Azure 功能的文件存储在哪里?

问题描述

我有通过 C# 代码从内部引用的文件，例如:

I have files that I reference from inside by C# code such as:

public static string Canonical()
{
    return File.ReadAllText(@"C:\myapp\" + "CanonicalMessage.xml");
}

如何从 Azure 函数中引用此文件?

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
    var data = File.ReadAllText(@"c:\myapp\" + "CanonicalMessage.xml");

    //etc
}

也许我可以简单地将这个资源嵌入到项目中?

推荐答案

是的，将文件放在Azure Function项目的根目录下，并将其属性Copy to Output Directory设置为Copy if较新的.使用下面的代码.

Yes, put the file at the root of Azure Function project and set its property Copy to Output Directory to Copy if newer. Use code below.

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log, ExecutionContext context)
{
    var data = File.ReadAllText(context.FunctionAppDirectory+"/CanonicalMessage.xml");

    //etc
}

检查 文档 了解更多详情.

Check the doc for more details.

如果我们需要从本地任何地方添加此文件，请右键单击 Function 项目，编辑 <FunctionProjectName>.csproj.在下方添加Item，相对路径或绝对路径都可以.

If we need to add this file from anywhere locally, right click on Function project, Edit <FunctionProjectName>.csproj. Add Item below, relative or absolute path are both ok.

<ItemGroup>
  <None Include="c:\myapp\CanonicalMessage.xml">
    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
  </None>
</ItemGroup>
