若要了解 LUIS 预测终结点返回的内容，请在 Web 浏览器中查看预测结果。To understand what a LUIS prediction endpoint returns, view a prediction result in a web browser.

先决条件Prerequisites

若要查询公共应用，需要：In order to query a public app, you need:

• 自己的语言理解 (LUIS) 密钥。Your own Language Understanding (LUIS) key. 如果你没有用于创建密钥的订阅，可以注册一个试用帐户。If you do not already have a subscription to create a key, you can register for a trial account. 无法使用 LUIS 创作密钥。The LUIS authoring key will not work.
• 公共应用的 ID：df67dcdb-c37d-46af-88e1-8b97951ca1c2。The public app's ID: df67dcdb-c37d-46af-88e1-8b97951ca1c2.

使用浏览器查看预测Use the browser to see predictions

1. 打开 Web 浏览器。Open a web browser.

2. 使用以下完整 URL（请将 YOUR-KEY 替换为自己的 LUIS 密钥）。Use the complete URLs below, replacing YOUR-KEY with your own LUIS key. 请求为 GET 请求，并包含授权和 LUIS 密钥作为查询字符串参数。The requests are GET requests and include the authorization, with your LUIS key, as a query string parameter.

   • V3 预测请求V3 prediction request
   • V2 预测请求V2 prediction request

   GET 终结点（按槽）请求的 V3 URL 格式为：The format of the V3 URL for a GET endpoint (by slots) request is:

   https://{region}.api.cognitive.azure.cn/luis/prediction/v3.0/apps/df67dcdb-c37d-46af-88e1-8b97951ca1c2/slots/production/predict?query=turn on all lights&subscription-key=YOUR-KEY

3. 将该 URL 粘贴到浏览器窗口中，然后按 Enter。Paste the URL into a browser window and press Enter. 浏览器显示的 JSON 结果指示 LUIS 将 HomeAutomation.TurnOn 意向检测为首要意向，并检测到值为 on 的 HomeAutomation.Operation 实体。The browser displays a JSON result that indicates that LUIS detects the HomeAutomation.TurnOn intent as the top intent and the HomeAutomation.Operation entity with the value on.

   • V2 预测响应V2 prediction response

   {
       "query": "turn on all lights",
       "prediction": {
           "topIntent": "HomeAutomation.TurnOn",
           "intents": {
               "HomeAutomation.TurnOn": {
                   "score": 0.5375382
               }
           },
           "entities": {
               "HomeAutomation.Operation": [
                   "on"
               ]
           }
       }
   }
   

4. 要查看所有意图，请添加相应的查询字符串参数。To see all the intents, add the appropriate query string parameter.

   • V3 预测终结点V3 prediction endpoint
   • V2 预测终结点V2 prediction endpoint

   将 show-all-intents=true 添加到查询字符串末尾可显示所有意向：Add show-all-intents=true to the end of the querystring to show all intents:

   https://{region}.api.cognitive.azure.cn/luis/predict/v3.0/apps/df67dcdb-c37d-46af-88e1-8b97951ca1c2/slots/production/predict?query=turn on all lights&subscription-key=YOUR-KEY&show-all-intents=true

   {
       "query": "turn off the living room light",
       "prediction": {
           "topIntent": "HomeAutomation.TurnOn",
           "intents": {
               "HomeAutomation.TurnOn": {
                   "score": 0.5375382
               },
               "None": {
                   "score": 0.08687421
               },
               "HomeAutomation.TurnOff": {
                   "score": 0.0207554
               }
           },
           "entities": {
               "HomeAutomation.Operation": [
                   "on"
               ]
           }
       }
   }
