如何通过Azure webapps-deploy GitHub Action设置Git提交SHA为环境变量

要将当前GitHub提交的SHA值设置为Azure Web App的环境变量，你可以直接利用GitHub Actions内置的github.sha上下文获取完整提交哈希，然后通过azure/webapps-deploy动作的app-settings参数完成配置。以下是针对你现有YAML流水线的修改方案：

修改核心逻辑 #

在deploy-staging和deploy-production的部署步骤中，添加app-settings参数注入环境变量即可，不需要额外复杂操作：

# 部署步骤中新增的配置
app-settings: |
  GIT_COMMIT_SHA=${{ github.sha }}

          # 新增：设置提交SHA为环境变量
          app-settings: |
            GIT_COMMIT_SHA=${{ github.sha }}

补充说明 #

• 如果需要短SHA（前7位），可以将${{ github.sha }}改为${{ github.sha }}[:7]
• 配置的GIT_COMMIT_SHA会直接同步到Azure Web App的应用设置中，部署完成后可在Azure门户查看，也能在应用代码中直接读取该环境变量
