Question

我正在尝试将一些数据解析为php中的表单。但是下面的内容正在发生此代码中是否有任何错误，因为这会在log cat中打印webview的php echo，但这些值未在webview中显示。

 x=getIntent().getStringExtra("name");
            tot=getIntent().getStringExtra("total");
            fuel=getIntent().getStringExtra("fuel");
            phone=getIntent().getStringExtra("phone");
            mail=getIntent().getStringExtra("driver_email");

            Log.e("name", x);

            try {
                postData();
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }



        }
        public void postData() throws JSONException{
             StrictMode.ThreadPolicy policy = 
                        new StrictMode.ThreadPolicy.Builder().permitAll().build();      
                            StrictMode.setThreadPolicy(policy);
            // Create a new HttpClient and Post Header
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(payUrl);
            JSONObject json = new JSONObject();

            try {
                // JSON data:
                json.put("name", x);
                json.put("total", tot);
                json.put("fuel", fuel);
                json.put("phone", phone);
                json.put("mail", mail);


                JSONArray postjson=new JSONArray();
                postjson.put(json);

                // Post the data:
                httppost.setHeader("json",json.toString());
                httppost.getParams().setParameter("jsonpost",postjson);

                // Execute HTTP Post Request
                System.out.print(json);
                HttpResponse response = httpclient.execute(httppost);

                // for JSON:
                if(response != null)
                {
                    InputStream is = response.getEntity().getContent();

                    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
                    StringBuilder sb = new StringBuilder();

                    String line = null;
                    try {
                        while ((line = reader.readLine()) != null) {
                            sb.append(line + "\n");
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    } finally {
                        try {
                            is.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }

                    y = sb.toString();
                    Log.e("y",y);
                }

接收数据的php代码是

 $data = json_decode($json);
    echo "Array: \n";
    echo "--------------\n";
    var_dump($data,true);
    echo "\n\n";

    $name= $data->name;
     $mail= $data->mail;
      $phone= $data->phone;
       $fuel= $data->fuel;
        $total= $data->total;
    $pos = $data->position;

    echo $data->name;
    echo "Result: \n";
    echo "--------------\n";
    echo "Name     : ".$name."\n Position : ".$pos."\n mail: ".$mail."\n phone : ".$phone."\n fuel : ".$pos."\ total : ".$pos;

但是，当我试图回声值不弹出。任何帮助我正在添加我的logcat和echo以获得更好的underxsxtanding

 JSON: -------------- NULL Array: -------------- NULL Result: -------------- Name : Position : mail: phone : fuel : \ total :
