创建 Cloud DLP 去标识化模板

您可以使用模板来创建和保留配置信息以用于 Cloud Data Loss Prevention (DLP)。模板可用于将配置（如检查的内容和对内容进行去标识化的方式）与请求的实现分离。模板提供了一种可靠的方法，让您能够重复使用配置并在用户和数据集之间实现一致性。

Cloud DLP 支持两种类型的模板：

  • 去标识化模板：用于保存去标识化作业配置信息的模板，包括 infoType 和记录（结构化数据集）转换。
  • 检查模板：用于保留检查扫描作业配置信息的模板，包括要使用的预定义或自定义检测器。如需详细了解检查模板，请参阅创建 Cloud DLP 检查模板。

如需了解 Cloud DLP 中模板的相关概念，请参阅模板。

本主题的其余部分将向您介绍如何创建用于 Cloud DLP 的去标识化模板。

创建去标识化模板

值得注意的是，去标识化模板只是一种可重复使用的去标识化配置，外加一些元数据。在 API 术语中，DeidentifyTemplate 对象其实相当于包含更多元数据字段（如显示名和说明）的 DeidentifyConfig 对象。因此，要创建新的去标识化模板，基本步骤如下：

  1. 从 DeidentifyConfig 对象开始。
  2. 调用或通过 POST 发布 projects.deidentifyTemplates 资源的 create 方法，在请求中包含一个带显示名、说明和该 DeidentifyConfig 对象的 DeidentifyTemplate 对象。

返回的 DeidentifyTemplate 立即可供使用。您可以通过其 name 在其他调用或作业中引用它。您可以通过调用 *.deidentifyTemplates.list 方法列出现有模板。如需查看特定模板，请调用 *.deidentifyTemplates.get 方法。请注意，可创建的模板数量上限为 1000。

如果您曾使用 Cloud DLP 对文本、图片或结构化内容中的敏感数据进行去标识化，则说明您已创建 DeidentifyConfig 对象。再执行一步，即可将其转换为 DeidentifyTemplate 对象。

REST 示例

下面的 JSON 示例展示了您可以向 projects.deidentifyTemplates.create 方法发送哪些内容。此 JSON 会创建一个具有给定显示名和说明的新模板，并依据 infoType EMAIL_ADDRESS 和 GENERIC_ID 扫描匹配项。如果找到与这些 infoType 匹配的内容，该 JSON 将使用星号 (*) 字符遮盖前三个字符。

HTTP 方法和网址：

POST https://dlp.googleapis.com/v2/projects/PROJECT_ID/deidentifyTemplates

将 PROJECT_ID 替换为项目 ID。

JSON 输入：

{
  "deidentifyTemplate":{
    "displayName":"Email and id masker",
    "description":"De-identifies emails and ids with a series of asterisks.",
    "deidentifyConfig":{
      "infoTypeTransformations":{
        "transformations":[
          {
            "infoTypes":[
              {
                "name":"GENERIC_ID"
              }
            ],
            "primitiveTransformation":{
              "replaceWithInfoTypeConfig":{

              }
            }
          },
          {
            "infoTypes":[
              {
                "name":"EMAIL_ADDRESS"
              }
            ],
            "primitiveTransformation":{
              "characterMaskConfig":{
                "charactersToIgnore":[
                  {
                    "charactersToSkip":"@"
                  }
                ],
                "maskingCharacter":"*"
              }
            }
          }
        ]
      }
    }
  }
}

JSON 输出：

    {
      "name":"projects/PROJECT_ID/deidentifyTemplates/JOB-ID",
      "displayName":"Email and id masker",
      "description":"De-identifies emails and ids with a series of asterisks.",
      "createTime":"2018-11-30T07:17:59.536022Z",
      "updateTime":"2018-11-30T07:17:59.536022Z",
      "deidentifyConfig":{
        "infoTypeTransformations":{
          "transformations":[
            {
              "infoTypes":[
                {
                  "name":"GENERIC_ID"
                }
              ],
              "primitiveTransformation":{
                "replaceWithInfoTypeConfig":{

                }
              }
            },
            {
              "infoTypes":[
                {
                  "name":"EMAIL_ADDRESS"
                }
              ],
              "primitiveTransformation":{
                "characterMaskConfig":{
                  "maskingCharacter":"*",
                  "charactersToIgnore":[
                    {
                      "charactersToSkip":"@"
                    }
                  ]
                }
              }
            }
          ]
        }
      }
    }

如需快速尝试此操作，您可以使用下面嵌入的 APIs Explorer。 如需了解有关如何使用 JSON 将请求发送到 Cloud DLP API 的一般信息，请参阅 JSON 快速入门。

使用去标识化模板

创建新模板后，您可以在任何可接受 deidentifyTemplateName 的位置使用其 name 标识符，例如：

  • projects.content.deidentify：使用模板作为其配置，对内容中的潜在敏感数据进行去标识化。请注意，此方法可以使用检查模板或去标识化模板。

列出去标识化模板

如需列出已创建的所有去标识化模板，请使用任一 *.*.list 方法：
