我认为Android方面没有任何问题，但这是我发送信息的方式：

这是我正在使用的PHP脚本：
URL url = new URL(URL_);
HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection();
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setDoOutput(true);
httpURLConnection.setDoInput(true);
OutputStream outputStream = httpURLConnection.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream, UTF));
String data =
URLEncoder.encode(USER_ID, UTF) + "=" + URLEncoder.encode(_id, UTF) + "&" +
URLEncoder.encode(PRIMARY_INFO, UTF) + "=" + URLEncoder.encode(primary, UTF) + "&" +
URLEncoder.encode(SECONDARY, UTF) + "=" + URLEncoder.encode(secondary, UTF) + "&" +
URLEncoder.encode(THIRD, UTF) + "=" + URLEncoder.encode(third, UTF) + "&" +
URLEncoder.encode(TIMESTAMP, UTF) + "=" + URLEncoder.encode(time_stamp, UTF);
bufferedWriter.write(data);
bufferedWriter.flush();
bufferedWriter.close();
outputStream.close();
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream,"iso-8859-1"));
String response = "";
String line = "";
while ((line = bufferedReader.readLine())!=null)
{
response+= line;
}
bufferedReader.close();
inputStream.close();
httpURLConnection.disconnect();
return response;
