java - 如何使用异步http post将数据从android studio发送到xampp并在真实设备中运行？

Question

我在异步 http post 上遇到问题，如果使用模拟器运行，我已经设法将数据从 EditText 发送到服务器。但在使用真实设备时失败。如果使用 tge 真实设备运行，如何能够将数据从 android studio 发送到服务器(xampp)？

import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ProgressBar;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private EditText value;
    private Button btn;
    private ProgressBar pb;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        value = (EditText)findViewById(R.id.editText1);
        btn = (Button)findViewById(R.id.button1);
        pb = (ProgressBar)findViewById(R.id.progressBar1);
        pb.setVisibility(View.GONE);
        btn.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (value.getText().toString().length()<1){
            Toast.makeText(getApplicationContext(),"Isi sesuatu Dong!",Toast.LENGTH_LONG).show();
        }else{
            pb.setVisibility(View.VISIBLE);

        }
    }

    private class MyAsyncTask extends AsyncTask<String,Integer,Double>{

        @Override
        protected Double doInBackground(String... params) {
           postData(params[0]);
            return null;
        }


        protected void onPostExecute(Double hasil) {
            pb.setVisibility(View.GONE);
            Toast.makeText(getApplicationContext(),"Berhasil dikirim",Toast.LENGTH_LONG).show();
        }

        protected void onProgressUpdate(Integer... progress) {
            pb.setProgress(progress[0]);
        }

        public void postData(String nilaiYangDikirim){
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost("http://10.0.2.2/http/index.php");

            try {
                List<NameValuePair>  nilai = new ArrayList<NameValuePair>();
                nilai.add(new BasicNameValuePair("myHttpData", nilaiYangDikirim));
                httpPost.setEntity(new UrlEncodedFormEntity(nilai));
                HttpResponse response = httpClient.execute(httpPost);

            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
            } catch (IOException e) {
                // TODO Auto-generated catch block
            }
        }
    }
}

Answer 1

如果您要使用真实设备测试代码，则必须记下系统的 IP 地址。

转到 CMD->输入 ipconfig/all(windows) 并在 ubuntu 中输入 ip [选项]

然后记下无线局域网适配器的 IP 地址(可能以 192.168.* .* 开头)

然后转到 xampp 文件夹并搜索 httpd-xampp.conf

输入来自 192.168 的允许。 *。 * 在文件末尾

在系统中创建Adhoc网络或wifi P2P网络

连接到手机中的P2p网络

最后将代码改成这样

 HttpPost httpPost = new HttpPost("http://192.168.*.*/http/index.php");
