) / 10;
values.Add(new Tuple<string, string, int>(String.Format(temp.ToString() + " °C"), "Temperature", 0));
break;
case "ia1":
double vol = Convert.ToDouble(reader.ReadString()) / 10;
values.Add(new Tuple<string, string, int>(String.Format(vol.ToString() + "V"), "Voltage", 1));
break;
case "di0":
values.Add(new Tuple<string, string, int>(reader.ReadString(), "INPD0", 2));
break;
case "di1":
values.Add(new Tuple<string, string, int>(reader.ReadString(), "INPD1", 3));
break;
case "di2":
values.Add(new Tuple<string, string, int>(reader.ReadString(), "INPD2", 4));
break;
case "di3":
values.Add(new Tuple<string, string, int>(reader.ReadString(), "INPD3", 5));
break;
case "out0":
values.Add(new Tuple<string, string, int>(reader.ReadString(), "OUT0", 6));
break;
case "out1":
values.Add(new Tuple<string, string, int>(reader.ReadString(), "OUT1", 7));
break;
case "out2":
values.Add(new Tuple<string, string, int>(reader.ReadString(), "OUT2", 8));
break;
case "out3":
values.Add(new Tuple<string, string, int>(reader.ReadString(), "OUT3", 9));
break;
}
}
}
for (int i = 0; i < values.Count; i++)
{
for (int j = 0; j < values.Count; j++)
{
if (i == values[j].Item3)
{
data.AddRange(new List<Data> { new Data { Type = values[j].Item2, Value = values[j].Item1 } });
}
}
}
return data;
}
It most likely has something to do with this code: 它很可能与以下代码有关:
WebRequest request = WebRequest.Create("http://192.168.1.100/st0.xml");
You are making a call to a local IP address and if it's on shared hosting especially, it probably won't like this request. 您正在呼叫本地IP地址,尤其是在共享主机上时,它可能不喜欢此请求。
I already have solved these problem. 我已经解决了这些问题。
After finding a solution I edited code in Web.config by these steps: 找到解决方案后,我通过以下步骤在Web.config中编辑了代码:
<location path="." inheritInChildApplications="false">
<system.web>
...
...
...
</system.web>
</location>
In the next time it could help someone. 下次可以帮助别人。
