HttpWebRequest.GetResponse 给出内部服务器错误

本文关键字：服务器 错误 内部 GetResponse HttpWebRequest | 更新日期: 2023-09-27 18:31:27

我想用Http-Post方法向Web服务发出请求。这是我在 C# 中的代码。

        static void Main(string[] args)
        {
            var _url = "http://localhost/EventWebService/EventWebService.asmx";
            var _action = "http://localhost/EventWebService/EventWebService.asmx?op=GetPerson";
            XmlDocument soapEnvelope = new XmlDocument();
            soapEnvelope.LoadXml(@"<SOAP-ENV:Envelope xmlns:SOAP-ENV=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/1999/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/1999/XMLSchema""><SOAP-ENV:Body><GetPerson xmlns=""http://tempuri.org/"" SOAP-ENV:encodingStyle=""http://schemas.xmlsoap.org/soap/encoding/""><name>Brad</name><surname>Pitt</surname><age>51</age></GetPerson></SOAP-ENV:Body></SOAP-ENV:Envelope>");
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(_url);
            request.Headers.Add("SOAPAction", _action);
            request.ContentType = "text/xml;charset='"utf-8'"";
            request.Accept = "text/xml";
            request.Method = "POST";
            InsertSoapEnvelopeIntoWebRequest(soapEnvelope, request);
            WebResponse response = request.GetResponse();
            StreamReader rd = new StreamReader(response.GetResponseStream());
            Console.WriteLine(rd.ReadToEnd());
        }
        private static void InsertSoapEnvelopeIntoWebRequest(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest)
        {
            using (Stream stream = webRequest.GetRequestStream())
            {
                soapEnvelopeXml.Save(stream);
            }
        }

这是我的 Web 服务方法和使用的类：

    [WebMethod]
    [ return: XmlElement("ReturnValueElement",IsNullable=false)]
    public Person GetPerson([XmlElement("Name")] string name, [XmlElement("Surname")] string surname, [XmlElement("Age")] int age)
    {
        return new Person(name, surname, age);
    }
    public class Person
    {
        string Name { get; set; }
        string Surname { get; set; }
        int Age { get; set; }
        public Person() { }
        public Person(string _name, string _surname, int _age)
        {
            Name = _name;
            Surname = _surname;
            Age = _age;
        }
    };

这是我在 Web 服务配置文件中的配置：

<configuration>
  <system.web>
    <webServices>
        <protocols>
            <add name="HttpSoap"/>              
            <add name="Documentation"/>
            <add name="HttpPostLocalhost"/>
            <add name="HttpPost"/>
        </protocols>
    </webServices>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
  </system.web>
</configuration>

在 Main 中，当我调试WebResponse response = request.GetResponse();行时，我收到具有协议错误状态的内部服务器错误 （500）。

有什么想法吗？谢谢大家。

HttpWebRequest.GetResponse 给出内部服务器错误

将此代码与 Try and Catch 方法一起使用

try
{
  // Your Code 
}
catch(Exception wex)
{
  string pageContent = new StreamReader(wex.Response.GetResponseStream()).ReadToEnd().ToString();
  return pageContent;
}
