這是一個 AP , 用來展示如何向微軟存取服務的 token. 以及如何搭配這個 token 呼叫語音合成 method 的例子.

  1. cpp
  2. project

Outline

  1. 註冊 Azure Marketplace 你的應用程式
  2. 開始寫程式


註冊 Azure Marketplace 你的應用程式

Step 1: 註冊 Azure Marketplace

開始寫程式

Step 1: Add reference libraries. [Add Reference] -> [.NET]

  • System.Runtime.Serialization .dll for System.Runtime.Serialization.Json
  • System.ServiceModel .dll for System.ServiceModel.Channels
  • 把 [C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Web.dll] 加進來 (一定要

System.Runtime Serialization

System.ServiceModel

System.Web (請使用 2.0.50727)

Step 2: 取得 authentication token

// 查閱 client id & client secret:

// https://datamarket.azure.com/developer/applications/


String strClientID= "<client id>";
String strClientSecret = "<client secret>";


AdmAuthentication admAuth = new AdmAuthentication(strClientID, strClientSecret);
admToken = admAuth.GetAccessToken(); // 取得 access token

// 輔助 class: 幫我們利用 Post 的方式, 向微軟取得 access token

// 申請窗口: https://datamarket.accesscontrol.windows.net/v2/OAuth2-13";
// 要求的權限 (scope): http://api.microsofttranslator.com
public class AdmAuthentication {
…
}

Step 3: 使用 Speak method 搭配著 token, 要求說話.

// Speak API 介面: http://api.microsofttranslator.com/v2/Http.svc/Speak
// authToken= "Bearer " + <剛剛得到的 token 字串>;

private static void Speak(string authToken){

        string strtext = “井民全”;
        string string strLanguage="zh-tw";
        string uri = http://api.microsofttranslator.com/v2/Http.svc/Speak?appId=&text= 
                                 +HttpUtility.UrlEncode(strtext) + "&language=" + strLanguage;

// 組合 Speak 指令
        HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(uri);
        httpWebRequest.Headers.Add("Authorization", authToken);

// 送出指令
        response = httpWebRequest.GetResponse();

// 建立媒體播放器, 播放 Server 回傳的合成語音
        using (Stream stream = response.GetResponseStream()) {
                     using (SoundPlayer player = new SoundPlayer(stream)) {
                                  player.PlaySync();
                     }
         }
} // end of speak method
