Azure Function Nuget 缓存还原失败，错误代码为 "The user name or password is incorrect."

Question

我有一个作为 ARM 模板的一部分部署的 Azure 函数。此 Azure 函数引用了一些外部 .NET DLL。我已在 project.json 文件中添加了对这些 DLL 的引用:

项目.json:

{
    "frameworks": {
        "net46": {
            "dependencies": {
                "Microsoft.IdentityModel.Clients.ActiveDirectory":"3.13.8",
                "Newtonsoft.Json":  "10.0.2",
                 "Microsoft.CrmSdk.CoreAssemblies" : "8.2.0.2" 
            }
        }
    }
 }

当我单击“运行”时，Nuget 缓存恢复将启动。它失败并显示“用户名或密码不正确。”

奇怪的是 Nuget 包已正确复制到 Functions Nuget 缓存，但无法创建 project.lock.json 文件。 Nuget 缓存还原完成后以及 Azure 尝试写入 project.lock.json 文件时，似乎会引发用户名/密码错误。然后编译失败，因为未创建 project.lock.json 文件。

有谁知道为什么会显示此错误？对我来说似乎是断断续续的。似乎是 Azure Functions 中的错误。有任何已知的解决方法吗？

我发现在 Azure Functions 上启用“插槽”预览功能实际上可以解决此问题，但“插槽”对我不起作用，因为它们与 Azure 逻辑应用不兼容。

Answer 1

看来 Microsoft 已确认这是 Azure Functions 中的错误 https://github.com/Azure/Azure-Functions/issues/590

我知道的唯一解决方法是:

• 启用插槽功能
• 不断重新部署您的 ARM 模板，直至其正常工作
• (我没有验证这一点)但我怀疑如果您手动生成锁定文件并将其删除到 Functions 文件系统，它会起作用。您可以使用 Visual Studio 在本地生成锁定文件。我怀疑这会起作用，因为根据我的观察，NuGet 包似乎已正确恢复，并且在写入 JSON 文件期间出现错误。编译器在尝试编译时必须引用锁定文件而不是实际的 NuGet 缓存(这就是为什么即使 DLL 实际存在也会出现错误)。
