我正在创建android应用程序，其中有一个搜索模块，用户输入数据然后发送到服务器，服务器将输出发送回用户，并以表格的形式显示。
我的问题是我收到此错误

这是我的网络代码，这里是link to complete code。抱歉，因为它很长，所以无法添加。
public class GetDatafromDB_Searchresult {
public String getDataFromDB() {
try {
httpclient = new DefaultHttpClient();
httppost = new HttpPost("http://192.168.0.106/test/search1.php"); // make sure the url is correct.
//add your data
nameValuePairs = new ArrayList<NameValuePair>(2);
// Always use the same variable name for posting i.e the android side variable name and php side variable name should be similar,
nameValuePairs.add(new BasicNameValuePair("carat1", strcolor1.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("carat2", strcolor2.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("color1", strclarity1.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("color2", strclarity2.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("cut1", strcut1.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("cut2", strcut2.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("shape1", strshape1.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("shape2", strshape2.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("stones", strstone.toString().trim()));
// $Edittext_value = $_POST['Edittext_value'];
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
//Execute HTTP Post Request
response = httpclient.execute(httppost);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
final String response1 = httpclient.execute(httppost, responseHandler);
System.out.println("Response : " + response1);
} catch (Exception e) {
System.out.println("Exception : " + e.getMessage());
}
return response1.trim();
}
}
这是我的服务器端代码
<?php
$hostname_localhost ="localhost";
$database_localhost ="testdb";
$username_localhost ="root";
$password_localhost ="";
$localhost = mysql_connect($hostname_localhost,$username_localhost,$password_localhost)
or
trigger_error(mysql_error(),E_USER_ERROR);
mysql_select_db($database_localhost, $localhost);
$carat1 = $_POST['carat1'];
$carat2 = $_POST['carat2'];
$color1 = $_POST['color1'];
$color2 = $_POST['color2'];
$cut1 = $_POST['cut1'];
$cut2 = $_POST['cut2'];
$shape1 = $_POST['shape1'];
$shape2 = $_POST['shape2'];
$stones = $_POST['stones'];
$query_search ="Select * from search1 where
carats = $carat1 and carats = $carat2 and
color = '$color1' or color = '$color2' and
cut = '$cut1' or cut = '$cut2' and
shape = '$shape1' or shape = '$shape2' and
stone ='$stones'";
$query_exec = mysql_query($query_search) or die(mysql_error());
while($row=mysql_fetch_assoc($query_exec))
$json_output[]=$row;
echo json_encode($json_output);
mysql_close();
?>
编辑： 这是服务器的输出。

答案 0 :(得分：0)
您似乎没有正确收到回复。尝试这样的事情......
HttpResponse response = defaultHttpClient.execute(httppost);
InputStream data = response.getEntity().getContent();
