Question

我的项目中有以下功能：

[FunctionName("my-func")]
public static async Task Run([BlobTrigger("data/{name}")] CloudBlockBlob blob, string name, TraceWriter log)
{
    log.Info($"Started Processing: {name}");

    await blob.DeleteAsync();

    log.Info($"Finished Processing: {name}");
}

当我尝试使用Azure Functions CLI的v1.0.4在本地运行该函数时，出现此错误：

Microsoft.Azure.WebJobs.Host: Error indexing method 'SampleFunction.Run'. Microsoft.Azure.WebJobs.Host: Can't bind BlobTrigger to type 'Microsoft.WindowsAzure.Storage.Blob.CloudBlockBlob'.

我在Azure Functions和WebJobs SDK上看到的所有文档都说支持这一点。

Answer 1

您可能正在引用一些依赖于WindowsAzure.Storage程序集的不兼容版本（版本8.x.x）的NuGet包。如果是这样，请务必将其删除。除非您使用其他绑定，否则csproj引用应该看起来像这样简单：

<ItemGroup>           
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.6" />
</ItemGroup>

确保您运行的是Azure存储模拟器：

cd C:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator

C:\Program Files (x86)\Microsoft SDKs\Azure\Storage Emulator> AzureStorageEmulator.exe start
Windows Azure Storage Emulator 5.2.0.0 command line tool

如何在Azure函数中使用BlobTrigger绑定到CloudBlockBlob？
