如何获得 Microsoft Translator API 的身份验证令牌？

Question

我想为 Microsoft Translator API 获取身份验证令牌。这是我的代码：

<?php

//1. initialize cURL
$ch = curl_init();

//2. set options

//Set to POST request
curl_setopt($ch, CURLOPT_POST,1);

// URL to send the request to
curl_setopt($ch, CURLOPT_URL, 'https://api.cognitive.microsoft.com/sts/v1.0/issueToken');

//return instead of outputting directly
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//whether to include header in the output. here set to false
curl_setopt($ch, CURLOPT_HEADER, 0);

//pass my subscription key
curl_setopt($ch, CURLOPT_POSTFIELDS,array(Subscription-Key => '<my-key>'));

//CURLOPT_SSL_VERIFYPEER- Set to false to stop verifying certificate
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

//3. Execute the request and fetch the response. check for errors
$output = curl_exec($ch);

if ($output === FALSE) {
    echo "cURL Error" . curl_error($ch);
}

//4. close and free up the curl handle
curl_close($ch);

//5. display raw output
print_r($output);


?>

它给我以下错误： { "statusCode": 401, "message": "Access denied due to missing subscription key. Make sure to include subscription key when making requests to an API." }

根据下面的网站，这可能意味着密钥无效，但我确保密钥在同一网站上有效。

http://docs.microsofttranslator.com/oauth-token.html

我确实在网上找到了一些关于如何获取 Authenticationtoken 的示例，但是它们已经过时了。

Answer 1

你传错了 subscription-key - 订阅密钥应在 header (Ocp-Apim-Subscription-Key) 中传递或作为 URL 中的查询字符串参数传递？Subscription-Key=

并且您应该使用 Azure 认知服务仪表板生成的 Key1 或 Key2。

仅供参考 - M$ 已经制作了一个可用于测试目的的令牌生成器，这应该可以让您了解哪些密钥用于哪些目的： http://docs.microsofttranslator.com/oauth-token.html

这是一个有效的 PHP 脚本，可将字符串从 EN 转换为 FR（它基于 BoLiQuan 的一个名为 Wp-Slug-Translate 的过时 WP 插件，我为此目的对其进行了修改）：

<?php

define("CLIENTID",'<client-name>'); // client name/id
define("CLIENTSECRET",'<client-key>'); // Put key1 or key 2 here
define("SOURCE","en");
define("TARGET","fr");


class WstHttpRequest
{
 function curlRequest($url, $header = array(), $postData = ''){
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  if(!empty($header)){
   curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
  }
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  if(!empty($postData)){
   curl_setopt($ch, CURLOPT_POST, TRUE);
   curl_setopt($ch, CURLOPT_POSTFIELDS, is_array($postData) ? http_build_query($postData) : $postData);
  }
  $curlResponse = curl_exec($ch);
  curl_close($ch);
  return $curlResponse;
 }
}

class WstMicrosoftTranslator extends WstHttpRequest
{
 private $_clientID = CLIENTID;
 private $_clientSecret = CLIENTSECRET;
 private $_fromLanguage = SOURCE;
 private $_toLanguage = TARGET;

 private $_grantType = "client_credentials";
 private $_scopeUrl = "http://api.microsofttranslator.com";
 private $_authUrl = "https://api.cognitive.microsoft.com/sts/v1.0/issueToken";
 
 // added subscription-key
 private function _getTokens(){
  try{
   $header = array('Ocp-Apim-Subscription-Key: '.$this->_clientSecret);
   $postData = array(
    'grant_type' => $this->_grantType,
    'scope' => $this->_scopeUrl,
    'client_id' => $this->_clientID,
    'client_secret' => $this->_clientSecret
   );
   $response = $this->curlRequest($this->_authUrl, $header, $postData);
   if (!empty($response))
    return $response;  
  }
  catch(Exception $e){
   echo "Exception-" . $e->getMessage();
  }
 }

 function translate($inputStr){
  $params = "text=" . rawurlencode($inputStr) . "&from=" . $this->_fromLanguage . "&to=" . $this->_toLanguage;
  $translateUrl = "http://api.microsofttranslator.com/v2/Http.svc/Translate?$params";
  $accessToken = $this->_getTokens();
  $authHeader = "Authorization: Bearer " . $accessToken;
  $header = array($authHeader, "Content-Type: text/xml");
  $curlResponse = $this->curlRequest($translateUrl, $header);
  
  $xmlObj = simplexml_load_string($curlResponse);
  $translatedStr = '';
  foreach((array)$xmlObj[0] as $val){
   $translatedStr = $val;
  }
  return $translatedStr;
 }

}

function bing_translator($string) {
 $wst_microsoft= new WstMicrosoftTranslator();
 return $wst_microsoft->translate($string);
}

echo bing_translator("How about translating this?");
?>

Answer 2

也在 URL 中添加您的密钥。

curl_setopt($ch, CURLOPT_URL, 'https://api.cognitive.microsoft.com/sts/v1.0/issueToken?Subscription-Key={your key}');

但也将其保留在 CURLOPT_POSTFIELDS。
