快速入门：使用文档摘要和对话摘要
重要
对话摘要仅适用于：
- REST API
- Python
- C#
借助本快速入门，使用 .NET 客户端库创建文本摘要应用程序。 在以下示例中，你将创建一个 C# 应用程序，该应用程序可以汇总文档或基于文本的客户服务对话。
提示
可以使用 Language Studio 体验文档摘要，而无需编写代码。
先决条件
- Azure 订阅 - 创建试用订阅
- Visual Studio IDE
- 拥有 Azure 订阅后，请在 Azure 门户中创建语言资源，以获取密钥和终结点。 部署后，选择”转到资源”。
- 需要从创建的资源获取密钥和终结点，以便将应用程序连接到 API。 稍后需要在本快速入门中将密钥和终结点粘贴到代码中。
- 可以使用免费定价层 (
Free F0) 试用该服务，然后再升级到付费层进行生产。
- 若要使用“分析”功能，需要标准 (S) 定价层的“语言”资源。
设置
创建环境变量
应用程序必须经过身份验证才能发送 API 请求。 对于生产，请使用安全的方式存储和访问凭据。 在此示例中，你将凭据写入运行应用程序的本地计算机上的环境变量。
提示
请不要直接在代码中包含密钥，并且绝不公开发布密钥。 有关 Azure Key Vault 等更多身份验证选项，请参阅 Azure AI 服务安全性一文。
若要为语言资源密钥设置环境变量，请打开控制台窗口，并按照操作系统和开发环境的说明进行操作。
- 若要设置
LANGUAGE_KEY环境变量，请将your-key替换为资源的其中一个密钥。 - 若要设置
LANGUAGE_ENDPOINT环境变量，请将your-endpoint替换为资源的终结点。
setx LANGUAGE_KEY your-key
setx LANGUAGE_ENDPOINT your-endpoint
注意
如果只需要访问当前正在运行的控制台中的环境变量，则可以使用 set（而不是 setx）设置环境变量。
添加环境变量后，可能需要重启任何正在运行的、需要读取环境变量的程序（包括控制台窗口）。 例如，如果使用 Visual Studio 作为编辑器，请在运行示例之前重启 Visual Studio。
创建新的 .NET Core 应用程序
使用 Visual Studio IDE 创建新的 .NET Core 控制台应用。 这会创建包含单个 C# 源文件的“Hello World”项目：program.cs。
右键单击解决方案资源管理器中的解决方案，然后选择“管理 NuGet 包”，以便安装客户端库。 在打开的包管理器中选择“浏览”，搜索 Azure.AI.TextAnalytics。 请务必选中“包括预发行版”。 选择版本 5.3.0，然后选择“安装”。 也可使用包管理器控制台。
代码示例
将以下代码复制到 program.cs 文件。 然后运行代码。
重要
转到 Azure 门户。 如果你在“先决条件”部分创建的语言资源部署成功，请单击“后续步骤”下的“转到资源”按钮 。 可以通过导航到资源的“密钥和终结点”页，在“资源管理”下找到你的密钥和终结点。
重要
完成后，请记住将密钥从代码中删除，并且永远不要公开发布该密钥。 对于生产来说，请使用安全的方式存储和访问凭据，例如 Azure Key Vault。 有关详细信息，请参阅 Azure AI 服务安全性一文。

Windows 365 was in the works before COVID-19 sent companies around the world on a scramble to secure solutions to support employees suddenly forced to work from home, but “what really put the firecracker behind it was the pandemic, it accelerated everything,” McKelvey said. She explained that customers were asking, “’How do we create an experience for people that makes them still feel connected to the company without the physical presence of being there?”
In this new world of Windows 365, remote workers flip the lid on their laptop, bootup the family workstation or clip a keyboard onto a tablet, launch a native app or modern web browser and login to their Windows 365 account. From there, their Cloud PC appears with their background, apps, settings and content just as they left it when they last were last there - in the office, at home or a coffee shop.
“And then, when you’re done, you’re done. You won’t have any issues around security because you’re not saving anything on your device,” McKelvey said, noting that all the data is stored in the cloud.
The ability to login to a Cloud PC from anywhere on any device is part of Microsoft’s larger strategy around tailoring products such as Microsoft Teams and Microsoft 365 for the post-pandemic hybrid workforce of the future, she added. It enables employees accustomed to working from home to continue working from home; it enables companies to hire interns from halfway around the world; it allows startups to scale without requiring IT expertise.
“I think this will be interesting for those organizations who, for whatever reason, have shied away from virtualization. This is giving them an opportunity to try it in a way that their regular, everyday endpoint admin could manage,” McKelvey said.
The simplicity of Windows 365 won over Dean Wells, the corporate chief information officer for the Government of Nunavut. His team previously attempted to deploy a traditional virtual desktop infrastructure and found it inefficient and unsustainable given the limitations of low-bandwidth satellite internet and the constant need for IT staff to manage the network and infrastructure.
We didn’t run it for very long,” he said. “It didn’t turn out the way we had hoped. So, we actually had terminated the project and rolled back out to just regular PCs.”
He re-evaluated this decision after the Government of Nunavut was hit by a ransomware attack in November 2019 that took down everything from the phone system to the government’s servers. Microsoft helped rebuild the system, moving the government to Teams, SharePoint, OneDrive and Microsoft 365. Manchester’s team recruited the Government of Nunavut to pilot Windows 365. Wells was intrigued, especially by the ability to manage the elastic workforce securely and seamlessly.
“The impact that I believe we are finding, and the impact that we’re going to find going forward, is being able to access specialists from outside the territory and organizations outside the territory to come in and help us with our projects, being able to get people on staff with us to help us deliver the day-to-day expertise that we need to run the government,” he said.
“Being able to improve healthcare, being able to improve education, economic development is going to improve the quality of life in the communities.”`,

As Chief Technology Officer of Azure AI services, I have been working with a team of amazing scientists and engineers to turn this quest into a reality. In my role, I enjoy a unique perspective in viewing the relationship among three attributes of human cognition: monolingual text (X), audio or visual sensory signals, (Y) and multilingual (Z). At the intersection of all three, there’s magic—what we call XYZ-code as illustrated in Figure 1—a joint representation to create more powerful AI that can speak, hear, see, and understand humans better. We believe XYZ-code will enable us to fulfill our long-term vision: cross-domain transfer learning, spanning modalities and languages. The goal is to have pre-trained models that can jointly learn representations to support a broad range of downstream AI tasks, much in the way humans do today. Over the past five years, we have achieved human performance on benchmarks in conversational speech recognition, machine translation, conversational question answering, machine reading comprehension, and image captioning. These five breakthroughs provided us with strong signals toward our more ambitious aspiration to produce a leap in AI capabilities, achieving multi-sensory and multilingual learning that is closer in line with how humans learn and understand. I believe the joint XYZ-code is a foundational component of this aspiration, if grounded with external knowledge sources in the downstream AI tasks."

打开命令提示符窗口（例如 BASH）。
将文本编辑器中的命令粘贴到命令提示符窗口，然后运行该命令。
从响应头获取
operation-location。 值将如下 URL 所示：
https://<your-language-resource-endpoint>/language/analyze-text/jobs/12345678-1234-1234-1234-12345678?api-version=2023-04-01
- 要获取请求的结果，请使用以下 cURL 命令。 请务必将
<my-job-id>替换为从之前的operation-location响应头中收到的数值 ID 值：
curl -X GET $LANGUAGE_ENDPOINT/language/analyze-text/jobs/<my-job-id>?api-version=2023-04-01 \
-H "Content-Type: application/json" \
-H "Ocp-Apim-Subscription-Key: $LANGUAGE_KEY"
