PHP_Android交互

PHP代碼：

<?php
include 'SqlHelper.php';
$ress = mysql_query("select dTitle from diarys");// where dCreateUser='".$name."'", $conn)or die('QueryError');
$resFetch=mysql_fetch_array($ress);

//數據和Json轉換

$js1= json_encode($resFetch);
print "[";
print $js1;
print "]";

?>

Android代碼：

//得到Json字符串

private String startUrlCheck() {
HttpClient client = new DefaultHttpClient();

StringBuilder builder = new StringBuilder();

HttpGet myget = new HttpGet(
"http://192.168.1.111/diarytest/showlist.php");
HttpGet myget2 = new HttpGet(
"http://192.168.1.111/WebSite/Homepage.php");
try {
httpResponse = client.execute(myget2);
httpResponse = client.execute(myget);
HttpEntity httpEntity = httpResponse.getEntity();
if (httpEntity != null) {
InputStream inputStream = httpEntity.getContent();
jsonData = convertStreamToString(inputStream);

}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
client.getConnectionManager().shutdown();
httpResponse = null;
}
return jsonData;

}

public static String convertStreamToString(InputStream is) {
BufferedReader reader = null;
try {
reader = new BufferedReader(new InputStreamReader(is, "UTF-8"),// ��ֹģ�����ϵ�����
512 * 1024);
} catch (UnsupportedEncodingException e1) {

e1.printStackTrace();
}
StringBuilder sb = new StringBuilder();

String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line);
}
} catch (IOException e) {
Log.e("DataProvier convertStreamToString", e.getLocalizedMessage(),
e);
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}

 

//解釋Json字符串
