尝试向Azure管理SDK进行身份验证时发生异常

问题描述

在v1或v2 azure函数应用程序中尝试使用.net管理SDK(Microsoft.Azure.Management.Fluent)对我的Azure帐户进行身份验证时，出现以下异常:

I am getting the following exception while trying to authenticate to my azure account using the .net management SDK (Microsoft.Azure.Management.Fluent) in a v1 or v2 azure functions app:

Full Exception : Exception while executing function: status 
 System.ArrayTypeMismatchException : Attempted to access an element as a type incompatible with the array.
   at System.Collections.Generic.List`1.Add(T item)

   at async Microsoft.Azure.WebJobs.Host.Executors.FunctionExecutor.ExecuteWithLoggingAsync(??)
   at async Microsoft.Azure.WebJobs.Host.Executors.FunctionExecutor.ExecuteWithLoggingAsync(??) 
   End of inner exception

引起异常的代码如下:

AzureCredentials credentials = SdkContext.AzureCredentialsFactory.FromServicePrincipal(AzureManagementData.CLIENTID, AzureManagementData.SECRET, AzureManagementData.DOMAIN, AzureEnvironment.AzureGlobalCloud);

Azure.IConfigurable azure = .configure();

Azure.IConfigurable azure = Azure.Configure();

azure = azure.WithLogLevel(HttpLoggingDelegatingHandler.Level.BodyAndHeaders);

azure = azure.WithLogLevel(HttpLoggingDelegatingHandler.Level.BodyAndHeaders);

Azure.IAuthenticated authenticated = azure.Authenticate(credentials);  //这里发生异常

Azure.IAuthenticated authenticated = azure.Authenticate(credentials);  // exception occurs here

IAzure authenticated2 = authenticated.WithDefaultSubscription();

IAzure authenticated2 = authenticated.WithDefaultSubscription();

有人知道，是什么导致此异常?我已经看过是否可以自己解决这个问题，但是没有找到有关此异常的任何有用信息.

Does anyone know, what is causing this exception? I Looked already if I can solve this on my own, but didn't find any helpful information about this exception.

当我在普通控制台应用程序中运行此异常时，不会发生此异常.

This exception does not occur, when I run this in a normal console application.

推荐答案

从那以后，我认为您正面临与此SO 线程.

And from that, I think you are facing the same issue as mentioned in this SO thread.

您可以尝试在.csproj文件中指定Newtonsoft.Json的特定版本(我认为应该尝试最新版本)，然后重试吗?

Could you try specifying a specific version of Newtonsoft.Json (I think trying the latest should do) in your .csproj file and try again?
