Android 无法连接网络服务器

Question

我使用 "xampp" 构建了一个网络服务器，并在 C:\xampp\htdocs.

上创建了 "abc.php"

完成所有工作后，我link "localhost/abc.php"。

使用Pcgoogle欺骗URL可以显示"This is server's message".

到目前为止 good.Until 我想 android 连接网络服务器。

我尝试了很多方法（包括关闭防火墙或杀毒软件等），但仍然失败。

我已经尝试 google(android phone) 连接“http://MyIP/abc.php”，而不是通过这个程序。

结果是可以在google(android phone).

中显示我的"abc.php"

但不知道哪里出错了。我无法使用我的程序获取 URL

package com.testdb;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {

    private TextView textView;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = (TextView)findViewById(R.id.textView1);
        db message = new db();
        String msg = message.stringQuery("http://10.0.2.2/abc.php");
        textView.setText("Server message is "+msg);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

package com.testdb;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;

public class db {

    public String stringQuery(String url){
        try
        {
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost method = new HttpPost(url);
            HttpResponse response = httpclient.execute(method);
            HttpEntity entity = response.getEntity();
            if(entity != null){
                return EntityUtils.toString(entity);
            }
            else{
                return "No string.";
            }
         }
         catch(Exception e){
             return "Network problem";
         }
    }
}

这是我的日志

Answer 1

10.0.2.2 是您本地网络上的 IP 地址。它无法从 Internet 访问，因此使用蜂窝网络连接的 Android phone 无法连接到它。您需要运行您的 Web 应用程序在 public 托管服务上，而不是在您的本地计算机上。
