使用 FieldMask 更新数据

使用 API 更新代理数据时，您可以选择覆盖整个数据类型或仅覆盖数据类型的特定字段。通常情况下，最好覆盖特定字段，以免因意外覆盖所有数据。如要覆盖特定字段，请为更新请求提供 FieldMask。

以下示例展示了如何提供 FieldMask 以更新 Intent 类型的显示名。

为意图参考选择协议和版本：

协议	V3	V3beta1
REST	意图资源	意图资源
RPC	intent 接口	intent 接口
C++	IntentsClient	不可用
C#	IntentsClient	不可用
Go	IntentsClient	不可用
Java	IntentsClient	IntentsClient
Node.js	IntentsClient	IntentsClient
PHP	不可用	不可用
Python	IntentsClient	IntentsClient
Ruby	不可用	不可用

REST 和命令行

在使用任何请求数据之前，请先进行以下替换：

PROJECT_ID：您的 GCP 项目 ID
AGENT_ID：您的代理 ID
REGION_ID：您的区域 ID
INTENT_ID：您的意图 ID
DISPLAY_NAME：所需的显示名

HTTP 方法和网址：

PATCH https://REGION_ID-dialogflow.googleapis.com/v3/projects/PROJECT_ID/locations/REGION_ID/agents/AGENT_ID/intents/INTENT_ID?updateMask=displayName

请求 JSON 正文：

{
  "displayName": "DISPLAY_NAME"
}

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

curl -X PATCH \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://REGION_ID-dialogflow.googleapis.com/v3/projects/PROJECT_ID/locations/REGION_ID/agents/AGENT_ID/intents/INTENT_ID?updateMask=displayName"

PowerShell (Windows)

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method PATCH `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -InFile request.json `
  -Uri "https://REGION_ID-dialogflow.googleapis.com/v3/projects/PROJECT_ID/locations/REGION_ID/agents/AGENT_ID/intents/INTENT_ID?updateMask=displayName" | Select-Object -Expand Content

您应该会收到类似以下内容的 JSON 响应：

{
  "name": "projects/your-project-id/locations/us-central1/agents/c2a370ca-158a-4296-a211-d5ab6bb84324/intents/91aa7827-d69b-4077-8b21-7a66b8b59f16",
  "displayName": "your-display-name",
  ...
}
