如何将参数从Android应用程序传递到asp.net C＃webservice以及如何在asp.net中处理该参数？ [英] how to passing a parameter from android app to asp.net C# webservice and how to handlem that parameter in asp.net?

问题描述

package com.example.dotnwebservice;



import org.ksoap2.SoapEnvelope;

import org.ksoap2.serialization.PropertyInfo;

import org.ksoap2.serialization.SoapObject;

import org.ksoap2.serialization.SoapPrimitive;

import org.ksoap2.serialization.SoapSerializationEnvelope ;

import org.ksoap2.transport.AndroidHttpTransport;





公共类WebserviceCall {



// String namespace =http://www.webserviceX.NET/;

String namespace =http://tempuri.org/ ConvertWeight /;

// private String url =http://www.webservicex.net/ConvertWeight.asmx;

// private String url =http ：//192.168.1.10/Ws/Service1.asmx;

private String url =http://192.168.1.3/vs/Service1.asmx;



String SOAP_ACTION;

SoapObject request = null，objMessages = null;

SoapSerializationEnvelope信封;

AndroidHttpTransport androidHttpTransport;



WebserviceCall（）

{



}





/ **

*设置信封

* /

protected void SetEnvelope（）{



try {



//创建SOAP信封

envelope = new SoapSerializationEnvelope（SoapEnvelope.VER11）;



//如果您的网络服务不是.NET服务，您可以评论该行。

envelope.dotNet = true;



envelope.setOutputSoapObject（request）;

androidHttpTransport = new AndroidHttpTransport（ url）;

androidHttpTransport.debug = true;



} catch（例外e）{

系统。 out.println（Soap Exception ---->>>+ e.toString（））;

}

}



// MethodName变量定义为哪个webservice函数调用

public String ConvertWeight（String MethodName，String weight，

String fromUnit，String toUnit）

{



try {

SOAP_ACTION = namespace + MethodName;



//为请求对象添加值

request = new SoapObject（namespace，MethodName）;



//向请求对象添加Double值

PropertyInfo weightProp = new PropertyInfo（）;

weightProp.setName（Weight）;

weightProp.setValue（weight）;

weightProp.setType（double.class）;

request.addProperty（weightProp）;



//将字符串值添加到请求对象

request.addProperty（ FromUnit，+ fromUnit）;

request.addProperty（ToUnit ，+ toUnit）;



SetEnvelope（）;



试试{



// SOAP调用webservice

androidHttpTransport.call（SOAP_ACTION，信封）;



//得到Webservice响应

字符串结果= envelope.getResponse（）。toString（）;

返回结果;



} catch（例外e）{

// TODO：处理异常

返回e.toString（）;

}

} catch（例外e）{

// TODO：处理异常

返回e.toString（）;

}

}

这是我的用于调用Web服务的android代码





和

。

package com.example.dotnwebservice;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;


public class WebserviceCall {

//String namespace = "http://www.webserviceX.NET/";
String namespace = "http://tempuri.org/ConvertWeight/";
//private String url = "http://www.webservicex.net/ConvertWeight.asmx";
//private String url = "http://192.168.1.10/Ws/Service1.asmx";
private String url = "http://192.168.1.3/vs/Service1.asmx";

String SOAP_ACTION;
SoapObject request = null, objMessages = null;
SoapSerializationEnvelope envelope;
AndroidHttpTransport androidHttpTransport;

WebserviceCall()
{

}


/**
* Set Envelope
*/
protected void SetEnvelope() {

try {

// Creating SOAP envelope
envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

//You can comment that line if your web service is not .NET one.
envelope.dotNet = true;

envelope.setOutputSoapObject(request);
androidHttpTransport = new AndroidHttpTransport(url);
androidHttpTransport.debug = true;

} catch (Exception e) {
System.out.println("Soap Exception---->>>" + e.toString());
}
}

// MethodName variable is define for which webservice function will call
public String ConvertWeight(String MethodName, String weight,
String fromUnit, String toUnit)
{

try {
SOAP_ACTION = namespace + MethodName;

//Adding values to request object
request = new SoapObject(namespace, MethodName);

//Adding Double value to request object
PropertyInfo weightProp =new PropertyInfo();
weightProp.setName("Weight");
weightProp.setValue(weight);
weightProp.setType(double.class);
request.addProperty(weightProp);

//Adding String value to request object
request.addProperty("FromUnit", "" + fromUnit);
request.addProperty("ToUnit", "" + toUnit);

SetEnvelope();

try {

//SOAP calling webservice
androidHttpTransport.call(SOAP_ACTION, envelope);

//Got Webservice response
String result = envelope.getResponse().toString();
return result;

} catch (Exception e) {
// TODO: handle exception
return e.toString();
}
} catch (Exception e) {
// TODO: handle exception
return e.toString();
}
}
/************************************/
}



here is my android code for calling web service


and
.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Script.Services;


namespace AndroidDemoService
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/ConvertWeight")]
    [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
    {

        [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public string ConvertWeight(String MethodName, String weight, String fromUnit, String toUnit)
        {
            if (weight == "" || weight == null)
            {
                string SA = "No Weight Received";
                return SA;
            }
            else
            {
                int W1 = Convert.ToInt32(weight.ToString());
                int weight1 = W1 / 1000;
                string SA = weight1.ToString();
                return weight;
            }
            //string SA = "hey this is test from nikunj.";

        }
    }
}

以上是我的asp.net服务代码我能在Android上获得这个web服务的结果



但是我传递参数从我的应用程序到服务网络服务无法给出结果。



这里在我的网络服务中

只有当其中一部分工作时才会生效当我传递参数

above is my asp.net service code i m able to getting result of this web service in android

but wen i passing parameter from my app to service web service could not giving a result.

here in my webservice
only if part of that is working but else part is not working when i am passing parameters

推荐答案

我发现网络服务名称空间有问题时，部分无法工作





[WebService（Namespace =http://tempuri.org/ConvertWeight）]这个的实例



使用[ WebService（Namespace =http://tempuri.org/ConvertWeight/）]

i find a problem that is in name space in webservice


[WebService(Namespace = "http://tempuri.org/ConvertWeight")] instade of this

use [WebService(Namespace = "http://tempuri.org/ConvertWeight/")]
