在尝试构建我的第一个与远程服务器文件通信的应用程序时，我试图从Android应用程序访问本地服务器上的php文件（带有硬编码数据）。问题是php文件正在返回xml数据，而不是json但是我已经放了
标题（＆＃39; content-type：application / json; charset = utf-8＆＃39;）
确保只返回json但没有用。下面是我的andoroid应用程序和php文件的代码。有人可以帮忙吗？我还把log cat只显示了一堆xml标签，但没有显示数据
活动代码段
String responseString;
responseString = com.rrdtech.example.generic.GenericUtility.getResponse(url_all_products);
Log.i("inside doinbg=",responseString);
下面的getresponse（url）代码
public static String getResponse (String url)
{
HttpEntity entity = null;
StringBuilder sb = null;
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpGet httppost = new HttpGet(url);
Log.e("log_tag_htppost", httppost.toString());
HttpResponse response = httpclient.execute(httppost);
entity = response.getEntity();
InputStream is = entity.getContent();
Log.e("log_tag", "after input stream");
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line="0";
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
is.close();
}catch(Exception e)
{
Log.e("log_tag", "Error in http connection"+e.toString());
}
return sb.toString();
}
LOG CAT值低于......我已经用标签doinbg

这不是xml。这是带错误的HTML。它说：
Access to the requested object is only available from the local network
因此，您应该正确配置服务器。

由于跛脚我面临的错误。我试图找出解决方案，并发现一些链接/博客说更新httpd-xampp.cnf文件，包括字符串“允许所有”，但它帮助了很多人，但不是我的情况。我已经拥有我的网站托管所以我把PHP文件放在那里，我能够得到json对象输出。感谢大师的帮助！
