我正在创建应用程序，其中用户输入数据进行搜索，然后应用程序将其发送到服务器，然后服务器将搜索结果发送回客户端。
我得到错误，我不能理解它的意思。我从服务器得到确切的结果。
这是我的网络代码从那里的应用程序，这里是链接到完整的代码
public class GetDatafromDB_Searchresult {
String response1 ;
public String getDataFromDB() {
httpclient = new DefaultHttpClient();
httppost = new HttpPost("http://192.168.0.106/test/search.php"); // make sure the url is correct.
//add your data
nameValuePairs = new ArrayList<NameValuePair>();
// 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", strcarat1.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("carat2", strcarat2.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("carat1", strcolor1.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("carat2", strcolor2.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("clarity1", strclarity1.toString().trim()));
nameValuePairs.add(new BasicNameValuePair("clarity2", 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
try {
response = httpclient.execute(httppost);
HttpEntity entity= response.getEntity();
{
if(entity!=null)
{
entity.consumeContent();
}
}
ResponseHandler<String> responseHandler = new BasicResponseHandler();
response1 = httpclient.execute(httppost, responseHandler);
System.out.println("Response : " + response1);
} catch (Exception e) {
e.printStackTrace();
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'];
$clarity1 = $_POST['clarity1'];
$clarity2 = $_POST['clarity2'];
$color1 = $_POST['color1'];
$color2 = $_POST['color2'];
$cut1 = $_POST['cut1'];
$cut2 = $_POST['cut2'];
$shape1 = $_POST['shape1'];
$shape2 = $_POST['shape2'];
$stones = $_POST['stones'];
$query_search ="Select * from search1 where carats Between '$carat1' and '$carat2' and
color = '$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($json_output);
mysql_close();
?>
我也改变了echo json_encode($json_output);打印(json_encode (json_output美元));输出仍然没有变化
下面是我的logcat的输出。

您从数据库返回HTML代码，您应该从数据库更改语句的结果。
问题:你忘了在这个php参数
的NameValuePairs中加入color参数 $color1 = $_POST['color1'];
$color2 = $_POST['color2'];
