JSON例外的Andr​​oid [英] JSON exception in Android

问题描述

我想在本地主机上的数据库中执行的查询和发送JSON对象到客户端Android版。我不是能知道什么是我的code中的问题。所以，有人请帮助我在这方面。

I am trying to execute query on database in the localhost and send the JSON object to the client in android. I m not been able to know what is the problem in my code. So some one please help me on this regard.

我的PHP code是一个在那里I M发送JSON对象。
的 PHP code 的

My php code is the one where i m sending the JSON object. php code

查询执行成功。

$row=mysql_fetch_array($result1);


    $email=$row['EM'];
    $pass=$row['PASS'];

    $post=array("email"=>$email, "pass"=>$pass); 
    $posts[] = array("post"=>$post);
    //echo "SUCCESS";
    header('Content-type: application/json');

    echo json_encode(array("posts"=>$posts));

和android的身边，我已经这样code以下;

And in android side i ve this code below;

HttpResponse response = doPost(url, kvPairs);
        String responseBody=response.toString();
        String temp = EntityUtils.toString(response.getEntity());
        if (temp.compareTo("SUCCESS")==0)
        {
            Toast.makeText(this, "Working", Toast.LENGTH_LONG).show();
        }

以上部分执行..
低于code抛出一个异常的JSON

Above part executes .. Below code throws a JSON exception

        JSONObject json = new JSONObject(responseBody);
    JSONArray jArray = json.getJSONArray("posts");
    no_of_obj=jArray.length();
    nemail=new String[no_of_obj];
    npass=new String[no_of_obj];
    for (int i = 0; i < jArray.length(); i++) {
        JSONObject e = jArray.getJSONObject(i);
        String s = e.getString("post");
        JSONObject jObject = new JSONObject(s);
       Toast.makeText(context,jObject.getString("email")+":"+jObject.getString("pass") , duration).show();
        nemail[i]=jObject.getString("email");
        npass[i]=jObject.getString("pass");

    }

在日志中的猫，我可以看到：JSON字符串必须以{......

In the log cat i can see : The json string must begin with "{"....

推荐答案

试试这个

$posts['data'] = $post;
//echo "SUCCESS";
header('Content-type: application/json');
echo json_encode($posts);
