<?php
//宣告使用utf-8編碼
header("Content-Type:text/html; charset=utf-8");
$user=$_POST['login_user'];
$pass=$_POST['login_pw'];
echo "login_user=".$user.";login_pw=".$pass;
?>
我們可以先使用以下表單來驗證網頁功能
<html>
<body>
測試POST資料傳送：
<form method="POST" action="http://163.22.249.40/myPHP/httppost.php">
帳號:
<input type="text" name="login_user" size="20"value="sswu" /><br />
密碼:
<input type="text" name="login_pw" size="20" value="1234" /><br />
<input type="submit" name="btnSend" value="送出" /><br />
</form>
</body>
</html>
HTTP POST與HTTP GET主要差異在於參數資料傳遞方式，使用POST方式時必須使用setEntity()設定POST參數，程式如下：
String Url = "http://my_webserver/httppost.php";
//設定POST參數
List
postData.add(new BasicNameValuePair("login_user", "sswu"));
postData.add(new BasicNameValuePair("login_pw", "0123"));
String result = httpGET(Url, postData);
if (result == null) {
//顯示錯誤訊息
}
...
/**
* Issue a POST request to the server.
* @param url POST address.
* @param params request parameters.
*/
private String httpPOST(String url, List
HttpPost post = new HttpPost(url);
try {
//送出HTTP request
post.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
//取得HTTP response
HttpResponse httpResponse = new DefaultHttpClient().execute(post);
//檢查狀態碼，200表示OK
if (httpResponse.getStatusLine().getStatusCode()==200){
//取出回應字串
String strResult = EntityUtils.toString(httpResponse.getEntity());
return strResult;
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
