問題描述

我正在嘗試使用hyperlink將數據發送到PHP Server，並希望將發送的數據顯示到同一hyperlink 。

在運行應用程序並單擊按鈕后，我得到了一個帶有響應的Toast ： received: received: Array

我的MainActivity.Java ： 

package com.vtgames.intuitionsoftwares.jsonwebservice;

import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;

import javax.net.ssl.HttpsURLConnection;


public class MainActivity extends Activity {

    Button bt;
    TextView txt;




    // Response
    String responseServer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        txt = (TextView) findViewById(R.id.raw);
        bt = (Button) findViewById(R.id.sendData);
        bt.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
            new SendPostRequest().execute();
            }

    }


    public class SendPostRequest extends AsyncTask<String, Void, String> {

        protected void onPreExecute(){}

        protected String doInBackground(String... arg0) {

            try {

                URL url = new URL("https://******.com/name2.php"); // here is your URL path

                JSONObject postDataParams = new JSONObject();
                postDataParams.put("name", "MyName");
                postDataParams.put("email", "myname@gmail.com");
                Log.e("params",postDataParams.toString());

                HttpURLConnection conn = (HttpURLConnection) url.openConnection();

                conn.setRequestMethod("POST");
                conn.setDoInput(true);
                conn.setDoOutput(true);

                OutputStream os = conn.getOutputStream();
                BufferedWriter writer = new BufferedWriter(
                        new OutputStreamWriter(os, "UTF-8"));
                writer.write(getPostDataString(postDataParams));

                writer.flush();
                writer.close();
                os.close();

                int responseCode=conn.getResponseCode();

                if (responseCode == HttpsURLConnection.HTTP_OK) {

                    BufferedReader in=new BufferedReader(new
                            InputStreamReader(
                            conn.getInputStream()));

                    StringBuffer sb = new StringBuffer("");
                    String line="";

                    while((line = in.readLine()) != null) {

                        sb.append(line);
                        break;
                    }

                    in.close();
                    return sb.toString();

                }
                else {
                    return new String("false : "+responseCode);
                }
            }
            catch(Exception e){
                return new String("Exception: " + e.getMessage());
            }

        }

        @Override
        protected void onPostExecute(String result) {
            Toast.makeText(getApplicationContext(), result,
                    Toast.LENGTH_LONG).show();
        }
    }

    public String getPostDataString(JSONObject params) throws Exception {

        StringBuilder result = new StringBuilder();
        boolean first = true;

        Iterator<String> itr = params.keys();

        while(itr.hasNext()){

            String key= itr.next();
            Object value = params.get(key);

            if (first)
                first = false;
            else
                result.append("&");

            result.append(URLEncoder.encode(key, "UTF-8"));
            result.append("=");
            result.append(URLEncoder.encode(value.toString(), "UTF-8"));

        }
        return result.toString();
    }

}

和我的Server PHP Code **name2.php** 。 

<?php
header("Pragma: no-cache");
header("Cache-Control: no-cache");
header("Expires: 0");
$Data_array_received = array();
$Data_array_received = $_POST;
$Data_received_from_array= $Data_array_received["params"];
echo "received:  ".$Data_received_from_array;
echo "received:  ".$Data_array_received;
print_r($_POST);

?>

現在，一旦我打開鏈接，我將看到：“ received：received：Array”在Toast我在顯示Response的地方再次看到：“ received：received：Array”

但是我想在鏈接以及響應中顯示{"email":"abc@gmail.com","name":"abc"} 。

因此，請在我做錯地方幫助我。

您應該使用類似翻新的庫： http : //square.github.io/retrofit/或Fast-Android-Networking： https : //github.com/amitshekhariitbhu/Fast-Android-Networking或android-async-http： http： //loopj.com/android-async-http/

要發布，將數據獲取到服務器並進行調試。
