如何获取Microsoft Translator API的身份验证令牌？

Question

我想获取Microsoft Translator API的身份验证令牌。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); 


?> 

它给了我下面的错误： {“的StatusCode”：401，“消息”：“由于缺少订阅密钥拒绝访问确保发出请求时，包括订阅密钥一个API“。 }

这可能意味着密钥根据下面的网站无效，但我确保密钥在同一网站上有效。

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

我做了网上关于如何让Authenticationtoken找到一些例子，但它们已经过时。

我怎样才能获得AuthenticationToken /实现微软认识我的钥匙？

你传递订阅的关键错误 - ？ 的订购金钥应在头部（OCP-APIM-认购键）或在URL中的查询参数传递订阅密钥=

而且您应该使用由Azure认知服务仪表板生成的Key1或Key2。

仅供参考 - M $已经提供用于测试的令牌生成，这应该给你一个线索被使用的按键为此目的： http://docs.microsofttranslator.com/oauth-token.html

这里是它转换为字符串从EN到工作的PHP脚本FR（它是基于一个叫做由BoLiQuan WP-弹头，翻译过时的WP插件，我已经修改了这一目的）：

<?php 
 

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

将您的密钥也添加到URL中。

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

但是，在CURLOPT_POSTFIELDS也可以。
