Início rápido: Configurar e usar os dados do catálogo da API da Microsoft Learn Platform

Neste Quickstart, aprende a configurar e executar a Microsoft Learn Platform API, que inclui exemplos para recuperar cursos, caminhos de aprendizagem, módulos e certificações.

Pré-requisitos

Antes de começar, certifique-se de que tem instalado o seguinte:

  • Node.js (versão 18.0.0 ou superior)

    • Node.js é um runtime JavaScript que permite executar código JavaScript/TypeScript fora de um navegador web. É necessário executar os scripts de exemplo e gerir pacotes via npm (Node Package Manager).
    • Descarregar de: https://nodejs.org/
    • Verificar instalação: node --version

  • Azure CLI

    • A Interface Command-Line Azure (CLI) é uma ferramenta para gerir recursos Azure a partir da linha de comandos. Neste guia, é usado para autenticar a sua identidade, para que os exemplos possam aceder à API da Learn Platform em seu nome.
    • Descarregar de: https://docs.microsoft.com/cli/azure/install-azure-cli
    • Verificar instalação: az --version

  • Uma Conta Azure

    • É necessária uma conta Azure com uma subscrição ativa para autenticar e aceder à Microsoft Learn Platform API. A API utiliza o Microsoft Entra ID (anteriormente Azure Active Directory) para autenticação, o que requer credenciais válidas do Azure. Não há custo para recuperar o token de autenticação da sua subscrição Azure.
    • Precisa de uma subscrição ativa do Azure
    • Inscreva-se em: https://azure.microsoft.com/free/

  • Visual Studio Code (opcional)

    • O Visual Studio Code (VS code) é um editor de código gratuito e leve, com terminal integrado, suporte a IntelliSense e TypeScript. Embora possa usar qualquer editor de texto e terminal, o Visual Studio Code oferece uma experiência simplificada para executar estes exemplos.
    • Descarregar de: https://code.visualstudio.com/
    • Verificar instalação: Abra o Visual Studio Code e pressione Ctrl+' para abrir o terminal integrado

Observação

Todos os comandos escritos abaixo devem ser executados num terminal Git Bash. Pode usar o terminal integrado do VS Code (pressione Ctrl+'), o PowerShell do Windows ou o Prompt de Comandos.

Configurar o projeto

Siga estes passos para criar um novo projeto e instalar as dependências necessárias.

  1. Cria uma nova pasta para o teu projeto e navega até ela.

    mkdir learn-api-examples
cd learn-api-examples

  2. Inicialize um novo projeto Node.js com as definições predefinidas. A -y flag aceita automaticamente todos os defaults.

    npm init -y

  3. Instale os pacotes npm necessários (@azure/identity para autenticação, tsx para executar TypeScript diretamente, typescript compilador e @types/node para definições de tipo).

    npm install @azure/identity tsx typescript @types/node

  4. Crie um novo ficheiro chamado examples.ts e cole o código abaixo. Isto inclui autenticação utilizando Azure Default Credentials e vários exemplos das capacidades do catálogo disponíveis através da API Learn Platform.

Autenticar e executar os exemplos

Siga estes passos para autenticar com o Azure e executar o código de exemplo.

  1. Entre na CLI do Azure. Este passo abre uma janela do navegador onde introduz as suas credenciais Azure.

    az login

  2. Se tiveres várias subscrições, define a ativa. Substitua <your-subscription-name> pelo nome ou ID da subscrição.

    az account set --subscription "<your-subscription-name>"

  3. Verifique se as suas credenciais podem aceder à API da Learn Platform.

    az account get-access-token --resource https://learn.microsoft.com

    Se for bem-sucedido, verá uma resposta JSON com o campo accessToken.

  4. Execute o ficheiro de exemplos utilizando npx para executar o pacote tsx.

    npx tsx examples.ts

  5. (Opcional) Guarde a saída num ficheiro usando redirecionamento de saída.

    npx tsx examples.ts > output.txt 2>&1

Limpeza de recursos

Se já não precisares dos recursos criados neste quickstart, podes removê-los.

  1. Remove a pasta do projeto e todo o seu conteúdo.

    cd ..
rm -rf learn-api-examples

    No PowerShell do Windows, utilize:

    cd ..
Remove-Item -Recurse -Force learn-api-examples

  2. (Opcional) Sair do Azure CLI para remover credenciais em cache.

    az logout

Observação

Este quickstart não cria recursos Azure que gerem custos. As chamadas à API usam a sua identidade Azure existente apenas para autenticação.
