我想使用沃森文本到語音服務的JavaScript代碼。 但是,我試圖讓它工作。授權問題沃森文本到語音轉換從Java腳本

如果我使用下面的代碼:

$.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:

無法加載 https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize: 請求頭字段授權不被 訪問控制允許報頭允許在飛行前響應。

請注意,我可以很容易地得到這樣的要求是從Restlet工作。

不過,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.

它看起來像IBM沃森文本到語音不支持部分 CORS(需要你的情況)。請檢查答案: Can't access IBM Watson API locally due to CORS on a Rails/AJAX App

而且,你會發現有一個明智的建議,通知您不要在你的JavaScript代碼添加您的沃森憑據,而是使用令牌: https://console.bluemix.net/docs/services/watson/getting-started-tokens.html#tokens-for-authentication

正如你「重新在客戶端的工作,也許嘗試沃森的NPM模塊或庫(帶有示例)將是一個不錯的選擇:

希望這有助於!
