Laravel没有从Android应用程序接收发布参数

Question

在读取从android应用发布到laravel方法的数据时遇到麻烦。

我发布的android代码

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(Constants.SAVE_DETAILS_END_POINT);
try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("name1", name1));
        nameValuePairs.add(new BasicNameValuePair("name2", name2));
        ....
        ..
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
     }
catch(...

还有我的Laravel代码，

public function saveDetails(Request $request){
    $modlee = new ModelName();
    $modlee->name1  = $request->get('name1');
    $modlee->name2  = $request->get('name2');;
    ...
    $modlee->save();
    return $modlee;
}

我尝试var_dump($request->get('name1'));为空

总是出现错误，不能插入空值，违反MySQL完整性约束错误，
