java - 如何在php中接收POST

Question

我正在尝试从我的 Android 客户端将数据发送到 php 端，下面是代码:

(我从互联网上的各种来源构建了此代码，因此我不确定这里是否一切正常)

private void postJSON(String myurl) throws IOException {
        java.util.Date date= new java.util.Date();
        Timestamp timestamp = (new Timestamp(date.getTime()));
        try {
            JSONObject parameters = new JSONObject();
            parameters.put("timestamp",timestamp);
            parameters.put("jsonArray", new JSONArray(Arrays.asList(makeJSON())));
            parameters.put("type", "Android");
            parameters.put("mail", "xyz@gmail.com");
            URL url = new URL(myurl);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            //  conn.setReadTimeout(10000 /* milliseconds */);
            //  conn.setConnectTimeout(15000 /* milliseconds */);
            conn.setRequestProperty( "Content-Type", "application/json" );
            conn.setDoOutput(true);
            conn.setRequestMethod("POST");
            OutputStream out = new BufferedOutputStream(conn.getOutputStream());
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
            writer.write(parameters.toString());
            writer.close();
            out.close();

            int responseCode = conn.getResponseCode();
            System.out.println("\nSending 'POST' request to URL : " + url);
            System.out.println("Response Code : " + responseCode);

            BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String inputLine;
            StringBuffer response = new StringBuffer();

            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();
            System.out.println(response.toString());

        }catch (Exception exception) {
            System.out.println("Exception: "+exception);
        }
    } 

我对这一行感到困惑:

writer.write(parameters.toString());

本质上我只发送一个字符串到 php 端。我如何在那里收到它？ POST 变量名称是什么？

我对android完全没有经验，但是我猜测要么是某种数组，要么是json，你可以通过使用<?php echo var_dump($_POST); ?>创建一个页面来查看它发送的内容。并将 POST 请求发送到页面。
