从Android调用PHP函数？

这是我编写的用于使用JSON注册新用户名的一段代码：

    public static boolean register(Context myContext, String name, String pwd) { byte[] data; HttpPost httppost; StringBuffer buffer; HttpResponse response; HttpClient httpclient; InputStream inputStream; List<NamevaluePair> namevaluePairs; try {         httpclient = new DefaultHttpClient();         httppost = new HttpPost(   "http://X.X.X.X/register.php");         // Add your data         namevaluePairs = new ArrayList<NamevaluePair>(2);         namevaluePairs.add(new BasicNamevaluePair("User", name.trim()));         namevaluePairs.add(new BasicNamevaluePair("Password", pwd.trim()));         httppost.setEntity(new UrlEnpredFormEntity(namevaluePairs));         // Execute HTTP Post Request         response = httpclient.execute(httppost);         inputStream = response.getEntity().getContent();         data = new byte[256];         buffer = new StringBuffer();         int len = 0;         while (-1 != (len = inputStream.read(data))) {      buffer.append(new String(data, 0, len));         }         inputStream.close(); } catch (Exception e) {         Toast.makeText(myContext, "error" + e.toString(), Toast.LENGTH_LONG)   .show();         return false; } if (buffer.charAt(0) == 'Y') {         return true; } else {         return false; }    }

如果您注意到：

 namevaluePairs = new ArrayList<NamevaluePair>(2);         namevaluePairs.add(new BasicNamevaluePair("User", name.trim()));         namevaluePairs.add(new BasicNamevaluePair("Password", pwd.trim()));         httppost.setEntity(new UrlEnpredFormEntity(namevaluePairs));

在那一部分中，您可以发送参数。

该方法只是将用户名和密码发送到register.php。如果用户已被使用，则返回“ N”；否则，返回“ N”。否则创建用户并返回“ Y”。

在服务器端，您将它们视为POST信息，因此：

 $user = $_POST['User'];

它应该为您的情况做:)

干杯!
