用需要的c#帮助发送SOAP消息
本文关键字:SOAP 消息 帮助 | 更新日期: 2023-09-27 18:14:35
我想向Web服务发送一个SOAP消息并读取响应。我的代码如下:感谢您的帮助。
我希望我的问题不要重复,我已经四处寻找解决方案,但我没有成功。

sendSoapMessage();
}

{
XmlDocument doc = new XmlDocument();
doc.InnerXml = @"<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://coreg.surveycenter.com/RegistrationGateway/PanelistService.asmx");
//if (proxy != null) req.Proxy = new WebProxy(proxy, true);
// req.Headers.Add("GetClientInfo", "http://tempuri.org/GetClientInfo");
req.ContentType = "text/xml;charset='"utf-8'"";
req.Accept = "text/xml";
req.Method = "POST";
Stream stm = req.GetRequestStream();
doc.Save(stm);
stm.Close();
WebResponse resp = req.GetResponse();
stm = resp.GetResponseStream();
StreamReader r = new StreamReader(stm);
Response.Write(r.ReadToEnd());
//Response.Write(stm.ToString());
//Response.Write(r.ToString());
Response.End();
}
}
}
更新正如Darin建议的那样。我按照指示做了,但是下面的代码行
using (var client = new RegistrationBindingsClient("RegistrationBindings"))
给出错误
The type or namespace name 'RegistrationBindingsClient' could not be found (are you missing a using directive or an assembly reference?)
如有任何帮助,不胜感激
您尝试使用的web服务在以下地址提供WSDL。因此,只需右键单击解决方案资源管理器中的引用,并使用Visual Studio中的添加服务引用对话框并指向WSDL,它将为您生成强类型类,以便轻松地使用服务,就像这样:
protected void sendSoapMessage()
{
using (var client = new RegistrationBindingsClient("RegistrationBindings"))
{
var registration = new RegistrationType();
registration.Source = new SourceType();
registration.Source.SourceID = "50001255";
registration.Email = "adsvine@gmail.com";
registration.FirstName = "Muz";
registration.LastName = "Khan";
var countryUK = new CountryTypeUK();
countryUK.CountryID = 2000077;
countryUK.Language = 2000240;
countryUK.Address = new AddressTypeUK();
countryUK.Address.Postalcode = "N19 3NU";
registration.Item = countryUK;
registration.DOB = new DateTime(1977, 3, 8);
registration.Gender = 2000247;
client.SubmitPanelist(registration);
}
}
看这有多容易。您不应该担心任何SOAP和XML管道。
如果您对使用以下请求在网络上发送的实际底层SOAP信封感兴趣:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SubmitPanelist xmlns="http://www.greenfield.com/RegistrationGateway/Messages">
<Registration xmlns="http://www.greenfield.com/RegistrationGateway/Types">
<Source>
<SourceID>50001255</SourceID>
</Source>
<Email>adsvine@gmail.com</Email>
<FirstName>Muz</FirstName>
<LastName>Khan</LastName>
<CountryUK>
<CountryID>2000077</CountryID>
<Language>2000240</Language>
<Income>0</Income>
<Education>0</Education>
<Address>
<Postalcode>N19 3NU</Postalcode>
</Address>
</CountryUK>
<DOB>1977-03-08</DOB>
<Gender>2000247</Gender>
</Registration>
</SubmitPanelist>
</s:Body>
</s:Envelope>
是否有任何错误消息或您使用了HTTP监视器?

- XmlDocument保存方法 如何使用WebRequest类发送数据类似的问题在stackoverflow可能有帮助
您可以通过两种方法访问该服务:
-
通过添加服务的web引用。在visual studio中,你可以右键单击你的项目,选择Add Web reference选项,然后粘贴服务的URL。
-
在Visual studio命令提示符中使用wsdl工具从wsdl生成客户端代理。命令如下:
c:>
它将生成一个.cs文件和一个output.config。在项目中包含.cs文件,您可以直接使用它来访问服务。确保配置文件条目被添加到您的项目配置中。
如果你想使用HttpWebRequest,然后找到下面的代码:
string soap =
@"<?xml version=""1.0"" encoding=""utf-8""?>
<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance""
xmlns:xsd=""http://www.w3.org/2001/XMLSchema""
xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
<soap:Body>
<Register xmlns=""http://tempuri.org/"">
<id>123</id>
<data1>string</data1>
</Register>
</soap:Body>
</soap:Envelope>";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost/WebServices/CustomerWebService.asmx");
req.Headers.Add("SOAPAction", "'"http://tempuri.org/Register'"");
req.ContentType = "text/xml;charset='"utf-8'"";
req.Accept = "text/xml";
req.Method = "POST";
using (Stream stm = req.GetRequestStream())
{
using (StreamWriter stmw = new StreamWriter(stm))
{
stmw.Write(soap);
}
}
WebResponse response = req.GetResponse();
Stream responseStream = response.GetResponseStream();
// TODO: Do whatever you need with the response
My Service看起来像:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class CustomerWebService : System.Web.Services.WebService
{
[WebMethod]
public string Register(long id, string data1)
{
return "ID.CUSTOMER";
}
}
这是一个通用类,你可以使用它来实现你需要的。
重要免责声明:您应该仅在希望(或需要)手动发出基于soap的web服务时使用此声明:在大多数常见场景中,您应该将web服务WSDL与Add service Reference Visual Studio特性一起使用,这是正确的方法。
