尝试使用Google API v3检索我的youtube视频上传列表时，请求后是否不继续? [英] When trying to use google api v3 to retrieve my list of youtube videos uploads it's not continue after the request?

问题描述

该程序只是在尝试发出请求后挂起，并且从不继续. 尝试使用try和ctach，但不会引发任何异常或错误.

The program just hang after trying to make a request and never continue. Tried to use try and ctach but it's not throwing any exceptions or errors.

这是我在新课程中的代码:

This is my code in a new class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
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 Youtube
{


    class Youtube_Retrieve_Uploads
    {
        public Youtube_Retrieve_Uploads()
        {
            try
            {
                Run().Wait();
            }
            catch (AggregateException ex)
            {
                foreach (var e in ex.InnerExceptions)
                {
                    Console.WriteLine("Error: " + e.Message);
                }
            }
        }

        private async Task Run()
        {
            UserCredential credential;
            using (var stream = new FileStream(@"C:\jason file\client_secrets.json", FileMode.Open, FileAccess.Read))
            {
                credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    // This OAuth 2.0 access scope allows for read-only access to the authenticated 
                    // user's account, but not other types of account access.
                    new[] { YouTubeService.Scope.YoutubeReadonly },
                    "user",
                    CancellationToken.None,
                    new FileDataStore(this.GetType().ToString())
                );
            }

            var youtubeService = new YouTubeService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = this.GetType().ToString()
            });

            var channelsListRequest = youtubeService.Channels.List("contentDetails");
            channelsListRequest.Mine = true;

            // Retrieve the contentDetails part of the channel resource for the authenticated user's channel.
            var channelsListResponse = await channelsListRequest.ExecuteAsync();

            foreach (var channel in channelsListResponse.Items)
            {
                // From the API response, extract the playlist ID that identifies the list
                // of videos uploaded to the authenticated user's channel.
                var uploadsListId = channel.ContentDetails.RelatedPlaylists.Uploads;

                Console.WriteLine("Videos in list {0}", uploadsListId);

                var nextPageToken = "";
                while (nextPageToken != null)
                {
                    var playlistItemsListRequest = youtubeService.PlaylistItems.List("snippet");
                    playlistItemsListRequest.PlaylistId = uploadsListId;
                    playlistItemsListRequest.MaxResults = 50;
                    playlistItemsListRequest.PageToken = nextPageToken;

                    // Retrieve the list of videos uploaded to the authenticated user's channel.
                    var playlistItemsListResponse = await playlistItemsListRequest.ExecuteAsync();

                    foreach (var playlistItem in playlistItemsListResponse.Items)
                    {
                        // Print information about each video.
                        Console.WriteLine("{0} ({1})", playlistItem.Snippet.Title, playlistItem.Snippet.ResourceId.VideoId);
                    }

                    nextPageToken = playlistItemsListResponse.NextPageToken;
                }
            }
        }
    }
}

我使用了一个断点，当它在做直线时:

I used a break point and when it's doing the line:

var channelsListResponse = await channelsListRequest.ExecuteAsync();

它只是挂了程序，所以永远不会继续.

It's just hanging the program never continue.

推荐答案

我承认这不是理想的解决方案，而是可能的解决方案之一，但就我而言，我已经删除了"await"和* Async()关键字，并且现在可以使用.

I admit that it's not ideal solution rather one of possible but, in my case, I have removed "await" and *Async() keywords and it works now.

var channelsListResponse = channelsListRequest.Execute();

代替

var channelsListResponse = await channelsListRequest.ExecuteAsync();

还有

var playlistItemsListResponse = playlistItemsListRequest.Execute();

代替

var playlistItemsListResponse = await playlistItemsListRequest.ExecuteAsync();
