使用预先存在的访问令牌通过ASP.NET创建YouTube服务 [英] Creating a YouTube Service via ASP.NET using a pre-existing Access Token

问题描述

我一直在使用一个网站，用户可以将视频上传到共享的YouTube帐户，以便以后访问。经过大量的工作，我已经能够获得一个主动令牌和可行的刷新令牌。

I've been working on a Website for users to upload videos to a shared YouTube account for later access. After much work I've been able to get an Active Token, and viable Refresh Token.

然而，初始化 YouTubeService的代码对象如下所示：

However, the code to initialize the YouTubeService object looks like this:

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,
});

我已经有了一个令牌，我想用我的。我正在使用ASP.NET 3.5版，因此无论如何我都无法进行 async 调用。

I've already got a token, and I want to use mine. I'm using ASP.NET version 3.5, and so I can't do an async call anyways.

有没有办法在没有 async 的情况下创建 YouTubeService 对象，并使用我自己的令牌？有没有办法可以在没有授权经纪人的情况下构建凭据对象？

Is there any way I can create a YouTubeService object without the async call, and using my own token? Is there a way I can build a credential object without the Authorization Broker?

或者，应用程序使用YouTube API V2已经有一段时间了，并且有一个表单可以使用令牌，并针对与API V2中的令牌一起生成的YouTube URI执行了后续操作。有没有办法用V3实现？有没有办法使用Javascript上传视频，可能还有我可以在我的代码中使用的示例？

Alternatively, the application used YouTube API V2 for quite some time, and had a form that took a token, and did a post action against a YouTube URI that was generated alongside the token in API V2. Is there a way I can implement that with V3? Is there a way to use Javascript to upload videos, and possibly an example that I could use in my code?

推荐答案

注意：我最终将我的Framework升级到4.5以访问谷歌库。

NOTE: I ended up upgrading my Framework to 4.5 to access the google libraries.

要以编程方式初始化UserCredential对象，您必须构建一个Flow和TokenResponse。流程需要一个范围（也就是我们正在寻找凭据的权限。

To programatically initialize a UserCredential Object you've got to build a Flow, and TokenResponse. A Flow Requires a Scope (aka the permissions we are seeking for the credentials.

using Google.Apis.Auth.OAuth2;
using Google.Apis.Auth.OAuth2.Responses;
using Google.Apis.Auth.OAuth2.Flows;

string[] scopes = new string[] {
    YouTubeService.Scope.Youtube,
    YouTubeService.Scope.YoutubeUpload
};

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
    ClientSecrets = new ClientSecrets
    {
        ClientId = XXXXXXXXXX,  <- Put your own values here
        ClientSecret = XXXXXXXXXX  <- Put your own values here
    },
    Scopes = scopes,
    DataStore = new FileDataStore("Store")
});

TokenResponse token = new TokenResponse {
    AccessToken = lblActiveToken.Text,
    RefreshToken = lblRefreshToken.Text
};

UserCredential credential = new UserCredential(flow, Environment.UserName, token);
