Question

我正在创建一个Android应用程序，其中我有一个用户需要填写的表单。然后我想将插入的值发送到一个asp.net页面，该页面捕获数据并将其保存到附加到该页面的数据库中，并在将值插入数据库后，数据库向android应用程序发送响应。像1或0一样作为反馈发送 1表示成功输入数据 0表示失败。

如果可以这样做怎么办？请帮忙，谢谢。

这是你的Android代码

public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/myexample.aspx");

try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("EmpID", "12345"));
 //keep adding like this
nameValuePairs.add(new BasicNameValuePair("SecondVariable", "12345"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = httpResponse.getEntity();
InputStream is = entity.getContent();

//String RESPONSE FROM SERVER
 String whatIgotResponse= convertStreamToString(is);
} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}
}


private static String convertStreamToString(InputStream is) {

    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();

    String line = null;
    try {
        while ((line = reader.readLine()) != null) {
            sb.append((line + "\n"));
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return sb.toString();
}

在ASPX页面中，您可以使用

来检索数据

//all the nameValuePairs your have send
      string EmpID = Request.Form["EmpID"];

//now use your basic SQL Connection with the values to insert
     SQL........

// after the SQL Query you can use 
    Response.Write("Something Something");

将android表单附加到asp.net
