mysql數(shù)據(jù)庫(kù)權(quán)限，只允許localhost連接，不能通過(guò)Internet連接

字符集轉(zhuǎn)換

查詢結(jié)果集不能直接輸出，print($result)，緊緊輸出資源代碼Resource id #2

輸出了3個(gè)JSON字符串，3對(duì)大括弧

3，android客戶端如何解碼？

DefaultHttpClient httpClient = new DefaultHttpClient();

HttpPost httpPost = new HttpPost("htttp:localhost/mysql.php");

httpPost.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8));

//params:List php接收

HttpResponse httpResponse = httpClient.execute(httpPost);

HttpEntity httpEntity = httpResponse.getEntity();

is = httpEntity.getContent();

BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));

StringBuilder sb = new StringBuilder();

String line = null;

while ((line = reader.readLine()) != null) {

sb.append(line + "\n");

}

is.close();

json = sb.toString();

return new JSONObject(json);
