我正在寫一個與Twitter API集成的基本Web應用程序。我使用jQuery和AJAX請求身份驗證令牌Twitter require,但我違反了異步跨站點請求策略或任何它。JSONP郵政代理
我會使用JSONP,但Twitter API需要POST。我讀過我應該使用一個itermediate代理。我不知道這涉及到什麼,也找不到任何資源?我可以用PHP編寫。
任何人都可以解釋什麼是代理頁面?
UPDATE
繼閱讀接受的答案下面我寫了一個PHP代理腳本,這是我想出了和得到了工作:
<?php
class proxy {
public $serviceURL;
public $postString;
public $headers;
public $response;
public function __construct($url) {
$this->serviceURL = $url;
$this->postStringify($_POST);
}
private function postStringify($postArray) {
$ps = '';
foreach($postArray as $key => $value) {
$ps .= $key . '=' . $value . '&';
}
rtrim($ps, '&');
$this->postString = $ps;
}
private function isCurlInstalled() {
return (in_array('curl', get_loaded_extensions())) ? true : false;
}
public function makeRequest() {
if ($this->isCurlInstalled()) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $this->serviceURL);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POSTFIELDS, $this->postString);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->headers);
$this->response = curl_exec($ch);
if ($this->response === false) $this->response = curl_error($ch);
curl_close($ch);
} else {
$this->response = 'Need to install Curl!';
}
return $this->response;
}
public function debug() {
var_dump($this->response);
}
}
?>
,並在另一個文件,AJAX請求電話:
<?php
include ('proxy.php');
ini_set('display_errors',1);
error_reporting(E_ALL);
$consumerKey = 'myKEY!';
$consumerSecret = 'mySecret!';
$bearerTokenCredentials = $consumerKey . ':' . $consumerSecret;
$base64TokenCredentials = base64_encode($bearerTokenCredentials);
$authProxy = new proxy('https://api.twitter.com/oauth2/token/');
$authProxy->headers = array(
'Content-Type: application/x-www-form-urlencoded',
'Authorization: Basic ' . $base64TokenCredentials,
);
$response = $authProxy->makeRequest();
if (is_null($response)) $authProxy->debug(); else echo $response;
?>
酷了你。我會這樣做,並在完成時標記爲正確! – 2013-04-03 20:54:34
