如何将某人的 youtube 帐户“链接”到我网站上的帐户？我正在尝试从视频中获取分析，他们赚了多少钱，等等。我知道我应该使用 YouTube 分析 API，但我看到大量不同的文档，它变得如此混乱。我可以使用任何 PHP 库来获取这些数据并将用户帐户链接到我的 Web 应用程序吗？我也对从哪里获得 OAuth 密钥感到困惑。
以下是我看过的一些网站：
1)站点一
2)站点二
在站点二，我查看了示例，但没有什么能真正帮助我理解如何开始。

A lot of the relevant info you'll need can be found in this document:
https://developers.google.com/youtube/analytics/authentication
Basically, it outlines the following 4 steps:
1) Register your web app in the Google Cloud Console
This is needed so you can get a client secret and client ID, which your server-side PHP code will need in order to do the oAuth flow (and get the right scope to be able to query analytics data for the user that's authenticating). See here for more info on how to do this:
https://developers.google.com/youtube/analytics/registering_an_application
The most important things to do as your register your app are to turn on the YouTube Analytics API and create a new client ID for your web application.
2) When a user visits your page, you'll need some way (i.e. a login button, for example) to trigger the start of the oAuth flow. When this is triggered, you'll want to redirect the browser to this URL:
https://accounts.google.com/o/oauth2/auth?client_id=[YOUR CLIENT ID]&redirect_uri=[THE URL YOU WANT THE USER TO BE DIRECTED TO AFTER AUTHENTICATION]&scope=https://www.googleapis.com/auth/yt-analytics.readonly&response_type=code&access_type=offline
This will present them with a window asking them if they want to give permission to your app to read their analytics. Note that the client id parameter is the same that you received when you registered your app in step 1. That registration process also will require you to set the allowed redirect URIs, so here you must pass one you set in the registration.
3) The redirect URL will be requested, from step two, by Google's servers with a "code" parameter attched. So when it is requested, it should immediately do a POST to another URL (i.e. with cURL or something similar), that looks like this:
POST /o/oauth2/token HTTP/1.1 Host: accounts.google.com Content-Type: application/x-www-form-urlencoded
code=[CODE THAT CAME IN AS A GET PARAMETER] &client_id=[YOUR CLIENT ID]&client_secret=[YOUR CLIENT SECRET]&redirect_uri=[THE REGISTERED REDIRECT URI]&grant_type=authorization_code
If you do it as a POST with cURL, then the response will be a JSON packet that has an access token and a refresh token.
4) Your php page can store these both (in your DB, for example), note that the user should be treated as logged in at this point, and you can use the access token in the header of all API requests send to the analytics API.
https://developers.google.com/youtube/analytics/authentication#OAuth2_Calling_a_Google_API
IT'll expire in an hour, so with each request you should be checking its age (i.e. when you stored it in the DB, you could store the expiry time, for example), and when you're getting close you can use the refresh token to get a new access token.
https://developers.google.com/youtube/analytics/authentication#OAuth2_Refreshing_a_Token
You can now redirect them to wherever your app needs them to be to start interfacing with the API.
Seems like a lot? It can be, but once you get the paradigm down it's pretty simple. And you asked about a client for PHP, and thankfully there is one:
https://github.com/google/google-api-php-client
It's got simple handlers for the whole oAuth2 flow, and also has a YouTube analytics service object that sets the access token automatically for you as it's making its various calls.
