快速入门：使用 curl 和 PowerShell 存储医疗保健数据

使用 curl 和 PowerShell 存储医疗保健数据

本页面介绍了如何使用 Cloud Healthcare API 和 curl 或 Windows PowerShell 来完成以下任务：

  1. 创建 Cloud Healthcare API 数据集。
  2. 在数据集内创建以下数据存储区之一：
    • 医学数字图像和通信 (DICOM) 存储区
    • 快速医疗互操作性资源 (FHIR) 存储区
    • Health Level Seven International 版本 2 (HL7v2) 存储区
  3. 在 DICOM、FHIR 或 HL7v2 存储区中存储和检查特定类型的医疗数据。

如果您只想使用一种数据存储区，则可在完成准备工作以及创建数据集中的步骤后，直接跳到快速入门的相应部分。

准备工作

  1. 登录您的 Google Cloud 帐号。如果您是 Google Cloud 新手，请创建一个帐号来评估我们的产品在实际场景中的表现。新客户还可获享 $300 赠金，用于运行、测试和部署工作负载。

  2. 在 Google Cloud Console 中的项目选择器页面上，选择或创建一个 Google Cloud 项目。

    转到“项目选择器”

  3. 确保您的 Cloud 项目已启用结算功能。了解如何检查项目是否已启用结算功能。

  4. 启用 Cloud Healthcare API。

    8.
  8. 安装并初始化 Google Cloud CLI。
  9. 使用 Google Cloud CLI 测试您的身份验证环境。检查以下命令是否输出无错误的文本字符串：
    gcloud auth application-default print-access-token

提示：需要命令提示符？您可以使用 Google Cloud Shell。Cloud Shell 命令行环境已经包含 Google Cloud CLI，因此您无需再进行安装。（Compute Engine 虚拟机也预装了 Google Cloud CLI。）

创建数据集

数据集包含数据存储区，数据存储区包含医疗保健数据。 要使用 Cloud Healthcare API，您必须至少创建一个数据集。

使用 datasets.create 方法创建数据集：

curl

curl -X POST \
    --data "" \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets?datasetId=my-dataset"

将 PROJECT_ID 替换为您在准备工作中创建或选择的 Google Cloud 项目的 ID。

响应如下所示。响应包含长时间运行的操作的标识符。当方法调用可能需要大量时间才能完成时，会返回长时间运行的操作。

{
  "name": "projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/operations/OPERATION_ID",
}

在此输出中：

  • PROJECT_ID、us-central1、my-dataset：您在方法调用中提供的值
  • OPERATION_ID：Cloud Healthcare API 提供的长时间运行的操作的标识符

要跟踪操作的状态，请使用 operations.get 方法：

curl -X GET \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/operations/OPERATION_ID"

替换以下内容：

  • PROJECT_ID：您的 Google Cloud 项目的 ID
  • OPERATION_ID：从长时间运行的操作返回的 ID

输出如下所示。如果响应包含 "done": true，则表示操作已完成。否则表示操作仍在运行；请等待几秒钟，然后再次调用 operations.get 方法。

{
  "name": "projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.healthcare.v1.OperationMetadata",

    "@type": "type.googleapis.com/google.cloud.healthcare.v1.dataset.Dataset",
    "name": "projects/PROJECT_ID/locations/us-central1/datasets/my-dataset"
  }
}

PowerShell

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

Invoke-WebRequest `
  -Method Post `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets?datasetId=my-dataset" | Select-Object -Expand Content

现在，您已在 Cloud Healthcare API 中存储和查看了 DICOM 实例，接下来请执行清理操作，以避免因本页中使用的资源导致您的 Google Cloud 帐号产生费用。

如需详细了解如何使用 DICOM 数据，请参阅后续步骤。

存储和查看 FHIR 资源

本部分介绍了如何完成以下任务：

  1. 创建 FHIR 存储区。
  2. 在 FHIR 存储区中存储 FHIR 资源。
  3. 查看 FHIR 资源的数据。

Cloud Healthcare API 实现了 FHIR 规范标准，用于存储和访问 FHIR 数据。

创建 FHIR 存储区

FHIR 存储区位于数据集内，用于存储 FHIR 资源。使用 fhirStores.create 方法创建 FHIR 存储区：

curl

curl -X POST \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    --data "{
      'version': 'R4'
    }" "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/fhirStores?fhirStoreId=my-fhir-store"

将 PROJECT_ID 替换为您在准备工作中创建或选择的 Google Cloud 项目的 ID。

现在，您已在 Cloud Healthcare API 中存储和查看了 FHIR 资源，接下来请执行清理操作，以避免因本页中使用的资源导致您的 Google Cloud 帐号产生费用。

如需详细了解如何使用 FHIR 数据，请参阅后续步骤。

存储和查看 HL7v2 消息

本部分介绍了如何完成以下任务：

  1. 创建 HL7v2 存储区
  2. 将 HL7v2 消息存储在 HL7v2 存储区中。
  3. 查看 HL7v2 消息的数据。

Cloud Healthcare API 中的 HL7v2 实现符合 HL7v2 标准。

创建 HL7v2 存储区

HL7v2 存储区位于数据集内，用于存储 HL7v2 数据。使用 hl7V2Stores.create 方法创建 HL7v2 存储区：

curl

curl -X POST \
    --data "" \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/hl7V2Stores?hl7V2StoreId=my-hl7v2-store"

将 PROJECT_ID 替换为您在准备工作中创建或选择的 Google Cloud 项目的 ID。

输出如下所示：

{
  "name": "projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/hl7V2Stores/my-hl7v2-store"
}

PowerShell

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

Invoke-WebRequest `
  -Method Post `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/hl7V2Stores?hl7V2StoreId=my-hl7v2-store" | Select-Object -Expand Content

将 PROJECT_ID 替换为您在准备工作中创建或选择的 Google Cloud 项目的 ID。

输出如下所示：

{
  "name": "projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/hl7V2Stores/my-hl7v2-store"
}

创建 HL7v2 消息

  1. 将示例 HL7v2 消息文件下载到您的机器上：

    curl

    curl -O https://cloud.google.com/healthcare-api/docs/resources/hl7v2-sample.json

    PowerShell

    Invoke-WebRequest -Uri "https://cloud.google.com/healthcare-api/docs/resources/hl7v2-sample.json" -OutFile $pwd/hl7v2-sample.json

    HL7v2 消息包含以下基本信息，它采用 base-64 编码存放在示例文件的 data 字段中：

    MSH|^~\&|A|SEND_FACILITY|A|A|20180101000000||TYPE^A|20180101000000|T|0.0|||AA||00|ASCII
EVN|A00|20180101040000
PID||14^111^^^^MRN|11111111^^^^MRN~1111111111^^^^ORGNMBR

  2. 使用 messages.create 方法存储 HL7v2 消息。本快速入门假定您从下载 HL7v2 消息文件所在的目录中运行该命令。

    curl

    curl -X POST \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     --data-binary @hl7v2-sample.json \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets/my-dataset/hl7V2Stores/my-hl7v2-store/messages"

    将 PROJECT_ID 替换为您在准备工作中创建或选择的 Google Cloud 项目的 ID。

    输出如下所示：

现在，您已在 Cloud Healthcare API 中存储和查看了 HL7v2 消息，接下来请执行清理操作，以避免因本页中使用的资源导致您的 Google Cloud 帐号产生费用。

如需详细了解如何使用 HL7v2 数据，请参阅后续步骤。

清理

为避免因本页中使用的资源导致您的 Google Cloud 帐号产生费用，请按照以下步骤操作。

如果您为此快速入门创建了新项目，请按照删除项目中的步骤操作。否则，请按照删除数据集中的步骤操作。

删除项目

  1. 在 Google Cloud 控制台中，转到管理资源页面：

    转到“管理资源”

  2. 在项目列表中，选择要删除的项目，然后点击删除。
  3. 在对话框中输入项目 ID，然后点击关闭以删除项目。

删除数据集

如果您不再需要在本快速入门中创建的数据集，可以将其删除。删除数据集会永久删除该数据集以及其中包含的任何 FHIR、HL7v2 或 DICOM 存储区。

     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets/my-dataset"

将 PROJECT_ID 替换为您在准备工作中创建或选择的 Google Cloud 项目的 ID。

输出如下所示：

{}

PowerShell

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

Invoke-WebRequest `
  -Method Delete `
  -Headers $headers `
  -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/us-central1/datasets/my-dataset" | Select-Object -Expand Content
