Question

我想从我的Android应用程序发送数据到servlet。我试图在我的应用程序中使用它：

    private boolean postData(String s) {
    HttpClient httpclient = new DefaultHttpClient();

    HttpPost httppost = new HttpPost(s); // s is my url

    try {

        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("id", "1003"));
        nameValuePairs.add(new BasicNameValuePair("name", "Anil"));
        nameValuePairs.add(new BasicNameValuePair("loc", "Kalyan"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
    }  catch (Exception e) {
        // TODO Auto-generated catch block
        return false;
    }
    return true;
}

我是这种方法，但无法导入这些文件：

    import org.apache.http.client.methods.HttpPost;
    import org.apache.http.impl.client.DefaultHttpClient;
    import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;

如何在android studio中影响这些文件？或者还有其他方法吗？ Thanx提前

Android 6.0版本删除了对Apache HTTP客户端的支持。如果您的应用使用此客户端并定位到Android 2.3（API级别9）或更高版本，请改用HttpURLConnection类

 URL url = new URL(path);
 HttpURLConnection conn = (HttpURLConnection) url.openConnection();
 conn.setRequestMethod("POST");
 conn.setConnectTimeout(10000);
 conn.setReadTimeout(2000);
 conn.setDoOutput(true);
 byte[] bypes = params.toString().getBytes();
 conn.getOutputStream().write(bypes);
 InputStream inStream = conn.getInputStream();

如何从android studio中的android应用程序向servlet发送数据？
