PHP和Bing Translation API

Question

我已经在Azure Marketplace注册,我有一个客户端ID和客户端"秘密",但到目前为止我尝试过的所有内容都会导致"400 Bad Request"错误.非常感谢!

这是我一直在尝试的代码的相当基本的示例(我已经编辑了客户端ID和秘密值).我的操作是因为post变量可以通过URL请求传递...我希望这是正确的.

$authURL = 'http://datamarket.accesscontrol.windows.net/v2/OAuth2-13&grant_type=client_credentials&client_id={CLIENT_ID VALUE HERE}&client_secret={CLIENT_SECRET VALUE HERE}&scope=http://api.microsofttranslator.com';
$chpre = curl_init();
curl_setopt($chpre, CURLOPT_URL, $authURL );
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
$xpre = curl_exec($chpre);

$texttobetranslated = "???? ?????";
$BingURL = "http://api.microsofttranslator.com/v2/Http.svc/Translate?text=" . $texttobetranslated . "&from=ar&to=en";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $BingURL );
$x = curl_exec($ch);

我创建了一个易于使用且易于集成到任何PHP项目的小PHP类.你可以在这里找到它.这是代码:

  <?php
    class BingTranslation
    {
        public $clientID;
        public $clientSecret;

        public function __construct($cid, $secret)
        {
            $this->clientID = $cid;
            $this->clientSecret = $secret;
        }

        public function get_access_token()
        {   
            //if access token is not expired and is stored in COOKIE
            if(isset($_COOKIE['bing_access_token']))
                return $_COOKIE['bing_access_token'];

            // Get a 10-minute access token for Microsoft Translator API.
            $url = 'https://datamarket.accesscontrol.windows.net/v2/OAuth2-13';
            $postParams = 'grant_type=client_credentials&client_id='.urlencode($this->clientID).
            '&client_secret='.urlencode($this->clientSecret).'&scope=http://api.microsofttranslator.com';

            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $url); 
            curl_setopt($ch, CURLOPT_POSTFIELDS, $postParams);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);  
            $rsp = curl_exec($ch); 
            $rsp = json_decode($rsp);
            $access_token = $rsp->access_token;

            setcookie('bing_access_token', $access_token, $rsp->expires_in);

            return $access_token;
        }

        public function translate($word, $from, $to)
        {
            $access_token = $this->get_access_token();
            $url = 'http://api.microsofttranslator.com/V2/Http.svc/Translate?text='.$word.'&from='.$from.'&to='.$to;

            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $url); 
            curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization:bearer '.$access_token));
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);  
            $rsp = curl_exec($ch); 

            preg_match_all('/<string (.*?)>(.*?)<\/string>/s', $rsp, $matches);

            return $matches[2][0];
        }

        public function translate2($word, $from, $tos)
        {
            //translates 1 word to several languages
            //$tos is array of languages to translate to
            //returns array of translations as $result['en']=>'Hello'

            $access_token = $this->get_access_token();

            $result[$from] = $word;

            foreach($tos as $to)
            {
                $url = 'http://api.microsofttranslator.com/V2/Http.svc/Translate?text=hello&from='.$from.'&to='.$to;

                $ch = curl_init();
                curl_setopt($ch, CURLOPT_URL, $url); 
                curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization:bearer '.$access_token));
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);  
                $rsp = curl_exec($ch); 

                preg_match_all('/<string (.*?)>(.*?)<\/string>/s', $rsp, $matches);

                $result[$to] = $matches[2][0];
            }

            return $result;
        }
    }
 ?>
