Android Json解析

Question

我已经使用httppost将json对象从android发送到我的php文件，我的java代码是

    JSONObject json = new JSONObject();
    try
    {
        json.put("email", "15");

    }
    catch (JSONException e)
    {

        e.printStackTrace();
    }
    String url = "http://xxxx.in/xxx/xxx.php";
    HttpResponse re;
    String temp = new String();
    try
    {
        re = HTTPPoster.doPost(url, json);
        temp = EntityUtils.toString(re.getEntity());
        Log.d("Main",temp);
    }
    catch (ClientProtocolException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    catch (IOException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    if (temp.compareTo("SUCCESS")==0)
    {
        Toast.makeText(this, "Sending complete!", Toast.LENGTH_LONG).show();
    }

    public class HTTPPoster
 {
public static HttpResponse doPost(String url, JSONObject c) throws ClientProtocolException, IOException 
{
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost request = new HttpPost(url);
    HttpEntity entity;
    StringEntity s = new StringEntity(c.toString());

    s.setContentEncoding((Header) new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
    entity = s;
    request.setEntity(entity);
    HttpResponse response;
    response = httpclient.execute(request);
    return response;
}
}

我的php代码是

$data = json_decode( $_POST['json'] );
echo $data['email'];
echo "working";

我得不到$data‘’email‘内容，只有工作才能恢复

How to post JSON to PHP with curl

使用file_get_contents('php://input');代替$_POST['json']

您创建的是JsonObject而不是JsonArray，因此尝试执行以下操作：

echo $data->email;
