Question

我刚接触Android开发。目前，我在android客户端做注册功能。我现在要做的只是将用户名和密码传递到JSP页面。但是当我尝试使用我的应用时，似乎没有将值传递给JSP。

机器人：

    public class RegisterActivity extends Activity {
    String url = "http://101.78.175.101:20281/test/useradd.jsp";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        try {
            setContentView(R.layout.registeractivity);
            HttpClient client = new DefaultHttpClient();
            HttpPost post = new HttpPost(url);

            List<NameValuePair> pairs = new ArrayList<NameValuePair>();
            pairs.add(new BasicNameValuePair("uid", "hardik"));
            pairs.add(new BasicNameValuePair("pwd", "trivedi"));
            post.setEntity(new UrlEncodedFormEntity(pairs));
            client.execute(post);

            TextView mail = (TextView) findViewById(R.id.Register_mail);
            mail.setText("hello");

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

JSP代码：

<%@ page import="java.sql.*" %>

<%
String connectionURL = "jdbc:mysql://localhost:3306/xxx";
Connection connection = null;
Statement statement = null;
int insert_flag = 0 ;
%>

<html>
<body>
<% 
   String insert_sql ;
   String usermail, password; 
   usermail=request.getParameter("uid");  
   password=request.getParameter("pwd");  

Class.forName("com.mysql.jdbc.Driver").newInstance();
connection = DriverManager.getConnection(connectionURL, "xxx", "xxx");
statement = connection.createStatement();

insert_sql = "insert into user ( usermail, userpassword ) values ( '" + usermail + "' , '" + password + "')" ; 
insert_flag = statement.executeUpdate( insert_sql );

if ( insert_flag > 0 ) out.println("record inserted") ;

%>
</body>
</html>

您可以使用您的请求传递查询参数。在JSP中，您可以通过以下方式检索值：

<%= request.getParameter("name") %>
