Android无法连接网络服务器

Question

我使用“ xampp”构建Web服务器，并在C：\\ xampp \\ htdocs上创建“ abc.php”。

完成所有工作后，我链接“ localhost / abc.php”。

使用Pc google欺骗URL可以显示“这是服务器的消息”。

到目前为止一切都很好。直到我想用android连接网络服务器。

我尝试了很多方法（包括关闭防火墙或防病毒等），但仍然失败。

我已经尝试谷歌（Android手机）连接“ http：//MyIP/abc.php ”，而不是通过此程序。

结果是可以在Google（Android手机）中显示我的“ abc.php”。

但我不知道哪里出错。 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。 无法从Internet上访问它，因此具有蜂窝连接的Android手机无法连接到它。 您需要在公共托管服务上而不是在本地计算机上运行Web应用程序。
