Android应用程序无法将详细信息发布到url

我有一个Android应用程序，可以发布到"http://jont.byethost3.com/gcmtest/gcm.php?shareRegId=true".访问后，应用程序会向脚本发布一个id密钥，php文件会将其保存到我的文件服务器上的文本文件中。我已经在浏览器中手动输入了url，由于没有收到任何POST数据，它成功地生成了一个空文本文件，但当我在应用程序上测试它时，它不起作用。

我使用Asynchttp来调用和传递像这样的数据

private void backgroundRegister(final String username){
    new AsyncTask<Void, Void, String>(){
        @Override
        protected String doInBackground(Void... params) {
            String msg = "";
            try{
                if(gcmObj==null){
                    gcmObj = GoogleCloudMessaging.getInstance(getApplicationContext());
                }
                registerID = gcmObj.register(AppConstants.PROJ_ID);
                msg = "Registration ID : " + registerID;
                Log.d("REGOID",registerID);
            }catch(IOException e){
                Log.d("IOEXCEPTION",e.toString());
            }
            return msg;
        }
        @Override
        protected void onPostExecute(String s) {
            if(!TextUtils.isEmpty(registerID)){
                savetoSharedPrefs(getApplicationContext(),registerID,username);
                Toast.makeText(getApplicationContext(),"Registered with GCM",Toast.LENGTH_LONG).show();
            }else{
                Toast.makeText(getApplicationContext(),"Registration failed",Toast.LENGTH_LONG).show();
            }
        }
    }.execute(null, null, null);
}
private void savetoSharedPrefs(Context context, String registerID,String userName){
    SharedPreferences prefs = getSharedPreferences("userDetails", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = prefs.edit();
    editor.putString(regID, registerID);
    editor.putString(userNAME, userName);
    editor.commit();
    storeREG();
}
//store in the file server (PHP)
private void storeREG(){
    pg.show();
    params.put("regID", registerID);
    //Make RESTful webservice call
    AsyncHttpClient client = new AsyncHttpClient();
    client.post(AppConstants.SERVER_URL,params,new AsyncHttpResponseHandler(){
        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
            pg.hide();
            if(pg!=null){
                pg.dismiss();
            }
            Toast.makeText(getApplicationContext(),"ID sharing successful",Toast.LENGTH_LONG).show();
            Intent home = new Intent(getApplicationContext(),HomeActivity.class);
            home.putExtra("regID",registerID);
            Log.d("REGID",registerID);
            startActivity(home);
            finish();
        }
        @Override
        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
            pg.hide();
            if(pg!=null){
                pg.dismiss();
            }
            if(statusCode==404){
                Toast.makeText(getApplicationContext(),"Requested resource not found",Toast.LENGTH_LONG).show();
            }else if(statusCode==500){
                Toast.makeText(getApplicationContext(),"Something went wrong at the server",Toast.LENGTH_LONG).show();
            }else{
                Toast.makeText(getApplicationContext(),"Unexpected error occurred",Toast.LENGTH_LONG).show();
            }
        }

    });
}

我想传递的数据只是纯文本。我希望有人能帮我。

编辑

我的php脚本

if(!empty($_GET["shareRegId"])) {
    $gcmRegID  = $_POST["regID"]; 
    //echo $gcmRegID;
    file_put_contents("./GCMRegId.txt",$gcmRegID);
    echo "Done!";
    exit;
    }

我的舱单以防万一

更新：我已经设法使用我的mamp服务器在本地运行了这个代码，当我上传到这个主机时，问题仍然存在。
