J2ME调用C# WebService的方法(含参数)

经过半个月的努力，终于把了解J2ME调用C# WebService(含参数)的方法，努力了好久，决定和大家分享。在分享之前，要感谢在这个过程中一直帮助我的ωǒs甲骨文和Je m'appelle，是他们的帮助让我掌握了这一方法。

以登陆为例进行分析

登陆代码：

package com.sinic.logic;

import javax.microedition.lcdui.Alert;

import javax.microedition.lcdui.AlertType;

import javax.microedition.lcdui.Command;

import javax.microedition.lcdui.CommandListener;

import javax.microedition.lcdui.Display;

import javax.microedition.lcdui.Displayable;

import javax.microedition.lcdui.Form;

import javax.microedition.lcdui.TextField;

import com.sinic.main.FrmMain;

/**

* <p>Title: UserLogin</p>

* <p>Description: 个性设置：登陆界面</p>

* <p>Company: </p>

* @version 1.0

* */

public class UserLogin extends Form implements CommandListener, Runnable{

private TextField tfUser = new TextField("请编辑手机号码:", "", 11, TextField.NUMERIC);

private TextField tfPass = new TextField("请输入服务密码:", "", 6, TextField.NUMERIC);

private Display display = null;

private FrmMain fm=null;

private Displayable parent = null;

private int result=0;

private Thread t;

private String user=null;

private String pass=null;

private UserMainForm userMain=null;

private final static Command CMD_BACK = new Command("返回", Command.SCREEN, 1);

private final static Command CMD_OK = new Command("确定", Command.SCREEN, 1);

public UserLogin(FrmMain d, Displayable p) {

super("个性设置--用户登陆");

fm = d;

this.parent = p;

append(tfUser);

append(tfPass);

addCommand(CMD_OK);

addCommand(CMD_BACK);

setCommandListener(this);

}

public void commandAction(Command arg0, Displayable arg1) {

String strUser = tfUser.getString().toString();

if (arg0 == CMD_BACK) {

fm.display.setCurrent(parent);

} else if (arg0 == CMD_OK) {

if(strUser.length()!=11){

Alert a = new Alert("个性设置--用户登陆", "手机号码不正确", null, AlertType.INFO);

display.setCurrent(a);

}else{

t=new Thread(this);

t.start();

}

}

}

public void run(){

user = tfUser.getString().toString();

pass = tfPass.getString().toString();

userMain=new UserMainForm(fm,this,user);

result=new J2meToWS().checkUser(user, pass);

if(result==1){

fm.display.setCurrent(userMain);

}else {

Alert a = new Alert("个性设置--用户登陆", "登陆失败", null, AlertType.INFO);

fm.display.setCurrent(a);

System.out.println("~~~~登陆失败~~~~ ");

}

}

}

J2meToWS类：包含checkUser(user, pass)方法

package com.sinic.logic;

import org.ksoap.SoapObject;

import org.ksoap.transport.HttpTransport;

//import org.ksoap2.SoapEnvelope;

//import org.ksoap2.serialization.MarshalBase64;

//import org.ksoap2.serialization.SoapSerializationEnvelope;

/**

* <p>Company: </p>

* @author 朱久长

* @version 1.0

* */

public class J2meToWS {

public J2meToWS() {

}

public int checkUser(String tel,String pwd) {

int result = 0;

try {

SoapObject rpc = new SoapObject("http://tempuri.org/", "Login");

//tel、pwd是方法Login(string tel,string pwd)的两个参数，参数名和个数保持相同

rpc.addProperty("tel", tel);

rpc.addProperty("pwd", pwd);

HttpTransport ht = new HttpTransport("http://localhost/SMSCALLWebService/AppService.asmx",

"http://tempuri.org/Login");

ht.debug=true;

result =Integer.parseInt(ht.call(rpc).toString());

}catch (Exception e) {

e.printStackTrace();

}

return result;

}

}

所调用的WebService文件AppService.asmx含有Login(string tel,string pwd)方法。特别注意，必须加上[SoapRpcService(RoutingStyle = SoapServiceRoutingStyle.SoapAction)]这句声明方了。

using System;

using System.Web;

using System.Collections;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.Data;

using System.Text;

/// <summary>

/// 系统服务

/// </summary>

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

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[SoapRpcService(RoutingStyle = SoapServiceRoutingStyle.SoapAction)]

public class AppService : System.Web.Services.WebService

{

public AppService()

{

//如果使用设计的组件，请取消注释以下行

//InitializeComponent();

}

[WebMethod(Description="系统登录 1：验证通过，2：退订用户，4：密码错误，8：无此用户")]

public int Login(string tel,string pwd)

{

string sql = "SELECT STAT,PWD_NO FROM NO_INFO WHERE NO='" + tel + "'";

DataTable dt = new DataAccess().GetDataTable(sql);

if (dt != null && dt.Rows.Count == 1)

{

string passwordDB = dt.Rows[0]["PWD_NO"].ToString();

if (string.Equals(pwd, passwordDB))

{

int statDB = Convert.ToInt32(dt.Rows[0]["STAT"]);

return statDB == 1 ? 1 : 2;

}

else

{

return 4;

}

}

else

{

return 8;

}

}

}
