若要在 Azure 逻辑应用中的企业集成方案格式之间传输 XML 数据，逻辑应用可以使用映射，或者更具体地说，使用可扩展样式表语言转换 (XSLT) 映射。To transfer XML data between formats for enterprise integration scenarios in Azure Logic Apps, your logic app can use maps, or more specifically, Extensible Style sheet Language Transformations (XSLT) maps. 映射是一个 XML 文档，描述如何将 XML 文档中的数据转换为另一种格式。A map is an XML document that describes how to convert data from an XML document into another format.

例如，假设你从使用 YYYMMDD 日期格式的客户定期接收 B2B 订单或发票。For example, suppose you regularly receive B2B orders or invoices from a customer who uses the YYYMMDD date format. 但是，你的组织使用 MMDDYYY 日期格式。However, your organization uses the MMDDYYY date format. 在将订单或发票详细信息存储在客户活动数据库中之前，可以定义并使用一个映射将 YYYMMDD 日期格式转换为 MMDDYYY 格式。You can define and use a map that transforms the YYYMMDD date format to the MMDDYYY format before storing the order or invoice details in your customer activity database.

有关集成帐户和映射等项目的限制，请参阅 Azure 逻辑应用的限制和配置信息。For limits related to integration accounts and artifacts such as maps, see Limits and configuration information for Azure Logic Apps.

先决条件Prerequisites

• Azure 订阅。An Azure subscription. 如果没有 Azure 订阅，请注册试用版订阅。If you don't have a subscription, sign up for a Trial Subscription.

• 一个集成帐户，用于存储映射以及企业集成与企业到企业 (B2B) 解决方案的其他项目。An integration account where you store your maps and other artifacts for enterprise integration and business-to-business (B2B) solutions.

• 如果映射引用了外部程序集，必须将该程序集和映射上传到集成帐户。 If your map references an external assembly, you have to upload both the assembly and the map to your integration account. 请务必先上传程序集，然后再上传引用程序集的映射。 Make sure you upload your assembly first, and then upload the map that references the assembly.

  如果程序集为 2 MB 或更小，可以直接从 Azure 门户将程序集添加到集成帐户。 If your assembly is 2 MB or smaller, you can add your assembly to your integration account directly from the Azure portal. 但是，如果程序集或映射大于 2 MB 但不超过程序集或映射的大小限制，则可以使用以下选项：However, if your assembly or map is bigger than 2 MB but not bigger than the size limit for assemblies or maps, you have these options:

  • 对于程序集，需要一个可在其中上传程序集的 Azure Blob 容器，并规划好该容器的位置。For assemblies, you need an Azure blob container where you can upload your assembly and that container's location. 这样，在将程序集添加到集成帐户时，便可以提供该位置。That way, you can provide that location later when you add the assembly to your integration account. 对于此任务，需要提供以下各项：For this task, you need these items:

    项目Item	说明Description
    Azure 存储帐户Azure storage account	在此帐户中创建程序集的 Azure Blob 容器。In this account, create an Azure blob container for your assembly. 了解如何创建存储帐户。Learn how to create a storage account.
    Blob 容器Blob container	可在此容器中上传程序集。In this container, you can upload your assembly. 将程序集添加到集成帐户时，也需要此容器的位置。You also need this container's location when you add the assembly to your integration account. 了解如何创建 Blob 容器。Learn how to create a blob container.
    Azure 存储资源管理器Azure Storage Explorer	借助此工具可以更轻松地管理存储帐户和 Blob 容器。This tool helps you more easily manage storage accounts and blob containers. 若要使用存储资源管理器，请下载并安装 Azure 存储资源管理器。To use Storage Explorer, either download and install Azure Storage Explorer. 然后，遵循存储资源管理器入门中的步骤将存储资源管理器连接到存储帐户。Then, connect Storage Explorer to your storage account by following the steps in Get started with Storage Explorer. 若要了解详细信息，请参阅快速入门：使用 Azure 存储资源管理器在对象存储中创建 Blob。To learn more, see Quickstart: Create a blob in object storage with Azure Storage Explorer. 或者，在 Azure 门户中找到并选择你的存储帐户。Or, in the Azure portal, find and select your storage account. 在存储帐户菜单中选择“存储资源管理器”。 From your storage account menu, select Storage Explorer.

  • 对于映射，目前可以使用 Azure 逻辑应用 REST API - 映射添加较大的映射。For maps, you can currently add larger maps by using the Azure Logic Apps REST API - Maps.

创建和添加映射时不需要逻辑应用。You don't need a logic app when creating and adding maps. 但是，若要使用映射，逻辑应用需要链接到存储该映射的集成帐户。However, to use a map, your logic app needs linking to an integration account where you store that map. 了解如何将逻辑应用链接到集成帐户。Learn how to link logic apps to integration accounts. 如果没有逻辑应用，请了解如何创建逻辑应用。If you don't have a logic app yet, learn how to create logic apps.
