【问题描述】:
我正在尝试从 SOAP 网络服务获取响应,但我遇到了网络异常错误 500。
这是我的班级得到回应:
public static string getResponse()
{
StringBuilder xml = new StringBuilder();
//xml.Append(@"<?xml version=""1.0"" encoding=""utf-8""?>");
xml.Append(@"<soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:br=""http://www.totvs.com.br/br/"" >").Replace(@"\", "");
xml.Append("<soap:Envelope/>");
xml.Append("<soapenv:Body>");
xml.Append("<br:RealizarConsultaSQLAuth>");
xml.Append("<br:codSentenca>GLOBAL_054</br:codSentenca>");
xml.Append("<br:codColigada>0</br:codColigada>");
xml.Append("<br:codAplicacao>V</br:codAplicacao>");
xml.Append("<br:Usuario>xxxx</br:Usuario>");
xml.Append("<br:Senha>xxxx</br:Senha>");
xml.Append("<br:parameters>codcoligada=1;codsistema=V;codusuario=mestre</br:parameters>");
xml.Append("</br:RealizarConsultaSQLAuth>");
xml.Append("</soapenv:Body>");
xml.Append("</soapenv:Envelope>");
string s = getUKMailData(xml.ToString(), "http://xxx.xxxx.com.br:99/xxxx/wsConsultaSQL.asmx");
return s;
}
public static string getUKMailData(string xml, string address)
{
string result = "";
HttpWebRequest request = CreateWebRequest(address);
XmlDocument soapEnvelopeXml = new XmlDocument();
string teste = xml.Replace(@"\", "");
soapEnvelopeXml.LoadXml(teste);
try
{
using (Stream stream = request.GetRequestStream())
{
soapEnvelopeXml.Save(stream);
}
using (WebResponse response = request.GetResponse())
{
using (StreamReader rd = new StreamReader(response.GetResponseStream()))
{
string soapResult = rd.ReadToEnd();
result = soapResult;
}
}
}
catch (WebException wex)
{
var pageContent = new StreamReader(wex.Response.GetResponseStream()).ReadToEnd();
}
return result;
}
public static HttpWebRequest CreateWebRequest(string url)
{
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("SOAP:Action");
webRequest.Headers.Add("username", "xxx");
webRequest.Headers.Add("password", "xxx");
// webRequest.ContentType = "text/xml;charset=\"utf-8\"";
webRequest.Accept = "text/xml";
webRequest.Method = "POST";
webRequest.PreAuthenticate = true;
webRequest.Credentials = CredentialCache.DefaultCredentials;
return webRequest;
}
有人可以帮助我吗?我已经阅读了一系列文章,不幸的是这些文章对我没有帮助。非常感谢!

错误 500 表示服务器以某种方式处理您的请求时遇到错误。设计良好的 API 将通过进一步的代码和响应消息指示发生了什么。例如
500.13是网络服务器正忙。查看响应的内容,它可能包含诸如“'Usuario' 的值无效”之类的消息。我们不太可能仅通过阅读这段(我可能会添加非英语)代码来猜出问题所在。
