如何使用 REST API 获取意图How to get an intent using the REST APIs
在本文中，你将使用 LUIS 应用从会话文本中确定用户的意向。In this article, you will use a LUIS app to determine a user's intention from conversational text. 将用户的意向作为文本发送到 Pizza 应用的 HTTP 预测终结点。Send the user's intention as text to the Pizza app's HTTP prediction endpoint. 在终结点处，LUIS 应用 Pizza 应用的模型来分析自然语言文本的含义，确定总体意向并提取与应用的主题域相关的数据。At the endpoint, LUIS applies the Pizza app's model to analyze the natural language text for meaning, determining overall intent and extracting data relevant to the app's subject domain.
对于本文，需要一个免费的 LUIS 帐户。For this article, you need a free LUIS account.

先决条件Prerequisites
创建 Pizza 应用Create Pizza app
- Select pizza-app-for-luis-v6.json to bring up the GitHub page for the
pizza-app-for-luis.jsonfile. - Right-click or long tap the Raw button and select Save link as to save the
pizza-app-for-luis.jsonto your computer. - Sign into the LUIS portal.
- Select My Apps.
- On the My Apps page, select + New app for conversation.
- Select Import as JSON.
- In the Import new app dialog, select the Choose File button.
- Select the
pizza-app-for-luis.jsonfile you downloaded, then select Open. - In the Import new app dialog Name field, enter a name for your Pizza app, then select the Done button.
The app will be imported.
If you see the dialog How to create an effective LUIS app, close the dialog.
Train and publish the Pizza app
You should see the Intents page with a list of the intents in the Pizza app.
在 LUIS 网站的右上方，选择“训练”按钮。In the top-right side of the LUIS website, select the Train button.
当“训练”按钮上的状态指示器为绿色时，即表示训练完成。Training is complete when status indicator on the Train button is green.
若要在聊天机器人或其他客户端应用程序中接收 LUIS 预测，需要将应用发布到预测终结点。In order to receive a LUIS prediction in a chat bot or other client application, you need to publish the app to the prediction endpoint.
在右上方的导航栏中选择“发布”。Select Publish in the top-right navigation.
选择“生产”槽，然后选择“完成” 。Select the Production slot, then select Done.
在通知中选择“访问终结点 URL”，以转到“Azure 资源”页 。Select Access your endpoint URLs in the notification to go to the Azure Resources page. 只有你拥有与应用关联的预测资源时，才能看到 URL。You will only be able to see the URLs if you have a prediction resource associated with the app. 还可以单击“管理”来找到“Azure 资源”页 。You can also find the Azure Resources page by clicking Manage.
Your Pizza app is now ready to use.
Record the app ID, prediction key, and prediction endpoint of your Pizza app
To use your new Pizza app, you will need the app ID, prediction key, and prediction endpoint of your Pizza app.
To find these values:
- From the Intents page, select MANAGE.
- From the Application Settings page, record the App ID.
- Select Azure Resources.
- From the Azure Resources page, record the Primary Key. This value is your prediction key.
- Record the Endpoint URL. This value is your prediction endpoint.
以编程方式获取意向Get intent programmatically
使用 C# (.NET Core) 查询预测终结点并获取预测结果。Use C# (.NET Core) to query the prediction endpoint and get a prediction result.
使用项目和名为

- Visual Studio CodeVisual Studio Code
创建 Pizza 应用Create Pizza app
- Select pizza-app-for-luis-v6.json to bring up the GitHub page for the
pizza-app-for-luis.jsonfile. - Right-click or long tap the Raw button and select Save link as to save the
pizza-app-for-luis.jsonto your computer. - Sign into the LUIS portal.
- Select My Apps.
- On the My Apps page, select + New app for conversation.
- Select Import as JSON.
- In the Import new app dialog, select the Choose File button.
- Select the
pizza-app-for-luis.jsonfile you downloaded, then select Open. - In the Import new app dialog Name field, enter a name for your Pizza app, then select the Done button.
The app will be imported.
If you see the dialog How to create an effective LUIS app, close the dialog.
Train and publish the Pizza app
You should see the Intents page with a list of the intents in the Pizza app.
在 LUIS 网站的右上方，选择“训练”按钮。In the top-right side of the LUIS website, select the Train button.
当“训练”按钮上的状态指示器为绿色时，即表示训练完成。Training is complete when status indicator on the Train button is green.
若要在聊天机器人或其他客户端应用程序中接收 LUIS 预测，需要将应用发布到预测终结点。In order to receive a LUIS prediction in a chat bot or other client application, you need to publish the app to the prediction endpoint.
在右上方的导航栏中选择“发布”。Select Publish in the top-right navigation.
选择“生产”槽，然后选择“完成” 。Select the Production slot, then select Done.
在通知中选择“访问终结点 URL”，以转到“Azure 资源”页 。Select Access your endpoint URLs in the notification to go to the Azure Resources page. 只有你拥有与应用关联的预测资源时，才能看到 URL。You will only be able to see the URLs if you have a prediction resource associated with the app. 还可以单击“管理”来找到“Azure 资源”页 。You can also find the Azure Resources page by clicking Manage.
Your Pizza app is now ready to use.
Record the app ID, prediction key, and prediction endpoint of your Pizza app
To use your new Pizza app, you will need the app ID, prediction key, and prediction endpoint of your Pizza app.
To find these values:
- From the Intents page, select MANAGE.
- From the Application Settings page, record the App ID.
- Select Azure Resources.
- From the Azure Resources page, record the Primary Key. This value is your prediction key.
- Record the Endpoint URL. This value is your prediction endpoint.
创建 Node.js 项目Create the Node.js project
创建一个新文件夹以保存 Node.js 项目，例如
node-predict-with-rest。Create a new folder to hold your Node.js project, such asnode-predict-with-rest.打开新的命令提示符，导航到你创建的文件夹，并执行以下命令：Open a new Command Prompt, navigate to the folder you created and execute the following command:
npm init在每个提示符下按 Enter 以接受默认设置。Press Enter at each prompt to accept the default settings.
输入以下命令安装依赖项：Install the dependencies by entering the following commands:
npm install --save request npm install --save request-promise npm install --save querystring
以编程方式获取意向Get intent programmatically
使用 Node.js 查询预测终结点并获取预测结果。Use Node.js to query the prediction endpoint and get a prediction result.
- 将以下代码片段复制到名为
predict.js的文件中：Copy the following code snippet to a file namedpredict.js:
//

// YOUR-PREDICTION-ENDPOINT: Replace this with your authoring key endpoint.
// For example, "https://api.cognitive.azure.cn/"
const LUIS_endpoint = "https://YOUR-PREDICTION-ENDPOINT/";
// The utterance you want to use.
const utterance = "I want two large pepperoni pizzas on thin crust please";
//////////
// Create query string
const queryParams = {

}
// Create the URI for the REST call.
const URI = `${LUIS_endpoint}luis/prediction/v3.0/apps/${LUIS_appId}/slots/production/predict?${queryString.stringify(queryParams)}`
// Send the REST call.
const response = await requestPromise(URI);
// Display the response from the REST call.
console.log(response);
}
// Pass an utterance to the sample LUIS app
getPrediction().then(()=>console.log("done")).catch((err)=>console.log(err));
