无法在Android上使用Web服务
我尝试在android应用程序中使用Web服务。 在.net中创建它的Web服务c＃
我有这个异常“无法处理请求没有一个有效的行动参数，请提供一个有效的肥皂。”。
我不知道这是什么问题，我该怎么做。
请有人可以帮助我！
完成例外：
Code: soap:Sender, Reason: System.Web.Services.Protocols.SoapException: unable to handle request without a valid action parameter. Please supply a valid soap.
à System.Web.Services.Protocols.Soap12ServerProtocolHelper.RouteRequest()
à System.Web.Services.Protocols.SoapServerProtocol.RouteRequest(SoapServerMessage message)
à System.Web.Services.Protocols.SoapServerProtocol.Initialize()

at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:272)
at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:118)
这是我的代码，以消费Web服务：
public class WebserviceCall {
/**
* Variable Decleration................
*
*/
String namespace = "http://10.0.2.2:1378/";
private String url = "http://10.0.2.2:1378/Service1.asmx";
String SOAP_ACTION;
SoapObject request = null, objMessages = null;
SoapSerializationEnvelope envelope;
HttpTransportSE androidHttpTransport;
public WebserviceCall() {
// TODO Auto-generated constructor stub
}
/**
* Set Envelope
*/
protected void SetEnvelope() {
try {
// Creating SOAP envelope
envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
//You can comment that line if your web service is not .NET one.
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
androidHttpTransport = new HttpTransportSE(url);
androidHttpTransport.debug = true;
} catch (Exception e) {
System.out.println("Soap Exception---->>>" + e.toString());
}
}
//Authentification consuming WS
public client GetClientByAuthentification(String email,String password)
{
SOAP_ACTION = namespace + "GetClientByAuthentification";
//Adding values to request object
request = new SoapObject(namespace, "GetClientByAuthentification");
//Adding String value to request object
request.addProperty("eMail", "" + email);
request.addProperty("Password", "" + password);
SetEnvelope();
//SOAP calling webservice
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
//Got Webservice response
String result;
//result = envelope.getResponse().toString();
SoapObject resp=(SoapObject) envelope.getResponse();
result=resp.toString();
Log.e("","result: "+result);
client clt= new client();
clt.setClientFromXmlString(result);
if(!(clt.getNom().isEmpty()))
return clt;
else
return null;
} catch (SoapFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (HttpResponseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
与Web Service应用程序相关的代码：
namespace WebService1
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{
string connectionString = "Data Source=TASSINEMOUHCINE;Initial Catalog=test;Integrated Security=True;Pooling=False";
[WebMethod]
public string GetClientByAuthentification(string eMail, string Password)
{
SqlConnection connexion = new SqlConnection(connectionString);
SqlCommand command = new SqlCommand();
//add Parameters
command.Parameters.Add("@eMail", SqlDbType.VarChar).Value = eMail;
command.Parameters.Add("@Password", SqlDbType.VarChar).Value = Password;
//Execution de la requête 2 permattant de calculer et stocker l'Age
command.Connection = connexion;
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "GetClientByAuthentification";
//
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(command);
da.Fill(ds);
return contextTable(ds, 0, "client");
}
private string contextTable(DataSet ds, int indiceTab, string balisePrincipalName)
{
string context = "";
int i = 0;
foreach (DataRow row in ds.Tables[indiceTab].Rows)
{
context += "<" + balisePrincipalName + " id=""+(i++)+"">";
foreach (DataColumn col in ds.Tables[indiceTab].Columns)
{
context += "<" + col.ColumnName + ">";
context += row[col.ColumnName].ToString();
context += "<" + col.ColumnName + "/>";
}
context += "<" + balisePrincipalName + "/>";
}
return context;
}
}
}
我发现了这个问题。 它工作很棒！
唯一的错误是它在java代码中的命名空间的价值，它应该是
String namespace="http://tempuri.org/";
代替，
String namespace = "http://10.0.2.2:1378/";
