我有一个应用程序可以生成这个json数组：[{＆＃34; Name＆＃34;：＆＃34; Apple＆＃34;，＆＃34; Quantity＆＃34;：＆＃34; 8＆＃34; }， {＆＃34;名称＆＃34;：＆＃34;牛肉＆＃34;＆＃34;数量＆＃34;：＆＃34; 9＆＃34;}，{＆＃34;名称＆＃34;：＆＃ 34; Vegitable＆＃34;＆＃34;数量＆＃34;：＆＃34; 5＆＃34;}]
我正在使用json解析器类将此数组发送到本地主机中的php文件。该应用程序成功地将数据发布到php文件，但作为回报获得此垃圾值。 logcat视图是

我无法弄清楚问题所在，以及如何从我的本地主机中的php文件接收应用程序生成的json数组。所以请有人帮我解决这个问题。
这是我的JsonParse类：
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getandpostJSONFromUrl(String url, String method,JSONArray name) {
// Making HTTP request
try {
// defaultHttpClient
if (method.equals("POST") ) {
// request method is POST
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
Log.d("Json Array content",""+name);
StringEntity se=new StringEntity(name.toString());
Log.e("Json Array content",""+se);
se.setContentType("application/json;charset=UTF-8");
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
httpPost.setEntity(se);
HttpResponse httpResponse = httpClient.execute(httpPost);
httpPost.setHeader("json",json.toString());
// HttpEntity httpEntity = httpResponse.getEntity();
int response = httpResponse.getStatusLine().getStatusCode();
// is = httpEntity.getContent();
// Log.e("posting Status", "Post status: " + response);
String text = null;
if(response==200){
HttpEntity entity=httpResponse.getEntity();
text=EntityUtils.toString(entity);
try {
JSONArray jsonArray = new JSONArray(text);
//text=jsonArray.getJSONObject(0).getJSONArray(name);
text=jsonArray.getString(0);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String tag=text;
Log.d(tag, text);
}
}
if (method.equals("GET") ) {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if (method == "POST") {
try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is));
} catch (Exception e) {
Log.e("Buffer error", "Buffer error" + e);
}
} else if (method == "GET") {
try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
}
// return JSON String
return jObj;
}
}
这是我用来获取json数组的php文件：
<?php
define('DB_NAME', 'a1422982_sshop');
define('DB_USER', 'root');
define('DB_PASSWORD', '');
define('DB_HOST', 'localhost');
$link = mysql_connect(DB_HOST,DB_USER,DB_PASSWORD);
if(!$link){
die('could not connect: '.msql_error());
}
$db_selected=mysql_select_db(DB_NAME, $link);
if(!$db_selected){
die('Can not use '.DB_NAME.':'.mysql_error());
}
$jarray = $_POST['json'];
$parsed = json_decode($jarray , true);
foreach ($parsed as $obj) {
$ProductName = $obj['Name'];
$ProductQuantity= $obj['Quantity'];
echo $ProductName." ".$ProductQuantity;
}
?>
