[FunctionName("GetDetails")]
public async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "v1/{Id}/details")] HttpRequest request, int Id)
{
    //my code here to get claims from the User context (request.HttpContext.User).
}

我还尝试在我的函数中注入 ClaimsPrincipal 对象，如下所示：

[FunctionName("GetDetails")]
public async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "v1/{Id}/details")] HttpRequest request, int Id, **ClaimsPrincipal principal**)
{
    //my code here to get claims from the User context (request.HttpContext.User).
}

结果还是一样。为了在本地访问该功能，我将传递我的 Bearer 访问令牌，如下所示：授权：Bearer

任何想法我在这里想念什么？

根据我的测试，使用request.HttpContext.User可以获取受AADin保护的函数的认证信息Azure portal。

不明白你为什么在Bearer本地通过，但是如果你有这个需求，可以参考以下代码：</p> 

            req.Headers.TryGetValue("Authorization", out var headers);

            var authorization = headers.First();

            var jwt = authorization.Split(' ')[1];
            var handler = new JwtSecurityTokenHandler();
            var token = handler.ReadJwtToken(jwt);
            var unique_name = token.Claims.First(claim => claim.Type == "unique_name").Value;
            log.LogInformation(unique_name);

您可以参考Decode JWTs in C# for Authorization。

笔记：

如果遇到这个错误：</p> 

System.Private.CoreLib: Exception while executing function: Function1. FunctionPa: Could not load file or assembly 'System.IdentityModel.Tokens.Jwt, Version=6.8.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

您可以<_FunctionsSkipCleanOutput>true</_FunctionsSkipCleanOutput>在csproj文件中添加：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <AzureFunctionsVersion>v3</AzureFunctionsVersion>
      <_FunctionsSkipCleanOutput>true</_FunctionsSkipCleanOutput>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.11" />
    <PackageReference Include="System.IdentityModel.Tokens.Jwt" Version="6.8.0" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
