Question

我的项目包含一个电话Network.SendLocation();和以下类：

package com.example.getcurrentlocation;

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

import android.os.Build;
import android.os.StrictMode;
import android.os.StrictMode.ThreadPolicy;
import android.util.Log;

public class Networking{

    public void SendLocation(){
        if (Build.VERSION.SDK_INT>= 10) {
            ThreadPolicy tp = ThreadPolicy.LAX;
            StrictMode.setThreadPolicy(tp);
            }
        //Create a new HttpClient and Post Header
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost("http://localhost:8080/BW/Test.php");

            try {
                // Add your data
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                nameValuePairs.add(new BasicNameValuePair("id", "12345"));
                nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                // Execute HTTP Post Request
                HttpResponse response = httpclient.execute(httppost);
                // writing response to log
                Log.d("Http Response:", response.toString());
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
            } catch (IOException e) {
                // TODO Auto-generated catch block
            }
     }
}

出于某种原因，我无法从通话中获得任何数据（同样适用于呼叫＆＃34; http://www.google.com＆＃34;）。同样，php从不执行任何操作，所以它根本就没有命中它。我无法弄清楚它为什么不起作用的原因。在整个电话会议之前和之后，我都用烤面包进行了测试。

Answer 1

在Android中您需要连接本地服务器意味着您需要使用“http://10.0.2.2”或“http://YOUR SERVER IP”而不是“http://localhost:8080”

Answer 2

您的代码看起来正确，这是我的工作代码。

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_8));

HttpResponse response = client.execute(httppost);
HttpEntity httpEntity = response.getEntity();
String state = EntityUtils.toString(httpEntity);
Log.i("henry", "state = "+state);

并确保你的php必须回应一些东西

<?PHP
    echo $_POST['id'];
?>

没有收到邮件请求的数据
