我正在尝试使用 Picasa Web Albums Data API 上传照片在 C# 中,我使用 RestSharp 来帮助我处理 HTTP 请求。

我有客户端 ID 和客户端密码,但我不知道如何将其放在 http 请求中以进行身份​​验证。

我收到错误:

Modification only allowed with api authentication.

返回的 StatusCode 是 Forbidden

这是我的代码,其中是我的用户 ID 和我的相册 ID。

“Authenticantion()”方法返回我已有的 token 。

var restclient = new RestClient(BaseUrl);
RestRequest request = new RestRequest("https://picasaweb.google.com/data/feed/api/user/<userID>/albumid/<albumID>") {Method = Method.POST};

最佳答案

OAuth2 身份验证通常发生在用户流程中,用户在该流程中使用用户进行登录并允许(或不允许)应用程序的某些范围(例如访问 Picasa,对 Google 云端硬盘只读)。

您可以通过此链接查看完整流程:OAuthPlayground .并在流程结束时获取您自己的 token 以用于您的 HTTP 请求。需要注意的一件事是刷新 token ,在 Playground 内可以设置为永不过期。但在现实世界中,您需要实现此刷新。

Picasa API 有点过时了,我建议您改用 GoogleDrive,它更加灵活并且是最新的。 GoogleDrive_API_Docs

也可以通过 OAuth2_ Server to server 进行此流程, 但我以前从未尝试过。
