HTTP Error 500.30 Azure.RequestFailedException

Question

我使用Visual Studio 4.8.04084将我的应用程序推送到Azure应用程序服务。我已经为配置了连接

• Azure应用程序配置
• Azure密钥保管库
• Azure SQL数据库：我的数据
• Azure SQL数据库：身份服务
• Azure存储
• Secrets.json

当我在本地通过Kestrel服务运行应用程序时，一切都很好。然而，当我通过IIS运行它时，我会遇到以下问题：

Visual Studio异常消息：

引发异常：Microsoft.Extension.Configuration.AzureAppConfiguration.dll 中的"Azure.RequestFailedException">

引发异常：Navrae.WebApp.dll 中的"Azure.RequestFailedException">

Navrae.WebApp.dll中发生类型为"Azure.RequestFailedException"的异常，但未在用户代码中进行处理

Azure日志链接消息*

{"error":{"code":"AuthenticationFailed","message":"Authentication failed. The 'Authorization' header is missing."}}

当我调试应用程序时，它基本上在CreateHostBuilder中失败。我的ConnectionStrings都没有填充，我不知道在哪里或如何进一步调试它。

CreateHostBuilder

public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((context, config) =>
{
var azConfigSettings = config.Build();
var azConfigConnection = azConfigSettings.GetConnectionString("REMOVED");
if (!string.IsNullOrEmpty(azConfigConnection))
{
// Use the connection string if it is available.
config.AddAzureAppConfiguration(azConfigConnection);
}
else if (Uri.TryCreate(azConfigSettings["Endpoints:REMOVED"], UriKind.Absolute, out var endpoint))
{
// Use Azure Active Directory authentication.
config.AddAzureAppConfiguration(options =>
{
options.Connect(endpoint, new DefaultAzureCredential());
});
}
var keyVaultEndpoint = new Uri(Environment.GetEnvironmentVariable("REMOVED")!);
config.AddAzureKeyVault(
keyVaultEndpoint,
new DefaultAzureCredential());
})
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});

Answer 1

您得到的错误是HTTP 403 Forbidden。

可能发生的情况是：

• 当您在本地运行时，您使用的是可以访问Azure服务的身份
• 当您在IIS中运行时，您使用的是无法访问Azure服务的网络服务标识

在Azure应用程序服务中，您可以将其配置为以"；"管理身份"；，然后，您可以授予该托管身份对您正在使用的服务的访问权限。
