我已经开发了一个登录表单（用户名、密码和提交按钮），通过我的 android 应用程序中的soap webservices 使用MySQL 连接。在这里我忘记密码意味着我无法访问我的帐户，那么如何访问我的帐户。因此，当我忘记密码时，意味着单击忘记密码文本视图，然后进入忘记密码活动。在这里，当我输入我的电子邮件 ID 时，意味着我的密码是从 mysql 数据库中检索到的并将其发送到我的电子邮件 ID。
我该怎么办，请指导我。这是我的网络服务代码：
public class Login {
public String authentication(String userName,String password){
String retrievedUserName = "";
String retrievedPassword = "";
String status = "";
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/pro","root","");
PreparedStatement statement = con.prepareStatement("SELECT * FROM customers WHERE login = '"+userName+"'");
ResultSet result = statement.executeQuery();
while(result.next()){
retrievedUserName = result.getString("login");
retrievedPassword = result.getString("password");
}
if(retrievedUserName.equals(userName)&&retrievedPassword.equals(password)){
status = "Success!";
}
else{
status = "Login fail!!!";
}
}
catch(Exception e){
e.printStackTrace();
}
return status;
}
}
这是我的忘记密码 webservice 代码是：
public class ForgetPassword {
public String authentication(String Email){
String retrievedEmail = "";
String status = "";
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/pro","root","");
PreparedStatement statement = con.prepareStatement("SELECT password FROM customers WHERE email = '"+Email+"'");
ResultSet result = statement.executeQuery();
while(result.next()){
retrievedEmail = retrievedEmail + result.getString("password");
retrievedEmail = result.getString("email");
}
if(retrievedEmail.equals(Email)){
status = "Your password has been sent to your email address";
}
else{
status = "No such user exist";
}
}
catch(Exception e){
e.printStackTrace();
}
return retrievedEmail;
}
}
dis 是我忘记密码的安卓代码：
public class ForgetPassword extends Activity {
private final String NAMESPACE = "http://ws.userlogin.com";
private final String URL = "http://192.168.1.168:8085/Login/services/ForgetPassword?wsdl";
private final String SOAP_ACTION = "http://ws.userlogin.com/authentication";
private final String METHOD_NAME = "authentication";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.forget_password);
Button submit = (Button) findViewById(R.id.submit);
submit.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
loginAction();
}
});
}
private void loginAction(){
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
boolean isUserValidated = true;
EditText Email = (EditText) findViewById(R.id.email);
String email = Email.getText().toString();
PropertyInfo unameProp =new PropertyInfo();
unameProp.setName("Email");//Define the variable name in the web service method
unameProp.setValue(email);//set value for userName variable
unameProp.setType(String.class);//Define the type of the variable
request.addProperty(unameProp);//Pass properties to the variable
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
String status = response.toString();
TextView result = (TextView) findViewById(R.id.tv_status);
result.setText(response.toString());
if(status.equals("Success!"))
{
// ADD to save and read next time
String strUserName = Email.getText().toString().trim();
if (null == strUserName || strUserName.length() == 0)
{
// showToast("Enter Your Name");
Email.setError( "Email is required!" );
isUserValidated = false;
}
}
if(isUserValidated)
{
Intent intent = new Intent(ForgetPassword.this,AndroidLoginExampleActivity.class);
startActivity(intent);
}
else
{
Intent i = new Intent(getApplicationContext(), ForgetPassword.class);
startActivity(i);
}
}
catch(Exception e){
}
}
}
请帮助我，如何做到这一点？
