java - URL 处的 FileNotFoundException

Question

我正在尝试从 php url 获取请求。运行时发生文件未找到异常。我在下面的代码中提到了错误行。Stacktrace 似乎没有从 url 获取响应。

        {
         List<SuggestGetSet> ListData = new ArrayList<SuggestGetSet>();
         try {

            URL js = new URL("example.php"+temp);

            Log.d("URL","Connection"+js);

            URLConnection urlConnection  = js.openConnection();
            BufferedReader reader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));  ---32 nd line
            String line = reader.readLine();
            JSONObject jsonResponse = new JSONObject(line);
            JSONArray jsonArray = jsonResponse.getJSONArray("search");
            for(int i = 0; i < jsonArray.length(); i++){
                JSONObject r = jsonArray.getJSONObject(i);
                ListData.add(new SuggestGetSet(r.getString("id"), 
r.getString("name")));
            }
        } catch (Exception e1) {

            e1.printStackTrace();
        }
         return ListData;

        }

尝试替换此行

String temp=sName.replace(" ","%20");
URL js = new URL("http://192.11.my api.php"+temp);

与

String temp=URLEncoder.encode("http://192.11.my api.php/"+sName, "UTF-8");
URL js = new URL(temp);
