Java 从Android调用Web服务时获取异常

我是这方面的初学者，在从android调用asp.NETWeb服务方法（注册）时遇到了一个问题。当我在浏览器上尝试时，它工作得很好，但当我在android上尝试时，它会给我一些例外，比如 "

SoapFault-faultcode:'soap:Client'faultstring:'System.Web.Services.Protocols.SoapException:服务器未识别HTTP标头SOAPAction:SignUp的值。 在System.Web.Services.Protocols.Soap11ServerProtocolHelper.RouterRequest（）中 在System.Web.Services.Protocols.SoapServerProtocol.Initialize（）中 位于System.Web.Services.Protocols.ServerProtocol.SetContext（类型类型、HttpContext上下文、HttpRequest请求、HttpResponse响应） 在System.Web.Services.protocol.ServerProtocolFactory.Create（类型、HttpContext上下文、HttpRequest请求、HttpResponse响应、Boolean&abortProcessing）中的faultactor:'null'详细信息：org.kxml2.kdom

这是我的Java注册类

String SOAP_ACTION1 = "http://tempuri.org/SignUp";
String METHOD_NAME1 = "SignUp";
btn = (Button)findViewById(R.id.btn_signup);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new WebService().execute(METHOD_NAME1,SOAP_ACTION1,txt_name.getText().toString(),                  txt_email.getText().toString(),txt_password.getText().toString(),
                    txt_address.getText().toString(),
                    txt_dob.getText().toString(),
                    txt_account.getText().toString(),                       
                 txt_cnic.getText().toString(),txt_pobox.getText().toString(),                       
               txt_city.getText().toString(),txt_status.getText().toString());

这是我的JavaWebService类

 private static String NAMESPACE = "http://tempuri.org/";
private static String URL = "http://192.168.0.102/MyWebService/WebService1.asmx?WSDL";
 protected String doInBackground(String... params) {
    String s="";
    String whichmethodcall = params[0];
    switch(whichmethodcall){
        case "SignUp":
            s = signup(params);
            break;
        case "SignIn":
            s = signin(params);
            break;
    }
    return s;
}
 public String signup(String[] arr){
    String s = "";
    SoapObject request = new SoapObject(NAMESPACE, arr[1]);
    //Use this to add parameters
    request.addProperty("cname",arr[2]);
    request.addProperty("cemail",arr[3]);
    request.addProperty("cpwd",arr[4]);
    request.addProperty("caddress",arr[5]);
    request.addProperty("cdob",arr[6]);
    request.addProperty("caccount",arr[7]);
    request.addProperty("cCnic",arr[8]);
    request.addProperty("cpobox",arr[9]);
    request.addProperty("cCity",arr[10]);
    request.addProperty("cstatus",arr[11]);

    //Declare the version of the SOAP request
    SoapSerializationEnvelope envelope = new 
    SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(request);
    envelope.dotNet = true;

    try {
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        //this is the actual part that will call the webservice
        androidHttpTransport.call(arr[0], envelope);

        // Get the SoapResult from the envelope body.
       // SoapObject result = (SoapObject)envelope.bodyIn;
       // SoapObject result = (SoapObject) envelope.getResponse();
        if (envelope.bodyIn instanceof SoapFault) {
            final SoapFault result = (SoapFault) envelope.bodyIn;
            if (result != null) {
                //Get the first property and change the label text
                   s = result.toString();
            } else
                s = "No response";              
        }
    } catch (Exception e) {
        e.printStackTrace();
        s=e.getMessage().toString();
    }
    return s;
}

这是我的asp.NETWebService方法

 public string SignUp(string cname, string caddress, string cdob, long caccount, long cCnic, int cpobox, string cCity, string cstatus,string cemail, string cpass)
    {
        bool check = ConnectDB();           // Opens the Connection to Insert The new User
        string msg = "";
        //DateTime dob = DateTime.ParseExact(cdob, "dd/mm/yyyy", null);
        string query = "INSERT INTO Customers values('" + cname + "','" + caddress + "','" + cdob + "','" + caccount + "','" + cCnic + "','" + cpobox + "','" + cCity + "','" + cstatus + "','"+ cemail + "','"+ cpass + "')";
        SqlCommand comm = new SqlCommand(query, con);
        try{
            if (check == true){
                if (comm.ExecuteNonQuery() > 0)
                    msg = "you've signed up !";
                else
                    msg = "sign up error";                   
            }
            else               
                msg = "Database not Connected";               
        }catch (SqlException ex){
            msg = ex.Message.ToString();
            con.Close();
        }finally{
            con.Close();
        }
        return msg;
    }

你能试试这个吗

而不是SoapObject请求=新的SoapObject（名称空间，arr[1]）； 使用

SoapObject请求=新的SoapObject（命名空间，arr[0]）

在soap对象中，应该只传递方法名，而不传递http://...

看起来您正在使用ksoap2。传输有两个字段requestDump和responseDump，这对调试非常有用。您能在最后一个子句（transport.requestDump！=null）{Log.d（getClass（）.getName（），methodId+“”+transport.requestDump）；}中添加类似的内容吗{Log.d（getClass（）.getName（），“+methodId”无请求转储）；}如果（transport.responseDump！=null）{Log.d（getClass（）.getName（），methodId+“”+transport.responseDump）；}else{Log.d（getClass（）.getName（），“+methodId”无响应转储）；}arr[2]包含custname。我应该在其中传递方法名。否？是的，刚刚看到..没有任何更改，我仍然得到相同的异常查看我在原始消息下的注释。尝试打印requestDump和ResponseDump忘记提及您必须添加androidHttpTransport.debug=true创建传输后另一个问题我看到参数不匹配您d“cpwd”，但服务器需要“cpass”
