【问题描述】：

我正在尝试转换此控制台应用程序：(https://developers.google.com/youtube/v3/docs/videos/insert)，其中包含使用 YouTube API 将视频上传到 YouTube 的代码。 我正在尝试将此代码放入 Azure 函数 并使用 Azure Blob 存储来存储我的 YouTube 文件。

我从一个简单的 Http 触发 Azure 函数开始，然后慢慢开始在函数中插入更多代码，但是在我这样做的过程中，我遇到了各种错误。这是代码，我正在尝试将其插入到我的 Azure 函数中：

using System;
using System.IO;
using System.Reflection;
using System.Threading;
using System.Threading.Tasks;

using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Upload;
using Google.Apis.Util.Store;
using Google.Apis.YouTube.v3;
using Google.Apis.YouTube.v3.Data;

namespace Google.Apis.YouTube.Samples

  /// <summary>
  /// YouTube Data API v3 sample: upload a video.
  /// Relies on the Google APIs Client Library for .NET, v1.7.0 or higher.
  /// See https://developers.google.com/api-client-library/dotnet/get_started
  /// </summary>
  internal class UploadVideo
  
    [STAThread]
    static void Main(string[] args)
    
      Console.WriteLine("YouTube Data API: Upload Video");
      Console.WriteLine("==============================");

      try
      
        new UploadVideo().Run().Wait();
      
      catch (AggregateException ex)
      
        foreach (var e in ex.InnerExceptions)
        
          Console.WriteLine("Error: " + e.Message);
        
      

      Console.WriteLine("Press any key to continue...");
      Console.ReadKey();
    

    private async Task Run()
    
      UserCredential credential;
      using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
      
        credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
            GoogleClientSecrets.Load(stream).Secrets,
            // This OAuth 2.0 access scope allows an application to upload files to the
            // authenticated user's YouTube channel, but doesn't allow other types of access.
            new[]  YouTubeService.Scope.YoutubeUpload ,
            "user",
            CancellationToken.None
        );
      

      var youtubeService = new YouTubeService(new BaseClientService.Initializer()
      
        HttpClientInitializer = credential,
        ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
      );

      var video = new Video();
      video.Snippet = new VideoSnippet();
      video.Snippet.Title = "Default Video Title";
      video.Snippet.Description = "Default Video Description";
      video.Snippet.Tags = new string[]  "tag1", "tag2" ;
      video.Snippet.CategoryId = "22"; // See https://developers.google.com/youtube/v3/docs/videoCategories/list
      video.Status = new VideoStatus();
      video.Status.PrivacyStatus = "unlisted"; // or "private" or "public"
      var filePath = @"REPLACE_ME.mp4"; // Replace with path to actual movie file.

      using (var fileStream = new FileStream(filePath, FileMode.Open))
      
        var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
        videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
        videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;

        await videosInsertRequest.UploadAsync();
      
    

    void videosInsertRequest_ProgressChanged(Google.Apis.Upload.IUploadProgress progress)
    
      switch (progress.Status)
      
        case UploadStatus.Uploading:
          Console.WriteLine("0 bytes sent.", progress.BytesSent);
          break;

        case UploadStatus.Failed:
          Console.WriteLine("An error prevented the upload from completing.\n0", progress.Exception);
          break;
      
    

    void videosInsertRequest_ResponseReceived(Video video)
    
      Console.WriteLine("Video id '0' was successfully uploaded.", video.Id);
    
  

【问题讨论】：

您遇到了哪些错误？

太多无法命名，但它们很少：找不到命名空间。另外，googlrwebauthorizationbtoker 不存在等等......我的问题是如何复制 YouTube 提供的代码示例并将其粘贴到中，作为 azure 函数？

@Thiago Custodio，名字太多，但很少：找不到命名空间。另外，googlrwebauthorizationbtoker 不存在等等......我的问题是如何复制 YouTube 提供的代码示例并将其粘贴到中，作为 azure 函数？

只是复制和过去是行不通的。您需要导入包：Google.Apis.Auth.OAuth2； Google.Apis.Services； Google.Apis.上传； Google.Apis.Util.Store； Google.Apis.YouTube.v3； Google.Apis.YouTube.v3.Data；

@Thiago Custodio，我也试过了。如果可能的话，您介意展示一下它应该如何设置吗？

【参考方案1】：

共享包含在 Azure 函数中的格式化源代码，但请注意，您将无法按原样使用它，因为它试图从本地路径访问文件。您可以进一步重构它并将可访问的文件路径作为输入参数传递。

在编译成功之前需要安装几个 nuget 包/依赖项

public static class Function1
    
        [FunctionName("Function1")]

【讨论】：

当我在 Visual Studio 上本地运行 azure 函数时，我不断收到此错误：“Executed 'Function1' (Failed, Id=84400f0c-b6e4-4c78-bf55-30c4527a8b5f) System.Private。 CoreLib：执行函数时出现异常：Function1。System.Private.CoreLib：找不到文件'C:\Users\Peter\Desktop\TestDemo\UploadVideo\UploadVideo\bin\Debug\netcoreapp2.1\client_secrets.json'。”我不知道如何解决这个问题。
