我正在开发一个应用程序,其中我使用外部 Ms Access 数据库(在 PC 上)作为我的 android 应用程序的数据库。我已经使用 PHP for Android 完成了 MySql 和 MSSql 的连接,但我想知道如何继续使用 MS Access 数据库。
欢迎任何教程或片段!
1)在Android端做一个这样的功能:
public void connect_access_php(String vars)
{
List<NameValuePair> itemstring = new ArrayList<NameValuePair>();
itemstring.add(new BasicNameValuePair("VARIABLE", vars));
HttpClient httpclient = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(httpclient.getParams(), 10000); //Timeout Limit
try
{
HttpPost httppost = new HttpPost("url_of_php_file");
httppost.setEntity(new UrlEncodedFormEntity(itemstring));
HttpResponse response = httpclient.execute(httppost);
InputStream content = response.getEntity().getContent();
BufferedReader buffer = new BufferedReader(new InputStreamReader(content));
String s;
while ((s = buffer.readLine()) != null) {
//Handle your Values here
}
}catch (Exception e) {
Toast.makeText(getApplicationContext(),"Connection Problem !", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
2)然后在php页面上,与access文件进行连接如下:
<?php
$variab = $_REQUEST['VARIABLE'];
$conn = new COM("ADODB.Connection") or die("Oops!");
$conn->Open("DRIVER={Microsoft Access Driver (*.mdb)};DBQ=C:\Documents and Settings\xxxx\Desktop\access_file.mdb");
$query = "SELECT * FROM table WHERE (Variable = '".$variab."')";
$data = $conn->Execute($query);
while (!$data->EOF)
{
echo $data ->Fields[0]->value . ":";
//echo $data ->Fields[1]->value . " \n";
$data ->MoveNext();
}
?>
使用此示例,您可以将变量传递给 php 脚本,从而访问 CRUD 函数的文件。
祝你好运!!
