Startup.Auth.cs 不接受环境变量

Question

这是所有感兴趣的人的完整来源： https://github.com/josephmcasey/me/blob/master/JosephMCasey/App_Start/Startup.Auth.cs

我正在使用带有 C# 的 ASP.Net 构建个人网站组合。目前我收到以下错误，我知道这些错误与我的 Startup.Auth.cs 类文件有关。

    [ArgumentException: The 'ClientId' option must be provided.]
    Microsoft.Owin.Security.Google.GoogleOAuth2AuthenticationMiddleware..ctor(OwinMiddleware next, IAppBuilder app, GoogleOAuth2AuthenticationOptions options) +280
   lambda_method(Closure , OwinMiddleware , IAppBuilder , GoogleOAuth2AuthenticationOptions ) +83
    [TargetInvocationException: Exception has been thrown by the target of an invocation.]
    [HttpException (0x80004005): Exception has been thrown by the target of an invocation.]

如何在不手动将它们键入源代码的情况下从 azure 应用程序的设置中正确调用这些客户端密码字符串？

        app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
        {
            ClientId = Environment.GetEnvironmentVariable("APPSETTING_Google-clientId"),
            ClientSecret = Environment.GetEnvironmentVariable("APPSETTING_Google-clientSecret")
        });

Answer 1

要详细说明接受的答案，这并不能解释问题 - 您的开发者客户端 ID 需要作为中间件身份验证设置的一部分添加。

（我在使用 Facebook 身份验证时遇到了同样的问题，刚刚意识到我在使用新机器时忘记设置密钥）。

根据接受的配置使用答案，提醒不要对密钥进行硬编码，因此请使用 CloudConfigurationManager，或通过 使用 ASP.Net6“用户密码”存储>Microsoft.Extensions.SecretManager.

使用机密管理器的一个很好的演练是： http://docs.asp.net/en/latest/security/authentication/sociallogins.html
