创建一个可连接到 Azure 存储帐户的函数应用Create a function app that connects to an Azure Storage account

此 Azure Functions 示例脚本先创建一个函数应用,然后将该函数连接到 Azure 存储帐户。This Azure Functions sample script creates a function app and connects the function to an Azure Storage account. 创建的应用设置(包含连接)可以与存储触发器或绑定配合使用。The created app setting that contains the connection can be used with a storage trigger or binding.

通过此脚本创建的函数应用使用 1.x 版 Azure Functions 运行时The function app created by this script uses version 1.x of the Azure Functions runtime. 若要了解如何升级到 2.x 版,请参阅使用 Azure CLI 指定版本To learn how to upgrade to version 2.x, see Target a version using Azure CLI.

如果还没有 Azure 订阅,可以在开始前创建一个免费帐户If you don't have an Azure subscription, create a free account before you begin.

打开 Azure Cloud ShellOpen Azure Cloud Shell

Azure Cloud Shell 是一个托管在 Azure 中的交互式 shell 环境,可通过浏览器使用。Azure Cloud Shell is an interactive shell environment hosted in Azure and used through your browse. Azure Cloud Shell 允许你使用 bashPowerShell shell 运行各种工具来使用 Azure 服务。Azure Cloud Shell allows you to use either bash or PowerShell shells to run a variety of tools to work with Azure services. Azure Cloud Shell 预安装了一些命令,允许你运行本文的内容,而不必在本地环境中安装任何内容。Azure Cloud Shell comes pre-installed with the commands to allow you to run the content of this article without having to install anything on your local environment.

若要在 Azure Cloud Shell 上运行本文中包含的任何代码,请打开 Cloud Shell 会话,对代码块使用“复制” 按钮以复制代码,然后使用 Ctrl+Shift+V(在 Windows 和 Linux 上)或 Cmd+Shift+V(在 macOS 上)将其粘贴到 Cloud Shell 会话中。To run any code contained in this article on Azure Cloud Shell, open a Cloud Shell session, use the Copy button on a code block to copy the code, and paste it into the Cloud Shell session with Ctrl+Shift+V on Windows and Linux, or Cmd+Shift+V on macOS. 粘贴的文本不会自动执行,因此请按 Enter 运行代码。Pasted text is not automatically executed, so press Enter to run code.

可以通过以下方式启动 Azure Cloud Shell:You can launch Azure Cloud Shell with:

如果在本地使用 CLI,请确保运行 Azure CLI 2.0 或更高版本。If you use the CLI locally, make sure that you are running the Azure CLI version 2.0 or later. 要查找版本,请运行 az --versionTo find the version, run az --version. 如需进行安装或升级,请参阅安装 Azure CLIIf you need to install or upgrade, see Install the Azure CLI.

示例脚本Sample script

此示例创建 Azure Function app,并将存储连接字符串添加到应用设置。This sample creates an Azure Function app and adds the storage connection string to an app setting.

#!/bin/bash

# Function app and storage account names must be unique.
storageName="mystorageaccount$RANDOM"
functionAppName="myfuncwithstorage$RANDOM"

# Create a resource group with location.
az group create \
  --name myResourceGroup \
  --location westeurope

# Create a storage account in the resource group.
az storage account create \
  --name $storageName \
  --location westeurope \
  --resource-group myResourceGroup \
  --sku Standard_LRS

# Create a serverless function app in the resource group.
az functionapp create \
  --name $functionAppName \
  --resource-group myResourceGroup \
  --storage-account $storageName \
  --consumption-plan-location westeurope

# Get the storage account connection string. 
connstr=$(az storage account show-connection-string --name $storageName --resource-group myResourceGroup --query connectionString --output tsv)

# Update function app settings to connect to the storage account.
az functionapp config appsettings set \
  --name $functionAppName \
  --resource-group myResourceGroup \
  --settings StorageConStr=$connstr
