Android - 从资产执行 php 脚本

Question

我需要在我的应用程序中使用带有文本输出的 PHP 脚本。 我有以下代码：

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import java.io.ByteArrayOutputStream;
import java.io.IOException;

import org.apache.http.*;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;


public class Fourth_Fragment extends Fragment {
    View myView4;
    //TextView textl;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        myView4 = inflater.inflate(R.layout.fourth_layout, container, false);

        //textl = (TextView)myView4.findViewById(R.id.LoungeTest);
        //textl.setText(outputlog);
        final String url = "file:///android_asset/lounge.php";
        new Thread() {
            @Override
            public void run() {
                try {
                    HttpClient httpclient = new DefaultHttpClient();
                    HttpResponse response = httpclient.execute(new HttpGet(url));
                    StatusLine statusLine = response.getStatusLine();
                    if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
                        ByteArrayOutputStream out = new ByteArrayOutputStream();
                        try {
                            response.getEntity().writeTo(out);
                            out.close();
                        } catch (IOException e) {
                        }
                        String responseString = out.toString();
                        //..more logic
                    } else {
                        //Closes the connection.
                        try {
                            response.getEntity().getContent().close();
                            throw new IOException(statusLine.getReasonPhrase());
                        } catch (IOException e) {
                        }
                    }
                }
                catch (ClientProtocolException e)
                {

                }
                catch (IOException e)
                {

                }
            }
        }.start();

        return myView4;
    }




}

这是 logcat：

那么有什么办法，如何在带有文本输出（作为字符串）的 Android java App 中执行 PHP 脚本（位于 assets 文件夹中）？谢谢

Answer 1

如何在带有文本输出（作为字符串）的 Android java App 中执行 PHP 脚本（位于 assets 文件夹中的文件）？

不是真的。 Android 没有内置 PHP 解释器。 PHP是Web服务器常用的一种技术； Android 也没有内置 Web 服务器。

欢迎您尝试寻找适用于 Android 的 PHP 解释器，然后尝试弄清楚如何使用它来执行您的 PHP 脚本。最有可能的是，首先摆脱 PHP 脚本会为您提供更好的服务。

Answer 2

首先，我认为你的网址是错误的，

final String url = "file:///android_asset/lounge.php";

应该是这样的

final String url = "http://127.0.0.1/android_asset/lounge.php"; 

其中 127.0.0.1 是用于 localhost 的 ip。

用于本地系统。
