解决方案

如果您的 azure 函数身份验证级别是匿名的或还需要函数密钥，我们可以使用访问令牌直接访问您的 Azure 函数 API.详细步骤如下.

1. 为 Azure Function 配置 Azure AD.请参考

   然后我可以直接使用访问令牌.我用 Postman 测试过:

   请注意，如果你的天蓝色函数认证级别不是匿名的，你需要添加函数密钥

   解决方案

   We could use the access token to access your Azure function API directly if your azure function authentication level is anonymous or function key is also required. The detailed steps are as below.

   1. Configure Azure AD for Azure Function. Please refer to https://docs.microsoft.com/en-us/azure/azure-functions/functions-how-to-use-azure-function-app-settings#auth.
   2. Get Access token

   I get an access token from AAD using clientID and clientSecret using the following code:

   METHOD: POST
   
   Url : https://login.microsoftonline.com/your directory ID/oauth2/token 
   
   HEADERS:  Content-Type : application/x-www-form-urlencoded
   
   BODY: grant_type+=client_credentials&resource+="your Function url"&client_id+++++="the application that your register  id"&client_secret+="the key you create"
   

   Please note that according to the Azure Resources portal (https://resources.azure.com/), the default allowedAudiences is

   https://{functionAppName}.azurewebsites.net/.auth/login/aad/callback
   

   So I added the https://{functionAppName}.azurewebsites.net/ as allowed audiences.

   Then I can use the access token directly. I tested it with Postman:

   Please note that if your azure function authentication level is not anonymous, you need to add the function key
