我收到此错误Error parsing <!DOCTYPE HTML...
,就像找不到资源一样,但我传递的是正确的网址:
“http://10.0.2.2/portablevision/webservice.php”;
无论如何,这是我的PHP网络服务:
<?php
$response = array();
require_once __DIR__ . '/db_connect.php';
$db = new DB_CONNECT();
$result = mysql_query("SELECT * FROM words") or die(mysql_error());
if(mysql_num_rows($result) > 0){
$response["words"] = array();
while($row = mysql_fetch_array($result)){
$word = array();
$word["id"] = $row["id"];
$word["word"] = $row["word"];
array_push($response["words"], $word);
}
$response["success"] = 1;
echo json_encode($response);
}
else{
$response["success"] = 0;
$response["message"] = "No word found";
echo json_encode($response);
}
?>
Android活动:
public class MainActivity extends Activity{
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> wordsList;
private static String url_webservice = "http://10.0.2.2/portablevision/webservice.php";
private static final String TAG_SUCCESS = "success";
private static final String TAG_WORDS = "words";
JSONArray palavras = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wordsList = new ArrayList<HashMap<String,String>>();
List<NameValuePair> params = new ArrayList<NameValuePair>();
JSONObject json = jParser.makeHttpRequest(url_webservice, "GET", params);
Log.d("All words", json.toString());
try{
int success = json.getInt(TAG_SUCCESS);
if(success == 1){
words = json.getJSONArray(TAG_WORDS);
for(int i = 0; i < words.length; i++){
JSONObject c = words.getJSONObject(i);
String id = c.getString("id");
String word = c.getString("word");
HashMap<String, String> map = new HashMap<String, String>();
map.put("id", id);
map.put("word", word);
wordsList.add(map);
}
}
else{
Toast.makeText(MainActivity.this, "Unable to load words", Toast.LENGTH_LONG).show();
}
}
catch(JSONException e){
Toast.makeText(MainActivity.this, "Erro: " + e.getMessage(), Toast.LENGTH_LONG).show();
}
}
JSONParser类:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
public JSONParser(){}
public JSONObject makeHttpRequest(String url, String method, List<NameValuePair> params){
try{
if(method == "POST"){
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
else if(method == "GET"){
DefaultHttpClient httpClient = new DefaultHttpClient();
String paramString = URLEncodedUtils.format(params, "utf-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
}
catch(UnsupportedEncodingException e){
e.printStackTrace();
}
catch(ClientProtocolException e){
e.printStackTrace();
}
catch(IOException e){
e.printStackTrace();
}
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "utf-8"), 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{
jObj = new JSONObject(json);
}
catch(JSONException e){
Log.e("JSON Parser", "Error parsing data " + json.toString());
}
return jObj;
}
}
JSON的结果是正确的:
{"words":[{"id":"1","word":"correct place"}],"success":1}
欢迎任何帮助
