android通过webservice验证用户
在企业应用中，手机与企业数据的交互必不可少，在这里我们通过实例来描述android怎样调用.net webservice
第一步：vs建webservice ,贴出代码:
clsoptuser.cs
public class clsoptuser{
//验证方法
public bool Validate(string u, string p)
{
bool k = false;
SqlConnection userConn = new SqlConnection("连接字符"); userConn.Open();
SqlCommand userComm = new SqlCommand("select *from user", userConn); SqlDataReader userDr = userComm.ExecuteReader();
string tmpuser, tmppass;
while (userDr.Read())
{
int userindex = userDr.GetOrdinal("user");
int passindex = userDr.GetOrdinal("password");
tmpuser = userDr.GetString(userindex);
tmppass = userDr.GetString(passindex);
//用户名和口令正确返回true
if ((tmpuser == u) && (tmppass == p))
{
k = true;
break;
}
}
return k;
}
}
Service.cs
[WebMethod]
public bool ValidateUsername(string username, string pass, string validate)
{
if (validate == "webservice验证码")
{
clsoptuser objoptuser = new clsoptuser();
return objoptuser.Validate(username, pass);
}
else
{
return false;
}
}
以上是服务器端的代码，把上面程序布署到IIS,布署以后可以用IE测试，具体布署我就不说了，网上到处有！
第二步：android客户端
android调用webservice 要用到ksoap2-android-assembly-2.4-jar-with-dependencies.jar一个包，到网上可下载，然后在Eclipce项目中添加处部jar
1、布局文件
main.xml
<?xml version="1.0" encoding="utf-8"?> 想到每次进系统都要输入用户名和密码都恐怖(android的虚拟键盘确实不怎的),所以上面加了个"记住用户名和密码"，方便下次不用输用户名和密码.
2、login.java
login.java
package com.liwei.login;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;
import org.ksoap2.SoapEnvelope;

public class login extends Activity {
Button btnlogin,btnexit; //登录和退出按钮对像

boolean data=false; //调用webservice 近回的数据,验证成功true,失败false HttpThread thread=null; //线程对像
String name=""; //用户名
String pass=""; //口令
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnlogin=(Button)findViewById(R.id.BtnLogin); //获得用户名和密码按钮实例 btnexit=(Button)findViewById(R.id.BtnExit);
edituser=(EditText)findViewById(R.id.EditTextUser); //获得用户名和密码Edittext editpass=(EditText)findViewById(R.id.EditTextPassWord);
//获取上次保存的用户名和密码
SharedPreferences sp=getSharedPreferences("login",Context.MODE_PRIVATE); String tempstr=sp.getString("username", "");
edituser.setText(tempstr);

}catch(Exception ex){
ex.printStackTrace();
}
String url="192.168.3.2:8080/loginweb/service.asmx";//webserivce地址
String nameSpace = "/"; //空间名,可修改

//把用户名传给下一个activity
Bundle bundle = new Bundle(); bundle.putString("KEY_USERNAME",name);
in.putExtras(bundle);
login.this.startActivity(in);
}
else
{
//验证不通过,给出个提示
SharedPreferences sp=getSharedPreferences("login",Context.MODE_PRIVATE); Editor editor=sp.edit();

mit();
new AlertDialog.Builder(prohotel.this) .setTitle(getString(R.string.login_message_title)) .setMessage(getString(R.string.login_message_title)) .setIcon(R.drawable.cancel) .setNeutralButton(getString(R.string.login_button_text), new DialogInterface.OnClickListener() {

}
break;
case 2:

envelope.bodyOut=request;
//

//HttpTransportSE androidHttpTransport = new HttpTransportSE(url); SoapObject result=null;
try{

//得到返回结果
Object temp=envelope.getResult(); response=Boolean.parseBoolean(temp.toString());
}catch(Exception ex){
throw ex;
}
return response;
}
}
}以上验证程序需要访问网络，别忘了在AndroidManifest.xml加入
