Azure Functions中的运行时错误加载证书 [英] Runtime error loading certificate in Azure Functions

问题描述

我想创建一个Azure函数(C#API通用HTTP)方法，该方法将文件上传到Office365 Sharepoint文档库.

I want to create an Azure function (C# API Generic HTTP) method that uploads a file to an Office365 Sharepoint document library.

由于OneDrive API允许我上传大文件(使用守护进程和证书认证)，因此我已经成功地通过C#控制台应用程序实现了这一目标.

Because OneDrive API allows me to upload large files (using daemon process & certificate authentication), I have succeeded in achieving the goal with a C# Console Application.

现在的想法是将代码移到Azure函数中. 但是，在加载pfx-certificate时，函数运行期间出现错误.

The idea would be now to move the code into an Azure function. However, I receive an error during runtime of the function on the loading of the pfx-certificate.

public static async Task<bool> Run(HttpRequestMessage req, TraceWriter log)
{
   string certfile = System.IO.Path.Combine(Environment.ExpandEnvironmentVariable‌​s("%HOME%"), @"site\wwwroot\<functionname>\mykeyfile.pfx"); 

    X509Certificate2 cert = new X509Certificate2(certfile, "<myinsanepwd>");

    return true; //temporary 
}

X509Certificate2 cert行=新的X509Certificate2(certfile，");引发异常 System.Security.Cryptography.CryptographicException:系统找不到指定的文件.

The line X509Certificate2 cert = new X509Certificate2(certfile, ""); throws an Exception System.Security.Cryptography.CryptographicException: The system cannot find the file specified.

这真的很奇怪，因为该文件存在于指定的路径上(我在方法中使用File.Exists()进行了检查:)) 此错误是否与support.microsoft.com/en-us/kb/948154有关?我该如何解决?

This is really strange because the file exists on the specified path (I checked using File.Exists() in the method :) ) Could this error have something to do with support.microsoft.com/en-us/kb/948154 ? How can I solve this?

最诚挚的问候， 詹斯

推荐答案

添加X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable到构造函数.这段代码对我有用:

Adding X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable to the constructor. This code works for me:

using System.Net;
using System;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
    string certfile = System.IO.Path.Combine(Environment.ExpandEnvironmentVariable‌​s("%HOME%"), @"site\wwwroot\HttpTriggerCSharp4\myCertFile.pfx");        
    log.Info(certfile); 
    log.Info(System.IO.File.Exists(certfile).ToString());
    X509Certificate2 cert = new X509Certificate2(certfile, "password", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable);     
    log.Info(cert.Thumbprint);
