授权问题沃森文本到语音转换从Java脚本

我想使用沃森文本到语音服务的JavaScript代码。但是，我试图让它工作。授权问题沃森文本到语音转换从Java脚本

如果我使用下面的代码：

$.ajax({ 
       url: 'https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize', 
       type: 'POST', 
       headers: {"Content-Type": "application/json", "Accept": "audio/*", "Authorization": "Basic SomethingSomethingSomething=="}, 
       text: msgData.message[0].cInfo.text, 
       output: 'output.wav', 
       success: function() { 
        console.log("text to voice complete"); 
        var audio = new Audio('output.wav'); 
        audio.play(); 
       } 
      });

我得到：

无法加载 https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize：请求头字段授权不被访问控制允许报头允许在飞行前响应。

请注意，我可以很容易地得到这样的要求是从Restlet工作。

不过，如果我使用：

$.ajax({ 
         url: 'https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize', 
         type: 'POST', 
         user: {"something": "something"}, 
         headers: {"Content-Type": "application/json", "Accept": "audio/*"}, 
         data: {"text": msgData.message[0].cInfo.body}, 
         output: 'output.wav', 
         success: function() { 
           console.log("text to voice complete"); 
           var audio = new Audio('output.wav'); 
           audio.play(); 
         } 
       });

我得到：

stream.watsonplatform.net/text-to-speech/api/v1/synthesize:1 POST https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize 401 (Processed) 
index.html:1 Failed to load https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://52.207.232.200' is therefore not allowed access. The response had HTTP status code 401.
